• Domain Modeling - Encapsulation

  

  Date Published: 18 May 2022

  Domain models should encapsulate logic operations so that there is only one way to perform a given logical operation. That means avoiding exposing entity state and ensuring operations flow through specific methods. By funneling specific operations through specific code pathways, you can be sure constraints around the operations are enforced. In the previous article, I demonstrated some of the…

  
  

• Domain Modeling - Anemic Models

  

  Date Published: 11 May 2022

  When building a domain model, proper object-oriented design and encapsulation should be applied as much as possible.

• Grouping Assertions in Tests

  

  Date Published: 28 September 2021

  Although it's generally considered a best practice to assert only one thing per test, sometimes one logical "thing" may require multiple assertion statements to be executed. In such cases, it's helpful to be able to see all of the parts of the larger assertion that failed, so you don't end up chasing after them one by one. As an example, let's say you have a class that is initialized with its…

  
  

• GitHub Actions On Demand

  

  Date Published: 27 September 2021

  I use GitHub Actions a lot. They're a great tool for performing continuous integration (CI) and continuous deployment (CD) for your applications. However, by default they typically only are triggered by changes to your application's source code in the form of commits and/or merges/rebases. This means that to trigger a particular workflow, you usually need to make a commit, and obviously this can…

  Date Published: 16 September 2021

  I like to use an index card as a bookmark when I'm reading non-fiction books, so that I can come back to interesting topics later or review certain points in an article of my own, like this one. Usually one index card is sufficient, but in reading Dependency Injection: Principles, Practices, and Patterns by Steven von Deursen and Mark Seemann(affiliate link) I filled two front and back.

• Should Controllers Reference Repositories or Services

  

  Date Published: 14 September 2021

  Last updated: 13 October 2023 A common question students ask when learning about Clean Architecture, SOLID, and/or Domain-Driven Design (DDD) is whether controllers (or razor pages or API Endpoints should work with repositories directly, or if they should only communicate with services. As with many questions in software, the answer is, "it depends", but I can offer some recommendations. A related…

To demonstrate this concept, I'm…

  
  

• Comparing Techniques for Communicating Between Services

  Date Published: 24 August 2021

  In distributed software applications, different services or processes or apps frequently need to communicate with one another. Modern architectural trends toward microservices and containers and cloud-native apps have all increased the likelihood that apps will increasingly be deployed not as single monoliths, but as collections of related services. There are only so many different ways these…

• Improving Method and Function Clarity

  

  Date Published: 22 June 2021

  (Originally sent to my weekly tips subscribers in March of 2019) When you look at a method or function, it should have a name that describes what it does. Naming things is hard but important, and probably the most important thing you can do when you design a method is give it a good name. This mainly applies to methods (or functions) that are or may be called from more than one place. It's less…

  Date Published: 15 June 2021

  It's not unusual to have different levels of prioritization in backend systems. Imagine you have a process that generates and sends reports that users have requested. Some of these might be low-priority reports that are simply generated periodically so they're available to view, while others might be generated on demand, with a user actively waiting for the results. These could be further…

  
  

• C# Generics Best Practices

  

  Date Published: 08 June 2021

  There was a time when C# didn't support generics. It was a dark time. Ragged bands of .NET developers roamed the harsh landscape, copy-pasting strongly-typed list implementations to avoid the evils of primitive boxing operations. Forced to choose between loose typing and explicit casts at every turn, would-be developers of strongly-typed object models somehow managed to endure and ship (mostly…

  
  

• What If Product Owners Reported to Dev Teams?

  

  Date Published: 01 June 2021

  In most organizations, if there's a Product Owner, the dev team is generally subservient to it and charged with building whatever the Product Owner comes up with. That's not to say they aren't often "on the same team", but the flow of responsibility is usually the PO pushes new requirements and the developers respond to them. Sometimes this relationship, even if only implied, has ramifications for…

• Testing Exceptions with xUnit and Actions

  

  Date Published: 14 April 2021

  When you're writing unit tests for a method, it's a good idea to test various failure conditions ("sad paths") in addition to testing the expected, everything is working condition ("happy path"). In particular, if you have a method that may throw exceptions, especially if they're custom domain exceptions, you should be sure you're testing this behavior. Another common source of exceptions is guard…

  Date Published: 07 April 2021

  I've been using docker-compose quite a bit lately for a distributed app that includes 3 front end apps, 2 databases, RabbitMQ, and PaperCut (test email server). For the most part, this works great as a way to encapsulate all of these processes and run them in a containerized manner so that everything works together.

  Date Published: 16 February 2021

  Two terms that come up frequently when discussing software development in .NET and C# are DTO and POCO. Some developers use these terms interchangeably. So, what is the difference between a DTO and a POCO? First, let's define each term. Data Transfer Object (DTO) A DTO is a "Data Transfer Object". It's an object whose purpose is to transfer data. By definition, a DTO should only contain data, not…

  Date Published: 16 December 2020

  A common feature of distributed architectures is message-based communication between systems or microservices. Whether using a message bus or queue, messages provide a means of reducing coupling between systems, allowing overall systems to remain available even when some subsystems are not. However, when designing the messages that will be used in such systems, care must be taken to include…

  
  

• Avoid Wrapping DbContext in Using (and other gotchas)

  

  Date Published: 01 December 2020

  EF and EF Core DbContext types implement . As such, best practice programming suggests that you should wrap them in a block (or new C# 8 using statement). Unfortunately, doing this, at least in web apps, is generally a bad idea. I work with a lot of clients who are migrating from .NET Framework to .NET Core and .NET 5.

  Date Published: 17 November 2020

  CAP Theorem (wikipedia) is a classic "given 3 choices, choose 2" topic. The three choices are Consistency, Availability, and Partition Tolerance. You can't have all three. CAP Theorem Given distributed data or systems, the choice mostly comes up when there is a network partition, meaning two nodes of the system can't communicate immediately with one another. At that point there is a partition, and…

  This is the fourth of the 5 Laws of Software Estimates. I expanded on the third law of software estimates in my previous article. Estimates are made for a given point in time, when a certain set of information and assumptions are known and held. As time passes, new information becomes available and assumptions change. The older the estimate, the more likely it is to be stale. Since by definition…

  I recently needed to find which of a bunch of markdown files had a particular string in them. My initial thought, since I'm on Windows, was to use Windows File Explorer's search dialog. No dice - it found no results when I knew there were some. I did a quick search for 'windows explorer search markdown files' which led me to a Super User thread that said I'd have to install a Markdown Preview to…

  
  

• Domain-Driven Design with ASP.NET Core Workshop

  

  Date Published: 27 November 2019

  I first learned about Domain-Driven Design, or DDD, over ten years ago. Since then, I've given more workshops on the topic, both public and private on sites, than I can remember. Julie Lerman and I also published a very popular course, DDD Fundamentals, on Pluralsight, which I expect we will refresh in the coming year. (By the way, there's a 40% off sale for Black Friday going on now (as I write…

• Sketch Themes for Prototypes

  

  Date Published: 30 October 2019

  Last week during one of my devBetter coaching sessions, the conversation turned to spikes and Minimum Viable Products (and even not-so-viable products). Sometimes, in order to get rapid feedback, it's useful to throw together a prototype that has literally nothing going on in the backend, but lets the user get a sense of how the application would flow. The problem, of course, is that once users…

• Running Integration Tests in Build Pipelines with a Real Database

  

  Date Published: 16 October 2019

  Last updated: 13 October 2023 A pain point for some organizations is figuring out how to run tests that involve databases. These are not unit tests, by most folks' definition (including my own: unit test or integration test and why you should care). Nonetheless, they're important and ideally they should run as part of your build pipeline. Recently I've come up with a technique that works quite…

  
  

• Configure Different Implementations for Different Controllers in ConfigureServices

  

  Date Published: 09 October 2019

  You may find yourself in a position where you need to have two (or more) different implementations of the same interface within your ASP.NET Core application. This may be because your application is too big to allow you to fully replace one implementation with another all at once, so you're rolling out the updates one type at a time. Let's say the services in question relate to persistence, and…

  Date Published: 18 September 2019

  Technical Debt is a metaphor for shortcuts and hacks in software that make it more difficult to change and maintain than it could be with an optimal design. Many applications have accumulated a large amount of technical debt, and figuring out how to deal with it is a fairly common challenge for many developers, especially senior developers starting new contracts or jobs at companies that need help…

  Date Published: 11 September 2019

  Last updated: 13 October 2023 A frequent question I hear from clients is some variant of "Ok, Continuous Integration is great, but how do we get everybody on the team to pay attention to it?" This is obviously a bigger problem if the question is coming from a lone junior developer, as opposed to a technical manager. In the case of the junior developer, they may need some help convincing the rest…

• Configure Visual Studio to Name Private Fields with Underscore

  

  Date Published: 20 August 2019

  Last updated: 13 October 2023 Most C# coding standards recommend using camelCase for local variables and _camelCase for private or internal (and I also say for protected, but that's just me) fields. Unfortunately, out of the box Visual Studio just uses camelCase for these fields, which makes typical dependency injection scenarios annoying in constructors: I much prefer this version: Fortunately…

  
  

• Using Multiple Solutions in Visual Studio

  

  Date Published: 14 August 2019

  I've given this advice quite a number of times so I figured it was time to put it into an online article. If you're a .NET developer you probably use or have used Visual Studio. Visual Studio has two kinds of project organization file formats: projects and solutions. Solutions are essentially groups of projects. Most software applications involve more than one project, and so virtually every…

  
  

• Minimize new in Automated Tests

  

  Date Published: 07 August 2019

  Last updated: 13 October 2023 Automated tests have gained a lot of acceptance in recent years. Not long ago, many organizations bristled at the notion of having their expensive developers spend time writing code that wasn't actually going to ship to production, but instead would just verify that the "real" code worked. Today, the idea that testing in many instances is something computers can do…

  Date Published: 29 July 2019

  If you're working with git, especially with open source, sometimes you'll find that you want to work with a particular pull request, or PR, locally. Maybe you're reviewing the PR and instead of just eyeballing it in the browser you want to actually run the code and see what it does (novel idea, I know!). In any case, actually getting the code from a PR, especially one from a fork that isn't even…

  Date Published: 14 April 2019

  Windows Azure offers support for RDNS (PTR) records, which are used to get a hostname from an IP address (the opposite of what DNS does, hence the name). Microsoft has an article that describes how to set RDNS up, but it assumes you've already installed the azure CLI tools. Since I'm going through the process from scratch, I thought I'd share the full process here. You'll need to have npm…

  
  

• Add HTTPS To Any Site For Free

  

  Date Published: 06 March 2019

  Back in the old days, adding HTTPS/SSL/TLS to secure a web site was a big deal. You had to spend hundreds of dollars for a certificate, then install it on the web server. It had to be specific to the subdomain you were using, or you had to shell out even more bucks for the wildcard cert. And they’d expire sometimes, and your site would go down, and that was never fun. Times have changed. Yes, you…

  Date Published: 07 March 2018

  When looking at tuning application performance, a common principle to follow is this one: Maximize the amount of work not done. It's hard to make doing something faster than doing nothing, so do nothing whenever you can. A common way to do very little is to queue up work (in the form of a Command, typically) so that some other process can actually perform the work later. However, you can also…

  As I'm working with JavaScript and TypeScript more and more these days, I often find myself wishing for LINQ statements to use to easily work with collection data. Fortunately, there are equivalents for all of the most common LINQ statements, and with ES6 arrow functions the syntax is also very concise and familiar. You can see them in action in this fiddle, or just check out the code here…

  
  

• Applying the Builder Pattern to Improve an Angular Service

  

  Date Published: 30 January 2018

  Angular - Typescript Recently I was working on an Angular/Typescript service that was building up some navigation-related properties, driving the menu of a SPA application. The existing service had a helper method that took in two arrays full of potential validation issues on the SPA’s different tabs, and based on these it would return an appropriately-styled and configured Tab object. Initially…

• Listing Strongly Typed Enum Options in C#

  

  Date Published: 28 November 2017

  In a previous article, I wrote about the Strongly Typed Enum Pattern in C#, which can be used in place of the built-in enum. Read that article to get a quick understanding of why you might not want to use enum types. Go ahead, this article will still be here. Ok, so in that example, I had a list of options (for instance, Roles) that I wanted to represent using objects instead of primitive enum…

  
  

• Keep master and origin branches working if possible

  

  Date Published: 22 November 2017

  Here are two tips that teams I work with have found useful when working with git for larger projects with many team members that I thought I would share: Only merge into master if code is working The first tip is that you should only merge (or commit, but that should be rare) into master if your code is working. That is, it compiles and all of its tests run, and not just on your own machine, but…

  
  

• Displaying and Setting Current ASP.NET Assembly Version

  

  Date Published: 15 November 2017

  When you’re building web applications and you’re setting up continuous integration and delivery pipelines, it’s worthwhile to know which particular version of the application is deployed to a given environment. One of the easiest ways to share this information is from the application itself. Many sites will display build or version information in their footer or on a particular page. You can do…

  
  

• Razor Pages Model NullReferenceException

  

  Date Published: 14 November 2017

  Here’s a quick tip: If you’re adding a new Razor Page to an ASP.NET Core 2.0+ project, and you add a codebehind model class, but then when you try to use it you get a NullReferenceException, this might be why. First, specify the model correctly from the razor page (Index.cshtml): If you’re literally adding just one page to your project, you need to make sure you specify the full namespace of the…

  
  

• Enforcing Model Validation Policy in Web APIs

  

  Date Published: 09 November 2017

  If you’re exposing a Web API, one of the most basic things you should be doing on every request, and especially on those requests that mutate your system’s state, is ensuring that the data you’re accepting is valid. ASP.NET Core MVC (and Web API 2 and MVC 5, too!) supports model validation as part of the model binding process. You’re likely familiar with it and have seen it used in combination…

  
  

• Encapsulation in Objects and Applications

  

  Date Published: 01 November 2017

  Encapsulation is a key principle of software development in general, and object-oriented design in particular. It refers to the ability for constructs (objects, functions, other things) to expose a public interface with which clients can interact, while keeping their internal implementation hidden. Encapsulation offers a host of benefits, most important being to allow the construct in question to…

  Date Published: 05 October 2017

  There’s a minor breaking change in ASP.NET Core 2.0 that I’ve encountered while updating my Clean Architecture sample. In 1.x, you could configure EF Core to use an In Memory database, and when you did so, you could optionally specify a name: One of the most common scenarios for using an in memory database is for testing. Unfortunately, the state of the in memory database is not reset between test…

  
  

• Your API and View Models Should Not Reference Domain Models

  Date Published: 03 October 2017

  If you’re organizing your application following Clean Architecture and Domain-Driven Design, with your Core domain model in one project that is referenced by your UI and Infrastructure projects, you should be careful what you expose in your client-facing models. Client facing models typically reside in the UI layer as ViewModels or ApiModels, or they may be called DTOs (Data Transfer Objects). In…

  
  

• Better Performance from Async Operations

  

  Date Published: 25 September 2017

  The C# language has had support for the async and await keywords (and yet another new way to perform asynchronous operations) for a while now. They’re still confusing to many developers (including me sometimes!) and can be a source of many pitfalls. I mostly work in ASP.NET projects, and the default project templates have all been using async for some time. New developers often assume this is…

• ASPNET Core Razor Pages – Worth Checking Out?

  

  Date Published: 31 August 2017

  You may have heard that in ASP.NET Core MVC 2.0, there is a new feature called Razor Pages. This feature allows you to create pages that don’t need to have a controller or action, and which can optionally have an associated PageModel class instead of a ViewModel. If you’ve been programming for a while, especially in the ASP.NET space, this may trigger some immediate reactions. Oh no! The return of…

• Breakpoint Labels in Visual Studio

  

  Date Published: 29 August 2017

  Breakpoints offer a great way to debug our software, letting us literally stop time during code execution and inspect what's going on at that moment. It's a bit like being a speedster like Quicksilver, who can almost stop time and manipulate the environment between moments in time: Unfortunately, in larger applications, we may find that we have quite a few places where we might want to stop and…

  
  

• Troubleshooting Razor Pages and PageModel Classes

  

  Date Published: 27 August 2017

  When using the new Razor Pages feature in ASP.NET Core 2.0, you can (and usually should) define a separate “codebehind” file for your PageModel class. If you’re using Visual Studio, this class will be associated with your Razor Page as a nested file in the Solution Explorer, making it easy to locate. The class will also be easier to unit test than if you were to put your functionality directly…

  
  

• Debugging ASPNET Core Routes

  

  Date Published: 23 August 2017

  Routing in ASP.NET MVC apps has often presented challenges to developers, resulting in a bunch of different route debugging tools and nuget packages. In ASP.NET Core, there tends to be less routing confusion because of the emphasis on attribute routing, rather than the traditional routing tables. With ASP.NET Core 2.0 and Razor Pages, this trend continues since Razor Pages use convention-based…

  String interpolation is one of my favorite features in C# 6. It lets us replace this kind of code: with this: In Entity Framework Core 1.x, you could use string interpolation for SQL queries, but it would just perform literal string interpolation. For example, consider this code: This will result in the literal SQL string: Running this on your database is likely to result in an error like this one…

• Logging and Monitoring are Requirements

  

  Date Published: 08 August 2017

  It’s common in many applications to see logging and monitoring added into the code as an afterthought. It’s rarely included in the specification for a feature or product, and it’s rarely tested. Thus, it’s often inconsistently implemented. One approach to addressing this is to use techniques like AOP to broadly and consistently add logging via rules. However, this often falls short and doesn’t…

  
  

• Testing Logging in ASPNET Core

  

  Date Published: 08 August 2017

  When it’s important, logging should be considered a “real” requirement, not just a developer or operations afterthought. In many cases, especially diagnosis of production problems, logging has real business value. Thus, there are times when you’ll want to test that your logging works. Consider the following function: Let’s assume for a moment that when this exception occurs, it’s potentially…

• Switch Between git Branches Easily

  

  Date Published: 18 July 2017

  I recently ran across a great tip from Kevin Griffin for how to quickly switch from your current git branch to your previous one: Instead of typing out the full name of the branch when using git checkout, you can simply specify – (minus or dash) to refer to the previous branch. Now think about how you’re going to put all those saved keystrokes to good use.

  Date Published: 31 May 2017

  There are two ways to get rid of untracked files from your git working tree. The first one, which many of us have done, is to simply go to a new folder (or delete the current one) and perform a fresh git clone operation. This “burn it to the ground and start from scratch” approach works, but there is a more elegant solution: git clean. To use git clean, it’s a good idea to first run it with the -n…

  Date Published: 17 May 2017

  It's not unusual in applications to have a few constants defined for things you know are never going to change (so you don’t need to store them in the database, or if they are in the database, you don’t need to fetch them every time you need them).

• Use an Integrated Shell Console Terminal in VS Code

  

  Date Published: 05 January 2017

  VS Code is a lightweight code editor available for free from Microsoft. It’s a great, open-source tool for quick edits, or even for all day coding. While I think most users of VS Code are comfortable having it open separately from their command line environment, you can also host an integrated shell (console or terminal) within VS Code itself. This can be nice if you want to use it in full screen…

• Avoid Referencing Infrastructure in Visual Studio Solutions

  

  Date Published: 14 December 2016

  The dependency inversion principle states that your application’s abstractions should not depend on implementation details, but rather implementation should depend on abstractions. In Clean DDD architected applications, you’ll typically have a class library called Core (or something similar) which houses the domain model, including the main abstractions. Your implementation libraries…

  
  

• The Minimal ASPNET Core 1.1 App

  If you’re trying to get the ASP.NET Core Status Code Pages middleware to work, but it just is ignored no matter what, one thing to check is the rest of your middleware pipeline. If you have middleware that is writing anything to the response, it will cause the status code pages middleware to be ignored.

• Avoid Storing Database Credentials in Source Control

  

  Date Published: 19 October 2016

  Your application probably needs to communicate with a database of some kind. Naturally, that database isn’t open to the world – it needs to be protected and secured. The typical solution to this is to create a username and password combination (ideally, specific to each application or user that requires access) and configure the application with these credentials. In many cases, they’re simply…

• Configuring ASPNET Core Apps with WebHostBuilder

  

  Date Published: 09 September 2016

  In ASP.NET Core apps, you typically configure the application in Startup. However, the application itself runs inside of a host, which is configured separately using a WebHostBuilder. Although it’s not the default, recommended case (and thus isn’t shown in the official docs), you can actually configure the application directly from WebHostBuilder and avoid using a Startup class entirely (or…

  
  

• Specifying API Routes in ASPNET Core

  

  Date Published: 08 September 2016

  ASP.NET Core uses attribute routing to determine the behavior of web APIs. Its integrated support for MVC and Web API is one of my favorite features, since working with MVC 5 and Web API 2 was painful due to the similarities but separate implementations of the two stacks. When creating routes for your APIs, a common approach is to use something like this: When applied to a particular API…

• Refactoring Static File System Access

  

  Date Published: 16 August 2016

  Years ago, I was trying to test an application I’d written, but couldn’t figure out how to remove a dependency it had on the file system. At the time, I was familiar with unit testing, and had bought into its value both as a developer and as a business owner (this was software that was central to my business at that time), but I was stymied by some code that looked something like this: `public…

  
  

• Refactoring Static System Clock Access

  

  Date Published: 10 August 2016

  If you have logic that depends on dates and/or times, it can be difficult to test if it’s directly accessing the system clock (via DateTime.Now in .NET, for example). This is an example of an insidious dependency that can add unnecessary coupling to an application, making it harder to maintain. Fortunately, it’s pretty easy to refactor your code to address this issue. First, realize that you don’t…

  
  

• Real World ASPNET Core MVC Filters

  

  Date Published: 08 August 2016

  Filters are a great, often underutilized feature of ASP.NET MVC and ASP.NET Core MVC. They provide a way to hook into the MVC action invocation pipeline, which makes them ideal for pulling common repetitive tasks out of your actions. Often, an app will have a standard policy that it applies to how it handles certain conditions, especially those that might generate particular HTTP status codes. Or…

  Date Published: 03 August 2016

  A common but insidious dependency in many .NET applications is their use of configuration, including appSettings. The main issue is static access to config for values that affect the behavior of the application (values that are simply displayed, or used for things like email servers or addresses, aren’t usually an issue). Imagine you have some code like this: Imagine this method is used to gather…

• Multi-Term jQuery Table Filter

  

  Date Published: 30 June 2016

  Recently I was mentoring a client who needed a simple filter for a table of data. In this case, they weren’t using a viewmodel-based framework, so it wasn’t an option to simply modify the collection to which the table was bound. We needed to use old school jQuery.

  Date Published: 17 April 2015

  I've been a participant in a number of software developer user groups for many years, and an organizer of the Hudson Software Craftsmanship group since 2009. A few years ago, I was a member of the INETA Speaker Bureau, and would travel to a number of user groups around the country (and occasionally, the world - including Moscow in 2006). Recently I participated in a discussion about things to…

  
  

• GitHub Spinoff Sites

  

  Date Published: 14 April 2015

  Recently I’ve started using a couple of GitHub-related sites for collaboration. These are made possible by GitHub’s open API, and demonstrate how shipping an API allows a community to develop around your product, which in turn makes it more difficult for a competitor to displace your users. I’m sure there are many other sites out there, but the two I’m using at the moment are Huboard and Gitter.im…

  Date Published: 06 April 2015

  Configure Grunt in Visual Studio 2015 You can easily configure Grunt to perform client-side build tasks in Visual Studio 2015. Grunt is very similar to Gulp, and either one can be used with Visual Studio 2015 to perform a variety of tasks. Although it’s supported, you need to add it to the project as a dependency before you can start working with Grunt. In this example, we are going to configure…

  A new feature inGlimpse.AspNet1.9.2 will display whether each assembly in your web site’s bin folder was compiled in Debug or Release mode. At development time, Debug mode is fine, but you want to avoid shipping Debug assemblies to production since there are performance costs associated with these assemblies.

  Date Published: 10 September 2014

  Obviously it’s very easy to download and reuse images on the Internet. However, if your business depends on such intellectual property, you may need to take steps to prevent unauthorized usage of your images. There are many ways you can mark your images to later prove they are yours – that’s a topic for another day – but you may not know there is also a very easy way to find other images and where…

  When working with any ORM tool, it can sometimes be helpful to see just what, exactly, is being sent to the underlying data store. This can help identify bugs as well as performance issues in how the query is being performed (or how many queries are being performed, in the case of SELECT N+1 problems). There are several existing tools available that provide assistance with this: SQL Server…

• Where to Declare Variables in C# and JavaScript

  

  Date Published: 16 July 2014

  Both JavaScript and C# belong to the C family of languages. They share curly braces and semi-colons, and in fact there are many cases where the exact same code will execute (correctly, in most cases) as either language. However, there are certain best practices that are unique to each language, and where variables should be declared is one of them. Declaring Variables in C# In C#, it’s generally…

  
  

• Ensure You Are Not Adding To Global Scope in JavaScript

  

  Date Published: 15 July 2014

  A key best practice if you’re writing JavaScript code is to avoid adding objects to the global scope. There are several good reasons for this – globals add coupling, it makes it easier for disparate libraries to break one another, etc. A general rule of programming is to avoid global scope, in fact. Unfortunately, JavaScript makes adding things to global scope very easy. Consider this bit ofcode…

  Date Published: 14 June 2014

  In PowerPoint, especially if you’re working with a complex slide with a lot of animations, it can be difficult to easily determine which named element corresponds with which visual element on the slide. By default, when you add pictures and other assets to a slide, they get names like ‘Picture 5’.

• Tip – Override ToString() in Objects

  

  Date Published: 12 June 2014

  Most of your domain objects should override ToString() for the simple reason that if you ever want to simply display the object’s state, you shouldn’t need to implement a custom formatter for it. Furthermore, it’s well-known that the default System.Object implementation of .ToString(), which outputs the type’s name, is useless 99% of the time. Thus, it’s generally a good idea to implement…

  I recently moved the DevMavens.com site from one server to another and needed to ensure that the www.devmavens.com domain correctly redirected to simply devmavens.com. This is important for SEO reasons (you don’t want multiple domains to refer to the same content) and it’s generally better to use the shorter URL (www is so 20th century) rather than wasting 4 characters for zero gain.

• When Should You Refactor

  

  Date Published: 03 January 2014

  A common question teams face is, when should we take the time to refactor our code? Refactoring is defined as improving the design or quality of code, without changing its external functionality. Most teams face constant pressure to release features and/or fix bugs as quickly as possible, so it’s not uncommon for problems discovered in the codebase to be put on the back burner to be fixed “later…

  Date Published: 09 May 2013

  My opinions on comments in software code have evolved with my experience. When I was a teenager first learning to program for real, I rarely used comments unless the code was for an assignment, in which case it was a forced exercise every bit as much as teachers’ requests to “show your work” added verbosity to my math and science problems’ solutions. Of course, the programs themselves were quite…

  Date Published: 06 November 2012

  If you’re a developer running SQL Server locally, you may sometimes need to limit how much memory the database is consuming.

• Joining Telerik

  

  Date Published: 26 April 2012

  Earlier this year, I wrapped up my work with The Code Project and Lake Quincy Media and returned to NimblePros, the consulting company Michelle and I started a few years ago and which she’s run quite successfully the last few years. NimblePros has been doing some great things the last couple of years, with revenues in 2011 doubling those of 2010. At the same time, we’ve been watching Telerik…

• Modifying and Disabling Hyperlinks using jQuery

  

  Date Published: 13 April 2012

  I have a simple menu in an ASP.NET MVC application allows a user to take one of several actions after first selecting a resource to work with from a drop down list / select box or textbox. In the case where the user hasn’t yet selected anything (or entered any text), I want the links to be disabled, as I’d rather let the user know the issue on the current dashboard page than have them go to a page…

  
  

• New is Glue

  

  Date Published: 13 April 2012

  When you’re working in a strongly typed language like C# or Visual Basic, instantiating an object is done with the new keyword. It’s important that we recognize the significance of using this keyword in our code, because I would venture to say that well over 90% of developers don’t give it a second thought. Most developers have, at one time or another, heard the practice of building software…

  
  

• Beyond Role Based Authorization in ASPNET MVC

  

  Date Published: 11 April 2012

  A fairly frequent requirement in applications is to check for authorization to perform an action. At the most basic level, this might just involve seeing if the user is authenticated (at all) or checking a flag to see if they are an Admin. However, more complex requirements frequently include a variety of roles, and it’s quite common for the notion of ownership to be involved as well, with some…

  
  

• Configuring Web Apps To Behave Like Native Apps on iOS

  

  Date Published: 27 March 2012

  There are a number of things you can do with your web-based application to have it behave like a native iOS application. One of these I mentioned previously, which is to disable the user’s ability to zoom in and out using pinch gestures. In addition, you can hide the Safari user interface “chrome” so that the user is unaware they’re in a browser. You can also add splash screens and customize the…

  
  

• Asus Zen Ultrabook Revisited

  

  Date Published: 27 March 2012

  A couple of months ago I got an Asus Zen ultrabook, which I posted about when I first got it, and a month or so later. Now that I’ve had it a while, I thought I’d post one more time with how it’s continued to work for me. I’m still very happy with its look, feel, and speed. It’s very responsive both while up and running and when waking up or shutting down. One thing I wish it came with is an HDMI…

  
  

• How Do I Disable Zoom in an iPad iPhone Mobile Web App?

  

  Date Published: 26 March 2012

  If you’re building web-based applications for mobile devices like the iPad/iPhone and you want to mimic native applications’ look and feel and experience, one thing you may want to do is disable the pinch zoom gesture. Most native applications don’t offer support for this, but of course most mobile browsers currently do, so a sure way for users to tell that they’re actually viewing a web page is…

You’re using Visual Studio 2010, and everything is going great until you get to the part where you wanted to make an HTTP request. You know you can do this, you’ve done it before, heck, you might even be…

  Not long ago, while preparing my Kanban Fundamentals video training class for Pluralsight, I read Personal Kanban, by Jim Benson and Tonianne DeMaria Barry. If you’re new to the concept of kanban, this book is a good place to get started (along with my course, which is about 90 minutes long, and shorter if you speed it up). I read the kindle edition of Personal Kanban, even though I don’t own a…

• Sending Email from a Sitefinity Module with Attachments

  

  Date Published: 24 February 2012

  A fairly common use case in web applications is the need to send an email, and applications built on top of Telerik Sitefinity are no different. Since modules are simply .NET DLLs, you’re free to write whatever code you like, so it’s certainly possible for you to write a module that sends emails in a way that knows nothing about Sitefinity. However, if you want to interact with Sitefinity, for…

  Date Published: 09 February 2012

  In working on a client’s reporting system, I ran across some StackedBar charts that were using the System.Web.DataVisualization.Chart control that were having some problems. The biggest one was that the rendered bars had gaps and floating rectangles in it. This turned out to take about an hour to solve, using my best Google-fu, so I’m posting my solution and notes here, in case I run into it again…

• Unit Test or Integration Test and Why You Should Care

  

  Date Published: 19 January 2012

  There remains a fair bit of confusion about what constitutes which kind of test. Many developers are fairly new to testing, and tend to call any tests of their code “unit tests” even when they’re dealing with something substantially larger than a unit. The tools don’t really help much here, since the various test runner frameworks all call themselves unit test frameworks, and the various test…

  Date Published: 19 January 2012

  If you’re at all serious about testing, at some point you’re going to have a rather large suite of tests that need to run, and you’ll find that your builds are taking longer than you would like because of how long the tests run. For example, consider this suite of 24 tests, each one of which looks like this one: If you run 24 of these, it’s going to take about 24 seconds, by default: Now of…

• Represent Behavior with Classes not Flags

  

  Date Published: 11 November 2011

  In any non-trivial software applications, there will be different kinds of behavior attributed to different kinds of objects. For instance, maybe a discount is only applied to some products, but not others. Or a validation rule is applied in most cases, but not for this particular class of item. Perhaps an email-sending application should perform some checks to insure it has certain elements…

• Inner Fields and Lazy Initialization in C#

  

  Date Published: 29 October 2011

  Using lazy initialization in C#, a class’s state is set up such that each property’s get method performs a check to see if the underlying field is null. If it is, then it calculates or populates the field before returning it. This is a very simple and common approach, but it requires that the class follows a convention of only accessing the field via the property. Unfortunately, there are no…

• Configuring a WCF Service to Run Via HTTPS

  

  Date Published: 22 April 2011

  Yesterday I wrote about how to wire up jQuery UI’s AutoComplete add-in to a WCF Service to create an autocomplete search/navigation control. Today I deployed the resulting code to production but initially had some trouble getting things to work. The only real difference between the two environments is that in production everything goes through HTTPS/SSL, so I figured that had to be the culprit. A…

  Date Published: 22 February 2011

  Introduction Sometimes your domain objects have one-to-many or many-to-many relationships with other objects. For instance, your Customers might have collections of Orders associated with them. The simplest way to model this is to expose a field or property off of your Customer class. Unfortunately, this has a number of negative consequences because of how it breaks encapsulation. Fortunately…

  If you ask a newly-hired developer this question while they are busy coding away on something, you’ll usually get an answer like “the Acme project.” If that’s too obvious (after all, maybe that’s the only project this dev works on), then the answer might be “the new xyz feature” or “that abc bug.” All of these are more-or-less valid responses, and depending on the scope of the response, they might…

  
  

• Building a CachedRepository via Strategy Pattern

  

  Date Published: 15 February 2011

  In part one of this series, I introduced the CachedRepository pattern, and demonstrated how it can be applied through the use of simple inheritance to an existing Repository class.

  This wraps up my mini-series on using PowerShell to help manage services running on multiple remote servers. In my case, these scripts exist to make it easy for me to globally start and stop services on a number of web servers that are part of Lake Quincy Media’s AdSignia ad platform – you can read more about the message-based architecture we’re using here. I learned the basics of starting and…

  
  

• Pass Results from One PowerShell Script To Another

  

  Date Published: 06 February 2011

  If you’re using PowerShell but want to keep your scripts DRY, you may want to factor common functions into their own scripts, and then call these scripts from multiple other scripts. This is pretty easy to do. For instance, if you have an array of values that you want to use as inputs for several scripts, you could create a file like this one: Colors.ps1 Now, to use this in another PowerShell…

  
  

• Message-Based Architecture Goodness

  

  Date Published: 06 February 2011

  Recently at Lake Quincy Media we upgraded our logging system for the AdSignia ad platform so that it uses messaging rather than direct SQL database access. This allows us to log much more detailed data, which we can then analyze, and also improves the performance of every ad request, since it eliminates a database call and replaces it with a local queue operation, which is much faster and less…

  Date Published: 10 January 2011

  I’ve been writing tests and unit tests for quite a while, and naturally my personal preference for naming them has evolved somewhat with time.

  Date Published: 17 September 2010

  Using Visual Studio 2010 (and some earlier versions), it’s very easy to create a WebTest by recording one or more web requests to the system under test (SUT). To get started, open Visual Studio 2010 and create a New Project. Then select Test Project like so: Next, add a Web Test to the project, and hit the URL you want to test (the one that accepts multiple different parameters that you want to…

  
  

• An IIS Crash Analysis Story

  

  Date Published: 17 September 2010

  Last week I attempted to update a high-traffic production ASP.NET application to ASP.NET 4. In the course of doing so, I was surprised, despite having tested everything thoroughly in a staging environment, to find that under production loads, the system was erratic and slow to respond to requests. Further inspection revealed that IIS was actually crashing under load, leaving a cryptic message in…

• Real World Monitoring and Tuning ASP.NET Caching

  

  Date Published: 08 September 2010

  First off, let me direct you to a great article on monitoring your ASP.NET cache API behavior. Go read that first, then come back here. Done? Good, so let’s make the advice from Simon’s blog a bit more concrete with some real-world examples. Consider this fairly high-traffic web server’s behavior (avg. 55 ASP.NET requests/sec, 110 max, at the moment): Notice how the RAM sort of falls off a cliff…

  
  

• Perform Rolling Upgrade of Web Farm using Windows Network Load Balancer

  

  Date Published: 07 September 2010

  Once you’ve set up a web farm / cluster using Windows Network Load Balancing, one of the benefits you have is the ability to perform a rolling upgrade. A rolling upgrade is a process by which you perform updates to individual servers within the cluster while they are not actively serving requests. This process is repeated so that eventually all servers have been updated, but users have not…

  
  

• Applying Interface Segregation to Configuration Files

  

  Date Published: 31 August 2010

  In .NET, it’s very easy to set up custom configuration section handlers to handle your application or component’s configuration needs. As my previous post shows, it’s also very easy to configure these with attributes that enforce required fields and other validation. However, over time it’s very easy to create fairly large configuration sections that violate the Interface Segregation Principle…

  
  

• System.Core in VS2010 Projects

  

  Date Published: 24 August 2010

  I just ran into an odd issue with a VS2010 project. In my case it was an MVC 2 application I was upgrading from VS2008. One of the built-in controllers (ProfileController) was failing to compile because it could not resolve the Linq extension method symbols Single() and Matches(). These are located in the System.Core assembly. I checked my project references in Solution Explorer, and System.Core…

  
  

• Using CCTray with JetBrains TeamCity

  

  Date Published: 23 August 2010

  TeamCity is a great build server tool from JetBrains (makers of the awesome Visual Studio add-in, ReSharper). The user-interface and features of the TeamCity web front-end are wonderful and are leaps and bounds easier to use for new users than my previous favorite, CruiseControl.Net, which required much XMLness to configure. However, one of my favorite tools from CruiseControl, CCTray, still has…

• Set Up Build Agents By Project in TeamCity

  

  Date Published: 06 July 2010

  We’re using TeamCity to manage our continous integration builds for CodeProject.com and LakeQuincy.com. Before TeamCity, I was using CruiseControl.net, and TeamCity is much easier to get working (and requires far less XML manipulation). I do miss CCTray, which I found to be much nicer than the TeamCity tray notifier (which if you click on it never shows anything immediately – it has to go and get…

  
  

• How Can I Determine The Current Controller or Action in an Html Helper

  

  Date Published: 02 July 2010

  If you’re writing an HTML Helper for ASP.NET MVC you may want to do something different based on whether the page that is to be rendered was arrived at via a particular controller or controller action. I found the following code which does just this in one of the ASP.NET MVC Themes available from the www.asp.net web site (the Dark theme, I believe it’s called).

• Budding Versus Festering Code

  Date Published: 28 June 2010

  This is in response to Michael Feathers’ recent post on Festering Code Bases and Budding Code Bases. Certainly the default tooling in the Visual Studio space has, until recently, made it dramatically easier to add code to an existing class than to create a new class. However, tools like ReSharper have a large impact on this, and can make it extremely easy to create new classes, put them in their…

  
  

• Tagging Releases in Source Control

  

  Date Published: 22 June 2010

  A best practice when you're using source control is to tag your releases. What does this mean, exactly? If you're following the relatively standard non-distributed source control repository folder structure of having root folders for: branches tags trunk then it means simply making a copy of the current state of the system when you did your release. Here's how to do it using Subversion (SVN) and…

  
  

• Great Uses of Using Statement in C#

  

  Date Published: 18 June 2010

  In my last post about testing emails in .NET, I noted the use of the using statement to ensure safe usage of the IDisposable SmtpClient and MailMessage objects. This is the typical usage of the using statement, but you can take advantage of this statement’s behavior for other scenarios as well, resulting in cleaner code. Consider the scenario where you want to perform some kind of pre- and post…

  Recently I learned a couple of interesting things related to sending emails. One doesn't relate to .NET at all, so if you're a developer and you want to easily be able to test whether or not emails are working correctly in your application without actually sending them and/or installing a real SMTP server on your machine, pay attention. You can grab the smtp4dev application from codeplex, which…

  
  

• Dont Throw Duplicate Exceptions

  

  Date Published: 17 May 2010

  In your code, you’ll sometimes have write code that validates input using a variety of checks. Assuming you haven’t embraced AOP and done everything with attributes, it’s likely that your defensive coding is going to look something like this: Do you see a problem here? Here’s the deal – Exceptions should be meaningful. They have value at a number of levels: In the code, throwing an exception lets…

• Detect Unicode Usage in SQL Column and Optimize Storage

  

  Date Published: 28 April 2010

  Last Updated: May 2024 One optimization you can make to a SQL table that is overly large is to change from nvarchar (or nchar) to varchar (or char). Doing so will cut the size used by the data in half, from 2 bytes per character (+ 2 bytes of overhead for varchar) to only 1 byte per character. However, you will lose the ability to store Unicode characters, such as those used by many non-English…

• Adding Attributes to Generated Classes

  

  Date Published: 16 April 2010

  ASP.NET MVC 2 adds support for data annotations, implemented via attributes on your model classes. Depending on your design, you may be using an OR/M tool like Entity Framework or LINQ-to-SQL to generate your entity classes, and you may further be using these entities directly as your Model. This is fairly common, and alleviates the need to do mapping between POCO domain objects and such entities…

  
  

• Fix: Cant Change or Remove Visual Studio 2008 from DVD

  

  Date Published: 08 March 2010

  If you installed Visual Studio 2008 on a 64-bit operating system, you may have trouble when you try ad add or remove functionality by inserting the disk (or remounting the ISO image). I believe this is because of the path used to install the 32-bit Visual Studio program.

  Occasionally I find myself wanting to SELECT from a SPROC in SQL Server. Usually this is because I want to ORDER the results or filter them further with a WHERE clause. Unfortunately, you can’t just do this: There are several workarounds here, and the appropriate one depends mostly on whether you have any control over the use of the stored procedure, or how it works. For example, you could choose…

  A couple of days ago I was annoyed that Resharper was insisting on turning my abstract base NUnit test class with nothing in it but a shared [SetUp] method into a one line class with a collapsed Setup / Teardown region in it. While I didn't always feel this way, my experience has taught me that regions are a smell in your code. They are a way to hide things you don't want to deal with or look at…

The video quality is pretty nice, too, though I’m sure it’s well below whatever the native quality…

  
  

• IDisposable and WCF

  

  Date Published: 09 February 2009

  Recently we’ve been separating our monolithic application into smaller systems which communicate via services. We’re using WCF for this communication, and one of the things that we’ve quickly noticed is that WCF is, for whatever reason, not compatible with the usual best practice of wrapping IDisposable objects with a using() {…} block. Personally, I don’t think resources should be marked…

  
  

• CodeMash 2009 Aftermash

  Date Published: 12 January 2009

  CodeMash 2009, the third annual Ohio conference (and as far as I know, the largest Ohio developers’ conference), was by all accounts a great success last week. I was privileged to be a speaker at the show but also got a lot of value out of the networking opportunities and other sessions. Mary Poppendieck was also speaking, and it was great to get the opportunity to meet her and her husband Tom, as…

  
  

• Head First Design Patterns

  

  Date Published: 05 December 2008

  I picked up Head First Design Patterns a couple of months ago and read it last month. I have to say that this book is totally different from any other software development book I’ve read in the past. Most software books, you probably know, follow a fairly predictable pattern with each chapter covering some piece of technology through large amounts of text interspersed with code blocks and…

This was my first time presenting on ASP.NET MVC and I want to definitely thank ScottGu,ScottHa,Phil Haack, and Jason Gaylord for their great presentations on this subject, from which I borrowed and added…

  
  

• Programming is Just Typing

  

  Date Published: 18 November 2008

  Well, OK, it's not just typing, but fundamentally, typing has a lot to do with it. In fact, it wouldn't be too great a stretch of the imagination for someone watching a room full of programmers to mistake them for a room full of writers, typists, dictation takers, or similar clerical staff. What we do to produce software is type it in, one word at a time. Jeff Atwood writes We Are Typists First…

  In my session this week on Membership and Personalization in ASP.NET, I mentioned a commercial control for this but couldn’t recall the name or URL. Well, here it is, the ASP.NET Membership Management control from Quality Data. I have not personally used the control, but it looks like it has all the features one would need. It’s currently $59 per web server, which seems pretty reasonable.

In preparation for a talk I’m giving this week at DevConnections, I went out to grab the source again to be able to show it off during my talk. But no matter where I told it to install, nothing was installed. By default it wanted to go to C:Program…

  
  

• Azure Deployment Portal – Use IE

  

  Date Published: 30 October 2008

  Ran into a small bug in the Azure deployment portal today using Firefox. The “swap” button to swap out a staging with a production environment was non-responsive. Switched to IE and it popped up an “are you sure” alert box as expected. I’m sure this will be addressed quickly but if you’re trying out Azure you may want to be aware of the issue.

  
  

• Check if Unique Constraint will be violated before Insert with LLBLGen

  

  Date Published: 30 October 2008

  I needed to determine if a unique constraint would be violated so that I could programmatically update the Name of a business object to make it unique today. I use LLBLGen for this project’s database layer, and I have a unique constraint (actually a unique index) set on the database. In this case it covers two columns, an integer ID and a string Name, but the nice thing about LLBLGen is that it…

  A common area to test in software are ranges of values and off-by-one errors. But this problem certainly isn't limited to programmer code. I just wrapped up a survey by TNS for customer satisfaction that ended with this question. Note that I have 10 employees in my company (trying to pick the invisible radio button between the first and second one didn't work). [range error example

• Reducing SQL Lookup Tables and Function Properties in NHibernate

  

  Date Published: 05 October 2008

  One of the points made in Jeffrey’sagile development boot camp last week that struck a chord with me was that many database-centric designs have lookup tables that aren’t really just data. That is, tables that hold values such as statuses that, if modified, can easily break existing code or won’t function as expected without the addition of code. We have a lot of these in our codebase, and we’ve…

  I have a copy of Murach’s ASP.NET 3.5 Web Programming with VB 2008(book web site) that I received over the summer and have been meaning to write a short review. So here goes.

  I gave a one day class to about 20 developers today introducing Microsoft .NET, C#, and ASP.NET. As it was only one day and there were no hands-on labs, coverage was necessarily cursory, but overall things went very well. In the course of discussing the Base Class Library and specifically the areas of logging and sending emails (System.Diagnostics and System.Net), I was careful to emphasize to the…

  
  

• Codebehind Files in ASP.NET MVC are Evil

  Date Published: 17 September 2008

  With the current versions of ASP.NET MVC (Preview 5) that have shipped, the default MVC template sites all include codebehind files for the ASP.NET views. For example, here’s a screenshot of what a new project looks like the one at right. Further, adding a new ASP.NET MVC View Page will also include a .aspx.cs and a .aspx.designer.cs file by default. The question is, why is that codebehind file…

• Client Side Client Detection

  

  Date Published: 10 September 2008

  I just heard about a new flavor of the top of the line client detection component, BrowserHawk, that is being branded as “BrowserHawk To-Go (BHTG).” What’s interesting about this (to me) is that it’s following a SaaS model and a pay-as-you-go scheme for pricing. This makes the software very affordable for startup sites and simplifies the installation requirements. Implementation in this case is…

  Date Published: 08 August 2008

  Anybody who’s talked to me about web programming in the last 5 years or so knows that I’m a big fan of caching. However, in most of my presentations on ASP.NET caching, I don’t get into the client side of things. Mainly this is because ASP.NET is a server-side technology and there’s plenty of cool stuff to talk about on the server with regard to caching, and I truly think that’s where the biggest…

  Since .NET 1.0, there has been a built-in appSettings section in configuration files. Many developers use this space to store application settings, such as the name of the site or (before ) database connection information. However, many third party tools also make use of this collection, which is a bad practice. Third party tools should use their own configuration section, which is incredibly easy…

  I’m a big fan of ASP.NET AJAX in general, but one concern I have and something that has forced me to use other technologies is the size of the library.

  Date Published: 10 September 2007

  I've recently been experimenting with other fonts for Visual Studio on Vista after reading this article on new fonts in Vista. I think I like Consolas better than Courier New for coding, if only for its novelty. It also tends to be a little bit more compact than Courier New at the same font size, which is nice to keep long lines from wrapping. Have a look at the difference, see what you think…

  
  

• Accessing Session from an HttpHandler

  

  Date Published: 29 July 2007

  I’ve run into this before but forgotten about it. I wrote an HttpHandler recently and was trying to access the Session object from the passed in HttpContext context object with context.Session[“foo”] = “bar”; and I encountered a NullReferenceException. Some searching quickly yielded the answer, which is that in order to access Session from an HttpHandler you need to add a marker interface (meaning…

• Beyond Good Enough Is Waste

  Date Published: 27 June 2007

  I just finished reading Jon Galloway’s post, The value of “good enough” technology, and it reminded me of something I repeat very often in my talks on improving performance and/or caching (which share some content as you may imagine).

• Coding Optimization Tip: Avoid Repeated FindControl() Use

  Date Published: 27 January 2007

  In a project I’m working on I have a recursive FindControl() which is quite useful for finding controls that are hiding inside of templates like LoginView or CreateUserWizard. I’m working with some junior developers and trying to instill best practices into them. This is an example of a code optimization technique I’m applying today to some code one of them wrote.

• CodeFile or CodeBehind

  Date Published: 24 January 2007

  I just fixed a problem on a coworker’s machine that was quite odd in that the fix involved simply changing CodeFile to CodeBehind in a user control (.ascx) file. The issue was that in the ASPX page I was doing a FindControl within a Repeater’s ItemDataBound event, and casting the resulting control to the type of the codebehind of the user control. So for example if the user control was foo.ascx…

One advantage he noted is that as we start to move more and more toward multi-core computers, rather than faster and faster single cores, the need for applications to be partitionable over multiple processors will…

• Atlas Charting Goodness

  

  Date Published: 05 June 2006

  I really love charts and statistics. Give me a decent reporting application and I can spend all kinds of time analyzing data this way and that, looking for trends. The problem is, usually you have to have a separate reporting interface, away from your main application, which limits its usability. One reason for this is that charts take up a lot of room, and so you don’t want to detract from your…

  Overview Validation controls have been one of my favorite features of ASP.NET since I first saw it previewed (back when it was still ASP+). Coming from an ASP background, where integration of client- and server-side validation was, to be kind, tedious, I was eager to put these controls to the test. Initially, I was very pleased with the controls, but with time it became clear that they were "a…

• Caching: Automatically Renew Stale Items

  

  Date Published: 16 June 2005

  I’m working on a new library for Caching that has been an interest of mine for some time, but which I only took the time to implement last week (on the plane home from Charleston). Basically the problem is that for many of the things that are ideal candidates for caching, it would be nice if there were an easy way to keep these in the cache forever while still ensuring the cached values are…

Abstract: The typical use of caching applies to read caching, or caching data in the application…

It worked out of the box, and claims to be compatible with NUnit 2.1 and…

• Making DataReaders Less Evil

  

  Date Published: 17 September 2004

  I admit it, I’ve never been a big fan of the DataReader. There are two main reasons for this. Firstly, I’m a big fan of caching, and DataReaders cannot be cached. Thus, even if they are, say, 2x as fast as a DataTable the first time, the cached DataTable is 10x faster whenever it’s read from the cached (these numbers are made up just like 87% of all statistics). Another reason I’ve shied away from…

  In case you’ve been in Iraq or something and haven’t already seen this, here’s a post from Shankuabout upcoming changes to ASP.NET coming in Beta 2 (mostly features that won’t make the cut). http://weblogs.asp.net/ShankuN/archive/2004/08/16/215487.aspx Somehow, despite my being in Iraq at the moment, this blog still gets way more readers than my current one at ArmySteve.com. I guess that’s a good…

  Date Published: 14 June 2004

  If you’re someone who’s interested in some content on a particular site, especially a blog, and you find yourself constantly checking the site to see if any new information has been posted, then you probably would benefit from using an aggregator. Almost every blog engine supports a standard called RSS, which is the de facto aggregation standard. What RSS does is provide a standard format…

• 3DFTP Client >> WS_FTP(lite) Client

  

  Date Published: 08 June 2004

  I’ve been using WS_FTP for a LONG time (the free/lite version) and recently I had the need to download something with resume capability (my ‘net access is intermittent at best here at Ft. Leonardwood, Missouri). So I did a quick search and found 3dFTP, which I downloaded and have been very happy with. It’s multi-threaded, so it will download several files concurrently. Somehow, that makes for a…

  
  

• Micro Caching Article Published

  

  Date Published: 04 May 2004

  Those of you interested in caching should read my article on AspAlliance about what I’ve termed micro-caching. Basically, the idea is that even a very short-term cache can make a big difference in site performance for a high-volume application or resource. I’d known about this in theory for some time, but I finally demo’d it to a class I was teaching at Ohio Savings Bank in April to get some hard…

  
  

• ASP.NET Micro Caching - Benefits of a One-Second Cache

  

  Date Published: 03 May 2004

  Introduction I fell in love with caching when I first started playing with it in the early versions of the ASP.NET alphas. I was aware of caching before that, but I'd never really gone to the effort to seriously implement a cache engine in an ASP app, and with ASP.NET, I didn't have to. The thing that attracts me to caching is its impact on performance without requirements (usually) for major re…

  
  

• Properties? Universally good or not?

  

  Date Published: 29 April 2004

  jaybaz_MS writes about Properties? Not my bag baby and makes some excellent points. I’m at a public connection right now so I don’t have time to take up his challenge of writing a generic cached property class, but perhaps when I have some time at home I will (and this post will remind me).

I’ve uploaded the first couple of days’ pictures to a gallery here. Update: David Gottlieb has some more pictures here. I’ll be adding more to my gallery, perhaps today, as well.

  
  

• ASP.NET Feature Request

  

  Date Published: 10 April 2004

  If you’re not aware, a great feature coming in ASP.NET 2.0 allows user profile data to be stored based on a simple config section, with strong typing and design time Intellisense. Thus, you can modify the pieces of information you wish to store about a user, and immediately get Intellisense, strong typing, etc. However, the Roles feature continues to use string literals to describe roles, such as…

  
  

• More Breaking Changes for Whidbey – Personalization/Profile

  

  Date Published: 04 April 2004

  Personalization as a keyword/namespace has been replaced with Profile. The namespace, the config section, etc. Also, the provider model for personalization has changed between the PDC Whidbey and the March04Preview Whidbey, such that now providers must inherit from System.Web.Profile.ProfileProvider, rather than implementing a couple of (now non-existent) interfaces. An example config section…

  I’m presenting two ‘Meet the Technologist’ Sessions at TechEd04. These sessions are similar to breakout sessions and run at the same time as the breakouts and for the same length of time. The only difference is they are smaller and more intimate, with the largest ones seating about 40 people. They are located in the Developer Tools and Technology community area. The first one I’m presenting is on…

This is a feature I’ve had an interest in for some time, but I want to take it a step further. I’ve mentioned this on several occasions to members of the VS.NET team, but I don’t think they’re going for it, so please comment on…

  Scott Cate, who runs kbAlertz.com, among other things, writes about an intermittent error he was getting on his site last fall. Shortly before this, I had written an article on msdn about Caching Best Practices, in which I described a caching pattern that should be followed to ensure proper behavior (e.g. no null reference exceptions). Scott was getting intermittent errors about 1 every 50,00…

• Avoiding the Global Assembly Cache

  

  Date Published: 29 March 2004

  Chris Sells writes about reasons why we should avoid using the Global Assembly Cache, or GAC (pronounced “gack!”). I have to say that I definitely agree with his sentiments. Ted Neward disagrees with some points here. One counter-argument Ted makes against Chris’ original statement is this: First and foremost, I’ve never heard of the idea that the GAC is there to save hard drive space; anybody who…

• ASP.NET Whidbey Overview

  

  Date Published: 29 March 2004

  Introduction ASP.NET was first previewed at PDC in July of 2000. The first beta followed about a year later and the actual RTM of ASP.NET 1.0 came in February of 2002. ASP.NET 1.1 and Visual Studio 2003 came about a year after that, but did not include many feature updates. ASP.NET 2.0 / Visual Studio 2005, collectively code-named 'Whidbey', have been in development since before ASP.NET 1.0 was…

  
  

• Mounting ISO Images as Drives

  

  Date Published: 28 March 2004

  I tried using Isobuster to extract the ISO of the VS2005 DVD image that I just downloaded off of MSDN but after burning it, I got a “Please insert VS Disk 1” midway through the install (I don’t know if that was user error, an Isobuster issue, or a DVD-burning issue — probly user error). So, that DVD is now a coaster. Did a quick search since I knew that it should be possible to mount an ISO as a…

  I’ve been looking for some ad serving software for DevAdvice this year, and the best one around for purchase that I’ve found is deloittes.NET AdServe. I have their full-source license, which comes with VB and has thus far been pretty easy to customize with a few of my own requirements.

  As I mentioned in an earlier post, I’ve just installed VS 2005 and am now ready to start reporting on it. Some folks like Rick have reported stability issues with this build but I haven’t had any such problems thus far, and it is working much better than an interim build I had installed about a month ago. One of the first things I’m doing is looking for breaking changes from the previous alpha, of…

  
  

• More Breaking Changes in ASP.NET (March 2004 Preview Build)

  

  Date Published: 28 March 2004

  Found some more breaking changes: System.Web.Personalization no longer exists. I believe it’s been renamed to System.Web.Profile but I haven’t 100% confirmed this yet. System.Configuration.Settings no longer exists. I can’t find its replacement. I’m looking for where IProvider and ISettingsProvider are defined now. I can’t find these either, so I’m thinking they may no longer exist. I’m not sure…

There were over 200 people there. I saw a bunch of folks I’ve worked with before at various clients in the Cleveland area, including Gregg, John, Mike, Dan, and others.

  Xander Sherry has a new blog and is wondering why people like Vault. Here’s my $.03. It’s all .NET. I know that shouldn’t really matter to me as long as it does what it says it does, but i like that. It’s DB-based, so it won’t get corrupted or have issues with file locks like VSS does. It works over the Internet – VSS doesn’t. It’s alive and thriving. VSS has been on 6.0x for the last decade…

  
  

• InfoPath 2003 Hacking Change XSN Location; DB Source

  

  Date Published: 26 February 2004

  I built a handy InfoPath form to do some data entry for the AspAlliance Ad Network back when it was still in beta over the summer of 2003. In December, I moved my database server to a dedicated box (with new connection string settings), and around that same time I rebuilt my file server and renamed it as well. Thus, the next time I went to use my handy InfoPath form, it informed me that the XSN…

  Date Published: 25 February 2004

  Check it out — the InfoPath 2003 Toolkit for VS.NET was released a few days ago. My biggest gripe about InfoPath is that it relies on VBScript/JavaScript and ADO for its customization (e.g. anything outside the norm you want it to do). Well, according to the download page, the new toolkit: provides integration features and documentation that enable you to use Visual Studio .NET to create, debug…

  Date Published: 14 February 2004

  As I posted here, I’m interested in a feature of the ASP.NET Cache engine that isn’t there today, and it sounds like won’t be there in Whidbey. To wit, I’d like to be able to throw something in the cache and have it periodically update itself in an offline process, rather than simply expire and force a user request to sit and wait while the data is retrieved. I’ve come up with a workaround/hack…

• PDC ASP.NET Panel Discussion – Non-Postback Callbacks to Pages

  

  Date Published: 29 October 2003

  A new feature in Whidbey will allow controls to make calls directly back to page methods without making full postbacks. This features uses XMLHTTP behind the scenes and allows controls to talk to the server in an optimized fashion without requiring a full postback. In the 1.x timeframe, a solution for this which you can use today (and which actually may be simpler to implement based on what I’ve…

  Date Published: 27 October 2003

  Managed to get to some sessions today, including the morning’s keynote, which was lucky since I was out pretty late with a bunch of Codewise community members and Microsofties. The keynote was pretty cool, and included an excellent demo by Scott Guthrie as well as a fun demo of mobile control support by Batman. I spent most of the middle of the day in the expo hall talking to various vendors about…

  Introduction - What is Vault? SourceGear Vault (Version 1.2.2 as of this writing) is a version control system for Windows developers. If you've used Visual SourceSafe, Vault is a similar (but much better) product. It is built entirely on the .NET Framework with a SQL Server 2000 backend storage system (as compared to VSS's file system storage system). A key feature of Vault is its backward…

  Date Published: 27 October 2003

  Caching in 1.x... ASP.NET Caching in 1.x is very powerful and includes three pieces: output caching, fragment caching, and the cache API. The simplest form, output caching, simply caches the output of a page. Fragment caching is a bit more granular, and caches the output of a user control. Finally, the most powerful caching functionality is achieved using the cache API, and allows any…

• Enums and Lookup Tables

  

  Date Published: 22 September 2003

  Everyone knows (or would know if they’d read Code Complete) that ‘magic numbers’ are a bad thing in your code. Enumerated types, or Enums in .NET, are a great way to avoid such magic numbers. For instance, let’s say I have a content management system which has articles whose state can vary between Draft, Editing, and Production. I could simply use 1, 2, and 3 for these states and remember what…

• The Caching Pattern

  

  Date Published: 20 June 2003

  Here’s a little something that I term “the caching pattern” for using the ASP.NET cache object: The as keyword will try to cast Cache[key] to DataTable and if unsuccessful it will return null. If it is null, it will return null. The rest of it is pretty straightforward. This is the best practice way to get something from the cache, but look at it! It’s huge!
