.NET Framework Targeting Error (.NET Framework Client Profile)
Two of my colleagues: Alon Nativ and Ziv Farjun have found an interesting, yet confusing, issue in Visual Studio 2010 and .NET Framework 4. They work on a .NET Framework 4 solution which includes few .NET Framework 4 projects. To test the project they created a Console Application project, added a reference to their other projects, used the appropriate namespace, and created a class that is defined in one of their projects. Everything is made by the (old) book. However, the project failed to build...
The Easiest Way to Add a Splash Screen to Your WPF Application
It has been a long time … WPF applications do not start immediately. When an application is being loaded, there’s a delay while the CLR initializes the .NET environment and then starts the application. Splash screens are typically used to notify the user that the application is in the process of loading. The easiest way to add a splash screen to your WPF application is to have Visual Studio 2008 SP1 or later and to follow these steps: 1. Add an image file to your project. (you can use the BMP, GIF...
Embedding and Communicating with the Macromedia Flash Player in WPF
Download Source Code and Binaries (MyBlogUserControls.zip) Embedding the Macromedia Flash Player ActiveX control is a relatively simple way to do the following: Add functionality, graphics, or animation to your WPF application. Extend the capabilities of your stand-alone Macromedia Flash application (such as adding file I/O capabilities to Macromedia Flash). Use existing flash resources in your WPF application (i.e. Use Banners in your WPF application) Before you decide to embed the Macromedia Flash...

WPF Localization Guidance
When you limit your product's availability to only one language, you limit your potential customer base to a fraction of our world’s 6.67 billion population . If you want your applications to reach a global audience, cost-effective localization of your product is one of the best and most economical ways to reach more customers. It is imperative to define a globalization strategy early in the development lifecycle, in order to more quickly accommodate demands for future product releases that can...
Hardware Acceleration in WPF
Recently I’ve been getting several questions on hardware acceleration. Some people are running performance profiling tools and noticing that although it indicates that their application is running in hardware, the application is still taxing the CPU. This may seem confusing, so I will try to give some background in this posting. History Windows developers have been using the same display technologies for more than 15 years. A standard Windows application relies on two well-worn parts of the Windows...
digiTweet – an Open Source WPF Desktop Twitter Client
I love Twitter. Like many users I have moved away from the website to a client application (Powerful software, combined with the cloud – sound familiar?). I used to tweet using TweetDeck and twhirl which can be loaded on every PC, Mac or Ubuntu machine. However, being a .NET and WPF guy, there are a few things that bug me about most Twitter clients. Most of the Twitter clients run in AIR , being a great cross-platform (I use Windows only) light-weight (not so light) applications. I’m sure the amazing...
