There are some very interesting posts I missed the last days. Since .NET 3.5 SP1 perfectly integrates WPF with DirectX, a number of cool effects can finally be applied:

Some of those effects were on Dax Pandhi’s wish list for WPF (http://blog.nukeation.com/post/My-wishlist-for-the-next-release-of-WPF.aspx) for quite some time.
More importantly, the integration of WPF and Direct3D might eliminate the [...]
Have you ever tried to call ICommand.CanExecute()? It actually works fine, but only if you are not as naive as I am… Simply calling it without the proper know-how might result in a NullReferenceException, so what you should read is how to implement ICommandSource. See
MSDN: How To: Implement ICommandSource
MSDN: Implement ICommandSource Sample.
Not a big thing, [...]
Today, I encountered two WPF related problems:
1 – UIElement.Opacity and the way it is being ‘inherited’
Every UIElement has an Opacity property, which will we be used when rendering the control. When rendering an object, 0.0 means the object is fully transparent, thereby invisible to the user, while 1.0 means it is fully opaque. Since controls [...]
In the MenuKiller Control, I need to configure a TreeView to quite some extent: I want all nodes to have a certain custom ItemContainerStyle.
First naive approach: The TreeView will apply its ItemContainerStyle to all nodes. Wrong! The TreeViewItems themselves are ItemControls, therefore having their own ItemContainerStyle.
Second approach: Have the ItemContainerStyle refer to itself using [...]
A while ago, I read a very interesting blog post: Rethinking the Button by Dax Pandhi. It really fascianated me, so I started some research on the topic. Apparently, “Differentiated UX” is the new buzzword. As is always the case with buzzwords, different people understand it in different way, but I guess the common denominator is: We [...]
While implementing a little custom control (a radial panel, actually – stay tuned what it’s good for…), I stumbled across a little problem when trying to add automatic behaviour.
Many built-in WPF Controls such as Canvas or Panel allow something like
Width="Auto"
Now, for my control I need something that accepts
AngleSpacing="Auto"
AngleSpacing="<double>"
Of course, accomplishing that is very simple, but [...]
Huge thanks to Ilmar Kruis for implementing GetDeviceCaps() in the Tao framework! With some small modifications I suggested, one can now easily develop DPI-aware OpenGL applications using C# or .NET in general! Thanks Ilmar!
I will update my article on the CodeProject about OpenGL windows in Vista soon!

Hello, World!
Ok, my first blog entry! I also posted my first article at The CodeProject today:
