Most restrictions and tricks with windows forms are common to most programmers. But since .NET 3.0 there is also WPF available, the Windows Presentation Foundation. It is said that you can make "sexy applications" more easy with it and with .NET 3.5 SP1 it got a good speed boost on execution. But on the other side a lot of things are wo...

I've got a menu that contains, among other things, some most-recently-used file paths. The paths to these files can be long, so the text sometimes gets clipped like "C:\Progra...\foo.txt" I'd like to pop a tooltip with the full path when the user hovers over the item, but this doesn't seem possible with the Tooltip class in .NET 2.0. ...

What I want is to be able to catch all exceptions from events behind GUI elements (e.g. button_Click, etc.). I then want to filter these exceptions on 'fatality', e.g. with some types of Exceptions...
This question is slightly related to this question about exception handling. The workaround I found there consists of rolling my own message loop. So my Main method now looks basically like this: [STAThread] static void Main() { // this is needed so there'll actually an exception be thrown by // Application.Run/Application.DoEvents...
I'm making an example for someone who hasn't yet realized that controls like ListBox don't have to contain strings; he had been storing formatted strings and jumping through complicated parsing hoops to get the data back out of the ListBox and I'd like to show him there's a better way. I noticed that if I have an object stored in the Li...

The command being executed was "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727...
