Not that you're asking, but this is simple to do with WPF.

Here's a quick straight WPF sample. I just grabbed the About dialog for a UI automation tool that I'm working on and put it into a new WPF application.

The screenshot is the app running on my Windows 7 desktop.

You can adjust the Opacity property in the Window1.xaml to alter the transparency.

The screenshot looks nice but I can't open the project for some reason. I'm using VC++ 2008 EE on Windows XP. It says my version of VC++ doesn't support the project type (.csproj). No C/C++ files either? Sorry I'm a bit of a VS noob.

Sorry, I wasn't clear about WPF. WPF is only supported in C# and VB.Net.
