Winform stick to the desktop and only desktop

Question

How can I make my WinForm stick to the Desktop and only desktop? The effect is similiar like Active Desktop item or Desktop calendar. Can someone help me in this context? thank you.

I want to do the same but also havn't got any Solution yet. However I was able to determine which Message I get when the Show Desktop (which is my biggest problem to keep my form visible on the desktop) command is executed: VM_ACTIVATEAPP (from the Messagehandler WndProc) WParam and LParam tells me that my Form is deactivated and a Thread of the Explorer.exe Process has been activated. So the only problem now is how to determine if the Thread which is beeing activated really is the Desktop Thread (the explorer Process has a bunch of different threads). (Keeping the Form visible is possible by Setting the Forms TopMost Property for a short time - not really a good way to handle this but at least it works)
