Foreground Applications

Is there a way to NOT make an application become foreground?
But still be able to get user input?
Like maybe, whenever my program is foreground,
make Desktop become foreground?

Yeah, SetWindowPos with the HWND_BOTTOM parameter does that. He probably would want to hide the window instead though, using ShowWindow.

Keystroke capture can be done using SetWindowsHookEx with WH_KEYBOARD.
