I would like the create a program that displays current CPU usage as
part of the background image. The only way I could think of doing this
was by using GetDesktopWindow and drawing on that, but nothing appears
when I draw, and I would think that I might end up drawing over other
windows since they are all children of the desktop window. I'm at a
complete loss as to how to do this. Does anyone have any suggestions?

I'm using pure WinAPI, not the MFC.

You can use DDraw and Overlay surface
or create a window as child of the Desktop
or subclass the Listview, etc...

Well, since all windows are children of the desktop automatically,
doing the second option isn't hard. I'm thinking that I should make
either a full-screen window, somehow keep it behind everything else,
and somehow draw it behind the taskbar, OR I could create a regular
window and do the same thing, but just position it so that you don't
see the window borders. Any ideas on how to do that?
