Windows7 taskbar thumbnail without showing a window

Question

Is it possible to "mark" my program as active in the windows7 taskbar without actually showing a window and even provide a thumbnail picture? I worte a small program which displays the system battery as a deskband. Now in windows7 I'd like to display the battery in the thumbnail picture, and make the deskband optional.

Answer 1

Yes, it is possible. You need to make your window permanently minimized. You can provide anything for the window's thumbnail.
