Get thumbnail image of the main page of all the running process in window

Question

In my app I want to enable the user to see a small thumbnail, of the main window, for all the running process (that has window).

• My app is a regular window desktop application (written in wpf)
• I don't want to bring the other processes to foreground before getting the thumbnails
• It will be nice if most of the code will be written in .net with PInvoke (if needed) but native is o.k also

Thanks

Answer 1

using DWM I managed to capture the main window for all running process. I've used two great examples (thank a lot for that).
