I am starting to believe that you can do nothing with Windows API.

I have two windows. One has a DWM thumbnail in it. What I want to do is, I want to be able to capture the screen of the window with the thumbnail into the other one. When I do this, using bitblt, everything is copied except the thumbnail. It just isn't there in the bitmap.

So how does the DWM rendering work? I mean, if DWM renders thumbnails directly onto the DC of the registered window, then my approach should work. I'm confused.

Thanks a bunch.
