Hi,

is it somehow possible to readout the content of another window (i have its handle) and draw it on my bm screen?

For example ist it possible to read out the content of the desktop and past it into my window?

Ok, if i get the regio of the other window and the data in it. How can i transfer this graphic into an image or something similar, so i can paste it into the backbuffer of my application and do a flip to show it.
