Redirect graphical output of a window?

[Fox]

Hi everyone.

How can I change the canvas/DC of another application? What I want to do is take eg. Notepad.exe and capture the window so that it's not drawn on the desktop but in a graphic buffer I created.

Like changeing the rendering device for a window, know what I mean? The goal is to render another application directly into a directX texture instead of copying the window contents 30 times a second.

Thanks for help,
