I'm using several windows in a DirectDraw (7) program, and I want to render to both. Currently, I can only render to one. If I try to render to the other, the clipper will prevent that or the graphics is incrediblt flickery.
What I do is simply getting the rect of the other window and render to it, but I guess the stuff is actually drawn on the first window.
How do you render to several windows in the same program? Do you need two DirectDraw objects, one for each window?
