Hello I've got a major problem using gamma control! I have a lot of samples that works just fine, but I'm trying to use gamma control in windowed mode (not full-screen mode). I have never seen a windowed mode application wich uses gamma control [directdraw7] I have a guess: it might not work, and then I'm screwed! Is there anyone who can to tell wether i'm wrong or not. If it's possible to use gamma control in windowed mode, then give me a sample or something. Thanks in advance

I don't think its going to work. If it does work it will really slow up the display. The display driver would have to change the correction (gamma) as it crosses the inner window boundary. Might be easier to correct the windowed part before. Or use some form of dual buffering where the images are created in different display buffers.
