    Main window position

    Do you use CW_USEDEFAULT? Or do you put your own values in it?

    You can put either value, it is up to you.

    Of course you can, but what do you prefer?

    I don't do too much straight GDI type stuff anymore, I mainly use DirectX. However when I do need to, I usually use CW_USEDEFAULT though.

    Just our of curiosity (and a little off topic), where did you learn to program in DirectX? My buddy and I are going to start doing that, and I'm looking for some promising docs on it...

    Pretty much just doing stuff on my own. They taught the basics at school but I had to learn some of the other components entirely on my own (i.e. Direct3D). I'm sure there are a lot of good tutorials out there...perhaps at

    www.flipcode.com
    www.gametutorials.com

    Are you going to be doing DirectDraw stuff? Basic 2D game or something? If you need some specific help or a sample of something I can give you some of my old source code if you want. Well if you want to talk further about DirectX send me a private message and I can answer your questions.

    A quick note about putting in your own values for positioning a window. Make sure that you do put some care into where you put your window. Most importantly, make sure it is on screen. HKEY_CURRENT_CONFIG\display\Setting has a key called Resolution. This is what I usually use when I want to put a window in the middle of someone's screen or something. Enjoy.

    An easier way to get the screen res is

    Code:
    hdc=GetDC(NULL);
    iWidth	=GetDeviceCaps(hdc,HORZRES);
    iHeight	=GetDeviceCaps(hdc,VERTRES);
    ReleaseDC(hdc);
    
    // or as a RECT
    hDesktop=GetDesktopWindow();
    GetWindowRect(hDesktop,&DesktopRect);
