    DOS fullscreen

    I would like to put my DOS programs into fullscreen using some sort of code (in MS Visual C++ 6.0 standard). On windows 98 you can press a button on the DOS console to make it fullscreen, but you can't in XP. And beside the point, I want to make my programs fullscreen without the user having to do anything, so some sort of code would be nice. (wow, that was redundant)

    You can try a trick like this:
    Code:
    #include <windows.h>
    
    void
    fullscreen()
    {
      keybd_event(VK_MENU, 0x38, 0, 0);
      keybd_event(VK_RETURN, 0x1c, 0, 0);
      keybd_event(VK_RETURN, 0x1c, KEYEVENTF_KEYUP, 0);
      keybd_event(VK_MENU, 0x38, KEYEVENTF_KEYUP, 0);
    }
    It simulates Alt+Enter to bring an application into full screen mode.
    My best code is written with the delete key.
