    This works:

    Code:
    DEVMODE screen;
    screen.dmBitsPerPel = 32;
    screen.dmPelsWidth  = WIDTH;
    screen.dmPelsHeight = HEIGHT;
    screen.dmFields     = DM_BITSPERPEL | DM_PELSWIDTH | DM_PELSHEIGHT;
    
    if(ChangeDisplaySettings(&screen, CDS_FULLSCREEN) != DISP_CHANGE_SUCCESSFUL) {
        // Fullscreen failed
        return 0;
    }
    Position your window at (0, 0) and make it WIDTH wide and HEIGHT high so it covers the entire screen.

    I changed it to this:


    Code:
    DEVMODE screen;
    screen.dmBitsPerPel = 32;
    screen.dmPelsWidth  = GetSystemMetrics(SM_CYSCREEN);
    screen.dmPelsHeight = GetSystemMetrics(SM_CXSCREEN);
    screen.dmFields     = DM_BITSPERPEL | DM_PELSWIDTH | DM_PELSHEIGHT;
    
    if(ChangeDisplaySettings(&screen, CDS_FULLSCREEN) != DISP_CHANGE_SUCCESSFUL) {
        // Fullscreen failed
        return 0;
    }
    But it failed! How come?

    If all you need to do is set your window dimensions to the same as your current desktop then just use GetSystemMetrics to get the desktop width and height and use these to create your window (or use SetWindowPos or MoveWindow after window creation).

    If you are using ChangeDisplaySettings then its probably best to use EnumDisplaySettings first to fill out a viable DEVMODE struct for your target machine.

    You've switched width and height values.

    I don't get it I swiched the width and height values, now it goes fullscreen black. Then t goes back to a window.
    I am getting confused. So could you just tell me how to get rid of the title bar on a window?

    I just tried Ken's solution and that works just as fine (or better, since you need less code), so you don't need to use ChangeDisplaySettings. Just use WS_POPUP as your window style, and set the width and height of your window to the width and height of the screen:

    Code:
    HWND window = CreateWindow(
                            TEXT("Class"),
                            NULL, // WS_POPUP has no title bar
                            WS_POPUP, // No title bar or border
                            0, 0, // Position the window at the topleft
                            GetSystemMetrics(SM_CXSCREEN), GetSystemMetrics(SM_CYSCREEN),
                            NULL,
                            NULL,
                            hInstance,
                            NULL);
