    /* Use Windows's default colour as the background of the window */
    wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;

    /* Register the window class, and if it fails quit the program */
    if (!RegisterClassEx (&wincl))
    return 0;

    );

    /* Make the window visible on the screen */
    ShowWindow (hwnd, nCmdShow);

    /* Run the message loop. It will run until GetMessage() returns 0 */
    while (GetMessage (&messages, NULL, 0, 0))
    {

    }

    {
    case WM_CREATE:
    mciSendString("open MUSIC\\PUG2.MID type sequencer alias music", NULL, 0, NULL);
    mciSendString("play music", NULL, 0, NULL);
    break;
    case MM_MCINOTIFY:

    break;

    case WM_DESTROY:
