Setting Up the Playback Window

The following example finds the dimensions needed to play an AVI file, creates a window corresponding to that size, and plays the file in the window by using the MCIAVI driver.

HWND hwnd;

MCI_DGV_RECT_PARMS mciRect;

// Get the movie dimensions with MCI_WHERE.

mciSendCommand(wDeviceID, MCI_WHERE, MCI_DGV_WHERE_SOURCE,

    (DWORD)(LPSTR)&mciRect);

// Create the playback window. Make it bigger for the border.

// Note that the right and bottom members of RECT structures in MCI

// are unusual; rc.right is set to the rectangle's width, and

// rc.bottom is set to the rectangle's height.

hwndMovie = CreateWindow("mywindow", "Playback",

    WS_CHILD|WS_BORDER, 0,0,

    mciRect.rc.right+(2*GetSystemMetric(SM_CXBORDER)),

    mciRect.rc.bottom+(2*GetSystemMetric(SM_CYBORDER)),

    hwndParent, hInstApp, NULL);

if (hwndMovie){ 

    // Window created OK; make it the playback window.

    MCI_DGV_WINDOW_PARMS mciWindow;

    mciWindow.hWnd = hwndMovie;

    mciSendCommand(wDeviceID, MCI_WINDOW, MCI_DGV_WINDOW_HWND,

        (DWORD)(LPSTR)&mciWindow);

}
