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);
}
