Creating an MCIWnd Window

[The feature associated with this page, MCIWnd Window Class, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of MCIWnd Window Class, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The MCIWndCreate function registers and creates an MCIWnd window. The window can be a parent, child, or pop-up window. The following example creates an MCIWnd window as a child window and lets the user control playback by providing access to the trackbar and the Play, Stop, and Menu buttons. The example specifies a handle of a parent window and specifies NULL for the window styles, so the default window styles of WS_CHILD, WS_BORDER, and WS_VISIBLE are used to create the MCIWnd window.

// Global variable and constants 
// extern HINSTANCE g_hinst;       instance handle 
// extern HWND g_hwndMCIWnd;       MCIWnd window handle 
 
case WM_COMMAND: 
    switch (wParam) { 
    case IDM_CREATEMCIWND: 
        g_hwndMCIWnd = MCIWndCreate(hwnd, g_hinst, NULL, 
            "sample.avi"); 
        break;    
    } 
    break;
