realize

The realize command instructs a device to select and realize its palette into the display context of the displayed window. Digital-video devices recognize this command.

To send this command, call the mciSendString function with the lpszCommand parameter set as follows.

_stprintf_s(
  lpszCommand, 
  TEXT("realize %s %s %s"), 
  lpszDeviceID, 
  lpszPalette, 
  lpszFlags
); 

Parameters

lpszDeviceID

Identifier of an MCI device. This identifier or alias is assigned when the device is opened.

lpszPalette

One of the following flags.

Value Meaning
background Realizes the palette as a background palette.
normal Realizes the palette for a top-level window. This is the default setting.

lpszFlags

Can be "wait", "notify", or both. For digital-video devices, "test" can also be specified. For more information about these flags, see The Wait, Notify, and Test Flags.

Return Values

Returns zero if successful or an error otherwise.

Remarks

Use this command only if your application uses a window handle and receives a WM_QUERYNEWPALLETTE or WM_PALETTECHANGED message.

The following command tells the "myvideo" device to realize its palette:
