MCI_REALIZE command

The MCI_REALIZE command causes a graphic device to realize its palette into a device context (DC). Digital-video devices recognize this command.

To send this command, call the mciSendCommand function with the following parameters.

MCIERROR mciSendCommand(
  MCIDEVICEID wDeviceID, 
  MCI_REALIZE, 
  DWORD dwFlags, 
  (DWORD) (LPMCI_GENERIC_PARMS) lpRealize
);

Parameters

wDeviceID

Device identifier of the MCI device that is to receive the command message.

dwFlags

MCI_NOTIFY, MCI_WAIT, or, for digital-video devices, MCI_TEST. For information about these flags, see The Wait, Notify, and Test Flags.

lpRealize

Pointer to an MCI_GENERIC_PARMS structure. (Devices with extended command sets might replace this structure with a device-specific structure.)

Return Value

Returns zero if successful or an error otherwise.

Remarks

You should use this command when your application receives the WM_QUERYNEWPALETTE message.

The following additional flags are used with the "digitalvideo" device type:

MCI_DGV_REALIZE_BKGD

Realizes the palette as a background palette.

MCI_DGV_REALIZE_NORM

Realizes the palette normally. This is the default.

For digital-video devices, the lpRealize parameter points to an MCI_REALIZE_PARMS structure. For more information, see comments in the MCI_GENERIC_PARMS structure.
