The MCI_INDEX command turns the on-screen display on or off. VCR devices recognize this command.
To send this command, call the mciSendCommand function with the following parameters.
MCIERROR mciSendCommand( MCIDEVICEID wDeviceID, MCI_INDEX, DWORD dwFlags, (DWORD) (LPMCI_GENERIC_PARMS) lpIndex );
Device identifier of the MCI device that is to receive the command message.
MCI_NOTIFY, MCI_WAIT, or MCI_TEST. For information about these flags, see The Wait, Notify, and Test Flags.
Pointer to an MCI_GENERIC_PARMS structure. (Devices with extended command sets might replace this structure with a device-specific structure.)
Returns zero if successful or an error otherwise.
The information presented in the on-screen display is controlled by the MCI_VCR_SET_INDEX flag in the MCI_SET command.
The following additional flags apply to VCR devices:
