Setting the Time Format

Use the MCI_SET command message along with the MCI_SET_PARMS structure to set the time format for an open device. Set the dwTimeFormat member to one of the following constants.

Constant	Time format
MCI_FORMAT_BYTES	Bytes (in pulse code modulated [PCM] format files)
MCI_FORMAT_MILLISECONDS	Milliseconds
MCI_FORMAT_MSF	Minute/second/frame
MCI_FORMAT_SAMPLES	Samples
MCI_FORMAT_SMPTE_24	SMPTE, 24 frame
MCI_FORMAT_SMPTE_25	SMPTE, 25 frame
MCI_FORMAT_SMPTE_30	SMPTE, 30 frame
MCI_FORMAT_SMPTE_30DROP	SMPTE, 30 frame drop
MCI_FORMAT_TMSF	Track/minute/second/frame
MCI_SEQ_FORMAT_SONGPTR	MIDI song pointer

The following example sets the time format to milliseconds on the device specified by the wDeviceID variable:

UINT wDeviceID;

MCI_SET_PARMS mciSetParms;

// Set time format to milliseconds.

mciSetParms.dwTimeFormat = MCI_FORMAT_MILLISECONDS;

if (mciSendCommand(wDeviceID, MCI_SET, MCI_SET_TIME_FORMAT,

(DWORD) &mciSetParms))

// Error, unable to set time format.

return FALSE;

else

// Time format set successfully.

return TRUE;
