Parameters

object

Object associated with this media control interface command. The object can be one of the following:

Device type
Device name
Filename
Alias

AUDIO: Sets the audio attributes of the device context specified by the ALL, LEFT, RIGHT, OVER, and VOLUME keywords.
ALL: Applies to both/all channels (default). Specify ON or OFF with the ALL keyword.
ON: Enables audio output (or enables audio output to the left/right channel).
OFF: Disables audio output (or disables audio output to the left/right channel).
LEFT: Applies to left channel. Specify ON or OFF with the LEFT keyword.
RIGHT: Applies to right channel. Specify ON or OFF with the RIGHT keyword.
OVER milliseconds: Applies the change over the specified time period (fade).
VOLUME percentage: Sets the device/mixer channel volume level.
CHANNEL number: Channel number to set for the given device.
AUDIO DEVICE: Channel set pertains to the audio device.
DOOR CLOSED: Retracts the tray and closes the door, if possible.
DOOR LOCKED: Locks the media cover on the device (if any). This disables manual ejection of the media from the device.
DOOR OPEN: Opens the door and ejects the tray, if possible. This enables manual ejection of the media from the device.
DOOR UNLOCKED: Unlocks the media cover on the device (if any). This enables manual ejection of the media from the device.
TIME FORMAT MILLISECONDS: Sets time format, to milliseconds. All position information is in this format after this command. You can abbreviate milliseconds as ms.
TIME FORMAT MMTIME: The time format is set to MMTIME.
TIME FORMAT MSF: Sets the time format to mm:ss:ff, where mm is minutes, ss is seconds, and ff is frames. All position information is in this format after this command.
TIME FORMAT TMSF: Sets the time format to tt:mm:ss:ff where tt is tracks, mm is minutes, ss is seconds, and ff is frames. All position information is in this format after this command.
WAIT: The command is executed synchronously. The function waits until the requested action is complete before returning to the application.
NOTIFY: The command is executed asynchronously, allowing control to be returned immediately to the application. When the requested action is complete, an MM_MCINOTIFY message is sent to the application window procedure.
