MCIWndSendString

The MCIWndSendString macro sends an MCI command in string form to the device associated with the MCIWnd window. You can use this macro or explicitly send the MCIWNDM_SENDSTRING message.

LONG MCIWndSendString(
  hwnd,  
  sz     
);
 

Parameters

hwnd

Handle of the MCIWnd window.

sz

String command to send to the MCI device.

Return Values

Returns zero if successful or an error otherwise.

Remarks

The message handler for MCIWndSendString (and MCIWNDM_SENDSTRING) appends a device alias to the MCI command you send to the device. Therefore, you should not use any alias in an MCI command that you issue with MCIWndSendString.
