Opening a Compound Device by Using the Filename

The following example opens the waveform-audio device by specifying a waveform-audio file named "TIMPANI.WAV" using the mciSendCommand function.

UINT wDeviceID;
DWORD dwReturn;
MCI_OPEN_PARMS mciOpenParms;
// Opens a waveform-audio device by specifying the device and 
// file name.

mciOpenParms.lpstrDeviceType = "waveaudio";
mciOpenParms.lpstrElementName = "timpani.wav";

if (dwReturn = mciSendCommand(NULL, MCI_OPEN,
    // Error, unable to open device.

// The device opened successfully; get the device ID.
wDeviceID = mciOpenParms.wDeviceID;
