using mci functions

[jd21]

I'm programming a win32 console app in Visual C++ Express to play a cd from my laptop. The problem is mcisendstring keeps returning the same error (292)

'The specified command requires and alias, file, driver, or device name. Please supply one.'

Can anyone see my problem??

Thanks


My code:

char szErrorBuf[MAXERRORLENGTH];
char cd_desc[] = "cdaudio";
char alias[] = "MyCDAudio";
char mciCommand[128];

sprintf(mciCommand, "open %s alias %s", cd_desc, alias);

// opens cd audio device as MyCDAudio
DWORD dwtemp = mciSendString((LPWSTR)mciCommand, 0, 0, 0);

mciGetErrorString(dwtemp,(LPWSTR) szErrorBuf, MAXERRORLENGTH);
