MessageBeep
The MessageBeep
function plays a waveform sound. The waveform sound for each sound type is
identified by an entry in the [sounds] section of the registry.
BOOL MessageBeep(
|
UINT uType |
// sound type |
|
); |

Return Values

If the
function fails, the return value is zero. To get extended error information,
call GetLastError.
Remarks
After queuing
the sound, the MessageBeep function returns control to the calling
function and plays the sound asynchronously.
If it cannot
play the specified alert sound, MessageBeep attempts to play the system
default sound. If it cannot play the system default sound, the function
produces a standard beep sound through the computer speaker.
The user can
disable the warning beep by using the Control Panel Sound application.
