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
);


Parameters

uType

Specifies the sound type, as identified by an entry in the [sounds] section of the registry. This parameter can be one of the following values:

Value Sound
0xFFFFFFFF Standard beep using the computer speaker
MB_ICONASTERISK SystemAsterisk
MB_ICONEXCLAMATION SystemExclamation
MB_ICONHAND SystemHand
MB_ICONQUESTION SystemQuestion
MB_OK SystemDefault


Return Values

If the function succeeds, the return value is nonzero.
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.
