Syntax

  UINT uType
);

Parameters

The sound to be played. The sounds are set by the user through the Sound control panel application, and then stored in the registry.

This parameter can be one of the following values.

Return Value

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 Sound control panel application.

Note  To send a beep to a remote client, use the Beep function. The Beep function is redirected to the client, whereas MessageBeep is not.
