Function name: PlaySound

Defined in : winmm

Requirements : Windows NT 3.1 or later; Windows 95 or later

Declaration:

Declare Function PlaySound Lib "winmm.dll" Alias "PlaySoundA" (ByVal lpszName As String, ByVal hModule As Long, ByVal dwFlags As Long) As Long

Parameters:

* pszSound A string that specifies the sound to play. If this parameter is NULL, any currently playing waveform sound is stopped. To stop a non-waveform sound, specify SND_PURGE in the fdwSound parameter. Three flags in fdwSound (SND_ALIAS, SND_FILENAME, and SND_RESOURCE) determine whether the name is interpreted as an alias for a system event, a filename, or a resource identifier. If none of these flags are specified, PlaySound searches the registry or the WIN.INI file for an association with the specified sound name. If an association is found, the sound event is played. If no association is found in the registry, the name is interpreted as a filename. * hmod Handle of the executable file that contains the resource to be loaded. This parameter must be NULL unless SND_RESOURCE is specified in fdwSound. * fdwSound Flags for playing the sound. The following values are defined: SND_APPLICATION The sound is played using an application-specific association. SND_ALIAS The pszSound parameter is a system-event alias in the registry or the WIN.INI file. Do not use with either SND_FILENAME or SND_RESOURCE. SND_ALIAS_ID The pszSound parameter is a predefined sound identifier. SND_ASYNC The sound is played asynchronously and PlaySound returns immediately after beginning the sound. To terminate an asynchronously played waveform sound, call PlaySound with pszSound set to NULL. SND_FILENAME The pszSound parameter is a filename. SND_LOOP The sound plays repeatedly until PlaySound is called again with the pszSound parameter set to NULL. You must also specify the SND_ASYNC flag to indicate an asynchronous sound event. SND_MEMORY A sound event’s file is loaded in RAM. The parameter specified by pszSound must point to an image of a sound in memory. SND_NODEFAULT No default sound event is used. If the sound cannot be found, PlaySound returns silently without playing the default sound. SND_NOSTOP The specified sound event will yield to another sound event that is already playing. If a sound cannot be played because the resource needed to generate that sound is busy playing another sound, the function immediately returns FALSE without playing the requested sound. If this flag is not specified, PlaySound attempts to stop the currently playing sound so that the device can be used to play the new sound. SND_NOWAIT If the driver is busy, return immediately without playing the sound. SND_PURGE Sounds are to be stopped for the calling task. If pszSound is not NULL, all instances of the specified sound are stopped. If pszSound is NULL, all sounds that are playing on behalf of the calling task are stopped. You must also specify the instance handle to stop SND_RESOURCE events. SND_RESOURCE The pszSound parameter is a resource identifier; hmod must identify the instance that contains the resource. SND_SYNC Synchronous playback of a sound event. PlaySound returns after the sound event completes.

Returns:

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.
