.wav files playing from C++

I was wondering how I would go about playing a single .wav file as a background sound from my C++ application. I have noticed on this board a referance to the windows func PlaySound(). What would be the best way to implement this from C++. Code examples would be appreciated.



Thanks in advance

    The PlaySound function plays a sound specified by the given filename, resource, or system event. (A system event may be associated with a sound in the registry or in the WIN.INI file.)



    BOOL PlaySound(



    LPCSTR pszSound,

    HMODULE hmod,

    DWORD fdwSound

    );





    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.







    Return Values



    Returns TRUE if successful or FALSE otherwise.



    Remarks



    The sound specified by pszSound must fit into available physical memory and be playable by an installed waveform-audio device driver. PlaySound searches the following directories for sound files: the current directory; the Windows directory; the Windows system directory; directories listed in the PATH environment variable; and the list of directories mapped in a network. For more information about the directory search order, see the documentation for the OpenFile function.



    If it cannot find the specified sound, PlaySound uses the default system event sound entry instead. If the function can find neither the system default entry nor the default sound, it makes no sound and returns FALSE.

    Funny, I was just playing around with this about an hour ago and I got it to work (my first time trying to do something like this) and now I come here and see this question.



    Here is a snipet of code using PlaySound that worked in my app:



    if( !PlaySound( "C:\Windows\Media\Homer_WooHoo.Wav", NULL ,

    SND_FILENAME | SND_SYNC | SND_NOWAIT ) )

    {

    cout << "Could not play the sound file." << endl;<br>
    }



    This played a wav file of Homer Simpson I have on my computer saying "Woo Hoo".



    My app was built weeks ago as a simple 32-bit console app using MSVC++ 6.0. I just decided to add this on a whim to see if I could get it working. You must include the mmsystem.h header file to get the PlaySound function definition and you must explicity tell the compiler to link in the WinMM.Lib library to get this to work. I think my app was also using MFC but I don't now if that makes a difference. If you are using a different compiler, I don't know if you will have these libraries/header files.



    Good luck.
