Playing WAVE Resources

You can use the PlaySound function to play a sound that is stored as a resource. Although this is also possible using the sndPlaySound function, sndPlaySound requires that you find, load, lock, unlock, and free the resource; PlaySound achieves all of this with a single line of code.

PlaySound Example

PlaySound("SoundName", hInst, SND_RESOURCE | SND_ASYNC);

sndPlaySound Example

The SND_MEMORY flag indicates that the lpszSoundName parameter is a pointer to an in-memory image of the WAVE file. To include a WAVE file as a resource in an application, add the following entry to the application's resource script (.RC) file.

soundName WAVE c:\sounds\bells.wav

The name soundName is a placeholder for a name that you supply to refer to this WAVE resource. WAVE resources are loaded and accessed just like other application-defined Windows resources. The PlayResource function in the following example plays a specified WAVE resource.

BOOL PlayResource(LPSTR lpName)

{

BOOL bRtn;

LPSTR lpRes;

HANDLE hResInfo, hRes;

// Find the WAVE resource.

hResInfo = FindResource(hInst, lpName, "WAVE");

if (hResInfo == NULL)

return FALSE;

// Load the WAVE resource.

hRes = LoadResource(hInst, hResInfo);

if (hRes == NULL)

return FALSE;

// Lock the WAVE resource and play it.

lpRes = LockResource(hRes);

if (lpRes != NULL) {

bRtn = sndPlaySound(lpRes, SND_MEMORY | SND_SYNC |

SND_NODEFAULT);

UnlockResource(hRes);

}

else

bRtn = 0;

// Free the WAVE resource and return success or failure.

FreeResource(hRes);

return bRtn;

}

To play a WAVE resource by using this function, pass to the function a pointer to a string containing the name of the resource, as shown in the following example.

PlayResource("soundName");
