Hi all,

I have a routine that plays a wav. I call this routine from other routines. The problem that I have is that the calling sub ends up pausing while the wav is played before it completes. I am an amateur programmer. I was wondering if there is a way (separate thread?) to call the routine that plays the wav but have it NOT interupt the rest of my routine?

Thanks in advance.

When using the win32API to play a wav from VB NET you need to first declare the following...

 '//Win32API
    '//Both integer args and return were originally Longs - .NET Integer = vb6 Long
    Declare Function PlaySound Lib "winmm.dll" _
    Alias "PlaySoundA" (ByVal lpszName As String, _
                        ByVal hModule As Integer, _
                        ByVal dwFlags As Integer) As Integer

Then you can make a sub....


Friend Sub PlayAudio(ByVal FileName As String)
        '//call win32api function to play audio (wav) file alert
        Dim retval As Integer
        retval = PlaySound(FileName, 0, 1)
        'last param is SND_SYNC as integer
        'value set to 0 plays sound Synchronously (waits until sound ends before playing next)
        'value set to 1 plays sound Asynchronously (does not wait to play next sound)
    End Sub

in the comments above you'll see that the last param determines if sound waits or or doesn't. If you want you can modify the sub above to take that as a param as well. This is a snippet from an app I wrote for work. This should solve your problem, just use value of 1 to make app not wait for sound to finish. Threads shouldn't be necessary.

hope this helps

Tek,

Thank you. That did the trick. I had a declaration and sub similar to yours and I was running it in ASYNC mode. I guess somewhere, it did not work as I expected. Your code works great. Thanks again.
