vb3 multichannel wav support

I need to know if it's possible, and if so how can I play at least 2 wavs as the same time using VB3 standard 16-bit code/API calls?  If I can at least get 2 wavs to play at the same time I will be happy...  I know it can be done with other languages...but how bout in this case?  Please provide code if possible...

It can be done by mixing the two wav files yourself and then playing the resulting file.

That would defeat the purpose...and take up way too much hd space.

You can mix the two file yourself in memory in small chunks or look for Microsoft's WaveMix.dll which does it for you.

I'm gonna look for this dll, but if I don't find it, how would I mix 2 wavs in memory in vb3????  Is there some API calls or something that do it? (I DO NOT have MCI.VBX)

Check for sound card driver with
  waveOutGetNumDevs
Get the capabilities of them all with
  waveOutGetDevCaps
If there is more than one ask the user which he wants to use
Open the selected devices at the selected format with
  waveOutOpen

Mix and write the data to memory using arrays

Prepare the data for playback with
  waveOutPrepareHeader
Send it to the device with
  waveOutWrite
Send another just after, it will be put in the queue.

In a loop with a DoEvents, Check for the WHDR_DONE flag in the WAVEHDR structure of the first buffer. This will in dicate that the first buffer has finished its playback.
At this time, you will clear the first array and use it to place and prepare a third data block and send it to the device.
Continue like this until all data had been played.

Allways check for error, if anything appends :
  waveOutGetErrorText
and show this error to the user and ask him want to do next

When you are done :
   waveOutClose

If you need the Windows 3.1 Multimedia reference, give me your email and I will send it to you. It is a 340k windows help file.

Tell me if you can't make it work. But tell me if you succeed too !
