[Openal] OpenAL with C++ WindowsForm application?

[Pierre-Henri François]

I had the same problem with previous version, and the solution was to put the non-managed #include in top of the file... as follow (in my case)

	// ILT-TP.cpp : fichier projet principal.
	#include "AudioRecorder.h"
	#include "stdafx.h"

You also need to ask a /clr option (not /clr:pure).
I hope it can help...

I'm not an authority on CLR or Forms, but I do know that if you want to 
use OpenAL with the CLR, you'll have to wrap the library so you can 
access the native OpenAL methods from your managed code.

I don't know much more than that, as I haven't had to do it yet myself.  
Maybe someone else can give you more specific help, or you could do some 
Google searching on using native C functions from managed C++
