Recording Audio in ASF format using Visual Basic 6 on Windows 7

Hi everyone,

This is my first post at VBForums, :) Sorry if my english isn't perfect, I'm brazilian.

I'm really needing some help. The situation is:

One client of the company where I work have an old VB6 application that currently runs smoothly on Windows xp. One of the features of that app is the capability to record audio in ASF format. For that purpose, the application uses an "ancient" tool, NetShow. OK, it works fine and do the job. But The problem is: the client wants to make the app compatible with Windows 7, but NetShow no longer work for this platform. Since the beggining of the idea of making the app compatible with Windows 7 I knew that. But the client want me at least to try to make it work. So I'm doing research to find something that might work. Well, so far I have discarded these options:

- Microsoft Media Foundation: recent, C++ language, don't have an API that works with VB6 - incompatible;
- DirectSound (DirectX): not recent, but the same situation above;
- Windows Media Encoder / Windows Media Services: No longer supported.

As you can see, my options are dwindling, and I don't have the answer yet.

So, there is any possible (and compatible) component/library/app that I can use with VB6 code in order to make it work on Windows 7? If no, OK, I'll have to tell to the client that we will have to develop a new application, with more recent/supported technology (C# or C++), an idea that I totally agree with.

Thanks for any help, and sorry for the long post.
