Sound Card, Paralel Port ----------- Visual C++

[Guest_imported]

Hi
Anyone could help me in this question?

I need play and record sound using the sound card in the same time. I need using the paralel port in the same time too.
I'm trying with Visual C++ because i need work in real time but i'm learning.

Thanks in advance.

It sounds like you need to start separate threads to read/write from those devices. Look in the MSDN library for:
BeginThread (Win32 API)
_beginthreadex (Visual C++ library version)
KB article: Q108433
CWinThread (if you're using MFC)
AfxBeginThread

You'll also want to go slowly on this and make sure your design is multi-thread clean. You cannot write to the same variable in different threads without a lock being in place, otherwise you will pull your hair out trying to debug why it's acting weird (it'll behave differently every time!)
