CAVICapWnd v1.11

Welcome to CAVICapWnd, An MFC class to encapsulate the Video For Windows API.  

Features

• The class provides a familiar MFC interface to the VFW API. The class derives from CWnd and translates the message based VFW API into standard C++ methods.
• All code compiles cleanly at level 4 and is UNICODE enabled.

The enclosed zip file contains the CAVICapWnd source code, documentation and a simple MFC SDI app which implements the same functionality as the VFW SDK sample "AviCap32".
