This is a simple chat program to demonstrate usage of the DirectPlay APIs.
Visual C++ may include older versions of the DirectX header files and libraries. This sample requires DirectX 5. In order to avoid compile errors, make sure the path to the DirectX 5 header files and libraries is listed BEFORE the Visual C++ header files and libraries on the Directories menu, found under Options on the Tools menu.
