You probably want to write a client-server based program, where one PC is
the server and the other one is the client, using sockets. This is not
difficult and you can get read about it in any book that discusses TCP/IP
programming or in the example programs that come with MS Visual C++. You
can certainly write the client in VB and maybe the server, too. The only
issue might be the latency in communicating between the two programs.
NT/95 might not give you the deterministic behaviour that you need for
Then you need to design how the client and server interact... there's a
lot to this.
Hope I've given some ideas,
