The only thing the ocx code does is hook the game to the chat client, you can use the OCX in your projects if you want or you can use the code.

When you hook the game to the chat client it puts the game in the list so others can join and play or just watch. It is sub classing using WM_VOODOO to communicate with the client. This works just like Winsock when you use the OCX.

The new Voodoo will include either a DDE interface or use WM_COPYDATA although the old interface will still be there using WM_VOODOO.

Mine and Arachnids game examples both show you how to start out, then you just build a game from scratch.
