I am trying to learn winsock ,and I thought I understood it until I tried to make a simple server and client app. I tried to adapt the Source Code from the Winsock 2 for Games article in the Articles section of the site, and I thought I had it working until I tried to connect to my server app from the client. I start the server up and it starts listening for connections. When I execute the client app, it doesn't connect. I have tried everything I can think of, but I cant get it to work, can anyone tell me what I am doing wrong here? Server
