This code was used to implement the Tic-Tac-Toe game and play it through the LAN with a friend. Of course, we use the TCP protocol to send instructions.
The TCP protocol is used to send reliable data through the network. In order to understand this code well, you must first have a general overview about the TCP transmission protocol.
Using the Code
In this project, we have two separate programs, one for the server that manages the entrance of the players and to hold messages from one player to another. The other program is the part for the clients (i.e. players) that listen to any messages coming from the server. It also performs some Event Handlers and the most important part is THREADING. For the clients, they are TCP clients for the server that listen at port 5000 for client requests.
Parts from the code look like this:
TcpClient client = new TcpClient("localhost", 5000);
output = client.GetStream();
writer = new BinaryWriter(output);
sendr = (PictureBox)sender;
TcpListener tcplistner = new TcpListener(5000);
welsock = tcplistner.AcceptSocket();
networkstream = new NetworkStream(welsock);
reader = new BinaryReader(networkstream);
writer = new BinaryWriter(networkstream);

I Graduated from Biomedical and Systems Engineering july 2008 department faculty of engineering cairo university. and am interested in the field of Biomedical Engineering Software. as i think its very powerful & interseting field.
