Having trouble listening and writing to a socket

Question

I might as well just post my classes. What I really need is a comprehensive guide to reading and writing to a socket. The sockets aren't being printed, and I know it's because they hang on the "readline()" statements in the netcheck functions. Why do they hang?

Oh yea, I just forgot to flush :)
Everything's fine now - works great. BTW, do you guys
reccomend keeping a socket, or just creating a new
one every time you want to send information?Now why would you want to create a new Socket everytime.From the server once a Sockets bounds to the port you stick by it receive the desired clients.From the client side once a socket establishes a connection with the other host you can keep that socket alive till you carry out the task that you want to and then once you are through close the connection.
