ok this must be obvious

Wait a sec.. By the looks of it, you are like imitating the mirage chatting system. To make a basic chat system, you really dont need all those packets, unless of course you have those shouts (broadcast, tell player, global, etc..) But anyway, if you are just gonna make a regular chat, why not just send the text over to the server and from server to client with the winsock function 'SendData'.

Code:

frmClient.Winsock.SendData

then in the server, have it recieve it with the GetData function.
