Network Programming Problem

Question

I am writing a program similar to the mIRC. First my program connect to the server in LAN via port 9999. When users click on the list of nicks a private chat form will appear. However when I activate the private chat form by the statement [b]privatechatform.Show()[/b] the private chat form is crashed and my program too. If I change the statement into [b]privatechatform.ShowDialog[/b] it will be ok but I cannot have private chats with multi-users. How can I solve the problem??? or anyone can give me the source code of the program like that.

First try eliminating possibilities. If the problem is in your protocol (either you're wrong or you haven't coded it to do what you meant to) you may find that the behavior is different when you use a telnet client. Next try another chat server. Are you debugging your program when it crashes? If not try it.
