Hello
I have make game chat app for my friends, but I keep constant crash with
winsock control and when communication lose, sw automaticly try new connection, at that point, we all see 3-4 even more names (duplicate names ) that are connected but in fact, winsck didnt close properly and show's like I have described already.

I dont want to change nothing in my sw, I just need to know how to remove duplicate names from listbox.
