winsock users

i have a chat room and want to display all the users that are online. how do i do it???

I can't give you the code since I don't know how you identify each connection but, alls you should need to do is have a text box with label and upon connection have them send a username. Then just have another label on the side which has all the current users...every time a connection ends or becomes connected you send a packet to every user updating the current user list.
