Hi

You won't! This is a Peer to Peer operation similar to napster. I have written a similar application and you will need a *server* app that listens to a static port on a static IP address. Your friends/users need a small client app that will connect to your server app, which will be listening for them using the standard winsock events. When your code detects a connection you can derive the IP address. Now you will have to do the same (connect to server via client etc) and you will be able to see the IP address of anyone who is using your client software.

This assumes however that you all have dynamic IP from your ISP's - if none of you do (which is unlikely) you can connect direct to eachother. Also beware of firewalls - they dont like stuff being put through abnormal port numbers!

This app works well, I suggest you take a look at its code

Create a chat room using the Winsock control.
