Hi. I am using xampp to set up a server.

Now my problem is that how to connect program running on the other computer to the server computer.

What port is the server using? You need to know that. The server should be listening on that port for connection requests, so your client would use a TCP/IP connect call to the server computer with that port.

How can i identify what port a server computer use? And how the connection string look like?

Whats next how can i query information from the server computer to my computer??
