Q:

How to read from port#### on home IP 127.0.0.1

I have a program that sends data to the home IP to the port####.
I want to access this and make it readable data. Maybe in C#?
I haven't tried doing this before and I have only a vague idea of doing sockets. 
The program I'm trying access is a UDP. Therefore it's a UDP port reader I need to incorporate on another program.
"####" < is just any random number.

A:

Setup a listener on your Home PC to listen on the port ####
and perform a while loop to accept incoming connections.
Check out this MSDN article
You may need to specify your own high-level communication protocol, example?
Message structure:
01:UserID:MessageText
General Command:
02:UserID:CommandCode
...etc.
You get it, right? Specify an identifier or a keyword to recognize the type of the incoming message and then process the message with a suitable handler.
Network Programming is Fun!
Hope that helps.
