Network programming

[leangross]

hi, im new in network programming....
most of the articles i've read requires a server and a port to connect to... just wondering how will i know which port to use?

I want to test the sample code i got from one the website i read. I tried assigning 8000 to the port but it gave me this error, "Message : No connection could be made because the target machine actively refused it"

When i change the port to 80 it did give me any error message at all... Is there a way to know which port i can use? im using my local machine for testing (localhost).

Hope someone could help me understand these things clearer...

it was the firwall that refused your connection to port 8000. Open it for incomming trafic and you should fine.

Everything above 1500 and less then 65000 should be fine.

hi thnx for your reply... but how could i open a port for incomming traffic?

You will need to create the server(tcplistener) and client parts of your application to put on both machines. The connection was refused because there was nothing on the other side of that port.

Heres a random link to give you an example:
