As usual .. when i have a problem ... daniweb.com is here ;). So I need some information from you. Ok, let me explain ... I am currently developing a chat application ! Ok ... everything works fine till now but I have doubts.
My application uses 3 ports, one for the general chat room, one for personal chat and one for file transfer. I have used 3 random ports .. 4321, 4532 and 4533.
Is there a standard port to used?
What will happen if I run this application on a computer where these 3 ports is in used?
And finally, how to know if a port is in used or not ?
Thanks a lot for your answers guys.
