get application name by port

okay so i made this application, it monitors all the internet activity of internet, with protocols, so i get information about every packet being sent on internet, including destination and source, but i dont know how to get process name, when i run it shows a like a spam of packets being sent but cant recognize what application/process is sending em, so i want some way to get process of the packet sent.. any confusions?

re: get application name by port

The output of netstat -no contains the ProcessID numbers for the port.
You could parse that?
There is bound to be a better way though.

Also maybe from here:

re: get application name by port

It doesn;'t matter how you get the packets, its how you go from ports->application name that you should be taking from those examples
