I want to do something like , every time your computer receives a byte or uploads a byte , call a function. But I don't really know what I should google, what references I need to check

This could be an example

Private void ByteReceived(object sender,e as Eventargs)

{

MessageBox.Show("Zomg");

}

That's real vague. Can you be more specific about what you are trying to accomplish? Popping up a message every time your computer transmits or receives a byte wouldn't be very helpful since your computer transmits and receives millions of them each second. What's the overall goal you're trying to reach here?

To elaborate a little there is a concept of ports in computers. A port is just a number (port 80 for web server), 21 for FTP etc.

Basically there are many different programs running on the pc talking to many different programs on the internet. To distinguish which messages is meant for whom, we have a port number e.g. your web browser (IE, Chrome, FF) sends an http request to google server when you type Google. on destination port 80 with the source port being some random value e.g. 4338. The response which contains destination port 4338 would be identified as destined to my browser and forwarded to it.

So each application running is bound to a different port number. Now which one are you interested in?
