I'm attempting to make a program that connects to a ip or something. So like people can connect to it also and chat and stuff.

I have no clue on how to even start this, so can someone please point me in the right direction? :)

Thanks for your time!


I have one more question. How do I change the color of certain things in my textbox, for example;

string Username = "Jayden";
textBox1.AppendText(Username + ": " + input + Environment.NewLine);

I just want the "Jayden" text to change color, but obviously I don't know how.
