Ok, so I'm newb at doing GUI stuff in C++... I need some advice on what kind of control to use for like displaying what is said in the chat.
Once I know what kind of control is best for this, I can do some research on it and figure out how to use it. I'm not using MFC, I'm using the straight up Win32 API.
#include <stdio.h>
printf(incomingstring)
printf is nice and the include file uses less space but for more options use cout.
#include <iostream>
cout << data;
He said GUI, as in, Graphical User Interface. Not a console application. To answer your question, a RichEdit box would be the best for you if you want colors and neat formatting.
Although if he wants it to look really slick and overcome some of the annoying limitations of richedit, he could use GTK+ (http://www.gtk.org/). It's runs on MS-Windows, but it's not standard there.
