Hi I was trained in college for 3 years in c and c++ during that whole time (15 years ago) we didnt study anything about libraries. I've been able to learn bits and pieces, and Im not trying to start a negative topic, but where on earth do people learn about dlls and libraries other than through quick one page explainations? I'm learning some old COM stuff and making my own libraries us a strong interest of mine now. Can some people refer me somewhere?
