No need. What ever you are trying to learn there is a tutorial for. Plenty on this site and asp101.com, learnasp.com etc... Just think of what you want to do and most likely you will find a code snippet that will send you in the right directions. I am fairly new to 4 months or so and there is no better teacher than doing it yourself. Its kinda like learning a foreign language once you know the syntax you'll be fine. Good luck its a blast!
i don't think asp is visable in source code because it is parsed in the server. I am not totally positive about that. Like I said though if you see something you like try to find a tutorial on it most of them have downloadable code with the tutorial. But no matter what you will have to learn it to know how all the pieces fit together. Hope this helps
