Nope, because you didn't even read the link I posted, which explains your second question ("why not just..."), and even predicted in the same link your followup attempt.

Or you did, and you either didn't understand it or are indeed trolling. In either of those cases, I will be of little use to you.

And finally, for clarity and without the scarcasm, for one final attempt at assistance in the event you are truly serious and just dense: it is because while your questions are indeed trivial to google and learn because an absurd amount of beginner and expert info is written on the net about them, it is nontrivial to recreate even beginner answers in post form. It will be long, redundant with the rest of the web, and any given beginner has strong and weak areas of knowledge. Google and the web has the answers to all of this. While I also probably have most of those answers, they came from where I'm sending you, and it's inefficient to do otherwise.
