You can reverse engineer some Android torrent downloaders and learn more from them since JAVA classes are completely reversible to full source code.

Assuming you are familiar with JAVA

Some important link: http://www.forensicswiki.org/wiki/Various_Methods_to_Disassemble_DEX_Files

I ever wandered to people suggesting reversing application instead of reading public available specification

Do you really think reverse engineering of Java application will help to assembly developed application???

I didn't die, I just stopped working on this. But now I gained enough energy to dive into this project again.

to learn window programming, a good way would be to start in c++, and give it a try in fasm, just to see that c++ is useless.

An important update for this project is this: format PE GUI 6.0
It means that for now I don't feel like finding out why it crashes the good old xp, instead I'm focusing on more productive things like actually finishing the torrent bencoding process. It doesn't mean that I don't want to make it work on xp, but I personally don't feel like submitting to a 10 years old OS that is officially not supported by M$ anymore.

But since my project is open source, anyone could make it happen. But I would be happier if you gurus just PM me when you know the reason why xp refuses to run this without an appcrash. Not now, but after I completely finish the torrent maker dialog, because there could be more "errors" later on in my code.
