Need tips on where and how to start coding hacks

Hi, this year I'm enrolled in programming at school. I planned on starting to code my own hacks, and currently, I have a .net step by step book. Is it possible to produce hacks in .net? If so, would it run similar to C++ in speed? I know C++ is preferable, but I currently can't do much of that :3 I also have a Java book but I don't think Java can do much for this, right? Sorry for questions, still pretty new to coding.

if you mean VB.net / C#.net then you can make loaders. Its preferred to use C++ for hacking making. Good luck and have fun.
