Where should I start?

Hello. I know C# and I'm having issues figuring out what should I learn according to became a hack programmer? There are so many languages, and so many ways, but I could not understand what step should I take to move ahead and get the knowledge to code my own hacks. I would like to have some information and refferals to the stuff that I need to study.
Thanks in advance.

learn C++ and camp at coding section

If ill know the c++ language I should know how to make it? there is nothing else to focus on? because it sounds too extended, not everyone that understands c++ will know how to make hacks, suddenly. So there must be something to focus on, doesn't it?
What about ASM, D3D?
I dont know anything else but C#! are you sure that knowing C++ is the only requiment? and if it is, isnt there is something specific to focus on?
thanks..
