Working on a stepmania modification that uses the whole keyboard. Possible?

Right, so I do have visual studio installed on my pc which could help make this easier but its giving me a project incompatable error. I'm using visual studio 2013 for windows. Any ideas on whats going on?

Edit: Nevermind. I fixed it.

I am imagining a dance pad that has all the inputs of a keyboard for this... MASSIVE

Lol! I wasn't planning on THAT but that is a hillarious concept! Imagine using one of those on a death metal song! Madness!
