a - seems to me like you have to read some basic stuff about VC++, don't investigate too much time, but I guesss a bit more is still acceptable.
Compiling is not a 5-min-fun, using own compiles is still fine and after such a procedure you learned a lot, but this still needs some time and of coarse some drops of sweat.
b - disfigure users names is frowned upon, not that it ails me but it is reasonably part of any forum's etiquette, written or not
c - you've got a wrong impression, I'm not that needless (even if my ma tells me every time

)
PostScriptum: about b - thx, seems like you have fixed this
PostScriptum 2: I admire your MATLAB-project and your students-work. I guess
compiling with VC++ is not that neccessary, just try it with MATLAB from the start
