is it possible to put C code into a .cpp? if so could somebody fill me in on how or what to search for on MSDN?

Yes, but you can''t do it the other way around. C++ is an extension of C.

Yup.

  extern "C" {// C declarations and C code}  

You''re going to want to do this for the function declarations (in the .h) and the functions themselves (in the .cpp)

thanks
