64 bit or 32 bit application

[Sonic..]

Is there any way or any function provided in vc++ by which i can
determine if my module or application is a 32 bit or a 64 bit
application.

Why not ask on a VC group? There's probably an integer type (long
long?) that indicates size.

Actually my money would be on size_t, so in a way the question has a
standard answer, so is ON TOPIC!

I'd probably also try pointer sizes. Or ptrdiff_t size. However,
there is probably a macro that some compilers define which can be
easily used for the "target bit-ness".

MS VC Defines "_WIN32" and "_WIN64" as appropriate, e.g.

#ifdef _WIN64
/* 64 bit stuff
#endif
