You should change it from _MBCS to UNICODE, all you also need to make all
the code changes outlined in Joe's response to you.

I think you need both, UNICODE and _UNICODE.

Yes, one is for the Windows api, the other for the C runtime, if
memory serves.

Thats how I recall it.

You would typically want to first create a new configuration, e.g., "Unicode Debug", and
create it from "Debug". Then delete the MBCS conditionals and add both UNICODE and
_UNICODE, and build with that configuration. By doing it with a completely new
configuration, you have a fallback when there are problems; you can build the ANSI version
and test it. If you get the same failure, it isn't in the Unicode logic.

Once you've got it debugged, do the same to build a Unicode Release. Also, you will have
to change the main entry point; look up WinMain(a)16 in the MSDN help and follow the
instructions there about changing the entry point name.
