I have a CString with a numeric string in it. In the past, I would use
atoi( ) to convert to an int. That doesn't work with Unicode though.

What is the proper Unicode method for converting a CString to an
integer?

Proper method is _ttoi/_ttol. CString is a class that
contains generic characters: TCHAR's. So, when working with
it you need to use generic routines.

If you're using MSVC7[.1], then there is CStringT class now.
It has CString generic specialization; and CStringA and
CStringW for ANSI and Unicode, respectively.

Thanks everyone for your suggestions! Problem is now solved, and I am on
to bigger and (hopefully) better things. :-)
