Hello,

Can someone tell me why VS C++ .NET inserts _tmain and not main when
creating a project? Also, whats the deal with the _T before the various
types (e.g. _TCHAR)?

T.I.A.

They isolate you from differences in character type with between
Unicode (2 byte characters) and ANSI/MBCS (1-byte/multi-byte
characters). By using those, you should be able to compile for
ANSI/MBCS or Unicode without making any code changes.
