can I use strlen with LPCTSR ?

Hi Lucy!

You should use

_tcslen

also all other tchar-function, if you are using TCHAR or LPCTSTR or LPTSTR

See: Generic-Text Mappings in TCHAR.H

If you sure that you're never going to do a Unicode build, you *can*,
but that doesn't mean you should. Instead of a const char*, LPCTSTR is
actually a pointer to a TCHAR, which changes depending on your build.

To be safe you should always use the _tcs variants of string functions.
Typically you just replace the prefix "str" with "_tcs", e.g.:

strcmp --_tcscmp
strlen --_tcslen

And so on.
