In addition to what keet answered you may want to do definitions for
tstrings to account for Unicode vs. ANSI with something like:

#include <string>
#include <sstream>

namespace std {
#if defined _UNICODE || defined UNICODE
    typedef wstring tstring;
    typedef wstringstream tstringstream;
#else
    typedef string tstring;
    typedef stringstream tstringstream;
#endif
}

Then you can use tstring rather than string in a way similar to using
the _T and TCHAR paradigm for other strings and chars.

Tom:

Yes, this is a useful trick. But extending the std namespace in this way
is actually a sin. So I do it this way:

#if defined _UNICODE || defined UNICODE
    typedef std::wstring tstring;
    typedef std::wstringstream tstringstream;
#else
    typedef std::string tstring;
    typedef std::stringstream tstringstream;
#endif
