Automatically change between std::string and std::wstring according to unicode setting in MSVC++?

Question

I\'m writing a DLL and want to be able to switch between the unicode and multibyte setting in MSVC++2010. For example, I use _T(\"string\") and LPCTSTR

Answer 1

Why not do like the Win32 API does: Use wide characters internally, and provide a character-converting facade of DoSomethingA functions which simply convert their input to Unicode.

That said, you could define a tstring type like so:

#ifdef _UNICODE
typedef std::wstring tstring;
#else
typedef std::string tstring;
#endif

or possibly:

typedef std::basic_string<TCHAR> tstring;
