std::string in unicode builds

[ranadhir]

Let us take a simple function
::MessageBox(0,data.c_str(),"log",0);
where data is a std::sting type.

When i change the build type to unicode ,this will spit out error
error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'const char *' to 'LPCWSTR'

How can i feed in the underlying data of a std::string type(const char *),so that it builds smoothly in both MBCS and UNICODe builds.

There's also a std::wstring type.
If that works, maybe you could do something like:

#ifdef UNICODE
   typedef String std::wstring;
#else
   typedef String std::string;
#endif //UNICODE
