At the time of writing this answer, the number one google search for "convert string wstring" would land you on this page. My answer shows how to convert string to wstring, although this is NOT the actual question, and I should probably delete this answer but that is considered bad form.

Here's a way to combining string, wstring and mixed string constants to wstring. Use the wstringstream class.

#include 

std::string narrow = "narrow";
std::wstring wide = "wide";

std::wstringstream cls;
cls << " abc " << narrow.c_str() << L" def " << wide.c_str();
std::wstring total= cls.str();
