<cvt/wstring>
The latest version of this topic can be found at <cvt-wstring>.
The header <cvt/wstring> in previous versions of Visual Studio defined the template class wstring_convert Class in the stdext::cvt namespace. The header is maintained for backward compatibility. New code should use the version of the class that is defined in <locale> in the std namespace
Syntax
#include <cvt/wstring>
