RE: [Boost-users] lexical_cast and wstring on VC 2003

Hi Steve,

The first one:

int foo = boost::lexical_cast< int >( std::wstring( L"1" ) ); should work. I
do it all the time. However, I believe you have to set "treat wchar_t as
built in type" in your VC++ 7.1 project settings.

You cannot use lexical cast to convert from string to wstring and back. My
suggestion is to write a string_cast<char type> that uses the proper Win32
functions to do the conversion.
