Use following :

std::wcout << a.GetString();

Use wcout to print CString to console:

CString cs("Hello");
wcout << (const wchar_t*) cs << endl;

My apologies. I was not finished and got interrupted. Apparently you have to convert to a temporary CStringA (otherwise it is wide string format i.e wcout). I did not realise this until I read your message (again):

std::ostream& operator << ( std::ostream& os, const CString& str )
{ if( str.GetLength() > 0 ) //GetLength??? { os << CStringA( str ).GetString(); } return os;
}

You could as suggested of course just use wcout:

std::ostream& operator << ( std::wostream& os, const CString& str )
{ if( str.GetLength() > 0 ) //GetLength??? { os << CStringA( str ).GetString(); } return os;
}

Then use like this:

std::wcout << str << std::endl;
