including wchar_t *, implement wide character formats. To convert a string between a multibyte and a wide character format, you can use a single function call like mbstowcs_s or a constructor invocation for a class like CStringA.

The strings types that are covered includechar *,wchar_t*,_bstr_t,CComBSTR,CString,basic_string, andSystem.String. In all cases, a copy of the string is made when converted to the new type. Any changes made to the new string won't affect the original string, and vice versa. ...
