    hi all,

    i'm getting an error when trying to insert items into a map.

    // define types....
    typedef std::basic_string< TCHAR > tstring;
    typedef std::map< tstring, tstring> STRINGMAP;
    typedef std::pair< tstring, tstring > StringPair;

    class A
    {
     .....
      STRINGMAP m_properties;
     .....
    }

    in my code i do the following....

    m_properties.insert( StringPair( _T("key"), _T("value") ) );

    and get the following errrors.
