[Boost-users] Serializing a Method

Hi to all
I am new to the boost library, I downloaded it and I am doing some tests.
I was using MFC serialization.
I want to do something like this :

template<class _CReceiver, class _CMemberType>
class CASetMemberCommand
{
        friend class boost::serialization::access;

public:
        typedef void (_CReceiver::* Action)(_CMemberType) ;

protected:
        _CReceiver *m_pReceiver;
        _CMemberType m_Property;
        Action m_fnAction;
public:
        CASetMemberCommand()
        {
                m_pReceiver = NULL;
        }
        CASetMemberCommand(_CReceiver *pReceiver,
                Action fnAction,
                _CMemberType memberProperty)
        {
                m_pReceiver = pReceiver;
                m_fnAction = fnAction;
                m_Property = memberProperty;
        }

        ~CASetMemberCommand()
        {
        }

        virtual void Execute()
        {
                if(m_pReceiver)
                        (m_pReceiver->*m_fnAction)(m_Property);
        }

        template<class Archive>
        void serialize(Archive & ar, const unsigned int /* file_version */){
                ar  & BOOST_SERIALIZATION_NVP(m_pReceiver)
                        //& BOOST_SERIALIZATION_NVP(m_fnAction)
                        & BOOST_SERIALIZATION_NVP(m_Property);
        }

        void Save(const char * filename)
        {
                std::ofstream ofs(filename);
                assert(ofs.good());
                boost::archive::xml_oarchive oa(ofs);
                oa << BOOST_SERIALIZATION_NVP(this);
        }

        void Load( const char * filename)
        {
                std::ifstream ifs(filename);
                assert(ifs.good());
                boost::archive::xml_iarchive ia(ifs);
                ia >> BOOST_SERIALIZATION_NVP(*this);
        }

};

int main(int argc, char *argv[])
{

        gps_position pos(32,52,25.0f);
        CASetMemberCommand<gps_position,int> cmd(&pos,&gps_position::SetMinutes,25);
        CASetMemberCommand<gps_position,int> cmd4(&pos,&gps_position::SetDegrees,25);
        cmd.Execute();
        SaveCommand(cmd,"D:/test.xml");

        cmd.Save("D:/Test2.xml");
        CASetMemberCommand<gps_position,int> cmd2;
        cmd2.Load("D:/Test2.xml");

        return 0;
}

the problem is that BOOST_SERIALIZATION_NVP(m_fnAction) is not working
(compile errors);

Is there any way to save a methode of w class, so it can be loaded and
used later?

Thank you
