If this is what your want to do I think you would be better off with lass Base { ... virtual .. } class D1 : public Base { } Base* bp1 = new D1(..some thing..); Base* bp2; ar << bp1; ar >> bp2; this might require registration or export though.

Oh, that should be easy:

D1 *d1p;

ar << d1; ar >> *d1p;

Hi, At

ar << d1; ar >> bp; // but "bp" points already to an object of type D1

I meant : "bp" is "Base* bp" So, if I call ar >> *bp; the Base::load will be called, not the derived D1:load. Actually more precisely, I intend to do so lass Base { ... virtual ..}class D1 : public Base {}Base* bp1 = new D1(..some thing..);Base* bp2 = new D1(..some thing else..); ar << *bp1; ar >> *bp2; This means for all my serializable classes I have a kind of "=" operator defined. regards, Andrei ------------------------------------------------------------------------------ Invite your mail contacts to join your friends list with Windows Live Spaces.
