Well, I'm not sure I understand correctly, but I think the solution is
derivation:
class Base{};
class A:public Base{};
class B:public Base{};
...


Then you can do:
Base *var;
var = new A;
delete var;
var = new B;
delete B;

All functions, which you want to call by accessing "var" (e.g.
var->Function()) have to be defined as virtual function in class Base.

Does that solve your problem?
