Add a virtual function like clone()?

Base *pObj = new Derived();
 Base *pObjClone = NULL;

 const type_info& typeInfo = typeid(*pObj);
 if (typeid(Derived) == typeInfo)
 {
     pObjClone  = new Derived(( Derived & )*pObj);
 }
 else if (typeid(Base) == typeInfo)

     pObjClone  = new Base(( Base & )*pObj);

 /*else if (typeid(...) == typeInfo)

 }*/

     // invalid type

ou see, every function has to be in its own dll

The first argument (string s), and the return value are common for all functions. Is it possible, for example, to have only that one argument (thus achieving uniformity), and take the rest through some kind of message boxes in the function itself? Or is there a better way?
