If there is no lp parameter, this constructor initializes the p data member to NULL. If lp points to an IDispatch interface, the constructor sets p to that interface and calls AddRef. If lp points to an IUnknown interface, the constructor calls QueryInterface for the IDispatch interface and sets p to that interface.
