Calling base class virtual method

[Raider]

I have class hierarchy with virtual methods like this:

class Base
{
public:
virtual void Show();
~Base();
};

class Derived : public Base
{
public:
virtual void Show();
void DoDerivedStuff();
~Base();
};

And I have a function dealing with Derived objects:

void foo(Derived& d)
{
d.DoDerivedStuff();
d.Show(); // <- but here I want to call Base::Show(),
// not Derived::Show()
// (or even DerivedDerived::Show())
}

What should I write to call Base::Show() in foo()?

Should I write special adaptor like this
void Derived::BaseShow()
{
Base::Show();
}
and call it? Or may be there is a simpler way?

What should I write to call Base::Show() in foo()?

I tried pointer to member function:
(d.*(&Base::Show))();

But it calls Derived::Show() :-(

Close - but you must avoid using a function pointer for it to work:
d.Base::Show(); // shall do
