simple override question

[StaticPhilly]

hello,

OK i need a little help,

i want to override a funtion from a parent class, but i can seem to get it to work,

so i have a layout the same as below, i want to override the Z function from class A in class B.
when i use this layout below it still calls the Z function from A rather than B, i am creating the object from B so from my understanding it should be overwrote...

can anyone help me out with this?

thanks
Philly

Class A Header:

#pragma once

class A
{
private:
    void Y();
protected:
    virtual void Z();
};

class A Source:

#include "stdafx.h"
#include "A.h"

void A::Y()
{
    this->Z();
}

void A::Z()
{
    // want to override this in class B;
}

Class B Header

#pragma once
#include "A.h"

class B : A
{
protected:
    void Z();
};

Class B Source:

#include "stdafx.h"
#include "B.h"

void B::Z()
{
    // Do Somthing Here!
}
