Inheritance Troubles

[Illuminator]

I have two classes, one of which is derived from the other.

class CPrimitive
{
public:
    CPrimitive();
    ~CPrimitive();

    void Function1() { Function2() };
    int Get_I() { return i; };

protected:
    Function2() { i=1; };
    int i;
}

class CBox : public CPrimitive
{
public:
    CBox();
    ~CBox();

protected:
    Function2() { i=2; };
}

//The inline functions are actualy declared in a .cpp file and are much
//more complex, but this example still stands.

//In my main code i do something like this
CBox box = new CBox();
box->Function1();

int what_is_I =box->Get_I();

I want Function1 to call the new definition of Function2 in the CBox class and have i=2 returned. However it calls the old Function2 from CPrimitive and returns i=1. Its there any way to get the code to reference the new Definition without redefining Function1 for CBox?

Change Function2 to a virtual function.
