Inheritance Question

[MikeB]

I am getting an error I did not expect:

C:\Development\Inform2K4\TaskPlanPage.cpp(91) : error C2248: 'SetBoundary' : cannot access protected member declared in class 'CTaskPlanPageObject'

class CTaskPlanPageObject
{
       CTaskPlanPageObject();
       virtual ~CTaskPlanPageObject();
protected:
       virtual void SetBoundary(const CRect& rcBoundary);
protected:
       CRect m_rcBoundary;
};

//.cpp
void CTaskPlanPageObject::SetBoundary(const CRect& rcBoundary)
{
        m_rcBoundary = rcBoundary;
}

class CTaskPlanPageHeader : public CTaskPlanPageObject
{
         CTaskPlanPageHeader();
         virtual ~CTaskPlanPageHeader();
};

Now, if I have a CTaskPlanPageHeader object, shouldn't calling SetBoundary() be OK? Or do I not understand inheritance?

void CTaskPlanPage::SetPageSize(const CSize& szPage)
{
        .....
        m_Header.SetBoundary(rcBoundary);
}
