accessing protected base class / operators

[corcor]

Hi !

I want derive my class as protected from its baseclass, e.g.

class CMyRect : protected CRect
{
}

because nobody should change CRect directly, but I would like to provide a possibility to get a copy of the base class, e.g.

CMyRect* p = new CMyRect();
CRect r = *p;

or even can access const methods, like

CMyRect* p = new CMyRect();
int n = p->Height();

Is there a possibility to define (an) operator(s) for this ?

Thanks in advance !
