I´ve made a "main" class lets call it A(Veichle), 
and i have two classes that inherits from A Lets call them B(Car) and C(MC).
i also have a handler lets call it "D" that binds A,B and C. 
Then i have the Form1 class lets call that E(Visual)

I want to print out the private members from A on the visual form "E" in a Listbox

If i try ex) 

this->listbox1->items->add(X.veichles[i]->getBrand());

it complains that veichles is a private member in D.

How can i get around that?
