There is not concept of "parent object" without you explicitly defining it
in your code. The easiest way to accomplish this is just to have a reference
to the parent object in the child object. The only reason things like
windows controls and web controls have a notion of parent is because MS
coded it that way (basically like what I have below).
Public Class Quiz
Private m_Questions As New QuestionCollection()
Public Sub New(...)
...
For ...
m_Questions.Add( New Question(Me) )
Next
End Sub
End Class
Public Class Question
Private m_Parent As Quiz
Public Sub New( parent As Quiz )
m_Parent = parent
End Sub
End Class
