I am trying to have different types of rectangles. I thought something like this would work, but Rectangle is not a class.

Code:
    Public Class xRectangle
        Inherits Rectangle
    End Class
What I wanted this for was to remove a selection rectangle from an existing drawing. I have all of the objects to draw stored in a list and I am trying to remove the selection rectangle without removing the object it is covering. Hope this makes a little sense.
