    cant overload the dispose method of a picturebox

    I have a class which inherits from PictureBox. I want to overload the Dispose sub, but I can't.
    VB Code:
    1. Public Overloads Overrides Sub Dispose()

    2.     End Sub


    when I run my app, it gives me this error:
    An unhandled exception of type 'System.TypeLoadException' occurred in Paint Mall.exe

    Additional information: Declaration referenced in a method implementation can not be a final method. Type: PaintMall.Ruler. Assembly: Dispose.

    Overrides Overloads Protected Sub Dispose(ByVal disposing As Boolean)

    That is what the MSDN library has for it.

    hmm, when I'm accessing my control from the Form, I see it as Dispose() , while it's declared as Dispose(boolean) in the control. Why is it? is it because of the protected keyword?
