Class is not a parent of this class: <class name>

• A class specified in a Sub New declaration is not the class from which this one is derived.
• A class specified using "dotdot" notation is not the class from which this one is derived.

For example:

Class BaseClassOne
   Sub New (X As Integer)
   End Sub
End Class
Class BaseClassTwo
   Sub PrintIt
      ' ...
   End Sub
End Class
Class DerivedClass As BaseClassOne
   Sub New(Y As Integer), BaseClassTwo(x%)  
' Illegal because BaseClassTwo is not the base
' class from which DerivedClass is derived.
' The appropriate base class is BaseClassOne.
   End Sub
   Sub PrintIt
      ' ...
   End Sub
   Sub CallPrintIt
      Call BaseClassTwo..PrintIt
' Illegal because BaseClassTwo is not the base
' class from which DerivedClass is derived.
' The appropriate base class is BaseClassOne.
   End Sub
End Class

Correct the reference to the base class.
