Hi Terry,

You can pass the instance of Form1 to Form2 in the constructor. Use the Baseform class as the type to pass to Form2. This technique allows you to write more generic code that works with families of objects, making use of object-oriented polymorphism rather than coding to a specific class. All methods marked as virtual (C#) or Overridable (VB.NET) will have the methods called in the specific class and not the base class.
