Event handlers and scroll bars
Some definitions to learn
•  An object is a thing — anything that appears on the screen.  An object has a set of properties.  Each property of the object has a value. e.g.   Label.Caption = “Welcome to Visual Basic”  where

                             Label is an object
                             Caption is a property of label
                            “Welcome to Visual Basic” is a value of the Caption property.

•  Events are things that happen on the screen.  Event handlers transfer data to procedures that complete the task.  The results of these procedures are returned back to other screen objects, e.g.  onChange   onClick


•  A procedure is a group of statements designed to perform a specific task.  A procedure attached to an object, such as a button, is a command used to make something happen, e.g.  

   PublicSub Command2_Click()
        Text1.Text=“Thisisaprocedure.”
   EndSub
