Creating Object Properties

The Property Set procedure behaves the same as the Property Let procedure, except that you use it to assign an object reference to an object property. You can then use a corresponding Property Get procedure to return the object reference.

There are a couple of cases in which it is useful to create an object property. When you want to create a new object that provides all the properties, methods, and events of an existing object, plus additional ones that you have defined, you can create an object property that returns a reference to the existing object. In addition, when you create an object model that has a hierarchy — the object contains other objects or collections — you must create an object property to access a lower-level object in the hierarchy.
