I discovered the answer to my own question and I'll answer it here in case someone else needs to do the same thing. I was expecting to add properties and methods by selecting the class in the ClassView and right clicking for the popup menu, but you can only add class member variables and functions. To add methods and properties to any interfaces in your classes, you need to find and select the application's type library listed in the ClassView. It is represented by a gray rectangle with rounded corners with a node extruding from the left side. If you expand the library, you will see a list of interfaces that exist in your project. Select the appropriate interface, right click, and add your methods and properties. I hope this helps someone else. Kind regards, Tim
