Understanding the Publisher Application Object
Use properties or methods of the Application object to control or return the Microsoft® Publisher application-wide attributes, to control the appearance of the application window, and to get to the rest of the Publisher object model. In addition, COM add-ins can attach to the Application object.
Every time you write Microsoft® Visual Basic® for Applications (VBA) code in Publisher or write code to automate Publisher from some other application, you begin with the Application object. From the Application object, you can access all the other objects exposed by the application, as well as properties and methods unique to the Application object itself.
