IApplication Interface

Provides access to members that query or modify the application.

Product Availability

Available with ArcGIS Desktop.

Description

The Application object is the core object in the ArcMap and ArcCatalog applications. This object represents the application itself and acts as the central point where access is gained to other objects in the system. The Application object's primary interface is IApplication. This interface provides access to the Document object, the extensions, the StatusBar object, the Templates object, the currently selected tool, and the Visual Basic Editor. There are several methods that allow you to open, save, and print documents, lock and unlock the application from user customizations, display dialogs, and exit the application.
