com.esri.arcgis.framework
Class AppRef

java.lang.Object
  com.esri.arcgis.framework.AppRef

All Implemented Interfaces:

IApplication, com.esri.arcgis.interop.RemoteObjRef, Serializable

public class AppRef
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IApplication

A reference to the currently running application.

Remarks

If for some reason you can't easily get a reference to the Application object in your code, you can create a new AppRef object. For example, there are cases where you may implement an object that exists within the application framework but there is no way to traverse the application hierarchy from that object. In order to provide developers access to the application object there is a singleton object that provides a pointer to the running application object.

Note you can only use the AppRef object if your code is running inside one of the ArcGIS application processes.

Product Availability

Available with ArcGIS Desktop.

Supported Platforms

Windows

Singleton:

This type is a singleton.

Remarks

To find the Name of an ESRI extension, refer to the following technical document:

ArcGIS Developer Help > Technical Documents > Names and IDs > Extensions

If an extension is registered as a Just-In-Time extension, FindExtensionByName may return nothing. The safest way to get a reference to any extension is to use FindExtensionByCLSID.

                                       AutomationException

Finds an extension by its CLSID.

Description

ExtensionCLSID specifies the unique identifier (UID) of an extension.

Remarks

COM coclasses are identified by a globally unique identifier (GUID). There are two formats for the GUID for a coclass: a class ID (CLSID) and a ProgID. The ProgID is a text alias for a CLSID. The UID coclass can be used to represent the GUID of an extension object. You can set the IUID.Value property to either the CLSID or the ProgID.

To find the CLSID and ProgID of an ESRI extension, refer to the following technical document:

ArcGIS Developer Help > Technical Documents > Names and IDs > Extensions

For your custom extensions, the ProgID is a string composed of the name of your project used to make the extension and the class name of the extension. For example if you have a Visual Basic project called MyCustomExt and there is a class module for your extension called clsMyExtension in that project, then the ProgID for this command would be "MyCustomExt.clsMyExtension". To find the CLSID for this command, you could search the system registry for this ProgID.
