Description

The FindExtension method will get an extension by either its name string or by its CLSID. Using IExtensionManager is not the only way to get a reference to an extension; the IApplication interface has FindExtensionByCLSID and FindExtensionByName methods.

nameOrID is a variant representing the identifier of the extension. This can either be the UID of the extension or the name string.

Remarks

COM coclasses are identified by a globally unique identifier (GUID). There 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 Name, CLSID, and ProgID of an ESRI extension, refer to the following technical document:
