The AddIns collection contains references to AddIn objects and is accessed directly from the root VBE object. Every add-in listed in the Add-In Manager dialog box in an instance of Visual Basic has an AddIn object in this collection. The AddIn object provides information about an add-in to other add-ins.
Using the AddIns collection and AddIn object, you can manipulate add-ins — connect and disconnect them programmatically, add or remove them with the Update method, and so forth.
For More Information For information on using the rest of the objects in the extensibility object model to create and use add-ins, see "Programming in the Extensibility Model."
