A collection of objects that provide information about a COM add-in registered in the Windows Registry.
Assembly: office (in office.dll)
Use the COMAddIns property of the Application object to return the COMAddIns collection for a Microsoft Office host application. This collection contains all of the COM add-ins that are available to a given Office host application, and the Count property of the COMAddins collection returns the number of available COM add-ins.
Use the Update method of the COMAddins collection to refresh the list of COM add-ins from the Windows Registry.
Use COMAddIns.Item(index), where index is either an ordinal value that returns the COM add-in at that position in the COMAddIns collection, or a String value that represents the ProgID of the specified COM add-in.
