Public Function CanExtend (ExtenderCATID As String, ExtenderName As String, ExtendeeObject As Object) As Boolean

Parameters

ExtenderCATID: String

The CATID for the extender being requested.

ExtenderName: String

The name for the extender being requested.

ExtendeeObject: Object

The Extendee object.

Returns

Boolean

true if the provider can provide an extender for the given object with the specified category and name.

Attributes: DispIdAttribute

Remarks

CanExtend returns whether an extender is available for the given CATID and name for the specified extendee instance. The extender provider may need to inspect the extendee instance to determine whether or not it should provide an extender for it. For example, an extender provider may be chartered to create an "ATLClass" extender to a class object, but only if Class.Language has a value of "C++." The extender provider is expected to do this kind of check in this CanExtend method.
