Your class, derived from IPropertyNotifySinkCP.


A class that manages the connections between a connection point and its sinks. The default value is CComDynamicUnkArray, which allows unlimited connections. You can also use CComUnkArray, which specifies a fixed number of connections.

The IPropertyNotifySink interface allows a sink object to receive notifications about property changes. Class IPropertyNotifySinkCP exposes this interface as an outgoing interface on a connectable object. The client must implement the IPropertyNotifySink methods on the sink.

Derive your class from IPropertyNotifySinkCP when you want to create a connection point that represents the IPropertyNotifySink interface.
