This class exposes IPropertyNotifySink interface as an outgoing interface on a connectable object.
This class and its members cannot be used in applications that execute in the Windows Runtime.
IPropertyNotifySinkCP inherits all methods through its base class, IConnectionPointImpl.
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.
For more information about using connection points in ATL, see the article Connection Points.
