ITypeChangeEvents interface

Enables clients to subscribe to type change notifications on objects that implement the ITypeInfo, ITypeInfo2, ICreateTypeInfo, and ICreateTypeInfo2 interfaces. When ITypeChangeEvents is implemented on an object, it acts as an incoming interface that enables the object to receive calls from external clients and engage in bidirectional communication with those clients. For more information, see Events in COM and Connectable Objects.
