This method unregisters an application object previously registered for connection start or stop events with the RegisterStartEvent function. A registered application notify object should not be destroyed without first calling this function to unregister it. If there is no notify object currently registered, or the registered object is not the NotifyObject passed in, this function does nothing (no error is thrown).

When a notify object is unregistered, its NotifyStop method is called.

See ECLStartNotify Class for more information.
