Raising an event invokes the event handler through a delegate. The Synchronizing property must be set.
The OnLog method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Note to Inheritors: When overriding OnLog in a derived class, be sure to call the base class OnLog method, so that registered delegates receive the event.
See the SynchronizingObject property for important information on updating UI controls from within derived classes and events.
