Замечания

The definition of an information event is that it is a message important enough to always be displayed to most users. It differs from a warning in that no potential damage is implied, and it differs from logging in that it cannot be turned off or filtered and in that it can be handled by event handler.

Because firing of an event may be expensive, the run-time engine provides a mechanism for suppressing events that you are not interested in. Every event firing method has a FireAgain parameter. If the value of this variable is false, after the method returns, the caller will not fire this event again for the duration of the current execution.

Several of the events have a subComponent parameter that allows for even greater granularity in event source identification.
