TObject |
TEventLog is a component which can be used to send messages to the system log. In case no system log exists (such as on Windows 95/98 or DOS), the messages are written to a file. Messages can be logged using the general Log call, or the specialized Warning, Error, Info or Debug calls, which have the event type predefined.
