Answer 1

TEventLogger uses the older ReportEvent() API for logging messages. For that API, you have to register a custom log file and its supported event source names, event types, etc in the Registry. Then you can create TEventLogger using your registered event source name, and messages will go to your registered log file.

This is all documented on MSDN.
