The event logging system

All important steps during the program startup and the activities of all print channels are logged in the logging panel on the right main control screen.
Concurrently all lines are stored in a log-file to allow later reviews.A simple filter dialogue can help tracing possible error messages or selecting a
certain time frame:

NOTE: Do not open the log-file with write access, like some editors do per default, while the AutoPrint application or service is active. This could cause conflicts since AutoPrint frequently attempts to update the file.

NOTE: The log file will grow to up to 100,000 lines over time. AutoPrint starts trimming the file by 10% once this value is reached.

NOTE: The message types to be shown and recorded in the log-file, can be set in the Settings > Event handling form. The maximum of information is provided after activating the Debug modus on the Setup > System form. The message type selection is valid for all print channels.

NOTE: The new table format is also used in the body of the optional email reports generated by AutoPrint.

Starting with AutoPrint version 8.14 the event logging storage has been moved from the settings database AutoPrint.db to a local text file: AutoPrint.log
The file is located in the hidden Windows data folder C:\ProgramData\AutoPrint8, unless the user has changed this default location.
The file AutoPrintService.log, which was previously managed exclusively by the AutoPrint service, is no longer used.

This change not only improves the overall program stability, but also allows programmers to implement their own after-print-job processes by analyzing this file.
For this purpose all recorded events are being cast into a static table format, shown in the following figure:
