CronJob

The CronJob Delphi component was designed to be a thread-based alarm implementation for Delphi/BCB which acts like cronjob utility in Unix.
The component produces periodical OnAlert events by schedule specified in CRON format (actually it uses extended CRON format with new "seconds" field, to let the event to be triggered even every second).
The package includes 2 bonus components:
ï¿­ AccurateTimer - thread-based timer which periodically triggers the OnTimer events by specified Interval, but unlike standard TTimer, which based on Win32API and thus loses timer messages on high application overload, this timer runs in the separate thread and accurately triggers each OnTimer event at right time. It also allows to specify the Interval with higher precision (less than 55msec, limited in Win9x) and does not dependent to the system-wide limitations.)
ï¿­ AwayTimer - monitors user activity and increase its time counter when keyboard and mouse are inactive (user distracted from PC or goes away). Also it triggers special event when system is about to start the screensaver, or after some defined period of user inactivity
Limitations:
ï¿­ You can try it out for free, but if you like it and want to use it you have to register it with the author.
Requirements:
ï¿­ Delphi 2/3/4/5/6/7/2005 and BCB 1/3/4/5/6
