in reply to Win32 Task Scheduler Monitor

okay, there is much shorter to write, but longer to read docs way, using WMI (Windows Management Instrumentation), MSDN describes details, code and results are as following (just few lines of code! i did not expected to have such short program to do the trick...) : 
use Win32::OLE 'in';
$objcoll = Win32::OLE->GetObject("WinMgmts://servername")->InstancesOf
+("Win32_ScheduledJob");
my @x = qw/
  Caption Command DaysOfMonth DaysOfWeek Description ElapsedTime Insta
+llDate
  InteractWithDesktop JobId JobStatus Name Notify Owner Priority RunRe
+peatedly
  StartTime Status TimeSubmitted UntilTime
/;
for $adsobj (in $objcoll) {
  print ++$i,".===\n",join '', map {"  $_:".($adsobj->{$_}||"")."\n"} 
+@x;
}

    Dear Courage, I wolud love to appreciate for all you have done. After tried the WMI approach, it can get all AT instances, but can't see any instance created by Task Scheduler UI program. However, your MSDN research lights me up. After several search in MSDN, I found COM objects called Task Scheduler API and one sample C++ code. It works on instances created by Task Scheduler UI Program. Then, I found another Perl extension Win32-TaskScheduler, created by Umberto Nicoletti. You can find it at http://taskscheduler.sourceforge.net. I'm not familiar with Perl, COM, OLE, but still tried to build a simple example querying the status of remote machine's Task Scheduler instances. Attached for your reference: Thank you very much!!

      You're right. I forgot to try creating tasks via GUI.
      Anyway, it was good exercise for me to try.

      Best wishes,
