kambe has asked for the wisdom of the Perl Monks concerning the following question:
I am trying to use Win32::OLE to create a task on a Windows 10 system, something similar to href:https://onedrive.live.com/?authkey=%21ABowWrIzVQzcElo&cid=07CD1B37769E1B7D&id=7CD1B37769E1B7D%21102691&parId=7CD1B37769E1B7D%21102690&o=OneUp. I tried to manually validate the query by creating the same task by hand in the task scheduler GUI, and that seemed to work.
Here's my test code:
use File::Basename; use Win32; use Win32::OLE; $Win32::OLE::Warn = 3; use Data::Dumper; my ($me, $dirpath, $suffix) = fileparse($0, qr/\.[^.]*/); my ($system, $login, $domain, $sidbin, $sidtype, $sidtxt) = ""; $login = Win32::LoginName(); Win32::LookupAccountName($system, $login, $domain, $sidbin, $sidtype); my($Revision, $SubAuthorityCount,@IdentifierAuthorities) = unpack("CCn +nn", $sidbin); unless (($IdentifierAuthorities[0] || $IdentifierAuthorities[1])) { my($temp, $temp2, @SubAuthorities) = unpack("VVV$SubAuthorityCount +",$sidbin); $sidtxt = "S-$Revision-$IdentifierAuthorities[2]-".join("-",@SubAu +thorities); } die Win32::OLE->LastError() unless (my $service = Win32::OLE->CreateOb +ject('Schedule.Service')); $service->Connect; my $RootFolder = $service->GetFolder('\\'); die Win32::OLE->LastError() unless (my $TaskDefinition = $service->New +Task(0)); die Win32::OLE->LastError() unless (my $regInfo = $TaskDefinition->Reg +istrationInfo); $regInfo->{Description} = "Register a perl task as an event $me"; $regInfo->{Author} = "$domain\\$login"; $regInfo->{URI} = "$sidtxt\\$me"; die Win32::OLE->LastError() unless (my $settings = $TaskDefinition->Se +ttings); $settings->{Enabled} = 1; $settings->{AllowDemandStart} = 1; $settings->{DisallowStartIfOnBatteries} = 0; $settings->{StopIfGoingOnBatteries} = 0; $settings->{Hidden} = 0; my @Triggers; my $TriggerSet; die Win32::OLE->LastError() unless ($TriggerSet = $TaskDefinition->Tri +ggers); for (10000..10001) { die Win32::OLE->LastError() unless (push @Triggers, $TriggerSet->C +reate(0)); $Triggers[$#Triggers]->{Id} = $_; $Triggers[$#Triggers]->{Subscription} = "<QueryList> <Query Id=\"event$_\" Path=\"Microsoft-Windows-NetworkProfile/Operat +ional\"> <Select Path=\"Microsoft-Windows-NetworkProfile/Operational\">*[Sy +stem[(EventID=\"$_\")]]</Select> </Query> </QueryList>"; die Win32::OLE->LastError() unless (my $values = $Triggers[$#Triggers]->ValueQueries->Create +("eventId", "Event/System/EventID")); $Triggers[$#Triggers]->{Enabled} = 1; } die Win32::OLE->LastError() unless (my $Action = $TaskDefinition->Acti +ons()->Create(0)); $Action->{Path} = 'C:\Perl64\Bin\Perl.exe'; $Action->{Arguments} = "$0 -f event\${eventID}"; $RootFolder->RegisterTaskDefinition("OLE-Test",$TaskDefinition,6,undef +,undef,3); print Dumper $TaskDefinition->{XmlText};
If I run the code with RegisterTaskDefinition with TASK_VALIDATE_ONLY flag set (third parameter = 1), I get a nice XML dump. So far so good. When I run the code with RegisterTaskDefinition with TASK_CREATE_OR_UPDATE (third parameter = 6), I get this error:
OLE exception from "<Unknown Source>": (11,263):Subscription:<QueryList><Query Id="event10000" Path="Microsoft-Windows-NetworkProfile/Operational"><Select Path="Microsoft-Windows-NetworkProfile/Operational">*[System[(EventID= +"10000")]]</Select></Query></QueryList> Win32::OLE(0.1712) error 0x80073a99: "The specified query is invalid" in METHOD/PROPERTYGET "RegisterTaskDefinition" at OLE-test.pl line + 63.
Anyone familiar enough with Win32::OLE, and the Windows task scheduler XML to explain what I'm doing wrong
