Hi,

I'd really like to be able to have my recipe calculate a date/time in the
future, then create a task via schtasks, because I think I can use this type
of approach for several different situations, but I'm kind of stuck figuring
out how to parameterize the schtasks creation.

I think that I've figured out the code to calculate the future date and time,
and even put the date and time into some vars formatted the way that schtasks
wants them, but I am kind of baffled about how to actually use those two vars
($mydate and $mytime) in the schtasks command.

Here's what I have:

$future_time = $(Get-Date).AddMinutes(15)

echo "Future time is: " $future_time >> c:/install-SHAREPOINT2007FULL.log

$mydate = $future_time.ToString("MM/dd/yyyy")
$mytime = $future_time.ToString("HH:MM")

schtasks /create /tn Task_Name /tr "chef-client -o
install-SHAREPOINT2007FULL-PART2" /sc once /RU "env2\\Administrator" /RP
"xxxxx" /RL HIGHEST /SD $mydate /ST $mytime

I think the problem is that the two vars are not being expanded or something
like that, but I can't figure out what the correct syntax is for doing that.
I've tried double-quoting the vars (e.g., "$mydate") and putting them inside
parens (e.g., $($mydate), and other variants, but keep getting an error
saying that the date is less than current or something like that.

I know that this is getting a little off-topic, but if anyone knows how to
set that schtasks with the two vars, can you please post?

Thanks!

Jim

You may create the task with no
schedule and add a registry entry in a run_once to trigger
the task.

See
http://stackoverflow.com/questions/290559/how-do-i-stop-start-a-scheduled-task-on-a-remote-computer-programatically
for exemple,  locally you can omit the machine
Switch or use a dot to target the local machine.
