Hello Experts,
I have a script which is getting hung and not able to proceed to next commandline
Below is the script
$ST = new-object -com schedule.service
$Server = "Server1"
$ST.Connect($server)
$M = $ST.GetFolder("\").GetTask("GWSTSAutoPatch")
It gets hung on $ST.GetFolder("\").GetTask("GWSTSAutoPatch") and wont proceed into next command.
Now , question is  , Can I add a timeout on this? so , that script will wait for few sec and it will proceed if it does not get any response.
Thanks,
-Prashant Girennavar.

You can use a do - until loop

do {$ST.GetFolder("\").GetTask("GWSTSAutoPatch")
Start-sleep 10}
until ($ST.GetFolder("\").GetTask("GWSTSAutoPatch" = some value; $M = $ST.GetFolder("\").GetTask("GWSTSAutoPatch"))

Open in new window



Something like the above, I've not actually tested what you're trying to do though

In the edit below, I simply add a try catch and if do not get a value for M we make it null and proceed.
$ST = new-object -com schedule.service
$Server = "Server1"
$ST.Connect($server)
start-sleep 15
try {
$M = $ST.GetFolder("\").GetTask("GWSTSAutoPatch")
}
catch [Exception] {
$M = $null
 return $_.Exception.Message
}
