I'm trying to implement a GUI to my PowerShell script to simplify a certain process for other users. I have following PowerShell script:
if ($checkBox1.Checked) {
Try{
Start-Job { & K:\sample\adp.cmd }
$listBox1.Items.Add("ADP-Job started...")
}catch [System.Exception]{
$listBox1.Items.Add("ADP --> .cmd File not found!")}
}
if ($checkBox2.Checked) {
Try{
Start-Job { & K:\sample\kdp.cmd }
$listBox1.Items.Add("KDP-Job started...")
}catch [System.Exception]{
$listBox1.Items.Add("KDP --> .cmd File not found!")}
}
Is there a way to continuously check all running Jobs and do something for each Job that has finished? For Example to print out something like this in my listbox: ADP-Files have been uploaded
Since each Job takes around 5 minutes - 4 hours I thought of a while Loop that checks every 5 minutes if a Job is finished, but I can't figure out how to distinguish each Job to do something specific.
You can either specifiy a name for the job using the -Name
parameter:
Start-Job { Write-Host "hello"} -Name "HelloWriter"
And receive the job status using the Get-Job
cmdlet:
Get-Job -Name HelloWriter
Output:
Id Name PSJobTypeName State HasMoreData Location Command
-- ---- ------------- ----- ----------- -------- -------
3 HelloWriter BackgroundJob Completed True localhost Write-Host "hello"
Or you assign the Start-Job
cmdlet to a variable and use it to retrieve the job:
$worldJob = Start-Job { Write-Host "world"}
So you can just write $woldJob
and receive:
Id Name PSJobTypeName State HasMoreData Location Command
-- ---- ------------- ----- ----------- -------- -------
7 Job7 BackgroundJob Completed True localhost Write-Host "world"
You also don't have to poll the Job state. Instead use the Register-ObjectEvent
cmdlet to get notificated when the job has finished:
$job = Start-Job { Sleep 3; } -Name "HelloJob"
$jobEvent = Register-ObjectEvent $job StateChanged -Action {
Write-Host ('Job #{0} ({1}) complete.' -f $sender.Id, $sender.Name)
$jobEvent | Unregister-Event
}
Multiple possible ways here:
$Var = Start-Job { & K:\sample\kdp.cmd }
an then check
$Var.State
Or give the job a name
Start-Job { & K:\sample\kdp.cmd } -Name MyJob
and then check
Get-Job MyJob
