Show_GUIForm from ps1 script without waiting for the GUIForm to close...

[MikePro85]

Hello

I have a ps1 script running (no GUI) but need to open a GUI window from it. The ps1 script however has to continue running and not wait until the GUI form window is closed.

Usually I use the Show-Form_psf command, but if I use that, the powershell script in the background stops/waits until the window has been closed.

You could launch your window using a runspace.

Code: [Select all] [Expand/Collapse] [Download] (Untitled.ps1)

1. [int]$Counter = 1
2. if($counter -lt 5000){
3.     $counter++
4.     Start-Sleep -Seconds 3    
5. }
6.  
7. $RunSpace = [RunSpaceFactory]::CreateRunSpace() #Create new runspace.
8. $RunSpace.ApartmentState = 'STA'
9. $RunSpace.ThreadOptions = 'UseNewThread'
10. $RunSpace.Open()
11. $Instance = [PowerShell]::Create() #create new powershell instance in runspace.
12. $Instance.Runspace = $RunSpace
13. $Instance.Runspace.SessionStateProxy.SetVariable("Counter", $Counter) #pass $Counter variable into runspace
14. [void]$Instance.AddScript({
15.     if($counter = 2500){                
16.         #displays first messagebox while script continues counting in background.
17.         [System.Windows.Forms.MessageBox]::Show("Count = " + $counter + " Almost Done!")
18.     }
19.     $Instance.EndInvoke()            
20.     $Instance.Dispose()
21.     $RunSpace.Close()            
22. }).BeginInvoke()
23.  
24. if($counter = 5000){
25.     Start-Sleep -Seconds 3
26.     [System.Windows.Forms.MessageBox]::Show("Count = " + $counter + " Job Complete!")
27. }
