How to display a pop-up message box with PowerShell in a script

1 - Load Assembly

Using WPF (Windows Presentation Framework) provides a better look awith rich-looking UIs. It's better that using the legacy Windows Forms.

Add-Type -AssemblyName PresentationCore,PresentationFramework

This helps to access the classes in the Windows Presentation Framework.

Decide the Button Type to use

$ButtonType = [System.Windows.MessageBoxButton]::YesNo

There are 4 types of button Types :

  • OK
  • OKCancel
  • YesNo
  • YesNoCancel

Define the Message Body to display

$MessageBody = "Are you sure you want to delete the log file ?"

No specific info about this, ti's just a string to display. Note that the [String] may contain variables.

Define the message Title

$MessageTitle = "Confirm Deletion"

No specific info about this, ti's just a string to display. Note that the [String] may contain variables.

and finally display the result

$Result = [System.Windows.MessageBox]::Show($MessageBody,$MessageTitle,$ButtonType,$MessageIcon)

As you can show, the Show Method has 4 parameters :

  • MessageBody
  • MessageTitle
  • ButtonType
  • MessageIcon

Note that you must respect this order.

Assemble all code

$var = "John"
Add-Type -AssemblyName PresentationCore,PresentationFramework
$ButtonType = [System.Windows.MessageBoxButton]::YesNoCancel
$MessageIcon = [System.Windows.MessageBoxImage]::Error
$MessageBody = "Are you sure you want to delete the log file, $var"
$MessageTitle = "Confirm Deletion, $Var"
$Result = [System.Windows.MessageBox]::Show($MessageBody,$MessageTitle,$ButtonType,$MessageIcon)
Write-Host "Your choice is $Result"

Additional explanations

  • If you would like to display a Message Info Box, in a scheduled Task script, assure the "Run Only when user is logged on" radio button is selected. Choosing the alternative (i.e. "Run whether user is logged on or not") will hide the script, including any message boxes you have programmed in.
