PowerShell is console-based, but sometimes it would be nice to add some simple dialogs. Here is a function called Show-MessageBox that can display all kinds of standard message boxes and comes with IntelliSense for parameters:
#requires -Version 2 Add-Type -AssemblyName PresentationFramework function Show-MessageBox { param ( [Parameter(Mandatory=$true)] $Prompt, $Title = 'Windows PowerShell', [Windows.MessageBoxButton] $Buttons = 'YesNo', [Windows.MessageBoxImage] $Icon = 'Information' ) [System.Windows.MessageBox]::Show($Prompt, $Title, $Buttons, $Icon) } $result = Show-MessageBox -Prompt 'Rebooting.' -Buttons OKCancel -Icon Exclamation if ($result -eq 'OK') { Restart-Computer -Force -WhatIf }
