Display Message Box Dialog

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
}
