title: PowerShell script to display Notification balloon and take action only works in ISE gui, not from commandline
body: <p>I've seen a bunch of closely related posts so I know i'm not alone, but none have given me the answer I'm looking for. Apologies if this has been asked and answered and I couldn't find it.</p>
  
  <p>this script creates a custom notification area balloon, which, if clicked on is meant to open a new IE window to some URL. Works great from the PowerShell ISE GUI that I've been working with it in. Can't get it to work from command-line using any of the options i've seen suggested in other posts. Specifically, <strong>can't get the IE window to open</strong>. The notification appears no problem, but no IE window...?? Tried with:</p>
  
  <ul>
  <li>powershell . script.ps1</li>
  <li>powershell -file script.ps1</li>
  <li>command</li>
  <li>&amp;</li>
  </ul>
  
  <p>etc.</p>
  
  <p>Thoughts?</p>
  
  <p>My script:</p>
  
  <pre><code>#Load the required assemblies
  [void] [System.Reflection.Assembly]::LoadWithPartialName(“System.Windows.Forms”)
  #Remove any registered events related to notifications
  Remove-Event BalloonClicked_event -ea SilentlyContinue
  Unregister-Event -SourceIdentifier BalloonClicked_event -ea silentlycontinue
  Remove-Event BalloonClosed_event -ea SilentlyContinue
  Unregister-Event -SourceIdentifier BalloonClosed_event -ea silentlycontinue
  Remove-Event Disposed -ea SilentlyContinue
  Unregister-Event -SourceIdentifier Disposed -ea silentlycontinue
  
  #Create the notification object
  $notification = New-Object System.Windows.Forms.NotifyIcon 
  #Define various parts of the notification
  $notification.Icon = [System.Drawing.SystemIcons]::Information
  $notification.BalloonTipTitle = “**Reminder**”
  $notification.BalloonTipIcon = “Warning”
  $title = “message to user”
  $notification.BalloonTipText = $title
  
  #Make balloon tip visible when called
  $notification.Visible = $True
  
  ## Register a click event with action to take based on event
  #Balloon message clicked
  register-objectevent $notification BalloonTipClicked BalloonClicked_event -Action {
      Start-Process 'c:\Program Files\Internet Explorer\iexplore.exe' -ArgumentList 'http://someURL.com' -WindowStyle Maximized -Verb Open
      #Get rid of the icon after action is taken
      $notification.Dispose()
      } | Out-Null
  
  #Balloon message closed
  register-objectevent $notification BalloonTipClosed BalloonClosed_event -Action {$notification.Dispose()} | Out-Null
  
  #Call the balloon notification
  $notification.ShowBalloonTip(1000)
  </code></pre>
