SUMMARY

This article provides sample Microsoft Visual Basic for Applications code that detects when a slide show has ended. At the end of the slide show, the procedure displays a message indicating that the show is over.

This Visual Basic example does not handle error trapping in the following cases:

  • PowerPoint is not running.
  • A presentation is not open.

Sample Visual Basic Procedure

     Sub SlideShowStatus()

      ' Enable error trapping.
      On Error Resume Next
      Err.Clear

      Dim ppt As Object

      ' Get an object reference to PowerPoint. This code
      ' assumes PowerPoint is running. If PowerPoint is not
      ' running, the Err object gets set.
      Set ppt = GetObject(, "PowerPoint.Application.8")

      ' Check if an error occurred when running GetObject.
      If Err.Number <> 0 Then
         MsgBox "PowerPoint is not running. Start PowerPoint, open a " _
            & "presentation, and run the code again."
         End
      End If

      ' Starts a slide show. This code assumes a presentation
      ' is open. If a presentation is not running the Err object
      ' is set.
      ppt.ActivePresentation.SlideShowSettings.Run

      ' Check if an error occurred when running GetObject.
      If Err.Number <> 0 Then
         MsgBox "A presentation is not open. Open a presentation and " _
            & "run the code again."
         End
      End If

      ' This loop checks to see if the slide show has ended. When the
      ' code sets the Err object, the slide show is ended.
      Do
         DoEvents
      Loop Until ppt.SlideShowWindows(1).View.State = ppSlideShowDone

      ' Check if the slide show has ended.
      If Err.Number = 0 Then

         ' The slide show did not end. The code should never
         ' flow here.
         MsgBox "Slide Show did not end!"
         End

      Else

        ' The slide show has ended.
        '
        ' NOTE: If you are running this code from a control on a form,
        ' you should give focus back to your form (Form1.GetFocus) here.
        MsgBox "SLIDE SHOW DONE!"

      End If

   End Sub
