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
