SUMMARY

Microsoft PowerPoint has a Custom Show feature that allows you to show some of the slides in a presentation as a slide show or to reorder the slides when you run a slide show.

This article contains a sample Microsoft Visual Basic for Applications macro (Sub procedure) that creates a custom show. The macro creates a custom show that includes every slide in the active presentation. You can modify the code to select specific slides to be a part of your custom show.

Sample Visual Basic Procedure

Sub CreateCustomShow()

   On Error Resume Next

   'Change this value to the name you want to use for your
   'custom slide show.
   Const strDefaultName As String = "My Custom Show"

   Dim lNumSlides, lSlideList(), lCount As Long
   Dim oSlide As Slide
   Dim strPrompt, strShowName As String
   Dim Continue As Boolean: Continue = False

   'Get the number of slides in the active presentation.
   lNumSlides = ActivePresentation.Slides.Count

   'Make sure at least 1 slide is in the presentation.
   If lNumSlides < 1 Then
     MsgBox "No slides in the presentation.", vbExclamation, "No Slides"
     End
   End If

   'Initialize the counter.
   lCount = 0

   'Loop through the slides in the presentation.
   For Each oSlide In ActivePresentation.Slides

      'Make the array one element larger.
      ReDim Preserve lSlideList(lCount)

      'Add the slide id to the array.
      lSlideList(lCount) = oSlide.SlideID

      'Increment the counter.
      lCount = lCount + 1

   Next oSlide

   'Reset the counter
   lCount = 0

   'Set the name of the custom show to the default.
   strShowName = strDefaultName

   'Loop until a custom show is created.
   Do

      'Increment the counter.
      lCount = lCount + 1

      With ActivePresentation.SlideShowSettings.NamedSlideShows

         'Clear the error object.
         Err.Clear

         'Create the custom show.
         .Add strShowName, lSlideList

         'Check to see if an error occurred creating the show.
         'A run-time error occurs if the custom show name you specify
         'is already being used.
         If Err.Number <> 0 Then

            'Change the name of the custom show
            strShowName = strDefaultName & " " & CStr(lCount)
         Else
            Continue = True
         End If

      End With

   Loop While Continue = False

   'Create and then display message box.
   strPrompt = "Successfully created custom show named " & strShowName _
    & ". To view the show:" & Chr(13) & Chr(13) _
    & Chr(9) _
    & "1. On the Slide Show menu, click Custom Shows." _
    & Chr(13) & Chr(9) _
    & "2. Highlight the custom show you want to run." _
    & Chr(13) & Chr(9) _
    & "3. Click the show button to run the show." _
    & Chr(13) & Chr(13) _
    & "NOTE: If the Custom Shows dialog box is visible " _
    & "when you run this macro. Close and" _
    & Chr(13) _
    & "then reopen the dialog box to see the updated custom show list."
   MsgBox strPrompt, vbInformation, "Custom Show Created!"

End Sub
