The information in this article applies to:

  • Microsoft PowerPoint 2000

This article was previously published under Q222759

SUMMARY

This article provides a sample Microsoft Visual Basic for Applications macro (Sub procedure) that inserts a media object into a slide show and then places the object in the center of the slide.

NOTE: This macro must be run from an on-screen slide show. You can create an action button to run the macro, or you can change the action settings of another AutoShape, so that it runs the macro when you click on the AutoShape.

Sample Visual Basic Procedure

      Const stringPath = "c:\temp\"

      ' Holds the name of the file.
      Const stringName = "test.avi"

      ' Used to store an object reference to a shape.
      Dim shapeAVI As Shape

      Dim sswShow As SlideShowWindow

      ' Variables to store the slide height and width.
      Dim longSlideHeight As Long
      Dim longSlideWidth As Long

      ' Assign sswShow to the current show.
      Set sswShow = ActivePresentation.SlideShowWindow

      ' Check if they are in slide show.
      If Err.Number <> 0 Then
         MsgBox "This macro must be run from within a slide show. " _
           & "Modify the Action Settings of an object to run this macro." _

      ' Create the object.
      With ActivePresentation.Slides(longSlideNumber).Shapes
         Set shapeAVI = .AddMediaObject(stringPath & stringName, 0, 0)

      End With

      ' Get the slide height and width.
      longSlideHeight = ActivePresentation.PageSetup.SlideHeight
      longSlideWidth = ActivePresentation.PageSetup.SlideWidth

      ' Center the media object horizontally.
      If shapeAVI.Width <= longSlideWidth Then
         shapeAVI.Left = ((longSlideWidth - shapeAVI.Width) \ 2)
      End If

      ' Center the media object vertically.
      If shapeAVI.Height <= longSlideHeight Then
         shapeAVI.Top = ((longSlideHeight - shapeAVI.Height) \ 2)
      End If
