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." _
           , vbCritical, "Assign Macro to a Button"
         End
      End If

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

      ' Set the play settings for the movie.

         .PlaySettings.PlayOnEntry = msoTrue
         .AdvanceMode = ppAdvanceOnTime
         .AdvanceTime = 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.
