application. Visual Basic for Applications macros are not supported by the
Microsoft PowerPoint Viewer. For additional information, please see the
following article in the Microsoft Knowledge Base:

  Q230746 PPT: Viewer: Presentation Macros Don't Run Within the Viewer

Before you can run the sample Visual Basic macro, you must add a reference to the
Graph 8.0 object model. To add the reference, follow these steps:

1. On the Tools menu, point to Macros, and then click Visual Basic Editor.

2. On the Tools menu, click References.

3. In the References - VBAProject dialog box, click to select the Microsoft
  Graph 8.0 Object Library check box.

4. Click OK.

  The project now contains a reference to the Graph 8.0 object model.

Sample Visual Basic Procedure
-----------------------------

  Sub UpdateAllGraphs()

     Dim oShape As Shape
     Dim oSlide As Slide
     Dim oGraph As Object
     '
     ' Loop through each slide in the presentation.
     '
     For Each oSlide In ActivePresentation.Slides
     '
     ' Loop through all the shapes on the current slide.
     '
        For Each oShape In oSlide.Shapes
     '
     ' Check whether the shape is an OLE object.
     '
           If oShape.Type = msoEmbeddedOLEObject Then
     '
     ' Check whether the OLE object is a Graph 8 object.
     '
              If oShape.OLEFormat.ProgID = "MSGraph.Chart.8" Then
     '
     ' Found a graph; obtain object reference, and
     ' then update.
     '
                 Set oGraph = oShape.OLEFormat.Object
                 oGraph.Application.Update
     '
     ' Now, quit out of the MSGraph program. This frees 
     ' memory, and prevents any problems. Also, set oGraph equal
     ' to Nothing to release the object.
     '
                 oGraph.Application.Quit
                 Set oGraph = Nothing
              End If
           End If
        Next oShape
     Next oSlide

  End Sub
