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
