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 REFERENCES ========== For more information about how to edit a macro, click the Office Assistant while in the Visual Basic Editor, type "edit a macro" (without the quotation marks), click Search, and then click to view "Edit a macro."
