NOTE: The following macro examples work only in PowerPoint. Visual Basic for Applications macros are not supported by the Microsoft PowerPoint Viewer. For additional information, click the following article number to view the article in the Microsoft Knowledge Base: Before you can run the sample Visual Basic macro, you must add a reference to the Microsoft Excel 9.0 object library model. To add the reference:
 * 1) On the Tools menu, point to Macro, 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 Excel 9.0 Object Library check box.
 * 4) Click OK.

You now have a reference (in this project) to the Graph 9.0 object model.

Sample Visual Basic for Applications 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 Excel linked OLE object. If oShape.Type = msoLinkedOLEObject Then

' Check whether the OLE object is a Chart or a Sheet object. If oShape.OLEFormat.ProgID = "Excel.Chart.9" _ Or oShape.OLEFormat.ProgID = "Excel.Sheet.9" Then

' Found a Chart; obtain object reference, and ' then update. Set oGraph = oShape.OLEFormat.Object oGraph.Application.Update

End If           End If         Next oShape Next oSlide

End Sub
