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:
- On the Tools menu, point to Macros, and then click Visual Basic Editor.
- On the Tools menu, click References.
- In the References - VBAProject dialog box, click to select the Microsoft Graph 8.0 Object Library check box.
- 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
