Sample Visual Basic Procedure

   Sub CountGraphs()

      ' Dimension the variables.
      Dim shapeObject As Shape
      Dim lSlideNumber As Long
      Dim lCount As Long
      Dim strPrompt As String
      Dim strTitle As String
      Dim lBoxStyle As Long

      ' Make sure PowerPoint is using normal view.
      If ActiveWindow.ViewType <> ppViewNormal Then

         MsgBox "You must be in slide view to run this macro."
         End

      End If

      ' Initialize the counter.
      lCount = 0

      ' Get the current slide number.
      lSlideNumber = ActiveWindow.Selection.SlideRange.SlideNumber

      ' Look at all shapes on the current slide.
      For Each shapeObject In _
         ActivePresentation.Slides(lSlideNumber).Shapes

         ' Check to see whether shape is an OLE object.
         If shapeObject.Type = msoEmbeddedOLEObject Then

            ' Check to see whether OLE object is Graph 8 object. The ProgID
            ' is case sensitive.
            If shapeObject.OLEFormat.ProgID = "MSGraph.Chart.8" Then

               ' Found a graph; add 1 to the total.
               lCount = lCount + 1
            End If

         End If

      Next shapeObject

      ' Creates and then displays the message box.

      ' Set the message box style.
      lBoxStyle = vbInformation

      Select Case lCount

         ' No graphs were found.
         Case 0
            strPrompt = "No graphs were found on the slide."
            strTitle = "No graphs"

         ' One graph was found.
         Case 1
            strPrompt = "One graph was found on the slide."
            strTitle = "One Graph"

         ' More than one graph was found.
         Case Is > 1
            strPrompt = lCount & " Graphs were found on the slide."
            strTitle = lCount & " Graphs"

         ' An error occurred.
         Case Else
            strPrompt = "An error occurred!"
            strTitle = "Error"
            lBoxStyle = vbCritical
      End Select

      'Display the message box.
      MsgBox strPrompt, lBoxStyle, strTitle

   End Sub
