使用 VBA 从 Microsoft Excel 将数据导入 Powerpoint 图表

Question

我正在尝试使用 VBA 从 Excel 将数据导入 Powerpoint 图表（将数据粘贴到 Powerpoint 图表对象后面的数据表中）。

我以这段代码为例（source）：

'Code by Mahipal Padigela
'Open Microsoft Powerpoint,Choose/Insert a Graph type Slide(No.8), then double click to add a graph and click...
'...outside the graph to close the Datasheet, then rename the Graph to "Mychart",Save and Close the Presentation
'Open Microsoft Excel, add some test data to Sheet1(This example assumes that you have some test data...
'...(numbers between 0-100) in Rows 2,3,4 and Columns B,C,D,E).
'Open VBA editor(Alt+F11),Insert a Module and Paste the following code in to the code window
'Reference 'Microsoft Powerpoint Object Library' (VBA IDE-->tools-->references)
'Reference 'Microsoft Graph Object Library' (VBA IDE-->tools-->references)
'Change "strPresPath" with full path of the Powerpoint Presentation created earlier.
'Change "strNewPresPath" to where you want to save the new Presnetation to be created later
'Close VB Editor and run this Macro from Excel window(Alt+F8) 

Dim oPPTApp As PowerPoint.Application
Dim oPPTShape As PowerPoint.Shape
Dim oPPTFile As PowerPoint.Presentation
Public oGraph As Graph.Chart
Dim SlideNum As Integer

Sub PPGraphMacro()
    Dim strPresPath As String, strExcelFilePath As String, strNewPresPath As String
    strPresPath = "H:\PowerPoint\Presentation1.ppt"
    strNewPresPath = "H:\PowerPoint\New1.ppt"

    Set oPPTApp = CreateObject("PowerPoint.Application")
    oPPTApp.Visible = msoTrue
    Set oPPTFile = oPPTApp.Presentations.Open(strPresPath)
    SlideNum = 1
    oPPTFile.Slides(SlideNum).Select
    Set oPPTShape = oPPTFile.Slides(SlideNum).Shapes("Mychart")
    Set oGraph = oPPTShape.OLEFormat.Object

    Sheets("Sheet1").Activate
    oGraph.Application.DataSheet.Range("A1").Value = Cells(2, 2).Value
    oGraph.Application.DataSheet.Range("A2").Value = Cells(3, 2).Value
    oGraph.Application.DataSheet.Range("A3").Value = Cells(4, 2).Value
    oGraph.Application.DataSheet.Range("B1").Value = Cells(2, 3).Value
    oGraph.Application.DataSheet.Range("B2").Value = Cells(3, 3).Value
    oGraph.Application.DataSheet.Range("B3").Value = Cells(4, 3).Value
    oGraph.Application.DataSheet.Range("C1").Value = Cells(2, 4).Value
    oGraph.Application.DataSheet.Range("C2").Value = Cells(3, 4).Value
    oGraph.Application.DataSheet.Range("C3").Value = Cells(4, 4).Value
    oGraph.Application.DataSheet.Range("D1").Value = Cells(2, 5).Value
    oGraph.Application.DataSheet.Range("D2").Value = Cells(3, 5).Value
    oGraph.Application.DataSheet.Range("D3").Value = Cells(4, 5).Value


    oGraph.Application.Update
    oGraph.Application.Quit

    oPPTFile.SaveAs strNewPresPath
    oPPTFile.Close
    oPPTApp.Quit

    Set oGraph = Nothing
    Set oPPTShape = Nothing
    Set oPPTFile = Nothing
    Set oPPTApp = Nothing
    MsgBox "Presentation Created", vbOKOnly + vbInformation
End Sub

当我运行它时，PPT 会正常打开，然后代码会停在：

Set oGraph = oPPTShape.OLEFormat.Object

带有错误消息“OLEFormat（未知成员）：无效请求。此属性仅适用于 OLE 对象。”

我正在使用 Excel 和 PowerPoint 2010。

我做错了什么？我对这一切都很陌生，所以我认为这很简单。

谢谢

PowerPoint 2010 中的新处理方式是创建一个 Excel 工作表并将其链接到图表的 ChartData。

http://msdn.microsoft.com/en-us/library/ff973127.aspx 提供了如何执行此操作的示例，为方便起见，请在下面复制。

Sub CreateChart()
    Dim myChart As Chart
    Dim gChartData As ChartData
    Dim gWorkBook As Excel.Workbook
    Dim gWorkSheet As Excel.Worksheet

    ' Create the chart and set a reference to the chart data.
    Set myChart = ActivePresentation.Slides(1).Shapes.AddChart.Chart
    Set gChartData = myChart.ChartData

    ' Set the Workbook and Worksheet references.
    Set gWorkBook = gChartData.Workbook
    Set gWorkSheet = gWorkBook.Worksheets(1)

    ' Add the data to the workbook.
    gWorkSheet.ListObjects("Table1").Resize gWorkSheet.Range("A1:B5")
    gWorkSheet.Range("Table1[[#Headers],[Series 1]]").Value = "Items"
    gWorkSheet.Range("A2").Value = "Coffee"
    gWorkSheet.Range("A3").Value = "Soda"
    gWorkSheet.Range("A4").Value = "Tea"
    gWorkSheet.Range("A5").Value = "Water"
    gWorkSheet.Range("B2").Value = "1000"
    gWorkSheet.Range("B3").Value = "2500"
    gWorkSheet.Range("B4").Value = "4000"
    gWorkSheet.Range("B5").Value = "3000"

    ' Apply styles to the chart.
    With myChart
        .ChartStyle = 4
        .ApplyLayout 4
        .ClearToMatchStyle
    End With

    ' Add the axis title.
    With myChart.Axes(xlValue)
        .HasTitle = True
        .AxisTitle.Text = "Units"
    End With

    'myChart.ApplyDataLabels

    ' Clean up the references.
    Set gWorkSheet = Nothing
    ' gWorkBook.Application.Quit
    Set gWorkBook = Nothing
    Set gChartData = Nothing
    Set myChart = Nothing

End Sub
