使用VBA從Microsoft Excel獲取數據到Powerpoint圖

Question

我正在嘗試使用VBA從Excel中將數據導入Powerpoint圖形（將數據粘貼到Powerpoint圖形對象后面的數據表中）。

我正在使用此代碼作為示例（ 源代碼 ）：

'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

當我運行它時，PPT打開就好了，然后代碼停在：

Set oGraph = oPPTShape.OLEFormat.Object

錯誤消息“OLEFormat（未知成員）：無效請求。此屬性僅適用於OLE對象。”

我正在使用Excel和PowerPoint 2010。

我究竟做錯了什么？ 我對這一切都很陌生，所以我認為這很簡單。

謝謝

在PowerPoint 2010中執行的新方法是創建Excel工作表並將其鏈接到圖表的ChartData 。

有關如何執行此操作的示例，請參閱http://msdn.microsoft.com/en-us/library/ff973127.aspx，並在下方轉載以方便使用。

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
