使用VBA将数据从Microsoft Excel中的Microsoft Excel中获取数据

Question

我想从使用VBA的Excel（将数据粘贴到Powerpoint图形对象后面的数据表中）中将数据转换为Excel中的Powerpoint图形。

我使用这个代码为例（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 

当我运行这个PPT打开就好了，然后代码在停止：

Set oGraph = oPPTShape.OLEFormat.Object 

与错误消息“OLEFormat（未知成员）：请求无效，此属性仅适用于OLE对象。”

我使用Excel和PowerPoint 2010中

我在做什么错？我对这一切都很陌生，所以我认为这很简单。

谢谢

在PowerPoint 2010中做事情的新方法是创建一个Excel工作表，并将其链接到图表的ChartData。

如何做到这一点的一个例子在http://msdn.microsoft.com/en-us/library/ff973127.aspx给出，为方便起见在下面转载。

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
