我有一大堆图表我在Excel中，我想更新到现有的功率点。
为此，我找到了以下优秀代码：
http://www.myengineeringworld.net/2012/11/export-all-excel-charts-to-power-point.html
其中有魅力。现在，我需要简单地打开现有的功率点并添加图形（而不是新图形），我还想将图形作为链接图表发布。
这是原始代码：

Next ws

首先，我无法弄清楚如何更改这部分代码：
'Open PowerPoint and create a new presentation.
Set pptApp = New PowerPoint.Application
Set pptPres = pptApp.Presentations.Add
所以我只是打开现有的演示文稿，我已经尝试了很多变种
Set pptApp = New PowerPoint.Application
pptApp.Visible = True
pptApp.Presentations.Open("filelocation.pptx")
还有更多，但我似乎无法让系统捕获已经打开的电源点文件，或只是直接从链接打开它。
这也导致我无法将图表链接到Excel工作表，因此当我更改数字时，它们也会发生变化。
我似乎正在努力分配对象的正确方法？
答案 0 :(得分：1)
我创建了一个代码，您可以使用FileDialog命令选择现有的PowerPoint。 在选择要更新的PowerPoint文件后，它将转到所选幻灯片，删除所有现有的图表对象。 将所有图表对象从Excel中的某个工作表复制到此幻灯片后。
这是我正在使用的一段代码。 首先，您需要致电主要程序。
Public Sub Main()
Dim PowerPoint_Selected As String
PowerPoint_Selected = GetFileName(ActiveWorkbook.Path)
Call UpdatePowerPoint(PowerPoint_Selected)
End Sub
这是让您选择要更新的PowerPoint幻灯片的功能。
Public Function GetFileName(strPath As String) As String
Dim fDialog As FileDialog
Dim result As Integer
Dim FileSelected As String
Set fDialog = Application.FileDialog(msoFileDialogFilePicker)
'Optional: FileDialog properties
fDialog.AllowMultiSelect = False
fDialog.Title = "Select a file"
fDialog.InitialFileName = strPath
'Optional: Add filters
fDialog.Filters.Clear
fDialog.Filters.Add "PowerPoint files", "*.ppt*"
'Show the dialog. -1 means success!
If fDialog.Show = -1 Then
GetFileName = fDialog.SelectedItems(1)
End If
If GetFileName = "" Then
MsgBox "No PowerPoint file was selected !", vbExclamation, "Warning"
End
End If
End Function
这是更新要更新的PowerPoint幻灯片中所有图表的例程。将SlideNum变量中的值更新为您要使用的任何幻灯片。
Public Sub UpdatePowerPoint(PowerPointFile)
'Add a reference to the Microsoft PowerPoint Library by:

'2. Click on Reference
'3. Scroll down to Microsoft PowerPoint X.0 Object Library, check the box, and press Okay
