Question

我正在尝试编写代码以从excel VBA打开PPTX文件并更新ppt中的链接。

下面是我已经获得的代码，但是当代码尝试更新链接时，我正在获取

运行时错误438对象不支持此属性或方法

Sub kunal()

Dim PPObj As Object

Set PPObj = CreateObject("PowerPoint.application")

With PPObj      
    .Presentations.Add

    .Presentations.Open Filename:="Y:\Desktop\Month End\One_Shot\Template AVP Report Package\ABD-OME SDeeson.pptx"

    .Visible = True    
    .UpdateLinks    
    .Presentation.Save

    .Quit    
    Set PPObj = Nothing    
End With

End Sub

Answer 1

438表示您正在尝试访问不存在的方法或对象的属性。因此，您需要一个表示对象而不是应用程序对象来更新链接。

试试这样：

Option Explicit

Sub kunal()

    Dim PPObj As Object
    Dim pptPresentation As Object

    Set PPObj = CreateObject("PowerPoint.application")
    Set pptPresentation = PPObj.presentations.Open("C:\test.pptx")

    With PPObj

        .presentations.Add

        .Visible = True
        pptPresentation.UpdateLinks
        pptPresentation.Save
        pptPresentation.Close

        .Quit
        'Set PPObj = Nothing - No need for this
    End With

End Sub

Application Object MSDN

Presentation Object MSDN

Answer 2

首先，如果在以下行打开现有演示文稿，则不确定为什么需要.Presentations.Add。

第二次，.UpdateLinks行是Presentation的属性，而不是PowerPoint.Application。

<强>代码

Option Explicit

Sub kunal()

Dim ppApp As Object
Dim ppPres As Object

Set ppApp = CreateObject("PowerPoint.application")

With ppApp
    .Visible = True

'    .Presentations.Add ' <-- not sure why you need to open a new Presentation ?
    Set ppPres = .Presentations.Open(Filename:="Y:\Desktop\Month End\One_Shot\Template AVP Report Package\ABD-OME SDeeson.pptx")

    ppPres.UpdateLinks
    ppPres.Save
    ppPres.Close

    .Quit
End With

Set ppPres = Nothing
Set ppApp = Nothing

End Sub
