【问题描述】：

我在这里遇到了一些麻烦。我的代码停止运行时错误 -2147467259 (80004005) Mehod 'Open' of object 'Presentations: failed.

此代码显示警告，提示输入源文件夹和目标文件夹，并循环访问源文件夹中的所有文件，打开每个文件并将每张幻灯片导出为单独的文件，并再次导出到文件夹中的最后一个文件。

我放了几个 msgbox 看看是不是名字有问题，根据 MVP Andy Pope 的一些代码重新编写了打开的文件段，但什么都没有。

非常感谢任何帮助。

【问题讨论】：

您打开每个文件两次，一次是在新实例中（使用SourceNamePath），另一次是在当前实例中（使用SourcePresentationName）？你的意思是这样做吗？为什么要在这里新建一个 PPT 实例？
蒂姆，我不是故意的。我试图变化。无意留下第二个没有评论。两者都给了我同样的错误。提前致谢。

这对我有用：

Sub ExportIndividualSlides()
    'use const for fixed values
    Const SOURCE_FOLDER As String = "c:\source\" 'include terminal \
    Const TARGET_FOLDER As String = "c:\target\"
    
    Dim objPres As PowerPoint.Presentation
    Dim Slide As Long
    Dim SourcePresentationName As String
    Dim TargetFileName As String
    Dim TargetNamePath As String
    Dim SourceNamePath
    
    Debug.Print "-- Start --------------------------------"
    ActiveWindow.ViewType = ppViewNormal
    
    On Error GoTo errorhandler
    
    'Loop through ppt* files only in source folder
    SourcePresentationName = Dir(SOURCE_FOLDER & "*.ppt*")
    Do While Len(SourcePresentationName) > 0
        
        SourceNamePath = SOURCE_FOLDER & SourcePresentationName
        Debug.Print "Opening: " & SourceNamePath
        
        Set objPres = Presentations.Open(SourceNamePath)
        
        ' Loop through slides
        For Slide = 1 To objPres.Slides.Count
            
            Debug.Print "   Slide: " & Slide
            ' Create a unique filename and save a copy of each slide
            TargetFileName = Left(objPres.Name, InStrRev(objPres.Name, ".") - 1) & " [" & Slide & "].pptx"
            TargetNamePath = TARGET_FOLDER & TargetFileName
            Debug.Print "   TargetNamePath: " & TargetNamePath
            objPres.Slides(Slide).Export TargetNamePath, "PPTX"
        
        Next Slide
        
        objPres.Close
        
        SourcePresentationName = Dir() 'next file
    Loop
    
    Exit Sub
     
errorhandler:
    Debug.Print Err, Err.Description
    Resume Next
    
End Sub
