PPT VBA 例程在步进模式下有效，但在运行下无效

Question

我尝试使用幻灯片上的选定图片，然后 copy/paste 将其放入占位符 （我无法从文件加载图片, 它必须来自幻灯片本身。)

当我使用 F8 一步步检查代码时，它工作正常。但是当我运行宏时，占位符保持为空。

我尝试设置Delays来给PPT足够的时间，但是无论我延迟多高，它都不起作用（Placeholder没有被填满）

有什么想法，是什么导致了这种奇怪的行为？更好的想法如何将所选图像放入模板占位符（不过也应该适用于 Mac）。感谢您的宝贵时间！

Sub SetImageIntoPlaceholder()
    Dim sImage As Shape
    Dim iSl As Integer
    Dim oSl As Slide
    Dim oPl As Shape
    On Error GoTo ErrorHandler

    If ActiveWindow.Selection.ShapeRange().Count <> 1 Then
        MsgBox "Please select only the picture you wish to place in the Placeholder", vbOKOnly Or vbCritical, Application.Name
        Exit Sub
    End If
    
    iSl = ActiveWindow.View.Slide.SlideIndex
    Set oSl = ActivePresentation.Slides(iSl)
    Set sImage = ActiveWindow.Selection.ShapeRange(1)
    sImage.Copy
    
    For Each oPl In oSl.Shapes
        If oPl.Type = msoPlaceholder Then
            With oPl
                Select Case oPl.PlaceholderFormat.Type
                    Case Is = 18
                        'Its a picture placeholder
                        Delay 4
                        oPl.Select
                        Delay 4
                        ActiveWindow.View.Paste
                        Delay 5
                        'oSl.Shapes.Paste
                        Application.CommandBars.ExecuteMso ("SlideReset")
                        'Delay 1.5
                        'sImage.Delete
                        Exit Sub
            
                    Case Else
                        ' ignore other shape types
                End Select
            End With
        End If
    Next oPl
    
ErrorHandler:
    'Resume Next
End Sub

尝试在复制和粘贴后添加 DoEvents。此外，尝试将复制和粘贴操作分离到单独的过程中。 VBA 应等到操作完成后再进入和退出程序。我还没有测试过，但也许是这样的。 . .

Option Explicit

Sub SetImageIntoPlaceholder()
    Dim sImage As Shape
    Dim iSl As Integer
    Dim oSl As Slide
    On Error GoTo ErrorHandler

    If ActiveWindow.Selection.ShapeRange().Count <> 1 Then
        MsgBox "Please select only the picture you wish to place in the Placeholder", vbOKOnly Or vbCritical, Application.Name
        Exit Sub
    End If
    
    iSl = ActiveWindow.View.Slide.SlideIndex
    Set oSl = ActivePresentation.Slides(iSl)
    Set sImage = ActiveWindow.Selection.ShapeRange(1)
    sImage.Copy
    
    DoEvents
    
    PastePictureInSlide oSl
    
ErrorHandler:
    'Resume Next
End Sub

Private Sub PastePictureInSlide(ByVal oSl As Slide)

    Dim oPl As Shape
    
    For Each oPl In oSl.Shapes
        If oPl.Type = msoPlaceholder Then
            With oPl
                Select Case .PlaceholderFormat.Type
                    Case Is = 18
                        'Its a picture placeholder
                        .Select
                        ActiveWindow.View.Paste
                        'oSl.Shapes.Paste
                        Application.CommandBars.ExecuteMso ("SlideReset")
                        DoEvents
                        Exit Sub
                    Case Else
                        ' ignore other shape types
                End Select
            End With
        End If
    Next oPl

End Sub
