Question

我正在开发一个自定义工具，可以为给定的演示文稿生成自定义的讲师笔记。我有一个问题，我正在处理一个幻灯片基本上没有Title对象的演示文稿然后我运行代码它是双向传递我的if语句。

我已将代码简化为基础，以使其尽可能简单。

我的测试课有一个正常的幻灯片，文本占位符已填写，下一张幻灯片是没有标题文本框的徽标幻灯片，只有版权信息和徽标，（这是有问题的幻灯片）然后标题占位符所在的另一张幻灯片，但留空。

如何检查单张幻灯片以确保标题占位符存在？

Public Sub GetTitle()
    Dim pres As Presentation    'PowerPoint presentation
    Dim sld As Slide            'Individual slide
    Dim shp As Shape            'EIAG Text Shape
    Dim ShpType As String       'Shape Type
    Dim SldTitle As String      'Slide TITLE

    'Go through each slide object
    Set pres = ActivePresentation
    For Each sld In ActivePresentation.Slides.Range
    On Error Resume Next
        If sld.Shapes(1).PlaceholderFormat.Type = ppPlaceholderCenterTitle Or sld.Shapes(1).PlaceholderFormat.Type = ppPlaceholderTitle Then
            If sld.Shapes.Title.TextFrame.TextRange <> "" Then
                SldTitle = sld.Shapes.Title.TextFrame.TextRange
                Debug.Print SldTitle & " - Slide: " & CStr(sld.SlideNumber)
            Else
                Debug.Print "BLANK TITLE - Slide: " & CStr(sld.SlideNumber)
            End If
        Else
            ShpType = sld.Shapes.Item(1).Type
            Debug.Print ShpType & "Not Processed There is no Title object"
        End If
    Next sld
End Sub

您可以使用Shapes Collection的HastTitle方法检查幻灯片是否具有标题占位符：

If sld.Shapes.HasTitle then

你也不应该依赖标题占位符为形状1，而是循环遍历幻灯片上的所有形状，按如下方式检查每个形状：

Option Explicit

' Function to return an array of title texts from a presentation
' Written by Jamie Garroch at http://youpresent.co.uk
' Inputs : None

Function GetTitlesArr() As Variant
  Dim oSld As Slide
  Dim oShp As Shape
  Dim iCounter As Integer
  Dim arrTitles() As String
  For Each oSld In ActivePresentation.Slides
    For Each oShp In oSld.Shapes
      With oShp
        If .Type = msoPlaceholder Then
          Select Case .PlaceholderFormat.Type
            Case ppPlaceholderCenterTitle, ppPlaceholderTitle
              ReDim Preserve arrTitles(iCounter)
              arrTitles(iCounter) = oShp.TextFrame.TextRange.Text
              iCounter = iCounter + 1
          End Select
        End If
      End With
    Next
  Next
  GetTitlesArr = arrTitles
End Function
