操作 TextRange 时 Mac 与 Windows 与 Lines/Paragraphs 的差异

Question

更新

I found out that the vbCrLf is a vbLf on mac -- and https://whosebug.com/users/1188513/mathieu-guindon came to the same conclusion parallel. Now I also found out that in Mac the TextRange is interpreted as LINES instead of PARAGRAPHS.

为了创建议程然后删除前两段，我需要以下代码：

                    With ActivePresentation.SectionProperties
                    MsgBox "We gather now the Section headers"
                        For iSectIndex = 1 To .Count
                        If ActivePresentation.SectionProperties.Name(iSectIndex) <> "" Then
                            #If Mac Then

                            sSectionCollector = sSectionCollector & vbLf & ActivePresentation.SectionProperties.Name(iSectIndex)
                            #Else
                            sSectionCollector = sSectionCollector & vbCrLf & ActivePresentation.SectionProperties.Name(iSectIndex)
                            #End If
                        End If
                        Next iSectIndex
                    End With

                    sAgendaTextblock.TextFrame2.TextRange.Text = sSectionCollector

                    #If Mac Then
                    MsgBox "starting to delete"
                    MsgBox "line 1: " & sAgendaTextblock.TextFrame2.TextRange.Paragraphs(1).Lines(1).Text
                    sAgendaTextblock.TextFrame2.TextRange.Paragraphs(1).Lines(1, 2).Delete

                    #Else
                    MsgBox "starting to delete"
                    MsgBox "paragraph 1: " & sAgendaTextblock.TextFrame2.TextRange.Paragraphs(1).Text
                    sAgendaTextblock.TextFrame2.TextRange.Paragraphs(1, 2).Delete
                    #End If

旧代码/不再相关：

抱歉，这肯定不漂亮 - 我是 VBA 初学者。此代码在 windows 上运行完美，但在 Mac 上抛出 6/Overflow。我知道我可以用 #IF Mac 重新编程 - 但首先我需要了解为什么它会抛出该错误 - 当我尝试将它读入 sSectionCollector 字符串时，它似乎是第 280 行可能 SectionProperties.Name

THE CODE IS RUNNING NOW AS AN ADDIN WITHOUT ERRORS BUT IT PRODUCES DIFFERENT RESULT Windows Under Windows ok Under Mac it somehow doubles the lines Unfortunately I can not see/stepinto/debug the code in a Addin in VBAEditor :-(

Answer 1

问题在这里：& vbCrLf &

这是 Windows 上的换行符（Chr$(10) & Chr$(13)），但是 Mac 使用 Linux 样式的行结尾，如果您的 VBA代码在两个平台上都需要运行，那么最简单的方法就是将vbCrLf替换为vbNewLine.

vbNewLine 将在 Windows 上 vbCrLf，vbCr 在 Mac 上：

docs.microsoft.com

Platform-specific new line character; whichever is appropriate for current platform

这就是 Mac 上出现双线的原因。为 vbNewLine 更改硬编码的 Windows-特定 vbCrLf 将修复行尾，解决问题。
