Word VBA 行长约束

Question

目标： 在 Word 中使用 VBA，我希望能够将文本键入或粘贴到 Word 文档中，然后确保每行单词以一定数量的字符换行（通常为 50，尽管这可能会改变）。我宁愿不使用文档顶部的标尺手动调整，尤其是当字体不是等宽时！

尝试失败： 我尝试使用以下内容，导致错误“值超出范围”：

Public Sub setWordsPerLine()
  ActiveDocument.PageSetup.CharsLine = 50
End Sub

我还尝试在段落中每 50 个字符插入一个返回字符。但是，这会导致类型不匹配错误：

For Each pg In ActiveDocument.Paragraphs
b = pg.Range.Characters.Count
c = 50
If b > c Then
  For atch = c To pg.Range.Characters.Count Step c
    ActiveDocument.Range(pg.Range.Characters(atch)).InsertBefore (Chr(13))
  Next
End If
Next

需要帮助： 我应该使用其他方法、属性或函数来执行此操作吗？ Paragraphs.RightIndent = x 是基于点，而不是字符。

我已经改进了您的第二个解决方案，现在工作正常。 （我用简单的lorem ipsum 文档做了一些测试）。

Sub qTest_line()
    Dim PG As Paragraph
    Dim B, C, ATCH, S

        For Each PG In ActiveDocument.Paragraphs
            B = PG.Range.Characters.Count
            S = PG.Range.Start
        C = 50
        If B > C Then
          For ATCH = (S + C) To (S + B) Step C
            'check the position
            If Len(Trim(ActiveDocument.Range(ATCH - 1, ATCH + 1).Text)) < 2 Then
                'just insert new line mark
                ActiveDocument.Range(ATCH, ATCH).InsertAfter Chr(11)
            Else
                'move to the beginnng of word
                ActiveDocument.Range(ATCH, ATCH).Select
                Selection.MoveLeft wdWord
                Selection.InsertBefore Chr(11)
                ATCH = Selection.Start
            End If

          Next
        End If
        Next
End Sub

Answer 2

KazJaw 的 other answer here 运行良好，但我进行了修改以包含一些改进，并希望发布修改以防其他人遇到此问题。

改进包括：

1. 更好地记录每个步骤。
2. 使用更好的ASCII control character 以便更好地识别段落。

3. 使用更优雅的方法来判断单词是否在中间，通过替换

   If Len(Trim(ActiveDocument.Range(char_index - 1, char_index + 1).Text)) < 2 Then
   

   与

   If ActiveDocument.Range(char_index).Text = " " Or _
   ActiveDocument.Range(char_index).Text = "-" Then
   

4. 现在可以跨行正确拆分带连字符的单词。例如，“servo-valve”现在可以在一行中使用“servo-”，在下一行的开头使用“valve”。

这是修改后的代码，再次感谢 KazJaw 的原始解决方案。
