如何使用行号自动填充 VBA 编辑器？
How can I automatically populate the VBA Editor with line numbers?
出于调试原因，我想在我的 VBA 代码中包含行号。这将使我知道特定错误发生的位置。
是否有自动功能（例如设置中的选项）？还是我需要自己写宏？
如果我需要编写自己的宏来完成此任务，我将如何着手做这样的事情？
我使用此代码向我的 Excel 项目添加行号。我不久前在网上找到它，但我不记得是从哪里得到的，所以感谢最初写这篇文章的人：
Sub AddLineNumbers(wbName As String, vbCompName As String)
'See MakeUF
Dim i As Long, j As Long, lineN As Long
Dim procName As String
Dim startOfProceedure As Long
Dim lengthOfProceedure As Long
Dim newLine As String
With Workbooks(wbName).VBProject.VBComponents(vbCompName).CodeModule
.CodePane.Window.Visible = False
For i = 1 To .CountOfLines
procName = .ProcOfLine(i, vbext_pk_Proc)
If procName <> vbNullString Then
startOfProceedure = .ProcStartLine(procName, vbext_pk_Proc)
lengthOfProceedure = .ProcCountLines(procName, vbext_pk_Proc)
If startOfProceedure + 1 < i And i < startOfProceedure + lengthOfProceedure - 1 Then
newLine = RemoveOneLineNumber(.Lines(i, 1))
If Not HasLabel(newLine) And Not (.Lines(i - 1, 1) Like "* _") Then
.ReplaceLine i, CStr(i) & ":" & newLine
End If
End If
End If
Next i
.CodePane.Window.Visible = True
End With
End Sub
Sub RemoveLineNumbers(wbName As String, vbCompName As String)
'See MakeUF
Dim i As Long
With Workbooks(wbName).VBProject.VBComponents(vbCompName).CodeModule
For i = 1 To .CountOfLines
.ReplaceLine i, RemoveOneLineNumber(.Lines(i, 1))
Next i
End With
End Sub
Function RemoveOneLineNumber(aString)
RemoveOneLineNumber = aString
If aString Like "#:*" Or aString Like "##:*" Or aString Like "###:*" Then
RemoveOneLineNumber = Mid(aString, 1 + InStr(1, aString, ":", vbTextCompare))
End If
End Function
Function HasLabel(ByVal aString As String) As Boolean
HasLabel = InStr(1, aString & ":", ":") < InStr(1, aString & " ", " ")
End Function
由于您在 Access 中工作，因此您必须修改它以满足您的需要，但我相信它的主要内容仍然适用。在 Excel 中，有一个用户窗体用于为您指定的模块启动代码，但您应该能够只传入模块名称 (vbCompName) 来指定模块。我不太精通 Access VBA，所以我不确定您要用什么替换代码中的 Workbooks(wbName)。
MZ-Tools for VBA 具有向单个函数、模块或整个项目添加和删除行号的功能。
见http://www.mztools.com/v8/onlinehelp/index.html?add_remove_line_numbers.htm
注意 1：我发现将行号增量配置为 1 而不是 10 更好。您永远不会在两者之间手动添加行号 - 每当您编辑代码时，首先删除行号，然后再将它们添加回去当你完成时。
注2：直到几年前，还有免费的MZ-Tools 3.0版本，但出乎意料的难找。但这是一项很好的投资 - 还有许多其他有用的功能（例如，自动添加错误处理程序）。
这对我有用...将其添加到它自己的模块中。调用代码将打开或关闭行号。在引号中添加模块标题 and/or 过程标题将仅更新指定的模块或过程。

VBA 编辑器有一个内置的查看行号的方法，在 'Standard' 工具栏下：
当您 select 一行代码时，行号将显示在 'Ln' 旁边。
这未经过 100% 测试，但使用 VBA 可扩展性，您可以执行以下操作
Sub line_number(strModuleName As String)
Dim vbProj As VBProject
Dim vbComp As VBComponent
Dim cmCode As CodeModule
Dim intLine As Integer
Set vbProj = Application.VBE.ActiveVBProject
Set vbComp = vbProj.VBComponents(strModuleName)
Set cmCode = vbComp.CodeModule
For intLine = 2 To cmCode.CountOfLines - 1
cmCode.InsertLines intLine, intLine - 1 & cmCode.Lines(intLine, 1)
cmCode.DeleteLines intLine + 1, 1
Next intLine
End Sub
前后效果如下，不推荐这样修改。
您不需要行号。
不是为了“调试原因”，不是为了任何事情。行号被弃用是有原因的：它们是远古时代的遗物，甚至还没有过程，而且 GOTO 是到达任何地方的唯一途径。
Erl 仅 returns 在引发错误之前最后遇到的行号 。如果您正在记录错误，这可能意味着误导性错误日志：
Sub DoSomething()
10 On Error GoTo 50
Debug.Print 42 / 0
30 Exit Sub
50 Debug.Print "Error raised on line " & Erl 'returns 10
End Sub
此外，行号只有 Integer 分辨率（一个 VBA 模块最多可以有 65,535 行，是该分辨率的两倍），并且会默默地失败并愉快地报告错误的行号如果你没有记住这一点：
Sub DoSomething()
99997 On Error GoTo 99999
99998 Debug.Print 42 / 0
99999
Debug.Print Erl 'Prints 34462 - and which line is that?
End Sub
任何严重的 VBA 应用程序都将使用 结构化错误处理。
编写小型专用程序（即编写遵循现代最佳实践的代码），行号变得完全没有意义。
维护行号是件头疼的事；它们使代码变得混乱并使其整体更难阅读（因此更难调试）。
也就是说，IIRC MZ-Tools 3 具有这样的功能。
请记住，当行号是一回事时，BASIC 看起来像这样：

Arich 的回答对单个模块很有用。如果您想为整个工作簿提供（更新的）行号，请执行以下步骤*^:
做一次：
- 将
Module2 中的大代码粘贴到您的工作簿中。
- 将
Module3 的代码粘贴到您的工作簿中。
- 将
Module4 的代码粘贴到您的工作簿中。
- 然后粘贴行
Global allow_for_line_addition As String这只是为了让您可以自动添加行号` above/in 每个行的第一行
模块。
- 删除每个模块末尾的所有空行（因此在模块的最后一个
end sub、end function 或 End Property 之后不会输入 lose）。
- 在 VBA 编辑器中，虽然不是 运行 代码，也不处于 "break"-模式：单击工具>参考>标记：`Microsoft Visual Basic for Applications Extensibility 5.3
每次修改代码时做：
- °运行
Module3 的代码删除工作簿中所有模块的行号。
- °运行
Module4 的代码，用于向工作簿中的所有模块添加行号。

您可以将 "Book1.xlsm" 替换为您自己的工作簿的名称，或替换为 thisworkbook（注意没有“”），反之亦然。
- *注意这在 excel 2016 年有效，我在 2013 年还没有尝试过。
- ^它是 Hemced 的答案 here. 的修改版本，反过来看起来很像 Arich 的答案。
- °因为有时如果您剪掉或移动它们（例如将
line 2440: 放在 line 2303: 上方），您会得到一个错误。通过删除并重新添加它们，行号将再次自动正确。
任何体面的错误处理程序都会报告不仅仅是行号。它将报告错误模式、描述和发生错误的模块。无论 ERL 是否在整个应用程序中重复行号，如果您无法通过报告的其他线索找到问题，也许您需要休假。或者，地狱，添加一个变量，该变量将模块级 alpha 代码递增作为行号的附件，如“newERL = strProcLevel & ERL”，为您提供“A12345”作为行号。
出于调试原因，我想在我的 VBA 代码中包含行号。这将使我知道特定错误发生的位置。
是否有自动功能（例如设置中的选项）？还是我需要自己写宏？
如果我需要编写自己的宏来完成此任务，我将如何着手做这样的事情？
我使用此代码向我的 Excel 项目添加行号。我不久前在网上找到它，但我不记得是从哪里得到的，所以感谢最初写这篇文章的人：

由于您在 Access 中工作，因此您必须修改它以满足您的需要，但我相信它的主要内容仍然适用。在 Excel 中，有一个用户窗体用于为您指定的模块启动代码，但您应该能够只传入模块名称 (vbCompName) 来指定模块。我不太精通 Access VBA，所以我不确定您要用什么替换代码中的 Workbooks(wbName)。
MZ-Tools for VBA 具有向单个函数、模块或整个项目添加和删除行号的功能。
见http://www.mztools.com/v8/onlinehelp/index.html?add_remove_line_numbers.htm
注意 1：我发现将行号增量配置为 1 而不是 10 更好。您永远不会在两者之间手动添加行号 - 每当您编辑代码时，首先删除行号，然后再将它们添加回去当你完成时。
注2：直到几年前，还有免费的MZ-Tools 3.0版本，但出乎意料的难找。但这是一项很好的投资 - 还有许多其他有用的功能（例如，自动添加错误处理程序）。
这对我有用...将其添加到它自己的模块中。调用代码将打开或关闭行号。在引号中添加模块标题 and/or 过程标题将仅更新指定的模块或过程。

VBA 编辑器有一个内置的查看行号的方法，在 'Standard' 工具栏下：
当您 select 一行代码时，行号将显示在 'Ln' 旁边。
这未经过 100% 测试，但使用 VBA 可扩展性，您可以执行以下操作
Sub line_number(strModuleName As String)
Dim vbProj As VBProject
Dim vbComp As VBComponent
Dim cmCode As CodeModule
Dim intLine As Integer
Set vbProj = Application.VBE.ActiveVBProject
Set vbComp = vbProj.VBComponents(strModuleName)
Set cmCode = vbComp.CodeModule
For intLine = 2 To cmCode.CountOfLines - 1
cmCode.InsertLines intLine, intLine - 1 & cmCode.Lines(intLine, 1)
cmCode.DeleteLines intLine + 1, 1
Next intLine
End Sub
前后效果如下，不推荐这样修改。
您不需要行号。
不是为了“调试原因”，不是为了任何事情。行号被弃用是有原因的：它们是远古时代的遗物，甚至还没有过程，而且 GOTO 是到达任何地方的唯一途径。
Erl 仅 returns 在引发错误之前最后遇到的行号 。如果您正在记录错误，这可能意味着误导性错误日志：
Sub DoSomething()
10 On Error GoTo 50
Debug.Print 42 / 0
30 Exit Sub
50 Debug.Print "Error raised on line " & Erl 'returns 10
End Sub
此外，行号只有 Integer 分辨率（一个 VBA 模块最多可以有 65,535 行，是该分辨率的两倍），并且会默默地失败并愉快地报告错误的行号如果你没有记住这一点：
Sub DoSomething()
99997 On Error GoTo 99999
99998 Debug.Print 42 / 0
99999
Debug.Print Erl 'Prints 34462 - and which line is that?
End Sub
任何严重的 VBA 应用程序都将使用 结构化错误处理。
编写小型专用程序（即编写遵循现代最佳实践的代码），行号变得完全没有意义。
维护行号是件头疼的事；它们使代码变得混乱并使其整体更难阅读（因此更难调试）。
也就是说，IIRC MZ-Tools 3 具有这样的功能。
请记住，当行号是一回事时，BASIC 看起来像这样：

Arich 的回答对单个模块很有用。如果您想为整个工作簿提供（更新的）行号，请执行以下步骤*^:
做一次：
- 将
Module2中的大代码粘贴到您的工作簿中。 - 将
Module3的代码粘贴到您的工作簿中。 - 将
Module4的代码粘贴到您的工作簿中。 - 然后粘贴行
Global allow_for_line_addition As String这只是为了让您可以自动添加行号` above/in 每个行的第一行 模块。 - 删除每个模块末尾的所有空行（因此在模块的最后一个
end sub、end function或End Property之后不会输入 lose）。 - 在 VBA 编辑器中，虽然不是 运行 代码，也不处于 "break"-模式：单击工具>参考>标记：`Microsoft Visual Basic for Applications Extensibility 5.3
每次修改代码时做：
- °运行
Module3的代码删除工作簿中所有模块的行号。 - °运行
Module4的代码，用于向工作簿中的所有模块添加行号。

您可以将 "Book1.xlsm" 替换为您自己的工作簿的名称，或替换为 thisworkbook（注意没有“”），反之亦然。
- *注意这在 excel 2016 年有效，我在 2013 年还没有尝试过。
- ^它是 Hemced 的答案 here. 的修改版本，反过来看起来很像 Arich 的答案。
- °因为有时如果您剪掉或移动它们（例如将
line 2440:放在line 2303:上方），您会得到一个错误。通过删除并重新添加它们，行号将再次自动正确。
