VBA：如何使VBE中的当前光标跳到最后一个错误发生的行？ [英] VBA: How to make the current cursor in VBE jump to the line where the last error occured?

问题描述

这仍然与我之前的问题有关， VBA：如何显示错误消息，就像标准错误消息中有一个调试按钮？

This is still related with my previous questions, VBA: How to display an error message just like the standard error message which has a "Debug" button?

现在，我成功地使VBE中的当前游标跳转到VBE中的特定过程。我使用 Application.Goto 来实现这一点。但是，实际上我想要的是使VBE中的当前游标跳到最后一个错误发生的行。我怀疑在 Application.VBE 对象中应该有一些有用的东西，但不知道哪个？

Now, I successfully make the current cursor in VBE jump to a particular procedure in VBE. I used Application.Goto to achieve this. However, what actually I want is to make the current cursor in VBE jump to the line where the last error occured. I suspected there should be something useful for this purpose in Application.VBE object but didn't know which?

解决这个也意味着完全满足了我以前的问题。任何提示，甚至是肮脏的技巧？

Solving this also means satisfying my previous question entirely. Any hints or even dirty tricks?

推荐答案

从您以前的问题继续：）

Continued from your previous question :)

我想你已经在使用行编号（如上一个问题回答）。

I suppose you are already using line numbering (as answered in the previous question).

所以，修改你的错误处理程序，如：

So, modify your error handling routine to something like:

Sub aa()
Dim zz As Long

10:     On Error GoTo ErrorHandler
20:     DivisionByZero = 1 / 0
30:     Exit Sub
ErrorHandler:
41:  If Err.Number <> 0 Then
42:     Msg = "Error # " & Str(Err.Number) & " was generated by " _
         & Err.Source & Chr(13) & "Error Line: " & Erl & Chr(13) & Err.Description
43:     MsgBox Msg, , "Error", Err.HelpFile, Err.HelpContext
        zz = CodeFind("", "", Str(Erl), 0)
44:     End If
50:     Resume Next
End Sub

现在为CodeFind （）东西我发现它是 here （最后一个） ，但不得不修改一下，所以我发布了很多代码...对不起。

Now for the CodeFind() thing. I found it here (at the bottom, the last one), but had to modify it a bit, so I'm posting a lot of code ... sorry.

将此代码插入到新的模块中，确保你有检查Microsoft Visual Basic for Applications可扩展性5.3的引用，并且项目不受保护。有疑问请参阅此处。

Insert this code in a new module and be sure you have the reference to "Microsoft Visual Basic For Applications Extensibility 5.3" checked, and the project is not protected. In doubt see here.

HTH！

以下是代码
