VBA:如何使VBE中当前光标跳转到最后发生错误的行？

Question

这还是和我之前的问题相关的，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中的当前光标跳转到VBE中的特定过程。我使用 Application.Goto 来实现这一点。然而，我真正想要的是让VBE中的当前光标跳转到最后发生错误的行。我怀疑 Application.VBE 对象中应该有一些对此目的有用的东西，但不知道是哪个？

解决这个问题也意味着完全满足我之前的问题。有什么提示甚至肮脏的伎俩吗？

继续您之前的问题:)

我想您已经在使用行编号(如上一个问题中所回答)。

因此，将错误处理例程修改为:

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

现在来说说 CodeFind() 的事情。我找到了here (在底部，最后一个)，但不得不稍微修改一下，所以我发布了很多代码......抱歉。

将此代码插入新模块中，并确保选中了对“Microsoft Visual Basic For Applications Extensibility 5.3”的引用，并且该项目不 protected 。有疑问请参阅here .

哈!

这是代码
