How can I automatically populate the VBA Editor with line numbers?

Question

I want to have line numbers in my VBA code for debugging reasons. That will allow me to know where a particular error occurred.

Is there an automatic feature for thi

I use this code for adding line numbers to my Excel projects. I found it online a while back and I don't remember where I got it, so credit goes to whoever originally wrote this:

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

You'll have to modify it to suit your needs since you're working in Access, but I'm sure the main meat of it still applies. In Excel, there's a userform that is used to kick off the code for the module you specify, but you should be able to just pass in the module name (vbCompName) to specify the module. I'm not well-versed in Access VBA, so I'm not sure what you'd replace Workbooks(wbName) with in the code.
