将MS Access表单和类/模块递归导出到文本文件？

将MS Access表单和类/模块递归导出到文本文件？

我在古老的留言板上找到了一些代码,可以很好地从类,模块和表单中导出所有VBA代码(见下文):

Dim LineCount As Long                  'Line count of current module

I = InStrRev(CurrentDb.Name, "\")
TopDir = VBA.Left(CurrentDb.Name, I - 1)

但是,这段代码并没有解决我的问题,因为我有110毫秒的访问权限*.mdb,我需要将vba导出到适合grepping的文本文件中.

我感兴趣的110个文件的路径已经存储在一个表中,我的代码已经递归地获得了这些信息(以及其他一些过滤)......所以递归部分就完成了.

大多数这些文件是由一个访问用户安全文件打开的.mdw,我尝试了几种打开它们的方法.当我在这些目录中搜索链接表时,ADO和ADOX工作得很好......但上面的代码涉及到从中导出数据的数据库内部,我希望能够从打开所有数据的单独数据库中执行此操作的mdbs并执行每个导出.

我在此尝试之一涉及使用PrivDBEngine类从外部连接到数据库,但它不允许我访问Application对象,这是上面的导出代码所需要的.

Private Sub exportToFile(db_path As String, db_id As String, loginInfo As AuthInfoz, errFile As Variant)

    Set ws = pdbeNew.Workspaces(0)


    Set db = ws.OpenDatabase(db_path)

您也可以尝试此代码.它将保留项目文件类型(.BAS,.CLS,.FRM)还记得提及/检查的Microsoft Visual Basic for Applications扩展库在 VBE>工具>参考

                Sfx = ".cls"
            Case vbext_ct_MSForm
                Sfx = ".frm"
            Case vbext_ct_StdModule

            Case Else

您可以使用Access.Application对象.

此外,为了避免在打开数据库时出现多个确认对话框,只需更改工具/宏/安全性中的安全级别.

要使用用户/密码打开多个数据库,您可以加入工作组(工具/安全/工作组管理员)并使用所需的用户/密码(使用SaveToFile函数从数据库)登录,然后运行代码.请记住,稍后加入默认工作组(您可以尝试加入不存在的工作组,访问权限将恢复为默认值).

Const VB_MODULE = 1
Const VB_CLASS = 2

Const EXT_MODULE = ".bas"

Const EXT_FORM = ".frm"
Const CODE_FLD = "Code"

Sub ExportAllCode()

Dim fileName As String
Dim exportPath As String
Dim ext As String
Dim FSO As Object

Set FSO = CreateObject("Scripting.FileSystemObject")
' Set export path and ensure its existence
exportPath = CurrentProject.path & "\" & CODE_FLD
If Not FSO.FolderExists(exportPath) Then
    MkDir exportPath
End If

' The loop over all modules/classes/forms
For Each c In Application.VBE.VBProjects(1).VBComponents

    If ext <> "" Then
