Excel 在工作簿上的文件中循环时停止代码。关闭

我正在尝试循环浏览Excel文件，打开它们，运行一些代码来破解密码，然后关闭工作簿并移动到下一个工作簿

我的代码适用于我的大多数文件。我对包含宏的文件有问题。（这是我能看到的唯一区别于其他文件的东西。）

我注意到，对于问题文件，当我打开它们时，我的wb变量设置为nothing。它仍然打开文件，我的代码继续运行，但当我执行wb.close行时，我的代码就停止了。没有错误消息，但它没有完成它所在的循环

不确定是否有一种方法可以附加一个有效的文件和一个无效的文件，但如果有人能解释如何做，我可以

当我打开一个不会导致此问题的文件时，在我展开变量wb时的“局部变量”窗口中，它具有其他属性。关于问题文件，当我展开wb变量时，它只是说：无变量

当我在不使用VBA的情况下打开其中一个文件时，会收到一条警告，指出该文件可能存在安全问题，并且宏已被禁用。我想这就是我的问题所在，但是我认为我正在使用

Application.AutomationSecurity=msoAutomationSecurityForceDisable

处理这个问题

我已将代码更新为以下内容，但它没有解决在wb.close上停止代码的问题

Do While fileName <> vbNullString

    Set wb = Workbooks.Open(fileName:=directory & fileName, _
                            UpdateLinks:=0, _
                            IgnoreReadOnlyRecommended:=True, _
                            Notify:=False, _
                            CorruptLoad:=xlNormalLoad)
    If Err.Number = 0 And Not wb Is Nothing Then
        On Error GoTo 0
        Call AllInternalPasswords
        wb.Close True
        fileName = Dir()
    Else
        Err.Clear
        On Error GoTo 0
    End If
Loop

Do While fileName vbNullString
设置wb=Workbooks.Open（文件名：=目录和文件名_
UpdateLink:=0_
IgnoreReadOnlyRecommended:=真_
通知：=假_
损坏负载：=xlNormalLoad）
如果Err.Number=0且非wb为空，则
错误转到0
调用所有内部密码
wb.Close为真
fileName=Dir（）
其他的
呃，明白了
错误转到0
如果结束
