我试图循环遍历 Excel 文件，打开它们，运行一些破解密码的代码，然后关闭工作簿并移至下一个工作簿。
我的代码适用于我的大多数文件。我在处理包含宏的文件时遇到问题。 （这是我能看到的唯一将这些文件与其他文件区分开来的东西。）
我注意到，当我打开问题文件时，我的 wb 变量被设置为空。它仍然打开文件，并且我的代码继续运行，但是当我执行 wb.close 行时，我的代码只是停止。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，但如果有人可以解释如何执行此操作，我可以。
当我打开一个不会导致此问题的文件时，在本地窗口中展开变量 wb 时，它具有其他属性。在问题文件上，当我展开 wb 变量时，它只是说：没有变量
当我在不使用 VBA 的情况下打开这些文件之一时，我收到一条警告，指出它可能存在安全问题并且宏已被禁用。我认为这就是我的问题所在，但我认为我用以下方式处理这个问题Application.AutomationSecurity = msoAutomationSecurityForceDisable.
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, _
