使用多个工作簿（从列表中的工作簿复制到主工作表）时，是否有在VBA中使用ActiveWorkbook和ActiveSheet的替代方法？在处理需要使用不同工作簿的多个功能时，要知道哪个工作簿是开放的，这比任何事情都更令人困惑。这是代码组织的问题吗？
目前我认为我可以通过在每个函数的开头存储activeworkbook的名称并进行恢复来管理，但这似乎需要很多工作，并且可能需要很多处理时间才能得到很多结果。
想法？
答案 0 :(得分：3)
具体看4：明确引用工作簿
或10：请参阅工作表的代码名称属性
答案 1 :(得分：1)
通常，当您处理列表时，您将使用工作簿变量来打开，操作然后关闭每本书
下面的代码是一个完成工作簿目录并整理工作簿目录的示例（类似于您的列表示例）。来自Collating worksheets from one or more workbooks into a summary file
