VBA错误1101：值无效
此代码打开一堆MS Project 2016文档，并将内容转储到Excel 2016表单中。 MS Project文件path在范围（rng2）C2：C＆Last Row中。 每次通过时，1101错误都会在达到范围中的第六项时抛出。 在PrjApp.FileOpenEx rng2失败。
- 无论文件path如何在范围内sorting，都会发生错误。
- 当文件path一次被testing1时代码运行完成，所以我知道path和文件是好的。
- 手表显示rng2值正是在故障发生时的情况（例如，将值设置为所需的文件path）。
这对我来说没有意义，但是代码一定有问题。 有任何想法吗？

因此，将您的非限定引用修改为OutlineShowAllTasks ， SelectTaskColumn和EditCopy方法，以便它们显式引用您的PrjApp应用程序对象，例如
PrjApp.OutlineShowAllTasks '... PrjApp.SelectTaskColumn Column:="Name" PrjApp.EditCopy '... etc
即使它没有避免内存和引用问题，明确地指定应用程序也会让别人更容易理解你的代码 – 通过包含PrjApp. 他们可以很容易地看到诸如OutlineShowAllTasks类的东西是MSProject方法，并且他们没有花时间浏览你的Excel代码寻找一个Sub OutlineShowAllTasks() （这是我第一次看到你的代码时所做的）。
