Powerpoint VBA 函数 return 不工作
Powerpoint VBA function return not working
这快把我逼疯了：我在 powerpoint 中有一个 sub 和一个函数 vba。
子程序首先允许我 select 一个目录。从子调用的函数在目录中查找文件。我希望它作为 sub 之外的函数，因为我需要多次使用它。
潜艇仍在开发中，所以做的不多，但可以用。如果我给它一些事情，这个函数也可以工作——比如打开找到的文件（即取消注释下面我的代码中的那一行）——但我一辈子都不能把它拿到 return 的文件路径子。请帮忙！

我是一个完全 VBA 的菜鸟，所以只是 pva 将我在网上找到的东西粘在一起。它不工作是因为 findFile 循环 returning 一个数组而不是一个字符串吗？我认为 'Exit Function' 电话会解决这个问题。
请原谅递归 if 语句 - 我这样做的人没有完全标准的方式来存储他们的 ppt，但这磨练了我想要的 ppt。当 sub 完成时，它自己将循环遍历 selected 目录的 130 个子目录，并且在每个子目录中，它将从六个不同的 ppt 中抓取各种幻灯片并将它们合并为一个，即合并来自780 ppts 变成 130 - 我绝对想自动化！
这是我在 stack Overflow 上发布的第一个问题，所以我希望我已经清楚正确地提出了它。我已经广泛搜索了解决方案。我希望解决方案突然出现给你！非常感谢。
这是一个需要使用Option Explicit的经典案例。
您缺少 filename 中的 f，这作为变量 ilename 而不是 filename 未选中。
您应该将 Option Explicit 放在每个模块的顶部并声明所有变量。我添加的 GoTo 语句也缺少标签。
注意：您正在对所选文件夹中的文件名执行区分大小写的完整字符串匹配。

行得通。 下面是对我来说更好的解决方案。它使用单独的子/功能来执行以下操作：选择一个文件夹；遍历第一个子文件夹；使用部分文件名在所有文件夹和子文件夹中递归搜索文件；对找到的 file/s 做一些事情（如果在多个字符串上调用搜索函数，则为复数）。
没有必要像这样分开，但我发现这样更容易分离关注点并保持简单。
