我正在将 powerpoint (ppt) 幻灯片中的图表链接到 Excel (xls) 工作簿中的图表。这在没有 vba 代码的情况下可以正常工作，因为我只是使用特殊粘贴来创建链接。但是，问题是当我更改 ppt 和 xls 的目录时，因为 ppt 仍会尝试从旧目录中的 xls 更新数据。然而，我的目标是分享这些文件，这样每个人都可以用他们的 xls 更新他们的 ppt。

所以，简而言之，我想更新 ppt，但选择不同的工作簿（具有不同的目录）。这本工作簿在结构上与旧工作簿相同，只是数据不同。

我知道有方法 updatelinks，但似乎没有任何方法可以使用此方法选择不同的目录。有没有人有任何提示？

使用 MS-OFFICE 2010 试用和测试

我已经对代码进行了注释，以便您理解它不会有问题。如果您仍然这样做，请随时询问。
