【问题标题】:Updatelinks in Powerpoint from identical workbook in different directory (through vba?)从不同目录中的相同工作簿更新 Powerpoint 中的链接(通过 vba?)
【发布时间】:2015-12-01 18:28:58
【问题描述】:
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。然而,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)。此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。有人有什么建议吗?
