我几天前刚开始使用VBA。我注意到一些命令在我的计算机上似乎不起作用,我想知道这是否是由于我的计算机设置。
我在Windows 7上的PowerPoint 2013中使用VBA,通过MacOSX上的VMware Fusion(虚拟机)运行。我需要为活动幻灯片创建一个动态引用,但是这样做的几种方法破坏了我的代码:
Set oSl = Application.ActiveWindow.View.Slide
(如建议here)
Set oSl = ActivePresentation.Slides(ActiveWindow.View.Slide.SlideNumber)
(如建议here)
Set oSl = ActiveWindow.Selection.SlideRange.SlideIndex
(如建议here)
这些都不适合我。由于我刚开始使用VBA,我只是在代码的不同部分之后插入消息框,并查看何时不再触发的框 - 在这种情况下始终在“oSl =”行之后,我用上面描述的各种其他方法替换。另外,
Set oSl = ActiveWindow.Selection.SlideRange(1)
也破坏了我的代码(如here所述)
到目前为止,DID的工作是什么
Set oSl = ActivePresentation.SlideS(1)
上述所有不起作用的方法(但应该)都包含“ActiveWindow”。如果您可以建议我选择活动幻灯片的方法是否有错误,或者问题是VBA无法正确访问“ActiveWindow”,因为我的PowerPoint在虚拟机上运行,那将会很棒。如果是这种情况,是否有另一种方法可以在不使用ActiveWindow的情况下选择当前活动的幻灯片?
编辑:我正在尝试将此应用于PowerPoint中的以下代码。基本上我想做的是用一行代码替换行“oSl = ActivePresentation.SlideS(1)”,该代码行并不总是以幻灯片1为目标,而是当前活动的幻灯片。我的问题不是如何做到这一点 - 有关于如何在线进行的大量说明。我的问题是为什么这些方法对我不起作用。
