在双显示器系统中，找出显示PowerPoint幻灯片放映在哪个显示器上 [英] In a dual-monitor system, finding out on which monitor a PowerPoint slideshow is displayed

问题描述

在多监视器系统上运行的Powerpoint 2007/2010中，我们可以选择要在其上显示幻灯片的监视器，方法是转到幻灯片->设置幻灯片->在...上显示幻灯片并选择

In Powerpoint 2007/2010 run on a multiple monitor system, we can select the monitor on which the slideshow will be shown by going to "Slide Show"-> "Set up slideShow" -> "Display SlideShow on" and selecting the desired monitor.

是否可以通过编程方式确定这些设置（例如使用VBA）？

Is it possible to programmatically determine these settings (e.g. using VBA)?

我该怎么办？实际需要的是显示幻灯片的监视器的像素分辨率。
我该怎么做？

What I actually need is the pixel-resolution of the monitor on which the slideshow is shown. How can I do that?

推荐答案

尝试一下：

With SlideShowWindows(1)
Debug.Print .Height
Debug.Print .Width
End With

这将为您带来得分。
到英寸有72点，所以：

That'll give you results in points. There are 72 points to the inch, so:

ResultInPixels =（ResultInPoints * WindowsDPI）/ 72

ResultInPixels = (ResultInPoints * WindowsDPI) / 72

通常WindowsDPI是96，但是您不能依靠它。对GetSystemMetrics的
API调用将为您提供当前值。

Typically WindowsDPI is 96 but you can't rely on that. API calls to GetSystemMetrics will give you the current value.
