[英]Muting and Unmuting multiple audio media on one slide in Powerpoint using VBA
I use PowerPoint 2016 on Windows 10. Slide A has a text box and a command button.我在 Windows 10 上使用 PowerPoint 2016。幻灯片 A 有一个文本框和一个命令按钮。 When the command button is selected, a boolean
gbool
is set and the presentation advances to Slide B.当命令按钮被选中时,一个布尔
gbool
被设置并且演示文稿前进到幻灯片 B。
ActivePresentation.SlideShowWindow.View.GotoSlide <slideB slideindex>
On Slide B, there are two audio media objects, AM1 and AM2.在幻灯片 B 上,有两个音频媒体对象,AM1 和 AM2。 What I want to happen is if
gbool
is True then AM1 should play else AM2 should play.我想要发生的是,如果
gbool
为 True,那么 AM1 应该播放,否则 AM2 应该播放。 I have used the muted flag to attempt this:我已经使用静音标志来尝试这个:
Shape.MediaFormat.Muted = False
The problem I have is that, this sometimes works, other times both audio medias will play.我的问题是,这有时有效,有时两个音频媒体都会播放。 The code looks like this:
代码如下所示:
Private Sub CommandButton1_Click()
Dim osl As Slide, oSh As Shape, gbool As Boolean
gbool = function()
Set osl = ActivePresentation.Slides(<slideB slideindex>)
Set oSh = osl.Shapes("AM1")
oSh.MediaFormat.Muted = gbool
Set oSh = osl.Shapes("AM2")
oSh.MediaFormat.Muted = Not gbool
ActivePresentation.SlideShowWindow.View.GotoSlide <slideB slideindex>
End Sub
Any ideas for the random behaviour and is there a better way to do this?关于随机行为的任何想法,有没有更好的方法来做到这一点?
I think I have an answer - at least this method works all the time.我想我有一个答案——至少这种方法一直有效。 Instead of using the muted property of the MediaFormat object, I now use the PlayOnEntry property of the Play Settings object.
我现在不使用 MediaFormat 对象的静音属性,而是使用播放设置对象的 PlayOnEntry 属性。 So the change looks like this:
所以变化看起来像这样:
Set osl = ActivePresentation.Slides(<slideB slideindex>)
Set oSh = osl.Shapes("AM1")
oSh.AnimationSettings.PlaySettings.PlayOnEntry = gbool
Set oSh = osl.Shapes("AM2")
oSh.AnimationSettings.PlaySettings.PlayOnEntry = Not gbool
If there is a better way, I would appreciate to know it.如果有更好的方法,我将不胜感激。
