C＃ - 以编程方式推进Powerpoint幻灯片放映的方式？

I'd like to be able to advance through a Powerpoint presentation by pressing buttons in a Windows form. Here's some code I've found from http://bytes.com/topic/c-sharp/answers/272940-open-powerpoint-presentation-c-window-form that opens a Powerpoint presentation slide show:

我希望能够通过按Windows窗体中的按钮来推进Powerpoint演示。以下是我从http://bytes.com/topic/c-sharp/answers/272940-open-powerpoint-presentation-c-window-form中找到的一些代码,它打开了一个Powerpoint演示幻灯片:

Microsoft.Office.Interop.PowerPoint.Application oPPT;
Microsoft.Office.Interop.PowerPoint.Presentations objPresSet;
Microsoft.Office.Interop.PowerPoint.Presentation objPres;

//the location of your powerpoint presentation
string strPres = @"filepath";

//Create an instance of PowerPoint.
oPPT = new Microsoft.Office.Interop.PowerPoint.ApplicationClass();

// Show PowerPoint to the user.
oPPT.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;

objPresSet = oPPT.Presentations;

//open the presentation
objPres = objPresSet.Open(strPres, MsoTriState.msoFalse,
MsoTriState.msoTrue, MsoTriState.msoTrue);

objPres.SlideShowSettings.Run();

I haven't found any methods that can advance through the slides, however. Any ideas?

但是,我没有找到任何可以通过幻灯片前进的方法。有任何想法吗?

(Really what I'm trying to do is use the WiiRemote to advance the slides, for a student project).

The method to advance programatically is "SlideShowWindow.View.Next". You can also use "SlideShowWindow.View.Previous" to go backwards.

以编程方式推进的方法是“SlideShowWindow.View.Next”。您也可以使用“SlideShowWindow.View.Previous”向后退。

Looks like there is a method called GotoSlide that will work, just needed to dig a little more! For instance:

看起来有一个名为GotoSlide的方法可以工作,只需要多挖一点!例如:

int i = 0;
while (true)
{
    i++;
    objPres.SlideShowWindow.View.GotoSlide(i, MsoTriState.msoFalse);
    System.Threading.Thread.Sleep(5000);
}

#3

I think you could do this to run them one at a time, for instance:

我认为你可以这样做,一次一个地运行它们,例如:

oSettings = objPres.SlideShowSettings
oSettings.StartingSlide = 3
oSettings.EndingSlide = 3

oSettings.Run()
Do While oApp.SlideShowWindows.Count >= 1
    System.Windows.Forms.Application.DoEvents()
Loop

You might have get a answer for you question, However for the people who will face the same kind of problem I will send a link for a opensource C# code which handles this kind of situation smoothly.

您可能已经得到了一个问题的答案,但是对于将面临同样问题的人,我将发送一个开源C#代码的链接,该代码可以顺利地处理这种情况。

Download the zip file, inside there is a c# project which controls power point slides perfectly

下载zip文件,里面有一个c#项目,可以完美地控制功率点幻灯片

Best wishes folks.
