最近自己在做一个手机通过wifi控制电脑ppt播放，然后基本的播放暂停还有翻页功能都实现了，现在想知道com里面的那个powerpoint的接口怎么获取最近打开的ppt文件，还有当打开新的ppt文件的事件要怎么监听等等，希望能给个思路
------解决思路----------------------
public static void ShowPPT(string strTemplate)
{
PowerPoint.Application objApp;
PowerPoint.Presentations objPresSet;
PowerPoint._Presentation objPres;
PowerPoint.Slides objSlides;
PowerPoint.SlideShowWindows objSSWs;
PowerPoint.SlideShowSettings objSSS;
PowerPoint.SlideRange objSldRng;
bool bAssistantOn;
try
{
objApp = new Microsoft.Office.Interop.PowerPoint.Application();
objApp.Visible = MsoTriState.msoTrue;
objPresSet = objApp.Presentations;
objPres = objPresSet.Open(strTemplate, MsoTriState.msoFalse, MsoTriState.msoTrue, MsoTriState.msoTrue);
objSlides = objPres.Slides;
//Modify the slide show transition settings for all 3 slides in //the presentation.
int[] SlideIdx = new int[3];
for (int i = 0; i < 3; i++) SlideIdx[i] = i + 1;
objSldRng = objSlides.Range(SlideIdx);
//objSST = objSldRng.SlideShowTransition;
//objSST.AdvanceOnTime = MsoTriState.msoTrue;
//objSST.AdvanceTime = 3;
// objSST.EntryEffect = Microsoft.Office.Interop.PowerPoint.PpEntryEffect.ppEffectBoxOut;
//Prevent Office Assistant from displaying alert messages:
bAssistantOn = objApp.Assistant.On; objApp.Assistant.On = false;
//Run the Slide show from slides 1 thru 3.
objSSS = objPres.SlideShowSettings;
objSSS.StartingSlide = 1;
objSSS.EndingSlide = 3;
objSSS.Run();
//Wait for the slide show to end.
objSSWs = objApp.SlideShowWindows;
while (objSSWs.Count >= 1)
System.Threading.Thread.Sleep(100);
//Reenable Office Assisant, if it was on:
if (bAssistantOn)
{
objApp.Assistant.On = true;
objApp.Assistant.Visible = false;
}
objPres.Close();
objApp.Quit();
}
catch
{
}
finally
{
//Close the presentation without saving changes and quit PowerPoint.
}
}

这是播放PPT代码，using Microsoft.Office.Interop.PowerPoint;

监听的话，可监控PPT进程
