p;   void CPowerPntDlg::OnBtnLast()
         {
                  Presentation = app.GetActivePresentation();
                  SlideShowWindow = Presentation.GetSlideShowWindow();
                  View = SlideShowWindow.GetView();
                  View.Last();
         }
（12）   既然你有了运行的幻灯片放映，你显然会在一些时间点上回到上一张幻灯片。要这样做，使用下列代码：
         void CPowerPntDlg::OnBtnPrevious()
         {
                  Presentation = app.GetActivePresentation();
                  SlideShowWindow = Presentation.GetSlideShowWindow();
                  View = SlideShowWindow.GetView();
                  View.Previous();
         }

（13）   现在有兴趣到下一张幻灯片？在这种情况下，这个函数会帮助你：
       void CPowerPntDlg::OnBtnNext()
         {
                  Presentation = app.GetActivePresentation();
                  SlideShowWindow = Presentation.GetSlideShowWindow();
                  View = SlideShowWindow.GetView();
                  View.Next();
         }
这就是了，伙计。检查出其他转变，动画制作等的可用函数。你可以用你特有的方式进行。
这是基本框架，你可以看出它处理POWERPOINT是多么容易。用在WORD，EXCEL和其它MS-OFFICE上也是一会事。祝好运和快乐！
