Powerpoint Viewer控件C＃/ VB/.NET

Question

任何人都知道如何制作一个或如何下载控件来查看PowerPoint文档？

我查过了，但是唯一出现的是this，这绝对不是免费的。我相信微软必须拥有一个能够做到这一点的控制。

做一个控制，做它也欢迎。

这里有我正在寻找的问题的解决方案。 如果任何人有同样的问题，我离开这里后，我做了很多小时的工作后，我的解决方案。

 [DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)] 
     static extern IntPtr FindWindow(IntPtr ZeroOnly, string lpWindowName); 

     [DllImport("user32.dll", SetLastError = true)] 
     static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent); 

     [DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)] 
     public static extern bool SetWindowText(IntPtr hwnd, String lpString); 


     private string FileName = ""; 
     PowerPoint.Application application; 
     PowerPoint.Presentation presentation; 
     bool flag = false; 

     public UserControl1() 
     { 
      InitializeComponent(); 
     } 


     public void open() 
     { 
      sair(); 

      openFileDialog1.Filter = "Powerpoint file (*.ppt)|*.ppt|All files (*.*)|*.*"; 

      if (openFileDialog1.ShowDialog() == DialogResult.OK) 
      { 
       FileName = openFileDialog1.FileName; 

       IntPtr screenClasshWnd = (IntPtr)0; 
       IntPtr x = (IntPtr)0; 

       flag = true; 

       application = new PowerPoint.Application(); 
       presentation = application.Presentations.Open2007(FileName, Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoTrue); 
       PowerPoint.SlideShowSettings sst1 = presentation.SlideShowSettings; 


       sst1.ShowType = (PowerPoint.PpSlideShowType)1; 
       PowerPoint.SlideShowWindow sw = sst1.Run(); 


       sw.Height = (panel1.Height) - 64; 
       sw.Width = (panel1.Width) - 130; 

       IntPtr formhWnd = FindWindow(x, "Form1"); 
       IntPtr pptptr = (IntPtr)sw.HWND; 
       screenClasshWnd = FindWindow(x, "screenClass"); 
       SetParent(pptptr, panel1.Handle); 

       this.Focus(); 

       this.application.SlideShowEnd += new Microsoft.Office.Interop.PowerPoint.EApplication_SlideShowEndEventHandler(SlideShowEnds); 
      } 
     }

最简单的方法是使用PowerPoint Interop名称空间。你可以在MSDN site上阅读。一个警告，是它需要你安装PowerPoint。所以，如果这将用于商业软件，那么这将是没有实际意义的，因为客户不得不购买PowerPoint。但是对于许多任务来说，它很漂亮，而.NET 4.0使得MS Office的工作变得简单。
