.net - Powerpoint 查看器控件 C#/VB/.NET

Question

谁知道如何制作或下载控件以查看 powerpoint 文档？

我搜索过，但唯一出现的是 this ，这绝对不是免费的。我敢肯定，Microsoft 一定已经有一个控件可以执行此操作。

制作一个控件来做到这一点也很受欢迎。

这里有我一直在处理的问题的解决方案。 如果有人遇到同样的问题，我会在此处留下我经过数小时工作后做出的解决方案。

        [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);
            }
        }
