exe程序嵌入Winform窗体

1.新建winform程序,添加一个Panel控件和一个button控件,winform窗体命名为:Mainform;

2.新建一个类文件,方便引用,命名为:exetowinform;

3.Mainform中cs代码如下:

  exetowinform fr = null;
        private void button1_Click(object sender, EventArgs e)
        {            
            OpenFileDialog Oppf = new OpenFileDialog();
            Oppf.ShowDialog();
            if (Oppf.FileName != "")
            {
                panel1.Controls.Clear();
                fr = new exetowinform(panel1, "");
                fr.Start(Oppf.FileName);
            }
        }
4.exetowinform类文件代码如下:

 public class exetowinform
    {
        EventHandler appIdleEvent = null;
        Control ParentCon = null;
        string strGUID = "";

        public exetowinform(Control C, string Titlestr)
        {
            appIdleEvent = new EventHandler(Application_Idle);
            ParentCon = C;
            strGUID = Titlestr;
        }

        /// <summary>
        /// 将属性<code>AppFilename</code>指向的应用程序打开并嵌入此容器
        /// </summary>
        public IntPtr Start(string FileNameStr)
        {
            if (m_AppProcess != null)
            {
                Stop();
            }
            try
            {
                ProcessStartInfo info = new ProcessStartInfo(FileNameStr);
                info.UseShellExecute = true;
                info.WindowStyle = ProcessWindowStyle.Minimized;
                m_AppProcess = System.Diagnostics.Process.Start(info);
                m_AppProcess.WaitForInputIdle();
                Application.Idle += appIdleEvent;
            }
            catch
            {
                if (m_AppProcess != null)
                {
                    if (!m_AppProcess.HasExited)
                        m_AppProcess.Kill();
                    m_AppProcess = null;
                }
            }
            return m_AppProcess.Handle;
        }

        void Application_Idle(object sender, EventArgs e)

            if (this.m_AppProcess == null || this.m_AppProcess.HasExited)
            {
                this.m_AppProcess = null;
                Application.Idle -= appIdleEvent;
                return;
            }

            while (m_AppProcess.MainWindowHandle == IntPtr.Zero)
            {
                Thread.Sleep(100);
                m_AppProcess.Refresh();
            }
            Application.Idle -= appIdleEvent;
            EmbedProcess(m_AppProcess, ParentCon);
        }
        /// <summary>

        public void Stop()
        {
            if (m_AppProcess != null)// && m_AppProcess.MainWindowHandle != IntPtr.Zero)
            {
                try
