使用 ActiveX 在网页内嵌本地程序 ；网页打开上嵌入本地Excel并打开指定文件

1.创建 Windows 窗体控件库项目；

2.修改项目基础配置

     2.1 修改 AssemblyInfo  添加  [assembly: AllowPartiallyTrustedCallers()]   引用 命名空间 System.Security

     

    

   2.2 修改项目程序集信息 ，勾选 “ 使程序集com可见 ”

       

 2.3 修改生成 输出  勾选 “ 使程序集com可见 ”

    

 

3.主代码

using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace Web.Activex.App

    [Guid("71A30280-6AB4-4F29-8C23-B340736B4618")]//此Guid 开发者可自己生成 网页嵌入ActiveX时会使用此Guid
    public partial class UserControl1: UserControl, IObjectSafety
    {
        [DllImport("User32.dll ", EntryPoint = "SetParent")]
        private static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

        public UserControl1()
        {
            InitializeComponent();
        }

        public void OpenExcel(string fileFullName)
        {
            //第一个参数 powerpnt excel  winword  或其它，开发者按自己需要换其它程序的启动命令
            //第二个参数 打开的具体文件的全路径
            var proces = Process.Start("excel", fileFullName);

            if(proces!=null)
            SetParent((IntPtr) proces.Id, panel1.Handle);//获取打开的程序窗口句柄，与本控件内要放置的控件的句柄
        }

4.创建ActiveX安装程序

 

5.软件的  代码部分就算完成了， 现在只要生成安装程序，并且安装到计算机就可以使用了，我们省略安装步骤，

 

6.网页调用此控件

<object id="CardAccessor" 
    classid="clsid:71A30280-6AB4-4F29-8C23-B340736B4618"     
    width="0" 
    height="0">
</object>

 

 

var objCard = document.getElementById("CardAccessor");

objCard.OpenExcel("D://1.xlsx")
