C#制作ActiveX插件

1. 首先新建项目--->类库,取名:ActiveXDemo
2. 
3. 右键项目属性:应用属性==>程序集信息=>使程序集Com可见,
4. 
5. 生成==>输出==>为com互操作注册
6. 新建接口类取名:IObjectSafety,以下代码可直接用,最好不要修改

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;

namespace ActiveXDemo
{
    [ComImport, Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
    [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    public interface IObjectSafety
    {
        [PreserveSig]
        int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);
        [PreserveSig()]
        int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);
    }
}

新建用户控件取名:UserControl1,UserControl1继承自上面新建的接口IObjectSafety,并实现接口(实现接口的方法请复制下面的内容),在类UserControl1添加Guid特性值,利用VS的工具生成guid

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace ActiveXDemo
{
    [Guid("C5BD015D-E2AA-4DD3-AEB7-93D7409FA751")]
    public partial class UserControl1 : UserControl, IObjectSafety
    {
        public UserControl1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("ActiveXDemo");
        }

        public string GetGUID()
        {
            return Guid.NewGuid().ToString();
        }


        #region IObjectSafety 接口成员实现（直接拷贝即可）

        {
            int Rslt = E_FAIL;

            string strGUID = riid.ToString("B");
            pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA;

                    break;
                default:

                    break;
            }

            return Rslt;

            switch (strGUID)

进行简单界面布局:

点击按钮效果见上面代码,还可自己写一个公共方法,我写的是GetGUID(),

生成成功将会生成两个文件:ActiveXDemo.dll和ActiveXDemo.tlb,至此ActiveX浏览器插件制作完成,

以下是如何打包安装ActiveX插件,

我用的InstallShield2010破解版制作安装包

新建InstallScript Msi类型工程

最主要的是在添加文件时候,要把ActiveXDemo.tlb这个文件设为自注册

在生成安装文件时候,可以选择生成适合网络形式的或者单个安装包,在这里我生成了单个安装包,你也可以选择生成网络的

点击生成安装包按钮,生成后如下:

至此,安装包制作完成,我们点击安装后他会自动注册tlb文件.

以下是如何使用ActiveX插件:

新建一个html页面:我取名:TestActiveX.html

内容如下:

<!DOCTYPE html>

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="utf-8" />
    <title></title>
    <Script type="text/javascript">
        function GetGUID() {
          var a=  document.getElementById("ActiveXDemo").GetGUID();
            alert(a);
        }

    </Script>
</head>
<body>
    <object id="ActiveXDemo" classid='clsid:C5BD015D-E2AA-4DD3-AEB7-93D7409FA751' width="350" height="350"></object>

    <input id="Button1" type="button" value="获取guid" onclick="GetGUID()" />
</body>
</html>

注意这里的classid要和你的插件上生成的guid一致才可以
