C#制作ActiveX插件

1. 首先新建項目--->類庫,取名:ActiveXDemo
2. 
3. 右鍵項目屬性:應用屬性==>程序集信息=>使程序集Com可見,
4. 
5. 生成==>輸出==>為com互操作注冊
6. 新建接口類取名:IObjectSafety,以下代碼可直接用,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);
    }
}

新建用戶控件取名:UserControl1,UserControl1繼承自上面新建的接口IObjectSafety,並實現接口(實現接口的方法請復制下面的內容),在類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 接口成員實現（直接拷貝即可）

進行簡單界面布局:

點擊按鈕效果見上面代碼,還可自己寫一個公共方法,我寫的是GetGUID(),

 

生成成功將會生成兩個文件:ActiveXDemo.dll和ActiveXDemo.tlb,至此ActiveX瀏覽器插件制作完成,

以下是如何打包安裝ActiveX插件,

我用的InstallShield2010破解版制作安裝包

新建InstallScript Msi類型工程

最主要的是在添加文件時候,要把ActiveXDemo.tlb這個文件設為自注冊

在生成安裝文件時候,可以選擇生成適合網絡形式的或者單個安裝包,在這里我生成了單個安裝包,你也可以選擇生成網絡的

 

點擊生成安裝包按鈕,生成后如下:

 

至此,安裝包制作完成,我們點擊安裝后他會自動注冊tlb文件.

以下是如何使用ActiveX插件:

新建一個html頁面:我取名:TestActiveX.html

內容如下:

<!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="獲取guid" onclick="GetGUID()" />
</body>
</html>

注意這里的classid要和你的插件上生成的guid一致才可以
