IE瀏覽器安裝Activex插件

一、新建項目—>類庫,取名:ActiveXDemo

二、右鍵項目屬性:應用屬性==>程序集信息=>使程序集Com可見,
生成==>輸出==>爲com互操作註冊；新建接口類取名:IObjectSafety
直接複製代碼

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;//引入命名空間

namespace ActiveXDemo
{
    //[Guid("08B1EA29-0A20-46BE-8EE0-16A7505A317C")]
    //[ComImport, GuidAttribute("08B1EA29-0A20-46BE-8EE0-16A7505A317C")]
    [ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
    [InterfaceTypeAttribute(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);
    }
}

三、爲控件創建GUID：工具→創建GUID，選5，點擊複製

     #region IObjectSafety 接口成員實現（直接複製）
        private const string _IID_IDispatch = "{00020400-0000-0000-C000-000000000046}";
        private const string _IID_IDispatchEx = "{a6ef9860-c720-11d0-9337-00a0c90dcaa9}";
        private const string _IID_IPersistStorage = "{0000010A-0000-0000-C000-000000000046}";
        private const string _IID_IPersistStream = "{00000109-0000-0000-C000-000000000046}";
        private const string _IID_IPersistPropertyBag = "{37D84F60-42CB-11CE-8135-00AA004BB851}";
        private const int INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001;
        private const int INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002;
        private const int S_OK = 0;
        private const int E_FAIL = unchecked((int)0x80004005);
        private const int E_NOINTERFACE = unchecked((int)0x80004002);
        private bool _fSafeForScripting = true;
        private bool _fSafeForInitializing = true;

        public int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions)
        {
            int Rslt = E_FAIL;

            string strGUID = riid.ToString("B");
            pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA;
            switch (strGUID)
            {
                case _IID_IDispatch:
                case _IID_IDispatchEx:
                    Rslt = S_OK;
                    pdwEnabledOptions = 0;
                    if (_fSafeForScripting == true)
                        pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER;
                    break;
                case _IID_IPersistStorage:
                case _IID_IPersistStream:
                case _IID_IPersistPropertyBag:
                    Rslt = S_OK;
                    pdwEnabledOptions = 0;
                    if (_fSafeForInitializing == true)
                        pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA;
                    break;
                default:
                    Rslt = E_NOINTERFACE;
                    break;
            }
            return Rslt;
        }

        public int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions)
        {
            int Rslt = E_FAIL;
            string strGUID = riid.ToString("B");
            switch (strGUID)
            {
                case _IID_IDispatch:
                case _IID_IDispatchEx:
                    if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_CALLER) && (_fSafeForScripting == true))
                        Rslt = S_OK;
                    break;
                case _IID_IPersistStorage:
                case _IID_IPersistStream:
                case _IID_IPersistPropertyBag:
                    if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_DATA) && (_fSafeForInitializing == true))
                        Rslt = S_OK;
                    break;
                default:
                    Rslt = E_NOINTERFACE;
                    break;
            }

            return Rslt;
        }
        #endregion
    }
}

四、製作成安裝文件
新建項目——其他項目類型——安裝和部署——安裝項目

五、右鍵安裝項目——添加——項目輸出

將我們的項目ActiveXDemo設爲主輸出；
主輸出文件上右鍵——屬性；將Register屬性設爲vsdrpCOM；

重新編譯安裝項目，打開安裝項目所在目錄，雙擊setup.exe文件或ActiveXDemoSetup.msi文件可以將瀏覽器插件安裝到你的電腦；

六、使用ActiveX插件
新建一個Web項目或者一個Html文件，在需要使用瀏覽器插件的頁面上加入以下代碼：
其中classid是新建的GUID編碼

<body>
    <object id="csharpActiveX" classid="clsid:08B1EA29-0A20-46BE-8EE0-16A7505A317C" width="100" height="150"></object>
    <!--<object classid="clsid:08B1EA29-0A20-46BE-8EE0-16A7505A317C" codebase="bin/setup.exe"
            width="200" height="40" id="helloBossma"></object>-->
    <form id="form1" runat="server">
        <div>
            <input type='button' onclick='csharpActiveX.Test()' value='我是按鈕' />
        </div>
    </form>
</body>
<script type="text/javascript">
    var objCard = document.getElementById("csharpActiveX");

    if (objCard.object == null) {
        alert("csharpActiveX插件未安裝！");
    }
    else {
        alert("已檢測到csharpActiveX插件！");
    }
</script>

運行如下：
