activex在html里面加载方式

1.打开VS2010，创建一个Windows控件库项目

2.创建一个IObjectSafety接口，防止IE弹出不安全提示

  [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);
    }

3.在项目中添加用户控件，并实现上面接口，并为控件分配一个GUID,在HTML是要用到的

，另外还要引用命名空间：using System.Runtime.InteropServices;

  1. [Guid("0D69FA27-592D-4B7E-BF7D-A0BCDC54D1BC")]//直接创建一个就可以，或用工具，点创建GUID,再复制过来
  2.     public partial class TestUc : UserControl,IObjectSafety
  3.     {
  4.         public string UID { get; set; }
  5.  
  6.         public TestUc()
  7.         { 
  8.             InitializeComponent();
  9.         }
  10.  
  11.         public string Test(string abc)
  12.         {
  13.             UID = abc;
  14.             return "TestUc:This is a " + abc;
  15.         }
  16.         #region IObjectSafety 成员
  17.  
  18.         private const string _IID_IDispatch = "{00020400-0000-0000-C000-000000000046}";

  56.                 default:

  58.                     break;
  59.             }
  60.  
  61.             return Rslt;
  62.         }
  63.  
  64.         public int SetInterfaceSafetyOptions(ref Guid riid, int dwOptionSetMask, int dwEnabledOptions)
  65.         {

  68.             switch (strGUID)
  69.             {
  70.                 case _IID_IDispatch:

  84.             }
  85.  
  86.             return Rslt;
  87.         }
  88.  
  89.         #endregion
  90.     }

4.创建安装程序

在该解决方案上继续添加新工程，选择其他项目类型，选择安装工程

然后设置下属性Register

ActiveX已经做好了，下面开始调用


5.新建一个web项目，新建一个页面，把

  1.  
  2.   
  3.   
  4.    
  5.    
  6.     
  7.     <script>
  8.  function test() {
  9. var obj = document.getElementById("Object2"); var v=obj.Test("小花");//Test就是控件里面的方法，这里的大小写可以忽略 alert(v); var p=obj.UID;//UID就是控件里面定义的属性 }
  10. </script>
  11. <div>
  12.     <input type="button" value="Test" οnclick="test()" />
  13.      <object id="Object2" classid="clsid:0D69FA27-592D-4B7E-BF7D-A0BCDC54D1BC"   width="100"
  14.         height="25"   style="display:none"
  15.         codebase="/lib/setup.exe">       
  16.     </object>
  17.     </div>
  18.  
  19.    
  20.    
  21.

直接运行下，就可以了！
