c#写Activex控件(.Net 2.0)

1、继成一个IObjectSafety.cs，接口代码如下，功能是修改ie安全性
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.ComponentModel;

namespace activex
{
    [
        Serializable,
        ComVisible(true)
    ]
    public enum ObjectSafetyOptions
    {
        INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001,
        INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002,
        INTERFACE_USES_DISPEX = 0x00000004,
        INTERFACE_USES_SECURITY_MANAGER = 0x00000008
    };

    //
    // MS IObjectSafety Interface definition
    //
    [
        ComImport(),
        Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064"),
        InterfaceType(ComInterfaceType.InterfaceIsIUnknown)
    ]
    public interface IObjectSafety
    {
        [PreserveSig]
        long GetInterfaceSafetyOptions(ref Guid iid, out int pdwSupportedOptions, out int pdwEnabledOptions);

        [PreserveSig]
        long SetInterfaceSafetyOptions(ref Guid iid, int dwOptionSetMask, int dwEnabledOptions);
    };
}



2、新建一个windows控件项目
      修改该控件类的Attribute，项目属性勾上为Com  Interop注册。
[
        Guid("627AD403-FA50-4a08-B875-770520865DD6"),
        ComVisible(true)
]

   控件中实现接口代码

   #region IObjectSafety 成员

        private ObjectSafetyOptions m_options =
            ObjectSafetyOptions.INTERFACESAFE_FOR_UNTRUSTED_CALLER |
            ObjectSafetyOptions.INTERFACESAFE_FOR_UNTRUSTED_DATA;

        public long GetInterfaceSafetyOptions(ref Guid iid, out int pdwSupportedOptions, out int pdwEnabledOptions)
        {
            pdwSupportedOptions = (int)m_options;
            pdwEnabledOptions = (int)m_options;
            return 0;
        }

        public long SetInterfaceSafetyOptions(ref Guid iid, int dwOptionSetMask, int dwEnabledOptions)
        {
            return 0;
        }

        #endregion

3、增加html访问代码,codebase为安装Activex控件的Cab包地址,也可以建一安装项目，来让客户下载安装。
<object id="id"
         classid="clsid:627AD403-FA50-4a08-B875-770520865DD6" Width="640" Height="360" codebase="hello.cab">
</object>
