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>
