1. 新建 WindowFormControlLibrary

2. 修改 项目->右键属性->Application-> Assembly Information ->勾选 Make Assembly Com-Visible

3. 修改 项目->右键属性-> Build -> 勾选 Register for Com interop 

4. 控件cs界面, using System.Runtime.InteropServices 命名空间; 类名添加 GUID属性

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 MyActiveX2{    [Guid("07333C44-7CFD-3C64-A540-C476FE80EEF2")]    public partial class demo : UserControl, IObjectSafety    { .....

 

5. 继承IObjectSafety 接口

#region IObjectSafety Members        public void GetInterfacceSafyOptions(int riid, out int pdwSupportedOptions, out int pdwEnabledOptions)        {            pdwSupportedOptions = 1;            pdwEnabledOptions = 2;        }        public void SetInterfaceSafetyOptions(int riid, int dwOptionsSetMask, int dwEnabledOptions)        {            //throw new NotImplementedException();        }        #endregion

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Runtime.InteropServices;namespace MyActiveX2{    [Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]    public interface IObjectSafety    {        void GetInterfacceSafyOptions(System.Int32 riid, out System.Int32 pdwSupportedOptions, out System.Int32 pdwEnabledOptions);        void SetInterfaceSafetyOptions(System.Int32 riid, System.Int32 dwOptionsSetMask, System.Int32 dwEnabledOptions);    }}

6. 网页引用就可以了

7. 安装程序

新建项目-> 安装项目 -> Appliction Folder -> 添加 项目的主输出,并设置Register属性为vsdrpCOM.
