C# ActiveX控件开发,打包cab安装部署,含源码及全过程开发文档.doc

1. 问题场景 在C/S架构的系统中，客户端要实现某些业务功能，可以通过安装相关的应用程序集来方便的实现。同样的需求，在B/S架构的系统里实现起来却比较困难。因为所有的程序都放在服务器端，客户端只是采用浏览器，通过HTTP协议来访问服务器端。比较成熟的解决办法是开发ActiveX控件安装到客户端，这样客户端的浏览器就可以访问本地的ActiveX控件来执行相关的本地操作。通常开发ActiveX使用C，C+或VB开发，本文将要谈论的，就是使用C#开发一个ActiveX控件。3. 注意的地方，C#开发的ActiveX控件只可在装有Framework的系统上才能用。2. 开发工具Visual Studio 2010.NET版本：2.0开发语言：C#3. ActiveX控件项目创建(1)， 新建一个【Windows窗体控件库项目】，项目名为ActiveXDemo选择.NET Framwork2.0版本，因为.Net2.0安装文件只有20多M，客户端容易接受，而且如今多数家用电脑都装了.Net2.0(2)，需要更改两个地方的设置，选中刚创建的ActiveXDemo项目：1).右键选择“属性 应用程序 程序集信息”设置，勾选“使程序集 COM 可见”：2). 右键选择“属性 应用程序 生成”设置，勾选“为COM 互操作注册”（注意，此处如果是在debug状态下修改的，那么在调到release状态下还需要再设置一次）：4. ActiveX控件功能添加(1)，添加一个用户控件(2)，为了使该用户控件作为一个ActiveX控件进行使用，还需要做以下修改：首先，为控件类MiugoX.cs添加GUID，这个编号将用于B/S系统的客户端调用时使用（可以使用 工具-创建GUID 菜单创建一个GUID）：Guid(DF0769A5-99D3-4BE0-90B8-91C65A92118C), ProgId(ActiveXDemo.MiugoX), ComVisible(true) public partial class MiugoX : UserControl, IObjectSafety / DF0769A5-99D3-4BE0-90B8-91C65A92118C就是?刚?刚?创建的?Guid(3)，为了让ActiveX控件获得客户端的信任，控件类还需要实现一个名为“IObjectSafety”的接口。先创建该接口（注意，不能修改该接口的GUID值）：添加一个接口IObjectSafety，实现该接口的目的就是提高程序的安全性，以便客户端IE在不更改设置的情况下可以预行该ActiveX控件。接口成员如下：using System;using System.Runtime.InteropServices;namespace ActiveXDemo 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); (4)，用户控件MiugoX.cs需要继承并实现IObjectSafety接口，需要引用using System.Security.Cryptography和using System.Runtime.InteropServices;两个命名空间Miiugo.cs实现的接口成员如下：using System;using System.ComponentModel;using System.Drawing;using System.Windows.Forms;using System.IO;using System.Text;using System.Security.Cryptography;using System.Runtime.InteropServices;namespace ActiveXDemo Guid(DF0769A5-99D3-4BE0-90B8-91C65A92118C), ProgId(ActiveXDemo.MiugoX), ComVisible(true) public partial class MiugoX : UserControl, IObjectSafety #region IObjectSafety 成员 private const string _IID_IDispatch = 00020400-0000-0000-C000-000000000046;

break; default: Rslt = E_NOINTERFACE; break; return Rslt; #endregion(5)，按照开发Windows用户控件一样的思路完成该控件的开发，本例中主要实现了三个业务功能，第一是创建文件，第二是获取某目录下的文件，第三是显示“你好，ActiveX”的提示消息。用户控件设计界面：程序功能代码：using System;using System.ComponentModel;using System.Drawing;using System.Windows.Forms;using System.IO;using System.Text;using System.Security.Cryptography;using System.Runtime.InteropServices;namespace ActiveXDemo Guid(DF0769A5-99D3-4BE0-90B8-91C65A92118C), ProgId(ActiveXDemo.MiugoX), ComVisible(true) public partial class MiugoX : UserControl, IObjectSafety #region IObjectSafety 成员 /IObjectSafety 成员代码省略，请参考第(4)段 #endregion public MiugoX() InitializeComponent();
