系统自动更新AutoUpdate.doc

系统自动更新分为插件更新和系统主程序更新，其中插件更新需要用户手动检查，系统主程序更新在程序启动时检查。系统主程序更新1.可更新除AutoUpdate.exe外的所有文件。一般情况下不更新主程序配置文件，因为主程序配置文件里包含了用户个性化配置，如果更新主程序配置文件就会清空用户配置。2.更新的前提条件如下：（1）需要配置IIS服务器提供Web服务，供AutoUpdate.exe从服务器上下载更新文件。（2）在程序中设置配置文件的路径：00/UFVideo/CSFiles/UpdateXMLFile.xml配置文件的内容如下： 13 00/UFVideo/CSFiles/UpdateMainFiles.zip配置文件提供了两个值一是最新的版本号13，二是更新文件的下载路径00/UFVideo/CSFiles/UpdateMainFiles.zip3.AutoUpdate.exe的工作流程（1）系统登录时主程序检查版本，主程序根据设置配置文件的服务器XML路径 检查比较自身版本和服务器提供版本是否一致，如果低于服务器版本就提示用户更新。（2）用户根据提示同意更新后由主程序启动AutoUpdate.exe，并且在启动时提供三个参数:最新的版本号、主程序名称、下载文件路径。（3）AutoUpdate.exe启动后就开始根据提供的下载路径参数下载更新文件。（4）更新文件下载完成后解压到自身的启动目录中，完成文件更新。（5）更新主程序配置文件中的版本号。（6）重新启动主程序，完成更新任务。using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.IO;using DevExpress.XtraEditors;using System.Threading;using Shell32;using System.Configuration;namespace AutoUpdate public partial class XtraFormUpdate : DevExpress.XtraEditors.XtraForm public XtraFormUpdate(string agr) InitializeComponent();
