Windows实验、

1、课程设计(综合实验)报告( 2013 - 2014 年度第 学期)名 称： Windows体系编程 题 目： 课内综合实验 院 系： 计算机科学与技术 班 级： 计科1103 学 号： 201109010307 学生姓名： * 指导教师：* 实验学时： 12学时 成 绩： 日期：2014年 5月 26日第17页一、课程设计(综合实验)的目的与要求1. 理解Windows编程环境下的进程管理机制，能创建一个完成特定功能的进程，能对进程进行信息的获取、终止和保护，实现一个类Windows的进程任务管理器。 11 能够完成创建进程的功能，打印输出新建进程ID。12 获取当前系统进程信息，列出可选显示

2、进程信息项，根据选择显示输出进程信息。13 终止任意进程并获取退出代码。14 具体实现技术不限。2. 理解Windows编程环境下的线程同步机制，掌握线程同步的方法，包括临界区对象、事件内核对象、互锁函数等方法，并能用线程同步解决经典的线程同步问题，体会多线程编程。. 2.1 为每个哲学家产生一个线程，设计正确的同步算法2.2 每个哲学家取得一双筷子开始用餐后，即时显示“Dining”和该哲学家的自定义标识符以及餐桌上所有几位哲学家标识符及其所坐的位置。2.3 设定共有5个哲学家需用餐。每位用餐耗时10秒钟以上。2.4 多个哲学家须共享操作函数代码，最好有界面展示。3. 该实验为综合实验，通过

3、该实验，使学生学习使用visual c#进行简单的综合功能的系统开发。巩固Windows编程的基础知识，增加学生的利用图形子环境编程的综合能力，包括界面设计能力、使用GDI,GDI+或WPF的能力等。 3.1 利用GDI，GDI+或WPF实现简单绘图器，选其中一种即可，编程环境不限。 3.2 实现绘制线条、矩形、圆形，可改变线条或填充的颜色。2、 设计（实验）正文1、源代码： using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawi
