1、网络程序设计报告班级：计算机网络1班学号：200902220110姓名：廖维海所作课题：模拟时钟指导老师：胡庆辉二零一一年六月二十五日（另外：想要该MFC工程文件，在Q：450016913上面留言，到时候发给你！）MFC模拟时钟程序报告一、实验目的：基于学习了MFC的WINDOWS应用程序设计，特别鉴于此，所以用MFC工程编写一个模拟时钟程序，用来巩固自己的知识。该程序初始界面为在屏幕左方有一个指针式钟面，右方有一个矩形框，上面以数字方式显示日期和时间，该时间应与指针显示的时间一致，用菜单选项或按钮设置时间和秒表。二、问题分析：本程序所涉及到的知识点有：时钟指针运动算法、屏幕重绘方法、定时器消

2、息、鼠标消息、菜单命令、对话框、画笔/画刷、显示文字等。指针运动算法和屏幕重绘方法是本程序主要难点所在。三、程序基本要求：（1）为该程序设计一个美观大方的图标。（2）程序界面设计合理，色彩得体大方，显示正确。（3）时针、分针和秒针形象美观，即使各指针重合也可辨认。（4）各指针运动规律正确。由于时间有限，所以设计之初，时钟速度应比实际时间快20倍，即1小时相当于3分钟。（5）数字式时钟的时间显示与指针式时钟显示一致。（6）按下设置时间按钮或菜单项可弹出一对话框，用于设置当前的时间和日期。四、运行环境与参考文献：环境：Windows XP操作系统下的Microsoft Visual C+ 6.0参
