1、 西华大学实验报告第 组 . 西华大学实验报告（计算机类）开课学院及实验室：机械工程与自动化 实验时间 ： 年 月 日学 生 姓 名 学 号 成 绩学生所在学院机械工程与自动化年级/专业/班2011级机电 班课 程 名 称高级语言在测控中的应用课 程 代 码6003559实验项目名称简单的MFC应用程序设计项 目 代 码指 导 教 师项 目 学 分一、实验目的1. 理解Windows编程特点；2. 了解MFC应用程序的消息映射、数据映射机制；3. 掌握用AppWizard(exe)创建SDI和MDI应用程序的方法；4. 掌握使用项目工作区窗口的ClassView页面为类添加成员的方法；5. 掌

2、握用ClassWizard映射消息的方法。6. 掌握对话框编辑器的使用方法；7. 熟悉对话框的编程过程及控件的创建和使用方法；8. 掌握静态控件、按钮和编辑框控件的使用方法。二、内容与设计思想上机实践内容：1 设计一个对话框，用于学生成绩的输入，要求能输入学生姓名、学号、性别以及3门课程成绩，单击“求平均”按钮是计算3门课程的平均成绩并显示在上面的静态文本框中。通过单击“测试”菜单下的“成绩录入”子菜单调用该对话框，在该对话框中要用到控件：静态文本、编辑框(单行和多行)、单选框、复选框、组框、按钮等，其运行结果如下：算法设计思想与算法实现步骤等。三、使用环境操作系统：Windowns XP+环
