可视化实验二实现Windows应用程序对键盘与鼠标的响应

1、Visual C+面向对象与可视化程序设计实验二实验报告一、实验目的1、使用API函数编制包含各种资源的Windows应用程序； 2、实现Windows应用程序对键盘与鼠标的响应。二、实验内容1、问题描述：（1）创建一个菜单，其中有三个菜单项，分别为“文件”、“计算”和“帮助”，其中，“文件”菜单项包含“打开”、“保存”、“画图”、“退出”等菜单选项；“计算”菜单包含“总和”、“方差”、“均方根”等菜单选项；“帮助”菜单项包含“计算总和帮助”、“计算方差帮助”和“计算均方根帮助”以及“关于”等项 。（2）若单击“画图”菜单项，则绘出P103图形。若在用户区内按下鼠标左键，则动态创建一个包括“删

2、除计算总和”、“添加计算平均值”和“修改计算均方差”三个菜单项的弹出式菜单，由此菜单控制“计算”菜单中菜单项删除、添加与修改。（要求新的弹出式菜单开始时不可用，按下右键后变为可用。） 单击“修改计算均方差”菜单项后，“计算”菜单下的“计算均方差”项改为“线性拟合”，单击“添加计算平均值”菜单项后，“计算”菜单中添加上了“计算平均值”菜单项 。 （3）将光标设定为自己名字中的某个字、图标设定为自己名字中的另一个字。 2、应用程序中所用到的资源、消息，简介主要函数的功能；3、程序实现 4、操作结果三、程序代码#includewindows.h#includeE08700212叶孙晓.hHMENU
