一、试验内容

1.创立一个菜单，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“开启〞、“保存〞、“画图〞、“退出〞等菜单项选择项；“计算〞菜单包含“总和〞、“方差〞、“均方根〞等菜单项选择项；“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。3.若在用户区内按下鼠标左键，则动态创立一个包括“删除计算总和〞、“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。?4.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。二、试验仪器电脑一台

三、试验原理（主要程序代码及解释）1、创立菜单：

?????

定义菜单：在资源描述文件中定义。POPUP语句，并可以包含子菜单。在头文件中定义菜单项标识所对应的数值。

加载菜单资源。在窗口类中加载菜单：wcex.lpszMenuName

动态的创立菜单：调用CreatMenu创立空的弹出式菜单，调用AppendMenu插入菜单项阻止和激活菜单项MF_ENABLED、MF_GRAYED

修改菜单项：ModifyMenu(hmenu,IDM_FANGCHA,MF_BYCOMMAND,IDM_nihe,\线性拟合\);

2、画图：WM_PAINT

3、鼠标点击事件：WM_LBUTTONDOWN、WM_RBUTTONDOWN4、光标和图标：?创立资源ico、cur

?在cpp文件中调用wcex.hIcon=LoadIcon(hInstance,MAKEINTRESOURCE(IDI_ICON1));
