动态创建菜单步骤：
1创建一个基于对话框的应用程序
2在对话框的头文件中声明一个CMenu类对象m_Menu；
3打开Resource.h,在此文件中定义命令ID。代码为：#define
ID_MENUCAT
1001
4在对话框的OnInitDialog方法中创建菜单。代码如下：
m_Menu.CreateMenu();
//创建菜单窗口
CMenu m_PopMenu;
//定义菜单类对象
m_PopMenu.CreatePopupMenu();
//创建弹出菜单窗口
m_Menu.AppendMenu(MF_POPUP,(UINT)m_PopMenu.m_hMenu,"动物");//插入菜单
m_PopMenu.AppendMenu(MF_STRING,ID_MENUCAT,"猫");
//插入子菜单
m_PopMenu.Detach();
//分离菜单句柄
SetMenu(&m_Menu);//菜单与窗口关联
5在对话框的头文件中声明菜单的消息处理函数，代码为
afx_msg void
OnMenucat();
6在对话框的源文件中添加消息映射宏，将命令ID关联到消息处理函数中。代码如下:
ON_COMMAND(ID_MENUCAT, OnMenucat)
//关联命令ID和消息处理函数
7最后一步，在对话框的源文件中添加消息处理函数的实现代码
void
CCreateMenuDlg::OnMenucat()
{
MessageBox("猫菜单被按下");
}
