创建一个基于对话框的工程，工程名为CreateMenu

为该对话框增加一个文件菜单项和测试菜单项，如下图所示

测试菜单项至少要有一个子菜单项
在对话框属性中关联该菜单
在resource.h中增加一个ID_TESTMENU宏
#define ID_TESTMENU 5000

在对话框中添加一个Button按钮，建立消息映射，编辑代码如下

void CCreateMenuDlg::OnButton1()  {     // TODO: Add your control notification handler code here     char buf[2];     //获取顶级菜单     CMenu* pMenu=GetMenu();     //获取1级菜单     CMenu* pFileMenu=pMenu->GetSubMenu(0);     CMenu* pTestMenu=pMenu->GetSubMenu(1);     //添加2级菜单     if(pTestMenu->GetSafeHmenu()==NULL)          return;     //添加一个2级弹出菜单，将"文件"菜单项作为该菜单的子菜单     pTestMenu->AppendMenu(MF_POPUP,(UINT)pFileMenu->m_hMenu,"文件");     //添加一个2级弹出菜单，该菜单的子菜单为空     pTestMenu->AppendMenu(MF_POPUP,(UINT)pTestMenu->m_hMenu,"测试");     //添加10个2级普通菜单     for(UINT m_ID=1;m_ID<=10;m_ID++)     {         itoa(m_ID,buf,10);         pTestMenu->AppendMenu(MF_SEPARATOR);         pTestMenu->AppendMenu(             MF_STRING,m_ID+ID_TESTMENU,"2级菜单"+CString(buf));     }       //添加n级菜单     CMenu* pnMenu=pTestMenu->GetSubMenu(2);     pnMenu->AppendMenu(MF_POPUP,(UINT)pnMenu->m_hMenu,"3级菜单");     for(int i=0;i<5;i++)     {         pnMenu=pnMenu->GetSubMenu(0);         if(pnMenu==NULL) return;         itoa(i+4,buf,10);         pnMenu->AppendMenu(             MF_POPUP,(UINT)pnMenu->m_hMenu,buf + CString("级菜单"));     }     pnMenu->GetSubMenu(0)->AppendMenu(         MF_STRING,ID_TESTMENU,"9级菜单"); }

响应单击菜单的事件
添加OnCommand的消息映射，编辑代码如下

BOOL CCreateMenuDlg::OnCommand(WPARAM wParam, LPARAM lParam)  {     // TODO: Add your specialized code here and/or call the base class     UINT uMsg=LOWORD(wParam);     char buf[2];     if(uMsg==ID_TESTMENU)     {                 MessageBox("HELLO!");     }     for(UINT i=1;i<=10;i++)     {         if(uMsg==ID_TESTMENU+i)         {             itoa(i,buf,10);             MessageBox("HELLO! " + CString(buf));         }     }     return CDialog::OnCommand(wParam, lParam); }
