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);

}

运行结果：
