对话框的菜单和控件无法使用COMMAND_UI

下面方法最简单、最实用的实现了。

//CXxxDlg.h ///////////////

//重载WM_MENUSELECT
afx_msg void OnMenuSelect(UINT nItemID, UINT nFlags, HMENU hSysMenu);

//CXxxDlg.cpp ///////////////

//消息映射
ON_WM_MENUSELECT()
//消息映射结束

void CXxxDlg::OnMenuSelect(UINT nItemID, UINT nFlags, HMENU hSysMenu)
{
    //CDialog::OnMenuSelect(nItemID, nFlags, hSysMenu);
    
    
    CCmdUI cmdUI;
    CMenu* pMainMenu = GetMenu();
    CMenu* pSubMenu = pMainMenu-> GetSubMenu(nItemID);
    if(IsMenu(pSubMenu->GetSafeHmenu()))
    {
        cmdUI.m_nIndexMax = pSubMenu->GetMenuItemCount();
        for (UINT i = 0; i < cmdUI.m_nIndexMax;++i)
        {
            cmdUI.m_nIndex = i;
            cmdUI.m_nID = pSubMenu->GetMenuItemID(i);
            cmdUI.m_pMenu = pSubMenu;
            cmdUI.DoUpdate(this, FALSE);
        }
    }
    
}

//十分简单，十分好用:)
