windows mobile 下创建/隐藏菜单

SHMENUBARINFO mbi;
  ZeroMemory(&mbi, sizeof(SHMENUBARINFO));
  mbi.cbSize=sizeof(SHMENUBARINFO);
  mbi.hwndParent=m_hWnd;
  mbi.hInstRes=::AfxGetInstanceHandle();
  mbi.dwFlags=SHCMBF_HMENU|SHCMBF_HIDESIPBUTTON;//隐藏SIP
  mbi.nToolBarId=IDR_MYMENU;
  SHCreateMenuBar(&mbi)；

HWND hwnd=::SHFindMenuBar(m_hWnd);
  if(hwnd!=NULL)
  ::ShowWindow(hwnd,SW_HIDE);

TBBUTTONINFO tbbi = {0};
   tbbi.cbSize = sizeof(TBBUTTONINFO);
   tbbi.dwMask = TBIF_LPARAM | TBIF_BYINDEX;                
   ::SendMessageW(mbi.hwndMB, TB_GETBUTTONINFO,0, (LPARAM)&tbbi); //0为SK1，1为SK2(即左右软键)
   g_hMenu = (HMENU)tbbi.lParam;//g_hMenu为全局变量，这样就可以在任何地方隐藏子菜单了

::SHEnableSoftkey(mbi.hwndMB,0,TRUE,FALSE);

HMENU hMenu; 
    HWND hwndMenuBar = ::SHFindMenuBar(m_hWnd); //m_hWnd是窗口句柄
    tbbi.cbSize = sizeof(tbbi); 
    tbbi.dwMask = TBIF_LPARAM|TBIF_BYINDEX;
    //第三个参数1表示右菜单，为0表示左菜单
    ::SendMessage(hwndMenuBar, TB_GETBUTTONINFO, 1, (LPARAM)&tbbi); 
    hMenu = (HMENU)tbbi.lParam; //hMenu这个句柄就是菜单操作常用的句柄了，获得这个句柄非常有用。
    DWORD ack =    CheckMenuItem(hMenu,ID_STARTUP,MF_BYCOMMAND|MF_CHECKED);
