关于子菜单自绘

[蜗牛的信仰]

HMENU hSubPopupMenu2;//子菜单
hMenu = LoadMenu(hInst, MAKEINTRESOURCE(IDC_NOTO));       //载入资源菜单
hPopMenu = GetSubMenu(hMenu, 0);     //获取菜单
long lsubMenuID = 0;

InsertMenu(hPopMenu, 3, MF_POPUP|MF_BYPOSITION|MF_OWNERDRAW, (UINT)hSubPopupMenu2, "xxx");/*插入子菜单*/

AppendMenu(hSubPopupMenu2,MF_STRING|MF_ENABLED, IDM_TEST, "temp");//在子菜单hSubPopupMenu2中加入菜单项"temp"
lsubMenuID = (UINT)hSubPopupMenu2;
ModifyMenu(hPopMenu, lsubMenuID , MF_BYCOMMAND|MF_OWNERDRAW, lsubMenuID , "temp1");//添加自绘MF_OWNERDRAW
.

请问:
在WM_DRAWITEM消息中,如何自绘子菜单hSubPopupMenu2呢?要保留hSubPopupMenu2子菜单中的"temp"菜单项
