这样修改菜单项有错吗？

[huangxiaoke2000]

BCMenu menu,*pSubMenu;
CString strItem;
if (!menu.LoadMenu(IDR_MAINFRAME)) return;
if (!(pSubMenu = (BCMenu *)menu.GetSubMenu(0))) return;

pSubMenu->SetMenuDrawMode(OPTIONS_MENU_STYLE_XP);
pSubMenu->GetMenuText(15, strItem, MF_BYPOSITION);

if(strItem == "解除任务栏")
{
pSubMenu->ModifyMenu(15, MF_BYCOMMAND | MF_STRING , 15,"锁定任务栏");
}
else
{
pSubMenu->ModifyMenu(15, MF_BYCOMMAND | MF_STRING , 15, "解除任务栏");

}

menu.DestroyMenu();

BCMenu这类是继承于CMenu的类，无论怎么都修改不了啊

把MF_BYCOMMAND都改成MF_BYPOSITION
