When I started the program, I set the hiddendelete menu, how can I don't work?

My mainframe :: onCreate () InstallCoolmenus (iDR_mainframe); if (n_systemtype == 1) getMenu () -> getSubmenu (0) -> deleteMenu (id_menu_qingbao, mf_byposition);} setENABLEMENU (TRUE);

ShowControlbar (& M_WndMenubar, True, False); how can I don't work?
