CMenu menu; ClientToScreen(&point); VERIFY( menu.LoadMenu( IDR_MENU1 ) ); CMenu* popup = menu.GetSubMenu(0);

ASSERT( popup != NULL ); popup->EnableMenuItem(ID_POPUP1, MF_BYCOMMAND|MF_GRAYED);

popup->ModifyMenu(ID_POPUP1,MF_BYCOMMAND,ID_POPUP1, "11"); popup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this );
