FAR DeActMenuEx(ParamBlk FAR *parm)
{
   MENUID menuId;
   ITEMID itemId;
   Point loc;

   menuId = _GetNewMenuId();
   _NewMenu(MPOPUP, menuId);

   itemId = _GetNewItemId(menuId);
   _NewItem(menuId, itemId, -2, "\\<1st item");

   itemId = _GetNewItemId(menuId);
   _NewItem(menuId, itemId, -2, "\\<2nd item");

   itemId = _GetNewItemId(menuId);
   _NewItem(menuId, itemId, -2, "\\<3rd item");

   loc.v = 10; loc.h = 20;
   _SetMenuPoint(menuId, loc);

   _ActivateMenu(menuId);
   _Execute("WAIT WINDOW 'Menu activated'");
   _DeActivateMenu(menuId);
   _Execute("WAIT WINDOW 'Menu deactivated'");
   _ActivateMenu(menuId);
   _Execute("WAIT WINDOW 'Menu activated'");
   _DeActivateMenu(menuId);
   _Execute("WAIT WINDOW 'Menu deactivated'");

}

FoxInfo myFoxInfo[] = {

FoxTable _FoxTable = {
   (FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
