Re: developer 2000 forms disable button

Try not to limit functionality to solve a problem.

BEGIN

• Navigate to some independent item (if possible), go_item('b1.t3');

   IF get_item_property('B1.b1',LABEL) = 'That'    THEN
      set_item_property('B1.b1',LABEL,'This');

      set_item_property('b1.t1',enabled,property_true);
      set_item_property('b1.t1',VISUAL_ATTRIBUTE, 'ENABLED');
      set_item_property('b1.t1',navigable,property_true);

      :b1.t2 := NULL;
      set_item_property('b1.t2',VISUAL_ATTRIBUTE, 'DISABLED');
      set_item_property('b1.t2',enabled,property_false);
   ELSE
      set_item_property('B1.b1',LABEL,'That');


      set_item_property('b1.t2',enabled,property_true);
      set_item_property('b1.t2',VISUAL_ATTRIBUTE, 'ENABLED');
      set_item_property('b1.t2',navigable,property_true);

      :b1.t1 := NULL;
      set_item_property('b1.t1',VISUAL_ATTRIBUTE, 'DISABLED');
      set_item_property('b1.t1',enabled,property_false);
