Handles are destroyed/created all the time. When the Handle is destroyed its value could appear again. > Or you could use this: (name depending on the current time and a random > number if several controls are created in one milli-second) > component.name:='created_at_'+inttostr(trunc(date))+'_'+inttostr(trunc(time*24*60*60*3600))+'_'+inttostr(random(100000)); Bad idea. Think about summer/winter time change or when the user/ntp adjusts time.
