title: Delphi: what are the 8 mystery components on my form?
body: <p>When I iterate of the controls on my form, I see those which I placed there at design time or run time.  They are all of type TEdit, Tmemo, TComboBox, etc ...</p>
  
  <p>However, there are always exactly eight which I do not recognize. I can skip over them, since they are not of a type which interests me, but I am curios.</p>
  
  <p>I am guessing system controls like min/max/close. Their Name property is empty. Is there any way I can determine what type they are (without explicitly testing for every standard component derived from TWinControl) ?</p>
  
  <p>I am curious - but not yellow ;-)</p>

  <p>Answer:  use <code>ClassName</code> to find out. And i got <code>TGrabHandle</code> for all of them.</p>
  
  <p>Thanks for all the help. +! all round</p>
