{ Important: Methods and properties of objects in VCL or CLX can only be used
  in a method called using Synchronize, for example,

      Synchronize(UpdateCaption);

  and UpdateCaption could look like,

    procedure tmythread.UpdateCaption;
    begin
      Form1.Caption := 'Updated in a thread';
    end; }

{ tmythread }

constructor tmythread.Create(lb:tedit);
begin
counter:=lb;
count:=1;
inherited create(true);
end;

procedure tmythread.Execute;
begin
  { Place thread code here }
  repeat
  count:=count+1;
  with Critical do begin
  enter;
  counter.Text:=inttostr(count);
  leave;
  end;
  until count=1000;
  end;

end.
