John, You are adding controls not components. Components do not have left, top ... properties. Everytime you create a control and add it to another (MyControl.Parent := MyPanel) that control is added to its parents controllist. You can get to this controllist with MyPanel.Controls an indexed list I destroy in my code every control that I add but it shouldn't be necessary - normal control clean up is to free all controls that it owns. hth Mick _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi
