Ed,
Are these declarations created by Delphi or are you the one who has put them into the code manually? >From what I have read; if you close the sub form its tedit (the one on the sub form) is deallocated automatic because when you drop a control onto a form its owner property is the parent control (be it a form or a panel) so when the form is freed or destroyed it automatically frees all the components and their "dependants" with it. This is true weather you have assigned its variable (in code) to another control or not. Maybe if you explain what you want to achieve with this? J PO Box 627 00502 Karen, Nairobi, Kenya.

Is it automatically unassigned, if not does it get cleaned up when the main form closes. Should I in the onclose event of the subform do mainform.edit1 := nil; All advice welcome Best wishes Ed.
