Ok , I have a main form and several sub forms that get called from the main form
In the public of the main form I could have something like this edit1:Tedit; In my subform I have a Tedit on the form In my subform I do this mainform.edit1 := subform Tedit; When I close the subform what happens to edit1 on the mainform ? 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.
