Ross Others have replied and pointed out the method (same as a TDatasource and TDataSet link) Also you should override
procedure Notification(AComponent: TComponent; Operation: TOperation); override; which is called when a component instance is destroyed (so that you can clear your pointer and not leave it 'dangling'), For consistency you should also call TComponent.FreeNotification to make sure you are notified of destruction (if the component you are linked to has a different owner) HTH Neven ----- Original Message ----- From: <[EMAIL PROTECTED]> To: "Multiple recipients of list delphi" <[EMAIL PROTECTED]> Sent: Tuesday, November 11, 2003 9:47 PM Subject: [DUG]: Basic question on custom components > Hi, I'm trying to write my first custom component and have come across a > problem I'm positive it's common and easy to solve - but I'm not familiar > with how. > > I have a form with an existing custom component on it (written in the past > by someone else).
