>Your question about memory leaks is really only relevant because you have not made the form clean up its space on destruction. If you use AddObject the way it is intended then the form will automatically destroy the objects added. However, if you are using the array technique you described then YOU must clean up after yourself as the objects created are not truly objects contained in the form but rather are objects to which the form holds a reference. This is the difference between containership and aggregation, the array is using aggregation while the simple AddObject is using containership.

Hilmar's method of using AddObject DOES work correctly, without need to clean up yourself. VfP unfortunately modifies the names of the objects it adds to the form, so the RemoveObject does not find them again - but they are still in the Controls array & are correctly cleaned up on releasing the form.
