No it won't. In order to do that, instead of creating a separate variable for the DE, use the form variable and AddObject the DE class to it. When the form is destroyed, the associated object should be destroyed. However, if there is a problem, you may have to explicitly release the DE object in the Destroy of the form to avoid dangling object references.

Form.Load
THISFORM.AddObject("oDE","DE")

Form.Destroy
THISFORM.RemoveObject("oDE")
