if you mean like such:
dim ctl2 as new ctl1
then, no, because the control is dynamically created during runtime.
When I set the new control equal to the existing one, both are disposed of when the 2nd is removed from the form.
like such:
NewForm_Load Event
dim ctl2 as new controltype
ctl2 = OrigForm.Controls(ControlIndex)
then, on NewForm.Close, ctl2 and OrigForm.Controls(ControlIndex) are destroyed.
