Is removing handler is mandatory ?

Question asked by Jerome De San Nicolás on Jun 25, 2019

Hi guys,

I am playing with events handles in and I have a question about best practice.




To quickly explain :


I have a form with an event handler at load 

I do stuff 

I close the form

(all of this is working fine)



I do not remove the handler before closing the form. Do I really need to call a RemoveHandler before closing the form ? and why ?
