Clearing objects

[=?Utf-8?B?UmljYXJkbyBGdXJ0YWRv?=]

for years, in every form i create in VB .Net 2005, in the FormClosing event i
insert the following code:

GC.Collect()
GC.WaitForPendingFinalizers()

but now i'm creating an application that has a very complex form and i
notice that the first time that i use that form in the application the form
opens fast, but after that it opens very slowly. I can only think that the
problem has to do with cleaning the variables/objects. Does this code, that
i've been inserting is the right one to clear objects on a form? is the
correct form to do it or does someone has a better option or can you give me
an hint for code optimization in this aspect?

My thanks in Advanced

Hello Ricardo

It shouldn`t be necesary to call the GC at all , so remove this code unless
you have a verry good valid reasson to do so
the GC is optimized for best performance by MS , interfering with it`s
collection mechanism wil mostly hurt your applications performance

Ricardo,

I am curious who adviced you to do that, as it is stated to be completely
wrong.

Like as Michel wrote there can be reasons, and therefore you can use it.

But certainly not in the way you do, normally you should not even use the
FormClosing event.
(mostly that event is only used to set something and as well only as it is
really needed something as e.cancel = true)
