Memory release after form close

[touf]

HI,
In my windows application (VB.NET) when I open a form the memory is
increasing but When I close it the memory doen't decrease (task manager).
each time I close the form and re-open it the memory is increasing.
with the time the machine (512 MO) become slow.
Is there a way to release the memory when closing the form.
Thanks

Do you have any variables in your form that you reference outside the form.
If so, it may be that these variables are being recreated and then
rereferenced every time you open the form but because they are referenced
outside the form they're not being released when you close them.

Touf,

The taskmanager is far from acurate, beside that, what is the problem with
used memory as there is enough to use.

As it is because of your systemadministr ator, then search for this on Google
while using the name Posseth, he has a nice routine (which spent some time),
that keeps system administrators happy. (It is not releasing more memory, as
it is often already released but not showed in taskmanager).

Are you sure one of the components or variabels of your form are used
outside the form ?
have you implemented the using stament with your form ?
You can always force a GC and retrim the proces working setsize, but if
your objects are not marked for collection this will only degrade the
perfomance of your app . see this thread for the code

If you can`t find the problem another solution could be to use seperate
application domains as you have the possibility to unload them and this will
give you the resources back .
