Hello all,
I am writing an application in C#, VB.NET which basicaly
has a form with a few pictureBoxes on it and a TabControl
with 3 tab pages - in each one a treeView and a ListView.
In addition it loads a few other dll's as a reference
which should not be memory consuming since each have a
few simple classes.
The thing is - this application can take up to 40,000KB
of memory!!!
Any idea where to start checking? How can I debug and see
what part of my application is responsible for such
memory usage?

One more thing: I did some tests and noticed that even a
simple form with nothing on it can take up to 15,000KB ,
am I doing something wrong???

Thanks,

Haim.

How many controls are you using? Are you displaying images?

That's OK. Remember that the CLR and some larger libraries are loaded for
Windows Forms applications. Don't worry about that too much.

This application is tested to run on terminal servers and
as such this memory usage is unacceptable, one of the
main concerns when using a terminal server is how much
memory each application consumes. Imagine 20 users, each
using this application - that would mean almost Giga of
memory usage for this application alone!
yes, I have more than a few pictures in the final version
but 40MB of memory is just too much.
I understand that for each dll I'm using in my project
the run time loads the same namespaces
(System.windows.forms for example) again and again. is
there a way to share and load each namespace only once?

Thanks again

Haim.
