I had the same problem and I went to a pool pattern. I never close the forms but only hide them and keep in a Form pool I created. It solves the memory problem but still creates a form handle any time you show again a pooled MDI child.

Hi,
I have the same problem and nothing seem to work, my memory gets bigger and bigger and the client more nervous. Please, if you have any conclusion or suggestions on this issue share it here.
I tried calling dispose on every tiny object I use, I removed all event handlers but no improvement what so ever.
Thanks

MDI Child Form Dispose?
Hi
I am developing an application which has established on MDI Form and there
are many MDI Child forms. My problem is starting when i close the mdi child
forms. They are not disposed from the virtual memory, so it wastes much
memory for the clients. I trigger GC.Collect and i also implemet IDisposable
method for all object that i have created. But when i use a memory profiler
that shows the status of the current object for my application, i see that
there are many native controls and some objects that are not disposed from
the memory
I use C# and .net framework 2.0, so have you met problem as same as my
problem? If you have suggestion it will very helpful for me. Thanks..
Adam, Do you set any methods on your MDI forms as event handlers for other
Adam
Do you set any methods on your MDI forms as event handlers for other
objects outside of the MDI form? If so, that could be extending the
lifetime of your MDI form

Hi,I have one MDI form and all other forms are its children.
Hi
I have one MDI form and all other forms are its children. So if mdi form is
closing that means my application is closing. But my problem is about the
child form in which the native controls and some objects are not disposing.
In the profiler, i have seen that whenever i open a child form, the active
objects get more and more. Although i close and dispose the child form, the
native controls and some object remain alive
When i close a child form, i also set the event handlers of the child form
to null. But as i said before in the memory i see always native controls
much
Did you try that when you add many controls on a child form, and close it,
what happens on the virtual memory? In my application it remains same
Thanks
