Hello, this is probbly a very basic question, I am having virtual memory probelms in my app.

First when the program loads in one of the modules i have:
              PUBLIC X1(500) as NEW Form1

Then i have  the program load those forms not all of them, but typicly anywhere from 4 to 100 of those, but i want the extra for future use.

Also I have listviews in each one storing about 60 lines of data with 4 or 5 sublists.

Anyway, could any of that be the reasion for my virtual memory problems?  And if so what do you suggest I do?

What kind of virtual memory probelms? Any error message?

If there is problem such as not enough memory, put some more.

And also, do the following will save some memory:

declare this in the module
PUBLIC X1(500) as Form1

when you want to load one more form1, do
set x1(xxx) = new form1

I am using that:

declare this in the module
PUBLIC X1(500) as Form1

when you want to load one more form1, do
set x1(xxx) = new form1

Thats not an issue, Windows is giving me low virtual memory errors.

As what I said, it will save some of your memory, save only. Now, tell me how many memory you got on your computer, 64? 128?

Should be enough, try to load only 10 forms, see what happens, basically, unless you used too much memory, you shouldn't see virtual memory problem. And also, try to increase the virtual memory in your computer see if that's solve the problem.

I have tried that, under task man, it just loads just at a minimal amount of ram, then the ram increases at a slow rate and this is a program that is needed to run 24x7 for well... for ever on an automated system that will be stored in a rack.

What is your program doing that it needs 500 forms?

It is running code in each node (form).

That seems very ineffecient to use a form just to house some code.  Does each piece of running code need a visual interface?

well, each form does a winsock function call that pings its responsible host to make sure its active.  Sometimes it is supose to ping it every second and sometimes there are problems, i don't want every "node" or from to have to wait until the other is done doing what ever.  So this is why i need everything on its own form

I wonder if it would be less memory intensive to have one form with arrays of winsock controls, timers and listviews?  It might be worth trying out.

"...I am having virtual memory probelms in my app."

Just a few tips...If you don't have all the answers, then don't:

1) Post a question in an open public forum.

2) Berate people for asking for further detail.

3) Judge what is or is not revelant to the "problem" when you haven't been able to figure it out yourself.

4) Get frustrated when people take their time to help you.

I will gladly not post any further comments.

Good Luck,
