The mistake is most definitely mine...Once I started dissecting the script I
determined the memory surge was coming from a different module I was using
and how I was importing data with it...I realized as Robert states below
that the loading the Win32::GUI DLL takes about 6 mb and after that it's
quite minimal....My apologies..

From: "pcourterelle" <[EMAIL PROTECTED]>
I've created several some simple scripts with Win32::GUI where there is
little more than a window, button and listview and the script is using 6
MB
of memory. The memory usage increase dramatically each time a button is
clicked or the listview is populated. (the buttons do nothing more than
insert a static text item into the listview - literally "bob" The memory
usuage never seems to decrease dynamically when the listview is reset.

I might believe the 6MB, depending on what figure you're quoting as
'memory usage'. On the Win98 box I have in front of me, for a single
blank window I get the follwoing figures (from WinTop):
Allocated: 2632K 3984K
In memory: 1080K 3032K
In use: 848K 2408K
That's close on 6MB of allocated memory - most of which is due to the
DLL's that are loaded:
Name Size
ADVAPI32.DLL 0x10000 Win32 ADVAPI32 core component
COMCTL32.DLL 0x88000 Common Controls Library
COMDLG32.DLL 0x2D000 Common Dialogs DLL
Cwd.dll 0x5000 Perl Cwd
GDI32.DLL 0x26000 Win32 GDI Core component
GUI.dll 0xBD000 Perl Win32::GUI
KERNEL32.DLL 0x7A000 Win32 Kernel core component
MSVCRT.DLL 0x46000 Microsoft C Runtime Library
perl.exe 0xB000 Perl.exe
perl58.dll 0xC6000 Perl core DLL
SHELL32.DLL 0x155000 Win32 Shell common Dll
SHLWAPI.DLL 0x66000 Shell light-weight Dll
USER32.DLL 0x11000 Win32 USER32 core component
VERSION.DLL 0x6000 Win32 VERSION core component
But I agree with Jez that if you're seeing significant (and you don't
say what you think significant is) increases when clicking a button,
then that doesn't sound right. Some (simple) code that exhibits the
problem, some information on what tool you're using to measure the
memory usage, and the figures that you see would allow us to see if
we're seeing the same problem.

Rob.
