Have you thought about setting up a separate thread when the process first
starts?
It could do all the work and dump output into a socket or pipe. The
receiving thread then just checks the socket (I have more experience
there, than with pipes) occasionally for waiting input.

Subject: Re: [perl-win32-gui-users] File Monitoring Script
The problem I was having was how to get any new line back to the GUI. Once
you do a Win32::GUI::Dialog, the perl script basically stops, and you can
only work with the GUI. How would I set up a Sub to run in the background
and update the GUI with any changes? I first thought of an alarm, but
that
function is not implemented on Win32 v5.6.1 (Activestate). I tried to use
AddTimer, but that just seemed to do absolutely nothing once it hit the
$file->read part (File::Tail). Is my only option to thread something off?
I'm farily new to both Perl and Win32::GUI, so if this sounds ridiculous
please excuse me.
Thanks.
Len.

One way of updating the ListView is to InsertItems for every new line
added
to the file your application is watching. If, for example, you are
retrieving each
line as a string then you could also test for your "Failed" substring and
consequently change the color of the list item. Please see the
documentation
that came with the module or the online version here:
