becuase the main (GUI) thread freezes. You either have to keep the message pump going by calling DoEvent (not recommended) or create a worker thread and do inter-threading communication. There are plenty of tutorials in the forum | [reply] |
Thanks
I have added parallel fork, but still no use. it is taking same time to execute and ui still hangs.
Don't mine could you post any of the Perl Thread implementation example link for easy access, as i could not able to find proper one.

You basically have two options
- Add a progress bar to show the computer is doing something, eventually letting the user cancel the task
- Divide your task into subtasks which can be run from the event loop
The first solution is the easiest to code

I have added progress bar to my script. but gettinng error saying "can not call method SetRange on an undefined value".
I have added use Win32::GUI();
my $progress_bar = $main->AddProgressBar
(
-name => 'ProgressBar',
-pos => 10, 10,
-size => 270, 20,
-smooth => 1,
-vertical => 0,
);
$progress_bar->SetRange(0,50);
$progress_bar->SetStep($y);
$progress_bar->StepIt();

When you post code, you need to put it inside <code></code> tags, which makes it much easier for others to read.
I've posted your code reformatted in a more easier to read format below. However, while reformatting your code, I noticed that it looks like there are some issues with curly brackets. There are some areas that are missing the closing curly brackets and then there are extra curly brackets at the end of your code.
