Perl keyboard hook or trap for out of focus key strokes

I want to write a program in PERL that will be able to detect my keyboard input even if my perl consol window is out of focus. I am creating an implied prompt program so depending on the window in focus I can run scripts based on my key combinations, keywords, and the title text of the window. Sort of a "hidden prompt" that will be very useful to me.

1) I need to be able to get the title bar text of the window in focus.
2) I need to be able to "trap" or "hook" the keyboard input.

I want to use Win32::GUI or maybe Win32::API to get the title text. Just need the code to get the title text of the window in focus by the system.

# Thank you for any help.

Open in new window

perl script_name.pl explorer

would print the title for all the explorer windows open.
hope this helps.

use strict;
use warnings;
use Win32::API;
use Win32::API::Callback;
my $getwindowtext = Win32::API->new( 'user32', 'GetWindowText', 'NPN',+ 'N' );
my $enumwindows = Win32::API->new( 'user32', 'EnumWindows', 'KN', +'N');
my $title = shift;
$title = qr/\Q$title\E/i;#
my $cb = Win32::API::Callback-> new( 
        sub {
            my $hwnd = shift;
            my $text = " " x 255;
            my $length = $getwindowtext->Call( $hwnd, $text, 255 );
            $text = substr( $text, 0, $length );
            if ( $text =~ $title ) {
                print "$text\n";
        }, "NN", "N",
my $ret = $enumwindows->Call( $cb, 0 );

Hello and thank you for your reply. I would need the title of all the windows open, not just explorer windows.

That is: I would need to know the title of the in focus window, even if it isn't an explorer window. Also need notepad, consol, browser, and so forth.

I came accross this code but am not sure how to impliment it. Any ideas?

It's a system wide keyboard hook which is what I am looking for.

For use with win32::API ?

SetWindowsHookEx(WH_KEYBOARD_LL, (HOOKPROC)FilterFunc, GetModuleHandle(NULL), 0);

Can that be used with win32:API and if so, how? Just need a simple example and way to capture keyboard input. Seems simple enough but I need help.

It seems that needs to be in a DLL to be able to hook system wide hooks, else it would only be a thread hook.

Still waiting for more on this...

The answer to this question is simple: Use another programming language like C++. :-)
