Win32::Process::Hide did not return true value

Abhijit10089 has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,

I am working on a script to hide a process using Win32::Process::Hide but whenever i execute the below written code an error: "Win32/Process/Hide.pm did not return a true value at line 5".

#!/usr/bin/perl

use strict;
use warnings;
require Win32::Process::Hide;
use Win32::Process;
use Win32;

my $processObj;
my $filePath = $ARGV[0];
$filePath =~ s/\\/\\\\/g;
sub ErrorReport{
    print Win32::FormatMessage( Win32::GetLastError() );
}

Win32::Process::Create($processObj,
                       "$filePath",
                       "",
                       0,
                       NORMAL_PRIORITY_CLASS,
                       ".")|| die ErrorReport();
                       
1;

I am using Strawberry Perl 5.16.3.1-32bit, and have installed the Win32::Process::Hide.

Can some one please let me know what i am doing wrong?

Thanks,

Abhijit

I think that error (or is it merely a warning ?) is normally avoided by adding `1;` below the end of the code in the .pm file. That is, in Hide.pm, try changing: `Win32::Process::Hide::HideProcess(); __END__` [download] to `Win32::Process::Hide::HideProcess(); 1; __END__` [download] Cheers, Rob	[reply] [d/l] [select]

I think that error (or is it merely a warning ?) is normally avoided by adding 1; FWIW, it does this by design, when it fails to hide perl.exe, it doesn't return true, so require warns	[reply]

Thanks for your reply, but even after adding 1; at the end of Hide.pm at location "C:\strawberry\cpan\build\Win32-Process-Hide-1.85-ADEtkQ\lib\Win32\Process\" & all other sub-directories of "C:\strawberry\cpan\build\Win32-Process-Hide-1.85-ADEtkQ\" but still receiving the same error. Any Other suggestions?	[reply]

Just tried the same code in Windows XP worked fine for Win32::Process::Hide but still the process was the TaskManager. Any other suggestions on how to hide the process from windows or hide it from other processes like running in a VM of its own.	[reply]

Thanks for your reply, but i am using Windows 7 with no antivirus installed. And i know hiding process is nefarious, but I need to run a program twice in the same system(which wont work until one of those process is hidden)	[reply]
