Using the results from Win32::Process::Info

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

Hello Monks, I have a small program as below; in the program below which makes use of the win32::Process::info module, i am unable to access the hash it returns. Basically i did not understand from the module on how to access these hash references. Please help me with this.

#!/usr/bin/perl

 use Win32::Process::Info;
    
 $pi = Win32::Process::Info->new ("172.16.222.173", "WMI");

 @pids = $pi->ListPids ();    # Get all known PIDs
 @info = $pi->GetProcInfo ();    # Get the max
foreach $i (@pids)
{
    print $i, "\n";
    @proc = $pi->GetProcInfo($i);
    print @proc , "\n";
    
}

Hi nisha, You can use Data::Dumper. `use strict; use warnings; use Win32::Process::Info; use Data::Dumper; my $pi = Win32::Process::Info->new ("172.16.4.47", "WMI"); my @pi = $pi->ListPids (); # Get all known PIDs print Dumper $pi->GetProcInfo ($_) for @pi; #Get the info` [download] Also take a look at perlref about dereference. updated Prasad	[reply] [d/l]

Re: I've got a hash of hashes how do i get my values out (this one is especially interesting since its output is almost exactly the syntax you'd use to access parts of your struct in a Perl program...)

Hi If you are familiar with reference, try using Data::Dumper `use Data::Dumper; @pids = $pi->ListPids (); # Get all known PIDs @info = $pi->GetProcInfo (); # Get the max print Dumper [ @pids ]; print Dumper [ @info ];` [download] The above code will give a clear picture, then you can access it from the datastructure it shows.
