Hello monks,

can't get my way out the following : 

  $class = "winmgmts:{impersonationLevel=impersonate}\\\\$key\\Root\\c
+imv2";
  $process_info = Win32::OLE->GetObject( $class ) || warn "\n shit";
  
  my $cnt = 0;
  foreach my $process ( sort { $a->{Name} cmp $b->{Name}} 
    in( $process_info->InstancesOf( "Win32_Process" ))) {

    print LOG $process -> {Name} . "\n";
    print LOG $process -> {ProcessID} . "\n";
    print LOG $process -> {ExecutablePath} . "\n\n";
  }

The thing is 

$process -> {ExecutablePath}

[download]

can be empty (that causes the warning if I'm right). I can't test

if ( "" ne $process->{ExecutablePath} ) {
  ...  
}

[download]

cos warning again!

Hope someone can point out what am doing wrong.
Thanks

Have a nice day.
