Simple WIN32 Service Test

Description: This is a simple test to see the status of WIN32 services. On Windows NT4. I have to give barndoor credit for the WIN32::Service reference because today is the first time I saw it. After playing with it, I figured I would try to get all services and their status. One problem: Some services don't seem to return a CurrentState value. I decided to ignore these and only stick with the set that barndoor has provided.
use Win32::Service;
 
 #set up a hash of known service states
my %statcodeHash = (
     '1' => 'stopped.',
     '2' => 'start pending.',
     '3' => 'stop pending.',
     '4' => 'running.',
     '5' => 'continue pending.',
     '6' => 'pause pending.',
     '7' => 'paused.'
);
        
my %serviceHash;

 #go get 'em...
Win32::Service::GetServices("", \%serviceHash);

foreach $key(keys %serviceHash){
     my %statusHash;
     Win32::Service::GetStatus("", "$key", \%statusHash);
     if ($statusHash{"CurrentState"} =~ /[1-7]/){
          print $serviceHash{"$key"} . " is currently " . $statcodeHas
+h{$statusHash{"CurrentState"}} . "\n";
     }
}

    Under this (and I guess all the WIN32:: stuff) are of course the Windows APIs. If you really want to get into all this stuff and play with Windows internals, then an MSDN subscription is well worth the money. (Before you ask, no I don't work for M$). I pulled all the return codes from the service control API's and there's a lot more info in there too if you need it. The WIN32::Eventlog stuff is very useful too. I've used it to scan machines for certain errors and to log important messages centrally for my scripts. Although this module doesn't seem to be able to read logs on other machines it can be used to log failures in your scripts which can be them checked centrally by the administrator using the standard OS tools.

    There's an error in your code. The line:
    Win32::Service::GetStatus("", "$key", \%statusHash);
    should be:
    Win32::Service::GetStatus("", $serviceHash{$key}, \%statusHash);

    -- Frag.

      Thanks, frag ,

      I tried your solution and it gives me a much more complete list. Here's the proof:
