The Report method is used to write into the Event-log and to do that you must first set-up the message you want to write. So I tried the following and it seems to work:

use Win32::EventLog;

$handle=Win32::EventLog->new("System", $ENV{ComputerName})
     or die "Can't open Application EventLog\n";

my %reporthash = (EventType => 'EVENTLOG_INFORMATION_TYPE', Category =
+> 'MyCategory', Data => 'My Raw Data Here', Strings => 'My Null-Termi
+nated Strings Here' . chr(0));

$handle->Report(\%reporthash);

I checked with the Event Viewer and the message was indeed put into the event log.

There are some other fields you can use, such as EventID or Computer or Source. Have a look in the docs to find-out more about these.

You may also want to have a look at Win32::EventLog::Message. It looks to me that you need this to use all fields of the Eventlog (esp. the Source and EventID fields).

If you want to have an easy way to write into the Eventlog, check out Win32-EventLog-Carp.
