Win32::OLE->GetActiveObject(progid)
Creates an object for a currently active instance of a server, if one
exists. If the server is registered, but no instance of it is running, the
method returns undef. If the server is not registered, the method
will croak.
You should probably call GetActiveObject inside an eval
so that you can do exception handling in the event that the
server is unregistered or is not currently running. If the method
returns undef, you can just create a new instance of the server
and the object with new.
