Is the service already registered? (Can you see it in services?) Can you start it with net start ? Are you admin? Uberadmin in vista? Can you start/stop other services? Could you post the code you are trying to start? Could you post the actual command (what did you do when you tried to start the service)? What do you do in your service? You cannot use stdin, stdout, stderr; You don’t see mapped/subst-ed disks, You might not have rights to some files - you are most probably running under SYSTEM user. (Now I see this looks like a confession recipe 😉 J. ---

Hi Jano! thnx for post!! I use winXP, sp2. Yeah service is registered. in “services” the status is “manual” Yes im Admin an yes i can start other Services. so here is my code: * * * require ‘rubygems’ require ‘win32/service’ include Win32 SERVICE\_NAME = “cProjectsOutlookEventsListener3” SERVICE\_DISPLAYNAME = “cProjectsOutlookEventsListener3” if ARGV[0] == “register” #startet den service svc = Service.new svc.create\_service{ |s| s.service\_name = SERVICE\_NAME s.display\_name = SERVICE\_DISPLAYNAME s.binary\_path\_name = 'c:\ruby\bin ’ + File.expand\_path($0) s.dependencies = [] } svc.close puts "Service registriert: "+SERVICE\_DISPLAYNAME elsif ARGV[0] == “start” Service.start(SERVICE\_NAME) puts “Service gestartet” elsif ARGV[0] == “delete” #stop service if Service.status(SERVICE\_NAME).current\_state == “running” Service.stop(SERVICE\_NAME) end Service.delete(SERVICE\_NAME) puts "Service gelöscht: " + SERVICE\_NAME else # schreibe parameterinfo puts “Use: ruby outlook\_rubysvc.rb [option]” puts " options:" puts " register - Registriert und starte den Service" puts " delete - Stoppt und löscht den Service" exit end # hier ist der eigentliche Service-code class Daemon def service\_init # Wartezeit bis der Service richtig initialisiert worden ist sleep 10 end def service\_main fileCount = 0 watchForFile = “C:\findme.txt” while state == RUNNING sleep 5 if File.exists? watchForFile fileCount += 1 File.rename watchForFile, watchForFile + “.” + fileCount.to\_s end end end d = Daemon.new d.mainloop end * * * thnx!

If it does not help, create a log file and store the exception stack trace to it (i.e. enclose everything in begin / rescue. > def service\_main - ``` fileCount = 0 ``` - ``` fileCount = 0 ``` > ``` > watchForFile = "C:\findme.txt" > while state == RUNNING > sleep 5 > if File.exists? watchForFile > > ``` - ``` fileCount += 1 ``` - ``` File.rename watchForFile, watchForFile + "." + fileCount.to_s ``` - ``` begin ``` - ``` File.rename watchForFile, watchForFile + "." + fileCount.to_s ``` - ``` fileCount += 1 ``` - ``` rescue ``` - ``` end ``` > ``` > end > end > > ``` > > end Of course, I assume the program works when run standalone, from the cmd.exe. Access permissions of NTFS might be in the game as well. You may try playing with runas /user:SYSTEM, too. J.
