Win32 service - daemon

Ruby
1

i think i understand how the process works,

require “rubygems”
require “win32/service”
require ‘win32/daemon’
include Win32

Create a new service

Service.delete(‘netcat’)
Service.create(‘netcat’, nil,
:service_type => Service::WIN32_OWN_PROCESS,
:description => ‘just descriptgion’,
:start_type => Service::AUTO_START,
:error_control => Service::ERROR_NORMAL,
:binary_path_name => ‘c:\test\rscript.exe’,
:load_order_group => ‘Network’,
:dependencies => [‘W32Time’,‘Schedule’],

  :display_name       => 'just displayg'

)

this writes to the registry, it also executes the the file as a service
which confuses me because i dont see Service.start anywhere and the
process only last for like 10…

the reason it only last for a few seconds, The service did not respond
to the start or control request in a timely fashion… sounds simple
right? so, i need to add code to the rscript.exe

require “rubygems”
require ‘win32/daemon’
include Win32

class Daemon
def service_main
while running?
sleep 3
File.open(“c:\test.log”, “a”){ |f| f.puts “service is running”
}
# my program will do stuff here ? ? ? Right ???
end
end
def service_stop
exit!
end
end
Daemon.mainloop

this script wont compile with rubyscript2exe

I need my executable to communicate with the service manager… this
daemon script wont compile so now im stumped… idk what else to try…

Ill bump this thread one time before i give up with this method…

Trie to add the following to your daemon (service) script

require ‘RUBYSCRIPT2EXE’ and exit if RUBYSCRIPT2EXE.is_compiling? (see
below)

require “rubygems”
require ‘RUBYSCRIPT2EXE’
require ‘win32/daemon’
include Win32

exit if RUBYSCRIPT2EXE.is_compiling?

the ‘exit if RUBYSCRIPT2EXE.is_compiling?’ will stop the script from
running and compile the code in the a exe file with the required gems.

Good luck

if you are using gem version 1.3, Rubyscript2exe doesn’t work anymore
with this version. Try to downgrade if that’s the case otherwise try
using OCRA it does the same as Rubyscript2exe.
