I am trying to build an windows service ( WIN XP SP-2) using the
Win32-service package for ruby.
This service is supposed to pull some stock data from yahoo site
every minute and print to screen.
For this objective to be accomplished i have the following three files
1> yahootickerpull.rb
This has a class Yahooticker and a method called refresh.
2> datasrc_ctl.rb
This has code for controlling the service like
install,start,stop,delete etc..... Here i utilize the win32/service
3>yahootickerservice.rb
Here i require the yahootickerpull and win32/service ... and override
the "Daemon" class onto "YDaemon" class .
In the "service_init" method i create a Yahooticker object .... and in
the service_main method i call the refresh method of this object.
This is the blue print.
===============================
problem is i get an error:
C:\mooney.com\historicalqoute\yahooticker>ruby datasrc_ctl.rb start
VERSION: 0.5.2
datasrc_ctl.rb:61:in `start': The service did not respond to the start
or control
request in a timely fashion. (Win32::ServiceError)
from datasrc_ctl.rb:61
==================================
I suspected the win32/service .... but the example code that comes
with the package tdaemon.rb and tdaemon_ctl.rb...... works perfectly
.....
So i suppose i am doing some fundamental mistakes....
