Hi all,
i detail out an issue i am facing while trying to read messages from
outlook via a windows service.
The goal of the code is to scan outlook inbox every 10 minutes and if
any specified file attachment is found ... save it.
The code will be installed as an windows service and scan for the
email automatically.
The service code is fine and runs in background as well but as I call
outlook via win32ole from the service mainloop it does not give me
the inbox with any item.
Can any one lead me to the problem??
the service code
it works like a champ

Sorry for a long code...
The problem is that my log file loooks like this

mailbox spawn succ at : Tue Apr 08 17:30:24 +0530 2008
===========================================
the inbox messagecount is returning 0 messages.
while if i run it without any service deamon via simple code like this
require 'win32ole'
outlook = WIN32OLE.new('Outlook.Application')
mapi = outlook.GetNameSpace('MAPI')
inbox = mapi.GetDefaultFolder(6)
file_c=1
#methods = []
#arrival_time=inbox.Items(1).ReceivedTime
#b=arrival_time.to_a
#puts arrival_time
#require "parsedate.rb"
#include ParseDate
#formatted_date=parsedate(arrival_time)
#p formatted_date
puts "#{inbox.UnreadItemCount}:so many unread messages"
puts "#{inbox.Items.Count}:so many messages"
=======================
i get output like a champ
===============
484:so many unread messages
11398:so many messages
========================
i am battling it out for last couple of days to find why.
and i need help badly.
