I'm trying ot read .doc file with ruby, I use win32ole library.
IT my code:
require 'win32ole'
class DocParser
def initialize
@content = ''
end
def read_file file_path
begin
word = WIN32OLE.connect( 'Word.Application' )
doc = word.activedocument
rescue
word = WIN32OLE.new( 'Word.Application' )
doc = word.documents.open( file_path )
end
word.visible = false
doc.sentences.each{ |x| @content
I kick off doc reading with DocParser.new.read_file('path/file.doc')
When I run this using rails c - I don't have any problems, it's working fine.
But when I run it using rails (e.g. after button click), once in a while (every 3-4 time) this code crashes with error:
WIN32OLERuntimeError (failed to create WIN32OLE object from `Word.Application'
HRESULT error code:0x800401f0
CoInitialize has not been called.):

Aditionaly, this code read doc file successfully, but after a few seconds rails crashes: see this gist
What is my problem? How can I fix it? Please, help!
