Corion's post seemed like a good suggestion. I see that you've posted that it didn't work. As Corion has replied, "it doesn't work" is usually a very poor problem description. What code didn't work? What was the input? What was the result? Please see Short, Self-Contained, Correct Example and I know what I mean. Why don't you?.

Note: It's best to reply directly to Corion's posts on this matter. He knows a lot more about it than I.
