LOL and head shaking You are absolutely right a simple if(Text != null) was all i needed <g> The book "Java how to program" tells in one of the first chapters that if the user press cancel java will throw an Exception and that they will deal with that problem in chapter 14 about exception handling, so i thought it was because it only would throw an exception and i didn't even try to check if Text was null. Thank You Very Very much. Happy regards Asger
