In my experience, the latter is true. We would consistently get errors when multiple threads attempted to write from multiple threads and have not had any problems when syncronizing. In that case the problem was that one thread would add something while another checked to see if it existed and added if necesary. That's exactly what happens if your code is myHash[key] = value; if key is not in the hash, it is added automatically, otherwise the value is just assigned. ===== Philip - http://blogs.xcskiwinn.org/panmanphil "There's a difference between righteous anger and just being crabby" - Barbara =================================== This list is hosted by DevelopMentorŪ http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
