I have built an online tracking system for requests my department receives. Due to the nature of the application, I have to open the database connection using Optimistic Concurrency. This works just fine most of the time, but sometimes two people end up trying to make changes to the same record at the same time giving me an error of "Optimistic Concurrency Check Failed". It is an odbc error message. I&#039ve tried to trap this error so I could handle it, but I can&#039t seem to do it. Any ideas? Thanks in advance.
