I am interested in using TThread to parse a text file and populate a database table, is there anyone that can give me a few pointers as to how this could be done? Also if there are any traps to watch out for? Also, is it a good idea to handle exceptions within the thread?

Hi, just a few points: Create a descendant of TThread, override the Execute() method. In Execute() populate the database. Make sure that you check the threads Terminated variable regularly such that the thread can be stopped from outside if needed. If Terminated==true close all open resources (files, database etc.) and leave Execute(). You probably want to show some progress status. Don't show a form inside the thread! Instead create a form in the main thread and define f.e. custom messages that the thread can post to the main thread via PostMessage() such that the main thread will display the status form. Catch exceptions inside your threads Execute(). hope this helps, Nick "Daryl" <stockd (AT) tpg (DOT) com.au> schrieb im Newsbeitrag news:3fdb74db (AT) newsgroups (DOT) borland.com...
