5.Basiclly, it's hard to debug the custom web part(if it's developed by a class libraty instead of web controls). there are some simple tips for debugging the web part. if there is a win2003 server with VS 2005/2003 and sql server integrated, you are lucky. mostly,there is a virtual server for development and test use only. a small tip, compile your assembly into the virtual server directly, so you do not need copy/paste them every time which take your long time. another small thing, if you have try...catch...end try for exception handler(you would better have it !) , it's better to have a small label control added in the catch cluse, so you could get the exception message shown.
