I've been saying that you should never catch an exception if you don't know how to handle that specific exception. There is one case when that rule doesn't apply, and that's the base exception handler for your program -- the last possible place your program could catch the exception before it would crash the program. At that point, all your program can really do is log the error, show a message to the users so they know what's going on, and then close the program. It doesn't really matter what the exact type of the exception was since you're going to handle them all the same way. I'm perfectly willing to let a program crash if an exception occurs. I will have already caught and handled all the exceptions I know about, so anything that manages to reach the very bottom of the call stack is necessarily something that I don't know how to recover from. It is unwise to allow the program to continue running since I have no idea what went wrong. It might have been something trivial, but it might be something very important, too. If it were something trivial, then it probably shouldn't have warranted an exception in the first place. When something goes wrong in the program, I'll definitely want to hear about it. I'd rather not have the user try to dictate the results to me over the phone, of course, so I use something similar to what Delphi 2005 provides. I have a dialog box that shows a stack trace, plus some other pertinent information. It appears in a text box, so the information can be copied and pasted into an e-mail message. Somebody else mentioned MadExcept. It's a great tool. I'd use it, but I can't really justify the price right now, and JclDebug provides similar functionality with none of the cost. -- Rob ----------------------------------------------------- Home page: http://groups.yahoo.com/group/delphi-en/ To unsubscribe: [EMAIL PROTECTED] Yahoo!
