Also, the use of try/catch in this way is generally not so great because you could "catch" more than you bargained for. Using the if, you're testing for a very specific condition that you can anticipate and handle. With the catch, you will not only catch the exception you expect, but anything else which you don't expect, which you probably should be letting get thrown up to the caller rather than be caught. In general, when dealing with exceptions, you should catch only that which you expect and can deal with, anything else should be allowed to be thrown up to the caller which may understand the context of the exception better, and so be better equipped to handle it. Obviously in this simple example, there isn't much else that could go wrong to cause an exception to be thrown, but it's something to keep in mind. -- --------------------------------------------------------------------- Chris Jensen [EMAIL PROTECTED] Educational Experience (Australia) Postal Address: PO Box 860, Newcastle NSW 2300 Freecall: 1-800-025 270 International: +61-2-4923 8222 Fax: (02) 4942 1991 International: +61-2-4942 1991 Visit our online Toy store! http://www.toysandmore.com.au/ --------------------------------------------------------------------- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Logware (www.logware.us): a new and convenient web-based time tracking application.
