When I originally wrote each of these books, I had at least one technical editor and a number of beta readers checking my code under various conditions to ensure the code would run as advertised on the maximum number of systems. I no longer have the support, so I’m testing these updates on just my systems. If you encounter a problem with the source code of any of these books, please be sure to contact me at John@JohnMuellerBooks.com. Now, here’s the important part. Make absolutely certain to let me know that you’re using a newer browser—one not originally tested in the book so I can handle your query correctly and also provide an update on my blog. Your input will help other readers.
Whenever possible, I encourage readers to use the environment described in the book to write their own code. Doing so reduces the potential for problems because I know that the environment is tested by a number of people in a number of environments. However, sometimes using the original environment isn’t possible any longer, such as this instance where Microsoft is putting its collective foot down and forcing an update. Please be sure to write me if you have any questions about the source code for these book. Thanks, as always, for your continued support!
