Page 160 item 2. If you see the code in the book, the code is different than what is in your "Download Code". I trying to lean VB and you are not doing a very good job of teaching! You were doing great until chapter 5. This is the second time is this chapter. Go to page 158 item
2. "Public Sub DisplayCustomer(customer As Customer)". That line should be:
"Public Sub DisplayCustomer( ByVal customer As Customer)". The is no excuse for these errors accept sloppy writing and proofing. And at least you could have reviewed the book after publishing or before publishing and did "errata", like some of the good authors do!!!

Both lines of code are correct. ByVal is the default for a parameter. Parameters are passed by value unless ByRef is specified. You can use either line and they will compile to exactly the same code. Please download VS 2012 versions as you continue through the book instead of using the 2013 version.

How come in you "Beginning Visual Basic 2008" book, the code is almost perfect. But the code in "Beginning Visual Basic 2012. I have to use the download code before the code works?? Especially in chapter 5, ByVal is not
in the book, but in the download code. All the code works great when I change the book code to the download code, in 2013. In fact I am using your 2008 book to check your 2012 book code.
