bottom paragraph |
While beginning to introduce the differences between previous versions of VB and
VB.NET, the author claims code migration from the former to the latter is explained
in Appendix A of the text. However, Appendix A deals with custom attributes defined
in the System namespace - an entirely unrelated topic. Since the topic is also
missing from the other appendices, it would seem to be a reference to a section of
the book not included in the final release.

Dynamically allocating arrays - 2nd Code Example |
Problem:
An example showing syntax for creating an uninitialized array has a comment which
reads
'allocates an uninitialized array of five Integers
but the code shows
a = New Integer(5) {}
The comment should indicate that this statement creates an array of six (not five)
integers.

First full paragraph |
The 3rd sentence states "When Option Strict is On, attempts to perform an implicit
widening conversion result in a compiler error."
It should instead read:
"When Option Strict is On, attempts to perform an implicit narrowing conversion
result in a compiler error."

Paragraph 1 |
This is mainly a problem of (IMHO) very unclear wording, but...
Page 44-45 states
"Visual Basic .NET divides the operators into groups and defines each group's
precedence relative to the others. Operators in higher-precedence groups are
evaluated before operators in lower-precedence groups. Operators within each group
have the same precedence relative to each other. When an expression contains
multiple operators from a single group, those operators are evaluated from left to
right."
The VB.NET documentation, at
http://msdn.microsoft.com/library/default.asp?url=/library/en-
us/vblr7/html/vagrpOperatorPrecedence.asp
states something more in-line with other languages, that is seemingly different from
your book.
In truth, it isn't different and the book is correct. The groups you're talking
about are listed in a table on p. 45. The problem is that the table doesn't make it
clear that the groups of operators are the "Operator" column in the table, not the
"Category" column. This caused me to say "huh?!?!" and reread the section several
times before I realized what you meant.

Comment beginnin "This forces all derived classes..." |
The comment reads: "...Notice that a method marked with MustInherit has no body in
the base class."
Should be: "...Notice that a method marked with MustOverride has no body in the base
class."

4th bullet point - "Constructors aren't inherited..." |
This section refers to the Ellipse and Rectangle class definitions.
There is no Ellipse and/or Rectangle objects defined in the code snippet that this
bullet point is referring to.

Paragraph beginning "Observe that even though..." |
The paragraph states:
"Observe that even though the variable y is passed by value to the TestByVal
method"...
However, the code in the book has "y" being passed to the "TestByRef" method.

The text claims attributes are discussed earlier in the chapter, while they are
actually discussed later, starting on p. 105.

Paragraph begining "Calling the ShowDialog" |
"The call is asynchronous, meaning that code following the call to the ShowDialog
method isn't executed until the dialog box is dismissed."
This is actually synchronous execution. Asynchronous would mean that code following
the call would continue to be executed.
