Last paragraph, fourth line from the bottom |
Minor typo, the sentece should read "It can also be a custom event that you define in
your code.", instead of "In can also be a custom event that you define in your code."
{Chapter 3.4.4} has a few mistakes:
After the exhibit of Class1 and Class1Derived, you declare c1, c2 and
c1Var. you then call the objects incSalary method instead of
showIncSalary (this mistake repeats itself throw the chapter).
At the end of the chapter, you write:
MyClass.IncSalary
Returns 10000
Instead of 11000.

...output in this case is:
Class2 method that overrides
Class1 method that shadows
x = 1
BUT it should be:
Class1 method to shadow
since the sample code on page 80 says so :)

The text describes declaring a delegate: 'Delegate Sub AMethodDelegate(ByVal s As
String)'. A little further down the page it says that you need to instantiate the
delegate, but it leaves the word 'Method' out of the delegate's name: 'delg = New
ADelegate(AddressOf obj.AMethod)'

Last paragraph |
States that the Addhandler statement "makes it possible to bind several event
handlers to a single event". It is, in fact, the other way around - multiple events
are bound to a single handler.
This error is repeated on page 95, third last paragraph.
A small error in an otherwise excellent book.

Example 9-2 |
Example 9-2 creates an Integer and Object array like this :
intArray = New Integer(5) {}
empArray = New Employee(3) {}
The above two statements create an Integer array of 6 elements (since 5 is the
array's upper bound) and Employee object array (after initialization of the array, of
course) of 4 Employee objects and NOT as show in the book example. The book example
shows that the array created is 5 integers and 3 Employee objects and this is wrong !

Example 9-6 |
Example 9-6 shows the creation of a two dimensional array :
'declare a 4X3 Integer array
Dim rectangularArray(rowsUB, columnsUB) As Integer
Since rowsUB is iniatilized to 4 and columns UB is initialized to 3, this creates an
array of 5 rows and 4 columns (5X4 Integer array) and NOT 4X3 as shown in the example
in the book.
Also, in the same example there is no need to do rowsUB - 1 or columnsUB - 1 when
accessing the rows or columns in the array, since rowsUB and columnsUB define the
upper bound of the array.

The format specifiers listed for the Format Function in the language reference have a
serious error in that 'n' is not a valid format specifier, and instead is passed
through as a literal character. 'n' should instead be 'm' (lower-case) which is used
to specify minutes. Months should be specified as 'M' (upper-case) in your format
string.
For example: Format("10/1/2002 11:47 AM", yyyy-mm-dd) will yield "2002-47-01".
Format("4/6/2002 12:15 AM", hh:nn:ss) will yield "12:nn:15".
Furthermore, the documentation for hour values is incomplete, just showing 'h' and
'hh' which are hour values in non-24 hour format (5pm instead of 17:00), without and
with leading zeros. There are two other formats 'H' and 'HH' which format the time
into a 24-hour format.

the last entry |
under "Condition" heading reads " start > len(string2) " to indicate that this would
return 0. This isn't true and is a carry over from the same mistake in Microsoft'
documentation. It should read "start > len(string1)" . To start searching in
string1 past the length of string1 returns 0.
