Example 11-1
Example 11-1. Main mehtod of duplicate file finder |
in the example there is an if statement that looks like this
if (args.Length > 1)
{
later nested in the if statement is another if like the following
if (args.Length < 2)
{
Since args.Length is an integer value it should never be possible to be greater than 1, but less than 2.
I'm sure the first statement should have been >= 1

when it should read:

Text doesn't state where the "Point" class comes from - is it from System.Drawing? Should give the appropriate "using" statement.

To make use of the "Point" class in this text you must add the "using System.Windows" namespace, you may also need to add the reference this namespace resides in. To do this in Visual Studio click on Reference in Solution Explorer, choose "Add Reference", click on the .NET tab, and select "WindowsBase" from the list.

Console output is wrong, instead of
Joe is putting out the fire!
Training the hose on the fire.
The fire is going out.
as stated in the book, it really gives

Also, the text seems to assume that nothing has changed ("Unit tests pass"), but the order *has* changed.

"Add the following line" comes *after* the line we're supposed to add. So it should be "Add the above line" or "Add that last line" or something line that, but not "following".

Sample code does not work for me:
1) delegate LogTextProvider has the same name as the corresponding property, compiler flags ambiuity
2) both should probably have the same visibility

Just before example 5-23, you say "When you subscribe to an event your
subscriber implicitly holds a reference to thepublisher.". I think that should
read "the publisher implicitly holds a reference to the subscriber". I find
that to be a very important point as in my experience, this was a common cause
for memory leaks when small objects don't unsubscribe from events in their
dispose(). Not something I see recommended as good practice very often.

console output at bottom |
Once again the output does not match the code!
1) First two lines missing
2) "Tool2 has seen processing, and not canceled." is rather "Tool2 has seen processing, and canceled."
Also, by the way, it should be mentioned that CancelEventArgs requires a "using System.ComponentModel;"

Example 10-65 |
The Console.WriteLine statements read:
Console.WriteLine(builder1.Capacity);
Console.WriteLine(builder1.Length);
Console.WriteLine(builder2.Capacity);
Console.WriteLine(builder1.Length);
The second writeline statement in the second group references the first builder object when it should be the second. It should read:
Console.WriteLine(builder1.Capacity);
Console.WriteLine(builder1.Length);
Console.WriteLine(builder2.Capacity);
Console.WriteLine(builder2.Length);

Examples 10-75 and 10-76 |
The output of these two examples does not describe the removal of the "blank lines" very well. The second example removes lines that have a null as well as the "" and String.Empty of the first example but with the way the lines break from the text to the output of the examples and with the unfortunate way that the output of Example 10-75 spans two pages, the removal of the blank lines is confusing.
Example 10-75 has one line of space between the output and the text as follows.
If we build and run, the output to the console looks like this:
To be, or not to be--that is the question:
So this example removes 8 blank lines but not the null. So assuming the initial blank line is to separate the text from the output, should there be a second blank line.
The output of Example 10-76 removes the null and the debug output reports 9 lines removed but now it has two blank lines separating the text from the output as below.
been ignored:
To be, or not to be--that is the question:
Seems backward and again the placement of the page break does not help.

In this sample output, "nobler" should be "nobelr", because the sample code does not include the replace operation.

First full sentence at the top of the page |
The book makes the following statement regarding installing and setting up SQL Server 2008 Express; "Since that could well happen again between us finishing the book and you reading it, we're providing the instructions as part of the sample code you can download for this book from the O'Reilly website so that we can update them when necessary."
I couldn't find this instruction information anywhere on the O'Reilly website. I looked in the sample code files, the errata area and the main web page for the book and did not find any information on installing and setting up SQL Server 2008 Express. Where is this information located?
