line of code with a Text Box object

Chapter 5 has the following line of code with a Text Box object
misnamed:

"sw.WriteLine(this.txtMessage.Text);"

Should be:

"sw.WriteLine(this.tbMessage.Text;:"

3rd paragraph, item number 1

"txtURL" is really tbURL, compare this with the table on page 57.

figure 6-7

About box version information shown on page 101 is not consistent with actual about box in running program. Source for this inconsistency is a bug (minor) in AboutBox.cs in the source code as delivered.

AboutBox.cs
was:
this.labelVersion.Text = String.Format("Version {0} {0}", AssemblyVersion);

now (corrected):
this.labelVersion.Text = String.Format("Version {0}", AssemblyVersion);

Iten number 7

"right-click the globe.ico file in your Windows Form browser project..." is misleading, because the language seems to refer to the browser code (Windows Form browser project) loaded in solution explorer. The copy operation described will not work this way. It's really referring to the globe.ico file in the downloaded code sample package on the user's hard drive, which will allow the copy operation to work.

item number 6

Code will only work if the "using System.Windows.Controls" is commented out or deleted, because the code is referenced by "System.Windows.Forms" and "System.Windows.Controls", creating a compiling error. Page 128, item number 4, says to add "System.Windows.Forms" and "Windows.Forms.Integration" to the Browser.xaml.cs code, which resulted in a compile error when the code in item number 6 was added.

Step 6: Bottom of page.

From Chapter 6, Step 6:

private void NavigateToUrl(string Url)
{
WindowsFormsHost host = new WindowsFormsHost();
WebBrowser browserControl = new WebBrowser();

host.Child = browserControl;
this.grid1.Children.Add(host);
browserControl.ScrollBarsEnabled = true;
browserControl.Navigate(Url);
}

Error messages:
Error 1 'WebBrowser' is an ambiguous reference between 'System.Windows.Controls.WebBrowser' and 'System.Windows.Forms.WebBrowser H:\C#Programs\Chap6\MyOwnWpfBrowser\MyOwnWpfBrowser\MyOwnWpfBrowser\Browser.xaml.cs

Error 3 Cannot implicitly convert type 'System.Windows.Controls.WebBrowser' to 'System.Windows.Forms.Control' H:\C#Programs\Chap6\MyOwnWpfBrowser\MyOwnWpfBrowser\MyOwnWpfBrowser\Browser.xaml.cs

item number7, in the CancelButton_Click code.

Because code in C# is case-sensitive, the name "CancelButton_Click" should be "cancelButton_Click" (lower case "c"). Compare with XAML code on page 127, where "Click='cancelButton_Click'" is located near the end.

figure 7-3

The TestApplication.cs code in the DebuggingStart project, as delivered in the code sample, doesn't match the code in figure 7-3 on page 136. This is already a confirmed errata in the list submitted May 6, 2010, but this can still be remedied by the user if the code is changed to exactly match figure 7-3 (page 136), and rest of chapter 7 should work with no problems. There are only a couple of other things to change elsewhere, and page 145 contains the correct code to correct the errors that was supposed to be in TestApplication.cs code in the first place.

Follow these steps:
1. In TestApplication.cs, replace button1_Click method exactly as shown in figure 7-3, page 136. Place breakpoints where indicated.
2. Place breakpoints where indicated in figure 7-4, page 137.
3. As indicated in figure 7-8, page 142, in the ManipulateStrings method in Library.cs code, change "i = myString.Length - 1;" to say "i = myString.Length;". This introduces one of the bugs that chapter 7 narrative steers you into.
4. In the ReadFile method in Library.cs code, place a breakpoint where the line says "return content;", this is line 41.
5. Item number 5, page 141, "ReadToEnd" in italics should be "ReadFile" in italics.

The entire chapter 7 should run flawlessly after these changes are made. Pay attention to what chapter 7 says and what you're doing. I tested this and see no problem.

the brown caution box on the page margin

Caution box says, "The Edit and Continue feature doesn't work on 64-bit operating systems." It works on my 64-bit machine with 64-bit OS. The reason is because 32-bit programs will run on 64-bit machines on a 64-bit Vista OS. So this caution box may need to be reworded.

The last line in the code is incorrect and will invoke a "NotImplementedException was Unhandled" compile error. In the last line, the code "filterByMake;" should be "filterByMake.ToList();"

Item number 1

Item 1 on the page begins with "Click, Add, New Project, and then..." There is no such "Add" menu item in Visual C# 2008, although there is an icon (not a menu item) below the menu bar that allows "Add New Item". But I don't think that's the intent of the author and it's not the same thing.

Sorry, ignore the two previous entries made about page 215. This one is the corrected entry, I left out one word.

The code in item number 4 mentions "Weather_Tracker". This should be "WeatherTracker" without the underscore.
