16th line from top: The return statement in the ConvertBack method should be:

return (double)(byte)value;

This particular method is not used in the sample program.

First code snippet should be:

lstbox.SelectedIndex = 5;

The ListSortedSystemParameters program does not right justify the contents of the second column. Ed Ball suggests adding the following code at the end of the constructor:

Style style = new Style(typeof(ListViewItem));
style.Setters.Add(new Setter(ListViewItem.HorizontalContentAlignmentProperty,
    HorizontalAlignment.Stretch));
lstvue.ItemContainerStyle = style;

However, I don't discuss styles until Chapter 24, and never the ItemContainerStyle (although it's evident I probably should). Another fix is to insert the following two statements in the definition of factoryTextBlock (on page 365):

factoryTextBlock.SetValue(TextBlock.WidthProperty, 1000.0);
factoryTextBlock.SetValue(TextBlock.TextAlignmentProperty,
    TextAlignment.Right);

The second argument in the first SetValue is just a number larger than the likely actual width the user will set the column to.

Bottom line of code should be:

return (obj as Type).Name;

In the Key.End case of ColorGrid.cs, the statement

x = xNum + 1;

should be:

x = xNum - 1;

Last code snippet, second line should be:

bind.Converter = new MyConverter();

Similarly, the reference in the preceding sentence to "the Convert property" should be "the Converter property".

Second code snippet should be:

"{Binding ... Converter={StaticResource conv}, ... }"

The StylesWithSameKeys.xaml file works fine, but it doesn't agree with the text, and uses an attribute that's not discussed for 3 more pages. To make the file be what it should be, change 2 occurrences of

<Style TargetType="{x:Type Button}">

to:

<Style x:Key="normal">

Change 3 occurences of

<Button>

to:

<Button Style={StaticResource normal}">

In the code listing, the two statements

argsEvent.RoutedEvent = MedievalButton.PreviewKnockEvent;

and

argsEvent.RoutedEvent = MedievalButton.KnockEvent;

should be swapped.

Item Number 2: The WPF extensions for Visual Studio 2005 do not include an empty project option. To add this option, copy this WpfEmptyProject.zip file to the directory:

\My Documents\Visual Studio 2005\Templates\ProjectTemplates\Visual C#

In the New Project dialog, select Visual C# at the left and then WPF Empty Project.

To avoid duplicated entries, the Populate method in DirectoryTreeViewItem.cs should begin with the following statement:

Items.Clear();

Introduction, page x. The URL listed in the "System Requirements" section is no longer valid. The portal to .NET 3.0 downloads is currently:

http://msdn2.microsoft.com/en-us/windowsvista/aa904955.aspx

From there you can go to the page to download and/or install the .NET Framework Redistributable Package (also known as the Runtime Components):

The Runtime Components are not needed if you're running Microsoft Vista. You'll also need the SDK, which you can download as a burnable ISO image:

Finally, you'll also want the extensions to Visual Studio 2005 to support Windows Presentation Foundation programming:
