I have the .mobi version, so there are no page numbers.
It's in the first few pages of the book, though.

"The reference to ?typescript? means that the pages must as least resemble something that came out of a typewriter. A double-spaced manuscript page with a fixed-pitch font has about 250 words, as the description indicates. A book page is more in the region of 400 words, so Microsoft Press obviously wasn?t expecting a very long book.

Charles Petzold. Programming Windows?, Sixth Edition (Kindle Locations 163-165). Microsoft Press: A Division of Microsoft Corporation. "

In the My Setup Paragraph Petzold is referring to a Microsoft Comfort Mouse 300, which doesn't exist. I guess he's referring to the Comfort Mouse 3000.

This is more of a user error than a book error. Beware if you are reading the book via Amazon Kindle and using copy/paste to bring code into Visual Studio.

When I copied "<Image Source =" http://www.charlespetzold.com/pw6/PetzoldJersey.jpg" />" into VS the Kindle copy/paste operation added extra spaces into the XAML code:

< Image Source =" http:// www.charlespetzold.com/ pw6/ PetzoldJersey.jpg" />

This resulted in an error from the compiler: ImageSourceConverter cannot convert from System.String. Since a string is the right variable for the Source parameter the message was a red herring. The offending spaces removed, and it is working fine.

Guess I should be retyping the content rather than relying on copy/paste but hey, I've only got so many keystrokes left in my life. See keysleft.com from Scott Hanselman and friends.

This is also a "Question or request for clarification", but we're given only one option.

First sentence of last paragraph in printed book, page 6:
It begins:

The first namespace declaration with no prefix refers to...

Could this instead read:

The first namespace declaration with no suffix refers to...?

(Change is one word: from "prefix" to "suffix")

Reading these namespaces as I do, each one has a beginning, or prefix. Only the 2nd line (xmlns=...) has a statement with nothing following the colon. Doesn't this mean that it's the first namespace declaration with no suffix?

Bottom of page 24, top of page 25

The class hierarchy table starting at the bottom of page 24 has an alignment problem when it continues on the top of page 25.

The "Grid" term (first line of page 25) seems to be indented 2 levels past "Panel" (last line of page 24).

Similarly, "Control" seems to be indented as a child of "Panel".

Obviously the first 4 lines of page 25 must be exdented.

"MediaElement" is oddly spaced in the sentence "You can also use MediaElement for playing movies". I believe it should be italicised.

You need to add 'using Windows.UI.Xaml;' in order for Example 1-11 to compile. Without this using statement, neither of the right hand enums resolve:

txtblk.HorizontalAlignment = HorizontalAlignment.Center;

I have windows 8 release preview.
I am testing the code related to resources.

All Static resources on the book are not found on the standard blank template.

code like this:
Foreground="{StaticResource rainbowBrush}" FontFamily="{StaticResource fontFamily}" FontSize="{StaticResource fontSize}"


It says resource not found or something like that.

I guess they changed the names on win 8 release preview and the new vs express 2012.

Can you or the author send me an email about this?

"Try inserting the following code after the InitializeComponent call in the SharedBrush.xaml.cs file:"

In the SharedBrush project in the source code, there is no SharedBrush.xaml.cs file. I believe it should be BlankPage.xaml.cs.

Bottom of page 102, top of page 103

Another alignment issue.

Sample code at the top of page 103 continues indented one tab stop from code at the bottom of page 102.

But more serious is that the paragraph immediately afterward, starting "At first this might not seem a whole lot different..." is also indented, compared to a normal paragraph on page 102.

Meanwhile, the snippet that spans pages 103-104 exdents, and the normal paragraph indentation resumes ("A bunch of those GradientStop objects..."

Something screwy is going on with the formatting of the document.

The caption "Project: LineCapsAndJoins..." should (arguably) appear immediately next to its associated code snippet, not split across pages.

normally, when using mouse and keyboard, clicking the right mouse button brings up the app bar. In this case it brings up the textbox context menu (as you'd actually expect). Is there a way to address this, and have a solution which allows the appbar to be accessible for mouse and keyboard users?

2nd code block

isn't it premature to use the 'using' construct on the stream and the dataReader when calling LoadAsync? Won't the OnFileOpenReadCompleted method simply return before having completed the read and load in LoadAsync, and just before it returns end up trying to close the stream and the dataReader before the LoadAsync has really finished with them? Or is this somehow magically taken care of?

(It is maybe the case that with small text files it works OK, as the LoadAsync has already completed before the objects are closed. But large files might be different - in fact, just putting a delay in before the call to dataReader.ReadString causes it to throw an 'already closed' exception)

Penultimate paragraph (but many others)

Paragraph indentation is inconsistent.

Consider page 256. The first paragraph ("XamlCruncher lets you...") is indented. As is the secon ("Here's a view...").

Next you have a graphic. Fine.

But the next paragraph "The editor doesn't include..." is flush left. Is it to be considered a continuation of the previous paragraph? Doesn't seem so; it starts a new thought.

On page 257, 2 out of the 3 paragraphs are flush left.

Other flush-left paragraphs appear on pp 258, 265, 268 * 2 and 271.

Looking at a random page earlier in the document, we find these on pp 57, 58 * 3, 60, 61 and so on.

I checked the paragraph indentation style in Applications = Code + Markup and the problem didn't occur there, since all paragraphs were flush left. Ditto for Programming Microsoft Windows Forms.

FYI...

asyncAction.Completed = OnRunAsyncCompleted : There is no handler of that name mentioned in the code listing, but perhaps it's worth mentioning you need to set at least an empty handler on the Completed property in order to get it to start.

Top of C++ file in chapter five named GradientButton.h

I'm referring to the companion content code, thus the page number.
This refers to the C++ code for Chapter 5, the project called DependencyProperties.
The file GradientButton.h

Here's the description at the top of the file:

//
// Block.xaml.h
// Declaration of the Block class

The "Block class" does not come until later in the chapter.
This file refers to the Gradient Button project.
It should read something like:
//
// GradientButton.h
// Declaration of the GradientButton class
