The unconfirmed error reports are from readers.  They have not yet been 
approved or disproved by the author or editor and represent solely the

Here's a key to the markup:
        [page-number]: serious technical mistake
        {page-number}: minor technical mistake
        <page-number>: important language/formatting problem
        (page-number): language change or minor formatting problem
        ?page-number?: reader question or request for clarification

UNCONFIRMED  errors and comments from readers: 


(12) List number '3.' and '4.';
I believe that the sentences that start with "In the Code View of Default.aspx", the 
"Default.aspx" should be "Default.aspx.vb" for #3, and "Default.aspx.cs" for #4.

Either that, or perhaps it could specify the code-behind page?


{15} Step 5. Lines 4 & 5 of code sample;
From printed June 2005 First Edition.

Sample code shows:
Handles rblMaritialStatus.SelectedIndexChanged
If rblMaritialStatus.SelectedValue = "Single" then
txtAge.Focus()

Should be:
Handles rblMaritalStatus.SelectedIndexChanged
If rblMaritalStatus.SelectedValue = "Single" then
txtAge.Focus()

Spelling error = rblMaritialStatus


[27]  First sentence;
There is no code given for btnPostback button click on the default2.aspx page;
therefore when you click the button, an "Object reference not set to an instance of
an object." error is displayed.


(46) Tip;
Can't find downloadable images as promised at this url: http://www.oreilly.com/cataqlog/aspnetadn


{71}  Code sample in Example 2-4;
The section of the code sample that describes how to use an image control for the
path-separator character in the SiteMapPath control is incorrect. The example code
encloses the asp:Image control in an <ItemTemplate> tag (inside the
<PathSeparatorTemplate> tag) -- this is not correct. The correct code should simply
enclose the asp:Image control directly inside the <PathSeparatorTemplate> tag.


(86) Example 2.8;
Would be helpful to add:
Imports System.IO
to top of code behind file


{242}  1st paragraph;
Many of the pages refer to the Form_Load event instead of the Page_load event.  This
is a minor mistake, but I thought that I would point it out.
