Page 15

Installing Visual Studio.NET. Be aware that your local Web server must be installed before you install VS.

Page 19

This minor fix applies throughout the book. When creating a new web service or other web application the book tells you to enter the application name in the Name box on the New Project page (figure 1.4). Visual Studio net has changed so that you must enter the name in the Location box. The name must be typed after the Web server URL, so that for a program called "First Service" the Location box should read "http://localhost/FirstService"

Page 43

The second line of code on the page reads:

Dim strPhoneNumber As Strong = Request.Form("Phone")

The data type should be "String" and not "Strong."

Page 44

Listing 2.7 requires these corrections:

Line 8: change "nKeyIndex" to "nKeyIdx"
Line 10: delete the semicolon
Lines 11 & 12: change as follows:

Response.Write( "<tr><td>" & Vars.GetKey(nKeyIdx) & "</td>")
Response.Write( "<td>" & Vars(nKeyIdx) & "</td></tr>" )

Page 45

In Listing 2.9 there is a stray semicolon at the end of the 4th line - delete it.

Page 56

In the analysis section, two lines of code end with a semicolon - the semicolons should be deleted.

Page 67

At the end of Listing 3.10 there is a comment detailing how to compile the class. It mistakenly uses "myclass.cs" when it should use "myclass.vb".

Page 68

The first line of code should be moved down so it comes after the Imports statements:

Imports System
Imports System.Web
Imports System.Web.SessionState

Namespace MyApplication

Also, the note on how to compile at the end of this listing specifies "globalclass.cs" when it should say "globalclass.vb". In addition the command line used to compile this listing must also include a reference to the system.web.dll file:

vbc /out:bin\globalclass.dll /t:library /r:system.dll /r:system.web.dll globalclass.vb

Page 141

Listing 6.7, line 28 should read:

Dim tsDaysLeft as Timespan = dtChristmas.Subtract(dtSelected)

Page 235

A reader pointed out that Listing 10.1 will not display table cells correctly for cells that happen to contain an empty string. He suggested the following fix. Add the following declaration at the start of the code (just before line 9):

Dim str as string

Then replace line 23 with the following 3 lines:

str = r(i).ToString()
if str = "" then str = "&nbsp"
Response.Write("<td>" + str + "</td>")

When you unpack the ZIP you will have a folder for each of the book's chapters that contains listings, and a file in each folder for each of the numbered listings. If the listing is given a specific name in the book it will have that same name in the download. Otherwise it will be named as per the listing, for example List0502.txt. You can then copy and paste code from the listings into your Visual Studio projects. Note that any code corrections listed on this page will also have been made in the download listings.
