The abbreviation "IL" isn't defined until page 28.

2nd from last sentence in 2nd paragraph

Please switch "functional" and "a" around. It should look like this:
"...which is a functional subset of the CLR..."

The entire sentence should read:
"Microsoft has submitted the Common Language Infrastructure (CLI), which is a functional subset of the CLR, to ECMA, so a third-party vendor could theoretically implement a CLR for a platform other than Windows."

C# code example at the bottom (hello.cs)

Currently the example (hello.cs) reads like this:

1. using System;
2.
3. class MainApp
4. {
5. public static void Main()
6. {
7. Console.WriteLine("C# Hello, World!");
8. }
9. }

In order for the example on page 23 (which uses the Reflection API to inspect the hello.exe file) to work, line 3 above must be changed to:

public class MainApp

Otherwise this example does not work using .NET Framework SDK Beta 2, which is downloadable from Microsoft.

compiling the code, even with the proposed change from
public class Meta to public class MainApp produces the following error:

as fields or methods

Figure 5-3

There are five tree structures in Figure 5-3 on page 124. The bottom tree structure has a parent box reading, "DBDataAdapter". It should read "DbDataAdapter". (The second character, "B", should be lower-case.)

The example uses HttpPost protocol, so SOAP should be HttpPost.

The example in the paragraph labeled "@Page" (4th paragraph)

The example on page 199 for the "@Page" directive reads:
<@ Page Language="VB" ErrorPage="URL" EnableViewState="true">

Someone forgot to add the percent signs at the beginning and at the end of the directive. It should read like this:
<%@ Page Language="VB" ErrorPage="URL" EnableViewState="true"%>

Following 3rd paragraph in Directives section

Page directive example written as:

<@ Page Language="VB" ErrorPage="URL" EnableViewState="true">

should be written as:

<@ Page Language="VB" ErrorPage="URL" EnableViewState="true" %>

since it is a directive.

Figure 8-1 - top of page - Where is the ControlBox?

In the last paragraph on page 238, the author speaks of turning off the ControlBox. However, as I am reading it, I am having trouble understanding where and what the ControlBox is. It would be helpful if it was specified what the ControlBox is in Figure 8-1 at the top of page 239.

30th line of code

30TH LINE OF CODE IS : arrIterator.Reset() ;

This doesnt work and generate a InvalidOperationException.

I think, Enumerator becomes invalid if anychanges is made to the ArrayList. Since Sort is called before the Reset, enumerator becom
es invalid!

Maybe the code should be written like this,

CODE FROM LINES 22 TO 34

i = 0;
arrIterator = arrList.GetEnumerator();
Console.WriteLine("There are: {0} days in a week.", arrList.Count);
while(arrIterator.MoveNext())
{
Console.WriteLine("[{0}] {1}", i++, arrIterator.Current);
}
arrIterator.Reset();
arrList.Sort();

i = 0;
// Since Sort is called before this line,Enumerator becomes invalid
//and so Reset called earlier is of no use. We have to create a new
//Enumerator to go though the list.

arrIterator = arrList.GetEnumerator();
Console.WriteLine("Sorted as Text");

while(arrIterator.MoveNext())
{
Console.WriteLine("[{0}] {1}", i++, arrIterator.Current);
}

last paragraph

the shrimp in question is blind, not the gobies. Consequently, the shrimp, being nearly
blind, doesn't do much of the hunting; the goby provides food for rent.
