7 220 2nd line from bottom of page
Should read: Unlike variables, where the Dim statement defines a class, only the Class keyword followed by the class name (in this case, Person) has been used. The keyword, Public means that the class will be available to all other programs. This is necessary, as an ASP.NET page will use it.

Change: This validation checks whether the age is less than zero,
to: This validation checks whether the age is less than one,
10/19/04
7 225 Last line on page
The New keyword specifies that the object is being created, and therefore causes the constructor to be run. Also, because the property is now read only, the line that explicitly sets the eye color has to be removed:

myPerson.EyeColor = "Blue"
10/14/04
7 228 2nd line of step 4
Should be: You'll see a simple display that shows the name of the person and the direction they are traveling in, as shown in Figure 7-4:

8 262 1st sentence in step 3
Should be: Pick the SELECT Data Method and drag it from the Toolbox, dropping it into your code window (make sure that where you drop the toolbox item is outside any existing procedures):
10/14/04
8 272 2nd table, 1st description for method "ExecuteNonQuery"
Should be: This executes the command but doesn't return any rows of data. It is useful for commands that perform an action, such as updating data, but that don't need to return a set of data. A value is returned, indicating the number of rows affected by the command.
10/14/04
8 278 1st paragraph, 2nd sentence after "The DataReader Object" heading
The DataReader, an object that we haven't come across yet, is optimized for reading data.

Last line should be: dataAdapter.Fill(data)

9 285 1st code block
1st code block should be:
dataAdapter.Fill(data, "Products")
dataAdapter.SelectCommand.CommandText = "SELECT * FROM Employees"
dataAdapter.Fill(data, "Employees")

10/14/04
9 285 The following addition goes after the first code block on this page
The problem is that this code doesn't work as expected, because IDbDataAdapter doesn't accept the table name as an argument. For this to work you have to use the actual class, OleDbDataAdapter, rather than the interface:
System.Data.OleDbOleDbDataAdapter dataAdapter =
new System.Data.OleDbOleDbDataAdapter();
dataAdapter.SelectCommand = dbCommand;
System.Data.DataSet data = new System.Data.DataSet();
dataAdapter.Fill(data, "Products");
10/15/04
9 287 Step 4, 2nd sentence
Should be: Also drag two the Label controls onto the page and position them as headings to show the contents of selected items from the Datagrid controls.

9 295 Addition to end of last paragraph & replacement for final code block as follows:
Finally we update the data for the selected row. There could be many rows returned by the Select() method, so we index into the array. In our case we know that there is only one row returned at most one row. We check the Length of the SelectedRows array to make sure that at least one row was found, as trying to update the row would fail if nothing was found.:
// Find the row to change
selectedRows = table.Select("FirstName='Margaret' AND LastName='Peacock'");
if (selectedRows.Length > 0)
{
selectedRows(0).Item("FirstName") = "John";
selectedRows(0).Item("LastName") = "Hartford";
}

// bind the data grid to the new data
DataGrid3.DataSource = table;
DataGrid3.DataBind();

VaryByHeader enables you to cache pages specified by different HTTP headers, using a semicolon-separated list of strings.
Delete the 2nd sentence.
9/17/04
15 576 4th full bullet on the page
Replace current bullet with:
VaryByParam enables you to cache sections of the page according to a list of parameters, which are also supplied as a semi-colon delimited list of strings. These strings will either be a query string , or a parameter sent via the POST() method. The permissible values include none,*, or any valid query string or POST() parameter name. You must include this attribute whenever you output cache an ASP.NET page or user control, because a parser error will result otherwise. To ensure the entire page is cached, just set the value to none. The "*" (asterisk) setting specifies that the Output Cache should hold a version of the page for every parameter property that your control returns.
