Note that if the default username and password aren t correct for your system, you can use the -u and -p options to change them if you had username fred and password john, you could do the following as the initial command: mysql -u fred -p john. The remainder of the commands would be the same. At this point, you should have a working MySQL database with a few tables in it. You can then test the script using the following command: ruby mysql2html.rb -d mysql2html_test -t test

Our handler now branches. If the two fields we re looking at are empty, we show a message and stop; if not, we submit the form via Ajax. Either way, we want to stop the default action of the form, so we move the event.preventDefault call to the top of the function (see Figure 5-8).

Dim numResults As Integer = CInt(testCommand.ExecuteScalar()) 1. Add a call to the ExecuteScalar method to the code created in Example 5.1 so far. 2. Make sure you open the connection object before you execute the ExecuteScalar method, and close it afterwards. 3. Output the result of the ExecuteScalar method to the console, making the final code look like Listing 5-3 or 5-4. Listing 5-3. Executing a Simple Command in C# string connectionString = "Data Source=(local);Initial Catalog=Test;Integrated Security=SSPI;" using (SqlConnection testConnection = new SqlConnection(connectionString)) { SqlCommand testCommand = new SqlCommand("SELECT COUNT(*) FROM TestDemo",testConnection); testConnection.Open(); int numResults = (int) testCommand.ExecuteScalar(); Console.WriteLine("Total number of rows in TestDemo: " + numResults); testConnection.Close(); } Console.Read();

This works just like we expected. But let s try something a bit subtler. Imagine that each of the text boxes has a state that s either valid or invalid. At any point in time, it s either one or the other. Both text boxes need to be valid before the form is submitted. Let s write a CSS rule for an invalid text box:

Modifying existing rows is easy. You just find the right row and the right column and assign it a value. This is shown in the code snippet here:

<html> <head> <title>MySQL Dump of Users</title> </head> <body> <h1>Users<h1> <table> <tr> <th>Logon</th> <th>Password/th> <th>Joined</th>

rowInQuestion = animalsTable.Rows[0]; rowInQuestion["AnimalName"] = "Dog";

input#food_type.invalid, input#taste.invalid { border: 2px solid #900; }

rowInQuestion = animalsTable.Rows(0) rowInQuestion("AnimalName") = "Dog" The DataRowState at the end of this edit would be Modified. By now you might already know this, but I must reiterate, modifying a row as shown in an in-memory disconnected cache does not mean that the underlying database got modified too. The database does not get modified unless you successfully call an Update on the relevant data adapter. There is another way of modifying rows. The DataRow object has a method called BeginEdit, and a matching method called EndEdit. You can modify the rows between these two method calls. The difference here is that all the changes are buffered until you call EndEdit. If, in case you change your mind, you call CancelEdit instead, all the changes are rolled back. This can be seen in the following code snippet:

So that we aren t too subtle, an invalid text box will be shown with a thick red border. When the page loads, both text boxes are empty, but neither one can be called invalid yet, because the user hasn t had a chance to enter text. But we know it s definitely invalid if the text box receives focus, then loses focus, and is still empty. That s when we should alert the user. There s an event for losing focus it s called blur. So let s use it.

rowInQuestion = animalsTable.Rows[0]; rowInQuestion.BeginEdit(); rowInQuestion["AnimalName"] = "Dog"; rowInQuestion.EndEdit() ; // This could have been rowInQuestion.CancelEdit() also

</tr> <tr> <td>Mister X</td> <td>eagle//beagle/3</td> <td>Mon Oct 09 14:56:58 Eastern Daylight Time 2006</td> </tr> <tr> <td>Star Captain Y</td> <td>tender++camel</td> <td>Mon Oct 09 14:57:01 Eastern Daylight Time 2006</td> </tr> <tr> <td>Doctor Z</td> <td>beable+proge-3</td> <td>Mon Oct 09 14:57:04 Eastern Daylight Time 2006</td> </tr> </table> </body> </html> As you can see, our script and template will produce nicely formatted HTML output from a MySQL database; let s take a look at how it works behind the scenes.
