I m sure you are ready to breathe life into your web service to see your hard work in action. Building a web service is like building any other project with the VS IDE. As you know, you can click the small, green Play button in the main toolbox or press F5 on the keyboard to start the application in run-time mode.

This chapter provided more detail on the specific functions of the game controller and how it interfaces to the iPhone. First, I took a look at a similar iPhone accessory, the Griffin iTrip. The iTrip provides the means for connecting the audio output to a FM receiver. Using the iTrip as an example shows you what you can expect with your own accessory. Using a known, productionlevel accessory provides a fantastic baseline to use when comparing your own product development. While an accessory developer would normally create an accessory as part of a solution to a problem, in this case, for the purposes of education, I took a different approach. The rationale was to look at typical communications that happen between an iPhone and any accessory. In general, you are either going to send information to the accessory from the iPhone or the reverse. Starting with the Pong game concept, the most obvious control needed would be to set the position of the player s paddle. For this, you use a potentiometer whose electrical resistance varies as the position is changed. The processor and firmware within the controller reads the voltage from the center tap of the potientiometer and sends that to the iPhone. Though not strictly needed, you add a second user control in the form of a pushbutton to tell the application to serve the ball. Because this function operates much more infrequently than the paddle position, you use an interrupt routine to service the

Several products on the market allow for vulnerability scanning and security auditing on the Mac. Some of them are freeware, and some of them are not. SAINT, Nessus, and Metasploit are our favorites for this critical piece of the security puzzle. Only Nessus and Metasploit are free products.

When you execute the previous command, ADO.NET returns a SqlDataReader. This reader is a forward-based read-only cursor that moves forward by one record every time you call its Read method. The Read method returns True if it reads a record and False otherwise. Upon a successful read, it will then load an array of values with the index of the array representing the column name so reader["ColumnName"] will contain this record s value for ColumnName. Thus, we can iterate through the returned result set using a while loop, and upon a successful read, retrieve the result set s data by simply accessing the reader as if it were an array. Listing 4-1 contains the complete code to access the addresses for postal code 98011 in the AdventureWorks database.

you ve made by using the following command:

Since the control has a name attribute but not an id attribute, which ASP.NET requires, you also need to add this:

WHERE Title LIKE 'Sales%' selects all rows where the Title column contains a value that starts with the word Sales followed by zero or more characters.

Only one application can occupy a certain port at any given time. When developing production-quality applications, you should always allow the user or system administrator to configure the port numbers in a configuration file, via the registry or using a GUI.
