There are several alternatives to this implementation that are worth considering. For very simple data storage needs, you may be able to get by with serializing your data to a plist file using the NSCoder APIs. This has the advantage of being as simple as a call to writeToFile:atomically:. The disadvantage is that the entire data set has to be loaded into memory each time, and there is no built-in way to search through the objects and bring back just the necessary set. This isn t recommended for storing more than a handful of records. If your application has higher data demands, there are other higher-end alternatives as well. It seems like every time I check, there are a few more floating around to handle this. The two I m familiar with are FMDB and Apple s implementation of an object graph persistence framework: Core Data. FMDB is roughly equivalent to the ISDatabase class, with some code to handle more automatic retries, the option to store prepared statements for a speed boost, and handling for more SQLite error states. It s a solid implementation, and you wouldn t be remiss in using this as the basis for an Active Record variant of your own. Core Data is Apple s persistence framework. It has built-in Xcode support for creating schemas and migrations visually. It is fast, robust, and available as of iPhone SDK 3.0.

NOTE: Do not store the .pem file in a web-readable directory! Now, run the PHP script, and if everything goes according to plan, it should look likeFigure 10-19.

-LogName <string> Specifies the event log. Enter the log name (the value of th e Log property; not the LogDisplayName) of one event log. Wil dcard characters are not permitted.

The UriMapper property of the frame class is read/write. Should you desire, you can create your own UriMapper implementation, using your own scheme for mapping URIs. To do so, inherit from UriMapperBase and provide the required functionality in the MapUri function. In the example at the beginning of this chapter, you saw how the mapper automatically translated /CustomerDetail into /Views/CustomerDetail.xaml. The default UriMapper class exposes the UriMappings collection. Here s the full XAML for the mapping:

Now it is time to use what we ve learned about ADO.NET to implement the data layer of our video poker machine. First, we need to create the application database. If you have SQL Server installed on your local machine, or you have database creation privileges on a server elsewhere, then you can create a new database with the script shown in listing 4.7. Otherwise, you ll have to seek the assistance of your local database administrator.

This basic line of XAML sets the FontSize to a 24 pt font. In addition to setting the FontSize, there are also times where you may need to work with the weight of a font.

Note: Our bound controls required that at least one object be present in the collection. Otherwise, the subsequent lines will throw an exception. A more elegant solution might be to unbind the controls and disable the tab control in this case. 9 Add code to the end of the method to retrieve the CurrencyManager object used to manage the _album data source.

In addition to decoding and encoding characters with String.fromCharCode() and charCodeAt(), you can convert their case to lowercase or uppercase with toLowerCase() or toUpperCase(). For example, fight scenes in Batman comic books would have onomatopoeic words such as pow, bam, and zonk superimposed in uppercase. So in Firebug, let s add some pop to some lowercase onomatopoeic words with the help of toUpperCase(): "Pow! Bam! Zonk!".toUpperCase(); // "POW! BAM! ZONK!" Conversely, if the Penguin were to quietly spray a paralytic gas on Batman and Robin with his umbrella, we might want to tone down "PSST...ZZZZ" with toLowerCase(), verifying both samples with Figure 2 9. Note that toLowerCase() or toUpperCase() only manipulate letters. So, nothing weird like the ! changing to a 1 will happen. "PSST...ZZZZ".toLowerCase(); // "psst...zzzz"
