20.4 Summary

At its highest level, you interact with the Application Kit through Interface Builder. In this mode, you use Interface Builder to draw your user interface, and you write handler routines in Project Builder that respond to user actions. You can interact with the Application Kit and classes on a more detailed level by dealing with the framework more directly and writing code to handle more advanced user interactions with your application s user interface. For example, you might write code to handle copying and pasting text or drawing lines or shapes in an application window. The lowest level of interaction involves deriving new classes based on parent Application Kit classes. At this level, you are specializing classes to add functionality to existing framework classes.

As you can see, the XQuery path expression follows the hierarchical structure of the XML document. The first step of the path expression starts at the root of the XML document and then looks below to the <definitions> element. The second step uses a numeric predicate [2], indicating that the second occurrence of the <concept> element should be selected. Finally, the last step of the path expression indicates that the <name> element under the <concept> element should be retrieved. The .value() method accepts both a path expression and a SQL Server data type. It returns a single scalar value from the XML data, cast to the appropriate data type. The SELECT query in listing 5 uses the .value() method on Figure 4 Single scalar the xml data type variable defined in listing 4. The result value returned by the .value() method is shown in figure 4.

Launch Project Builder, select File Create New Project, and select one of the AppleScript Studio project templates. Open the Resource folder using the discloser triangle and double-click on the project s MainMenu.nib file to open the file in Interface Builder. Construct your application s user interface and name each interface component you wish to access from your scripts (more on this later). Create new script-based handlers for interface actions. The development environment creates these handlers and adds them to the main AppleScript of the application. Move back to Project Builder and fill in each handler with AppleScript code that responds to interface actions.

Doubtless, some of you are thinking, Andy, you nincompoop, no one cut and pasted production data ever. Oh really I d wager that in some department in every Global 1000 company, someone somewhere regularly cuts and pastes data into an Excel spreadsheet even now. Read on to discover two ways to perform incremental loads in SQL Server the right way using T-SQL and SQL Server Integration Services.

removeFileCast() (defined in filecaster.js) to remove the file-base by setting the removeFile parameter on the removeForm form 2% and submitting that form. That brings us to the end of the JSP that defines the FileCaster web UI. Now, let s move on to the JSP for the RSS newsfeed.
