your own code to take this approach. The second alternative is to use XSLT via a web publishing framework like Apache Cocoon. This approach allows you to avoid custom coding of the XSLT extensions to your presentation layer and offers some potential performance benefits from caching algorithms and other means. XSLT is much slower than using compiled templates, but can be a reasonable alternative for large, complicated interfaces that have advanced requirements such as multilocale and/or multidevice support. If you decide that a hybrid J2EE/XML approach is not right for your application, you should investigate other pure J2EE presentation frameworks to give your user interface development efforts a jump start. Two such popular frameworks are Struts and Velocity. Information on both can be found at http://jakarta.apache.org. This chapter concludes our detailed discussion of using XML at each layer of your n-tier J2EE application. The next and final chapter summarizes the concepts and technologies from the first five chapters in the context of a cohesive case study. winforms barcode reader Distinguishing keyboard input from BarCode Scanner input - MSDN ...

I am trying to follow along with the article: Distinguishing Barcode Scanners from the Keyboard in WinForms . However I have the following ... SQL Server does not support a true sense of nested transactions, nor does it support the concept of autonomous transactions yet . When you issue a ROLLBACK TRAN command within a transaction, SQL Server rolls back all activity performed as of the outermost BEGIN TRAN . If you issue a BEGIN TRAN statement within an existing transaction, you don t really open a new transaction . Rather, SQL Server simply increments an internal counter that you can query via the @@TRANCOUNT function . A COMMIT TRAN statement decrements the counter by one, and only the outermost COMMIT TRAN, which decrements the counter to zero, really commits the transaction . SQL Server will limit the number of levels you can open with BEGIN TRAN statements to 32 . SQL Server supports savepoints, which allow you to undo some partial activity within a transaction . To do so, you need to mark a savepoint by issuing a SAVE TRAN <savepoint name> statement and later issue a ROLLBACK TRAN <savepoint name> to undo the activity that was performed as of that savepoint . As an example, remember that in the previous chapter I demonstrated how you can maintain your own custom sequence (autonumbering mechanism) . I demonstrated a solution that maintains a blocking sequence . That is, when a transaction modifies the sequence value to increment it, it acquires an exclusive lock and keeps it until the transaction terminates . Other transactions attempting to increment the sequence value will be blocked in other words, the blocking sequence queues requests for new sequence values . That s exactly what you want to establish in cases where you want to prevent gaps in the sequence for example, when you use the sequence to generate invoice IDs . winforms barcode reader How to distinguish between multiple input devices in C - Code Answer

The task in the second exercise is to query the Orders table, and return for each customer the orders with the most recent order date for the customer .

Our goal has been to cover each component with sufficient breadth and depth to give you a solid understanding. Each individual component, however, is extremely complex and requires its own book for an exhaustive discussion. The goal of this chapter is to provide cohesion to our discussion and the topics that were previously explored. We use a case study to examine an end-to-end architecture that highlights J2EE and XML design patterns and technologies. Throughout this chapter, we produce an application and step through its implementation. All of the materials necessary to run the application can be found at http:/ /www.manning.com/gabrick/. 11025 11046 10739 10850 10994 10822 ... 2008-04-15 2008-04-23 2007-11-12 2008-01-23 2008-04-02 2008-01-08 00:00:00.000 00:00:00.000 00:00:00.000 00:00:00.000 00:00:00.000 00:00:00.000 87 86 85 84 83 82 6 8 3 1 2 6 There are many ways to solve this problem, some of which I ll present here .
