Xcode 4 ios: Displaying Notification Messages

This will focus on the different methods in which we can make our applications communicate and grab the user's attention. You may, for instance, want to notify the user that an error has occurred, or that the user will need to wait while information is being retrieved or saved.

In this article by Steven F. Daniel, author of Xcode 4 iOS Development, we will:

• Explore and use the different notification methods
• Learn how to generate alerts to notify the user
• Learn how to go about using action sheets to associate with views
• Handle alerts via sounds and vibrations

wxPython 2.8: Window Layout and Design

In today's world of desktop applications, there is a great amount of incentive to be able to develop applications that can run in more than one environment. Currently, there are a handful of options available for cross-platform frameworks to develop desktop applications in Python. wxPython is one such cross-platform GUI toolkit for the Python programming language. It allows Python programmers to create programs with a complete, highly-functional graphical user interface, simply and easily.

In this article by Cody Precord, author of the book wxPython 2.8 Application Development Cookbook, we will cover:

• Using a BoxSizer
• Understanding proportions, flags, and borders
• Laying out controls with the GridBagSizer
• Standard dialog button layout
• Using XML resources
• Making a custom resource handler
• Using the AuiFrameManager

Writing XML data to the File System with SSIS

This article by Dr. Jayaram Krishnaswamy, shows how you may retrieve XML data from a relational database and write it to a folder on your file system as a text or xml file using Microsoft SQL Server Integration Services 2008. The following are the different steps involved in this EL process (there being no transformation):

• Creating a stored procedure that retrieves XML
• Creating a package in BIDS or Visual Studio 2008
• Adding and configuring a ExecuteSQL task
• Adding and configuring a Script task
• Running the package and verifying the results

Writing a Package in Python

This article by Tarek Ziadé focuses on a repeatable process to write and release Python packages. We will focus on how to install, uninstall, develop, test, register, and upload a package.

Working with XML in Flex 3 and Java-part2

In the first part of this article series by Satish Kore, we started with the basics of XML and move ahead to understand E4X completely. In this article, we will learn about loading external XML documents and also implement the concepts through an example— Building a book explorer.

Working with XML Documents in PHP jQuery

In this article, by Vijay Joshi, author of PHP jQuery Cookbook, we will cover:

• Loading XML from files and strings using SimpleXML
• Accessing elements and attributes using SimpleXML
• Searching elements using XPath
• Reading an XML using DOM extension
• Creating an XML using DOM extension
• Modifying an XML using DOM extension
• Parsing XML with jQuery

Working with User Defined Values in SAP Business One

The User-Defined Values function enables SAP Business One users to enter values, originated by a predefined search process, for any field in the system (including user-defined fields). This function enables the user to enter data more efficiently and – perhaps most importantly – more accurately. In fact, the concept is sort of a "Workflow Light" implementation. It can both save user time and reduce data double entries.

In this article by Gordon Du, author of Mastering SQL Queries for SAP Business One, we will see how to work with User-Defined Values.

Working with the Report Builder in Microsoft SQL Server 2008: Part 1

Report Builder 2.0 is feature-rich reporting tool with the latest Microsoft Office look and feel. In this two part article by Jayaram Krishnaswamy, we will see how the Report Builder 2.0 provides an extremely flexible GUI with user friendly wizards for creating the Tablix data regions, a versatile construct that includes tables, matrix, and charts and gauges. Report Builder 2.0 supports server resources such as shared Data Sources, works with SQL Server Data Sources and many third party products, and can directly open and edit server hosted reports. Report Builder together with Report Manager provides powerful support for building and managing a bewildering array of report types.

Working with Simple Associations using CakePHP

Database relationship is hard to maintain even for a mid-sized PHP/MySQL application, particularly, when multiple levels of relationships are involved because complicated SQL queries are needed. CakePHP offers a simple yet powerful feature called 'object relational mapping' or ORM to handle database relationships with ease.In CakePHP, relations between the database tables are defined through association—a way to represent the database table relationship inside CakePHP. Once the associations are defined in models according to the table relationships, we are ready to use its wonderful functionalities. Using CakePHP's ORM, we can save, retrieve, and delete related data into and from different database tables with simplicity, in a better way—no need to write complex SQL queries with multiple JOINs anymore!
In this article by Ahsanul Bari and Anupom Syam, we will have a deep look at various types of associations and their uses. In particular, the purpose of this article is to learn:

• How to figure out association types from database table relations
• How to define different types of associations in CakePHP models
• How to utilize the association for fetching related model data
• How to relate associated data while saving
