What is the WordPress loop? The loop is a group of PHP instructions that retrieve posts from the database of your WordPress site and then displays them on the page. You can find the WordPress loop inside your themes, for example, inside index.php, single.php, or page. php. Any HTML or PHP code placed between the beginning of the loop and the end will be used for each post.
In this article by Ric Shreves, author of WordPress 3 Cookbook, we will cover:
- How to work with the WordPress loop
- How you can retrieve posts from a specific category
- How to control how many posts you display
- Retrieving posts by date
- Showing only those posts published today
- How to show posts published exactly one year ago
- How to set up and use multiple loops
The BuddyPress (BP) Courseware plugin by ScholarPress transforms our WordPres site into a learning management system. This plugin provides educators with the ability to post and organize course content, assignments, bibliographies, and schedules. BP Courseware works by extending the BuddyPress group functionality. Each courseware-enabled group receives a courseware dashboard where teachers and students can quickly access and post course content. The BP Courseware plugin is ideal for managing multiple courses by the same instructor or for an entire academic department.
In this article by Adam D. Scott, author of the book WordPress for Education, we'll cover techniques to install and configure the BP Courseware plugin. Once the plugin is installed, we'll develop content for a sample courseware course by adding course information, posting assignments, grading student assignments, creating a bibliography, and managing the course calendar.Read Wordpress: Buddypress Courseware in full

In this article by Brian Bondari and Everett Griffiths, authors of WordPress 3 Plugin Development Essentials, we will learn about a special type of WordPress plugin: the widget. The architecture of widgets has undergone a radical change starting with the release of WordPress 2.8, so now we must talk about Object Oriented programming. We will learn a bit about its power as we extend the WP_Widget class to create our widget. We will also learn how to create a preference page in the manager so we can store our plugin's configuration details.Read WordPress 3: Building a Widget in full
It stands to reason that we can't properly secure a WordPress site until we have a heads-up on its vulnerabilities and the threats it faces. So let's kick off by ensuring awareness.
In this article by Olly Connelly, author of WordPress 3.0 Ultimate Security, we'll set the scene by introducing the hackers and their tricks and considering how the former plies the latter against a site, whether directly or indirectly:
- Knowing the enemy, the variety of mindset, and the levels of skill
- Considering physical security and the threat from social engineering
- Weighing up OS security, allow vs. deny policies and open vs. closed source
- Mulling over malware in its many shapes and forms
- Assessing risks from local devices such as PCs and routers
- Treading carefully in the malicious minefield that is the web
Many local and online risks double up to threaten sites and servers as well, and in some cases the opposite is true. With our web assets though, given their constant availability and valuable prizes for the successful assailant, malicious possibilities, and the temptation to exploit those rocket our subject’s risk factor, off the chart, to a sky-high level.
In this article by Olly Connelly, author of WordPress 3.0 Ultimate Security, we will cover:
- Sizing up vulnerabilities to WordPress and its third party code
- Addressing the frailties of and attacks to your server-side environment
Most likely, today, some hacker tried to crack your WordPress site, its data and content. Maybe that was just a one-off from some bored kid. Just as likely, it was an automated hit, trying dozens of attacks to find a soft spot. Then again, quite likely it was both. What we must do is to solidify your WordPress and other logins so you can securely administrate while keeping your data and credentials flying well under the radar. We'll put the best web protocols to work, along with added defenses, chiefly from Apache.
In this article by Olly Connelly, author of WordPress 3.0 Ultimate Security, we will cover:
- IP deny with mod_access
- Password protect directories
- Authentication with mod_auth
- Better passwords with mod_auth_digest
- More authentication methods

This article by Jayaram Krishnaswamy introduces the reader accustomed to working with the traditional graphic user interface in earlier versions of VB to Windows Presentation Foundation. Importantly, it introduces the reader to the XAML's declarative format and what it means in the design interface of VS 2008. WPF can do a great deal more than what is described in this article. The power of markup extensions such as declarative binding, dynamic resource, template binding and many others are not discussed. It is hoped that the reader will be up and running WPF projects based on his previous experience after reading this article.Read Windows Presentation Foundation Project - Basics of Working in full

The development environment of choice in this article by Stefan Björnander is the Visual Studio from Microsoft. In this article we also study the Microsoft Foundation Classes (MFC).
- Visual Studio provides us with a few Wizards—tools that help us generate code. The Application Wizard creates an application framework (a skeleton application) to which we add the specific logic and behavior of our application.
- When developing a Windows application, the Document/View model comes in handy. The application is divided into a document object that holds the data and performs the logic, and one or more views that take care of user input and display information on the screen.
- When an event occurs (the user clicks the mouse, the window is resized) a message is sent to the application, it is caught by a view object and is passed on to the document object. There are hundreds of messages in the Windows system. However, we only catch those that interest us.
- The device context can be viewed both as a canvas to paint on and as a toolbox holding pens and brushes.
- When we finish an application, we may want it to occur in the same state when we launch it the next time. This can be archived by storing vital values in the registry.
- Serialization is an elegant way of storing and loading values to and from a file. The framework takes care of naming, opening, and closing the file, all we have to do is to fill in the unique values of the application.
- The cursor has different appearances on different occasions. There are several predefined cursors we can use.
Windows Azure Service Bus offers features that are not offered by any other cloud platform on the market. One important feature is the Service Bus that enables you to connect your on-premise services to Windows Azure services and beyond. The Access Control Service enables you to easily authenticate users without having to write complex authentication code ourselves. By using Windows Identity Framework (WIF) and supporting identity providers such as Live ID, Yahoo, and Facebook, it will be easy to use these identity providers as the main authentication mechanism in our own services.
In this article by Riccardo Becker, author of Windows Azure programming patterns for Start-ups, we will provide a systematic guide on how to integrate with Facebook. AppFabric also contains AppFabric applications, an easy way to develop and deploy composite applications. Another interesting feature is the caching feature that AppFabric offers.Read Windows Azure Service Bus: Key Features in full

In the Using a configuration file with Windows Azure Diagnostics recipe, we see how to use a configuration file to do this, which is necessary in a VM role.Read Windows Azure Diagnostics: Initializing the Configuration and Using a Configuration File in full
