In this article by Vinod Krishnan, author of Oracle ADF 11gR2 Development Beginner's Guide, we will take a look at validating and using the model data. Validating data is important as business depends on the data that gets stored in the database. So how do we validate the data? Validation is something that makes sure that valid data is getting stored in the database. Validation could be anything from comparing two fields in a table to multiple validations on a single field involving different columns from a different table.
In any other framework, we would end up writing a lot of code even for a small validation. But in ADF, we do little or no coding at all, and most of the validations are achieved declaratively.
In this article, we will learn the following topics:
- Declarative validation
- Groovy expressions
This article by Jayaram Krishnaswamy shows how you can develop a VB.NET 2.0 application using the integration features provided by the SQL Anywhere database. The SQL Anywhere tools are directly accessible without going out of the Visual Studio 2.O IDE. The article describes a window application with two examples developed with this easy to use integration interface. SQL Anywhere also provides a DataWindow specifically for .NET but this is not included in this article.Read VB.NET Application with SQL Anywhere 10 database: Part 1 in full

This article by Rahul Pitre, will help you try your hands at writing your own HTML mark up to tweak your site.How to install off-the-shelf components to enhance your website is the next skill you'll learn in this article. You'll install a custom FAQ component because the built-in FAQ page doesn't work as advertised.
In this article you will:
- Add an HTML module to your page.
- Write HTML in the HTML module. Chances are that you don't know a lot about HTML. So, you'll take a crash course on a small subset of HTML that will help you to get started with writing your own markup, if you so desire.
- Perform some common page-building tasks such as embedding flash movies, PayPal buttons, and other such external content in your web pages using the HTML module.
- Download and install an FAQ solution that renders a customized FAQ page.
This article applies primarily to a client/server environment where all the content objects are stored on a central server.
In this two-part article by Dirk Manuel, you will learn how to:
- Check in/out a content object
- Display and Revert to an earlier version history of an object
- Restore a deleted content object
- Export content/Import content-backup file

In this article by Will Hacker, the author of the Mobile Prototyping with Axure 7, we will learn about getting our work on the mobile devices. The main reason for creating a prototype is to exercise a design idea to see if it matches the expectations of stakeholders and can be easily used by the people for whom we are designing. If it doesn't, and we fail, that's OK. That's why we make prototypes. Failing fast and learning from that are important parts of iterative design.
In this article we'll look at:
- Publishing prototypes to AxShare
- Creating home screen icons
- Creating app splash pages
Many developers new to Django get tripped up on the vocabulary and purpose of different pieces of the system—models, views, generic views, model managers, and so on. With some functions belonging to models and others to views, it can be confusing to know where to put the logic of your applications.
The view is where most of your application logic will be executed. Before we can work with views, however, we need to look at the URL dispatching system to see how a view is matched up with an incoming request. Once we have seen the URL dispatcher and some working views, we'll take a look at some shortcuts Django offers us to accomplish these actions even more quickly.
You can write entire Django sites without using models, but you'd have a hard time doing that without views or generic views.
In this article by Scott Newman, we will:
- Create a sample application to work with
- Learn how the URL dispatcher works and how URLs are matched to views
- Explore the structure of views
- Build views to display a list of content and content detail
- See how to cut down development time with generic views
- Examine when to use regular views instead of generic views

In this article by Rebecca Fitzhugh, the author of the book vSphere Virtual Machine Management, has explained the basic concepts of the virtual machine. Ever since VMware was founded in 1998, it has been creating stable x86 virtualization platforms that allow multiple guest operating systems and applications to run on a single physical server. Before an administrator can begin creating and configuring vSphere virtual machines, it is important to understand what a virtual machine is and the concepts behind virtualizing hardware.
In this article, you will learn:
- What a virtual machine is
- Components of a virtual machine
- Why to use virtual machines
- Files that make up a virtual machine
- The four primary resources

Visual Basic for Applications (VBA) is a programming language built into Microsoft Office applications. As you improve your skills in any application from the Office System, you will eventually realize that although Microsoft Office applications offer a large number of tools, they do not offer everything you need to perform your daily chores. Such chores may include creating a corporate custom-format, a custom function that calculates commission payments, and so on.
Thus, VBA works as a gap-filler; in other words, its main purpose is to ensure that you can do whatever you need to do in your job.
In this article by Robert Martin, author of Excel Programming with VBA Starter,you will get to know a bit about VBA, its basic features, what you can do with it, and how you can put it to work with a view to facilitating your daily work, by automating common tasks.Read Visual Basic for Applications (VBA) in full
