NAV 2009: Reports

by David A. Studebaker | November 2009 | .NET Microsoft

In this article by David Studebaker, we will review different types of reports and the Report Designer tools that are a combination of pure NAV (the C/SIDE Report Designer) and the Visual Studio Report Designer that is tightly integrated into NAV 2009.

Some consider the library of reports, provided as part of the standard NAV product distribution from Microsoft, to be relatively simple in design and limited in its features. Other people feel that the provided reports satisfy most needs because they are simple. Their basic structure is easy to use, and made much more powerful and flexible through the multiplier of NAV's filtering and SIFT capabilities. Some say that the simplicity of the standard product provides more opportunities for creative enhancement.

The fact remains that NAV's standard reports are basic. In order to obtain more complex or more sophisticated reports, we must use the Report Designer features that are part of the product. Through creative use of these features, many different types of complex report logic may be implemented. You can also use NAV reports to feed processed data to other reporting tools such as Excel or "third-party" reporting products.

Navigating Pages in XAML Browser Applications

by Jayaram Krishnaswamy | December 2009 | Microsoft Web Development

XAML browser applications also known as XBAPs have the features of a web application as well as those of rich client applications leveraging most of the capabilities of WPF. As web applications they can be published to a web server and can be browsed on IE and Firefox.

This article by Dr. Jayaram Krishnaswamy shows how to create a XBAP application using Visual Studio 2008; how to navigate between pages in the application; and how to deploy the application to the local intranet web server using built-in support in Visual Studio.

Navigating Your Site using CodeIgniter 1.7: Part 1

by David Upton | November 2009 | MySQL PHP Web Development

In this article series by Jose Argudo Blanco and David Upton, we will cover some important topics, such as the MVC pattern and how CI handles this pattern, and also, we will make an example controller just to see how all this works.
We will briefly look at the theory behind MVC, and then at the way CI organizes itself internally. In particular, what goes in those different folders and how do they communicate?
In this article, we will cover the following:

  • How MVC helps to organize a dynamic website
  • The process by which CI analyzes an incoming Internet request and decides which part of your code will handle it
  • What the code does
  • CI syntax rules
  • The different type of files or classes you can find—or write for yourself—on a CodeIgniter site

Navigation Stack - Robot Setups

by Aaron Martinez Enrique Fernández | October 2013 | Open Source

This article by Aaron Martinez and Enrique Fernández, authors of the book Learning ROS for Robotics Programming, talks about configuring your robot to use it in the navigation stack. Now, in this article, you will learn something that is probably one of the most powerful features in ROS, something that will let you move your robot autonomously.

Thanks to the community and the shared code, ROS has many algorithms that can be used for navigation.

First of all, in this chapter, you will learn all the necessary ways to configure the navigation stack with your robot. In particular, we will cover the following items in this article:

  • Introduction to the navigation stacks and their powerful capabilities—clearly one of the greatest pieces of software that comes with ROS.
  • The TF is explained in order to show how to transform from the frame of one physical element to the other; for example, the data received using a sensor or the command for the desired position of an actuator.
  • We will see how to create a laser driver or simulate it.
  • We will learn how the odometry is computed and published, and how Gazebo provides it.
  • A base controller will be presented, including a detailed description of how to create one for your robot.
  • We will see how to execute SLAM with ROS. That is, we will show you how you can build a map from the environment with your robot as it moves through it.
  • Finally, you will be able to localize your robot in the map using the localization algorithms of the navigation stack.

Nesting, Extend, Placeholders, and Mixins

by Ben Frain | June 2013 | Web Development

In this article by Ben Frain from the book Sass and Compass for Designers, we will look at the capabilities of Sass and Compass when it comes to actually writing styles. These are the core capabilities likely to be employed when working with Sass and Compass day-to-day. In this article, we will learn:

  • What nesting is and how it allows styles to be modularized

  • How the @extend directive allows us to extend existing rules

  • To use placeholder selectors to extend styles only when needed

  • What mixins are and how we can use them to easily produce oft-needed code

  • How to write a mixin for our own purposes

NetBeans Platform 6.9: Advanced Aspects of Window System

by Jürgen Petri | August 2010 | Java Open Source

The NetBeans Platform provides the requirements for window management via its docking framework, known as the NetBeans Window System. In the previous article we learned how to create new windows, that is, TopComponents, and also learned how to position them.

The NetBeans Platform also provides an API to let you programmatically access the window system. Together, the window system and its API fulfill all the requirements described below, letting you concentrate on your domain knowledge and business logic rather than on the work of creating a custom window management facility for each of your applications. In this article by Jürgen Petri, author of NetBeans Platform 6.9 Developer's Guide, we will learn:

  • How to customize the default window layout
  • How to group views so that they open and close as a unit
  • How to change the persistence of views across restarts of the application
