Using URLs to Access NNMi Objects

NNMi provides a list of URLs that can be used for accessing most NNMi console objects. This standardized list of URLs and their syntax helps us build the right URL, in order to get the right data object integrated in our selected third-party application.

In this article by Marius Vilemaitis, author of HP Network Node Manager 9: Getting Started, we will cover:

• Generic URLs.

• Form-related URLs.
• Menu item-related URLs.

Using Themes in LWUIT 1.1: Part 1

In an application with a large number of UI components, setting attributes for each can be a tedious task and can also lead to errors. A Theme allows us to set the style attributes for an entire class of components in a single place. This not only simplifies the task of setting attributes for all components of a particular type but also ensures that any newly added component will look just like all the others of the same type in the application. A theme thereby establishes a visual coherence through all the screens of an application.

In this two-part article by Biswajit Sarkar, we shall study themes and their usage in detail. In the first part, we will cover the following points:

• View an existing theme using the LWUIT Designer
• Edit a theme
• Build a new theme
• Preview the new theme on LWUIT demo MIDlet

Using the OSGi Bundle Repository in OSGi and Apache Felix 3.0

This article covers the following topics:

• OBR, the OSGi Bundle Repository
• Using the OBR scope commands
• Installing the Inventory bundles to Felix

Using the Data Pager Control in Visual Studio 2008

When query results exceed the display area then you resort to scrolling and wish you had some way to limit the number of results displayed and comfortable to view without scrolling. Paging functionality which provides an answer to this is therefore a much desired feature. The Data Pager Control in Visual Studio 2008 provides this functionality when you create an ASP.NET web form under .NET Framework 3.5. It can be configured automatically using the GUI, or it can be installed manually after installing the ListView. In this article both of them are described. While the number of items displayed in a list can be declaratively coded, it is possible to set it at page load time as well.

This article by Dr. Jayaram Krishnaswamy describes how you may connect to SQL Server 2008 and display the retrieved data in a ListView Control on a web page. The ListView Control is the only control in ASP.NET that supports the new ASP.NET control, the Data Pager Control. This article shows how the data from a table in SQL Server 2008 is displayed in the ListView and how the Data Pager is configured to cycle the List View items.

Using Storyboards

Starting with the release of Xcode 4.2 and iOS 5, developers and designers now have the ability to lay out the workflow of their applications using the new storyboards feature that has been incorporated as part of the XIB editor in Xcode.

Instead of creating numerous interface files, you can now start dragging and editing all your views in one place with the ability to specify transitions between screens and the associated actions that trigger them.

In this article by Steven F. Daniel, who has also authored the book Xcode 4 Cookbook, we will be gaining an understanding of what storyboards actually are, and how they require iOS 5 or later, as well as familiarizing ourselves with the new work flow that has been implemented within the XIB editor within Xcode.
