This week's featured article, Trace Function Enter, Exit and Leave, continues the theme (from last week's featured article) of log based debugging.

The article shows how the code can be instrumented so that it will generate logs whenever a method is being executed.

Your application does not work? Apply the logging technique described in the article and you will soon find out what was the last of your methods that was executed, and whether it was successful or not. Once you know that, you can then focus your attention to the faulty method, add more detailed logging if needed, and eventually identify and correct the problem.

The logs collected will show when the execution pointer is entering the targeted method and when it exits, but more than that, it will also show whether the method had a clean exit or whether it was forced to quit by a leave. On WINSCW target (that is, an emulator) the author employs an assembler code based trick which allows retrieval of method's exit code. To further enhance the topic, it would be great if someone could contribute a similar trick for the device targets so that the information can be collected when running on the real phone too, not just on the emulator - such contribution would not go unnoticed!

This week's featured article, How to use RDebug, provides information about a basic debugging technique: logging.

The article shows how to use a Symbian defined API, RDebug, in order to generate logs which can then be captured in real time either by the IDE or by other specialized tools.

This technique is used intensively in the S60 emulator, where many of the system components are using it to dump potentially useful log data. Unfortunately it gets to the point of having too much log content so that useful information may get lost in a sea of text. This article shows how the IDE can be extended with an existing 3rd party Eclipse plug-in which will help in finding and highlighting your custom log messages.

This week's featured article, S60 Sensor Framework, is written by Dr. Jukka Silvennoinen (better known as symbianyucca).

One of the most active technology areas for S60 developers is, no doubt about it, Sensors. Although officially supported only by the Nokia 5500 Sport, developers have managed to find resources that enable them to use the "hidden" sensors on some other devices (such as the Nokia N95) and now sites such as youtoube.com are filled with application demos. For a list of sensor-based applications, click "here".

The S60 5th Edition release introduces a platform-level Sensor Framework. This new standardised set of APIs allows developers to write sensor-aware code that can be run on all S60 devices and utilises the sensors that the manufacturers have provided on them. No more fighting to identify "secret" APIs and magic UID values or switching between this vendor's API and the totally incompatible API of the other vendors!

On a related subject, S60 5th Edition also includes the S60 Platform Services framework, which provides various native platform features (including sensors) for WRT widgets and Flash Lite applications.

This week's featured article gives an overview of the S60 Sensor Framework, explains how it should be used, and also provides an example application - all you need to get started in using this new set of APIs.

This week's featured article is Dynamic Layout control for Flash Lite written by Risalmin.

How to effectively adapt to different screen orientations and resolutions is one of the key issues developers face when designing mobile applications. Instead of making separate, optimized versions for both orientations and for each resolution, there are also more sophisticated techniques.

This article provides one approach and a template for dynamic layout control in Flash Lite. The same basic techniques can also be applied when writing applications in other programming languages.

First, an abstract background is applied to give a similar look regardless of the orientation. Next, separate movieclips have been created for softkeys, the title, and for the actual real estate area. The real estate area always remains 240 x 240 pixels and does not need to be resized. Also the softkey area is designed in such a way that the texts are not resized.

The template is easy to use. Just place your content in the real estate area, in the title element, and in the softkey element.
