I’ve moved the Pantomime framework into an XCode 3 project and changed some settings to make it compile.
Pantomime is provides classes for mime coding/Encoding, SMTP, POP3 and much more. Since Apple dropped support to send emails using Cocoa, Pantomime might be a good replacement.
Find the zipped XCode project folder here.
Here’s a small helper class CPreferencesManager which manages application preferences by means of a key/value set, which I added as a comment to coldfusionjedi‘s nice blog:
Sample usecase: Make window positions persist after relaunch of an application:
In case you’d like to learn how to visualize data using Flex or AIR, check this video and see how easy it is to visualize data using DataGrid, AdvandedDataGrid and a CoverFlow component of Doug McCune.
Actually, the author of the video uses one single data source and visualized it using different data-driven components.

Besides the full features Flex debugger, the trace() method is a useful way to inspect variables during debugging a Flex application: If you start a Flex application in Debug mode, trace() prints the value of the passed expression to consol.
Another way is to register a variable for permanent traceing. This way, the variable gets traced, each time it changes its value.
Based on the following TATRace component, you request tracing of a variable using a small piece of MXML. Suppose you’d like to trace a variable ‘traceableVariable’, then you just add [Bindable] in the line just before the declaration of the variable. This enables the variable to be referenced as ‘{traceableVariable}’.
Mark a variable as traceable
To trace each change of traceableVariable, add this element in your main MXML file
As always, when I give a new programming system or language a try, I implement a small project.
The project has to be small, to not waste too much time. And the project has to be non-trivial, to really figure out the potentials of the langage and runtime.
In case of Flex, I started to implement a client-side DB-viewer.
These areas are widgets and can be controlled through the admin page.
