Three Very Good Flex Resource Sites
Andrei Ionescu | 07.03.08 | Permalink | Comment?

Today I found this three sites filled with flex resources:
- DeGraFa (Declarative Graphics Framework)
- ScaleNine
- Flexgeek
DeGraFa is a framework made to do a much easier job when working with shapes, events, skinning, etc. ScaleNine is a collection of themes to use in flex applications and FlexGeek is a blog with very useful examples of how [...]

Spell Checker in Actionscript 3: Spelling Plus Library (SPL)
Andrei Ionescu | 06.03.08 | Permalink | Comment?

Big RIAs need good interaction with the user. In big applications (like Buzzword, etc) with intensive text processing is a must to have implemented a spell checker.
A very good spell checker that is built in Actionscript 3 is Spelling Plus Library (SPL) by gSkinner – the license is here and can be bought from here.

When speaking about RIA one of many nice usabilities is that to be able to give feedback to the user when it comes to critical actions like submitting important data, saving work, etc. Let’s have the following example: You log in into a RIA with your user and password, you do changes to your data [...]

Flex and PHP web-service
Virgil Cristea | 17.02.08 | Permalink | 3 Comments

Yesterday I had to do a small flex application that resided on a server with php. Since I required a connection to mysql I wanted to use the same class I did before to connect to web-services. But PHP does not support web-services (and WSDL) by default.
So after I did some search on the net [...]

Three RIA Platforms Compared
Virgil Cristea | 03.02.08 | Permalink | Comment?

As time passes the applications tend to move from thick software to thin web applications and they need to be platform and browser independent. This has happened because of the need of having applications that work on all platforms/browsers, have an easy way of getting the server side data, have more reach and also [...]

RSL further details
Virgil Cristea | 08.01.08 | Permalink | 1 Comment

As I have played with RSLs more I saw something surprising: If I compile the swc into a swf the resulting swf is bigger (almost twice) as it should have been. When you use compc to create a SWC, the SWF inside the SWC contains a lot of unnecessary stuff when used as [...]

How to create a swf RSL from a swc and how to use it
Virgil Cristea | 08.01.08 | Permalink | 1 Comment

In a previous article I told you about the benefits of RSL’s. But you need also to know how to create them from a swc and how to use them.

Andrei Ionescu | 31.10.07 | Permalink | 3 Comments

These days I started to study about MVC (Model-View-Controller) implementation for Flex. Although I used a lot MVC and MVC Frameworks in other language (PHP 4 & 5) the Cairngorm MVC Framework is a bit more complex.
For a better understanding I found the following interactive diagram where you can view which part of the code [...]

In my previous post I started to talk about how you can see the same trace messages you were used from developing but this time in the “Release”.
This is done with the help of the Log class (mx.logging.Log).
Let’s take a look at some pieces of code (full code can be provided per request).

Virgil Cristea | 25.10.07 | Permalink | Comment?

One of the most common problems in the RIA applications that require login/logout and also some saves is how to prevent the user from closing the window/tab when there is unsaved information?
The answer is simple: FABridge.
This functionality allows you to catch the unload event from javascript and execute your flex code.
Here is how:

Debug/Logging Client-Side – Part 1
Virgil Cristea | 24.10.07 | Permalink | 2 Comments

One of the most common problems in developing new applications is their debugging. There are several methods to do this in Flex (trace, alert – like somebody once said: “Alert till death”). But what happens if you want the same logging that you had on your work environment to also be available when the application [...]
