Remove tags from a string in AS3

A couple of months ago I integrated a nice WYSIWYG editor written in Flex in my CMS. It worked fine, till yesterday I needed to add more features like text formatting and font color changing. As you know the Flex RichTextEditor component adds some additional tags that I definitely don't want to send to the database. So I wrote a simple function to remove these tags. more

Load MySQL data in Flash with AS3

There are some things that I'm doing in almost every project. Loading of data in Flash is actually one of them. In this article I'll show you how to load information from MySQL database. We will use PHP as a junction between the Flash and the database. You need an Apache server like XAMPP or EasyPHP installed or just a hosting account that supports php. more

How to protect your SWF file

Is there any way to protect your flash work? To be honest the answer is NO. As you probably know everything that is uploaded on a web server and is accessible from a web browser is downloaded to the users' computers and could be found in the temporary directories. Once someone gets your swf file he could use one of the dozen decompilers to reproduce the .fla and .as files. Anyway, there are still some ways to make stealing difficult. more

Creating simple WYSIWYG editor with AS3 (Flex)

There are dozen of JavaScript WYSIWYG editors available, but most of them are too complicated and a little bit buggy. From time to time I'm using my own tool to provide such kind of functionality. It accepts and exports valid html. I decided to share it with you and explain how I built it. more

AS3: runtime font loading (embedding)

Flash is wonderful technology and has many advantages. Before a couple of years it was really popuplar to use it for displaying fonts that are not installed on the user's machine. Flash is still powerfull tool for such kind of tasks. These days I worked on a project which had to use a lot of fonts. It wasn't possible to embed all of them so I decided to implement runtime embedding. more

Simple command line parser in JavaScript

There should be some super cool RegEx, which I can use. However after short research I wasn't able to find it. So, I created a simple function which does the job. more

Javascript string replace and regular expression

The replace method in JavaScript is pretty much the same as in the other languages. Replace part/s of a string with something else. However, there are some tricky moments and I wanted to write this article, because I met this problem several times in the past. Actually, very often I use my blog as a documentation for myself and this is one of those cases. Probably I'll be in the same situation after week or so and I'll just check here for the proper solution. more
