In general, an SWF from a web-server cannot read files from the client machine. But it can upload user-selected files from the client machine to the server. An operating-system specific dialog box prompts the user to select the file to be uploaded to the server. Hence Flash cannot read any file it wants, only those … Read more
Adobe does this as a sort of security measure to ensure users are the ones messing with files rather than potentially harmful code. My understanding is that they enforce this by only allowing handlers of (click?) events that originate from UI components to execute the FileReference methods, so generating your own events programmatically will not … Read more
In realy I advise to you don’t to use this too much… it is very expensive. Adobe need to create a native function to return this to us. But, for now… try this: You will need to cause a explicit coercion to get it! Because when you make and explicit coercion you get an Error … Read more
Update Nov 2018: It would appear that Structure101 (new download page) no longer has an ActionScript variant. Original answer, links outdated: Download Structure101g and select the Actionscript flavor after installing the software. I’ve confirmed that it is able to map out class level and even function call dependencies in Flex/AS3 projects, and generate a visual … Read more
You are trying to write a DisplayObject into the file directly, this is prevented by Flash engine due to the way Flash handles default serialization of any object. In order to save a DisplayObject into the external resource, you need to employ IExternalizable on that object’s class and any class of objects you will plan … Read more
I created an ActionScript TimeSpan class with a similar API to System.TimeSpan to fill that void, but there are differences due to the lack of operator overloading. You can use it like so: TimeSpan.fromDates(later, earlier).totalDays; Below is the code for the class (sorry for the big post – I won’t include the Unit Tests 😉 … Read more
This: \d{1,3}(,\d{3})*(\.\d\d)?|\.\d\d matches all of the following numbers: 1 12 .99 12.34 12,345.67 999,999,999,999,999.99 If you want to exclude numbers like 123a (street addresses for example), or 123.123 (numbers with more than 2 digits after the decimal point), try: (?<=\s|^)(\d{1,3}(,\d{3})*(\.\d\d)?|\.\d\d)(?=\s|$) A little demo (I guessed you’re using PHP): $text = “666a 1 fd 12 dfsa … Read more
This is my generic solution for the problem (I have blogged about this here): var toFixed:Function = function(number:Number, factor:int) { return Math.round(number * factor)/factor; } For example: trace(toFixed(0.12345678, 10)); //0.1 Multiply 0.12345678 by 10; that gives us 1.2345678. When we round 1.2345678, we get 1.0, and finally, 1.0 divided by 10 equals 0.1. Another example: … Read more
The syntax is a little different for URLRequest, but the idea’s the same: private function doWork():void { var req:URLRequest = new URLRequest(“http://yoursite.com/yourservice.ext”); req.method = URLRequestMethod.POST; req.data = new URLVariables(“name=John+Doe”); var encoder:Base64Encoder = new Base64Encoder(); encoder.encode(“yourusername:yourpassword”); var credsHeader:URLRequestHeader = new URLRequestHeader(“Authorization”, “Basic ” + encoder.toString()); req.requestHeaders.push(credsHeader); var loader:URLLoader = new URLLoader(); loader.load(req); } A couple of … Read more
The theoretical answers from everyone else are all neat, but let’s be pragmatic. ActionScript provides the tools you need so that you don’t even have to write a loop in this case! First, note that Math.min() and Math.max() can take any number of arguments. Also, it’s important to understand the apply() method available to Function … Read more
