Thanks 回答1: Here is a link that explains how to develop for

问题 What is the workflow for creating an AIR application in Flash Builder and how does it differ from Flash Professional? I am familiar with Flash Professional, but I'm trying top wrap my head around FB, but I'm coming from a stint in iOS development and Flash Pro is driving me crazy. (I have difficulty with classes mixed with the timeline, but I think that MXML might be a good substitute for the timeline.) (Bonus: What are some good online resources for learning MXML?) 回答1: This is a hard

问题 I'm trying to track the progress of a file upload in AS3, and I'm getting strange behavior. When I select a file and upload it, the progress is instantaneously 100% even if the file is 10 or more megabytes, but it's not finished. The onComplete event is fired about 30 second to a few minutes later (depending on file size) when the file has really finished uploading. I've tested this locally and on the server, the behaviour is the same. Has anyone else experienced this? Very frustrating ...

问题 I have created a custom even class which is pretty basic. But when calling an event and then relaying that event to another class I have encountered the "cannot transform thisEvent into thisOtherEvent" error. I realize this is because I needed to override the Clone function in my custom event like so: package com { import flash.disply.*; import flash.events.Event; public class MyCustomEvents extends Event { public static const SOME_EVENT:String = "some_event"; public var info:Object; public

问题 I am loading an image using a Loader. Once loaded, I can get the bitmap data using Bitmap(event.target.loader.content).bitmapData . However since the images I am loading are quite large (around 2000 x 1600), I would like to reduce the size and create a new smaller bitmap maybe 200 or 300 pixels wide, sort of like a thumbnail. I think it has to do with creating a new BitmapData with the new size. However I am not able to get that working properly. Any ideas? 回答1: Not tested, but this should

问题 It's probably a no brainer, but I've spent the last 40 minutes or so looking for it to no avial. I have a Canvas control with a fixed width and a horizontal scrollbar. I'm trying to find the actual width of the control. The .width (fixed width) + the part being revealed by the scrollbar. I tried explicitWidth, width + maxHorizontalScrollPosition, and some other combos but non of them hit the spot. 回答1: Well as it seem width + maxHorizontalScrollPosition is indeed enough. The problem was with

问题 Is it possible to connect any database from flex directly? 回答1: Not unless you use Adobe AIR for desktop at which time you'd be using the SQLLite api's to create/connect to a sqlite database file. http://livedocs.adobe.com/flex/3/html/help.html?content=SQL_01.html Anything else is going to require a back end service to handle such transactions. 回答2: You can use asSQL as mentioned by michael, or use the Adobe Air runtime. However, this must be said about using this library: It is EXTREMELY
