What is the possibility of a singleton reference to be lost. Well I created a swf singletonpara a store containing some sound features of the software that I created and it's one time or another error saying that the reference is null

Here is the related code, I think:

I opened up a file that was created in cs3 flash with cs5 flash and we have some text that is bold in our actionscript code. now when i load that file with cs5 the bold text drop's out of bold and is just plain text. Does anyone know if there is a quick fix for this because what was there before the <b></b> is not working now.

My problem is that scaling the pic inside of flash makes the resolution of my pic very crappy. Is there any way to use a motion tween and scale my pic without losing the resolution and without having to import the pic frame by frame from photoshop?

Has anyone noticed how the 3D tween causes a loss in visual quality of the movieclip? For example, if I have text within a movieclip, and then put a 3D tween on that movieclip, the text becomes almost blurry (even when the tween is complete). Then if I take the 3D tween off the movieclip, the text goes back to being perfectly clear. It's not just text though; its any content with a 3D tween on it; text is just the most noticable. Is anyone else dealing with this?
Is there something that I'm missing, like a quality setting on 3D tweens?
P.S. there aren't any blur filters on the movieclip. I checked
i have a mobile application that i am creating in Adobe Flex (Flash Builder 4), and i am trying to create a zoom function. The one i have works, but the point is to be able to more easily read words that are in the image (the images are .jpg files). The images are 2550x3300 originally, but as soon as you zoom, the image quality reduces drastically, and nothing is readable.

So we're trying to come up with a way to automatically assess the "quality" of streams published to an FMS. So far, I've come down to 3 different statistics:
* Round-trip ping time to client (using the Client.ping() method and Client.getStats().ping_rtt.
* A home-grown jitter calculation that compares the deviation between wallclock and media time for an inbound stream, e.g., I get N+/-M seconds of media over a period of N seconds of wallclock time. How big is M on average? (uses Stream.time and Date.getTime()).
* How much packet loss are we getting?
For this third metric, I have the client sending up period reports containing tuples of <media_time, cum_bytes_sent>, where media_time is provided by NetStream.time and cum_bytes_sent is provided by NetStreamInfo.byteCount. I'm then comparing these samples to a similar set of samples obtained on the server via Stream.time and Client.getStats().bytes_in. Unfortunately, these two data sources do not seem to be measuring exactly the same thing. While they are close to each other, the received bandwidth (e.g., measured by the server) always seems to exceed the sent bandwidth (measured by the client) by a small amount (e.g., 0.5% to 2%) on a clean network.
The goal of this whole exercise is to enable to server to automatically detect when a client is having problems (either network or local CPU). Among other things, this will trigger us to tell the client to try sending a lower-bitrate stream.
So, my questions:
* Is there a method for me to reliably calculate (or obtain) a packet loss factor? With something like RTP, I could simply look for holes in sequence numbers, but I don't see any APIs that would give me that sort of information via FMS (our inbound streams are usually RTMFP).
* If there isn't a way for me to get a clean packet loss factor, is there another quality metric I should be looking at?
I'm using Flash CS4. Everything functions as it should when CS4 previews the swf after compiling it. However, after embedding the flash item in a webpage, if the textArea loses focus within the flash piece, the textarea's built-in UIscrollbar resets to the very top. Here's the kicker: if I add a FOCUS_OUT event listener to the textArea to store the current scrollbar value, I find that the scrollbar value has been reset to minimum even before the FOCUS_OUT event is triggered! WTF? I think this is occurring because the textArea's htmlText propery is dynamically populated. Adobe AIR has advanced methods for handing HTML, but not simple AS3, oh no. How obnoxious. What can be done?
View 1 RepliesI am looking at the singleton design pattern and trying to really understand what is going on here. But I have some questions that it would seem my logic and/or the way I am reading this is wrong. Take the following code for example
[Code]...
I can't understand why should I even use the Singleton pattern in ActionScript 3. Can anyone explain me this? Maybe I just don't understand the purpose of it. I mean how it differs from other patterns? How it works? I checked the PureMVC source and it's full of Singletons. Why are they using them in the View, Module, Controller?
View 2 RepliesIn the Singleton design pattern you can throw a runtime error if the instance has already been created. But this doesn't work when your singleton class extends another class and has to call super() in its constructor, because (for some reason) you cannot call super() if you've already called throw(), or in fact, you cannot compile code that has a potential call to throw() (for example, in an IF statement) that comes BEFORE that call to super().
