Re: [SPAM] [flexcoders] How to call a Actionscript function in a UI child from UI father ?
Also you would want to make all functions public that are to be accessed by
outside objects. I see you marked getFileSize as private.

In the Flash days, this was easily solved by having one small SWF with preloader that would load the main SWF in empty movie clip. Is something like this possible in Flex? I did a small experiment with loading the Flex app into Flash SWF, but then the sizing and alignments were lost. I also tried loading a Flex app into a smaller Flex app, but still there was a blank screen for quite a while. It's a huge usability issue knowing that users leave after 8 seconds, which is actualy true looking at google analytics reports. I've checked numerous blogs about custom preloaders but only found that all of them have the same issue.

Re: [flexcoders] Which Unit Testing Framework to use?
Thanks Errol, your blog is very useful. I found FlexUnit most discussed and endorsed by Adobe, that's why assumed it's a leader of the pack, I didn't do any tech research on it though. Maciek, thanks for your feedback on FlexMonkey, it definitely gives me enough confidence to give it a go.

I first found out about it from this list earlier this week, and about a day later, I started moving our tests to it (from FunFX). Initially getting it working in Flex 3.0 was a pain (it is built against a library that was built against 3.1, which introduced some breaking api changes), but now that it's running, it's a great tool. It records interactions and essentially generates FlexUnit tests for you (in theory, it can generate test for any unit testing framework with asynchronous test case support, but it's currently tied into FlexUnit).

Re: [flexcoders] Re: AIR app uninstall issue - database stays in applicationStorageDirectory forever?
Well, at least if we would be able to know that we're installing it and not just running it.

Re: [flexcoders] Re: Numbers gone crazy: 5 - 4.8 = 0.2000000000000018 ?
Yes, toFixed() is a better option. It still does not solve the problem as we don't know to what value to fix the numbers to achieve consistent behavior. In practice using something like toFixed(8) for every Number should do the job, but then again we can't be sure. I also found this blog that seems useful: http://www.zeuslabs.us/2007/01/30/flash-floating-point-number-errors/ On Mon, Jul 21, 2008 at 3:33 PM, Kuldeep Atil [EMAIL PROTECTED] wrote: well, u can use number.tofixed(2); --- In flexcoders@yahoogroups.com flexcoders%40yahoogroups.com, b_alen [EMAIL PROTECTED] wrote: Here is how I arrived at this: var res:Number; var a:Number = 5; var b:Number = 4.8; res = a - b; trace(result: + res + , a: + a + , b: + b); The trace clearly shows that the value of a is 5, and the value of b is 4.8. However the end result is clearly shown as 0.2018. Ok, I wanted to create a workaround where I will make sure that b is really 4.8, and I used toPecision() method. var b1:String = b.toPrecision(2); var b2:Number = Number(b1); trace(b1: + b1 + , b2: + b2); res = a - b2; trace(result: + res + , b1: + b1 + , b2: + b2); Again with same result. b2 was traced as 4.8, but the end result still showing 0.2018. As this can of course break all further calculations I had to make sure result is really holding a value that it should, based on all mathematical logic. So I did this: var res1:String = res.toPrecision(2); res = Number(res1); trace(result: + res); I got the expected result and the value of res is now 0.2. This is however very ugly, in case I'm not doing something wrong. Every time we expect a floating point value in our calculation we have to handle it to ensure the proper value is calculated, because what Flash calculates is just wrong. Also, every intermediate calculation has to be stored in a variable converted to String with toPrecision and back to Number for future use. I really don't know how to properly handle this and would appreciate any advice. Imagine the shopping cart system with this sort of unpredictable behavior. For the end, here's one more weirdness: var c:Number = 488.8; trace(c: + c + , c.toPrec: + c.toPrecision(2)); Traces out c: 4.8, c.toPrec: 4.9e+2 Thanks, Alen var c:Number = 488.8;
Re: [flexcoders] No of Lines of Code
We used externalis once, program for this once. Can't remember the name
exactly but it's LineC or something like this. Do some Googling there are
plenty of free options available.

As I understand from my reading, the W3C specs state that POST methods do
not cache. There are posts on this list about it, and I am sure you could
look into the specs themselves. I have just always used POST, and never had
any problems. Aspx is nice because Request(myParm) handles both post and
get parameters.

*Subject:* [flexcoders] httpservice and repetitive calls
I'm using the httpservice to make a call to an aspx page which runs a
query and returns the results. This is fine, but if I try to run the
same call again, the service is not actually going out to make the call,
but rather just returning the results from the previous call. I know
this because the aspx page logs each call made to it. I always see the
first call, but no subsequent calls come through if I post the same
data. If I send a different set of data, the call works fine, but then
will not post that data again. Any ideas on why it doesn't want to
actually make the call? Below are the relevant pieces of code:
script ...
public function lblClickHandler(event:Event):void{
tgtdata = event.currentTarget.data.toString();
customer_id = event.currentTarget.data;
useHttpService();
}
public function useHttpService():void {
userReq.url = dstURL; //set in another part of the code
userReq.method = GET;
var Obj:Object = new Object();
Obj.w = wispid; //wispid is just a number that is set
elsewhere
Obj.i = tgtdata;
userReq.send(Obj);
}
...

Re: [flexcoders] Flex Efficiency
Alex, do you have any more info on the subject, especially what are the workarounds? I too am using lots of really tiny and simple external swf animations and performance is really really bad. If I remember correctly it's much worse than Flash Player 7. The profiler will help you find inefficiencies in your app. Loading lots of SWFs is, of course, going to eat resources.
Re: [flexcoders] Flex Efficiency
Thanks, Alex. Unfortunately that is the main problem as I let users add graphics on the fly to create their artwork. And graphics are small swf animations, really simple ones. How is adding swf's different in this regard than adding jpegs, gifs or png's on the fly? Also is there a limit set? Because after adding lots of them, some of them just start to disappear and all I do is stack them with addChild(). Can we expect same performance issues when adding lots of visual objects such as buttons, canvases, etc...? If I add 100 simple swfs and 100 button controls, will it behave the same?

Re: [flexcoders] Re: Cairngorm Event Question
First you have to understand the concept of Cairngorm and then UM extensions. Especially in light of what you're trying to achieve. Recoding your project in Cairngorm manner might be an issue depending on how far are you with it and how many developers are on it. It is very straightforward otherwise and I would most definitely recommend you to start using it. If you need some guidance on Cairngorm let us know, but the good starting point would be this: http://cairngormdocs.org/, read the six part article that you find there. The basic idea behind Caringorm is a simple MVC architecture where you make the view as dumb as possible, it just dispatches the events based on (user) actions.

It looks interesting but a little beyond me. Do you have any recommendations for getting more information on using this than what is supplied at google code??

[flexcoders] Re: Accessing nested DisplayObjects programatically
I'm not trying to acces the children from MXML file, but from a Controller class. My app is set up in the following way: application script var ctrl:Controller = new Controller(this); script !-- all the nested ui elements here -- /application What I wanted to achieve is that I don't have to have any code in the MXML file (well appart from instantiating controller) and that I controll all the UI from a Controller class which upon construction creates the references to all the UI elements I'm interested in. Now, this works by casting to Conatainers and drilling down with the getChildByName() but I don't know if I want to do that anymore. Beacuse: I heard that in Adobe labs they dropped this concept of a controller helper and are instead relying quite heavily on the code inside MXML. Heavily means all the UI stuff. I'm quite new so I don't know which approach to take. I'm personally n favour of keeping as much as possiblenthe classes, but if the Adobe folks say different then I'm sure they also know what they're talking about. --- I have heard the Adobe folks advise against using getChildByName() because name is internal and may not forever equal id. Why aren't you just using id?
