[flexcoders] Re: Using modules and remote objects

[valdhor]

I do this all the time. My main application is a shell that loads in the app's 
layout and loads the menu's based on a users access level. This app then loads 
whatever module the user is interested in. Each module has all of its 
functionality encapsulated including its required remoting. This is all using 
Flex 3.x (Whatever the latest version is) as I don't have time to port it to 4 
yet.

Can you post some code? Flex as well as server would be good. PHP would be even 
better.

[flexcoders] Re: flashBuilder.ini

[valdhor]

First off, are you running 32 bit or 64 bit Java? Not to mention Eclipse (Flash 
Builder). NB: Flash Builder is built on Eclipse. It looks like it is 32 bit 
(win32 mentioned in plugins line). This will give a maximum heap size of 2GB 
which you would not be able to set it to as there would not be any memory left 
to work with. Also, a DLL may have loaded into the memory area that the JVM 
wants to use for heap (The JVM needs a contiguous block of memory). Java is 
intelligent enough to give an error if you set initial(Xms) or maximum(Xmx) 
heap size too high.

Some posts that might help you understand these settings...

My rule of thumb is that if there is data. like a database. then yes. Flex

Subject: [flexcoders] I don't know if I need Flex (please help me to decide)

 

  

Hi! I will try to explain my situation:
I'm a Flash developer (not a good one, just one more...), I know AS3, OOP, I
can read MXML and I've read a lot about Flex in the last days, although I
have never used it.
And there's a reason for that, the SWF size, I'm from Argentina, and here
internet is really slow in many places (mine is 128kbps for example, so to
load a SWF of just 150KB I need to wait approx. 10 seconds)

I was reading about RSL's to solve that, and it looks good, but I think
could be a lot some "problems":
1) the first download will be very slow
2) if my RSL is not cached for any reason then nobody will be visiting the
site again
3) what happens if I need to protect some project? I've read an article
about Nitro-LM with RSL's (I don't know if it's the best option, for the
moment I have never protected any code...), but if our RSL is encrypted,
will be cached then?
4) I don't know, is there any other problem with RSL's? what do you think?

I was reading about using Flex without the Flex Framework, and I like that
idea, but what happens if I need a component? just one? I need to include
again +200KB of code?

I was thinking in working purely in AS3 and reusing some classes from Flex
without embedding all the framework (my first goal is to make a really light
version).
I want to use Flex because there are some classes and components that I
don't have in Flash, and I need them, like RemoteObject.

So, I need some of the Flex Classes but I need a very light SWF.
Is possible to achieve that with Flex?

Thanks!
Enrique.

[flexcoders] Re: Line Chart, I have a X value, how can I find the Y value?

[Mike]

I did something like this for EBay.  I defined a hierarchy of Equation classes, 
including linear, nth order polynomials, power law.  The base Equation class 
provided common functionality such as data initialization and solving for the 
unknown gien a variable.  Applications could then be written that called the 
library function in real time, so a mouse could be tracked while live X and Y 
intercepts were displayed, etc.  Sorry I can't offer the source code.  
Hopefully this gives you an idea of how you might proceed.

[flexcoders] Re: Using modules and remote objects

[Mike]

I recently did something like this for Cisco.  They needed a way for a 
sub-Application to invoke a method in another sub-Application, which might not 
be loaded.  The solution was to derive the sub-Applications from a common base 
class and use the main Application as a broker.  The broker listened to 
function invocation request events.  Results of the method calls were made 
available by a custom event that was dispatched by the called method upon 
completion.

Here is a clue to how to implement this type of mechanism: the SWFLoader that 
loads a sub-Application has a property called content, which is actually the 
sub-Application's FlexGlobals.topLevelApplication once the sub-Application 
loads.

Confused? I created a UML sequence diagram, a static object model diagram and a 
text narrative to document how the mechanism worked.  Anyone else attempting 
something similar is well advised to do the same.

[flexcoders] Re: flashBuilder.ini

[Mike]

I am using a 32 bit JDK because as you have guessed FB is not 64 bit capable at 
this time.

BTW, I have discovered that command line vmargs do not override settings 
specified in the ini file, contrary to the docs.  In other words, given the ini 
file I posted earlier, the following does not affect Xmx:

"E:\Program Files\Adobe\Adobe Flash Builder 4\FlashBuilder.exe" -vm "E:\Program 
Files\Java\jdk1.6.0_20\bin" -Xmx1500m

It would be more helpful to post complete and working ini files that provide 
>800M of heap.  "In theory there is no difference between theory and practice. 
In practice there is." -- Attributed to Jan L. A. van de Snepscheut, Yogi Berra

QED You have only 2GB of usable memory.

> >800M of heap.

One person's ini file that works is probably not going to work on your system. 
It's all dependent on the DLL's that are loaded and where they position 
themselves in memory (They generally have a preferred location). In your case 
you have a loaded DLL (or more) that is/are loaded in memory somewhere inside 
the 2GB that is available. The JVM has determined that there is a contiguous 
800MB of memory and limits you to that.

Someone could post an ini file that works for him/her but they would have 
different DLL's loaded so that ini file will not work for you.

You can either try to unload the various DLL's you have or find some way to 
move their preferred memory location.

[flexcoders] Re: I don't know if I need Flex (please help me to decide)

[enridp]

Yes, there's a lot of data.
But I was thinking in AMFPHP for that.
I think the alternatives are:
1) Adapting the Flex code that I need to a pure AS3 project (I'm not sure if 
this is possible in all the casses)
2) Using RSL's

Because I can't start my project with 200Kb, the size is a really big problem.
Can you (or someone) help me with some of the 2 options?
I have not experience in it, so I can't think in possible problems with those 
solutions (Flex->AS3 and RSL's), can you see the problems?

[flexcoders] Re: I don't know if I need Flex (please help me to decide)

Yes, that helps a lot.
I was searching and I found this:
http://www.logicalchaostheory.com/2008/02/10/remoteobject-for-flash-cs3/
I have not tested it yet, so I don't know if it has problems.
But what happens with applications like WebOrb? do you think faking the 
RemoteObject class will work?
Also, "Serialization and de-serialization on the server side", is solved by 
WebOrb, I think that's won't be my problem (or yes? :S)

I'm trying to download the open source of Flex, and I found this:
http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4
http://opensource.adobe.com/wiki/display/flexsdk/Downloads

I think I need the "Open Source Flex SDK", but what is inside "Adobe Add-ons 
for Open Source Flex SDK"?

AMFPHP works with flash also. You need to update the data yourself within

[flexcoders] Module-friendly modals

[Richard Rodseth]

Someone on the Mate forums advocated a way to treat a modal popup as a
state of a view, where the presentation model has a "modalShown"
property, and the view observes it using bindSetter.

This has the nice effect of avoiding the need to pass in
Application.application to createPopUp, but it's obviously quite a bit
more work to create the bubbling events and injections. And in the end
you typically want to center the popup over the whole application,
rather than some intermediate container.

So I find myself wondering if there is a cleaner way than
Application.application to refer to the root context. Follow the
DisplayObject.parent chain until it's null?

RE: [flexcoders] Re: I don't know if I need Flex (please help me to decide)

Consider also Adobe's ColdFusion.  I have found ColdFusion to be easier to

Re: [flexcoders] Re: Line Chart, I have a X value, how can I find the Y value?

[Brendan Meutzner]

Lol... yeah there's an easier way ;-)

It's been a long time, so I can't explain fully off the top of my head, but
check out the dataTransform object and specifically invertTransform(x,y)
which takes screen coordinates and returns the axis values at that point.
 You can look into a blog post I did many years ago which will contain all
the wisdom you need (I hope), although it's fairly involved and may have a
lot you're not interested in.

Here's the post, and source link.  Specifically check out
com.cnet.annotation.view.AnnotationDrawLayer
for the getChartCoordinates() method.  Additionally, Ely Greenfield created
a solution for easy charting translations... don't remember the name of the
package, but check out his blog (www.quietlyscheming.com).


http://www.visualconcepts.ca/clients/cnet/ChartAnnotation.html

Hope this helps... without the whooshing sound :-)
