[Flashcoders] ActionScript 2.0 TileList component?

[Kalani Bright]

Hi,

I'm trying to solve a specific problem (using AS 2.0).  I'm trying to avoid
some coding.
A DataGrid won't do what I want (to lay out the rows in tile formation).
I'm also using custom
CellRenderers.

Seems AS 3.0 has exactly what I need (the TileList) except for all the other
components I need which have gone missing.

Is anyone aware of a component which displays thing in a TileList way but
also has all the goodies of Flash's list based components (CellRenderers)
and usage of DataProviders?

Help? My vision is going black!

Mahalo,

Kalani

[Flashcoders] Flash Player | Plug-in vs ActiveX -- Same or Different?

[greg h]

Over in a thread on the ApolloCoders
list,
Marcel Panse asked:
is the firefox plugin different from the IE player.. or do
the plugins just point to the same player?

I am curious too.  Does anyone here know?

I always thought there was a separate plug-in for Mozilla/Firefox and an
ActiveX control for
IE.
And looking at this post by Tinoc Uro about the Flash Player build
processseems
to support that there are separate builds (on Win32:
NPSWF32.dll for Mozilla/Firefox, and Flash.ocx for IE).

But I just confirmed that IE, Firefox and Mozilla do intercommunicate by
running the Examples in the docs for
LocalConnectionand
SharedObject.
Meaning LocalConnections do communicate between SWFs running in different
host browsers, and SharedObjects are shared between SWFs running in
different host browsers.

So even if the plug-in and ActiveX control are different, as a practical
matter, from the perspective of Flash developers at runtime they act as if
they are the same?

btw ... As a possibly interesting side note, the Flex 3 version of the AS3
Language Reference for
LocalConnectionincludes
the following:
The communication can be:
...

  - Between content (SWF-based or HTML-based) in an AIR application and
  SWF content running in a browser

Any insights would be appreciated.

This, in itself, let all the air out of AIR for me.

When I saw how AIR could do such a great job of fusing SWF and HTML,  
I guess I thought it would have similar capability with PDF. Instead  
it seems more like PDF is bolted on to the side. It is always on top,  
uses the Reader controls, and has very limited connectivity to the  
rest of the app.


Acrobat remains one of the most important file formats, with the

If so, then no, I don't... the current pre-releases can invoke an installed 
Adobe Reader to display a PDF, but I don't recall anyone seeing a way to 
produce PDFs locally.

If you can handle a server connection then ColdFusion can produce PDF, that's 
the closest solution I see so far.

Re: [Flashcoders] (OT) fscommand and air

[elibol]

Something along the lines of fscommand("exec", "pdfOutput.exe source.html
target.pdf");

Or any other extension that might be useful for producing report documents
for our ROI/Value Calculator desktop products.

We are currently able to produce html reports for the desktop, but we cannot
produce pdf or ppt documents. Having these capabilities would add a lot of
value to our applications. It would additionally balance frequent technical
cases for using other OCX wrappers over AIR.

fscommand exec is the only way I could think of implementing this feature.
Is this command available in AIR? If not, why? Can we expect to see pdf and
ppt generation in subsequent versions?

On 7/25/07, John Dowdell <[EMAIL PROTECTED]> wrote:

"FSCommand" was originally for the plugin to communicate with its host
browser. Then later it was extended a bit to control properties of
Projectors. The current externalInterface communicates with the hosting
browser today.

But there isn't a hosting browser in AIR. What would you expect it to do,
what are you hoping to accomplish...?

Re: [Flashcoders] Hebrew input

That's the key point. If you look back over several posts of mine on this
list, you'll see that when using embedded fonts, you're in much more
control
than non-embedded. Without embedding, you're at the mercy of the browser
and
OS, and the result is that you really have no idea what will show up
(quite
aside from the question of whether your end-user will be able to see
anything at all).

Unfortunately, embedding means that you definitely *won't* get RTL for
free.
Fortunately, if you're working with Hebrew rather than Arabic, the RTL
algorithm is reasonably simple so you may find you can manage it by hand
(it's less simple if you're allowing Bidirectional text, but still
manageable). You could also try FlashRTL, which is pretty good but doesn't
include any solutions for input.

Re: [Flashcoders] AS3 Events

[Muzak]

Hi Ian,

In one of my previous posts I was gonna suggest a custom Event that holds the 
contextInfo stuff as well, but then decided not to.
Basically because I don't know what exactly this piece of the puzzle fits into.
What I mean is, there's several ways of doing what you want to do. Two of them 
I already mentioned.
- store them in B (Dictionary)
- pass them onto A (getter/setter)

Third would be to have class A dispatch a custom event which holds the 
contextInfo, but this also means you'll have to pass the 
contextInfo to A in the first place (in B) and since you wanted to avoid that, 
I didn't mention this solution earlier.

In Flex (AS3), the third option is what I use now, dispatching custom events.

For instance:


// pseudo code (I'm in a hurry, sorry)

class LoginEvent extends Event {

public static const LOGIN:String = "login";

public var data:UserVO;

function LoginEvent(type:String, vo:UserVO=null) {
super(type);
data = vo;
}

}

// somewhere in app
function loginUser() {
var vo:UserVO = new UserVO();
vo.name = "foo";
vo.password = "bar";
// create new event which holds user data
var evt:LoginEvent = new LoginEvent(LoginEvent.LOGIN, vo);
SystemEventManager.getInstance().dispatchEvent(evt):
}

// somewhere else in app -> some class that listens for LoginEvent.LOGIN
function loginHandler(event:LoginEvent):void {
trace(event.data.name);
trace(event.data.password);
}

regards,
Muzak

I'm looking to connect a projector to an Access db, both on CD.

Looks like Zinc will do this, but I'm curious if any folks with experience 
in the area could enlighten me:


1. Are there any client requirements? MDAC version? Do I have to make an 
ODBC connection?


2. What does Zinc mean when they say the recordset can be dumped "in a 
simple XML format"?


e.g. is there any control over the XML structure, or is it WYSIWYG?

Thanks.

[Flashcoders] Displaying Chinese character set via XML

[Marc Hoffman]

I cannot get a dynamic text field to display Chinese characters from 
XML. Results vary from question marks in the field, to "undefined," 
to blank. What should happen is that Flash derives elements from the 
XML and displays them in the textfield. I'm using XMLSA to parse the xml.


Another language (French) works fine. Anyone have a Chinese example 
that works? Here's what I've got so far:

   * TrueType font is SimSun.
   * XML is being saved as UTF-8 in TextPad and declares UTF-8 as 
the encoding language. Also tried this all using NotePad. Got both 
text editors to show the Chinese characters as the actual characters 
and also as boxes. Tried saving as UTF-8 and also as Big-Endian. I'm 
using CDATA around all text.

   * XML is being pasted from MS Word. Also tried pasting from Excel.
   * Flash textfield: Set for HTML. I've tried various combinations 
of embedding Chinese characters, including embedding ALL Chinese 
characters (lots of bytes!). I've also tried populating the text 
field with ALL the Chinese text, and using "Auto-fill" to embed those 
characters. I'm not using any bolding or italics.


I'm losing hair over this and would really appreciate either a 
working example (including the xml and flash files) or some more 
troubleshooting methods.


Thanks,
Marc

I should note everything works great in Firefox.  This is only

[Flashcoders] Audio Stuttering on CD

[Richard Mueller]

I have some audio slide presentations that I've created in Flash for the 
web that I need to put on CD.  I am using autorun to execute an index.html 
page and then from there, the user can select the various 
presentations.  But from CD, when I open the presentation, the audio 
stutters(loops the first second) and slides do not advance.

RE: [Flashcoders] AS3 Events

[Sunil Jolly]

Hi Ian,

Sorry, it's not very clear in all that garbled code.

If you make a new instance of B each time then only 1 request would be
made to each instance. The event could then be sent to the same listener
for each instance but with the appropriate parameter as part of the
(custom) event.

If you think about it, it's very similar to how Delegate works by
creating a "holding" area but now you have a (custom) event dispatched
which is fully typed. 

I suppose you have to decide if it's worth the extra time or not based
on what you're doing. :)

Hi Sunil,
   That won't work if multiple requests are filtering through the same
B - which is where the whole problem starts from. :-) Because request
2 overwrites the contextInfo written by request 1 - which is why both
Muzak (and I) suggested B has an internal list of contextInfos. But
that gets more tricky...

But thanks!

Well, XPath is just one way of searching through an XML document to get 
specific nodes. As you might guess from the package name, this 
particular implementation can be found at www.xfactorstudio.com . You 
can learn more about XPath itself at W3Schools, or from reading the 
official specification. Google will give you more links than I can, and 
faster.


If you're working with XML even a little, XPath is worth learning. It's 
like regular expressions -- a specialized little tool that can make very 
tedious things extremely easy.

The steps would be something like this:

1. get all the nodes which might contain the word (probably as an array)
2. loop through the array, getting the string from each text node
3. use String.strpos to see if the word is present.

Which step is giving you trouble? My code would look something like 
this:


import com.xfactorstudio.xml.xpath.*;

function findInXML(rootNode:XMLNode, target:String):Boolean
{
var nodeArray:Array = XPath.selectNodes(rootNode, "xpathQuery");

for (var i:Number = 0; i < nodeArray.length; i++)
{
   if (nodeArray[i].nodeValue.strpos(target) != -1)
   {
  return true;
   }
}
}

And there you go. The XPath query would be something like
"parentNode/childNode/text()".

[Flashcoders] Send mail from a remoting method?

[Dave Mennenoh]

Anyone know if it's possible to send an email with PHP from a remoting 
function in AMFPHP? I can't seem to get it working... the rest of the method 
works, the mail() function just does nothing - and it works in a test 
script. Just not in the remoting method. Do I need to call a sep php page 
for this, and not do it through remoting? It just makes it a pain since all 
my info is already in the remoting method.


thanks

Hi Ian,

I didn't fully understand your reply to Muzak's suggestion, but this is
based on that and seems to fit the bill.

Sorry it's a bit messy but you get the idea...

Are there still issues with this one?

Oh, and reading the link you supplied, the only concrete suggestion is
from Aral Balkan, who suggests (as someone did in an earlier thread)
that you subclass the Event class.

How would that help in my case? Any suggestions? To go back to my
original example, if you assume class A is a black box that fires an
event of class Event (Event.COMPLETE), we have no way (to the best of
my knowledge) to make class A produce subclasses of Event instead;
unless the suggestion is to subclass A to produce different events,
which (depending on A's implementation) could be very difficult.

Re: [Flashcoders] Searching within XML

[Ron Wheeler]

It is hardy much more work to parse the XML manually.
We did a complex search (find me all the things that a fireman might use 
for personal protection during an earthquake or what respirators are 
used by first responders or what headgear does the police marine unit 
wear) without XPath. Just travelled through the XML tree and applied the 
search criteria.
We used XML to pass the search criteria as well. Nice separation between 
the user interface (responsible for building the search criteria) and 
the search engine (responsible for applying the search criteria to the 
XML database)


It appears that this code uses XPath to find the subtree of interest and 
then navigates the subtree.
XPath certainly makes it clearer if the tree is complex with lots of 
sub-trees that are not involved in the search.

You get right to the root of the tree of interest.

[Flashcoders] RESOLVED: Flash 8 exception handling

[Alan MacDougall]

Alan MacDougall wrote:


This looks completely straightforward and identical to Java... but 
when I do it, it catches the generic error. Now, obviously an Error 
instance is getting caught, which means one is getting thrown, which 
means my InvalidPathFormatException IS being recognized as a subclass 
of Error! It's just not getting caught by the right block! And it's 
not a priority thing, because if I omit the catch block for e:Error, I 
don't catch anything at all (but I DO get debug output of the string 
"Error").


One of the comments for the relevant Live Doc solved my problem: you 
have to use the entire qualified class name in your catch statement.


try
{
   stuff();
}
catch (e:com.mydomain.package.ExceptionClass)
{
   trace(e.message);
}

This chapter from Colin Moock's book ( 
http://www.actionscript.org/resources/articles/603/1/Exceptions-and-Exception-Handling/Page1.html 
) appears to miss this vital piece of information... I guess he tested 
it on a version of Flash Player that didn't have that bug?

Its more effort/work I guess but it might pay off in the long run!
(Which is what clean code is all about isn't it?) :)

If you were doing a quick knock-out job then Delegate/Proxy might be the
solution for that situation though. ;)

Sunil,
   Yeah, that was my initial question. When I posted an AS3 version of
Delegate (to deal with this problem) a few months back, there seemed
to be general disapproval:
http://groups.google.com/group/flashcoders-storage/browse_thread/thread/2e96884b04d28f00/22eb09149a920a6e?lnk=gst&q=delegate+Ian&rnum=1#22eb09149a920a6e

I haven't had a chance to look deeply into it until now (with the
porting of the new framework) and I can't find an elegant alternative.

It didn't help that my original example used buttons, which are easy
to find alternative answers for! It's very different when dealing with
asynchronous loading or asynchronous animations...

So, yes - reasons for the original objections would be useful, too. :-)

(For info, my original blog post on this here:
http://wildwinter.blogspot.com/2007/04/come-back-delegate-all-is-forgiven.html
)

Cheers,

Hiya Muzak,
  Yes, just been trying that one out. But (sadly!) again it doesn't
hold water, as the contextInfos need to be in a hash/Dictionary, and
need to have a key. For the general solution, it can be very difficult
to find a unique key that can be recreated from the Event in the
callback.

  For example, in the loader example I gave, object A could be used as
the key (and recreated from Event.target). But not if A is a service
object that gets used for each B request (i.e. use the same A lots
instead of creating a new A each time). So what else could be used as
a key? The url - no, because multiple overlapping requests could be
issued to the same url (it has happened!).

  Tricky. A solution could be found for this instance - but not a
general pattern.

  So I think I'm left with my Callback.create(handler,arg1,arg2)
method (like old Delegate/Proxy), unless anyone has any better
suggestions.

[Flashcoders] Searching within XML

[Omar Fouad]

I am doing some application on flash that uses an XML file to store data...
This application has a search form. I understand how to get through the xml
by loops but i can't figure out how to get flash to know if this "word" is
included within the xml nodes or not... Any simple idea?

Regards

Well, alot depends on the context of the whole thing (the bigger picture).
If contextInfo isn't used/part of class A or B, it shouldn't even be there.

Then contextInfo should probably be a property of A or B.
IMO that doesn't break encapsulation but rather enforces it.


contextInfo is relevant to B, not A; and I agree, that doesn't break
encapsulation (it does if contextInfo is placed in A).

However, because there might be multiple outstanding requests through
B, B can't simply have a property called contextInfo (because each
request has a different contextInfo). It could conceivably have a
_map_ of contextInfos, keyed in some way to each request.

But this just seems like overkill, particularly when a simply
Delegate(handler,contextInfo) solves the problem and is a lot easier
to read.

I honestly can't understand why other people aren't tripping over this
situation; it seems an obvious problem in an environment like Flash,
where you have lots of asynchronous requests kicking around. I was
hoping there'd be a standard approach to the issue; it looks like
there isn't.
