Flex/CF vs xhtml/CF

Hi all, whilst I have kept one eye on flex I have never
ventured in.
I currently build and maintain a internal application,
consists of various functions such as customer data management,
sales data management etc etc..
my question is, as a complete flex newbie, what is the
benefit of me using flex (and coldfusion) or as i currently do,
html web pages and coldfusion...?
Many thanks in advance

It greatly depends on your intended purpose or “Use
Case” of your application really. So this is not something
simple to answer without knowing that. But the biggest reason I
chose Flex over traditional xHTML (Web 1.5 :) technologies is if
the application I am building needs to act and function more like a
desktop application rather then a WebSite. Think statefull vs.
stateless.
So for intranet applications, command and control
applications, generally anything that requires a rich UI and there
is no need for extensive SEO within the application. I would use
Flex.
For simple information sites with little user interactivity,
other then navigation, where a majority of the application is
simple text, (wiki's, pamphlet sites, ect...) or when I need to
make sure that the site is indexable by the major search engines
(not so much a problem anymore) then I use xHTML.
More and more however I find less and less of a reason to
drop back to any form of xHTML and am finding that just about
everything I would even need I can accomplish in Flex. Now that
Google and Yahoo are introspecting and indexing SWF files the SEO
is less of a problem (though not perfect yet).

Can someone please tell me why my flex swf isnt appearing in firefox?

Like the title says, could someone possibly explain to me what im doing wrong with embedding this swf? **My code works fine in chrome**...But doesn't appear in FireFox, and it look compacted in IE, like its only set to a 5% height or something.
All I want to do is have the swf scale to 80% width(then i use the margin:0 auto; to center it), then 75% height. Theres a header, small ad at the top, and a footer at the bottom. All while being compatable with Chrome, FF, IE.
Incase possibly this matters..in my Flex Project I set the swf height and width to 100%. I figured since it's being embeded inside the `.mainContainer` div, the swf would then assume its parent(mainContainer)'s width and height wich is set to width:80% and height:75%. **And it does it chrome just fine** but like i said above the swf doesn't appear in FF. I thought maybe i should note this incase it's necessary information to solve this bug.
I didn't think this would be too hard but I can't seem to get the swf to load in FF. I'm seeing the swf making connects to some netConnections and stuff like its there, i just cant see anything.
-What am i doing wrong?
-Is there a better way I should be implementing the swf?
-How can i figure out whats wrong on my own in the future?
(im so used to working in Flash builder on flash projects, the debugging is so simple, informative, and easy to use. With only having access to "inspector" in chrome which never spits out any useful information I feel like im coding in the dark compared to using eclipse)
**EDIT:**
1 more thing I should mention. Pretty much the entire "embed" code provided here was auto generated by Flash Builder. I created .mainContainer around the "embed" code and all the extra divs around it... my header, footer,ect. Without any of my extra content, the swf appears just fine like you would expect it in firefox. SO my point in saying this is i do not think its **literally** the embed code. Because that embed code works in FF. It's just how im implemented my header, and div around this flash content that seems to break the code in FF for some reason.

Thanks to those of you who have responded. It is just frustrating because I absolutely love this phone. I just was shocked to see these ever changing colored vertical lines and sometimes just light grayish stripes throughout my screen. They come and go. Constantly changing, sometimes disappearing and then showing up again in a different app or simply when I pick up my phone after leaving it sit. The problem is where to start? I'm thinking straight to the nearest Apple Store on Monday morning.

Completely different AMF request packets for same remote service call from Flex to PHP using ZendAMF

I was trying to debug why one of the remote-services in our Flex application was failing randomly. What I found was interesting. Completely different AMF request packets were sent for same remote service call from Flex to PHP.
When the service call succeeds the AMF request packet looks like the following:
POST /video/flex/bin-debug/gateway.php HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.15) Gecko/20110303 Firefox/3.6.15

And when the service fails the AMF request packet looks like this:

operation = "getMemberFromEvent"
source = "MembereventService"
timestamp = 0
timeToLive = 0
Also, following is the error message on Flex when the service fails:
{Fault code=Channel.Call.Failed, Fault string=error, Fault detail=NetConnection.Call.Failed: HTTP: Failed, Destination=MembereventService}
We are using Swiz as the micro-architecture for Flex development and Zend AMF for remoting between Flex and PHP.
Any ideas what is wrong here, what is causing Flex to send different request packets for the same service & what I can do to fix it?

Hi, I know that your post is almost 5 years ago, but have you found the solution to this issue?
Thanks.

people complaining about problems installing an office over another office are (dare i say it) stupid. it makes absolutely no sense installing one over the trial version. just uninstall the trial and you'll be fine. every single time.
as for problem with uninstalling mcafee (or any other antivirus, for that matter, just download the uninstaller from the software company e.g. http://service.mcafee.com/FAQDocument.aspx?id=TS100507 for mcafee.
that said i believe you get to choose if you want mcafee and/or office when you go through the inital boot, the "on-screen instructions"
you can slow down the odd via power manager
and thanks for the tips on changing the reg to have the user profiles somewhere else!

File Upload using Flex/ColdFusion. 2044 error

I am looking for a little more clarity around the file upload using Flex and Cold Fusion. When I run this using my server I get Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.
I did create a regular cfform and had it use my ColdFusion upload form and that worked fine, so I feel good about the upload form. I am starting to think there is a permission error with the Flash Player writing to the folder. When this is ran, it will show the file being 100% loaded but the complete event is never triggered. I put alerts to see where it hits and 100 does show at the same time as my error message. The complete alert never shows. I also put an alert in my cfm page and it never reaches that page to hit it. Whether I use an absolute URL or relative path. I have also tried the urlrequestmethod.post and nothing changed. Thanks in advance. BTW. I am using Flex 3.

Presumably you need to add a result handler to your request.

I will thank you for insight!

Just create a Flex component like any other. Here is information from the livedocs on creating Flex Components
http://livedocs.adobe.com/flex/3/html/help.html?content=ascomponents_advanced_3.html
To create something that mimics an h1 tag, you might look into a modified Label or Text class.
Honestly, I'm unsure why you'd want to try to reimplement xhtml tags in ActionScript 3.

Can Flex do dynamic UI like AJAX?

With CGI or AJAX apps, if I want a checkbox for each of a
number of items returned by the server, I can just have the server
spit out a bunch of checkbox HTML elements, then set them as the
innerHTML for some div.
Since Flex is compiled, it doesn't seem like this is
possible. Is there a way to have any number of checkboxes
dynamically generated based on output from a server?

If your HTML is valid XHTML, you should be able to use e4x to
walk the tree
and display equivalent items. But since you have it working,
why not just
leave it alone?

Problem with DOCTYPE tag in the index.html for flex file

When I have the following !DOCTYPE tag in the index.html file I use to load the flex swf file(s) both FireFox and Orical browsers both become horizontally shortened. When the tag removed everything works fine. Given that the !DOCTYPE tag is necessary for good html I'd really like to know what's going on.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Good info on that site about HTML, unfortunatly it had nothing new for me. I did double check and everything and I was doing things the way they recomend.
I'm really bothered that this is happening. The DOCTYPE tag should be used and it should not have this effect when added to the HTML generated by the Flex Builder. Additionally the new Flash Builder does have the DOCTYPE tag in its generated HTML and this is very worrisome.

I have a thesis project that must involve Flex

Hey guys, I'm trying to think of a useful Flex (possibly AIR deployed) application idea for a thesis project I'm doing in school this year. Problem is we have to have and present our idea prior to having any classes on Flex yet which makes it somewhat hard to think of the possibilities. We've had one intro class and I got to play with it and get a nice idea of it during an internship in England over the summer.
So far I have one decent vague idea and one very very vague ideas and I'm just looking for some insight as to if my ideas are even possible/worth it and any ideas you may have that I could try!
My first idea is to build an 'image gallery builder'. So an app for someone who has no knowledge or experience in web design and wants say an image gallery on their website.
For eg: A hardware store owner has a website and would like customers to able to easily navigate the store’s inventory in an image gallery displaying images of products for sale.
So my app would allow him to use a WYSIWYG interface that allows him to manipulate all the properties of a gallery with some sort of completely dynamic changeable base gallery layout. So with all sorts of visual buttons and such the user can change whatever feature of the gallery they would like. Thumb nail sizes, carousel types, headers, content text, colors, content layout etc. And everything they manipulate they can see a it change on the fly.
A lot of other gallery builders I see out there are very ugly and have very minimal options if you know what I mean.
What do you think? Is this something incredibly hard to do? does it make sense? That's as far as I've thought it with my minimal knowledge in Flex as of now.
My other ideas was do something with Flex and the Google maps SDK/API to create an interactive map to visualize geographically-based data that user can work with sorta thing.....haven't really thought that one much further...
Do you guys have any neat Flex application ideas I can consider?
And of course using Flex I have a good amount of knowledge (for a third year student) in XHTML,CSS,JS,PHP,MySQL,AS3.0

No. Are you saving the project as a disk image rather than burning directly to disk from iDVD? If not then that's what I suggest you do. That will separate the encoding process from the burn process to save time and disks if the encoding is bad. It also lets you burn a second or third disk without having to encode again.

Multiple JavaScript errors on Flex LiveDocs pages

don't work properly with Opera 8.5 and Opera 9 browsers.
Most annoying being Show/Hide Inherited... links not working

So get this. After disabling, uninstalling, reinstalling both the extensions and Dreamweaver. Even deleted some new printer drivers because that was the only other thing that had changed, it came down to this...the DOCTYPE!
Not exactly sure why, but the DOCTYPE on my page had changed from
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
to
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN">
That's what broke the extension. Apparently ADDT needs "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"! As soon as I added it back in, it worked without any issues.
Thanks for the help though!

Begginer Flex Apps for browser Questions:

Begginer Flex Apps for browser Questions:
To change Dim in Flex App I must change file in address bar of browser, in other words create another page?
Usually Flex Web sites come in only one file or many [upper 10?]?
Scrolled Area in Flex how called [I mean like XHTML DIV Scrolled area?
I book Flex 4: vol. I , Tranning from the Source, from Adobe press, covered:
Scrolled Areas
email components
publish to live server
if not, then all these covered in vol.II?

to change the dimension of your flash window inside the browser you can use javascript... or you can have your flash-element in full size of the browser window and handle the resizing flash-intern, so you do not need an extra page for that. Just take a look at the HTML-Code and ask again if you are not that skilled with HTML/JavaScript.
usual you have only one SWF.
You can use the spark Scroller (see http://blog.flexexamples.com/2009/05/01/creating-a-scrolling-spark-panel-container-in-flex -gumbo/ for example)
Sorry, I don't know, but I can give you some hints:
for scrolling you can use Scroller
I don't know, what you mean by e-mail but you can use javascript to create a "mailto:"-link (see http://flexonblog.wordpress.com/2007/12/18/mailing-in-flex-using-javascript-function-mailt o/ )
the easiest way to deploy you just have to copy your swf and html-files from your flex-project to a web-server.

Browser scrollbar if needed - Flex 4

I'm working on a flex project and I'm trying to resize my application based on the content being displayed in the current state. I'd like the wrapper to resize in the browser so that the browser's scroll bar appears if needed, which would be dependent on the user screen size.
I believe this needs to be done using Javascript but I haven't been able to find any good resources or examples.
I'd really appreciate any input.

you just need the other way to embed the swf file..
try this
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
     <head>
