[flexcoders] Re: Accessing a Basic Auth protected site from flex.
Thank you. This explains a lot. I had seen posts on how to do this but
nowhere did I
stumble on the info you provided. Specifically, that 9.0.115.0 was a version
that blocks
the Authorization header regardless of what you do. Guess what version I've
been
running? So, I will update to a more recent version and give this a try.
Unfortunately while this will work for some basic auth protected systems I have
to figure
out what to do about network devices I'm connecting to that can't have any
crossdomain
file added to them. For those I may just end up setting up a proxy using
something like
mod_proxy.
I will post the results after I try this out.

[flexcoders] mx:Image loading swf from URL not working consistently on OS X.
Hello, I have an application that runs on every Windows based browser I've tested so far and even on Mac OS X up to version 9.0.47 of the flash player plugin. Recently a security update to 9.0.115 on Mac has caused an app to break. I broke it down to a simple test case. mx:Application . . . mx:Canvas . . . mx:Image source=swfUrl / /mx:Canvas . . . /mx:Application . . . The first time the main app loads the SWF loaded by the mx:Image tag does the right thing. The swf is pulled from the web, it runs and works as desired. Subsequent refresh of the web page will not show the swf. The SWF being loaded by the mx:Image tag is only a simple short flash movie. The main application does in fact run but this loading swf doesn't show on subsequent loads of the page on OS X. I have a timer in the main application that governs the time the Image SWF is shown and then runs the main logic. The main logic always runs and works fine. Have any of you seen any behavior like this? One more note is that the source for the Image can be a SWF that is embedded in the main application. This ALWAYS works fine when specified. The only issue is loading the SWF over http and only after the first load following a cache clear (Safari and Firefox on Max OS X show the same behavior). The external swf is specified with a url parameter passed into the main app. If this parameter is not present the app loads the embedded swf for the splash. I run the app on Windows on IE, FF, and Safari and no problem. Any hints? Thanks in advance.
[flexcoders] Re: mx:Image loading swf from URL not working consistently on OS X.
I found a solution. This seemed to be caused by either the browser or flash player caching the movie being loaded. Why it wouldn't just run is beyond me. The solution I put in place is to append a query string with the date to the movie being loaded into the Image. This worked. Why did this pop up with the current release of the flash player? No idea. --- In flexcoders@yahoogroups.com, Alex Harui [EMAIL PROTECTED] wrote: Strip out your logic so it really is just an Image in an App and see if it does load.

[flexcoders] Correct way to load Flex SWF IF correct player version?
Hello, I am about ready to deploy a Flex application that users can add to web pages of their choice using an embed (or object) tag. I want to make sure that the client player version can play the Flex application. The following model is what I would like to use and I want to know if this is a model that would be advocated as a correct solution to this problem. 1) Client browser requests version check SWF. Parameters are passed to this SWF. 2) The SWF loads into the client's player and checks the version. 3) If the version is correct the SWF would load the Flex application into the player. 4) If the version is less than the required version I want to give the client the option to upgrade to the correct Flash player version. Is this an approach that can be made to work reliably assuming a base flash player version of 6 or is assumed? Thanks inadvance.
[flexcoders] Re: Correct way to load Flex SWF IF correct player version?
The embed and object tags are the most common methods I've seen for applications like the one I'm building which is one of the main reasons I want to use that approach. I intentionally built the application to require one and only one parameter. Any additional parameters are loaded in via XML along with other dynamic content. That said, is it possible to use a SWF built for a reasonably recent version of the flash player (let's say 6 or 7 and up) to: a) detect the correct version and load the intended Flex application. b) detect that the player needs to be upgraded to 9+ and prompt the user to update.

Why not provide a JavaScript file on your site that can be included (javascript src=http://...;) that does the check and document.write()'s the required HTML ? This also means if you ever need to add additional parameters you don't need to get everyone to update all their tags. Also, last time I checked, object/embed tags weren't the best way to embed SWFs - you should use a JavaScript based method because of the Eolas nonsense. -- Tom Chiverton Helping to enthusiastically compete proactive materials on: http://thefalken.livejournal.com This email is sent for and on behalf of Halliwells LLP.

[flexcoders] Re: Correct way to load Flex SWF IF correct player version?
FYI, Javascript is a non-starter for us. Sites like myspace block script tags so the best tool we have would be an embed or object tag and have a swf that can do what we need. Have any of you deployed a Flex application that can be embedded in other web pages that you do not own that do not allow anything but embed or object tags (i.e. myspace for example)? Believe me, I wish this were baked into the Flash player from day one where there was a way to specify a minimum version number and the player did the rest and prompted for the user to update.

[flexcoders] Re: What is the correct way to detect activation of a Canvas in a ViewStack?
It does need to be run each time this Canvas gains focus. The short
explanation is, one canvas has merchandise items available for sale.
An item is marked as in cart when it is added do prevent a user from
adding an item multiple times that is only allowed to be in the cart
once. The cart lives on another Canvas in the stack. A user could
choose to remove an item from the cart and then select that
merchandise Canvas again and the button needs to be reactivated and
have its label and style changed.
Therefore the only way I knew to make this happen within the Flex
model is to use a show event that triggered and caused the Canvas to
update itself.

[flexcoders] DataGrid, itemRenderer, button with custom image resizing
Hello, I have a datagrid I use to represent a shopping cart. One of the columns will contain a button used for deleting an item from the cart. The button is skinned with a custom graphic. I have been able to get the button into the column. I did this by subclassing Button in ActionScript, assigning a style to it representing the up, down, and over skin, and am able to process clicks and perform the required functionality. The problem I have is that the icon stretches to fill the column. I want the icon for the button to remain fixed size and not stretch. I have tried everything I can think of and am clearly missing something. Does this sound like the correct implementation approach? If so, can someone give me a pointer for how to solve this issue? If not, can someone suggest a better implementation for the item renderer to achieve the same functionality. Thanks in advance.

[flexcoders] Flex Number addition math bug?
I have an application that is showing me stange results from basic
addition. In short, I have a cart full of items that are all $0.99.
Each price is in a Number property of an object. The math is simple.
It is generating very odd results. If I start with:
var total:Number = 0;
var price:Number = 0.99;
then do:
total += price;
total += price;
total += price;
You would expect total to be equal to 2.97. I get 2.9699...
The next time I add price I get 3.96.
The following simple application illustrates the problem. Try it. Do
you see the same results? Am I doing something wrong or is there a
math bug? I can work around this but would REALLY like to understand
the root cause.
