[flexcoders] Text/Font with border on characters?
Hi, I want to overlay text so that it can be read regardless of the background colour (without putting a background behind the text itself). So basically I want the text to have a border around each character with a different colour - white with black surround for example. Any ideas how I'd approach this? Will it require a particular font or can I handle it from within Flex? Thanks in advance Bill

[flexcoders] Re: still having trouble with breakpoints
I'll just echo that I see the same thing (again only in .as files included by script tags).

[flexcoders] Datagrid with bound dataProvider not updating.
Hi, I have a datagrid with the dataProvider bound to an array of objects. If I remove one of the items from the array the datagrid doesn't update to reflect this. Debugging and looking at the dataProvider's length it has updated, but that's not what's displayed. I've tried using validateNow() but that doesn't work. If I click on one of the column headers it updates. Currently I'm having to explicitly set the dataProvider in code, but then I lose the binding. Any suggestions? Thanks Bill
[flexcoders] Re: VideoDisplay volume problem
Have you looked at the reply in this thread? Anyway, here's another thread on same: http://tech.groups.yahoo.com/group/flexcoders/message/75277 If you don't want to subclass, another trick that might help is setting the volume to some random value before setting it to the value you want. (I think if the volume's value isn't changing it will be ignored, but that it has to be set after the video is loaded, so if you keep setting it after loading to what it was set to before (but ignored), it won't change. I'm not sure I understood that sentence, but I hope it helps! :- ) ) --- In flexcoders@yahoogroups.com, Paul DeCoursey [EMAIL PROTECTED] wrote: I am having an issue with a VideoDisplay.

Still crashing Internet Explorer 7. Surely this is a pretty major

Also while garbage collection usually kicks in a drops the memory

rise to a much higher level (i.e. from 4.5 to 29.5 million bytes)

[flexcoders] Re: videoDisplay.volume not working
Hi, I started by doing a quick check and then got quite involved in this. Turns out there's a fairly simple solution (I think). There is a bug whereby if you set the volume before the video is loaded it doesn't get set properly I think if you call vidDisplay.load(); before setting vidDisplay.volume = 0; it should work. Bizarrely if you just use vidDisplay.play() and set the volume on the VideoEvent.READY event it doesn't work though. I've also had problems with the vidDisplay object forgetting its volume setting if you change the video source and reload (even though the it still reports it's volume as 0). It defaults back to 0.75. Hope that helps Bill --- In flexcoders@yahoogroups.com, yiÄit boyar [EMAIL PROTECTED] wrote: hi; i'm setting the volume property of a videoDisplay to 0.0 but when the video is loaded; there comes sound... is this property not working or is there a crack for this (like flex 1.5 useHandCursor crack) or what am i making wrong ? thnks.

With the exact code I included I had the following behaviour: initial memory: ~4.5 MB for a few hours: the memory would cycle up to about 6.5 MB before garbage collection would kick in and it would go back down to ~4.5MB The next day: Memory had hit a max of 29.5MB and even using the hack to run garbage collection wouldn't bring it below 26MB Is there a fault in my code, is this a bug or is this just the normal behaviour for an application?

[flexcoders] Events not firing from swf imported with SwfLoader
Hi, I'm not a flash expert so you'll have to bear with me on this. I'm not creating the swf's myself. I've recieved animations in swf's before and used them in image controls and they work fine. (movie clips generated in Flash MX 2004) If however the swf has a button on it (just an animation which plays on the rollover and snaps back to first frame on rollout) no events get fired from it when it's embeded into my image control. I'm assuming that the button in the swf is catching all mouse events and not passing them on. Does anybody know if this is the expected behaviour or if there's an easy way around it? As it stands I guess I'll need to handle switching to an animation on the rollover event within Flex2. Thanks in advance Bill P.S. I saw this, but it seems like overkill for what I want. http://www.jessewarden.com/archives/2006/08/flash_9_button.html

The idea is the have a toolbar where as I scroll over the images are
zoomed (ala Mac toolbar I think).
I find that when I move the mouse slowly across the images it behaves
as expected. However if I move the mouse more quickly all the images
end up getting zoomed.
I'm pretty sure I know the reason why, but I'm not sure what the best
solution is. I'm guessing the the different zoomInstances are getting
mixed up as I scroll over the different images, but what's the best
way to keep track of them? I don't want to have a different
zoomEffect for each image as I want this to be scaleable.

[flexcoders] VideoDisplay bug?! How to extend to change a private variable?
Hi,
I would normally spend more time trying to work this out first, but
I'm under a bit of pressure... There appears to be a bug in the
VideoDisplay code.
vid.close() = within the videoDisplay a private variable called
closeCalled is set to true.
vid.play() = the closeCalled variable is set to be false in the play
function.
Fine, but:
vid.close() = closeCalled=true
vid.load() = loadVideo()
vid.play() = if (closeCalled==true) {loadVideo()}
So if you load in the video this variable is not reset to false. This
means that the video gets loaded twice; once when the video is loaded
and once when the video is played...
Anyway, all this is besides the point... I just want to know how to
get around this. I've tried this:
package libraries.utility
{
import mx.controls.VideoDisplay;
public class NewVideoDisplay extends VideoDisplay
{
//private var closeCalled:Boolean = false;

function.
Fine, but:
vid.close() = closeCalled=true
vid.load() = loadVideo()
vid.play() = if (closeCalled==true) {loadVideo()}
So if you load in the video this variable is not reset to false.
This
means that the video gets loaded twice; once when the video is
loaded
and once when the video is played...
Anyway, all this is besides the point... I just want to know how to
get around this. I've tried this:
package libraries.utility
{
import mx.controls.VideoDisplay;
public class NewVideoDisplay extends VideoDisplay
{
//private var closeCalled:Boolean = false;
public function NewVideoDisplay()

}
override public function load():void

[flexcoders] Re: VideoDisplay bug?! How to extend to change a private variable?
That did the trick thanks.
For when I get a chance I should really log a bug... anyone got the
url for that handy?
For anyone else with this problem, so long as you know you'll be
ALWAYS calling load() before play(), having done a close() this will
do the job:
package libraries.utility
{
import mx.controls.VideoDisplay;
import mx.core.mx_internal;
use namespace mx_internal;
public class NewVideoDisplay extends VideoDisplay
{
public function NewVideoDisplay()
{
super();
}
override public function close():void
{
//the real close sets a variable closeCalled
//which causes the next video to be loaded
after
//both load() and play().
//because we always load before playing we
can avoid
//setting this variable..
mx_internal::videoPlayer.close()
}
}
}

mx_internal is easy to access because it's just a namespace.
Simply import mx.core.mx_internal. After the imports type the line:
use namespace mx_internal;
There should be a complete discussion if you just search through
the mailing
list archives for 'mx_internal' specifically or you can just read
up on
namespaces in general in the docs.
HOWEVER, mx_internal is not documented or stable. If you use it
and an
update to the framework is released, there is no guarantee that the
update
will not break your code. Use at your own risk.

[flexcoders] Re: VideoDisplay.complete event doesn't get called when a video ends
Well you're not crazy, but I've no solution I'm afraid:
http://tech.groups.yahoo.com/group/flexcomponents/message/1549
I'd imagine it's something to do with how the flv is encoded? You
could try catching a state change event when the video stops playing
at the end, but I haven't tried that myself...
Good luck.

[flexcoders] Loading Image into BitmapData
Hi, I have what I hope is a pretty simple problem, but I'm not sure how to do it. I want to load in an image file (png or whatever) from a url and store it locally in a BitmapData Object. I suspect I need to use the Loader class, but I'm not sure how to get it out of this and into a BitmapData Object. Any tips appreciated! P.S. I know I could probably load it into a UIComponent and then draw it onto the BitmapData Object, but I'd rather avoid that if possible.
[flexcoders] Re: Cross domain confusion
I don't really have a solution, but a suggestion as to why it might be working locally. If you created the project in Flex Builder it will add the source location to a trust file: Documents and Settings\$UserName$\Application Data\Macromedia\Flash Player\#Security\FlashPlayerTrust\flexbuilder.cfg (for my setup anyway) This will override any sandbox issues when you run locally and possibly hide whatever security issue you're encountering when you deploy.

This works fine most of the time (just myVideoDisplay.totalTime)... However, for older flv files (before 1.1) this metadata is not included. If you're not streaming them from FMS, you can also load the entire FLV into a ByteArray and parse the timestamps from the FLV tags for yourself using a bit of AS3 ByteArray magic. Provided there's nothing strange about your FLV, the timestamp on the last tag should be your duration. I recently ended up having to do exactly this to diagnose a particularly pestilent bug where some of my FLVs were reporting patently wrong durations as a result of corrupt tag timestamps. You can get the FLV file format documentation from Adobe here: http://www.adobe.com/licensing/developer/ If you go this route, watch out for the timestamp byte order, it's a 32-bit unsigned integer, but is formatted as a big-endian UI32 followed by a most significant UI8 rather than the typical order expected by the built-in readUnsignedInt() method.

[flexcoders] Getting duration of FLV 1.0 videos
Hi,
I want to be able to get the duration of any flv file using the
videoDisplay object. This works fine most of the time (just
myVideoDisplay.totalTime)... However, for older flv files (before
1.1) this metadata is not included.
Looking at the code in VideoDisplay.as:
/**
* Total length of the media, in seconds.
* For FLV 1.0 video files, you manually set this property.
* For FLV 1.1 and later, the control calculates this value
* automatically.
*/
public function get totalTime():Number
{
if (!isNaN(_totalTime))
// totalTime was set manually, return the
// same value.
return _totalTime;
else
return videoPlayer != null ?
videoPlayer.totalTime : NaN;
}
But because I'm loading in different flv's dynamically I can't set
the totalTime manually, or more to the point I don't know what the
totalTime is to set it. Does anyone have any ideas for how I could go
about this? I've seen tools that will inject the metadata into the
flv, but I don't want to directly manipulate the flv itself.
Thanks in advance

[flexcoders] Video not showing in VideoDisplay... sometimes...
Hi, I'm wondering if anyone else has encountered this problem (or better still resolved it)... I have a VideoDisplay object which I load with a source flv. All fine. However, on some occasions the video doesn't display. I've set the backcolor of the VideoDisplay to red, to make sure it's nothing else appearing on top. I'm viewing the swf in IE7. Sometimes when I hit refresh the video will appear, sometimes not. The audio still plays and it still returns video duration and fires events etc. I can't seem to pin down any reason for this behaviour. Any ideas anyone? Thanks in advance. Bill
