Having this new problem with flash builder where I run a debug flashplayer, close out the flash and it doesn't always kill the process. Sometimes it does sometimes it doesn't, leaving me, after a while, having 10 or more flashplayer tabs on windows still open. I try to close them using the task manager with no luck.
This hasn't always happened, anyone experience this as well or know how to fix it?
Browser projects or Adobe AIR Projects? I've never seen this in Web projects. But, in Adobe AIR projects, when this occurs I usually can't launch a new debug session until I force quit.
I browser based, does your browser close when you terminate the debug session? If not, try to shut down the browser manually before launching a new debug session.
I'm sorry I don't have specific answers. I you expand on your Operating System, browser choice, and version of Flash Player it may help others.

I am facing one weird problem. In my flex application, there is one
grid on click of each grid item, it will dispatch one event and show
the details. As usual am changing the state of the component to
achieve this. But this is working perfectly in my machine, but from my
client side it is not working. Only difference am seeing is the
difference in flash player version. The FP version am having here is
10,0,45,2 but the onsite is having the latest version : 10.1.102.64.
Will this cause any problem in the behaviour of the flex application?
Am quite confused here, because I have no rights to change the player
version in my machine.
Do anyone have face the same problem like this. Or can anyone help me
with the main difference between these two versions.
Thanks in advance for your help.
Cheers,
Anoop
Most behavioral differences between flex applications are due to different flex SDKs being used during compilation (for instance, is your client viewing the binary-exact copy of the .swf file that you are running) or browsers with different plug-in APIs (the way they handle 500 errors for instance). If you think it's a flash player version issue (they are probably rare since they run regression tests across player builds so that flash swf files from eons ago run fine), you can certainly upgrade to that player build and see for yourself.
Are you also able to rule-out any connectivity issues such as firewalls or proxy servers?
While the item is clicked what are you using you using to get the selected item - event.target.selecteditem or event.currentTaget.selecteditem ? Try to change from target to currentTarget or vice-versa,it might work in both the machines.
How can I shut off the windows sound from an ASP.NET page.
Thanks.
Why on earth would a browser let you shut down the whole OS sound? Leave my sound alone!
Even if your on a desktop app, still, leave my sound alone!
The only way I can think of doing that would be through an unsecure plug-in or ActiveX control.
Also, doing so is just wrong in any case. Navigating to a web-page doesn't imply permission to change system-wide parameters.
Users of my Flex application report that sometimes the application is freezed when the browser window is minimized or they select another active tab over it. In this suspended state, the application receives no CPU share and all network connections it uses are closed. When the browser window is restored, the application is resumed. This happened with Safari 5 on Mac OS Leopard, with both Flash player 10.0 and 10.1. I searched a lot but I could not find any information about such behavior.
This behavior is not reproducible on each Mac with Safari, so my questions are:
Under which circumstances this may happen?
Is it possible entering in suspended state to be prevented and how?
Is it possible for the Flex application to be notified about going into sleep mode and wake up back?
This is a Safari thing and is by design. Newer versions of Safari suspend flash content that is not in the foreground tab (not sure when this started, version 4?) For instance, if you have multiple tabs open, each with a youtube video playing and you go back and forth between the tabs, only one of the videos will be playing at a time. To answer your specific questions:
This will happen to any flash content that is in a background tab (not sure about the minimized state.)
Not aware of a means of disabling this behavior.
You may want to dig around in the Safari documentation to see if there is some sort of JavaScript event that you can grab onto, but I don't think you are likely to have success there.
Good luck.
Are your users using Flash Player 10.1 ? As part of the performance improvements in 10.1; I believe an application in a minimized state will get throttled in order to use less system resources / battery power.
I don't think there is any way to prevent this; and no APIs exposed that relate to this.
Other people I've spoken to have had issues with using local connections between minimized apps and active apps. I'd bet there is already a bug in the bug base on that.
Wrt the following above:

You may want to check out if Silverline from Librato can help you control how much and which applications get what system resources (CPU, memory, Disk and Network IO) with dynamic control based on application demand. If the above issue is a feature of flash - then obviously it may not help. But if you are trying to say run multiple applications / processes and would like to control who gets how much system resources (dynamically) then you could try Silverline - it does not require any changes to OS or app. http://silverline.librato.com
I've got a flex-based swf, which is loading an AS 2-based swf and then, negotiating further activity via a LocalConnection.
From time to time, the AS 2-swf can request that the flex-based swf load a movie.
I've arranged this via on(release){} functions.
The AS 2-swf, I'm making in Swish Max. In Swish, when i set the on (release) on a text field, (to invoke .send() on my localconnection), it works splendidly. However, when I attempt to perform the same calls for an on(release) attached to a movieclip, it actually causes the Flash player, and even the browser plugin to crash.
In fact, the browser (IE) crashes as well.
I checked the debug trace that ie asked me to send to microsoft at the last IE crash, and i noticed a StackOverflow exception embedded deep in the trace, but I couldn't determine its source.
Can you help me understand what's going on here?
Are you having more than one LocalConnection connect to the same channel? This will cause the browser to crash.
Are you sending lots of requests at the same time, this will make it crash, and some browsers are more sensitive for those things than other.
This earlier post might have some helpful tips for you.
That's a wrong way to debug your application. Use your Flex Builder's debugging tool instead. You tend to lay blame on LocalConnection as it is the most complex part of the operation, when it could just as easily be an infinite loop.
You don't seem to be using the right tools either. I'd trust FF's FireBug over IE's dump. Besides, we'll need to see some more code before we can accurately tell you what's wrong.
Are you sure the crash is not only in your computer? Try running the FlashUtil??.exe at \WINDOWS\system32\Macromed\Flash\ to fix/update the Flash installaction. There are some known issues that corrupt Flash installation so it become unstable when using some objects.
This problem is beginning to annoy.
After my machine (Vista Ultimate) has been up for a while, running my ASP.NET web site project for debugging in VS2008 results in Internet Explorer "hanging". It doesn't seem to get past the network access stage, you know when it says "Loading web site", or "Waiting for".
I've attached a screenshot of IE. Note the status bar. It stays like that forever. I have to restart it and cross my fingers for it to work the next time. Invariably, it doesn't.
This happened with IE7 and IE8.
I am using the ASP.NET Web Development Server/Cassini. I have tried restarting this each time which seemed ot have got it, but then not so any more.
I'm up to date on patches.

So thankfully Microsoft have finally released Security Essentials.
This meant I could de-install AVG (Free and paid-for versions) from my machine.
Hey presto, it works!
I would check the following
1) that your not starting IE against the webserver againt the wrong port, if your using the development IIS then it changes ports at times. That combined with you setting up the browser to launch against a the old port could create this problem.
2) Stop the local IIS and restart it (Again make sure your pointing towards the correct port)
3) Make sure you dont have any hung IE in task manager ( this happens to me sometimes ). Basiclly you have a IE in task manager that uses less then 1mb of ram and does not show on the taskbar, if thats the case kill them.
This doesn't sound, strictly speaking, like a hang. Can that tab/other tabs be navigated to other sites? Is your machine configured to use a proxy?
Is the request actually sent? Using Fiddler2 from www.fiddler2.com with the URL http://ipv4.fiddler:56125/ will show you, and help determine where in IE the problem might be.
I just had a similar problem that took about a week to unravel. Using AVG 9 Business Edition.
I'm on a Windows 7 machine with Visual Studio 2010 SP1, debugging ASP.NET sites running in IIS, with the same "hang" behavior you're seeing. Disabling LinkScanner and Online Shield in AVG fixed the problem.
