Flash Screen

I am looking to replicate the flash screen alert option as found in the System Prefs > Universal Access "Hearing" pane but can't figure it out. I did find a script that will press the keyboard combo to invert the colors and back...
tell application "System Events" to repeat 2 times
key code 28 using {command down, control down, option down}
delay 0
end repeat
...but that's not the effect I'm looking for. Any ideas? I did also find a cocoa command called FlashMenuBar ( http://cocoadev.com/index.pl?FlashScreen ) but I'm not sure if this is something that can be called via Applescript.
Any ideas? I don't want to UI script the pref pane to click the flash screen button. I'd like it to be a standalone app.
Thanks,
Matt

Oops.
The error message means Perl compilation failed because the specified Perl module Mac::Menus could not be found...
The posted Perl code works fine with MacPerl 5.6.1r2 under OS9.1. However, it seems it won't work under OSX.
(The Perl code simply invokes MacOS's Toolbox function 'FlashMenuBar(0)' twice in sequence, as explained in:
Toolbox Essentials >...> FlashMenuBar
or in Carbon Menu Manager Reference (pp. 52-53 of pdf):
MenuManager/menu_managerref.pdf
Menu_Manager/index.html
As far as I've searched briefly, this route via Perl (currently) won't lead you to the goal under OSX. Although there exists a Mac::Carbon module in CPAN, Menu Manager routines seem not implemented (yet).

Can we show flash screen over the loaded HTML5 page in StageWebView for IOS?

Hi Guys,
I want to show flash screen(let say abc.mxml) over loaded HTML5 page in StageWebView. But unable to show it. Even I want to interact with both pages ( flash and HTML5) bidirectionally.
Can anyone help me out of this StageWebView issue?
Thanks,
Mamta

Okay. I guess it's not possible?
Seems like the closest way to get there would be the UIwebview Native Extension. But the examples on the website are pretty vague as to it's use. (at least for a non-C coder like myself)
Anybody use that particular ANE? Anyone? Bueller? Bueller?
Again, just need to set a simple property here...

Flashing screen OS X 10.8.3 (12D78)

I am sad to say the audio stutter issue that seemed to have been solved a few updates ago on my 2011 imac27' i7 has now been replaced by a new issue, a flashing screen..goes red or pink or orange then lines appear and then a white screen. Have to reboot. It did it a couple of times today since the (12d78). initially i thought id done a mouse move click to quickly and froze the machine (rare) but I noticed when trying to play 'quake live' on safari (a flash plug in type browser game) that almost immediately the screen would break up. Ive never seen this before and can only assume the update is the reason. Same as the audio stutter was. Something to do with the graphic card and 0sx? no idea. I have the AMD Radeon HD 6970M 1024 MB.
Im not aware of any trauma to the computer or anything other than the update. I have updated 10.8.3 quite a few times since i was given the preview beta updates.
Any ideas?

Hi, so, this is fierce. I cant work or play. My imac 2011 27i7 is destroyed the only thing that has happened i know of is i updated appleseed most recent software update. The last or or so updates worked fine the machine was stable and working brilliantly since the audio stutter was fixed.
Ive not installed anything recently either that may have added some new conflict. Yesterday using my fresh internet recovery of lion(imac came with lion) the machine stayed on long enough to get some important files out.
That was lucky because since that short time of semi function ive not been able to get as far as log in on start up before i am looking at a grey screen no apple logo or a blue screen with vertical lines. Or a black screen occaisionally with an white line across the top. This on any start up option . Sometimes i have got as far as seeing the hardisk start up options but it crashes if i try any of the options.
Today i got an email from appleseed mac saying thanks for participating there will be no more updates. Great!! Also Yesterday i was told that if i send my machine in for repair under my applecare and the fault is not hardware inside the mac i will be charged. So with problem looking software related i've a bad dilemma here. Days going by i cant work.
Also i was told my entire hardrive may need to be wiped. Thats all my apps and so on.
Im kicking myself for installing that last update.

How to stop Flash Screen?

Hello!!
I have a JSP page which has iFrame.
<iframe src="test.jsp" name="printframe" width="0%" height="0%" onLoad="abc();" > </iframe>I am generating PDF content in the iFrame and I am able to do that successfully.
But the problem is, whenever I generate PDF content in page, Flash Screen of Adobe Acrobat Reader appears.
How to stop that Flash Screen?

You write a nice letter to Adobe and you say:
"Please, would you remove your splash screen so that when I load my PDF file, the user doesn't know it's really using your software. I realize that you provide this PDF reader software free of charge to anyone who wants it, and that I have no right to ask you to hide your identity from the users of said software, but please please please please please?!?"
I'm sure they'll listen and release a new version just for you.

In other words, you can't, and you shouldn't be able to so just forget about it. It only shows the first time a PDF file is loaded in the browser session anyway.

"Flashing" Screen as if a photo is being taken???

I am using Snow Leopard 10.6.8 there are a few issues. . .
Since installing it a few weeks ago I get this strange single “flashing” of the screen every few minutes, almost as if someone is taking a photo. A bit creepy, actually.
I covered the camera eye just to see if it would stop. Nothing!
Naturally, I have used Repair Permissions, etc.
Anyone have any idea what is going on?
How about a Third Party repair program? I’ve used Disk Warrior and Norton in the past. Any new/better one’s that you could suggest?
Thanks for your help.

Thanks, J.C., but the "flash screen" box is not ticked.
Sorry about the font size folks. No idea what is going on. Can I eliminate or edit that post now? Can't see anything as to how to do it.
I did download an ad blocker program. It looks as if the problem is no more.
Like I said, creepy. I just wonder want that flashing was???
Thanks for the help.

I have a HP Pavilion Elite d5100 ATX Desktop PC. On start-up, it froze at the HP flash Screen.

I have a HP Pavilion Elite d5100 ATX Desktop PC. On start-up, it froze at the HP flash Screen. It’s mostly unresponsive; will not access BIOs w/ f1 key; will not Recover w/ f11. It will respond at start-up to ESC, displaying “Loading Boot Menu…”, and w/ f10 “Entering Setup”, but never proceeds past message.I have never upgraded the BIOS I have disconnected and peripherals, net connection and replaced the CMOS battery. I have also followed a suggestion to disconnect the mouse and keyboard on start- up to see if they are the issues. Nothing is working.

Hi,
If you can enter setup, then go into the bios and see if the hard drive and the CD/DVD are recognized. If you can't get past the entering setup message then try the below procedures.
Unplug the PC and open it up. Clean out all the dust. Carefully remove and replace all the cables going to the motherboard one at a time. Do the same for the memory dimms and the video and sound cards if you have any. You might want to buy a can of compressed air to blow the dust out of the CPU heat sink. Plug your PC back in and give it a go.
Try this procedure and see if you can isolate the issue. Trouble Shooting Power Supply Issues. Don’t skip any steps.

Lightroom CC won't open. Flash screen flashes, but that's it. Uninstalled and reinstalled (with CC) but got the same result.

I installed Lightroom CC with CC App on Macbook running Yosemite 10.10.3. It says it's installed, but attempts to open it get only a momentary view of the flash screen, then nothing. I uninstalled and reinstalled but get the same result.

I can confirm that sign out of Creative Cloud, and sign back in works, as the post above says.
To Adobe: Creative Cloud needs to die horrible death. Please bring back regular licensing of your products. CC has been nothing but nightmare.

Flashing Screen - with new installation

I recently bought a new 60gb video ipod. My roommate had been using my computer, Windows XP, for his ipod, but is no longer needs to use my computer. I uninstalled his itunes and quicktime software from my computer so I could start clean with my new ipod. I install the software that came with my new ipod with a complete installation I plugged in my ipod. Itunes appears to detect my ipod but I have been watching Do not disconnect flash on my ipod screen for an hour. I have tried resetting both my ipod and computer multiple times, and have reinstalled the itunes software a few times as well. I tried updating the itunes software, but all my effort still leads me to the same flashing screen once itunes in operating. I can successfully eject my software using the itunes shortcut, but once the ipod is plugged back in I get the same flashing screen. Any help would be greatly appreciated. Thanks.

I have the same problem: flashing screen, however with one variation, Itunes does not detect the iPod. So I cannot change from manual to automatic because the Itunes says "no iPod detected". I have tried reinstalling the software, resetting the iPod, and the iPod updater will not see the iPod as well, so I cannot update the software on the iPod. This seems to be an extremely arcane system! Can anyone help me please? Windows seems to grab hold of the USB connection and mount it immediately as a hard drive interdicting the iPod software. Windows explorer sees the Ipod hard drive and I can even transfer files to it, but the ipod software does not see the files! So I'm in the woods on this one. Can anyone help me on this, please?

Red static, flashing screen on Apple TV. Brand new

I have three TV's in my house and the Apple TV is not working on any of them. The only results I get is on one TV, which is a red, static flashing screen vaguely displaying the setup screen. I have tried 5 different cables and a converter box, still with no results. I have taken the Apple TV to work where I hooked it up to a TV, my computer monitor, tested all 5 cables and it works fine. All my TV's at home have multiple HDMI ports and it doesn't work with any one of them.
I have also done the reset through ITunes, tried again with no results. Brought it back to work and it still works there. The TV's in my home are about 7 years old, could they be out of date already?! This is why I don't try to keep up to date with electronics. As soon as you buy something it it's already out of date. It's like buying a car ... depreciates $3000 as soon as it leaves the lot. Products are manufactured, released and the new version has already been built just waiting around for 6 months to be released. I hate this because I now have a paperweight that can't be returned because my wife purchased it through Groupon and they have a 14 day return policy which has lapsed.
cables I've tried
Amazon cable with Ethernet
1.3
1.4B
Not sure what the other 2 are
Does anyone want to buy a paperweight?

If its working with the monitor(s) at work then the issue lies with your TVs at home. It's hard to say what exactly, I have an ATV working just fine on a 8 year old TV so I don't think it's purely age that's the factor.

Black flashing screen while in photoshop..how to stop?

Only once I open an image and start working on it, I get this annoying black flashing screen I've already updated all my drivers and also tried a few things from google, but hasn't worked so far ...Anyone know the answer?

DIsable GPU drawing in Photoshop, or update your video card drivers from the GPU maker's website to pick up at least 2 years worth of bug fixes that you are missing.

Laptop won't start up past the flash screen.

I have a HP G72 laptop, and every time i try to start it the flash screen come up and than turn black and says "insert bootable disk and press any key". I have tryed to use Norton 360 to recover my pc but I get all the way to using the advanced recovery scan and it tell me it is unable to access the disk. please help

Sounds like the hard drive has failed and will need to be replaced. If you are still in warranty HP will send a replacement. If not a retail laptop SATA hard drive can be used. Just be sure to get one of at least equal capacity as the original in order to use Recovery Discs. It can be larger, but not smaller capacity.For instance if you have a 500GB hdd you could use a 750GB hdd but not a 320GB hdd.
You might first try reseating the hard drive to ensure it has a secure connection. In rare cases the drive can be jostled loose during transporting.

Multi-coloured flashing screen on play-back

I download movies from my camera via Picasa 3 and have no trouble viewing them in Picasa, but when I try to play them with QuickTime in My Pictures, or if I burn them onto a CD and try to play them all I get is a multi-coloured flashing screen while it plays. The colours are very pretty, but not what I want to see!! The sound is fine. I have installed QuickTime 7, but no change. I have been downloading movies and copying them on to CDs and playing them OK for about five years. This problem has only occurred within about the last year.

I am so very grateful to you. This has been driving me mad for ages and it's difficult when you don't really have the faintest idea what you're doing! Took me a while to find the Quick Time Control Panel(!), but now all my video clips are playing fine. Thank you so much.

Flash Screen with JWindow

Hi All,
I want to make a Flash Screen when my program start, and shows some information before hiding it and display the main window. I read from the forum that I should use JWindow to achieve what I want.
However, Forte doesn't have a JWindow template, I search for the site and cannot find much about how to use JWindow. Can anyone here kindly help me?
I want some sample code, or some resource about how to use JWindow.
Thanks

better try the following code

public class SplashScreen implements Runnable {
   JWindow          splashScreen;

Flash screen of but on

today, the screen flashed like universal accesses flash screen was on but it wasnt. i enabled it then disable dit but it still had flash screen. anyone know how to disable it? it gets annoying.

If your computer's sound is muted and an application tries to beep, the screen may flash instead. In addition, some text editing applications will flash the screen if you type a closing character in a document without an opening one present regardless of the mute setting.
In the first case, unmute the sound to stop the screen from flashing. In the second case, look through the application's preferences for an option to turn it off.

i iPhone 6 red flashing screen nothing working after down loading iOS 8.02

Hi nicholasfromdenhaag,
It sounds like you got at least part way through the update before it stopped going any further. Try the steps in this article for an update that didn't finish.
If you can't update or restore your iPhone, iPad, or iPod touch
Take care,
