The problem of the Canvas and JInternalFrame

I have some problem with the Canvas and JInternalFrame, my application contains serval internalframes and each has one canvas, but i found that canvas is at the top z-order of the window. so it result in that the canvas is at the same z-level, which confuse very much.
who can help me with this problem, thanks.

I think the problem stems from mixing AWT and Swing components (non-lightweight and lightweight)
if the reason you are using a canvas is for the paint method; do away with them and just use a JPanel (which you can use the paint method within)
hope this helps?!

When I have video clips on my timeline, they do not play in the monitor screen. I hear the sound track but can not see the image. To test if my new files are somehow the problem, I went back and used video files that I used successfully a year ago, and they no longer play in the monitor window. I hear the sound track, but do not see any video. Have I changed some setting that controls video playback in the monitor window?

Thanks for the follow up.
Missing in this equation were the version of Premiere Elements that you were using and the computer operating system on which it was running. But...
The deed is done. But.....Until now and after you went ahead and moved to version 12, we now learn what version of Premiere Elements you were using. We still do not know the computer operating system involved.
You just said Premiere Elements 10. Premiere Elements 10 is hit by a serious known display issue if the computer uses a NVIDIA GeForce video card/graphics card. In this issue, the only remedy is to roll back the driver version to about May 2013. The description of the problem and how to do the roll back are described in one of the Announcements at the top of this forum. What video card/graphics card does your computer use?
On another front, Adobe will be releasing a new version of Premiere Elements any day now. No one but Adobe knows the feature set for the new version. That type of information is announced at the moment of release of the new version.
So the remedy to the problem that you presented in this thread could have been...
1. Rolling back the NVIDIA GeForce driver version to about May 2013 if possible (Windows 8 or 8.1 64 bit, may not be possible)
2. Move to another version of Premiere Elements (which you did)
I offer the above for consideration so that you can review your decisions. We are pleased to learn that Premiere Elements 12/12.1 works for you.
Please do not hesitate to ask questions and ask for clarifications, but remember that the answers are in the details.
Best wishes,

I have a new hard drive and itunes and my computer (windows XP) no longer recognise my ipod. I also had the problem with the registry keys not being present but this has now been fixed. However i can no longer link my ipod up with itunes.

When I first tried itunes with my new hard drive there was the problem with the registry keys but something also flagged up about needing a signed driver. Is this anything to do with why Itunes and my computer no longer recognises when my ipod is linked up? Whatever i try under 'devices' my ipod is never available to sync up. If anyone can help I would be most grateful.

Thanks for your reply. Unfortunately this has not worked. I didn't have quicktime to begin with so I don't know if that makes a difference? After following the instructions, I get the "registry keys missing" problem appear again (which I've subsequently fixed again) and then when I connected the ipod I got the following message - 'Device driver software was not successfully installed'.
I've tried windows update but this doesn't do anything as '...the service is not running'.
Any suggestions?

When I try to make a new video, a window comes up that says,"The operation could not be completed," and then under it, it says,"No other information is available about the problem," what is happening and how do I fix it?

Hi
And without info - it's near to impossibly to help. Try my general troubleshooting note:
Troubleshooting note
When iMovie doesn't work as intended this can be due to a lot of reasons
iMovie Pref files got corrupted - trash it/they and iMovie makes new and error free one's
problem in iMovie Cache folder - trash Cache.mov and Cache.plist
Creating a new User-Account and log into this
This forces iMovie to create all pref. and cache files new and error free
Event or Project got corrupted - try to make a copy and repair
a Codec is used that doesn't work (even though iMovie and/or iDVD tries to / they fail in the end)
version miss match of QuickTime Player / iMovie / iDVD
preferences are wrong - Repair Preferences
other hard disk problem - Repair Hard Disk (Disk Util tool - but start Mac from ext HD or DVD)
External hard disks - MUST BE - Mac OS Extended (hfs) formatted to work with Video
( UNIX/DOS/FAT32/Mac OS Exchange - works for most other things - but not for Video )
USB-flash-memories - usually do not work
Net-work connected hard disks - usually do not work (most often not fast enough and WRONGLY FORMATTES as DOS etc)
iPhoto Library got problems - let iPhoto select another one or repair it. Re-build this first then try to re-start iMovie. When iMovie starts-up it first look trough this iPhoto library and if faulty it all Halt’s.
This You do by
First - close iPhoto
Secondly - on start up of iPhoto - Keep {cmd and alt-keys down}
Thirdly - now select all five options presented
THEN - WAIT a long long time (>20 hours are not strange)
free space on Start-Up (Mac OS) hard disk to low (<1Gb) - I never go under 25Gb free space for SD-Video (4-5 times more for HD)
external devices interferes - turn off Mac - disconnect all of them and - Start up again and re-try
GarageBand fix - start GB - play a few notes - Close it again and now try iMovie
Screen must be set to million-colors
Third-party plug-ins doesn't work OK
Run "Cache Out X", clear out all caches and restarts the Mac
Let Your Mac be turned on during one night. At about midnight there is a set of maintenance programs that runs and tidying up. This might help
Turn off Your Mac - and disconnect Mains - for about 20-30 minutes - at least this resets the FireWire port.
In QuickTime - DivX, 3ivx codec, Flip4Mac, Perian etc - might be problematic - temporarily move them out and re-try
(I deleted the file "3ivxVideoCodec.component" located in Mac HD/Library/Quicktime and this resolved my issue.)

I solved the problem by removing the file: 3ivxVideoCodec.component. after that, up-dated iMovie runs ok.
Last resort: Trash all of iMovie and re-install it

Why is Apple so bad at providing customers with information on what the problem with email is and what they are doing to fix it?

Why is apple not providing information on what the problem withe email is and what they are doing to fix, along with a time frame for fixing the problem.

It was because the problem was major. If you do not know tech, you should know that a two day outage usually indicates some type of virus, hack, or a bad software load that they had to unravel. The common way to solve that is to rebuild servers and put back into service. That takes time.
Apple did not want to admit this problem. My guess at this stange was that they loaded new software that might be associated with the new IOS and it crashed. To reveal this would be to cast into doubt their future revenue.
Either way. Run do not walk away from Icloud products and services. Apple has demonstrated they can not be a business partner.

Hello apple
I have the problem with my iPhone and my friends have this problem too.
My iPhone have the problem about calling and answer the call. When I use my iPhone to call I can't hear anything from my iPhone but the person that I call can answer it but when answer both of us can't hear anything and when I put my iPhone to my face the screen is still on and when I quit the phone application and open it again it will automatic call my recent call. And when my friends call me my iPhone didn't show anything even the missed call I'm only know that I missed the call from messages from carrier. Please check these problem I restored my iPhone for 4 time now in this week. I lived in Hatyai, Songkhla,Thailand and many people in my city have this problem.
Who have this problem??

Apple isnt here. this is a user based forum for technical questions. The solution is to restart, reset, and restore as new which is in the manual after that get it replaced for hard ware failure. if your within your one year warranty its replaced if it is out of the warranty then it is 199$

How you can solve a problem or find out on a dead pc if the problem relies on motherboard and not on processor or vice versa

hi.
I am working myself with computers , so there is one thing in my mind I wanted to be sure,which I couldn't find an answer for it!
because I had before totally black screen and the problem was damaged processor.
I am wondering how I can be sure as the last option when I get a black screen and there is no lihgts at all no any LED is lighting.totally dead pc.
how you can be sure then that the problem relies on processor and not on motherboard or vice versa the problem relies on motherboard and not on processor
because I can't say to the customer lets buy first a processor if it is the cause of dead PC and if not then we buy motherboard. this sounds not wise.
so I experimented first with my latop ,I pulled out the processor to see if I can see any LED light or any movement on the motherboard to be sure that motherboard giving me some clue that it is healty. I gave some light heat to de fan to let it turn ,because
it is working with heat sensors then I know that the motherboard is healty. but it didn't work.
I did the same with my desktop computer and the result is the same no any lights and no any movement on the motherboard . so now can some one tell me how you can distuingish as a last result which of this 2 components is causing dead PC. is there any
tool to test the motherboard or how asus,dell ect. they solve such a problem if the customer send to them a dead pc.
I know that the power supply also can cause dead pc but I know how to solve a problem with dead power supply. and I want to keep away power supply from this question. please do not tell me that Idon't have to pull out processor
because I am a technician and both of my computers are doing very good after this experiment.
thanks

Usually if you have some kind of hardware failure there is some beeping during POST or most motherboards now have LED indicators to produce and error message based on the type of failure
So if its bad memory, not place properly, mismatched, processor not inserted properly, mismatched voltage or voltage connector not present etc it beeps or generates the error id.
Power supplies can be tested for failure. There are some walk throughs for testing just them with a switch, paperclip or a jumper (I'd suggest not doing this if you are not familiar with the dangers of electricity).
Memory can be tested with memory diagnostics programs like Memtest+
Processors can overheat if the proper precautions have not been taken usually you will get a POST beep or error code for that.
If the motherboard has no response then do the basics first:
Check power connectors and power supply. Once you determine that is not the case move on to other items like graphics cards in all the way or memory.

Computer iMac7,1 has been giving sundry problems for sometime. Within the last six weeks I have reinstalled the OS (Snow Leopard),without affecting the overall contents of the hard drive.
±3 weeks later the problems became more serious and I againreinstalled the OS and installed OS 6.6.7 from the internet.
I used the option to restore from the external backup driveand went back some time as it was my intention to reinstall individualcomponent in an attempt to find out where the problem might lie. This hasintroduced an entirely new problem! If I open Time Machine from the desktop itappears that all backups from late 2009 to June 2011 are intact. But, in thiscase there are none of the restore functions &c on screen. The latter areonly shown if Time Machine is opened from the menu bar or from the dock but, inthis case, available are only backups in late 2009!
I also opened the Apple Hardware Test in an attempt toestablish the nature of the problem. The ‘quick’ version said there’s nothingwrong; the more detailed one reported “Error detected, 4HD/11/40000004.” I haveagain tried to employ this test but nothing I do can induce it to open!!!
What to do? I need help urgently and would appreciate anyadvice that offers solutions to the problem.

To check your S.M.A.R.T status open disk utility and click on your drive and then click on the info icon.

Ok, since this forum is for Photoshop Standard and Photoshop Extended, we don't know much about Photoshop Elements. There is a Photoshop Elements forum and I'll link it for you since they best know how to field your questions.

When Firefox freezes, how can I shut it down, and re-start it without it automatically going to the site which caused the problem in the first place ?

I have Firefox set so that when I start up, I have it set so that it automatically goes to my home page. However when it freezes, which it does on a daily basis, and I have to shut it down and re-start, it automatically goes to the site which caused the problem in the first place.
If I was a hacker, I would probably find it quite fun to design a virus to reintroduce bugs after they had been exterminated - except that Firefox seem to have got there first.

Here's how:
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box above the list, type or paste '''sess''' and pause while the list is filtered
(3) Double-click the '''browser.sessionstore.max_resumed_crashes''' preference and enter 0 (that's a zero) and click OK.
When Firefox resumes after a crash, instead of resuming automatically, it will display a list of your previous windows and tabs and you can deselect problem pages.
(This assumes it wasn't a private browsing session.)

hello! My iMac frozed and I had to switch the electricty supply off and on in order to start again the system, with the problem that the screen looks wierd, I tried to calibrate it... doesnt works any suggestion?

Dear Paul, thank you very much for your time and answer, I followed those steps, somehow it helped the performance of my Imac, is faster now, but the screen issue about the very High contrast colours is still there. Since I am a photographer I am very depending on the screen calibration. I am worried that I came to damage the video card when I shut down the computer from the swicth when It was frozed.

Thank you all for the responses. By process of elimination, I think the problem is the connection to the express in between the extreme and dock. I bought another express and tried it at dock, no luck, I then replaced new express where the one is between

I have an airport extreme and express setup. My extreme is in my 2nd floor office with windows facing the water. My dock is about 250 ft away down a very steep hill. I have the express about 100 ft down the hill in an electrical waterproof box attached to a tree as high as I could install. The signal is weak and I'm thinking I might have to buy another express. Any thoughts on the best setup for me. I ultimately want to control speakers(hard wired in) down at the dock with my iphone. I have a receiver coming with airplay built in.
Thank you all for the responses. By process of elimination, I think the problem is the connection to the express in between the extreme and dock. I bought another express and tried it at dock, no luck, I then replaced new express where the one is between extreme and dock, no better. I unplugged the express between extreme and dock and there was no difference. So I believe I am connecting to the airport express or extreme that is inside the house. Again because when i approach express that is halfway I reconnect. so if you can understand my chaos, I believe the express in between is not really connecting to the extreme inside my house. Yes, No? So I need to know how to know if the express half way down the hill is getting the connection from the the extreme in the house. This is wearing me out!!!!!

You are asking several different questions. If you need to store your photos, music, and movies on an external volume, you certainly can. Any externally connected hard disk drive will work, connected either directly to your Mac or to your Time Capsule as a shared volume.
You should not rely upon using that as a backup device though. Although you certainly may use it for both purposes, it is a better idea to have dedicated backup devices for a variety of reasons not limited to redundancy. You would not want to simultaneously lose all your pictures as well as your backup. If they are all on the same device, that could happen. Furthermore, a backup cannot back up the volume on which it is running.
As for adding an Extreme or Express, using its LAN port for your iMac, and then enable Internet sharing so you can effectively use the iMac as a "hotspot", you can do that too, but I am unclear on what benefit you believe this arrangement would convey for you.
An Extreme's Guest network is separate from its Main network; that is the reason for having it.

The problem with the warranty repair in Russia. I bought an Iphone without a contract in Paris, and now I must go there to have it repaired? In Russia, the repair takes only bought in Russia. Is this correct?

The problem with the warranty repair in Russia. I bought Iphone4 without a contract in Paris, and now I must go there to have it repaired? In Russia, the repair takes only bought in Russia. Is this correct? So I was told over the phone in service and support in the near future, I was not planning to fly to Paris. Just for the sake of repairing the phone to fly to Paris is expensive.
The problem of 100% on your phone, as trying to change SIM cards of different operator and the problem remains.
Phone is constantly losing the signal during a call, and often just disabled.
I bought 5 phones for himself, his wife and friends, and only I have these problems.
Very annoying.

Yes you will need to go back to France as the warranty is country specific except in EU countries. Or if you know anyone there they could take it to an Apple store if you posted it to them.

What is the problem in my account I could not download from the store, whether programs are free or non-free I hope you fix the problem or Chrho me and I repaired the problem

thank you...

Nobody here can fix your problem, we do not work for Apple. And I have no idea what "Chrho" means. Neither does Google.
So - exactly what happens when you try to download a program? And from where are you trying to download it?
