prevois
what i can do iam in very trouble please help meAre there any lengthy calculations being done in the paint() function? This can delay the repaint() after the update() function clears the screen area and make flicer bad. Mover any code possible out of paint() and have it done before update() is called.

I have problem in my project, please Help me, urgent
have problem in my project.
When i start using project, i recive a errore in flash player
if it possible troubleshooted for me
Problem fileThe problem is that you have left paper on the floor near the
wastebasket.
Please you have to do a little of the work yourself.
First, post a topic that has a title regarding your problem.
That way people who know about that problem will be more likely to
take a look.
Second, don't just say you have a problem and receive and
error. Shay what kind of problem and tell us what the error says.
Third. Most people won't download a file from any random
stranger off the net. So don't expect that is going to explain it.
Fourth, even if the file does explain it, why should a
stranger have to do all the steps that you should have done?
Fifth, do a little work yourself, what have you tried to fix
it?
Sixth. Just because it is urgent to you doesn't mean it is
urgent to everybody else.
So try some of these things and post back. -

public void createParamsgr(){

gr.finalize();

public void initImage(Image image){
gr = image.getGraphics();
}This code already runable. But my question is Why when I decide to move the createImage method into the method of initImage in TickerTape.class, then it come out the error with nullpointer, why like that? is it im make any wrong thing? Or any solution for me to make it correct. Thanks and appreciate!hi, thanks for your reply.
let me briefly explain to you,
now, you try to look at the createParams() method and update(Graphics g) method int Ticker.class, inside there also got
image = createImage(getSize().width, getSize().height);
tickerTape.initImage(image);
So, now I want to move the code:
image = createImage(getSize().width, getSize().height);
into the TickerTape.class but dont Why come out the error with:
java.lang.NullPointerException

When I try downloading apps from the app store it doesn't allow me until I have entered the security questions, the only problem is I have forgotten my answers. Please help me to find out how I can retrieve the answers back, thank you
Check the AppleCare number for your country here:
http://support.apple.com/kb/HE57
Call them up, and let them know you would like to be transferred to the Account Security Team. -
I have tried everything but I can't connect my iphone to my laptop. It says that apple mobile device failed to be installed. I have read everything on the internet and did everything but still am facing the same problem. Can you please help me.
Again without stating the trouble shooting steps you have taken, its hard to direct you with any information.
Try a different port on the computer.
Does the iphone beep when u plug it up. ?
Plug iphone into computer and give it 3 to 4 minutes to see if it connects and is running slow.,
Delete the apple mobile device from your computer.
Upgrade itunes to newest version.
Is you USB cord defective ?
Any USB 3.0 on your system ? .
Delete or Disable any antivirus program on your computer ?
I will tell u the problem is your computer not the phone.
We could do this for hours. -
Can i use debit card as a payment method on app store..if not,what else?? in case i don''t have credit card...please help
I don't think that debit cards are still accepted as a valid payment method - they are not listed on this page and there have been a number of posts recently about them being declined. You could try contacting iTunes support but I don't think that you will be able to use it : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page
If you don't have a credit card then are iTunes gift cards available in your country ? They are not available in all countries and they are country-specific (they can only be used in their country of issue), so you won't be able to use those from another country. -
I have installed the most recent version of Snow Leopard on my MAC, and I am trying to install Mountain Lion from the Apple Store. It will not install, because it says I do not have 2GB of memory, even though I have over 200GB available. Please help.
Welcome to the Apple Support Communities
One thing is the memory, and another thing is the hard disk space. You are telling me that you have 200 GB of free space on the hard disk, but the App Store is telling you that you have to install 2 GB of memory or more on your Mac if you want to upgrade to OS X Mountain Lion.
First of all, open > About this Mac > More Info, and copy "Model Identifier" here, so we can know what Mac you have got and how much memory you can install.
We recommend to buy the memory in OWC or Crucial (Crucial is cheaper and offers the same compatibility warranty as OWC) because you won't probably have any problem with the memory you buy there -
Hello I forgot my Security question of my Apple ID ? I don't kow what should I do and how to solve this problem ? could you please help ?
You need to ask Apple to reset your security questions; ways of contacting them include phoning AppleCare and asking for the Account Security team, clicking here and picking a method for your country, and filling out and submitting this form.
They wouldn't be security questions if they could be bypassed without Apple verifying your identity.

Developer 6 Timer Problem... Please help
Hi all,
I have installed Developer 6(Oracle Product) on my system. I am facing a strange problem whenever I try to use Create_Timer built in.

Please help urgently.
Regards
AnandUpgrade to the latest patch and the problem shoudl go away - this issue was fixed I think in 6.0.8.13+
You can also try setting Keey Cursor position to Yes on the item. -
I made a card using the iPhoto and when I click to buy it, it says that I did not fill all the frames with pictures and that I need to in order to purchase it, even though I did and have checked multiple times. Please help, it's for Mother's Day.
Before ordering your book preview it using this method - http://support.apple.com/kb/HT1040 - and save the resulting PDF for reference - the delivered book will match it.

No sound for incoming calls but it works using speaker and earpiece. I can't hear anything but the other party can hear me clearly. I was told it's hardware problem. Would anyone please help me? Thanks
This is an annoying problem for many people. Most likely your dock connector (on the bottom where you plug in your phone) is dirty or screwed up and is probably just coincidence that it happened after you updated. Some people have had success cleaning the port with a dry clean tooth brush. There is a long discussion going on at the thread I linked below. Good luck...

I need to by apps but it keeps asking for my security questions ;/ but forgot the answers to my security questions and the security/rescue email too (i dont have USA number to call please help me and send my rest to my email
You need to ask Apple to reset your security questions. To do this, click here and pick a method; if that page doesn't list one for your country or you're unable to call, fill out and submit this form.

I haven't updated my iPod in forever so when the new update came out I tried to update it but it kept freezing my computer so I had to manually shut it off and restart it. I have windows btw. Someone please help me !!!!!!!!
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
