My iPod touch bluetooth cannot discover my iPad nor mac air, but it can discover other devices... I don't understand why. My Mac and my iPad can't discover it, as well...
Thanks for this... I actually wanted to pair my iPad with my iPod touch so I can use the keynote remote app in my iPod touch to control my keynote presentations... I was able to control my presentations through wifi... I wanted to use the bluetooth since internet connection is quite slow.. The app tells me I can connect through bluetooth with my iPad but sadly, it can't... I've been trying to pair them but the can't discover each other... :(

When I try to share my iMovie video on to Youtube, an alert appears saying that my Youtube username and password are incorrect. I have shared successfully before so I don't understand why cannot do so now.
Hey.
Since you seem to have tried mostly everything, apart from exchanging the motherboard, I'd say you have at least one option left, and that's to reinstall Windows from the recovery partition / recovery discs. That might solve the problem, if this is due to a software-error. General updates etc. might not work to fix such problems, but a clean install should.
If that doesn't help, I'd say the problem is somewhere either with the CPU or the motherboard, maybe bad connections or some sort of malfunction that prevents the computer from coming out of the 100% CPU usage.

Last time i usually pay the purchasing item using my debit visa card.
after that i no more use the debit visa card.
i'm using mastercard.
now each time i want to purchase anything, i cannot pay using the mastercard.
when i insert all the details including the expiry date, apple will show an error. only the expiry date.
i don't understand why.Does it have to be an applet?
If you want the same behaviour as in the code with traffic lights, change
class MortgageApplet extends JApplet implements ActionListener {
to
class MortgageApplet extends JFrame implements ActionListener {
and change
public void init() {
to
public MortgageApplet() { -
I don't understand why a person who has been with a company for 6 years cant get a simple upgrade can anyone help figure that out?
Are you trying to get an upgrade before you're actually eligible? If that is the case, it doesn't matter if you've been a customer for 6 years or 6 days...if you're not eligible then you're not eligible. Some of your possible options are to pay full retail, do an early edge up (if you are eligible for that option), or buying a phone from some other source to use.
If your situation is something different then it might help to share that. The options may still be the same but it helps to know what exactly the issue is. -

Why can’t I select None when I edit my payment information?
http://support.apple.com/kb/ts5366
If None is not available - On your computer launch iTunes and click “iTunes Store” in the left navigation pane. Click the “down arrow” next to your name at the top right side of the page and click “Account.” Enter your username and password and click “View Account” to log into your account information. Next to your Payment Type, click “Edit.” Select the “None” button and click “Done.” Confirm that your card has been removed by returning to the Apple account information screen. Under Payment Type, it should say that there is no credit card on file.

I don't understand why recently with the new "pages" my computer stops responding. When I go to fix some grammar all of a sudden the little colored circle begins to appear and won't go away I restart my computer.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report — it will be very long and not helpful. -
Why is this an error??? I don't understand why it is... Help Please
Hi,
Ok, I'll preface this by saying there's a lotta code pasted in here but it really quite an easy question, I just need to post all the code so you understand where what came from.
Now.............the question I'm trying to do is to create an applet that has 2 buttons -- each button when clicked opens an application (one is a simple calculator, the other a Mortgage calculation app). When you click one of the buttons (calc or mortgage), that app opens infront of the 2 button menu so its in "focus". The button on the 2 button menu then switches to a "hide app X" button (ie: "Mortgage", changes to "Hide Mortgage"). Thus if you click the hide button, the app that was opened is hidden, and then that "hide" button switches back to the original "app X" button. Pretty simple.
Now, I have from my text book an example that does exactly this, with the simple calculator already in it, and with another app (a traffic light thing) where the Mortgage should be in my final product. I also already have the Mortgage applet I need to insert from another book example in place of that Traffic Light portion.
Now, common sense would dictate that I should be able to just copy my code for the Mortgage applet into the example that has the 2 button menu structure, and overwrite the code I want to get rid of (the traffic light) with the mortgage code & rename the menu buttons. Right?? A simple switch of one thing for another... but therein lies my problem.
I copied all the Mortgage code in correctly over the traffic lights, switched the button names, tried to compile it but I get one error....
Exercise12_17.java:52: cannot resolve symbol
symbol : method pack ()
location: class MortgageApplet
mortgageAppletFrame.pack();I don't understand why..... mortgageAppletFrame.pack(); was a simple rewrite from lightsFrame.pack(); like every other line...... it should work. I've gone over it for 2 days......... Anyone know why it comes up as an error???
Below, in order going down is (1)my code with the 1 error I can't solve, (2)the original menu example I tried to edit, and (3)the Mortgage app code...........
Does anyone know what my error is?? Help or a hint would be greatly appreciated........ Thanks.

}Does it have to be an applet?
If you want the same behaviour as in the code with traffic lights, change
class MortgageApplet extends JApplet implements ActionListener {
to
class MortgageApplet extends JFrame implements ActionListener {
and change
public void init() {
to
public MortgageApplet() { -

HT6312 I don't understand why you are holding our documents captive!
How can you NOT make it backwards compatible! I prefer not to install the latest IOS (as we've seen what happens, with the last IOS update) before I am comfortable with the update. This is irresponsible and not customer friendly. Basically I am S.O.L. if I have an older iPhone or iPad. Thanks for being so customer friendly.
James,
Sorry I did not realize it was User to User. Very funny, really. Who would you like the check made out to? LOL
So I went to login to iCloud (on my PC) and I was forced to update to a different version of iCloud that would no longer allow any devices below IOS 8 access to the Pages area. I just don't understand why thy (Apple developers) cannot make it backwards compatible. -
HELP!! Don't understand why my new phone won't work!!
HELP!! I just brought my iPhone home and went through the activation process. Everything was fine. Then all of a sudden, where the bars for service are... it says "Searching" and won't stop. I also can't get into anything. I press on the screen... nothing. I reset it twice... nothing. It's still doing it. I don't understand why and I can't speak to anyone in technical support right now. Has this happened to anyone else? I just want to cry because I bought this phone a few hours ago and it already is giving me crap! Someone help me!!!
it's a new account, but I was sending texts and everything was fine. now all of a sudden it keeps going on and off and won't let me do anything. Just says "searching"
it's really ticking me off!!! no one said there might be problems while activating it. I didn't pay this much money for a phone I can't even use! -
Don't understand why WSDL isn't valid
In Workshop 9.2, I'm developing an annotation-based web service. I imported my schemas and generated the xmlbeans, and after setting my input and output parameters in the service class, I tried to generate the WSDL from the service. For some reason, the WSDL is not valid, and I don't understand why. I'm sure it's a namespace issue, but I don't see it.
The enclosed WSDL is somewhat paraphrased from the generated WSDL.
On line 76 (marked with a comment), there is the first of several errors. It says:
"The input element is referencing an undefined message 'overrideRequest'. Check that the message name and namespace are correct and that the message has been defined."
Here is the WSDL:

--------------------After I made these changes and re-validated, I get a dialog that says "The WSDL file is valid however warnings have been issued. See the Problems view for a list of the validation warnings", and I see the following in the Problems list:
IWAE0053E An internal error has occurred running validation on project:RiskRatingContainer]:RiskRatingContainer, check the log file for details
In in my WSDL editor, the lines in question still have a red circle with a white "x" in the left margin, and the tooltip still reports the same errors as before.
In the "Error Log" view, I see the following:
*** ERROR ***: Thu Feb 22 12:10:09 PST 2007 org.eclipse.wst.validation.internal.core.ValidationException: IWAE0053E An internal error has occurred running validation on project:RiskRatingContainer]:RiskRatingContainer, check the log file for details
Just in case, I'll include my current WSDL again here.
