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!

I don't understand why appear new decimals.
Hi Jorge,
Instead of using
Data.SetValue(FormatDouble.DecodeDouble(self.PKg));
use
Data.SetValue(FormatDouble.DecodeDecimal(self.PKg,Data.Scale)); //
This will take the second parameter of scale
You will see the desired results.
Thks,
Sanjay

Subject: Re: (forte-users) I don't understand why appear new
decimals.
Simply put, the problem stems from the fact that
floating-point arithmetic is inherently imprecise.
Rounding errors are common.
With doubles, you get 16 digits of accuracy. Beyond
that there is no guarantee.

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.

If you want the same behaviour as in the code with traffic lights, change
class MortgageApplet extends JApplet implements ActionListener {

class MortgageApplet extends JFrame implements ActionListener {
and change
public void init() {

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. -
I don't understand why I can't download for free the apps designed by Apple, such as Pages and Numbers, which are free with iOS 7. Can anyone help me?
The apps are free with iOS 7 if you purchased a new device after September 2013. The apps do not come free just because you are running iOS 7 now. Did you purchase or receive a new iPad recently?
If you did, are you using the same Apple ID to get the apps that you used to activate the iPad? If you are, sign out of your ID, restart your iPad, sign in again and go back to the App Syore and see if the apps show up as free.
Settings>iTunes & App Store>tap your ID and sign out. Restart the iPad and go back to the settings and sign in again. -
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. -
I am new to Final Cut Express and don't understand why I am unable to drag transitions into Canvas? Something wrong in my setup? It's not the overlays they are "on" so can anyone advise me please, by the way the "L" doesn't appear in the bottom left hand corner either? and by the way how can I get rid of that irritating Blue badge saying "AutoFill your contact details" all mine are in "address book" already!
You can't drag a transition into the canvas. If you're dragginmg a transition from the effects tab you drag it between the edit point of two clips in the timeline.
Make sure show edit overlays is turned on in the Canvas view popup. -

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... :(

I have done the softer update and now this system request a connection with a Mini HDMI connector for iTunes I don't understand why ?
DO I HAVE TO HAVE THE MINI HDMI CONNECTOR TO COMPLETE THE SOFTER UPDATE PROCESS ?You might be seeing a Micro USB cable (Not HDMI) that is because your Apple Tv is in Recovery Mode due to some reason and it needs to be Restored by connecting it to iTunes on your Computer. So if you have a Micro USB cable ( which comes with Android Smart Phones ) then try to connect your Apple Tv to your computer using the same and with the help of iTunes Restore your Apple Tv to Factory Settings. Go through the below Apple Support kb which says " If your Apple TV still does not respond or if you were unable to follow the above steps "
