More pushScreen problems
Hey all. I can use pushScreen() successfully to make my first screen in the stack when my application starts first. On this screen, I call pushScreen() another to push a second screen. However, this screen does not appear on top of battery, but rather under the screen 1. What Miss me? Thank you for your help.
Notice that the main application called SplashScreen, who immediately called screen. After all, I see the SplashScreen on top, and if I close this screen, I see screen under it. Why is he not screen on top? Finally, how would realize that do not use the UI Thread all the time. My understanding is that I am blocking all this code runs before enterEventDispatcher(), but I can't think otherwise.
public class TestApp extends UiApplication {
// Hook from OS to start application public static void main(String[] args) { // Make a new instance of our application TestApp application = new TestApp();
// Start up the event dispatcher so we can handle events application.enterEventDispatcher(); }
private TestApp() { SplashScreen screen = new SplashScreen();
// Push the Splash Screen onto the stack pushScreen(screen); }}
// Now the Splash Screenpublic class SplashScreen extends MainScreen { public SplashScreen() { RichTextField helloWorldTextField = new RichTextField("Splash!"); add(helloWorldTextField);
// Immediately push the HomeScreen synchronized (UiApplication.getEventLock()) { UiApplication.getUiApplication().pushScreen(new HomeScreen()); } } }
// Home Screen
public class HomeScreen extends MainScreen{ public HomeScreen() { addMenuItem(new SetNewAlarm());
RichTextField helloWorldTextField = new RichTextField("Home!"); add(helloWorldTextField); } }
Your code first calls pushScreen (HomeScreen) (from the inside of the SplashScreen constructor), and then call pushScreen (SplashScreen), which makes the SplashScreen appear on the home screen.
To repulse screens after the event dispatch loop is started, you can start pushing the screens from inside the UiApplication.activate or Screen.onDisplay (and tastes).

Hello! My computer hung on me for quite some time, so a few days ago I had no choice but to make a closed group. Now, I can't even as much as screen (with the blue bar and the Windows logo). I tried the following:
(a) via the Windows Recovery Console chkdsk. I tried / p, / r, / f, all give me a "volume contains one or more unrecoverable problems." or something like that. If I try to install a new Windows, as soon as it "looking for previous versions", I get a BAD_POOL_HEADER blue screen with stop error message 0x000000C2.
(b) I tried to hit every single F shortcut key, but none would let me go in the recovery console (which is F10 for me) and safe mode (which is F8 for me). Only the F1 works, who has access to my bios Setup, I think.
If I jump just the recovery console, I just get a white loading bar, who finally stops loading, and then I get a message telling me that one of my files (windows\config\system I think) is missing or damaged. I tried after a few steps through one of the Windows solutions to counteract this, but I can't even copy/delete files via the command prompt that it denies access.
Help, please!
Hello
· What is the number and the model of the computer?
You can check the link below
Regarding the BAD_POOL_HEADER error, according to the research of mu, it points to be a hardware problem with the memory or a driver issue as possible.
We can offer further assistance once you are able to boot XP. Overall however, looks like some ongoing hardware issues.

What to do about CHKDSK message "volume appears to contain one or more unrecoverable problems".
My XP Home just quit starting all along. Previoously before leaving he would do a CHKDSK scan and then go over to start. Now, it closes a few seconds after the Windows screen comes up with the dots that runs through. The Windows image stays on the screen, but nothing else happens. I put in my XP disk to run the repair and got at the C:\Windows prompt after all the various commands of the finish. Then I typed CHKDSK and Enter. The first time that CHKDSK has stopped 38% full. The 2nd time it finished and gave me the error message: "volume appears to contain one or more unrecoverable problems".
I sure would appreciate it if someone can suggest my next move to get XP running back?

Time Capsule gen more recent problems PPPoE
Hi, I have problems with the PPPoE connection in last TC with 7.7.7 firmware on it. When I put my dsl bridge modem and use the pppoe client in TC he just can't get IP address. I need reboot/update of TC for like 10 times or more to make it work. When I put my dsl router mode and I use TC only as DHCP server it works perfectly. What is the problem? Should I get RMA?
I discovered, when I enter my details PPPoE client PPPoE TC and I put any name service, that I can not get the Internet to work, when I erase this service name I get all green lights and BAM, my internet connection works. But now is real problem, when I want to change something, for example DHCP reservations or anything else. If I click on update and the Service name field is empty so I can't have a internet connection. I need to re - enter any name service, and then the update, and then clear the name of the service for the empty field, then the work of internet connection. So I need to restart TC 3 times if I want to get internet connection.
Think it's a bug in the firmware a little? I had this problem on 7.7.3 firmware also Pls help

iPhone 6s more vibration problem
My iPhone 6 s more than 128 GB is barely 2 months old and has been treated with care since the first day. I started to notice this buzzing/clicking sound when the phone is held vertically. The noise varies depending on how I want the phone.
After some googling I found reports of similar problems on the iPhone 6 Plus.
I made a video of my problem here: https://www.youtube.com/watch?v=6Kcf1pwBg9w
Everyone knows the same thing?
If anyone knows the problem is irrelevant. Polls and surveys are banned by Apple Support communities terms of use.
It is under warranty. Make an appointment at the genius bar and get it fixed / replaced.

45 days ago, I bought an iPhone to my brother as a gift 6 with 120 GB of storage.
Everything went well. He used iTunes, in order to install anything for the new device, until last week, when something happened suddenness.
Every night he changes his mobile, but all by the sudden sometimes when he turned off the nm the next morning, the display will show the battery icon empty, although he left 60% charged, the nit before!
This symptom occurs half the time he turns on his iPhone 6 more last week.
Is this a hardware problem? (which seems the most obvious)
One software, or a combination of both?
This is what there return to Apple for replacement, or it can solve the problem by a solution 'House '?
Any help will be appreciated
Thank you for your time

Try resetting your device. This will not erase your data stored on that device.
- Press and hold the sleep/wake button
- Press and hold the Home button
- Press and hold both buttons until the display turns off and on again with the Apple logo on the subject.
Alternatively, you can go to settings - general - reset - Reset all settings
If that doesn't work, restore your device to factory settings. Please note that this will delete the data on your device.
Take a look this Apple Support article: use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.
If these steps do not work, contact Apple and ask for help.

I had to reinstall XP. Before reinstallation, D drive was the drive started on my computer and I have not had any problems with space. Obviously I screwed up letting it keep the partitioned drive or what I had to do at some point, because after reinstalling XP C drive the drive that begins (C has no space and D wants everything as before). Now, I don't have enough space to download programs, I need to work from. In fact, I don't have enough room to do anything! C drive only has 7. something GB on it compared with with 30 0r 32 GB!
How can I get the D drive and do what is now drive C? Alternatively, I can change somehow D drive where all downloads to go and work from there anyway? I don't know how to change where a download will. Can someone please help me out here because I'm way behind with work; cannot afford professional maintenance COMP.; and have no idea what to do.
Hello
You may need to back up important data on the computer and and then format the D; drive to remove all the installation files and creates the disk space.
Also I suggest you perform a disk cleanup on the computer. To get the procedure you can refer: Description of the tool in Windows XP Disk Cleanup: http://support.microsoft.com/kb/310312
And uninstall unwanted computer programs, see: remove programs you don't need more: http://www.microsoft.com/windowsxp/using/setup/maintain/removeprog.mspx

Valet parking more speed problem
I recently installed a new Valet Plus and noticed much more slow navigation and then from my old D - Link DIR-655 router. I ran speedtest.net and noted my speed died in 15 Mbit/s of my usual 30 Mbit/s. After many trials, I discovered that the router option "" safe surfing"was the culprit. I did a 'chat' with a CISCO technology session and ran a lot more tests. There is no other explanation, then the safe surfing must do some filtering it slows down. If anyone else has noticed this? This seems to be a significant problem for CISCO.

Resolve stop (blue screen) error in Windows 7
Stop (sometimes called blue screen or black screen error) error may occur if a problem causes Windows 7 to stop or restart unexpectedly. You might see a message that says: "Windows was arrested to avoid damaging your computer."
These errors can be caused by hardware and software issues, and it can be difficult to solve the problem.

DW cs5 (not responding) for 5 minutes or more, other problems
- If I do a manual my machine virus scan, the minute the scan begins, dw becomes locked and MISTLETOE refuses to redraw and one might even say (not answer).
periodically for some unknown reason, (seems to be ANY disk access by some background app?) usually dw freezes during this time about 5 minutes after the drive is over. Sometimes it is shorter, but usually aren't.
- in all dw cs5 models included, UTF-8 charset (should be capital to meet the w3c validation) is utf - 8.
- < script > < / does not close the tag html5 Pack. or anything with SVG or MathML, which are part of HTML5.
- the complete set of the css3 modules and the CSS 2.1 specification are not supported in the HTML5 pack. I would like to do some tests of browser. I also want my investment in the future! not to do just what is.
- all of the tags HTML5, attributes, entry of items types according to the standard w3c are not included in Insert, portion of the tag from the menu in the HTML5 pack.
- highlighing syntax for javascript clearTimout() is different from the syntax for setTimeout().
- syntax highlighting is not done correctly for situations where there are 2 /'s on a line in javascript, as when there is math (division) and / / end of the line. It's bad lexed as a regular expression. It really bothers me when I'm coding.
- There must be a fixed refresh button to reinterpret code/code + design/design view when changes have been made and something is not as a failure of refreshment, or when a problem has been fixed and you would like to see if any broken left tag dw.
- functionality in dw you set in prefs which is supposed to 'correction with missing/incompatible labels documents' and other does that. He made a lot of noises that she does, but never does anything everything except throw a dialog box. I want to fix the document as I told him. broken functionality. as it is, I do a lot of assumptions as to where those broken tags are, because dw to highlight either. I designed an algorithm that I use in my program bracematcher to https://sourceforge.net/projects/bracematcher/ interest you that marked the orphans of the opening tags and closing. I'm sure you can do it yourself, it takes just knowledge of recursion and stack and using the == and! = It's very simple. Thought I might even be able to rewrite my program to work with labels, which would make it an even more exciting program. the lexer and manipulating strings is the hardest part, and HTML is weird with ropes on the attributes. I really need to do since dw is not highlighted my problems of tag. at least I can get a detailed report of the problems with my tags.
McAfee & Norton are notorious resources hogs. No matter how much memory you have, they will take over your computer. And they frequently cause other apps slow down or stop responding until the VA finishes everything he does. I'm so bored with the AVs albums that I actually considered not using any at all. Finally downloaded MS Security Essentials. It's great! No more intrusions or memory leaks.
I think "the cloud" is highly overrated. expensive during these times.
At the beginning I thought also, but at closer look, Creative cloud looks more like a victory, victory for multiple users of the product. Where else can you find 17 products for the price of the intro to $29.99 / month?

iPhone 6 more battery problems?
I got my iPhone 32 gb gray space 6, with for about a year 1/2 now. It worked perfectly for 1.5 years, but now there seems to be a problem. My iPhone battery life will increase from 3% (not connected) to 15% while it is plugged instantly. Then when it is removed say 15 minutes later the dough goes straight back to 2,1,4,3%. And when my phone is charged a good amount as 75% of its battery life runs out pretty quickly. About 45 minutes if you are on instagram. My family has had the same problem and its diagnosis of apple was a manufacturing error. It was just like my situation, everything's fine until the battery starts to spoil. The Apple store was going to give him a replacement, but she told them that they had purchased a new battery to put inside. That did not work for them. But the store said that they could not provide a replacement due to the fact that the iPhone had been "worked on". If I receive a replacement? I have to pay something? They could send me a replacement?
According to Apple, only Apple or Apple authorized service providers are allowed to maintain the phone, without losing any warranty or out-of-warranty service options, including the replacement of the battery or the screen.
As to your question, visit an Apple Retail Store or an authorized service provider would be the quickest way to find out if your battery needs to be replaced after 1.5 years. According to the use of the phone, it may be necessary.
But if they do not find a battery fault, you will have to pay for the new battery.
You can also contact Apple Support for that, they can also test your battery online. However, shipping and replacing the battery may take longer to make an appointment at the Apple Store.
