Screen that disappears on the event PhoneListener

Hello.

I create an object with the PhoneListener interface, and on the method of callDisconnected , I want to display a screen.  I am able to get the screen appears immediately after the end of the call, but what happens is that the screen for a short period of time, then disappears.  Attempt to failover to the active application has no effect.  Is anyone able to identify what I am doing wrong?  I tried several solutions.  Here is a copy of the callDisconnected code.

{} public void callDisconnected (int callId)
TODO self-generating method stub
        
Try
{

UiApplication.getUiApplication () .invokeLater (new Runnable() {}
public void run()
{
Make changes to screen here.
ServiceLogScreen _serviceLogScreen = new ServiceLogScreen();
Invalidate() call on your display requires painting
method to call.
UiApplication.getUiApplication () .pushScreen (_serviceLogScreen);
}
});
            
}
catch (System.Exception e)
{
Dialog.Alert (e.getMessage ());
}
        
}

I guess that this is because the phone application moves to the background when a call is disconnected. You push the screen in the display of the phone application stack, because UiApplication.getUiApplication () returns the reference to the phone application. If you want to push a screen in the stack to display your application of your receiver, you can either send a global event to your application (and your application will need to respond), or keep a WeakReference to your application and call pushScreen or invokeLater on this reference, provided that the underlying purpose of the UiApplication is not null.

    If this comes back clean then it is related to the material, and because the DMP files mention Genuine Intel I ran the cpu stress test first.

    Try this free stress test: http://www.mersenne.org/freesoft/

    Prime95 Setup program;
    -Extract the contents of the zip file into a directory of your choice
    -Double-click on the executable file
    -Select "all stress testing.
    -Select the test of 'Blend '.  If you have already run MemTest overnight, you can run the test of "Small FFFS" instead.
    "Number of threads of torture test run" must equal the number of processors multiplied by 2 (if you use hyperthreading).
    The best way to do this is to go to the Manager of the tasks of the figure... The performance tab - and see the number of boxes that appear under the CPU usage history
    Then run the test of 6 to 24 hours - or until you get errors [b](whichever comes first)
    The selection of Test and the file stress.txt box describes the components that insists on the program.

    Stop 0 x 124 is a hardware error

    If you are overclocking try to reset your settings to standard processor and see if that helps.

    If you keep getting the BSOD here are things more than you may want.
    This is usually hardware related, defective heat, memory or processor even if it is "possible" he is associated (rare) driver.

    Stop 0 x 124 - what it means and what to try

    Synopsis:
    A "stop 0 x 124" is fundamentally different from many other types of bluescreens because it arises from a complaint of material.
    Stop 0 x 124 minidumps contain very little concrete information, and it is therefore necessary to address the problem as a case of material in an unknown state of distress.

    Generic troubleshooting ' Stop 0 x 124 ":

    1) to ensure that none of the hardware components are overclocked. Material which is pushed beyond its design specifications - by overclocking - may malfunction in unpredictable ways.
    (2) ensure that the machine is sufficiently cooled.
    If there is doubt, open the side of the case (be aware of all the relevant conditions guaranteed!) PC and direct an electric fan squarely to the motherboard. Who will rule on most cooling problems (lack of).
    3) update all drivers related to materials: video, sound, RAID (if applicable), NIC... anything that interacts with a piece of hardware.
    It is best to run the latest drivers anyway.
    (4) update the BIOS of your motherboard according to the manufacturer's instructions and clear CMOS.
    Their website should provide detailed instructions on the brand and model-specific procedure.
    (5) rarely, bugs in the operating system may cause "false positives" 0 x 124 events where the hardware wasn't complaining, but Windows thought otherwise (because of the bug).


    At the time of writing, Windows 7 does not have to suffer from a defect, but it is nevertheless important to keep Windows up-to-date.
    6) trying (stress) test these hardware components that can be put to the test artificially.
    The most obvious examples are the RAM and HDD (s).
    For the RAM, use the 3 rd-party memtest86 utility to run several hours a test value. (6-8 passes to stress the ram)
    For hard drives, verify if CHKDSK /R finds any problems on (s), including "bad sectors".
    Unreliable RAM, in particular, is mortal, as well as software, and anything other than a 100% clear memory test result is cause for concern. Unfortunately, even a 100% clear result the diagnostic utilities does not guarantee that the RAM is free of any defect - only that none have been encountered during the test passes.
    7) as the last of the non-invasive troubleshooting steps, perform a "Vanilla" Windows reinstallation: just the OS itself without additional applications, games, utilities, updates, new drivers - or ANYTHING that does not come from the Windows 7 disc.
    Who stops working mitigate the problem of the 0 x 124, jump to the next step.
    If you run the "Vanilla" installation long enough to convince yourself that not a single 0 x 124 accident occurred, start installing applications and updates slowly, always stopping between successive additions long enough to get an idea of the question if the machine is still free of 0 x 124 breaks down.
    Smash back, obviously the latest addition of software may be somehow connected to the root cause.
    If the stop error 0 x 124 persist despite the above steps, and the equipment is under warranty, consider to go back and ask for a replacement that does not suffer periodic MCE events.
    Be aware that want to perform the subsequent hardware troubleshooting steps can, in some cases, void your warranty:
    (8) clean and carefully remove the dust inside the machine.
    Reinstall all memory modules and connectors.
    Use a can of compressed air to clean the RAM DIMM supports as much as possible.
    (9) If all else fails, start removing items of hardware one by one in the hope that the culprit is something non-essential that can be eliminated.
    Obviously, this type of testing is much easier if you have access to equivalent components in order to perform swaps.

    If you are in the situation to have completed all the steps above without a resolution of the symptom, unfortunately the most likely reason is that the error message is literally correct - something is fundamentally wrong with the hardware of the machine.

  • elements that disappears with the new update

    I have updated to the latest version of muse and asked a customer to make a slight change to their site. I checked the new version at the address of catlayst business and was glad I did, as items have disappeared from the new version.

    Fortunately, the old version is still alive so that you can compare.

    Here is the site of the former- http://mixupmcr.com

    Here is the version of the new Muse- http://magichatmixup.BusinessCatalyst.com/

    You can see when you click on the links at the top of the page the screen scrolls horizontally. on the old version, this leads to a black content area. the new version, however, led to nothing. give a moment and links also stop sending instructions to scroll in total and the only way to move around the site (empty) is to scroll manually.

    the boxes have not moved in the site file. they are always exactly where they were, but the behavior has completely changed and they may not make it in the browser (I looked for them everywhere!).

    I tried to rebuild the entire site in a file fresh and found exactly the same problem.

    What happens if you please, and how can I solve this problem?

    Thank you andrew. He took me to always come back to this, but I am grateful for the comments that helped me solve the problem.

  • How to create instruction text that disappears in the fields

    Hello, all.  I'm a noob in the hope of getting some help creating a form.

    My idea is to have the instruction text in a form field that tells the user what type of information to understand, but then have this text disappears when the user accesses the form (be it on click, or by typing the first character, or something else).  I'm sure it can be done with javascript, but as a noob, I have no idea how to implement such a solution.  Any hints/help would be appreciated.

    Thanks in advance,

    /TW

    Here's what I've used in the past:

    var message = "Please enter your name here:'"

    If (event.value == ") {}

    Event.Target.Display = display.noPrint

    Event.Value = message

    } else {}

    Event.Target.Display = display.visible

    }

    Add this to the "Custom Format Script" for the field that you want to view and edit the message according to your needs.

  • I can't delete cookies after update from version 9.0.1, also the opening, I have 2 new cookie files that disappear at the close of FF.

    I have uninstalled/reinstalled 9.0.1, is the same thing. Check my profile, cookies.sqlite is if FF is closed or uninstalled. When installed and opened, I have 2 new files, wal - cookies.sqlite and cookies.sqlite - shm, as well as of cookies.sqlite. Is this the reason why I can't delete cookies? Also, I and enabled AdBlock Plus and the navigation of private life. After update, I can't post anything in support of FF (this is my 4th attempt, Safari finally used to post) and files under Tools, as clear history are accessible, I shouldn't have a history to remove.

    (1st edition)
    Ok. I reinstalled FF 9.0.1 Safari, but not directly from Mozilla. I used CNet, now things work as they should. I have no cookies listed, except those I want. Private browsing does not work correctly. However, I still have these 2 additional cookie files; -wal-shm.

    (2nd edition)
    I spoke too soon. After accessing sites that I frequent, the 'ad' cookies are back (adbright, realmedia, 247realmedia) and cookies from the site are eliminated, only not here, spent. Now I can't connect to anything and am back to Safari to access the Support Forum of FF. Have I not a bug? Someone please help, I'm desperate, I hate IE, Safari, Chrome, etc. They have neither the level of ad and pop elimination - up that Firefox has; and they don't have the level of customization that Firefox has. 2 additional cookie - wal-shm files, are always there when FF is open and disappeared again the closure of FF. One last thing, I noticed, I have a request of support for Chrome file in my library. The cookie file Chrome could interfere with the FF cookies? I do not think, I have Safari, as well, and no browser has ever interfaced with each other before.

    (3rd edition)
    I have uninstalled/reinstalled FF, all my modules and also tried to delete the cookies.sqlite document in the FF profile file, nothing happens. I counted, there are 14 sites listed in preferences > privacy > pane show Cookies (no pun intended) and they are all sites of "ad". These sites are also listed as sites blocked in Adblock Plus. Until a person pick up, I give up, I don't know what else to do. He there was that the only time that cookies were gone pane show Cookies, every other time I have uninstalled/reinstalled anything, they were still there. So, until someone can help me, I'm stuck. The only thing I did is removed altogether-profile file. It's the last thing I want to do, unless I can save my favorites somewhere to return after reinstalling. If this is not corrected in the next few days, I can just try, too.

    I think I solved my problem. I activated the safemode, then activated each Add on, one at a time, reboot FF between each activation. I don't have the add-on TACO. I hope this is the end. Thank you for your response. I appreciate it.

    Little puzzle, this particular post was not the first in which I posted this question. However, it is the only one that I thought was actually posted on the forum. The first two attempts, I thought had not displayed. Today, there are all the posts with the same problem. So, I really thank Mozilla for their patience and all the people who have taken the time to read this and the other two positions. I apologize for the repeated messages. I really didn't know that they had been posted because I couldn't find their afterwords to edit with my attempts to fix this problem.

    Are we able to get to a command prompt?

    If so, what is the machine returns when we type the following command followed by ?

    winver.exe

    EDIT: also, I wanted to ask a few other questions:

    1. You mentioned that you thought that this machine has been renovated.  Where did this come from?
    2. Using Windows PE in your environment?

    If this machine was purchased just, it seems that there are traces of its former owners out there.  As is the case, you should probably format the machine and reinstall Windows later.

    Let us know.

  • Footers that disappears into the PDF generated from FrameMaker 9

    Three other writers and I are having a problem with feet disappearing into FrameMaker.  Here's the problem: in FrameMaker, footers appears correctly.  When convert us a book in PDF format, many of footers disappear.  We find that a footer (or a part of the footer) appears on the first page of the chapter, but then footers disappear in the rest of the chapter.

    Here is some info:

    ·        

    We use the frame 9.  My version is 9.0p250.  I also use Adobe Acrobat 9 Pro Extended, Version 9.3.2 and Adobe Distiller: Professional Version 8.1.3

    · We have been able to reproduce this problem by using several guides.

    · Oddly, footers appear correctly when I print a single chapter.

    · I tried to restart my machine and then only FrameMaker loaded (if memory problems).

    · I optimized the book file and associated chapters.

    · I experimented with different settings distill.

    Does anyone else have this problem?

    It is probably a symptom of the MS Hotfix that corrects a problem with the text in PDF documents endangered generated from several Windows applications (not just FM).

  • pointer that disappears with the laptop touchscreen 8 windows

    I just got an ACER laptop touchscreen v5-571.  I have no mouse and mouse pad to move the pointer.  It worked great until today.  The pointer is no longer visible.  I have configured to use the ctl key to see where the pointer is.  He shows me where the pointer is a large circle.  I tried to change some settings of the mouse.  The pointer is still not visible.  Any suggestion?

    I solved the mystery of the disappearance of pointer.  A few days before the disappearance of pointers remembered, I intend to show a movie via hmdi port.  In the darkness, I played with function keys.  Apparently I pressed the button "hide the pointer" (fn F7), next to the 'two screens' (fn + F6) key.   After press "fn" + F7 again.  The returned pointer.  No wonder that all the other suggestions didn't work.  I don't know if this info will help you, just to share.
