GPS position updated connected question

Dear,

I now try to get my current location

According to instrucations here:

https://developer.BlackBerry.com/Cascades/documentation/device_platform/location/retrieving.html

and my post here

http://supportforums.BlackBerry.com/T5/Cascades-development/GPS-issue/m-p/2483917#M27417

I've solved the problem and the code works without error,

But when I call

bool positionUpdatedConnected = connect(src,
            SIGNAL(positionUpdated(const QGeoPositionInfo &)), this,
            SLOT(positionUpdated(const QGeoPositionInfo &)));

I had

positionUpdatedConnected  = false

Can someone help me why this result?

Thank you.

Hello

As Zmey pointed out in your other post, you must modify the declaration of your location of positionUpdated() in your GPs.h file. You must rework so that you do not need to specify the QtMobilitySubset namespace (as in your cpp file):

private Q_SLOTS:
    // This slot is invoked whenever new location information are retrieved
    void positionUpdated(const QGeoPositionInfo &pos);

To do this, put a using statement in your GPs.h file, which unfortunately is not always desirable. You could put

using namespace QtMobilitySubset;

But if you're worried about having "using" in your header file, you can limit the scope of what you need if you put

using ::QtMobilitySubset::QGeoPositionInfo;

These changes are necessary due to the nature of the connect() method. In my view, than it does not much more than the chain by comparing the quantities in SIGNAL() and SLOT() macros. The method parameters must match each other and how the methods are declared in their respective headers.

    Please help with solutions.

    Best regards,

    Yes, you can get the current Position. Example: Latitude, Longitude, Altitude etc...

    Check this URL, it had Development Guide for GPS.

  • Have to restore the ipod after downloading the update. Question, help please

    Hello!

    I have a large music library on my iTunes and so all my music does not fit on my iPod Classic 160 GB, which is fine.

    I have the latest version (last one that came out) the iPod Classic 160 gb.

    I have the latest version of iTunes.

    I use Windows 7.

    So basically I had no questions for recent years until last week.

    For a long time, I went through my collection of music [in view of SONGS] and placed check marks next to all the songs I want on my ipod.

    It's the way I like it. I have enough free space on my ipod for new music, I get every month so that it works.

    I connect the iPod to iTunes and SYNC my library, and it adds new songs I added to my iTunes library since I'm finally connected.

    Okay - here is the problem.

    Last week, when I connected my iPod Classic to iTunes, I got a saying there was an update to download.

    I am used to what is going on all the time with my iPhone, but I can't remember the last time there was an update for my iPod.

    Intrigued and not think what awkward or troublesome would come from him, I'm agree to download and install the new update.

    When he did download it says that it does not recognize the device (iPod). After searching for hours for help, I finally disconnected, stop, restart and rec-connected my iPod to iTunes.

    He says that he has no music on my iPod. I checked and it was not. He disappeared. ***!?!

    Fortunately, all my music was always in iTunes so I went with my library SYNC (again, I have the titles I want selected already). He said he could only and basically the only option was to reset my iPod to its factory settings. Because the way that my iPod is empty anyway, I thought, fine, so I did. I have restored its original settings.

    Later, I did the same thing after disconnecting. Shut down, restart, clean the cache and the registry, etc and then reconnected the iPod to iTunes. My first thought was maybe I should try to download the update again - since the ipod is empty at this time - what the *, why not - I would rather finish now than get my music on my iPod to be prompted to download new update, and start all over. So I clicked Check For Updates when my iPod was connected to iTunes and it said there is no new update. I don't remember the exact update, but I'm sure it was like 2.05 something, and what I have now (and had before all this happened) was 2.04 or something like that. So does well, no update? No matter what. At this point, I'm SO frustrated - I want just to SYNC my library via checked/selected songs and get back them on my iPod.

    When I went to SYNC, nothing happened.

    So I went to the tab that showed the music and it only gives me the option to SYNC my library of ENSEMBLE music (which is too large and does not fit on my iPod) - OR - I can go through this form on this page and browse and select the ARTISTS that I would like to add.

    It's so frustrating. First of all, I don't want to pass by and re - select all the songs I want to add - the main reason being - he did already - when you click on my library and select the songs view, you can see all the songs that I previously have selected/checked remains unchanged. Second, if I had to do it the way he wants me to all simply by selecting ARTISTS who will not work.

    Sorry for this long crazy question - but basically - how now factory - reset iPod Classic for SYNCING with my iTunes library with the songs of checked/selected, I already have checked - and not to go through and do it by limiting my will and have to select only the artist (not to mention that I did as I want).

    I appreciate any help or insight that someone could offer.

    Much appreciated!

    On the settings screen of the iPod summary (what you see in iTunes when you select iPod), there is a checkbox to Sync only checked songs and videos (wording may be different for your iPod).  Enable (check) this setting in combination with sync entire music library.

  • Get the GPS Position in a specific interval

    Hi BB-Devs,

    I m developing a BB10 application where I use the GPS location Services.

    I need to update my current position in a specific interval.

    First of all:

    In the corrugation Simulator, everything works fine. My position will be refreshed every x seconds.

    Yesterday, I deployed my application with debugging token to my Z10.

    It seems the app works.     BUT:

    When I change my position, the new position will not be updated as in the Simulator :-(

    In my console log, I see that my function is called every x seconds.

    Here is a code snippet of the function that is called in the intervall:

    function setAktPosition() {
        //First test to see that the browser supports the Geolocation API
           if (navigator.geolocation !== null)
           {
              var options;
              navigator.geolocation.getCurrentPosition(setAktPositionSuccess, setAktPositionError, options);
           }
           else {
              alert("HTML5 geolocation is not supported.");
           }
    }
    
    function setAktPositionError(error)
    {
       alert("An unexpected error occurred [" + error.code + "]: " + error.message);
    }
    
    function setAktPositionSuccess(position)
    {
       //Extract information about the users current position:
       var time = position.timestamp;
       var coordinates = position.coords;
    
       //Retrieve geographic information about the GPS fix:
       ap.valueLat = coordinates.latitude;
       ap.valueLon = coordinates.longitude;
       ap.valueAlt = coordinates.altitude;
       ap.valueSpeed = coordinates.speed;
       //var acc = coordinates.accuracy;
       //var altAcc = coordinates.altitudeAccuracy;
       //var head = coordinates.heading;
       refreshMap();
    }
    

    That's how I got to call this function in a specific interval:

    aktiv = window.setInterval("setAktPosition()", intervallInSec);
    

    However - the works of the intervall-function-call - but my application still get the top position - no update of position when changing my situation :-(

    Corsica, I did this in my config.xml file:

    
       access_location_services
    
    

    My application has requested when starting fist approvals of the location. I also checked this in the settings of the device of my Z10.

    Are there problems with the GPS location services in the webworks for BB10?

    Or is it not possible to achieve?

    I will be happy if anyone has any advice for me :-)

    Thank you very much!

  • Wire Vs sleep Vs MDS Http connection Question

    Hello

    Here's my situation...

    I created a thread for background based on this article:

    http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800451/800660/How_To _...

    Here is my code:

    / * Thread that runs in the background * /.
    the final private class BackGroundThread extends Thread {}
    private static final int TIMER = 15; minutes
    Private boolean _stop = false;

    public synchronized void stop() {}
    _stop = true;
    }

    Private boolean isCoverageSufficient() {}
    If ((DeviceInfo.isSimulator ()) |)
    (RadioInfo.getState ()! = RadioInfo.STATE_OFF & (RadioInfo.getNetworkService () & RadioInfo.NETWORK_SERVICE_DATA)! = 0) & {CoverageInfo.isCoverageSufficient (CoverageInfo.COVERAGE_MDS))}
    Returns false; a Simulator or a real device with sufficient coverage
    }
    Returns false; real aircraft with insufficient coverage
    }

    public void run() {}
    CoverageInfo.addListener (new CoverageStatusListener() {}
    {} public void coverageStatusChanged (int newCoverage)
    {Switch (newCoverage)}
    box (CoverageInfo.COVERAGE_CARRIER):
    System.out.println ("COVERAGE_CARRIER");
    GPS.this.sendPoints ();
    break;
    box (CoverageInfo.COVERAGE_MDS):
    System.out.println ("COVERAGE_MDS");
    break;
    box (CoverageInfo.COVERAGE_NONE):
    System.out.println ("COVERAGE_NONE");
    break;
    }
    }
    });
               
    While (! _stop) {}
    GPS.this.getPoint (); try to get a GPS point
    Make sure the radio is on and there is the coverage of the data
    If (isCoverageSufficient()) {}
    GPS.this.sendPoints (); Send the _Dans table to the web server
    } else {/ / blackberry is out of coverage}
    GPS.this.storePoints (); store the table _Dans on blackberry
    }

    try {}
    Thread.Sleep(Timer*1000*60); pause the thread for a set number of minutes
    } catch (InterruptedException ie) {}
    System.Err.println ("Error:" + ie.toString ());
    }
    }
    }
    }

    The 'getPoint()' method to get a coordinate GPS using LocationProvider.getLocation ().

    The method 'sendPoints()' send the GPS coordinated to a web server using the HTTP connection:

    ...

    HttpConnection con = (HttpConnection) Connector.open (URL); Open the connection URL
    con.setRequestMethod (HttpConnection.POST); POST method
    con.setRequestProperty ("Content-Type", "application/x-www-formulaires-urlencoded");
    OutputStream out = con.openOutputStream (); display the results in a stream
    out. Write (Data.GetBytes ());
    int responseCode = con.getResponseCode (); Send data and receive the response code
    If (responseCode == HttpConnection.HTTP_OK) {}
    success
    }
    If (con! = null) con. Close; close the connection to the URL

    ...

    The "storePoints()" method simply store the GPS on the Blackberry Persistent Store when the BB is out of coverage.

    When the Blackberry is trying to send a GPS coordinate, but cannot because it is out of coverage, GPS data are stored on the Blackberry. My thread can sleep for 15 minutes before getting another coordinated GPS. If the BB is on the cover in the next interval of 15 minutes, the two coordinates are sent (the current and that (or those) that have been saved on the device).
    It works very well.

    However, now, I would put up a CoverageStatusListener so my GPS coordinates would be sent as soon as the BB is on the cover (and not wait for the next 15 minutes).
    I tried to "COVERAGE_MDS", but he never seems to have triggered... but gets "COVERAGE_CARRIER".
    I have a post on this here: http://supportforums.blackberry.com/rim/board/message?board.id=java_dev&thread.id=6076

    My question is on the wire. Actually here is called the 'sendPoints()' method:
    box (CoverageInfo.COVERAGE_CARRIER):
    System.out.println ("COVERAGE_CARRIER");
    GPS.this.sendPoints ();
    break;

    However, since my son sleeps, this method is not able to initiate a connection HTTP using MDS. I get an error in timeout after 2 minutes.

    I'm not an expert on the threads. I think I have all the necessary parts of the code... but I'm not sure about how to reorganize this.
    Can anyone help?

    Thank you!

    The network connection should be asked by a listener method.  Do not perform any operation or the heavy within a method of transformation of blocking listener.  Instead, you can create a new thread from the method which could then create the network connection to send your data.

    Basically light location allows your GPS search of satellites in BB Maps or Google Maps or any other GPS program. If you enable location off, you're basically turn off your GPS capabiilties. Personally I have to take advantage of Google Maps and geotagging the photos I take.

  • DW 2015 update: Advanced question Options

    Probably stupid question; However, 20141, with its parameters, ftp etc, OK.  So I want to keep this version what update to 2015 for relief purposes.  So I remove the control by setting delete them older versions in Advanced Options.

    One question is: can I leave the control in the frame import precedents and preferences settings?

    Creative cloud offering more choice for Installations. Adobe Customer Care Team notes on the page: "of course, you are in control, so if you want to keep the old versions autour, or change if settings are migrated to the new version, you will be able to do as part of the installation process."

    So the question for a beginner like me is: If the settings are migrated to the new version and I chose to keep the old version of 20141, my version 20141 still has the settings it had before the 2015 updated?  And my first question, can I leave the check in the previous settings setting and import preferences?  If I let this will verified the settings to migrate to the new version, but also be kept in 20141?  I am confused/door on the term "migrate."

    This thread https://forums.adobe.com/thread/1876309 crosis lost all its ftp settings and he used the default settings on the update of 2015 and therefore had no previous versions to turn back to get the settings.  Was it a failed migration?

    In short, how can I, without screwing, to update until 2015 but keep my 20141 and its parameters, since losing the settings, including ftp settings, would be very expensive operations.

    Thanks in advance for any help.

    Yes & Yes.  You can continue to use both.  If you uninstall the previous version, DW 2015 will install along side 2014. It is not replace your current settings of the site.  It's just their copy in the file appropriate in 2015.

    That said, when I create a site definition, I make it a habit to immediately export it and my FTP settings in a STE file which I store in a convenient & safe.  If your site definition file is damaged for some reason, or migrate to new machines, these STE files are very important to have.

    I also keep my server, MySQL & FTP connection information in a Rolodex card on my desk for reference.  You can never have too many backups. Whenever I have to change the passwords, I put on a new card and discard the old one.   A card Rolodex of costs of store office supply about $20 USD.

  • ESXi update 5 questions!

    I had a problem: the network of the virtual computer fails sometimes, run all the virtual machines on the Internet all of a sudden, there is no problem with the ISP, esx ssh and remote connections work but VM network is out of service.

    I think the update-ing the esxi for patch 15/03/2012 (build 623860) will allow them to solve!

    There is a problem:

    I run VMWare ESXi Driver Rollup 2 version and I am about to update to build 623860, patch 15/03/2012, I run the command:

    esxcli software sources vib liste--depot=/vmfs/volumes/datastore1/update/623860.zip | more to see what it's going to upgrade and downgrade, but the problem is that this net-tg3 driver is decommissioning which I think causes me problems, as he provoked with the original image of esxi to August 2011 (you can see my other thread).

    Latest version installed:
    Broadcom_bootbank_net - tg3_3.120 h .v50. 2 - 1OEM.500.0.0.472560 (new!)
    Name: net-tg3
    Payloads: net-tg3

    This is the latest version, but the last patch will downgrade to:

    NET-tg3, VMware 2011-08-19 3.110h.v50.4 - 4vmw.500.0.0.469512 VMwareCertified Downgrade

    Question 1:

    How can I make it without her screw my network card, making it unusable?

    Using the same net-tg3 driver!

    Question 2:
    Is it possible to back up my current configuration of esx and use it to restore if something goes wrong with driver?

    If that's the case, then how?

    Before the update-ing, I wanted to ask here for help!

    I have no access to the machine, but someone is closely in case something happens and if something goes wrong with the network to be able to restore to the old version.

    The main reason for the update-ing, is the virtual computer's network fall suddenly...

    Thank you

    Catalin Alin

    And if you are worried to screw up your installation...

    You can restore the State before your update by pressing SHIFT - R to the ESXi boot prompt and select the other bootbank to boot from.
