• Problem during recovery latitude and longitude

  Hello

  I'm trying to get the latitude and longitude using LocationListener, but every time I try to seek always returns 0.0. I've implemented the locationUpdated method, but there it always returns 0.0 for i.e. latitude and longitude. After when I started with Blackberry Maps and start the GPS Navigation in Blackberry Maps menu, so I start receiving the latitude and longitude after awhile.

  Can someone tell what I am doing wrong? Am I missing something?

  Hello

  I have solved the problem.

  I was not any operation in the providerStateChanged method and I think of what he would always return 0.0 always. I modified the code today and as shown as below:

  class LocationListenerImpl implements LocationListener
  {
      public void providerStateChanged(LocationProvider provider, int newState)
      {
          if(newState == LocationProvider.TEMPORARILY_UNAVAILABLE)
          {
              locationProvider.reset();
              locationProvider.setLocationListener(null, interval, timeout, -1);
  
              //Make the thread to sleep for some time.
              try
              {
                  Thread.sleep(2000);
              }
              catch(Exception e)
              {
                  System.out.println("Exception while making the thread to sleep");
              }
  
              startGpsNavigation();
          }
      }
  
      public void locationUpdated(LocationProvider provider, Location location)
      {
          if(location.isValid())
          {
              double latitude = location.getQualifiedCoordinates().getLatitude();
              double longitude = location.getQualifiedCoordinates().getLongitude();
  
              //set the latitude and longitude values fetched here.
              setLat(latitude);
              setLon(longitude);
          }
      }
  
      private void startGpsNavigation()
      {
          try
          {
              locationProvider = LocationProvider.getInstance(null);
  
              if(locationProvider != null)
              {
                  locationProvider.setLocationListener(new LocationListenerImpl(), interval, timeout, -1);
              }
          }
          catch(LocationException le)
          {
              System.out.println("Location Exception : ");
          }
      }
  }
  

  Once the LocationProvider is temporary unavailable I am reintializing it in startGpsNavigation.

  I hope this is the right approach because it solved my problem. Now, I'm getting latitude and longitude without having to start Blackberry Maps.

  Hope it would help someone else too.

• My photos and videos are not in chronological order, when I export the Photos app

  Hello. When I export my photos and videos from the Photos app on my iMac all the photos and videos are not in order. I need all the photos in good standing - I need to export about 5 000 pictures of the application in order for a meeting next week! Help, please!

  Ethan.

  This is not photo - it is a function of the viewing program (probably the finder) - once the photos are exprted form pictures you can see then in different ways which you control, Photos does not - by the finder you can view by name of son, byt several dates, by file size, etc.

  Usually, the best way to accomplish what you want is to export using the names of batch file numbeing and then sort by file name in the program viewing

  This code works for me, you can set a lower accuracy in meters (better accuracy) to ensure that you get a good Postal Code. My guess is (precision< 100)="" should="" be="">

  {
      qDebug() << "positionUpdated()";
  
      // Get a GPS fix with an accuracy of less than 2000 meters and save the coordinates for further use
      qDebug() << pos.coordinate().latitude() << pos.coordinate().longitude();
      double accuracy = pos.attribute(QGeoPositionInfo::HorizontalAccuracy);
      qDebug() << accuracy;
      if (accuracy < 2000) {
          double lat = pos.coordinate().latitude();
          double lon = pos.coordinate().longitude();
          source->stopUpdates();
          if (!saved) {
  // This saved bool is needed because this slot gets called multiple time even after source->stopUpdates() is called. Initialize it to false in your constructor
              saved = true;
  
              // Initialize QGeoSearchManager
              QGeoSearchManager* searchManager;
              QGeoServiceProvider* serviceProvider;

• Values of latitude and Longitude

  Hello
  
  I am new to Oracle optional, if I need to store values of coordinates of latitude and logitude as Oracle Spatial.What the values of coordinates of latitude and logitude should be?
  
  Y at - it standard latitude and longitude for Oracle Spatials format.
  
  Usually what format I have to do and what conversion I must used to store on the SDO_GEOMETRY object.
  
  If you give examples, it would be really useful.
  
  Thank you
  Vino

  The ordered values are stored as decimal numbers.

  For example, the value of longitude 147 degrees, 30 minutes is stored as 147,5.

  In addition, lat/long data is actually stored in a SDO_GEOMETRY object in longitude, latitude order (latitude, longitude, not).

  Thus, a point 147.5 long and-32,5 latitude is stored:

  SDO_GEOMETRY(2001,8311,SDO_POINT_TYPE(147.5,-32.5,NULL),NULL,NULL)
  

  I hope this helps.

• Certain files and folders are not detected by Windows Explorer (XP).

  I created 15 files in a folder on a shared network drive, associated with another computer. My computer is running XP x 64 v. 2003 SP2, and the computer server (the one with the shared drive) has v.2002 XP Pro (32-bit) SP3.  When I open the folder in Windows Explorer I see only 12 folders. When I tried to rename one of the 12 visible files to match the name of one of the 3 missing files I get an error (file exists!). What is all too weird, when I select all and delete 12 deleted records and previously missing 3 appears.

  Has also had a similar problem with entire folders. The Explorer does not see the folder but when I create a shortcut by typing the path of the folder manually and click on the shortcut, the name of the file appears in Solution Explorer!

  All files and folders are visible when I connect on the 32-bit computer. There is no difference between the files/folders regarding the permissions or security settings are concerned. Other users have experienced the similar problem. I tested this on 2 other computers on the same network. On a 32-bit computer, everything works fine, but on another 64-bit computer, I get the same question of file disappears.  It seems to suggest some incompatibility between Windows XP 32-bit and 64-bit XP systems.  Any suggestions how to fix it? It's really frustruting...

  The files appear when you refresh the Explorer window by pressing F5 (or view-> Refresh)?

  If so, this article may help:
