• 5 Lightroom sometimes fails to load EXIF GPS data from .jpg files

  Until I Lightroom, I used geoSetter to add GPS data to my .jpg files. Most of them have loaded up in LR without problem, but for some of them, Lightroom could not import the GPS data. I used to compare GPS data in the loaded files OK and those who have not noticed that some of the problem files do not have exiftool: GPS, GPS Time Stamp, dater GPS map data. I used exiftool to change these in the file, Lightroom still not managed to load GPS data.  Anyone has an idea why Lightroom 5 sometimes fails to load EXIF GPS data from .jpg file

  But the XMP section contains an incomplete set GPS fields. Note that XMP:GPSDateTime specifies a time other than EXIF:GPSTimeStamp.

  I don't know which of your programs may have created these XMP values false, incomplete, but they confused LR.  According to the specifications of the Working Group of the metadata, which accepted LR, LR, choose the EXIF GPS values and false XMP values should not confuse it. But LR is preferring the XMP values and then conclude it is not all the GPS coordinates.

  You can work around this bug in LR by doing:

  ExifTool - xmp: gpsdatetime = - xmp: gpsversionid = file

  Hi Colin,

  When you read back the data, there is a parameter called "Bytes read" you need key, the default value is 1024, in this case, it will keep waiting for 1024 bytes until the timeout occur.

  I found a good article talk to this topic and you can change the bytes to be read in the test environment LabVIEW or MAX.

• How to read in data from MySQL to Authorware?

  Hello
  
  I'm reading in my authorware (MySQL) database values, but the best I can do is either true or false.
  I would like to be able to get data from the database and return to AW as a string. Does anyone have experience with this? If anyone can lend a hand in this company?
  
  Thanks in advance for your help,
  
  Brad

  You'll need some sort of middleware of script, such as PHP or your ASP.
  script will need to:

  * connect to the database
  * query the database
  print the query results

  I use ReadURL to send variables AW to my PHP script, script recovers
  These values and assigns the variables used in the query. Print
  results are returned to the ReadURL. You can also use PostURL.

  In AW, my code for retrieving information from the database looks like this:

  ==================
  Action: = '? action = getData.
  query: = '& student_data_id =' ^ student_data_id
  URLString: = db_loc ^ 'retrieve_data.php' ^ action ^ query
  queryString: = ReadURL (URLString)
  ==================

  I Specifies an action so that the script can contain code for more than one
  the purpose of the trip. My PHP script looks now like the return line (the spirit):

  ==================
  

  include a script not cached
  include (' lib/no_cache.php');

  connect to the database
  require_once ($_SERVER ['DOCUMENT_ROOT'].)
  '/.. (/ php_secure_scripts/check21/mysql_connect.php');

  create empty var for the holding of output to send to the Authorware
  $output = NULL;

  define queries
  If ((isset($_GET['action'])) & ($_GET ['action'] == 'login')) {/ / set}
  connection request
  $salt = get_salt();
  $query = "SELECT student_id, first_name, last_name, INST_ID select OF.
  students WHERE username = ' {$_GET ['username']} "AND
  password = ENCODE ("{$_GET ['password']}', '$salt'");

  } else if ((isset($_GET['action'])) & ($_GET ['action'] == 'getUserInfo'))
  {/ / set getUserInfo}
  $query = "SELECT inst_name, e-mail, student_data_id, active COURSES."
  LEFT JOIN students student_data USING (course_id) LEFT JOIN to HELP
  (student_id) Using (select INST_ID) WHERE LEFT JOIN institutions
  students.student_id = {$_GET ['sid']} AND courses.sku = {$_GET ['SKU']} ";

  } else if ((isset($_GET['action'])) & ($_GET ['action'] == 'getData')) {}
  query Set getData
  $query = "SELECT course_data, quality, increased FROM student_data WHERE."
  student_data_id = {$_GET ['student_data_id']} ";

  } else {}
  Exit();
  ECHO '.

  No selected query.

  ";
  }

  query the database
  $result = @mysql_query ($query);

  $row = mysql_fetch_array ($result, MYSQL_ASSOC);

  foreach ($row as $key-online $value) {}
  $output = $output. "&" . $key. "=" . $value;
  }

  print $output;

  Close the database
  mysql_close();
  ?>
  ==================

  The returned data is saved in my AW variable called 'queryString' which
  I then analyze in AW. My database connection code is kept in a separate script
  in a location on the server that is not available for browsers. The script
  also contains a custom function that returns a "germ" for the password
  encoding.

• How to implement the reading of data from a matte file on a cRIO?

  Hi all!

  I'm still not sure, it is plausible, but I'll ask rather before you begin complicating. So far, I found no useful information on reading in the data to a device of RT from a file (type of a simulation test - data is simulated).

  I have the MatLab plugin that allows the storage of data read a MAT file, which has a number of columns that represent the different signals and lines representing the samples at a time (depending on the time of the sample - sample every time has its own line of signal data).

  I have no idea how to implement this at cRIO.

  The idea is:

  I have some algorithms running on the controller of RIO in a timed loop. As the entries of these algorithms I need to access each of the values of columns in the row, which is the time of the sample (sort of a time series - without written actual times).

  I am fairly new to RT and LV development, so any help would be appreciated.

  Thank you

  Luka

  Dear Luka!

  I think the reading of all the samples in a single channel is exactly what you need here, because reading the files may take some time and is not deterministic, so it is best to read all the data in memory (or if this is not feasible due to problems of size, fairly large pieces may be sufficient). The table read can be provided and then in the loop simulating outings, something like this:

  

  I used here separate channels so it's more graphic, but you can build all the channels in a 2D array and array index corresponding to the samples fom 1 who. You can also use for loops with indexing as tunnels are setup and then you won't need the index functions and the number of iterations is also set automatically, but you have to take care of synchronization settings.

• Reading the data from an Excel file

  Hello

  I try to use the attached VI (adapted from an example provided by someone else in a different thread) to read an Excel file.

• pl/sql block, reading the reading of data from the table to a single point in time

  I'm trying to figure out if several cursors in a PL/SQL block are executed inside a single Point in time, and so don't see no updates of paintings by other processes or procedures running at the same time.
  
  The reason why I ask is I have a block of code as an initial extraction of data, with some Sanity Check before the code runs. However, if another procedure might modify the data between the two, then the mental health check is not valid. So I am essentially trying to know if there is consistency read in a PL/SQL, preventing updates to other processes to be seen.
  
  Anyone who has an idea?

• Reading the data from a fichierXML

  I was given a measurement file that is stored in XML format, I need to extract some data.  I spent a large part of the morning passes through all XML I could find trying to figure out how to start.  I also downloaded the packages GXML and EasyXML VI.  The problem is that I can't seem to figure out how to use one of these files because all of the examples I see are beautiful small files and I don't know how to apply them to my folder.

  The first thing I'm doing is to extract data, called CentralTilt.  If I look at the XML mapping in Excel it would report the acquisitions-> SystemConfig-> data.  In Excel when I extract these data, I get a column of values about 1200.  I'm trying to do the same thing, but place them in a table in Labview.

  At the end of the day, I need to do a several other values in the file and then perform additional handling, this is why I would try to automate this process in Labview.  I think that if I can just go beyond this first hurdle to not really understand how these different functions of XML called on the file and analyze the data I should be able to figure out the rest.  Some advice would be appreciated.    Thank you.

  Unfortunately, I can't post the file as it is too big, but I have a screen capture of the XML mapping.

  

  Received warnings during conversion, you may need to replace a part of the used screw (load and close screw).

• PC can not read audio data from any media player

  computer laptop windows 7 my mother began to just expose some strange problems. She is unable to play any of his music on his pc using WMP12. the same files will also not play using iTunes, but I can cancel the iTunes issue for now because the problems are related. I was able to get the files to play on my PC in WMP12 across the network, so the files themselves are not at fault. work the system sounds in Windows, but when I say WMP to play a wav file, it errors out as well. I tried to reinstall the audio drivers, and run the troubleshooter of wmp and the resolution of the problems of audio playback, but nothing wrong was found. SFC has found no problem either. before resorting to more drastic measures (restore, reinstall, etc.). I well I ask here to see if I could get assistance.

  Seems rather strange, that my first thought is to check the volume, in windows 7, you can set the volume for different applications, like Chrome. I don't see anything else I'm afraid. You hear the music when played from YouTube? If so, it may be a problem in the settings for music apps, in general. Another idea would be to try to install K-Lite, to ensure that there are no problems with codecs.

  Except that I can not think what you could make, but restore to a time where you could play music.

• reading the data from an object

  I know how to do something like that to show an ID value:

  My $basevm_view = Vim::find_entity_view (view_type = & gt; 'VirtualMachine', filter = & gt; {'name' = & gt; "myguestvmname"});

  Print "my ID =". "." $basevm_view - & gt; Summary - & gt; config - & gt; ID. "\n";

  Can I get the ID using the accessor method? If so, what is the snippet of perl code that prove? I'm trying to understand what all of the accessor methods are for, so if they are not for this sort of thing, a quick explanation would really help this newby.

  Thank you.

  As has been pointed out by William, it is not really of accessor methods directly and as you have discovered, the object is exposed as a series of nested, anonymous hashes.

  You can create a utility function if you want a cleaner accessor.  It's probably a good idea since you can create exceptions in there and avoid a lot of messy test code in your branch of the main logic.

  Something like the following would be a good starting point:

  #!/usr/bin/perl
  
  use strict;
  use warnings;
  
  use VMware::VIRuntime;
  
  Opts::parse();
  Opts::validate();
  
  Util::connect();
  
  my ($host_views);                                   
  
  $host_views = Vim::find_entity_views( view_type => "HostSystem",
                                                );
  
  foreach ( @{$host_views} ) {
       print "summary.config.name = " . get_value($_, "summary.config.name") . "\n";
       print "summary.managementServerIp = " . get_value($_, "summary.managementServerIp") . "\n";
       print "summary.bogusProperty = " . get_value($_, "summary.bogusProperty") . "\n";
  }
  
  sub get_value {
       my ($entity, $value_path) = @_;
  
       my @keys = split(/\./, $value_path);
  
       my $key_ref = $entity;
       foreach my $key ( @keys ) {
            eval {
                 $key_ref = $key_ref->{$key};
            };
            if ($@ || not(defined($key_ref)) ) {
                 return '';
            }
       }
  
       return $key_ref;
  }
  

  Example of output:

  summary.config.name = vlab-esx-01.vlab.local
  summary.managementServerIp =
  summary.bogusProperty =
  

  That function will catch at least undefined properties (not all the properties of the SDK are guaranteed and access them may throw an exception).  To do this, he makes an empty string to avoid warnings from perl on indefinite concatenations.

  Keep in mind if you are using the properties-online arguments appointed for your find_entity_view calls, you will need to access the properties as a full key path.  By example, if requested just 'summary.config.name' in such a manner, you acceding it starting from the host as object $_-> {'summary.config.name'}.

  You could easily improve the fortune above accessor method to check this possibility (I just eval the full path key, if that throws an exception, go through the list of keys as usual).

  It might help if you find a little frustrating to work with long anonymous hash references, nested.  I know I find it's ugly when I have to deal with many nested hash refs and validate each in the string is not undefined (destroyed by the SDK return).  I use similar accessor methods to avoid my code getting ugly for more complicated work of perl.
