JSON Date Source

• Web service JSON data do not return does not

  I created an application with a test sample local (active forlder) json file called "contacts.json" as below, just to test if I have any return data. The data returned in a listview without problem.

  [{ "id":1, "firstname": "Mike", "lastname": "Chepesky", "title": "Sr. Editor",
    "image": "images/data/mike_chepesky.png", "active": true, "gender": "m" },
  { "id":2, "firstname": "Westlee", "lastname": "Barichak", "title": "Talent Scout",
    "image": "images/data/westlee_barichak.png", "active": true, "gender": "m" }]
  

  I then changed the source for 'http://... '. "a link is valid and I checked, and it returns the data in a classic web browser (firefox). But he won't be in my application.

  What I noticed, is that the difference between the local json file and the return of web service, the web service does not return the square brackets "[...]" the json... I suspect that maybe that's the problem? If so, how do I manipulate the data source in my application to incorporate media? Is the returned data (without brackets) real...

  {"status":"successful","current_version":"1.1.1","latest_version":"1.2.0.0","details":"1. Item A 2. Item B 3. Item C","type":"Force update"}
  

  Thank you.

  If I'm not wrong, your local file json contains an array of objects, and that you load from your server contains a single object.
  If so, you can not call insertList (data), use insert (data)

• Display images using URLS from a data source

  Hello!

  I have a source of JSON data with a URL pointing to the image. Basically, each record is a description of the dish and lead to URL of image with floor etc. plan...

  How much control should I use to view these images? I tried

  -IFrame, but it does not display the Referrer attribute.

  -Result: a list, but it can only attribute as a URL parameter. If I have {0} for full URL it does not display anything

  Basically, I want to refer to the IFrame URL attribute. It's an obvious thing and simplest

  Any ideas?

  Kirill

  Answer:

  Oracle® short Information Discovery Studio: Studio user's Guide

  Page 205

  3. use only one attribute for the full URL, but that data ingest processes encode any non structural

  parts of the URL, such as query string parameters.

  This prevents script injection and addresses all characters that are not allowed. When you enter the URL, you can then use the value of the attribute without encoding more far. For example:

  {{0}}

  0 is a number in the list of selected parameters.

• DeserializeJSON - is there a limit on the size of the JSON data that can be converted?

  , I have a few valid JSON data which are converted successfully by DeserializeJSON... until it gets to a certain size, or is certainly what seems to be the case.  The breaking point seems to be somewhere in the neighborhood of 35 000 characters... about 35 KB.  When the conversion fails, it fails with a "JSON parsing failure: unexpected end of the JSON string" message.  And if the conversion fails, the JSON data are deemed to be valid by tools like this: http://www.freeformatter.com/json-validator.html.

  So, is there a limit on the size of JSON data can be converted by DeserializeJSON?

  Thank you!

  Thank you, Carl.

  The JSON is presented in its entirety, confirmed by Fiddler.  And it is in fact being recorded successfully to a SQL Server nvarchar field too.  I can validate that saved JSON.

  I'm actually grabbing the JSON to convert directly from SQL Server and your comments / ideas drove me on the path of resolution.

  It turns out that the JSON is truncated before going to the DeserializeJSON command, but it was the attraction of cfquery which was truncated.  The difficulty was to allow the 'long text retrieval (CLOB)"for this data source in CF Admin.  I would never forward or even knew that he had this setting.

  Thanks again for your comments!

• How to bind the data source to a custom class?

  Hi all.

  I use the chart control to draw two types of plots. One is a path of spectrum which refreshes all samples in a short time, and the other is a curve of time series which add than one sample of each time.  A chartcollection was related to the data source, however, and draw the spectrum seems to not cool off very quickly. Was it due to the propertychanged event? In order to improve the speed of response, what should I do to deal with the data source?

  I went through your response and the help files and found I made a stupid mistake - I always used to Append method (double, double) and did not notice its format void Append (list, list).

  Thanks for your patient response, Paul :-)

• create the SQL server programmatially data source

  Hello

  I would like to create a SQL server by programming in LabVIEW data source. The SQL server version that I used is from 2005. Can someone give some ideas? An example of code will be more favorable.

  Thank you

  You can build the connection string you even.  The open function in the Toolbox of data base accepts a string as well (it's polymorphic) who can be the connection string.  This is the site I use to understand.  Is the most common things.  You may need to search Google more specific elements.

  http://www.ConnectionStrings.com/

  If you want to use the other option, someone has achieved a UDL editor in LabVIEW.  You can use this code to create your own UDL which can use the Open DB function:

  I have used the above code, so can't comment on that.

• Logging data source expressions

  Hello

  We use NI TestStand 2012 here in our society, and I have a simple question.

  In any test pass/fail (numeric, String, pass/fail regular), is it possible to have the TestStand to include the data source expression in the default report?

  I can add it manually in the component "Other results", but I have to do for each step.

  I see that on conditional expressions and flow measures are included in the report, but not the my expressions of pass/fail, which are found in the data source tab.

  It seems obvious to me that the data source should be there, otherwise I just in the report the name of the step and the result and no information of what has been actually tested.

  Thank you in advance!

  Leandro

  It does not show what the '10' value means: speed, voltage, current, RPM, etc. unless we call actually step in this way.

  Thanks again.

  There is a 'units' set numerical limit markets which addresses this problem. You can even specify custom units if you would like, although there are many built in those you choose as well. Also the name of the step should usually give an idea of what exactly is being tested.

  For the recording of Boolean expressions, probably the simplest thing is to use a stage model that is preconfigured to connect to the data source, or you can create a new custom step based on the test of success/failure that connects to the default data source type, or you could write a tool that passes through the sequence files and change all tests pass/fail to connect their datasource.

• Report Builder 1.0 will not connect to the data source for Reporting SERVICES

  We have a few users who are unable to connect to SSRS on SQL Server 2008 using the Report Builder version 1.0

  (We will be updating soon, but it's a slow process, and now users have questions)

  Instead of disputed for their IDs, they are requested to select a data source.  This information is supposed to be filled automatically when the user starts the Reporting SERVICES report designer.

  Does anyone know where/how SSRS communicates information to start the application with one click Report Builder, and where, if anywhere, it stores?

• SSRS for lack of outer join with the Oracle data source

  It seems to be a problem with the Oracle driver used in the Reporting SERVICES query designer.

  When you use an Oracle data source, if I create an outer join in the graphic designer, it automatically inserts '{OJ' before the join and '} ' after her.  This is an incorrect syntax for Oracle and refuses to start.  The curly braces and the JO editable in designer text, but if I go back to the graphic designer and immediately to reintegrate them.

  Only, this has started to happen a year or two ago - before that it worked, but with the old (+) syntax.

  Can it not be healed?  It makes things very difficult.

  The only differences are: code is pasted in the {} instead of {Page} tab, and of course, the name of the database, the columns are changed.

  I added bb.data 1.0 import statement in the file .qml, the .pro file was also changed according to the tutorial. Path to the database file is correct.

                  allListsSource.load();
              }
          }
  

  New screen grows without any problem after clicking on list items. But when I add the following lines to listPreview.qml, application stucks selection list item and nothing happens.

  Page {
  
      content: ListView {

                      title: ListItemData.article_name
                  }
              }
          ]
      }
  
      attachedObjects: [
          GroupDataModel {
              id: dataModel
          },
          DataSource {
              id: dataSource
  
              source: "database.db"
              query: "select * from articles"
  
              onDataLoaded: {
                  dataModel.insertList(data);
              }
          }
      ]
  
      onCreationCompleted: {
          dataSource.load();
      }
  }
  

  It looks like I can not query the DB for the second time commenting on the DataSource {...} of listPreview.qml pushed the new app screen without any problems.

  EDIT:

  a simple solution: I forgot to add the statement import bb.data 1.0 in listPreview.qml

• QNetworkReply running into the problem of loading JSON data

  Hello

  I am a beginner with C++ and QT, but so far I'm starting to love the NDK waterfall!

  I'm trying to load a json data file that is extracted via a http request. Everything goes through, but my json data simply would not load in the QVariantList. So after a few hours of poking arround, I noticed finally that the json returned by the http request data is missing two brackets [] (an @ beginning and an end @).

  When I load the json data into a file with the two brakets included, the QVariantList load properly and I can debug through the records...

  Now my question is... how C++ can I add those parentheses []... See the code example below:

  void MyJSONReadClass::httpFinished()
  {
    JsonDataAccess jda;
    QVariantList myDataList;
  
    if (mReply->error() == QNetworkReply::NoError)
    {
      // Load the data using the reply QIODevice.
      qDebug() << mReply;
      myDataList = jda.load(mReply).value();
    }
    else
    {
      // Handle error
    }
  
    if (jda.hasError())
    {
      bb::data::DataAccessError error = jda.error();
      qDebug() << "JSON loading error: " << error.errorType() << ": "
          << error.errorMessage();
      return;
    }
  
    loadData(myDataList);
  
    // The reply is not needed now so we call deleteLater() function since we are in a slot.
    mReply->deleteLater();
  }
  

  Also, I would have thought that the jda.hasError () have captured this question... but guess not!

  I use the wrong approach or wrong classes? The basic example used is the WeatherGuesser project.

  Thanks for your help...

  It is perhaps not related to media. Try to recover data from QNetworkResponse as a QByteArray then load it into JsonDataAccess using loadFromBuffer:

   myDataList = jda.loadFromBuffer(mReply.readAll()).value();
  

  If this is insufficient, you can add media in this way (not tested, please see the documentation for the names of functioning if it won't compile):

  QByteArray a = mReply.readAll();
  a.insert(0, '[');
  a.append(']');
  myDataList = jda.loadFromBuffer(a).value();
  

  Note that if the response data are zero end (most likely it is not, but there is a possibility of it), you will need to check if the last symbol in byte array is '\0' and insert the capture media.

  QByteArray docs:
