• 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

  Jane

  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.

• [Microsoft] [ODBC driver manager] Data Source name not found and no driver by default specified

  Hi team,

  I am trying to connect to the Oracle 9i database using VB code below:

  strConnection = "Driver = {Microsoft ODBC for Oracle};" Server = SERVERNAME; UID = username; Pwd = PASSWORD"
  Connect = New ADODB. Connection
  Connect.Open (strConnection)

  The last line throws me below error:

  [Microsoft] [ODBC driver manager] Data Source name not found and no driver by default specified

  The VB code works well and able to connect to database server dev dev. The same script with the name of the UAT server does not work on server UAT.

  The servers are Windows server 2007-32 bit.

  When I checked the tab drivers in ODBC Data Source Administrator, dev server entry below:

  Microsoft ODBC for Oracle - 6.00.6001.18000 - Microsoft Corporation - MSORCL32.dll - Date

  Considering that the UAT server has entered below:

  Microsoft ODBC for Oracle-

  The Microsoft ODBC driver for oracle is listed in the tab UAT Server drivers, but did not have details of file version & dll. This driver is not installed correctly? If so, how the re install? Please help solve this problem as soon as POSSIBLE.

• 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.

  You have an idea, why this is happening?

                      var page = listPage.createObject();

              }
  
              attachedObjects: [
                  ComponentDefinition {

                      source: "listPreview.qml"
                  },
                  GroupDataModel {
                      id: allListsModel

                      sortingKeys: ["list_name"]

                  DataSource {
                      id: allListsSource
  
                      source: "database.db"
                      query: "select * from lists"
  
                      onDataLoaded: {
                          allListsModel.insertList(data);
                      }
                  }
              ]
  
              onCreationCompleted: {
                  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 {
          id: myListView
  
          dataModel: dataModel
  
          listItemComponents: [
              ListItemComponent {
                  type: "item"
  
                  StandardListItem {
                      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

• "BOLD" is supported by two streams of source with data source?

  I created a data source with two streams of source - one for audio and one for video. During the init data source, the streams of the two sources are created. When dataSource.start () is called, my application call start() of the two source Brooks.  When the player calls getStreams(), the soft returns an array containing the two water courses.

  However, once started, the player only calls the first stream's read() method. In other words, the read() method second flow is never called.

  Are several stream source by source of data supported by RIM, in particular on "BOLD"? I tested on v4.6.0.304 9000 "BOLD".

  Thanks for your thoughts/aid.

  It is not supported.

• Impossible to get two SourceStreams work for a data source

  The player does not seem to automatically use all SourceStreams provided by a given data source. I have two that are available through the DataSource #getStreams () function:

  * Video H264

  * AAC audio

  Only the first SourceStream is read in. Is there something special that needs to be defined or added to make all both get used?

  Yes, the implementation of the RIM does not follow the spec of J2ME and the javadoc. A single SourceStream is supported and the rest are ignored. It comes from someone on the EDGE.

• Fill the drop-down list in the SQL data source

  I have a data source that retrieves data from an sqlite database. How do I pass two areas of this query to a drop-down list on the page. I want to create a drop down list with the value and the text of this data source

  Hello

  To extract the values you need to wait for onDataLoaded. "data" parameter is a list of cards.

  An example of code for data access :

  To add an option to the menu drop-down:

  attachedObjects: [
    ComponentDefinition {
      id: optionFactory
      Option {

    }
  ]
  
  ... to add an option:
  
  var newOption = optionFactory.createObject()
  newOption.text = 'Text to add' // or a variable fetched from data source//newOption.otherfields = ...
  dropdownId.add(newOption);
  

• ODBC Data Source Administrator crashes

  Hi all

  I have a user in my body undergoing a crash in ODBC Data Source Administrator when he clicks on the file DSN tab. The mouse cursor changes to "busy" and will remain that way, at least that force us to close the program. While the cursor stays that way in the ODBC Data Source Administrator, the user is able to run other programs and otherwise working normally. This happens with the version 32 and 64 bit.

  Any help here at all is appreciated.

  Thank you.

  I have the solution. Microsoft has released a fix for ole32.dll causing programs to crash. Information and download link are available here:
