• What I need to install in another pc without LabView and wants use executable Vi

  Hi, everyone, please, help me

  I want to use another VI without LabVIEW PC executable, what I have to do to run the VI.exe?

  Thank you

  At a minimum, you will need to install the LabVIEW runtime engine.

  You may need to install more depending on what your program does.  Maybe the drivers DAQmx or the VISA run-time.

• Acquire GigE camera data using labview CIN or DLL to call.

  I am tring to acquire data from a basler runner line CCD camera (GigE).

  Because the NI Vision Development Module is not free, and the camera provide a C++ API and C and also some examples, so I plan on using the function CIN or call DLLS in labview to achieve. Is this possible?

  I tried to generate a DLL with the example of the company code of the camera. But encounter difficulties;

  I did that a little background in C++, but not familiar with it. The C++ Code example provides the camera is a C++ (a source Code file) and a .cproj file, it depends on other files, the camera API directory.

  If I build the project directly, it will create an application window, not in a DLL. I don't know how to convert a DLL project, given that other information such as dependence in the .cproj file, other than source code.

  Can someone help me with this?

  Don't forget that for the acquisition of a GigE camera, you must only Module of Acquisition of Vision, not the entire Vision Development Module. Acquisition of vision is much lower price and also delivered free with hardware NI Vision current (for example a card PCIe - 8231 GigE Vision of purchase). You need only Vision Development Module if you then want to use pre-made image processing duties. If you are just display, save images to disk, or image processing using your own code (for example to manipulate the pixels of the image in a table) you can do so with just Vision Acquisition.

  It is certainly possible to call DLL functions if LabVIEW by using a node called library, it would be quite a lot of work unless you are very familiar with C/C++. Since their driver interface is C++, you need to create wrapper functions in C in a DLL that you write. Depending on how much you want to expose functions, this could be a bit of work.

• API in LabVIEW VeriStand using for graphics

  Hello

  I was wondering if anyone has experience reproducing graphics that accompany the VeriStand workspace in LabVIEW via the API. For example, should I use the block to get the value of channel to power a LabVIEW graph or is there another suggested method? Thank you.

  You can start by this example:

  \examples\Execution API\UDP Streaming\UDP Example.vi streaming

  It shows you how to request data in continuous high-speed gateway VeriStand and treat it. It does not show another specific feature of the graph VeriStand workspace, as the locking button, but it's a start.

Someone help me please

  Hi SumiSadiq,

  I received your MP, but it's a bit hectic at work so I'll be back later for a good overview of your problem. First of all a suggestion: do not connect your signal to each request.

  I suggest you train your code as my code or paste your code everything about the network (I do not see the QNetworkAccessManager built anywhere for example).

  My sample code (based on the code of ToodleTen):

  void DeletedTaskAPI::getDeletedTasks(int modAfter)
  {
      QUrl url("http://api.toodledo.com/2/tasks/deleted.php");
      //Prepare parameters
      QUrl params;
      params.addQueryItem("key", Information::getSessionToken());
      params.addQueryItem("after", QString::number(modAfter));
      params.addQueryItem("f", "xml");
      QByteArray data;
      data = params.encodedQuery();
      //Prepare request
      QNetworkRequest request;
      request.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");
      request.setUrl(url);
      //Execute request
      networkManager->post(request, data);
  }
  
  void DeletedTaskAPI::networkFinishedSlot(QNetworkReply* reply)
  {
      if(reply->error() == QNetworkReply::NoError)
      {
          QString xmlReply = QString::fromUtf8(reply->readAll());
          qDebug() << xmlReply;
          //Process data here
      }
      else
      {
          NetworkErrorHandler::getInstance()->processNetworkError(reply->error());
      }
  }
  
  /**
   * Constructor & Destructor
   */
  DeletedTaskAPI::DeletedTaskAPI()
  {
      networkManager = new QNetworkAccessManager();
      connect(networkManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(networkFinishedSlot(QNetworkReply*)));
  }
  
  DeletedTaskAPI::~DeletedTaskAPI()
  {
      delete networkManager;
  }
  

  NetworkErrorHandler is my custom class that reads the used API error codes and presents them in a nice dialog box to the user.

• What is the easiest way and automated to automatically remove data cards without using the API.

  We have a use case where you want to get a number of data cards in the last 30 days. I know that I can use the data card evaluator app to count, but not with additional limits to date created.  I was wondering if anyone has found a way to automatically remove data cards without using code API/custom just so I can get the correct number, I always desire or some other way to solve this puzzle.

  Thank you

  Amit Pandya

  OK never mind, just resolved using this day and form the connector to cloud, just a counter in the data card whenever a transaction occurs by product with combination of program generator.

  If anyone has any other simple approach, please share.

• Using Lab Manager API Java code example

  VMware or anyone have a sample code for using the API in Java? I mean, I have the host name, user name, password, I would not immediately be able to use the API to write my automation tools? spend hours finding the right pots, generating all these strains and write my own code (100 lines) just for connection resembles a maddness for me...

  After posting my original answer, I remembered that I had posted a code on this forum before. It's a stripped down version is about what would later become the LabMinder code I mentioned previously.

  If you go to the post office: Re: sample SOAP API for Lab Manager in necessary Java at December 20, 2007 by Michael Ottati you can retrieve the zip file in.

  1: change the world

  VMwareX0020LabX0020ManagerX0020SOAPX0020Interface to LabManagerX0020SOAPX0020Interface

  2: change the occurrence of:

• Adapter DLL: Name of the function change & params without unloading of the DLL

  Hello

  I use teststand adapters API to dynamically build a DLL call step. Each dll function is called through this subsequence "DLL Manager."

  Tried 2 methods (here is a summary of the code):

  1 ActiveX as follows:

  CommonCModule.ModulePath = myDllpath

  CommonCModule.FunctionName = myFunc (Note: this call unload the DLL previously loaded)

  Module-> LoadPrototype

  (to set the params)

  2 steps statement:

  RunState.Sequence.Main ["Call DLL function']. TS. SData.Call.LibPath = myDllpath

  RunState.Sequence.Main ["Call DLL function']. TS. SData.Call.Func = myFunc (Note: this is a step, but the info seems not be updated-online the new feature is called not properly)

  Module-> LoadPrototype

  (to set the params)

  The two methods is exactly the same behavior, but good for the 1st function I call a work or if I dump the dll after the execute step.

  However, is there a way to use these steps (or other) at stage configuration, but without unloading the DLL between each call. In my test sequence, I must OpenConnection with the object to be measured before starting my orders, as well as the dll should not be discharged to keep the connection open...

  for example

  (1) OpenConnection()-online this function takes the handle of communication with the device

  (2) myCommand1()

  (3) myCommand2()

  (4) CloseConnection()

  Thank you for the help

  C.

  If I understand your question, there are several ways to solve the problem. The easiest is to place a call to the dll before your loop that you never change programmatically. This step will then keep the loaded dll (if any stage that uses a dll is loaded, then the dll remains loaded. A dll is unloaded when all the steps that use it are unloaded.). Another option is to have just internally your call to the dll LoadLibrary on itself so that it is never unloaded. You then leave the process to unload the dll well. Another option is to add the code directly to the sequence that explicitly, charge and discharge your dll with the Win32 API LoadLibrary and FreeLibrary.

  That said, what you describe, if I understand correctly, looks like a very unusual use of TestStand. Looks like you use TestStand as a dll calling rather than as a sequencer and write your own sequencer above it instead. Have you thought to generate an entire sequence to run in teststand, rather than a step at a time? Basically, convert your test script in a TestStand sequence.

  Hope this helps,

• Add external Python DLL to the project setup

  Hi all

  I have a Setup program, but can't seem to add a python DLL. There's that VI s that use the DLL, but for some reason, the project does not add the python DLL. I tried to do the project > add to the project, but that allow you to add files randomly, just of Labview files. Not sure why it is so restrictive.

  Any help would be appreciated.

  Thank you

  I thought about it. If you go to work in the project that lists, right-click the add menu has more options. Cordially for someone else.

• Create Setup without labview

  Hello

  Is it possible to create an installer without LabVIEW? I'm supporting Windows 2000 to 7 and software versions of NEITHER varies with each OS, especially when dealing with Windows due to conflicts VISA oscilloscopes.

  The two main problems I have with the creation of installers with LabVIEW (Application Builder):

  1) Windows 2000 requires the framework produced prior to 2.8.0. It is therefore impossible for installers run on Windows 2000, requiring the installation of the product more recent than 2.8.0 which is basically each installation for Windows 7.

  (2) as far as I know, the software must be installed on a local computer first before you can create a Setup program. Then, you go to the section of additional installers creating a Setup program to add to the installation. The location path will point to the orignal CD drive or location it was installed from the local disk. I do not see why it needed. Why can the Installer be created directly from extracted files without it installed on the machine?

  Thank you

  Wow guys, thanks for the blatent insults two. If you have nothing nice to say don't say it at all.

  A little more explanation:

  Press and hold Windows 2000 in 2014, I agree, are heavy. However, you will need to make these oscilloscopes that are running Windows 2000 in 2014 still cost up to $8,000 to replace and the operating system cannot be upgraded. Why always cost so much? Because they are very useful tools. New and cost $ 20 000 to $30,000. I don't think that this effort is "los [ing] [the company's] ability to make a profit.

  I used SFX Builder (http://sourceforge.net/projects/s-zipsfxbuilder/) to group software NOR in a single executable file. Here are the steps:

  (1) download all necessary software OR

  (2) download SFX Builder

  (3) download 7 - zip (http://www.7-zip.org/)

  (1) extract all the software OR in a single folder and 7-zip can compress them into one archive .7z

  (2) open the SFX generator and adds the tab file from archive .7z

  (3) you can easily set the path of extraction anywhere on the computer, the temp (%temp%) is most useful

  (4) the tab tasks, click add/plus button and select program to run, and then enter the path where the extraction happened, here's an example

• Problem update the payload using the API of Services of Workflow task

  I have problems to update the part of the payload of a task by using the API of Services of Workflow (10.1.3) using the SOAP protocol. Try to use the setPayloadAsElementmethod, it seems, that the element of the payload is deleted rather than being defined.
  
  The purpose of the payload is constructed as follows:
  
  DocumentBuilder builder is DocumentBuilderFactory.newInstance () .newDocumentBuilder ();.
  Document document = builder.newDocument ();
  
  Support useful item = document.createElementNS ("http://xmlns.oracle.com/bpel/workflow/task", "payload");
  Child element = document.createElementNS ("http://xmlns.oracle.com/pcbpel/test/order", "command");
  payload.appendChild (child);
  
  The following lines are used to retrieve and update the subject of the task:
  
  IWorkflowContext context = getWorkflowContext (userId);
  Task task = taskQueryService.getTaskDetailsById (context, taskId);
  
  task.setPayloadAsElement (payload);
  taskService.updateTask (context, task);
  
  However, for some reason, it seems that the payload is not set correctly and in time updateTask is called on the TaskService object, payload of the task is not available. In turn, this causes an error when the SOAP request must be encoded (since the WorkflowTask schema requires a "payload" element).
  
  I run the code in a debugger and noticed that the the task object has a field nodeArray, which initially contains an element of payload. After the call to setPayloadAsElement has been run, no element of the payload is present in the field of the nodeArray and the mIsPayloadChanged field has been set to true.
  
  Code is taken almost directly from one [example in the documentation of the API: http://download.oracle.com/docs/cd/B31017_01/integrate.1013/b28985/oracle/bpel/services/workflow/task/model/TaskType.html#setPayloadAsElement_org_w3c_dom_Element _] and I'm completely lost as what to do differently. Could there be a problem with the way the Document object is built?
  
  Everyone knows about similar problems? Any guidance would be appreciated.
  
  See you soon,.
  Emil
  
  P.S. I also tried to spend in an element of payload without child element that does not work either.

  Hi Emil,

  Your code looks ok. However, I use the oracle.bpel.services.common.util.XMLUtil object to generate the document object.

  Document document = XMLUtil.createDocument ();

• How to read the counter NI9411 using C API data?

  I use the API C of NOR-DAQmx to read the data of a cDAQ-9188

  I am able to read analog voltages and entered digital fine (NI9201 and NI375).

  Problems with counters (frequency of measure) (NI9411).

  I just get error "all or part of your samples are not yet acquired" after the timeout.

  My pseudo-source:

  My device and any other names are correct?

  Thank you.

  Have you compared it against examples of api C?  I think that you have the option to install the examples when you install the daqmx drivers.

  If you have done this, and it looks the same then I would say you should try Troubleshooting If you produce any data at all.
