• How to implement the ScreenUiEngineAttachedListener Interface?

  How to implement the ScreenUiEngineAttachedListener Interface? It is somewhat a mystery reading through the API.

  I have a class that implements ScreenUiEngineAttachedListener:

  public class UiListener implements ScreenUiEngineAttachedListener {
    public void onScreenUiEngineAttached(Screen screen, boolean attached) {
    }
  }
  

  Then I have a class MyScreen which extends from screen and has two methods:

  public void addScreenUiEngineAttachedListener(ScreenUiEngineAttachedListener listener) {
    super.addScreenUiEngineAttachedListener(listener);
  }
  
  private void removeScreenUiEngineAttachedListener() {
  
  }
  

  • What is the correct positioning of everything?
  • Can I define an instance of UiListener and pass in the addScreenUiEngineAttachedListener?
  • How to remove UiListener in removeScreenUiEngineAttachedListener?

  You will need:

  • an instance of your UiListener - probably a static member inside your UiApplication;
  • a method that allows to retrieve the reference to this instance of UiListener;
  • a call in your constructor for the screen at addScreenUiEngineAttachedListener (yourApplication.getUiListener ()) or similar;
  • potentially a call within your onScreenUiEngineAttached (attached screen, boolean) routine, the branch (attachment is false) : screen.removeScreenUiEngineAttachedListener (this);

  However, all this is too much work for no gain. Just override protected void onUiEngineAttached (boolean attached) in your screen class and make your logic there - all members of your class are accessible and all the code is placed where it belongs.

  Create a new virtual machine in Virtual Center - install the software updates that you need in this model etc etc.

  Click right of the virtual machine when you finished and chose "convert model', if you need later update it is again you can 'convert virtual machine' and update before make you a model again.

• How XAI implements the 'do more' function in CC & B pages

  Hi all
  There is a button "get more" in CC & B page if you put more than 50 recordings, just by clicking on the button when I want to get the latest recordings, but how do I implement the same function by XAI, I studied a lot of time on this problem and got nothing. so, everyone here had encounterd the same question? and resolved?
  any help would be appreciated.

  The GET more feature works in the browser because there is a separate servlet 'list' that retrievs data. It is based on some data to the HTTP context for correct operation. Unfortunately the 'do more' function is not supported by the Servlet XAI (it does not on the context HTTP data). Your only option is to roll your own mechnaism of paging for the data that you need.

  The model is going to like it...

  1. develop SQL code for what you want to paginate
  2. create a new "Listings Service" class that acts as a underlying service
  3 mark the service with entries include the size of the page and you want to retrieve the page number
  4. annotate the service with a list of data that will be returned
  5. use the page size and page number to create and run the query, and build the result
  6 enter the service as a Service of inbound XAI
  7. deploy the code
  8. test using dynamic presentation

  for example. Here is one more example for the search values...

• 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.

• How to implement the wafer map using LabVIEW?

  Hello LabVIEW Masters!

  I have a project which includes control and searching for information on a PROBER. One of the difficulties I have now is how to implement a WAFER card using LabVIEW. According to the requirements of my client, the element of pads varies between 6 k and 23 k. I guess that do everything (a = a ctl/indicator led) will be a hell of a task, especially on how to effectively manipulate each elements. Does anyone have a better idea on the way whose that?

  Please, I seriously need your help...

  Thank you and best regards,

  Hi Dennis,

  This wafer GerdW post card appears to me as a sort of histogram (for example http://www.ni.com/white-paper/4158/en#toc3);

  Altenbach post well this example that shows how to use a plot of intensity to create a 2d histogram:

• How to run the callback model SequenceFilePostStepFailure after step fails with the calls of the nested sequence

  Hello

  I want to appear a message immediately box on any test failure.  I thought I could use the reminder of the SequenceFilePostStepFailure model to achieve this, but when I change the reminder of process model to achieve this, I found that the recall code is executed only for the failures of step of the top level of the page sequence file.

  My test code has sequence called before mutiple files to the granularity of the basic numerical limit test that range from success or failure, so I would like to run the callback SequenceFilePostStepFailure immediately at this level.  I can accomplish this by adding a substitution of recall of SequenceFilePostStepFailure in the file of the sequence in question, but I prefer to use the implementation of reminder default template, so I can't find all the places where numerical limits tests are executed and cause the ASE of pass/fail.

  I have attached a few sequences of the example I want to illustrate the problem.

  Thanks for the help,

  Daniel

  My fault, I see now that the recall of model should I have changed is the ProcessModelPostStepFailure.  Problem solved.
