• Structure of the event run only on first change of the value

  Hi all

  I would like to a structure of the event to run only on the first change of value. I currently put to run on the change in the value of a Boolean value. I'm only interested in what happens the first time that the Boolean value changes; However, he changes several times during a single run of my vi. Is it possible to limit the structure of the event so that it runs only on the first change of value? I have attached the relevant part of my VI. Thank you in advance for any help, you will be able to provide.

  Thank you

• How the change in the value of the slider once out of the mouse in response

  Hi all

  When I used the slide bar to control my device, I answer the value change of slide bar and set the new value on my device. But it will generate the answer constantly when I use the mouse to drag the pointer, which is not my. I just need answer only after the mouse exit. How can I implement this feature?

  Hope your suggestion, thanks a lot.

  Use 2 separate controls instead of the digital screen on the slider.

  For a mouse event on the cursor, update the value of the digital control and do whatever it is you need to do.

  For a change in the value of the digital control, update the value of the slider and do whatever it is that you need to do.

• Monitor changes in the value of a variable in a module of code labview TestStand?

  Hi all

  A code in Labview module called from an action step has a particular variable that changes its value when running vi. Is it possible to monitor these changes through for example a local variable in TestStand and display different values on UI in real time via UIMessages?

  Thank you very much!

  You must post a UIMessage during execution of your VI.  As the following picture below, you can ignore the SequenceErrorMessage string and use the value of your variable as the numericDataParam.   I guess the trick is to determine where to display the user interface of Message, in your case, the variable updated at certain times or it he constantly updated?  I'm not sure of the performance LAG if at all times you post a UIMessage say every 100ms.

  

  On the other end, you will need in your interface user create a reminder of the Interface to manage the UIMessage.  See the following link for more details.

• Using time events only to trigger changes in the value

  Hello. I have experience with LabVIEW, but not a lot of experience with the structures of the event. Here's my situation:

  Let's say I have an entry, X, which comes from an external source. X is essentially random, from-100 to 100. My output will be Y, which will be generated by labview.  I want to have an initial value of 0. The first time that X is greater than 10, I want to change to 1 and stay 1 thereafter, until the first time that X becomes greater than 20. The first time that X is greater than 20, I want to spend at 2, and stay to 2 for always regardless of X, until the program ends.

  Basically the program will constantly samples X, and when X reaches a certain threshold, it will change and maintain the value of Y until the next threshold is reached.

  Any help is appreciated.

• Detect the change of the value in While loop

  Hello

  I recently took a code example in examples of using Labview and I'm putting the analog output through my data acquisition card 4461 pxi. I want to have a continuous waveform, but being able to change the volume and the waveform will adjust automatically and be issued through the card.

  In the code, I have everything first to open a .wav file and write it. While playing continuously through the while loop, but I want the signal to change automatically when the volume is changed. I know that I should probably use a structure of the event but the while loop, I use to play the signal will never stop unless the user presses stop so it would play permanently in a structure of the event even when the value changes (I tried).

  So now I try to see if there is a way to make my time stop loop when the volume value.

  You must correct the issues (forget the events if you are not sure of them):

  1. If wire you the digital volume to the wall of the while structure, then the whole in structure only tell that one value that happens on the node and will not read new values.

  2. to read the new values, move the Volume Terminal inside any building (which will shock your other code that depends on it), or use a local Variable inside any node.

  3. to check if the value has changed, you must compare the value to the previous value. To do this, use a shift on the while loop register to store the previous value and then compare it to the new value with the function "not equal?". Wire the Boolean result of this to the conditional Terminal.

  A better way for you might be to wrap the multiplication and Analog Write function into the while loop so that you're constantly replaying the waveform and it's continuously being re-scaled by the volume value. This will mean your volume control is being continuously polled (once per waveform playback) and used to scale the waveform each time. You'll need to figure out how to stop, send and play the waveform once per iteration of the while loop by bringing the Stop VI inside too. 
  

• ADF: color change of the value of the column according to the requirement

  Hello world
  
  I use Jdev 11 G.
  I have a column in the table pivot for example.
  If the value of the pivot is < 25 I need to change the color of Brown.
  If value pivot is between 25 and 1000i need change the color to green.
  If the value of the pivot is > 1000 I need to change the color to red.
  
  How can I achieve this?
  
  Please let me know your valuable suggestions.
  
  Thank you.

  You should use

  inlineStyle="#{cellData.dataValue gt 25 ? (cellData.dataValue gt 1000 ? 'background-color:red' : 'background-color:green') : 'background-color:brown' }">

• NEC Bind array Variable on changes in the value of SelectOneRadio

  I have a SelectOneRadio button and a Table. I just set the variable binding of the query that is displayed in the table of selection of option buttons.
  I put the buttons SelectOneRadio autosubmit true and I have a method to the ValueChangeListener destination. In the ValueChangeListener I get the value of the SelectOneRadio and setNamedWhereClauseParam ("bindValue", value); I also added the Id of the SelectOneRadio to the partial relaxation of Tables.
  
  However the variable binding is still not updated. Y at - it a step I have missed to set the variable in the query binding when you press the SelectOneRadio, run the query and refresh the page so that the update query is displayed.
  
  I use JDeveloper 10.1.3

  Steve,

  You must select the id of the component, not the property of partialtriggers of selectoneradio selectoneradio. When you do this, the components selectoneradio id is 'sor1', then the partialTriggers property must be set to the value 'sor1', it won't lead to EL Expression just a literal value.

  Follow the steps below:

  -Select the table in the structure pane, in the property inspector, select property "partialTriggers".
  -In the menu, select 'Edit' (no generator expressions)
  -In ' change ownership: PartialTriggers dialog, select component selectoneradio and then move it to the selected and then say okay section
  -The id of the component of selectoneradio would be assigned to the property of table partialTriggers
  -To the source of the jspx page, it should be something like partialTriggers = "", if the radio id is sor1, it should be (partialTriggers = 'sor1')

• changes in the value of the text depending on whether you select value LOV

  for example, I have this list angoua, graig, manu... I select Clément... then a text will get a value such as "person" wrong or anything like that, I would like to put in an IF statement in accordance with the selected value of LOV

  Hello

  It's not good to treat angoua as a person wrong ;)

  You can write this code of the trigger KEY-LISTVAL of the element. assign the value to a piece of text in the trigger KEY-LISTVAL and LOV, make sure that the value and write the code accordingly.

  Kind regards

• Map effective, where the keys never change, but the values change frequently

  Hello

  I need to spend many independent data (DBL, pressure readings) autour points, and they must be accessible by name (channels) from different parts of my program. Rather than having a huge cluster of many elements, I thought using a card.

  My requirements are:

  • The keys are unchanged for the life of the program
  • Values change frequently and at the same time (currently 10 Hz, but it could grow to 100 Hz)
  • All the data is quite low)<100>

  What is the best way to store my data? https://decibel.NI.com/content/groups/large-LabVIEW-application-development/blog/2012/09/04/using-VA... Describes a table of effective correspondence. It seems optimized for fast retrieval of data; I don't know if this is it suitable for the storage of data fast and frequent.

  The 'best' way would be different if I had a large set of data (> 10 000 items)?

  Thank you!

  Less than 100 items with keys of the strings, use the variant attributes and call it a day. For the largest data sets, I'll use a hash of the bucket scheme. The first step maps the keys to one of a fixed number of buckets. Each segment is a Variant, and attributes are used to resolve collisions. I put in other systems that are faster, but there is a cost of complexity of code highly it is really only worth paying if you are curious or that you have a very demanding application. Variants are almost plug and play.

  Your other option would be a memory in the database like SQLite. Good API and enough speed for all but the most demanding applications.

• How to detect the change in the value of the point?

  Hi all

  We want the list of all the goods that the customer chooses, TileList is used to display all the information about the goods and a custom component MyItem is used as ItemRenderer. Meanwhile, a tag is used to display the sum of all the goods. The hierarchy is simply like this:

  <? XML version = "1.0" encoding = "utf-8"? >
  "< mx:Application xmlns:mx ="http://www.adobe.com/2006/mxml"layout ="absolute">"

  < mx:TileList id = "tl" dataProvider = "{acGoods}" ItemRenderer = "MyItem" / >

  < mx:Label id = "labelSum" / >
  < / mx:Application >

  Here, acGoods is an ArrayCollection collection which I believe may be linked.

  The user can change price in MyItem directly, so no need to update the text of the label as well. I find that acGoods contains the last price. Now the problem is the text of the label remains the same. I tried to call the calculation function in set acGoods(), but it does not work.

  Please don't not event expedition sugguest because this is a simplified scenario based on only. If someone tell me how to implement this in conjunction fluxhing, it'll be very useful.

  Best wishes

  protected function get totalLabelText (): string {}

  for each i: var * in acGoods and so on

  return 'label calculated here;

  }

  MyItem Inside:

  Once you've changed something to invoke:

  Application.application.executeBindings (true);

  Hope it will work for you

• You are looking for the change of the value set in a large set of records

  I have a table with hundreds of millions of records

  PERSON_ID,

  WEIGHT,

  DATE_TAKEN

  -It is possible that a person has a single folder ie weight was measured only once

  -It is possible that a person's weight was measured twice or more on a single date

  I need to get on a list of people (PERSON_IDs) that:

  1. at least one penny above certain trashhold ie TRASHHOLD1 = 100 kg; This can be hard-coded.

  2. and while the weight of the person of (1) dropped more TRASHHOLD2 then = 20 kg in any suite (must be later) measures

  I'll try to find the fastest possible solution using Oracle 11.x and in any client IE SQLDeveloper

  Just noticed your reply to Justin says times 1 & 2 must be selected. This means you want to threshol1 or more, rather than threshol1. My code should use > =: threshol1. The following corrected code:

  with t as)

  Select person_id,

  weight,

  case

  what weight > =: period1 - equal or more: statement1

  then (weight) min on)

  person_id partition

  order of date_taken

• Changes in the value of the property of Arc "Include in DDL Script" is not saved.

  I have arches in my design I want that code auto DDL will not be generated because FK are composed and the generated code for the validation of the CRA in these more complex cases is not correct, so I created an explicit constraint on the table for this validation.

  But the problem is that the property of Arc "Include in the DDL Script" is not being saved in the design.

  If I unchecked the option for CRA and generate or view a preview of the DDL code the CRA is not generated.

  But when I save the project, close and reopen the bows have this option turned on again.

  I've been checking files xml for arcs and this property is not included, then by default always generates.

  Thank you!

  This problem is corrected in Data Modeler version 4.0 EA3 which is now available for download.

• Dynamic region on the change from the drop-down list of values

  Hi Experts,

  Using the concept of dynamic region, I tried to use buttons as I have 4 buttons and clicking on each button, I am loading the particular taskflow. I used setPropertyListener and type = action to achieve this.

  I have a similar requirement, but I need to use the drop down list here...

  < af:selectOneChoice value = "#{mybean.value}" >

  < f: selectItem itemLabel = "First" Valeurelement = "FirstValue" / > "

  < f: selectItem itemLabel = "Second" Valeurelement = "SecondValue" / > "

  < f: selectItem itemLabel = "Third" Valeurelement = "ThirdValue" / > "

  < f: selectItem itemLabel = "fourth" Valeurelement = "FourthValue" / > "

  < / af:selectOneChoice >

  How can I dynamically load a region on the value selected by the user on top of the data. On the change of the value in the drop-down list, I need to load this particular dynamic region

  JDeveloper version 12.1.3

  Thanks in advance.

  You use a listener to change value of the duo down and detect the region according to the new value of the duo down.
