• 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

• value chain control event does not trigger change

  Hello

  I am trying to scan a barcode with a barcode usb HID scanner. I use a structure of the event to detect the change in the value of a control of the chain. When I scan the barcode, the chain control updates on the front panel, but the event does not fire until I left on my mouse on the front panel. can someone help? See attached vi

  Your barcodes are probably fixed length. When you get an event, check the length. If it corresponds to the length of the barcode, then process the data, otherwise wait for more characters.  This can be treated very quickly in the case of the event.

  Hi amcop4591,

  1. How is - that Mount you the drive on the computer?

  2 Di you use any third-party tool to mount the drive?

  I suggest that you remove the external drive using the disk management and check back later if you can change the permissions on the drive.

  If you change the permissions, make changes to the permissions on the drive and then mount the drive.

• 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.

• Change "Verified the value" of a messageCheckBox

  Hi all
  
  How can I change "Verified the value" of a messageCheckBox?
  -----
  Used OAMessageCheckBoxBean = (OAMessageCheckBoxBean) webBean.findChildRecursive ("ItemReturned");
  
  If (poItemId == 'Y') {}
  Value of verified value Y
  } else {}
  the verified value W
  }
  -----
  
  I tried the choiceR.setValue("W") and the choiceR.setDefaultValue ("W"), but they are not to set the checked value property I believe.

  Nadir,

  Just the true or false value based on what your value of checkbox will be checked and unchecked and will return the value you defined in your property window.

  If you want to change your valuable W with another value, then you can try to use
  setTrueValueObject (NewValue) method on the instance of OAMessageCheckBoxBean.

  Kind regards

• List drop-down selection trigger change in the text field

  I'm hit a roadblock here. I'm on Adobe Acrobat XI and here's the scenario: I have a list box and a text box.

  Drop-down menu field has 3 caps (A, B, C).

  If A is selected, the text box = 15 default, but has the ability to change in the text box.

  If B or C is selected, the text box = 0 or "by default, but it has the ability to change in the text box.

  If I use an if/then with a .value, I'll be able to get the numbers to work, but do not have the ability to edit and keep them there. If I enter another number in another area, the JavaScript code will run and change the text box to 0 or 15.

  Any help would be greatly appreciated.

  Thank you

  Instead to use script logic for the text field, use the drop-down validation script. In this way, that it only will be triggered when you change the value in the drop-down list field, not when you change any field in the file (as the calculation script).

• I need to use programming like ActionScript loop, trigger, and load the data in the movies.  I can do with AE?

  I have been producing auto generate and parameter based animations for an artist over the years using Flash.

  Like this: Zarah Hussain | Animation

  Someone asks now that we use After Effects, but I need to use programming like ActionScript loop, trigger and load data into the movies.

  I can do with AE?  We need the loading animation 3 data values that affect the colors in real time

  Is it: -.

  Flash = online and interactive

  AR = fixed and linear.

  Help!

  Cries.

  You cannot use AE for this kind of things. Outside very limited real-time EI functionality it has not yet officially a dynamic performance of preload beyond the evalFile() hack. None of this makes no sense at all.

• 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. 
  

• 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.

• 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')
