• definition programmatically switch Boolean so that a handler will act on this matter.

  Hello

  Is there a way to programmatically set a Boolean switch so that a handler will act on this matter? I use an interface developed by another group, with producer/consumer structure, as part of a validation of equipment. I want to create a separate vi that will control the GUI. Currently I can put the Boolean commands using an invoke node but the event handler does not react to them. My suspicion is that it's a mechanical action of Booleans. Is there a way to do this with to change the mechanical action?

  Pat

  Well, a switch is usually trigger (where the name!). You never said you try to use Boolean action latch.

  Yes, local variables and the properties of the value can not be used to lock the Boolean action because they are handed over to the State by default when terminal is read by the code, and if you would allow them to be read and put in several places, you generate a giant mess.

• Definition programmatically filter features

  In JDeveloper 11.1.2.3.0 I'll put the filterCriteria of a table programmatically.

  Now I'm trying to define the characteristics of filter as well, but I have not found a good documentation yet.

  What I've found so far is:

  Set featureSet = new HashSet();
  featureSet.add(query.FilterFeature.CASE_INSENSITIVE);
  Iterator criteriaIter = filterCriteria.keySet().iterator();
  Map<String, Set> featuresMap = new HashMap<String, Set>();
  while(criteriaIter != null && criteriaIter.hasNext()) {
       String keyCr = (String)criteriaIter.next();
       featuresMap.put(keyCr, featureSet);
  }
  query.setFilterFeatures(featuresMap);
  

  The code above gives me the following error messages:

  Line 2: Unexpected Type

  Line 9: Add casts to call "setFilterFeatures (Map).

  Any help is appreciated.

• Definition programmatically the menu item & quot; permit & quot;.

  I have a soft LOOK that offers a menu point which, when selected launches a dialog box.
  
  I need set the enabled property of the item of menu false after it is selected, that only one instance of this dialog box is expected to be launched, and I don't want to make the modal dialog box. I also need to set the property enabled to true when the dialog box is closed.
  
  I do this through the defaultDataDescriptor?
  
  BTW, the dialog box that starts is not a popup, it's in an AIR application in the main window, in what I call the 'activities '.

  I don't know if that's how I had to do, but I create an associative array object and when I disable a menu item in the ItemClick event (if it is a menu item that needs to be deactivated at the time), I store a reference to the menu item in the object. Then when I close the dialog box I have uses the reference to re - activate the menu item.

• Programmatically set the itemRenderer

  Hello

  How can I programmatically itemRenderers? The reason I need it is wanting the same list to change the rendering engines based on user input.

  I tried and it did not work:

  FirstItemRenderer extends IconItemRenderer

  var itemRenderer:FirstItemRenderer = new FirstItemRenderer();
  itemRenderer.iconWidth = 40;
  itemRenderer.iconScaleMode = "letterbox";
  itemRenderer.setStyle('iconDelay',0);

  data object contains properties name, icon, and Decorator; the last 2 are embedded resources
  itemRenderer.labelField = "name";
  itemRenderer.iconField = "icon";
  itemRenderer.decorator = "decorator";
  list.itemRenderer = itemRenderer as IFactory;
  list.dataProvider = acDataProvider;

  I tried and it works, but I can't figure out how to set what I could put on like iconWidth and iconField:

  list.itemRenderer = new ClassFactory (FirstItemRenderer);
  list.labelFunction = getName;
  list.dataProvider = acDataProvider;

  
  Where getName is:

  private void getNameitem:Object): String
  {
  If (Item.alternateName) {return item.alternateName ;}
  else {return item.firstName +' ' + item.lastName ;}}
  }

  Yet once again, I need this because if the user clicks on the button 1 then FirstItemRenderer is defined as the converter for #list, whereas if the second button is clicked, then SecondItemRenderer is set.

  Thank you.

  Discover the properties of ClassFactory:

  protected function assignRenderer(event:MouseEvent):void

  {

  var newRenderer:ClassFactory = new ClassFactory (MyRenderer);

  newRenderer.properties = {height: 100, alpha: 0.5};

  List1.itemRenderer = newRenderer;

• Definition of series R Analog Input Mode programmatic

  Hello

  I understand that the mode setting of analog input for 7854R series card can be made through the project manager (RIO Device setup)

  I would like to know if there is anyway we can do programmatically (as in the case of some cRIO modules HAVE).

  Thanks in advance for the help!

  Hey,.

  No, you can not change programmatically. Right under the RIO device installation program.

• The definition of dataProvider programmatically causes null reference

  I am trying to bind a drop-down list box to a list of countries via a HTTPService which returns xml code. If I set the dataProvider and declaratively labelField properties in the mxml, then it works fine. However, if I try to set it programmatically in the method that is called after the called HTTPService returns, then I get "TypeError: Error #1009: cannot access a property or method of a null object reference."
  
  Here is the dataServiceResult method:
  
  [Bindable]
  private var _lookupData:XML;
  
  public void dataServiceResult(event:ResultEvent):void
  {
  _lookupData = event.result as XML;
  
  cboCountry.dataProvider = _lookupData.countries.country;
  cboCountry.labelField = "@name";
  }
  
  This causes the above error. However, if I have the last two lines of the method in comment and change the combo box return to resemble what follows, then it works fine:
  
  < mx:ComboBox id = "cboCountry" styleName = "RequiredFieldLabel".
  dataProvider = "{_lookupData.countries.country}" labelField="@name" "
  change = "countrySelected ()" >
  < / mx:ComboBox >
  
  Any ideas? Declarative binding will work in this particular situation, but I have several other cases where I need binding programmatically to xml, so I need to get this script working. Thanks in advance for any help!
  
  Aaron

  The simplest way around this is to link the labelField and dataProvider to a variable or a get/set accessor, and then set the variables (or the Set accessor) in the result handler.

  What is happening is that the combo box has not been instantiated in the place in which you try to set the values, so the null pointer.

• Definition of channel programmatically in max scale

  I'm trying to define a new scale for multiple channels in max. Currently, I have 8 channels to max and which could lead to 32. I need a way to define the balance for these with my program, I use the cDaq and pci-50xe acquisitions for now, everything is entered analog. Basically, I'm trying to write a program to do the balance for each channel, it should be fairly simple. I can't create all scales needed before running because there are too many different sensors. I want to do it this way, rather than creating a custom scale so that I can have multiple channels in the same task that all have different scales.

  Ah.  you're really talking about application "Calibration factors" to your specific sensors. right (sort of a poor man TEDS)?

  in this case, I use a scale of 'Master' "MyLoadCell" that defines the units and provides a "Nominal" scale and apply to the individual gain and offset each sensor via a scale property node.  You have several ways to store this information in your system.  Named MAX scales can work well in your case and the DAQmx > advanced > configuration scale palette offers two options to get these properties applied to the scale.

• need help in the definition of the input value of a field programmatically

  Hi, I have an input file and a command button in jdev 12.1.3 that work very well together. The files download to the server and get somewhere that I want it to be saved.

  I have this code to get the name of the file in a bean:

  UploadedFile myfile = this.getFile();
  String nomdefichier = myfile.getFilename();
  

  I would like to than the bean to save the contents of this variable to an input file for which the binding is #{bindings. IndicateurFiche.inputValue} for the validation to keep the name of the uploaded file in the database.

  When I bind my inputfield on indicateurFiche, my file is not upload more. If I put my input file of the variable defined in the bean, the file is downloaded, but the file name value is not saved

  How can I do for this situation?

• Change of LabVIEW VeriStand system definition

  Hi all

  I have a project where I need to be able to change the drawn in LabVIEW VeriStand system definition.  The project will use a LabVIEW user interface and I would like to be able to programmatically change of LabVIEW VeriStand system maps (unloading and loading mapping .txt files via LabVIEW System).

  It seems that the SystemDefinitionAPI contains the methods I need, but I can't figure out how to get a reference for VeriStand.SystemDefinitionAPI

  If there is an easier or simpler way to do this, please let me know.  Thanks for your help,

  Phil

  A bit more info that may be useful...

  The examples referenced by Jarrod contain a constructor .NET to create a file system definition by giving a name, description, creator, version, etc...  If you double-click on the node in the constructor it will bring up a dialog box that shows all the manufacturers of the SystemDefintion object.  You should see another manufacturer that only requires a string entry "nivssdfFile".  Use this constructor and provide a path to your nivssdf file to open your SysDef existing (instead of creating a new).

  Remember, you should always call the SaveSystemDefinitionFile method when you finish your changes to commit everything on the disc (such as demonstrated in the example).

• Adding custom device VS programmatically

  Hey everybody,

  So I was wondering if there is a way to programmatically add a custom to a homeless GUY in VeriStand device.  I have a program that runs through tricks of calibration and after it's done I want to automatically add a device tailored to the Homeless.  So far I found only a way to get an up-to-date list devices custom - cannot add a.

  Does anyone know how to do this?

  Thank you.

  I assume you are using the definition of system .NET API to change the homeless before deployment.

  In this case, there is a constructor for a custom device that takes the GUID of the homepage. Once that is done, use the AddCustomDevicemethod on the node CustomDevices of the Homeless.

  When you have the custom device reference .NET (the object) you can configure it with calls .NET as add channel/section and set properties. Although, given that most of the custom devices have initialization VI who made the most of it, you can call initialization VI, in fact if you want. To do this, get the NodeIDof the CustomDevice object and passing to the initialization of VI connector pane.

  I hope this helps!

• Programmatically formatting graphic mixed signals

  I am writing an FPGA application where I am acquiring data from a unit under test (USE). The PXI-7842R digitizes 3 groups of signals:

  1. an analog voltage monitor

  2. 5 digital signals connected to the analog inputs (limitation of the pinout of the connector) and converted into Boolean values

  3. 11 digital signals connected to the digital inputs

  That's a total of 1 analog and 16 digital inputs. I want to show them on the same graph, so I used a graph of mixed signals.

  To avoid reconfiguring the graph of mixed signals, everytime I open the app, I wrote a Subvi to programmatically format the chart. I pass a reference to the graphic indicator of mixed signals and try to adapt it to look how I want. The indicator has been designed as a cluster of analog waveform 1, 2 bus waveform Digital 5 signals 1 waveforms digital bus 3 and 3 different digital waveforms. The Subvi is called inside the host VI using a statement box controlled by the 'First Call' function. Then host vi bed a U32 to the target-to-Host DMA FIFO, formats the data in the correct order and the beams while an indicator of mixed signals. During an attempt to format the chart programmatically, I get errors in property not valid which seem to depend on State. Unfortunately, the documentation of the properties seems to be quite uneven for errors I get. The Subvi attached through the following sequence:

  1. configure the shared axis and shared properties (IgnoreAttributes, ShowBusseswithLines)

  2 set up the area of tracing analog scale Y (superior plot, area 0? documentation is inconsistent on this point)

  3 set up the area of tracing digital scale (sector 1) Y?

  4. name the digital bus (3 in total, should be numbered 0-2).

  5 name the plots

  Correctly all steps 1 through 3, but I get an error when you try to set the Active Bus to 0--> ' #1077 Error, invalid property (Bus Active)»

  I tried to set the Active plot area to 1 before setting the bus, and I get the same error.

  But then sometimes if I rerun the VI host without change, the Subvi ends correctly (even if the area of the scale becomes huge and empty). The only way I can remove the errors is to set the for loops to iterate 0 times, allow the host VI run a few cycles, stop the host VI, remove the constants 0 and run again. And then there is no property errors.

  I then tried to create a constant of mixed signals with the correct sequence of the empty slots and it allows to set the MixedGraph::Value property at the beginning of the Subvi. Now error #1077 occurs at the level of the active node before Plot Bus Active node. The thing first on the definition of the constants of iteration 0 does not help when the value property is an initial value.

  Here are my questions:

  1. the ActivePlotArea property must be configured to use ActivePlots or ActiveBusses, or is that only for sizing and moving areas of land?

  2 - is ActiveBus ActivePlot to define first of all necessary to property? for example, if I have ActivePlot = 0 (for analog plot), the ActiveBus property will always fail?

  3. what else is necessary for the property ActiveBus of function call?

  4. why the Subvi is failing the first time but succeed during subsequent calls without be initialized does not yet reach every time after you initialize (except for loops are set to 0 and Subvi finishes once)?

  5. because I show a legend of the plot, I don't want the names of digital signal appears again in the scale box Y. How can I hide the names but to allow the plot area to extend completely to the legend of the plot rather than leave a large area of wasted white space?

  Hi Nick,

  The reason your Subvi does not work, it's the bus you want to change do not exist when you run.

  If you want to run this sub - VI like initializer, you must first initialize all of the plots you will be change.

  I've included a small example of how to achieve this by grouping together a constant of analog waveform with some constants of digital waveforms and food nerd in the property "value" Mixed Signal curve.

  

• Programmatically determine the PCI device ID

  Hello again all you lovers forum useful!

  I am writing an application for exit to and read entry from ARINC PCI card, specifically the ICAN-530 of GE Intelligent Platforms.  Now their LabVIEW drivers and the documentation is pretty good, but one of the things that I have a problem with is how to determine the ID of the Board of Directors.

  The documentation on this Board ID is marked "for PCI devices, this Council number must match the device ID assigned when the installation of the API and the corresponding device has been installed."  I'm sure that I have discovered this using MAX, but what I really want is to determine if the laptop running my application has this card special in it ARINC and if so what is its device ID, by any program without the user to select or install MAX, etc.

  I hope it's doable, but I failed to find the right screw looking through this forum and in the pallets of LabVIEW.  If someone could point me in the right direction (or definitely state that it can be done programmatically), I would be very grateful.  :-)

  Thanks in advance!

  -Joe

  Just in case where someone else finds this useful thread in the future, I got the following response from GE Intelligent Platforms (who I bought the card), that indicates there will be a relatively simple way to reach my goal by using the LabVIEW drivers.  I have not tried so I can't guarantee its effectiveness, but it sounds good.  :-)

  If the only GE avionics installed is the ICAN-530, he would have no problem invoking AR_Board_Init until you encounter a status of passage; However, if there are other cards installed AND the distribution of the CIS - x 30 - SW is installed on this host, there is a mechanism to check room types.

  The AR_Query_Device of VI VI provided in CIS - LV Version 4.10 (latest version and probably the one would have received you if purchased with the ICAN-530), can be used in the following sequence to check such allocation device number on your system without actually opening a session and during the initialization of the Council.

  (1) call AR_LoadDLL.vi with the set control system Type to be 'CIS - x 30'.

  (2) call AR_Query_Device.vi in a loop (BoardIDIn control incrementing from 0 to 15) until the indicator of Type of card is returned in 26 (type for ICAN-530) AND the errorOut.code '1 '.  The BoardIDOut indicator will be the Deviceid for the ICAN-530.  Council for the VI types are described in the online documentation and printed for CIS - LV live.

  (3) If you will be running your application, you can just go forward on the basis of the VI AR_LoadSlv and waive AR_Board_Init (as AR_Board_Init is just a combination of AR_LoadDLL and AR_LoadSlv).

  (4) If you plan on using it to work with any other type of Council other than a CIS - x 30 Board, you must call AR_UnloadDll.vi to remove the library API CIS - x 30 memory.

• Programmatically determine the default value of control

  Hello

  I'm trying to understand a reasonably sustainable method to detect if the sub VI input is wired.

  I use the approach to the definition of an absurd default for the control, and then by comparing the current value of the control to a constant of this value. If they are not equal, so I pass the value of the control in my registry to offset. If they are equal, I hold that any value has been previously in the shift register. In this case, I created a driving force that allows me to update the status bar.

  It works because my progress meter is a U8 I'll never write 0-100, so I can set my default to something outside this range (in this case, 255) for my comparison. Something similar should be relatively simple to understand and reuse in the future.

  However, there is a dependency on a person if the default value for the control and the update of the constant comparison to match. My question: is there a method to check the default value for a control programmatically in order to remove the coupling? I realize that any method would be invariably slower with regard to execution, but it's simply out of curiosity.

  

  I think that this method is reasonably justifiable if you document correctly and it works for me. Other developers do not tend to change the default values of the controls without reason.

  That said, the Control class has a default property, but I think it's private and it may not work when you generate an EXE file.

  If you want something that is more explicit, you can build a polymorphous VI - have one version of the VI with the entrance and the other without. The main problem is that users may not know that the entrance is there for them to wire without looking at instances of the polyVI, so I still prefer the method of the invalid value.
