• "Argument mismatch in the property or function argument" on nodes.length

  Hello

  But I try to get on the nodes property length, I always get this error:

  "Inadequacy of argument in the property or function argument.

  It happens regardless of what level of the DOM/SOM I try, even if I can solve the nodes, values, etc..

  Here is an example that would lift the error:

      var objDataGroup = xfa.resolveNode("$data");

  xfa.host.messageBox (objDataGroup.nodes.length);

  What I am doing wrong?

  Thank you!

  Have you tried the below...

  Try the resolveNode on $record instead of $data.

  var objDataGroup = xfa.resolveNode ("$record");

  xfa.host.messageBox ("" + objDataGroup.nodes.length);

  Thank you

• Performance of the property as accessors for class nodes

  LV2013

  I vaguely remember reading somewhere that property nodes require a context LV switch because they must be run on the UI thread.

  • Is this always true?

  • Is true even if the node are not related to a user control (e.g., an accessor for a field of private data in a class)?

  • How much of a penalty that is? Everyone has ever measured it?

  • It is convenient to use a node property with terminals 2 + to access the fields 2 +.  Is - this comfort outweighs the drop in performance?

  • Are there any books or other documents explaining all this?

  Thank you

  That's only true property nodes that run in the user interface thread, such as those that refer to elements of façade. Executing an accessor LVOOP via a property node is just syntactic around a standard call from VI and don't force a switching of threads. I remember reading that there is a slight difference in this read accessors run always in the order due to management errors, but I can't find this post in a quick search.

• Element of cluster R/W by the property node

  I have a table via nodes of property by using the value property, but have not found a way to do the same thing with a cluster. Am I missing something?

  Ah yes. If you want to get an individual item then read the linked document Adnan Z. According to the title, this seems to be what you want to do, but body, it seemed that you wanted the entire cluster.

• the property of the graph XY value node labels problem

  Hello

  I have a XY Chart, and in coding, I have introduced into different clusters (cluster of two elements, each of them is a table 1 d).

  To sort the chart "remembers" the old data labels (data type, see background windows help), and I can just change it to the new.

  Let me explain better with this picture:

  

  The goal is to get the appropriate data type when I read data from the XY graph through the property node. I want to see 'curve' when I ungroup by name, not a former name of "DAC (V).

  Please don't tell me to delete this graph and create a new. This of course solved my problem, but I would like to know, how I can "force" a XYGraph change its names of data types...

  I've also attached a VI test to show this behavior...

  Suggestions?

  Thank you

  Kind regards

  Yes, it seems to keep outdated information. I was able to remedy to temporarily a table 1 d complex wiring to the terminal of the XY graph, then your cluster back wiring.

  

• The property node reference

  Hello guys,.

  Using the property node, I confused with the terminal of reference there. Can we establish a special reference to the control (button, for example), but obviouly I couldn't connect the button directly to the point of reference. I find an example about which attached in attachment. How can I creat something like that? So enjoy!

  Phyyu,

  VI server references follow the structure of object-oriented class. A VI server reference can refer to a wide range of objects, such as a control, etc. variable indicator, VI. Server of VI References can be as strict or not strictly typed as you wish. A control/light specifically made reference refers to a command that you pass to it. You can request to be more rigorous by right clicking on the reference, and using menus to select the class that you want to reference. A tree of possible class might look like this: Server VI > generic > G object > control > Array. Now this reference requires a pointer to a table control and will not accept any other type of control. If you use this reference control to create a property node, the properties will be specific to the array class.

  A refnum is simply a numeric value that refers to a place in memory. Reference and refnum are used somewhat interchangeably in LabVIEW.

  I hope that answers your questions! See the help files of LabVIEW for VI server references to learn more about them.

  Kind regards

• How to get the reference or the property of a member in OOP node?

  Hello world

  Is it possible to get the referral of a member in OOP?

  After you have created a class and an insert, a member of control in the cluster, I conclude that, when a right click on it, there is no element of "creat-> reference" or "create-> property node?

  So, how to get the reference or the property of a member in OOP node?

  Hello

  There are a few reasons that you can't do what you want to do:

  1 al ' LVOOP ordinary (as opposed to the DVRS in LabVIEW 2009, or some other framework / pattern design) are items of LabVIEW by value, as a cluster and therefore you can not create a reference to a class.

  2. a control of the object (this is what you get when you drop an object on a façade) is a 'black box' because you cannot look inside. This is to support the idea that the class data private. This means that you can't get a reference to all internal control when its on a façade

  3. check the references are valid only for the controls in the Panel before and therefore any class (or other piece of data of LabVIEW) on a wire / shift register / constant / anywhere other that of the façade, will have only the data portion of the available control.

  To access the items within a class, you create the accessor screws (you can create them easily by right-clicking a class (or the folder within the class) in the project tree and selecting New-> VI to access data members.) This VI would at least have a unbundle / bundle node (depending on whether its read/write) and could, if you have many more features such as range checking. You can use this VI whenever you want to read the Member your interested.

  I hope this helps.

• Display the property Node error 1077

  I created a vi with several analog inputs (up to 20), and I want to be able to turn on and off on the front panel plots. I currently have this case structure configured to go through each entry (i n), and the front (LED buttons) can be activated and deactivated to choose which plot to display:

  

  Turn work, the plots but I get this error message:

  1077 error has occurred to the property node (arg 1) in NetworkAnalyzer_UpdatedDAQmx.vi

  Possible reasons:

  LabVIEW: Value of property not valid.

  Property name: field Active

  All solutions? Thank you.

  Are you sure that the number of elements in the array of Boolean is the number of locations that you did? This error indicates that you have more items that you have drawn in your array of Boolean.

• position in the property node is not updated in another while loop

  Hello

  I have a structure of the event in a while loop and I have a chart with 2 sliders on it. the chart is in the loop outside the structure of the event and it becomes a wave form when an event occurs.

  in a separate loop, I have 2 cursors cursor position property. I subtracted to get their distance. but when I move the sliders on the chart which is in the first, while the loop doesnot change the values given by the property nodes in the second loop

  is this something related to the structure of the event? don't needs real graphic to be updated all the time or is it ok if she becomes a waveform only on an event

  can someone please help

  Thanks in advance...

  The value of the variable "Stop 2"is in memory still "True" so on that a second (and resulting) running that your upper loop always ends after the first run.

  The display of "stop 2' LED is to be reset when you press the button"Get the waveform". making the False value.

  So reset the variable button after finishing two loops or before starting the two while loops.

• Could not start the 2nd node - Exception ' this cluster node failed to deserialize the config java.io.StreamCorruptedException: invalid type: 100.

  I use a single node of consistency on Solaris 10, 64-bit 1.7 JVM. It works very well. However, the problems start when I'm trying to start a 2nd node of Eclipse running on the JVM 64-bit Windows that is configured exactly the same as on Solaris. Observing these two newspapers JVMs, I can see that each node detects the other, however, the node that was started the 2nd always gets the exception below and ends. It doesn't matter on what OS I starts it's always the 2nd JVM that gets this error.

  What can be wrong? What is my config? If it wasn't, why the first node set up and working properly?

  Here's the exception:

• How to set of Cluster nodes on the same network but on different gateways

  Hello
  We want to set of Cluster nodes on the same network but the connection through different gateways for Unicast (WKA). We strive to add sockets for < cluster-config > tangosol-coherence - override.xml file, pls help how to set.

  Looks like you are using the default configuration for the system property:

  8088
  true

  The probable reason for this question, it's the localport is unaffected as 8088 for communication on the machines. Either use the property system - Dtangosol.coherence.localport = 8088 and - Dtangosol.coherence.localport.adjust = false or see the node will connect and find node assigned to each node and open the nodes; recommended to use multiple addresses node as in unicast configuration below:

  well-known-address >
  
  
  

  XXX
  
  8088
  
  
  
  YYY
  
  8088
  
  

  See you soon,.

• Error: The property node (arg 1) in .vi VISA set up a Serial Port (Instr)

  Hello

  I've seen people once they have gotten this error, but none of them really apply to my situation.

  Right now I use LabVIEW example code to read from a device manufacturer. This device is connected using a Tripp Lite USB adapter series (http://www.tripplite.com/en/products/model.cfm?txtSeriesID=782&txtModelID=2430) for the connection from the PC to device with RS232. The adapter works fine when using the software prepared in advance (not LabVIEW) given by the manufacturer and the COM port is seen by LabVIEW. When I run the program, I get the property node (arg 1) visa set up a Serial Port (Instr) .vi (I've also attached the VI but it's a standard VI I got of LabVIEW). I get this error despite the fact that I use the same COM port, who has worked with the manufacturer's software.

  I have attached manual of Protocol RS232/debit BUS (not sure if this applies) that requires the device. The device is a mass flow controller whose operating instructions is: (http://nemu.web.psi.ch/doc/manuals/device_manuals/Bronkhorst/917023--Operation%20instructions%20digi...

  I'm using LabVIEW 10.0.1

  Any help is appreciated

  Try to restart the PC and then try the LV version before trying other software.

  I have seen thrid party serial interfaces work on the first try but fail when you switch to another application. It was as if the pilot did not know that it was no longer the first process.

• How to access the property of ListBox inside the Cluster element names?

  In LabVIEW 2010, I have a group of controls on the front panel. In this group, I have a ListBox. How can I access the Item property for the ListBox object names in my block diagram.

  Of the bunch, I can get control ListBox, but which returns a value of I32, probably the index of the selected item.

  In the block diagram, how can I get the name property of the item in the ListBox control since a reference to the Cluster?

  Thank you.

  using the table 'orders' in your cluster, you can access each item. Next, you will need to convert the reference to a 'class more specific' with a reference to an arbitrary list box (or a constant reference of the required type), then you can access all the properties of your listbox.

  

• Unable to modify the property in the property node

  Hello

  How to eliminate ghosting of my measurements? :

  However, when I try to use a property DAQmx Timing node, I am not able to change the property (see screenshot). I tried right click and left click and clicking on everywhere.

• Value property (signage) for the event - button press the joystick

  I tried to use my Logitech joystick button to trigger events.  I read several messages and LV help on how to register for events, and I have not found exactly what I need.

  I understand that events are generally not triggered by contributions of NON-INTERFACE, but I keep reading messages that make it sound possible.  Book LV Basics II says: "NOTE of Clusters are the only container objects for which you can generate events.  LabVIEW generates events control for clusters, before it generates events for the objects they contain, except in the case of the value change event.  They Value Change event generates the event part of the cluster, click the cluster itself. »

  So, the gamepad buttons and axes are in clusters and I'm trying to detect a change in value for items in a cluster (see the attached below .VI), but the event is not the trigger.  If I press the button 9 on the broomstick, the LED should light and channel indicator should say that the event has been triggered.  It is a simplification of what I'm trying to do, but I think that if I can do this simple case work, I can do the rest.

  It was created in LV10.

  So what I am doing wrong?

  Thank you, Ed

  Oh, I think that we have understood what you have when asked. We all said that you need ASK the joystick in a LOOP
