• Read/write in a variable using its refnum

  Hello

  I and VI and a Subvi. In VI, I have a Boolean variable a reference to this Boolean variable. The Subvi have entrance to this reference (see examples). Now, that's my question, in the Subvi can read and write the Boolean value of the variable in the VI. Can I do? How?

  Thank you.

  Hi kiftren,

  Just as you used the reference on the node 'Register for events', you can wire the reference to a node property/invoke (you can find these on the paddle 'Application Control'). Select the value property. With your current settings, the "value" property will return a Variant. This is because the "mechanical action" setting on your boolean in primary VI. Change the mechanical action to "Switch when released. The 'value' property now accepts returns/true and false.

• static reference with the global variable

  Hi, I used a static reference to a Subvi where I change a global variable before (3-4 years ago) and do not remember how I did it.

  It was something like these attachments, but now I'm using LabView 2013 instead of LV 8.6.

  The change in the overall operating system sees only not in the main vi (looks like the invoke node run vi does not work with globals).

  In addition the vi close with the invoke node close vi but not if I put the custom in the Subvi properties to automatically close.

  dkfire wrote:

  Why not call the sub vi as usual, just with the setting to display the front panel, when it is called?

  Use the connector pane to transfer the value of the sub vi Ok button when done.

  That's what I recommend.  If this is not possible for some reason, then you will need to use a flat Structure of the sequence to force the reading of the global variable after the Subvi is complete.

• Global variable in the progress bar

  I have an existing labview code that consists of a main vi, which is the GUI user, and several (about 70) under vi. I am trying to add a progress bar on the screen before (user GUI) which will be immediately after it hits certain sections of code. I write this using a global variable to store the value of the status and any attempt in the main on-screen progress bar after each increment. Is there a way to link the main progress bar value to the global variable so that it updates as soon as the value is incremented? The problem that I am facing is that when I update the global variable in a Subvi, the progress bar takes the value of the Sub - VI is finished, all the numbers to jump between the two. I know it's because I do not correctly write to the progress bar, but I don't know how to do. If this isn't a good method, are there any suggestions?

  For example:

  SubVi2 SubVi1 Vi main

  (1-4)                (5-8)             (8-12)

  Progress bar: 1 2 3 4 8 12

  (I tried the Progress Bar Library OR offer, but I need a progress bar on the front panel, not a sound upward, so I can debug for code execution)

  Thank you - Adam

  I would go with a motor of Action update the progress bar VIA referance Server vi.  Here is an example of the use of a side effect I have to make this kind of progress bar.

  If you have not read Ben nugget of action engine, it should be mandatory, you can find here

  By building a "resource module" (a special AE that keeps a referance to the resource to act on) after initializint EI, you can call any 'method' on the resorce from anywhere in the instance of the application.  These babys really allow you to do interesting things to the GUI from around where the real action takes place.

• Global variables are accessible from the local computer

  While he was trying to use RT project, I can deploy the file to the RT target and communicate with the host using a shared variable.

  But the host VI file returns an error stating that the shared in the pattern-block VI host variable is illegal.

  (RT.lvib\Link reqd\ 'shared variable' node is illegal)

  It also gives a description mentioning that global variables are accessible only to local machines.

  What is the cure?

  Hi Shan21,

  I think your problem with communication between the aim of RT and the host PC might be caused by how your deployment of your variables. Please take a look at the following and let me know what you think,

  Kind regards

  ******************************************************************************************************************************************

  When you make the executable of a project using shared variables, you must have a local copy of the variables on the deployment computer that are then linked to the 'real' shared variables stored on the target - cRIO, in this case.

  This means that the display of your project should look like this:

  

  Note: Two libraries, which can have variables with the same name because they aren't both on the local computer.

  The steps required are:

  1. create variables shared in the normal Manor on the cRIO:

  

  a. right click on the target
  b. new > Variable
  c. properties of the variables enter the name (stop); Data type (Boolean) and the Variable type (always in network-published).

  2. create variables shared on the host PC:
  a. follow the steps 1 a - c
  b. right click on the box to enable anti-aliasing

  

  c. linking to the URL of the PSP, click on Browse - and select variable on the target:

  

  d. click Ok.

  Note: Remember also to deploy the shared manually variable llb. See the related links for more information.

  It's from a base of knowledge to write soon.

• Storage of Variable year - 1 presentation

  Hi gurus,
  
  I have a requirement where I'm passing prompt value the financial year of the dashboard a narrative as mode @{YEAR}. I would also like to add to this narrative point of view @{YEAR} - 1 though when the user selects 2012 in line with dashboard, my narrative view shud go something like this:
  
  These data are for fiscal year 2012 and its prior year 2011. If the user selects 2011, then "data are for fiscal year 2011 and the year before 2010."
  
  How do I achieve using PV? Tried @{YEAR} - 1, cast to int - 1, etc.
  
  Please suggest.
  
  Thank you
  Dan

  You can refer selected variable value of presentation in narrative mode, but you cannot reach

  @{YEAR} - 1

  Try to use the expression @{YEAR} - 1 as one of your columns in the criteria, then hide and refer in narrative mode.
  That would help subtract you - 1 other wise, you may need to do the same using Javascript in narrative mode.

  Hope this helps, let us know updates

  Thank you

• Select clear a choice on re launch popup

  I have a popup with text of entry and select a choice of components with popup delivery mode lazyUncached.
  I run binding programmatically via popup when clicking on a command menu item.
  When the user started popup for the second time, he sees the entry that is provided on the first time.
  How can soc popup can be cleared for the second time.
  I am able to clear entry texts using resetValue over the link, but it does not work on SOC.
  11 1 1 5 jdev

  That's your problem. You store the selected value in the list itself. If you do this you cannot cancel it. You must store the value by using a different attribute. You can for example create a variable in your pagedef and store the value selected in there. Then you can remove this variable and it should work.

  To add a variable in the executable section of the links page.
  (1) open the page links
  (2) right click on the variables in the executables section and choose "Insert inside Variables"-> "variable."
  (3) in the dialog box to set a name for example typeSelected with type java.lang.Integer
  4) click on the green '+' in the links section, select AattributeValues, click OK
  (5) select 'variables' as a source of data and 'typeSelected' as an attribute
  This will create a variable of integer type in the page links. This can be used to store the value of the component of the soc. For this select the soc on your page and in the property inspector, add
  #{bindings.typeSelected1.inputValue}
  the property value. It will transfer the selected value of the CPS to the variable you created (remember autosubmit true for the soc).

  To reset the soc preparing him #{bindings.typeSelected1.inputValue} to null.

• 1 block from Intailization to handle multiline Variables does

  Hello
  
  I have a senario where we must pass multiple values for the particular user. so I created the session variable and there I went from the Variable.
  for example user: ABC, unit: 1, 2, 3 access.
  
  where in the block of intailization I m using.
  Select 'Variable', unit
  table
  where user = 'ABC '.
  and here 'Variable' is defined as a variable.
  
  
  Now we want to improve the senario where we must pass several segments in the same way.
  for example user: ABC, unit: 1, 2 3, Fund: X, Y, Z access.
  so can I use same block of intailization,
  Select the unit, 'Variable_fund', 'Variable', funds
  table
  where user = 'ABC '.
  Here, 'Variable' seize unit and "Variable_Fund" will capture the values of funds.
  or do I have to create the new block of intailization for the new segment?
  
  Thanks in advance...

  are the Sun unit and darkens the funds raised by a single fact table?

  and on which table do you put below the conditon... or dim?

  Kernel ". Dim - g/l account "." Code for the unit"= VALUEOF (NQ_SESSION. ("' THE VARIABLE ') OR VALUEOF (NQ_SESSION. ("' The VARIABLE ') = 0 OR
  Kernel ". Dim - g/l account "." The Fund Code"= VALUEOF (NQ_SESSION. (' "VARIABLE_FUND") OR VALUEOF (NQ_SESSION. (' "VARIABLE_FUND") = 0

  Just try to put the above code in the filter business under the user/group permissions model and it should work...

  If it is then turned

  Kernel ". Dim - g/l account "." Code for the unit"= (VALUEOF (NQ_SESSION. ("' THE VARIABLE ') OR VALUEOF (NQ_SESSION. (("" The VARIABLE ') = 0) and
  (Kernel". Dim - g/l account "." The Fund Code"= VALUEOF (NQ_SESSION. (' "VARIABLE_FUND") OR VALUEOF (NQ_SESSION. (("" VARIABLE_FUND ") = 0)

  See if it helps...

  Also can you explain what groups are and what you want to implement security...

• Qualification - adapter variable mapping

  Hello Experts,
  
  I have to spend the 'resource settings' as arguments to the task of the adapter (custom). I've done things below,
  
  Adapter task-> adapter-> selected variable a variable->
  
  Data type: String
  MapTo: resource
  Qualifier: Process Instance (displays only this option)
  Capital type: Server XYZ
  Ownership of assets COMPUTER: Server Admin
  
  But it gives an error during start-up. I know that I wouldn't give "Instance of Process" as a qualifier, but it does not list anything else. (In the task of user iPlanet qualifier lists two values 'Instance of server and process'). Why he isn't lsited in my case? Am I missing something?
  
  Please help me.
  
  
  Thanks and greetings

  Have you defined "IT resource Type Lookup Field" in the form of process that is part of your custom connector?
  I think that this is the reason why resource does not appear in the list of qualifications.

• For loops with the array variable

  I am using a loop for example with the name of the table in the select variable, but get a compilation error

  Help, please!

  Excellent. Oracle APEX (Application Express) is a web IDE and RTS - it makes heavy use of DBMS_SQL to execute SQLs and restore these dynamically in the form of Web-based reports, or turn it into XML for graphical rendering using Flash software.

  DBMS_SQL is perhaps more complex (and only really necessary when it comes true dynamic SQL at all stages - including the result of SQL), but we must know how to use and apply. It is a valuable tool at times.

• Get the error during the creation of the type of the Schema element variable

  Hello world
  
  To create a variable of type of schema, I do the following steps...
  
  Select 'Variables' after right-clicking on the bpel process. IN this window, go to 'Create VAriable' then select 'Element' type. Now in Type choose, I expanded the my imported schema files. And selected a type of item, and then click ok to create this variable. I get the message...
  TO SAVE ANY WSDL/SCHEMA FILES, YOU MUST HAVE A PARTNER LINK LOCATED IN THE DIRECTORY OF THE CURRENT PROJECT.
  
  Which is to say by whom.
  I imported the schema files in the project. After that I imported in the WSDL file also. Now why I am getting error during the creation of the variable. However, I can create variable directly in. BPEL file, then everything is fine. And it works too. But what is average with the error above? Why I am not able to create the variable via GUI?
  
  Thank you.

  Hello

  I have this same problem this morning, and I was going crazy, until I found this Web page on the internet:

  [http://technology.amis.nl/blog/1803/problem-importing-xml-schema-in-bpel-process | http://technology.amis.nl/blog/1803/problem-importing-xml-schema-in-bpel-process]

  The idea is that the jdeveloper is not very good with directories with spaces to work on the directory name. If you move all your work in a directory without spaces, it will work smoothly. At least, it worked for me.

• high utilization of the processor at the time to quit smoking

  I have an app that is complicated; the main VI creates VI_a and then VI_a creates VI_b.  I use the function of reference VI open as well as the method run a VI in a node to invoke to spawn the EIS.  VI_b adds and destroying x number of shared variables.  See subVIs.

  When it's time to quit the application, the main VI sends orders via global variables and queues to VI_a, which then sends commands through the queues, global variables and functional global variables to the VI_b.

  Just as VI_b closes, it defines a functional global variable to notify VI_a is to stop smoking.  Finally, he sets his FP. Property to FALSE.  This close emotionally to the VI.

  Once VI_a knows that vi_b has left, he finished his process of quitting smoking.  The next to the last step is to set a global variable to prevent the main VI is to stop smoking.  Finally, he sets his FP. Property to FALSE.  This close emotionally to the VI.

  Once the main VI knows that vi_a has left, he finished his process of quitting smoking.  The last step is to define its FP. Property to FALSE.  This close emotionally to the VI.

  Now the problem.  LabVIEW is still ongoing with at least 50% of the CPU.  In the Project Explorer, the cursor is an hourglass.  When LabVIEW stops hogging the CPU, the cursor returns to the selection arrow.  When LabVIEW frees the CPU usage, it does so very quickly.

  How can I the diagnosis made LabVIEW when all panels before screws are closed and should not be executed?  I tried to use the profile tool, but were not able to capture anything.  I noticed that most shared active smoking time variables, plus it takes LabVIEW to release the CPU.  I'm using LabVIEW 2011.

  Hi, Faustina,.

  It is enough to use in the public Service. Close the function to remove these SubVIs in memory; You must also use the narrow reference function. You can use the reference close before or after that you open your Sub screws; this document explains some details of this process. In addition, it would be better to actually stop all processes that are produce in your sub screws, to make sure that you leave no references open when you close them. Functional global variables do not leave memory until the VI that calls initially lets remember also, so it would make sense that the global variables you have loaded, more memory your application consumes. You use VI Profiler (Tools > profile > performance and memory) to monitor your screws?

  Best,

• FPGA "mean, Variance & Standard Dev ' VI

  Hello world

  I use the express VI 'average, Variance & Standard deviation' through the vessels: 130 samples of a given signal.  When I run the program, the Boolean value "True output" is always false.  Does that mean exactly?  The output looks like valid... This VI documentation is pretty poor.  Someone can explain what that output tells me?

  Thank you!

  -Alec

  

  Hi Alec,.

  OK, I now see the source of confusion. This VI does not support running averages - that's what we've been referring to as "image-based", producing a single measurement for every 130 incoming samples result and a single pulse of the valid data for every 130 samples of output. This mode of operation is similar to the screws based on the Bay (Mean.vi, etc.) in mathematics > range of probabilities and statistics, that take a table and a scalar output. The only difference is on the FPGA, we need to disseminate, in the table, a point at a time. That ye (a reasonable expectation) is analogous to the PtbyPt.vi means that takes a scalar input and updates the average result on every call. We have implemented the version based on the first frames because it avoids the need to store all of the table. To see exactly what we do on any of these screws, just right click on the node and select "Convert to the Subvi", where you can consult and/or modify the code to suit your needs.

  For an example showing a similar operating mode, you can view the example analog period measure (measure Control\Period and examples\R Series\FPGA Fundamentals\Analysis). This example shows an external logic added to lock the result for each period measure - that you have already seen, it is not necessary for average, Variance & gap since this locking is done in-house.

  If the documentation clearly explains the behavior above, which should meet your needs or is there anything else you would expect to cover?

  I'll submit requests for corrective action on the absence of an example and documentation for clarification.

  Thanks for the comments!
