• How to get the updated values of the loops while they are running

  Hello

  I am trouble with a very basic problem, how to access the updated values of the "loop FOR" during operation?  Basically, the VI I is currently working on two sub vis calls each sub VI has a loop for, and the two screws may or may not work for the same number of iterations. My goal is to read the values in each terminal within the loop of two sub VIs, in primary VI. I tried to do this using Global Variables, but in main VI it will display only the last iteration of the two value sub live. Could someone please tell me whrere I go wrong? Is there any other/better way to do this.

  I appreciate any input on this issue.  

  Pass a reference of the main VI control to the Sub screws.  See attached example.

• How can I change the value of a control on front panel?

  On the front panel, I'm doing a complex control that consists of a Slider control and control of the digital inputs. Both controls display the same information and either may be used for entry. When changing value, I want the other control to display the same value.

  How can I change the value of a control on front flap when another control changes the value? I know how to use a structure of the event to detect value has changed, but I do not know how to impose control on front panel to change its value in the block diagram.

  Why do you not use a digital display on the slider, and no code is required:

• Reminders does not work in the executable LabVIEW front panel

  I have a couple of reminders in the process template that trigger an event in the event structure to update of the lights on the front panel for the user. Everything works fine until I have create an executable file. This can also be an indication of the other points, I have not discovered yet.

  Any ideas?

  Thanks for all the help.

  Found!

  Not unlike most of LabVIEW developers, I have a range of utility screws that I use over and over again. Such vi is vi uses a property node to find out what environment the application is running in, i.e. .llb, exe, development, publishing student, etc.. This vi is used because SEO screws in an executable file have a way different than when their listing in the development environment. Using this vi allows your code to reference the screws properly when developing and when the executable is built. The code still works because it automatically adjusts the referenced path of the vi. See attachment 'Path Finder.vi environment'.

  Now for the fun part! For some reason, perhaps because of the friendly character of NOR and the relationship it is with its developers :-), AND decided to change the path of the executables in LabVIEW 2009. After hours of troubleshooting and countless rebuilt, I came to the conclusion that the ' paths of the band of "work magically stopped working. It was at this time one of my friends happened to walk and ask why I had everything in my monitor across the room (figuratively speaking of course, I'm sure we've all been there). I explained what could be the only conclusion, band paths do not work!

  My friend immediately began laughing, having recently had the same problem. He explained that in LabVIEW 2009 executable paths are different and our 'find the path vi' would not work. He added that NOR, after finding this funny, however gave the developers a way to solve this problem with a check box within the app Builder. The box is called "Layout using LabVIEW 8.x file." See attached photo named "App Builder."

  The only thing I could say to my friend was, ' silly me, I should have know what that.»

  Laughing out loud

  Thank you for trying to help, it launched my butt.

• Screenshot or image of the camera in front panel

  Im trying to take a snapshot of a CCD image in my front panel every time my program iterates. CCD image is updated of my camera which is connected online. Ideally, I want just to save an image in .jpg of this image of the camera of each iteration, but I can't do with the invoke node option. Any ideas?

  Is attached a screenshot of the front part, let me know if you need the real VI

  Hi Manderson13,

  Norbert is absolutely right that you can record images using the NI Vision software. What kind of camera you have, and how you currently gain to display images on your front? Documentation on how that here you can use our vision software to record images to the file.

  Thank you!

• Change the values of the cluster in while loop and in the face at the same time

  Hello.

  I have a little problem in a test program, that I'm working on. I'll try to simplify as much as possible. I have a cluster control that contains two controls A and B. I want to:

  1. switch to update the value of the command A a while loop
  2. allow the user to change the value of the B control through the face, while the loop is running

  To change the value of order in the while loop, I first get the cluster control cluster, update the value of the control for a way to group by name and finally rewrite the cluster in the cluster control.

  The problem is that if the user changes the value of the B control while control that is in the middle of the update, the new value of B control is lost because it was read before updating in the face. Is there a way to get around this?

  DennisBengs wrote:

  1. switch to update the value of the command A a while loop

  Then they do not belong in the same cluster.  They are disconnected obviously enough that they do not go hand in hand.

  Where it can get really complicated, it is that you're talking about the user and code changing the same cluster.  It is very dangerous and very difficult to manage.  You might be able to get there with a driving force.  But walk slightly, my friend.

• The time on front panel display

  Problem solved.

  Apologies to remove the original message. He initial post was something like this:

  --------------

  I twice parallel loops running - 1 who acquires the data every 30 seconds and the other just infintely loop to show the time on the front panel. But for some reason, timed loop data acquisition has been working well and do not release control to the other timed loop - for this reason present on the front was not getting updates.

  --------------

  After various discussions, I found what was my mistake:

  There are dependencies between the 2 rings - and no doubt because of the time was not getting updated.

  Solution:

  http://forums.NI.com/NI/board/message?board.ID=170&message.ID=75933&query.ID=60956#M75933

  Instead of using 2 timed loop, I used a timed loop to purchase and a while loop as explained in the thread above to display the time on the front panel.

  I hope this helps.

  Thank you.

• How to get the updated value once the database is in place?

  Hello
  
  I have a scenario which is explained below.
  
  I have values from the DB for the first time and then consecutive application gets the value of the cache if the key is the same.
  One application is to apply. At that time, certain values change in the DB and then the DB is declining.
  
  Once the DB will get the new value of the cache. I tried this but I got the value from the cache (obtained only old value). The key is the same in DB, I changed the value and tested it.
  
  Is wot in the way that I am doing is correct? The same thing happens when I put the value in cache when DB is out of service.
  Will the data get updated as soon as the DB is in place? Also, this is not the case when I tested.
  
  I made the scenario above using distributed cache with manual configuration file that uses dumps.
  
  
  Thank you

  The cache of almost is a "cache cache", then it can expire items out of its cache of 'before' (the local cache on the JAVA virtual machine running the code that requests information from the cache close), but which does not expire items in the cache 'return', which is the distributed cache.

  Caches are assembled in a hierarchical way, your configuration is something like this:

  1. a "cache near" which consists of a "local cache" (expiration) front and a back "distributed cache.
  2. the "distributed cache" that has a "reading / writing support map" for its data storage
  3. the "reading / writing map support" that delegates to a "Cache" store to talk to a database and a "Cache internal" for its storage
  4. the "internal cache' is probably configured as a storage card by default (which has not expired)

  To make data expire so that he is re-read, simply change the definition of "internal cache" in the read/write backup plan to use a similar setup that you use on the front of the cache close.

  For example, the example configuration file "coherence-cache-config. XML"(found in coherence.jar), you can change this"1 h"to 10"s"and expiration will occur in 10 seconds instead of an hour:

  
  
    example-binary-backing-map
  
    HYBRID
    {back-size-limit 0}
    BINARY
    {back-expiry 1h}
    1m
  
    
  
  
  
  
    example-read-write
  
    
      
        example-binary-backing-map
      
    
  
    
  
    true
    0s

• How to add the hyperlink on front panel

  Hello

  I want to add hyperlinks on my front. After clicking on who can access run another VI of disc or simply give me the functionality of a booleon control.

  I don't want to use the button for this.

• Where is the documentation on front panel objects?

  This might be a stupid question, but is it helps on objects of façade? For example, on the front panel, I chose

  Modern-> list, table & tree-> Listbox.

  Now, I typed the letters A, B, C in the list box and right click on the node of the list box on the block diagram and witness of the. Of course, he showed the list again.

  I noticed that the wire was a blue line "BOLD". I wired then that a for loop with indexing turned on, and this time I ran inside the loop, I created a new indicator

  the VI and inside the for loop through the indicator, I saw a number, which was the index of the last item selected in the Listbox.

  Well, if you're wondering where I'm going with this, here's my question: How do we find out (where is the documentation) that tells a user of the blue line "BOLD" on a Listbox

  carries information on the entries in the list box, as well as the index of a selected item? I mean there are a lot of other façade objects that do have not any help documentation.

  What a person to learn on items in the front? On the block diagram, I can mouse over, press Ctrl-H and click on detailed, help but cannot do anything on the front panel objects.

  All Web sites that can help you with this?

• Double-click the object of front panel to find the terminal block diagram

  Hello world. I don't know why, if I double click on an object to front panel, labview opens the front tab customize, instead of finding control in block diagrams, which would be the normal behavior, as I read in http://labviewwiki.org/Tips_and_tricks#Debugging.

  I tried to reset the initial Setup by renaming the file LabVIEW.ini, but it doesn't seem to work.

  Do you know how double-click the object on the front panel and locate the?

  Thanks in advance!

  Guille.

  Did you restart LabVIEW after you rename the file labview.ini?

  There is an option (Tools... options...... general façade... 'Open the editor control with double click').

  It always seems to be set in your case.

• Need a solution to update values in the table

  My version of oracle is 11 and my table name is nit_xml in which column the name is cust_dtls
  
  Nit_xml table data
  
  
  < root >
  Nitesh < Cust_dtls > < / Cust_dtls >
  < / root >
  
  I want to just update Nitesh Nit...
  
  Its inserted i through this way, values
  
  INSERT INTO nit_xml
  VALUES)
  ' < root >
  Nitesh < Cust_dtls > < / Cust_dtls >
  < / root > '
  
  So I tried to update my way like like that
  
  
  
  UPDATE nit_xml
  SET cust_dtls = ' < root >
  Nitesh < Cust_dtls > < / Cust_dtls >
  < / root > '
  WHERE cust_dtls = ' < root >
  Nitesh < Cust_dtls > < / Cust_dtls >
  < / root > ';
  
  But not working if anyone can give me any ideas about XML as well as how it works and what is possible or not to update through query... His note I want to update the column cust_dtls based on the same value of the column and not any other data type number or varchar2 because that based on other datatype it works easily and the second thing her i use application TOAD while the manual update is possible which is very good, but I need to update directly through query...
  
  
  
  Kind regards

• Add data from serial Port in the indicator series front panel?

  Hello! Everyone,
  I'm new to LabVIEW but has prior programming experience.

  I have to develop a front for my camera and this is why I need LabVIEW, data comes from serial Port, so I started internet research / LabVIEW forums and found various tutorials by the help I am able to do the part Serial Communication, but has got stuck in one thing.

  Whenever data from serial Port, it gets displayed on the indicator chain but clears quickly, but I want some data comes it does not erase the old data and new data to add with the old data.

  I read the string concatenation will work in this case, but I am not able to use it.

  Please take a look at my VI attached to this mail.

  You must use a shift register to keep your story.

  

  I recommend you go to some of the tutorials available.  They will help you a lot to get off on a lot of things like that.
