• How to use the global variable in the table target?

  Hello

  I am trying to load several files into a single interface. the data is loaded successfully. 92. the files are there. for this I used variables and package.

  My requrement is 92 files of data loaded into the target table. I want to know what data from file.

  to this I added a column (filename) to the existing target table.

  If I used joints (not same condition), its totally wrong. all file names are coming.

  Please see the following screenshots.

  

  exit; target table.

  

  in fact in the target table. first 10 lines are coming from file.i.e first _ACCOUNT_LIMIT_511.TXT. but all the files names are coming.

  I'm confuse. After the first data file inserted then insert second data file. in that all file names are coming. Please help me.

  I thought that the global variable is preferable to identify the data came from which file.

  to do this, the global variable is used in the target table. I don't always have my exit.

  Please help me.

  Thanks in advance.

  

  Hello

  You can use the same way, how you use the project variable, just you have to do a thin is #GLOBAL.variable_name for example: #GLOBAL. SMART_AL_FILE_NAME_S

  Note: Make sure you that while you use one variable overall in interface, indicator should be staged as you chose above the screen

  hope this helps you

• Dynamic read the global variable (cluster)

  Hello!

  I would like to lika to read each control (label and value) in my global variable that contains a cluster. The problem is that I am doing it on a cDAQ and insofar as I undestand and has seen property th node do not have good worl on a real-time target. The code that I've tested so far is as follows:

  

  It's the main/fornpanel on my cDAQ. The Subvi in the main code contains the following:

  

  The phenonomen I've seen against hepatitis a is that it works very well maybe the first and second time when I run cod drank for the third time that the labels are empty. I read something that the dose of propertynode does not correctly for real-time target, but it is a way to come to the same solution using only not not the propertynode or you could use the different propertynode?

  Best regards

  Anton

  I solved it by using a library (Cluster Toolkit of Autotestware) to the GE in variant tables and depending on the type, I converted the variant accordingly and saved.  I guess that CVT would be able to do, but since I already use the cluster and they are "already here" it was more convinient for me to use this solution.

  use shared unique process variables. But I started now return to
  using the old global variable because I think that there are some significant drawbacks
  to the single shared variable. Here is the ability to search for
  case of variables and also the ability to view or change the value of
  the variable (OK, we have the variable Manager, but I found slow and)
  unstable). My question is, are there reasons to use the new single
  process variable actions on old global variables?

  Dear Terje,

  As you use only the variables on a single system. There is no advantage to the use of unique process shared on Globals variables.

  Infact a global variable uses a little less processing power that a global variable as the implementation of a shared variable single-pocess effect is a global variable with the timestamp feature.
  If you use a shared variable single process, if you don't need the timestamp feature, then disable it to use less processing power.

• Retrieve the label of a cluster in a global variable

  Hi guys!

  In my application I was using a bunch of Boolean values for the different types of errors that I could have in my Subvi.

  It was not really practical manage all of these clusters, so I decided to create a world.

  Now the problem is I can't extract the labels and values of this cluster. Before I spent as the thesis reference values, but I think there is no way to create a reference directly from my global variable (cluster).

  As you can see in this printscreen so I created a new table indicator in my VI. But if I add a new Boolean value into my global cluster, I need to create the cluster once again and it is not really practical.

  The goal is to list the errors in a string only if the value is true.

  I don't know if I'm clear, otherwise I can explain more.

  

  Hi remvu,

  have you tried to insert a "to a more specific class" before the node property-ctl?

  Because you always want to know the names of the Boolean, you really should give it a shot to typedefinitions...

• formula with the global variable node

  Hello

  I'm tring using node formula with global variables as an entry and exit.

  but this is where I see the SW hangs forever.

  Either way, I am a novice to the labview.

  Can some give me advice why this is happening?

  Thank you in advance,

  Do

  As smercurio mentioned, if you described what you wanted to do, we could show you things that can be done using LabVIEW.

  For example, loops For may not be not necessary if you are trying to extract or manipulate data in tables.

  It is good that you have a job, but it would be better to learn the power behind LabVIEW.  Who knows, you can actually walk away from C code...

• Impossible to go from baseline of connection via functional Global Variable

  Hello

  I'm working on a project of producer/consumer based, which some parties have access to a MySQL database. After the connection to the database, I want to store the reference to the connection inside of a functional global variable. Then other parts of the project that need to use it can only read in the functional global variable.

  For some reason, the reference of the connection is not valid once it has been read functional global variable. It works fine if I have the reference directly from the connection to the request for enforcement VI wiring.

  I have attached a few screws that show the problem, but you will not be able to run them unless you have a database to connect to and hack you the query a little so he selects in your tables.

  SQL_whole_thing works very well. It connects to the database, returns information he requested by the query, and then disconnects. No problem.

  But if I run DB_Connect.vi (which stores the reference to 'DatabaseID_FGV' FGV), follow-up of SQL_Query.vi (which reads to the FGV reference), then I get an error saying that the reference is not valid.

  Anyone has an idea why this happens?

  Thank you

  Christian.

  PS: You'll need DBID_FGVActions.ctl and database_connectioninfo.ctl, also attached

  Your referance on the SR's "outdated" when implementing this way.  Essentially, this means that data in memory to this referance has changed because the referance was stored.  Just because you have changed the data at this location.  This prevents you from spend a refeance for the "old data" and crashing the calling application since the referance Rassi contains assumptions that are more adequate data.

  Consider upgrading this FGV powered Action.  This would be encapulate all the Actions you want to do to the database (connect, disconnect, fecth, writing etc.) and maintain the current referance on the AEs shift register.  Ben establishes a great deal for just this type of functional encapsulation in his famous nugget.  A must read for every programmer

• Package global Variable - Collection - Associative Aray

  All,
  
  What we are doing is...
  (1) fill us tab_emp_sal_comm with big collect and browse in a loop.
  (2) check if the deptno success is available in the tab_emp_sal_comm collection.
  (3) if it is available to fill a collection called tab_emp_sal_comm_1 and push corresponding only files inside.
  (4) of the corresponding collection, we want to fill at the table of global collection of package which is again of the same type.
  (5) by default for each new call old values are replaced, but I want to add the global variable at each call and finally do a big update to the corresponding tables.
  (6) l_deptno will be a parameter and values will change at each call of this procedure in the code in real-time.
  
  For the sake of ease, given an example simulated the EMP table. Goal is to add the global table in the package. Because each call, the previously loaded values are replaced. I want them to be available and additional calls should only add the values in the next set of lines instead of over writing.
  
  How to achieve it, please discuss.

  Hi Ramarun,

  (1) operator MULTISET, AFAIK, is to always give a dense nested table. To create a sparse nested table, the only way is to delete some items with the DELETE method.

  (2) using the 1... NesTableVar.count is valid only when the collection is dense. With the release of MULTISET UNION you won't have a problem. But if you have a loop in a rare collection, you must use another method.
  Below is an example:

  declare
    type  t_set is table of number;
    set1  t_set := t_set(1,2,3,4,5,6,7,8,9,10);
    idx   integer; 
  
  begin
    -- make collection sparse
    set1.delete(3);
    set1.delete(7);
  
    idx := set1.first;
    while idx is not null
    loop
       dbms_output.put_line('Set('||idx||'): '||set1(idx));
       idx := set1.next(idx);
    end loop;
  end;
  / 
  
  Output:
  Set(1): 1
  Set(2): 2
  Set(4): 4
  Set(5): 5
  Set(6): 6
  Set(8): 8
  Set(9): 9
  Set(10): 10
  

  (3) you can use FORALL update/insert/Delete with the help of a nested table. It is dense, you can use 1... NesTableVar.count, if it is rare, then you must use another method as explained here.

  Kind regards.

• Loading a file into a global variable problem - really a global var text?

  Of all the documentation and the examples that I can find, it seems that it would be

  fix to create a global table [outside any function] variable to load image names

  then use these images to a slide show. I want to do the dynamic application, modify the text file as a new series of images.

  The global variable passes zero [any value] after the load event listener. Why is this?

  Is not global and world alive for the duration of the SWF?

  PARAMS. TXT:

  monthNames = January, February, March, April, may, June, July, August, September, October, November, December of & dayNames = Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday

  CODE:

  var dNames:Array = new Array();
  var mNames:Array = new Array();
  var request: URLRequest = new URLRequest("images/params.txt");
  variable var: URLLoader = new URLLoader();
  variables.dataFormat = pouvez;
  variables.addEventListener (Event.COMPLETE, completeHandler);
  Try
  {
  variables. Load (request);
  }
  catch (error: error)
  {
  trace ("unable to load URL:" + error);
  }
  trace ("2 mNames 2:" + mNames [2]);
  trace ("2 dNames 3:" + dNames [3]);
  Stop();

  function completeHandler(event:Event):void

  How to access these values after the loading of the external file, after charging?

  Thanks in advance.

  The statement you quoted all Adobe documentation is correct.

  If you want to load the data into the tables before anything else happens, then have everything that happens to run via the function completeHandler... when the data is loaded and processed in the tables.

  the command: loadFile() runs before the trace ("2:" + images [4]); command.  The loadFile function is processed and loading process BEGINS... but begins loading does not delay the main treatment to continue down the line - the loading itself becomes a secondary/background task.  The order was to run the function loadFile and the processing of this function has been completed.  If you don't believe, then add a trace...

  function loadFile (): void

  {

  vars.dataFormat = pouvez;

  vars.addEventListener (Event.COMPLETE, onComplete, false, 0, true);

  Vars.Load (new URLRequest("images/fnames.txt"));

  trace ("implementation");

  }

  If you add this trace, you will see the execution of function loadFile is completed and the following line in your code is then treatment... trace (2...)

  The addEventlistener method does not stop anything.  The addEventListener method code is assigned a monitor, not a traffic controller... it's say the monitor to indicate when the loading data are complete.  It does not do anything to stop the execution of the program.

  So if you want to wait until the data is loaded before anything else... it goes...

  function onComplete(evt:Event):void

  {

  var urlVars:URLVariables = evt.target.data;

  images = vars.data.images.split(",");

  tnails = vars.data.thumbnails.split(",");

• Using global variables in a device custom

  Hello world

  I have problems with the passing of data through my device customized using global variables. I want to allow a user to select a RIO device address when you set up the system definition file. This is recorded in a global variable using the hand Page VI. I would later use this RIO device address in RT driver to deploy a bitfile. I can hard-code, but it is much more convenient to use a global.

  When I try to store the address of the global variable, it updates the value temporarily (I confirmed that the structure of the event recognizes the change of value). When I click the node of the tree to define system linked to the Main Page VI and then click on it again, the hand Page VI runs again. I wrote the code to repopulate the address of device of RIO with the last value stored in the global variable, but it is empty. I've included the VI global variables in my build, so I can't imagine why it can reset this value.

  Any help would be appreciated!

  Thank you

  Mitch

  Have you tried to use the custom device properties to store this value instead of GVs?

  Configuration VI, you can set this property, and if I'm not mistaken, you can read these properties on the RT driver.

• DLL and global variables

  OK, here's a strange problem.  I am very new to create the dll, so I don't know that I have just an installation problem.

  But I'm trying to pass a global variable of a host program to its attached DLL.  I got this job when I was the CVI 2014. I recently upgraded to 2015 and then started getting "undefined symbols" errors.  With some struggle I managed to compile again, but broke the variable connection in the process.

  I have compiled my DLL in debug mode so that I walk in from the test project.  Right now, my global variable exists in the test project, as well as in the DLL.

  Can I export the variable and the use of DLLIMPORT/DLLEXPORT?  Confused and curiously not to find anyone quite like this on the forums.

  EDIT: this post stack overflow described pretty well from my experience.  I am linking statically.

  Well, what do you know?  I found my problem.  This draft article and example WERE vital to the solution.  This article called, "using the Export method qualifier"was also useful.  I'll cut to the Chase...

  If you use a qualifier of export on the definition and the import on the declaration, LabWindows/CVI identifier export symbol.

  This is the right key.

  So in my example, it should look like this:

  DLL fichier.c

  int DLLEXPORT varName = 0;

  Header.h DLL

  int DLLIMPORT varName;

  Project that uses DLL.c

  #include "header.h DLL.
  
  varName! = 1 ;  a method to change this variable for local use

  Pretty easy, huh?  But wow, it took some time to find.

• How to extract file with LabVIEW Teststand global variables

  Hello

  My goal here is to extract all the contents of the global variables for file (names and the value of any types) in a sequence of my LabVIEW UI file.

  For now, I can only open a file of sequence of LabVIEW and get the number and the names of the variables (cf. vi) attached.

  But if my variable is a container, I would like to know all the contents of this container (and so on) and I don't know how to do it.

  In addition, I have to extract the value of variables that I don't know the type in advance...

  Can you help me?

  Thank you.

  Well I finally used the method "GetNthSubProperty" to work on each variable and I use the property 'Type' to know if it's a number, string, boolean, or a container. If it is a container, I repeat the process at a lower level... (see attached vi)

• Global variables for circular buffer

  Hallo!

  I have another question:

  Is this possible? I tried to use the global variable like {VAR_01} to insert in the field that you want to the memory size circular buffer, but dasylab puts only a zero in the field.

  Thank you and have a nice day.

  Unfortunately, it is not possible to have a variable size buffer. Right-click in the textfield corresponding: the shortcut menu does not show an entry to select the global variable from a list.
