• How to save the text file input array

  Hello, I am very new to LabVIEW, so apologies if I use the wrong terminology.

  I did a VI which reads 25 text files from a 3D array.  When I click on run I need to select the files 25 text.  Is there a way I can save the data imported for later calculations without having to select the files each time?

  Here's what I have:

  Thanks for that.  But the user will not have access to these files during execution of the VI.  There are many other paintings that I'll need to save and index for other variables as well, so just for that would use the method of you would be useful to know.  All I really need is a way to save these relatively few values in a table.

  So do you intend to have these values hard-coded into your executable?  This seems dangerous and likely to have you to make updates much.  Believe me when I say you want to have the sitting files with the executable.

  But if you're insistent on this, I would use a global variable.  Have a VI just read all files and build the table for you and write in the global variable.  Then you can right-click on the control on the Panel before global variable 'Create default value'.  Save the variable and build your executable file.

• Problems to get the Variables of functions

  If possible, could someone explain to me how function to produce variables.  Here's what I'm trying to do.  I have a CSV file that I'm importing.  I would then like to run function for each row in the CSV file and produce able to use in the script.

  For example,.

  I have a function that looks to see which version of windows operating system and will assign a key to license based on this variable.

  Function Determine_Win_License_Key {}

  #$erroractionpreference = "SilentlyContinue".

  $CSV_Guest_OS = $_. Guest_OS

  Switch ($CSV_Guest_OS)

  {

  2003 x 32 {$GuestOSLicense = "License key 1"; break}

  2003 x 64 {$GuestOSLicense = "License key 2"; break}

  2008 x 64 {$GuestOSLicense = "License key 3"; break}

  2008r2x64 {$GuestOSLicense = "License key 4"; break}

  }

  }

  Based on this function, I set the $GuestOSLicense variable to be used later.

  The body of the script looks like this:

  Import-Csv csv.csv | %{

  Write-host "license key of determination."

  Determine_Win_License_Key

  Write-host "the used license key is: ' $GuestOSLicense

  }

  I expect to see what is the license key but all I get output is

  "" The used license key is: ".

  Someone know or understand why the function runs but does not save the variable generated by the function?

  I have several other functions in this script, and each of them do not return the variable.

  It's because you return anything in the service.

  One way to achieve this is

  Function Determine_Win_License_Key {
     param($OS)
     #$erroractionpreference = "SilentlyContinue"
     switch ($OS)
     {
        2003x32 {$GuestOSLicense = "License Key 1"; break}
        2003x64 {$GuestOSLicense = "License Key 2"; break}
        2008x64 {$GuestOSLicense = "License Key 3"; break}
        2008r2x64 {$GuestOSLicense = "License Key 4"; break}
     }
     $GuestOSLicense
  }
  
  Import-Csv csv.csv | %{
     Write-host "Determining License Key"
     Determine_Win_License_Key -OS $_.Guest_OS
     Write-host "The License Key being used is:" $GuestOSLicense
  }
  

  It is also best to pass a parameter to a function, rather than depend on variables in the function, which are initialized defined outside the function.

• Save the value of a Boolean variable

  How can I save the value of a Boolean variable, so that when I open the file, it can be with the parameters in which I left?

  I created the variable to the top of the frame:

  var audio:Boolean = true;
  

  And I added the conditions for the buttons:

  if(audio == true) {
      Sound.play();
    }
  

  But whenever I open the application preferences is reset to true, wanted to leave with this preference be saved in the case of boolean, true (enabled) or false (disabled).

  can someone help me? Please, I beg you.

  Thanks in advance!

  A sharedObject is always appropriate for a local application. The only reason to use anything else would be size of storage needs.

• Set/save the value of the local population of LabView development

  Is it possible to set/save value of the inhabitants of Teststand of LabView in the update, so I do not write the value in the variable pane? I can do this to programmatically at runtime with SetProperty, but I want to define them in the update with a VI.

  Thank you

  I use LabViwe 2012 SP1 32 bit and Teststand 2012 SP1

  You have to access the SequenceFile inhabitants and then save it to disk.  I have attached a picture and my code.

  Kind regards

• What happens to the values of the variables cRIO restarts?

  Hello!

  I am currently developing a software that runs on a cRIO as a start-up program. I encode a production counter to determine how many products passed the tests. A web server will be used sometimes check this counter...

  What happens to the value of the counter if cRIO power supply is turned off? The counter will reset to 0 when you restart? If so, how to avoid this behavior and restart with the last count?

  Hello

  Of course, what happens to your variables and what is happening in your program depends on... your program.

  If you do nothing your variables, they will have their value by default when the program starts.

  A way to change this behavior is for example save the value of variables in a text file and read these values at the beginning of the program.

  Hope this helps,

• value of the variable 'keep '.

  Hello world!!

  An applescript noob here!

  I'm trying to create a script using Automator to "find and replace" name of my client always in the same file in Textedit, so I can use this text by only to replace every time the name of the customer. (as a model)

  So far, I got this:

  display dialog "which is the name of your client?" default answer «»

  Set cst_name to text returned of the result

  dialogue box "are you sure you want to change it?

  Global customer

  the value customer cst_name

  Tell application "TextEdit".

  -Find and replace

  the value of each word in the document before where it = 'CSTX' to the customer

  tell the end

  My problem here is, of course, when the text 'CSTX' changed once using the scrip he is not called CSTX more, but the name I just enter in the dialog box guests.

  Is there a way to 'keep' the value of this variable so I can run this script as often I do.

  Do you guys think that this is an easier solution for this?

  THX in advance!

  If the first instance of it will always be in the same place of the document each time, you can get it with:

  Tell application "TextEdit".

  Words from 5 to 5 of 1

  tell the end

• How to control the value of a variable that is shared at the beginning of the vi

  Hi all

  In short: How can I make sure the values of the variables shared at the start of a vi?

  I have two vi.

  One is a main vi where did I order a shared Boolean variable "run DAQ".

  The other is a vi with a while loop that "polls" for the shared variable "Execute DAQ", which is connected to a box Structure. If the case is false, it does nothing, if it is true is short some simple IO DAQ within a while loop.

  To be sure that at the beginning of the vi the variable 'Execute DAQ' shared value false (no matter what 'State' the shared variable was left in front of the vi began) I write a Boolean constant to this shared variable 'Execute DAQ' out of hand while loop.

  Now my question: how is it possible that the case structure can enter into the 'True' State, even when main vi is not executed and there is therefore no way of the shared variable can be written in. I know that shared variables are stored in memory, but that's why I write it to false at the beginning of the vi.

  Even when I read the first shared variable before you change it with a constant False the second instance of the shared variable that is wired to the case structure bed to True.
  It seems to me that the shared variables do not follow the 'right' of the dependence of LabView and are updated outside the normal flow of the vi.

  Thanks for your time and advise on this.

  Someone knows another way around this?

  Yes.  Do not use them.

  If you not post on a network, use a normal Global Variable or use a queue, the user event, stating to send commands indicating loops for updating their values.

  If on a network, then I recommend the network stream to send commands/data back with updates.  I used shared variables, more I hate them.

• Monitor changes in the value of a variable in a module of code labview TestStand?

  Hi all

  A code in Labview module called from an action step has a particular variable that changes its value when running vi. Is it possible to monitor these changes through for example a local variable in TestStand and display different values on UI in real time via UIMessages?

  Thank you very much!

  You must post a UIMessage during execution of your VI.  As the following picture below, you can ignore the SequenceErrorMessage string and use the value of your variable as the numericDataParam.   I guess the trick is to determine where to display the user interface of Message, in your case, the variable updated at certain times or it he constantly updated?  I'm not sure of the performance LAG if at all times you post a UIMessage say every 100ms.

  

  On the other end, you will need in your interface user create a reminder of the Interface to manage the UIMessage.  See the following link for more details.

• I press graph sliders to save the values of the form, why?

  I want to save different values in a chart in excel.

  My program takes a signal and then I can adjust the interval I want to watch, and then change that with two cursors.

  I have succede with, the problem is that when I'm trying to save it, I have to first press save, then press one of the sliders to get the pop up window so that I can choose the right location to save.  Continue to record different values, I have to repeat the procedure.

  I would like to just run my program and then adjust my cursor on the interval that I love, and then press save to store the values in an excel document and then continue to select different valuse and press save button to store multiple values and so on.

  Is there something in my code that I have to press the front sliders can save values?

  Best regards Maurlind

  I modified your code to show you what I meant

• TestStand 2012 keeps the value of the variable

  I have a problem with TestStand 2012 that preserves the value of the variable. I have a step and its parameters in the string variable. I use the expression step as Step.Settings += "00". I run the sequence under sequential model and the problem is that Step.Settings is equal to "00" on the first run, '0000' on the second throw, '000000' on the third race and so forth, but it must rest '00' on each race. I can't find the root cause. Anyone has the same problem and can advice how to solve?

  Try to uncheck the properties of the sequence > optimize reentrant calls to this sequence to the sequence that contains the step.

• Can I change the values of the variables in the variables view control?

  I want to use the variables view control in Labview. I see only the values, but I can't change the values or create new Variables. Will there be a chance to do?
  I use Labview 8.6.1 and Teststand 4.1.1.

  You must activate the edit mode for the ApplicationMgr, by setting ApplicationMgr.IsEditor to true. Note that you must have at least the license of the custom editor for teststand so that it works (otherwise it will prompt the user to activate a license with these privileges).

  Hope this helps,

• How to set the value of a variable in a cluster in LabVIEW to c#?

  Hi guys, I'm working on a small c# program, which by using the interface provided by LabVIEW.  And I know that, with the help of lv. SetControlValue (name, value) can set a variable just on the front panel. But in my case, there are several groups on the front panel. Then it confused me how to set the variables in these groups. For example, there is a cluster named clusterA and a variable named a., I tried something like this:

  lv.SetControlValue("clusterA.valueA",1);
  

  but it totally inoperable. Everyone has some experience with this sort of thing? Thank you very much!!

  Hey guys, thanks a lot for all your response. I just found a simple way to solve this problem. For example, there is a cluster named "ClusterA", and there are only two witnesses, who are: an int value named "IntA" (default = 10 IntA value) and a string value named "StringA" (by default the StringA = 'abc'). In c#, if you call the method:

  var clusterA is vi (Array). GetControlValue ("ClusterA");

  you will get a table looks like: clusterA = {10, 'abc'}; So if you want to change IntA 123, you simply do:

  clusterA.SetValue (123, 0); 123 the value, 0 is the index of IntA in clusterA, after this clusterA table = {123, 'abc'}

  After that, simply to make the table in LabVIEW using:

  VI. SetControlValue ("ClusterA", clusterA);

  and now you see the LabVIEW, IntA is changed.
