Write multicolumn listbox value from subvi whitout reference

Hi:
 Is it anyway to write data to multicolumn list box from subVI without pass in reference? Because if pass in reference I have to pass a lot.
Like I can use Open VI Reference together with "Set Control Value" to set a String indicator text.  But I can't find the way to use open vi reference to set the multicolumn listbox text, I only can highlist which row.
Thank.

One thing you could do:
Write the multicolumn listbox reference to an indicator in your main VI. In the SubVI read that indicator value and unflatten it into a multicolumn listbox reference. Then you'll have the reference available in the SubVI as if you had passed it.

  • Multicolumn listbox value not updating

    we are vi in which we need to update values to listbox, from subvi to main vi, there are several buttons in our subvi and for every subvi there is further one low level vi which appears as popup window, what shold happen is when i calling the lowest level subvi, it has some controls and indicators, those values should get updated to the subvi for every low level vi i have to add value to listbox instead of replacing, it is updating correctly if some element is already there in listbox but if we are clearing that listbox after than trying to add value to it, it is not updating the value. There are 2 columns in listbox , to the first column we want to add the serial number for each device and to the second column we want ti add item description, but the only problem we are facing if listbox is empty it is not updating the value.
    below i am attaching the program, this problem is coming in instrument vi( which is subvi to top level vi,) and all other low level vi( every control on instrument vi is low level vi)

  • Getting the value from a StationGlobal reference variable in TestExec User Interface Editor Mode.

    Hi,
    I am using the TestExec User Interface editor mode, in the SequenceFileLoad callback from my sequence an instance is made from a C# code module
    (the code module is located in another dll) , this reference is stored into a station global variable.
    Now I want to retrieve the reference from the station global variable in my TestExec User Interface code.
    So, is it possible to get this reference back from the station global variable?
    Best regards

    Reading the StationGlobal is not a problem. But the problem maybe that your reference contained in your StationGlobal is probably not valid once the SequenceFileLoad has completed its execution which it will have done once the SequenceFile has loaded.
    Any references you wish to pickup are best down via one of the ProcessModel callbacks such as ProcessSetup.

  • How to write to Excel values from following measurements to neighbour cells?

    Hi,
    I build app for some measurements, "end" of this app:
    As you see I have few arrays (with 12 rows). I want to eksport 2 arrays to Excel. In upper case results looks like this:
    And everything is OK, this I want, but... When I run app next time I want to save this next results in columns C and D in the same file. Next app run - columns E and F, etc. How can I do this?
    Regarsds

    Express VIs (such as Write to Measurement Files) are basically "shortcuts" designed to provide a quick fix, but rarely allow much flexibility, such as allowing you to determine where to put your data on subsequent writes.
    What you are trying to do can be done with the Report Generation Toolkit, which includes components that directly link to Excel (I'm not sure if Write to Measurement File actually uses Excel or simply writes data in an Excel-compatible format).
    However, there's a minor complication.  The task you have stated is to write columns, with subsequent columns going to the right of existing columns.  There's a function in the Excel-specific sub-Palette to find the last row, which you can use to write rows, with subsequent rows going below the last row.  It's not too difficult to use the functions in the Report Generation Toolkit to basically do what you want, but it isn't exactly straight-forward.  It would be a lot easier if you could write your data in rows ...

  • How to get a value from applet in jsp?

    Dear all,
    I have a jsp page which includes a applet (in a form). User click to my applet and get the value.
    and the jsp form can capture the value of the applet and send to servlet.
    Is it possible?
    If it is possible, how to do that?
    Thanks.

    Hi,
    Yes it is possible. You have to use LiveConnect.
    The classes required are netscape.javascript.*
    They are located in the jaws.jar file (jre/lib).
    Here is a copy of the page found at http://www.rgagnon.com/javadetails/java-0177.html
    Read/Write HTML field values from JAVA
    [Netscape AND IE4 compatible]
    The netscape.javascript.* (LiveConnect) package provides facilities to directly manipulate HTML FORM components.
    JSObject win = (JSObject)JSObject.getWindow(this);
    JSObject HTMLInputText = (JSObject) win.eval("document.forms[0].elements[0]");
    String testValue = (String)HTMLInputText.getMember("value");  // read form value
    HTMLInputText.setMember("value" , testValue + "new stuff");  // write form valueBut this action requires a signed applet. in Netscape, you must PrivilegeManager.enablePrivilege("UniversalBrowserRead");
    PrivilegeManager.enablePrivilege("UniversalBrowserWrite");
    before using an JSObject related to an HTML document.
    But there is a workaround, simply pass the informations through Javascript functions!
    [JSjava.java]
    import java.applet.*;
    import java.awt.event.*;

  • Add text to specified index in multicolumn listbox

    Hi!
    I have smal problem with multicolumn listbox. My application should
    create list of values where user can increase and decrease values of 1
    or more tester at same time.
    e.g when user gives for tester 1 values 1 - 5, my vi creates list where values are displayd like this:
    1
    2
    3
    4
    5
    after that user gives for tester 2 values 5-1 and my vi creates list where values are displayd like this:
    1
    5
    2
    4
    3
    3
    4
    2
    5
    1
    etc.
    First I planned use insert into array function where for 1:st tester
    row index would be 0,1,2,... and for 2:nd tester row index would be
    1,3,5,... etc. One problem in this solution is that if tester 2 have
    more values than tester 1, there will be left empty rows between
    values. I planned use string replace to solve that problem, but then I
    noticed antoher nasty feature of multicolumn listbox.
    More serious problem with this structure is, that if tester 2 have more
    values than tester 1, multicolumn listbox shows only same amount of
    values than what tester 1 have and rest of values are lost in
    kyberspace, because in multicolumn listbox values can be added only
    places where already are values or to last row +1. Do anyone have any
    ideas how to prevent this or how I should build my VI so I could create
    test list for testers?

    hi Janne.
    it took me a while to get back
    sorry!
    good to know u have been able to solve it!
    anyhow, do look this vi  i have attached.  This also takes care of extra elements in the larger array and appends them into the interleaved list box entry.
    hope it can be of help to u.
    ciao

  • How to read 'clicked header' AND selected row from multicolumn listbox?

    I have a multicolumn listbox filled with 6 columns and about 500 rows.
    I want the user to be able to click on a column header, and sort the listbox alphabetically on that column. I've written the code for that, and that works. (using the 'itemnames' en 'get clicked col hdr' properties.)
    However, I also want to include the option, that when a user highlights a row, and then clicks on the header, that after the listbox gets sorted it scrolls down to the selected row.
    (So that the user doesn't have to search for it)
    And that's where things go wrong, because the value of the listbox changes to zero when you click on a column header. No I idea why it does that, but it's rather
    annoying. Can I change that behaviour somehow?
    Or any ideas how to get around it?

    My thanks to you and Jared.
    Seems I got a working solution now.
    Did take a while to figure out why your solution worked. Basicly, you're reading the row from a few iterations before.
    As soon as I understood that, I simplified it a little. Look at the attached file... I think it does the same. :-)
    Jared asked for the sorting routine. As I don't seem to be able to attach files when replying to comments, I took the liberty to include it here also.
    Basicly, I just use the 'sort 1D array' that comes with Labview 6. To be able to sort a 2D array, I convert every row to a cluster. That's something the 'sort 1D array' VI can handle nicely.
    To sort on the correct column, I just cut all columns in front, and paste them behind again. A
    fter sorting, I reverse the process.

  • How to write into multicolumn listbox during runtime?

    Hi,
    I am able to edit into multicolumn listbox. But i am not able to write into empty boxes... How to do that???
    Regards,
    Amit

    Hi Amit,
    Have you initialised the item names with any default values? If not try initialising the item names to a 2D size that will be large enough for you're requirements. Once this size is set in edit mode you can't enter data at runtime outside of this initialised area.

  • Is there a way to extract data from one of e.g. 7 rows from the multicolumn listbox?

    is there a way to extract data from one of e.g. 7 rows from the multicolumn listbox?

    All the data can be extracted by creating a property node and read the Item Names property...then you get a 2D array of all the rows and columns. Wire that array into an index array function and input the row you want (e.g. the listbox value, if you want the row currently selected...)...that's it. See attached example.

  • Problem extracting value from reference

    Hi all,
    I have a main VI where the user specifies a range for acquiring data. These values are then passed to a subVI which iterates a loop an according number of times. I have created a reference in the subVI which passes the position of the data acquisition in the range specified as I want to provide a progress bar which would be calculated as (max value - current value)/(maxvalue - minvalue).
    I created an indicator to show the current value on the main VI which is related to the reference I created and when I run the main VI I can see this value changing correctly. The problem is that I cannot find a way to wire this value into the formula above. I tried changing the indicator to a control, but the value is not passed.
    I have attached my code along with the subVIs to illustrate the problem. Current Frequency A increments correctly on the screen whereas Current Frequency B stays constant. I have also tried using local variables, property nodes and an OpenVIReference Node but none of these solve the problem.
    I'm sure this must be possible so if somebody could tell me the correct way to go about it then that would be much appreciated :-)
    Many thanks,
    Ian

    No worries - I managed to solve my own problem.
    I realised if I did the calculation and created the progress bar on the subVI and made the reference straight to that then it wouldn't required the need to bring a wire from the reference.
    Still, I'd be intrigued to know if I could've done it the other way tho...

  • CSV from Multicolumn Listbox

    Currently, I have a User Input Promt delivering values to a Multicolumn Listbox. 
    I need, when a value is True (externally from the while loop), for the multicolumn listbox to spit out the top cued value as a Comma Seperated Value (CSV) string.
    Example:
    1. External value is true
    2. Upper most row of values from listbox taken and placed into CSV string
    3. String sent out of while loop (external)
    Thank You,
    Jim

    CSV from Multicolumn Listbox.vi ‏64 KB

    Which part are you having problems with, since it's not clear:
    Accessing the first row - You already have the 2D array in the loop, so not sure why you would want to pull the data from the listbox, as that's been formatted to 2 decimal places, so you'd lose accuracy.
    Converting to a comma-delimited string - Use the Array to Spreadsheet String function. See attached pic for example.
    Getting notified of this external value - This depends on what's generating this external value. You can use a queue, or a simple global.
    Tip: You should separate the handling of the Stop button from the handling of the button to add a row. In your implementation if you click Stop you're forced to see the dialog to enter a value, even though you're trying to stop.

  • How to get selected value from a listbox

    Hi !
    I use following code to fill in my LISTBOX with values :
    AT SELECTION-SCREEN OUTPUT.
      val-key = 1.
      val-text = '0016'.
      APPEND val TO list_values.
      val-key = 2.
      val-text = '0028'.
      APPEND val TO list_values.
      val-key = 3.
      val-text = '0035'.
      APPEND val TO list_values.
      val-key = 4.
      val-text = '2001'.
      APPEND val TO list_values.
      val-key = 5.
      val-text = '0515'.
      APPEND val TO list_values.
      CALL FUNCTION 'VRM_SET_VALUES'
        EXPORTING id     = 'p_list'
                  values = list_values.
    My question is - how to get a selected key/text value ? i dont need it to be done dynamically - i just need it in START OF SELECTION to perform tasks.
    Thx in advance.

    Unfortunetly it does not work
    i Define parameter as follows :
    PARAMETERS:
      p_list AS LISTBOX VISIBLE LENGTH 10.
    Then i add values to it :
    AT SELECTION-SCREEN OUTPUT.
      val-key = 1.
      val-text = '0016'.
      APPEND val TO list_values.
      val-key = 2.
      val-text = '0028'.
      APPEND val TO list_values.
      val-key = 3.
      val-text = '0035'.
      APPEND val TO list_values.
      val-key = 4.
      val-text = '2001'.
      APPEND val TO list_values.
      val-key = 5.
      val-text = '0515'.
      APPEND val TO list_values.
      CALL FUNCTION 'VRM_SET_VALUES'
        EXPORTING id     = 'p_list'
                  values = list_values.
    Then when i add a blank section :
    AT SELECTION-SCREEN ON p_list.
    I set a breakpoint in START OF SELECTION block - but the value is empty no matter what do i select.
    Actually when i select value from the list and hit enter key on selection screen the selection in a listbox goes empty :/
    Whats the cause of this ?
