Can't get a figure (chart) from LabVIEW to TestStand report

Hello
I've got a problem concerning getting a figure from a measurement. The code itself works, when I run it from LV it asks for the file name and there are no errors.
The thing is, the chart doesn't show anything. The line (PXI1Slot2/ai0) is a valid line that works (I've triple-triple checked it with MAX).
Also, I did get a figure from it, but I made the stupid mistake of not making a back-up before modifying the LV. What's funny is that I've reconstructed the LV to its working state (to the state before I started messing with it), and it doesn't work. I've tried to reload the LV, and "Unload all modules" in TestStand. Neither works.
I'm really a n00b with LV, so keep that in mind when givin' me feedback.
I've attached the LV I'm using. Any input would be appreciated.
Thanks

I have thought about evaluating the Boolean data in TestStand but, as you say, this is a lot of work. What I have been doing is to map the boolean data to integers in LV (very easy) and then use the multiple numeric step type to evaluate the integer array automatically. This feels kludgy and I have tried a couple of times to create a "multiple boolean" step type with little success. I'm surprised TS hasn't anticipated a test returning multiple pass/fail results. I do this all the time for production code.
What I have tried is to copy MultipleNumericLimitsTest data type to a custom type and add a BooleanArray with a data type Array of Boolean[0..empty]. Then when I specify module, I select Step.BooleanArray as the value. The last step (that I know of) is to select Step.BooleanArray as the data source in the edit limits window. At this point if I run the test, I get the error "expect numeric, found boolean" (or something similar). When I look at the properties of my custom step type, the Substeps has DoMultiNumericMeasEvaluation as the Post-Step. I believe this is the root of my problem but I can't figure out how to change this to "DoMultiBooleanMeasEvaluation" or similar. Any Ideas?

  • How can I pass in continuous value from labview to teststand?

    Hello
    I want to run a vi using teststand. I want this vi to send values to teststand. My problem is that the value is only updated at the end of the vi execution and I want to get the value before the end of the vi execution. If somebody can help me ...
    Thanks
    Corentine 

    Corentine,
    you can think of TestStand calls to LabVIEW-VIs just like functioncalls in C/C++. The main continues running only if the subroutine is fully executed. Furthermore, LV returns values to the parameters (connector block) only at the end of the execution of the VI.
    So you cannot use "simple VI calls" in your sequence if you need datatransfer during execution from steps. If you like to do something like this, the easiest way would be to create a VI which runs continuously in the background and supplies data via mechanisms like Queues (if executed in the same instance) or TCP/IP. In the stepmodules you can retrieve the data when needed.
    hope this helps,

    Yes, I did try to go on my settings>wifi and was waiting for any wifi signals to pick up, but nothing shows up. But on my PC I get a whole list of networks to choose from. Regarding my neighbor, I already have her password that is why I was able to get it on my PC, the problem is that the mini Ipad is not picking any signal neither can it locate me when I go to maps.

  • How can i get the all values from the Property file to Hashtable?

    how can i get the all values from the Property file to Hashtable?
    ok,consider my property file name is pro.PROPERTIES
    and it contain

    how can i get the all keys & values from the pro.PROPERTIES to hashtable
    plz help guys..............

    The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
    InputStream is = new FileInputStream("tivoli.properties");
    props.load(is);

    You don't use Airplay.  You set up Home Sharing on both and under the Computers section of AppleTV you'll then find it under Movies (or Rentals if rented), assuming it's in a compatible format.

  • How can I get the "text" field from the actionEvent.getSource() ?

    I have some sample code:
    import java.awt.*;
    import java.awt.event.*;

    import java.util.ArrayList;
    public class JFrameTester{
         public static void main( String[] args ) {
              JFrame f = new JFrame("JFrame");
              f.setSize( 500, 500 );
              ArrayList < JButton > buttonsArr = new ArrayList < JButton > ();
              buttonsArr.add( new JButton( "first" ) );

              panel.add( buttonsArr.get( 1 ) );
              panel.add( buttonsArr.get( 2 ) );

              public MyListener() {}
              public void actionPerformed( ActionEvent e ) {
                   System.out.println( "hi!! " + e.getSource() );
                   // I need to know a title of the button (which was clicked)...
    }The output of the code is something like this:
    hi! javax.swing.JButton[,140,5,60x25,alignmentX=0.0,alignmentY=0.5,
    border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource@1ebcda2d,
    flags=296,maximumSize=,minimumSize=,preferredSize=,defaultIcon=,disabledIcon=,
    disabledSelectedIcon=,margin=javax.swing.plaf.InsetsUIResource[top=2,left=14,bottom=2,
    right=14],paintBorder=true,paintFocus=true,pressedIcon=,rolloverEnabled=true,
    rolloverIcon=,rolloverSelectedIcon=,selectedIcon=,text=first,defaultCapable=true]
    I need this: "first" (from this part: "text=first" of the output above).
    Does anyone know how can I get the "text" field from the e.getSource() ?

    System.out.println( "hi!! " + ( (JButton) e.getSource() ).getText() );I think the problem is solved..If your need is to know the text of the button, yes.
    In a real-world application, no.
    In a RW application, a typical need is merely to know the "logical role" of the button (i.e., the button that validates the form, regardless of whether its text is "OK" or "Save", "Go",...). Text tends to vary much more than the structure of the UI over time.
    In this case you can get the source's name (+getName()+), which will be the name that you've set to the button at UI construction time. Or you can compare the source for equality with either button ( +if evt.getSource()==okButton) {...}+ ).
    All in all, I think the best solution is: don't use the same ActionListener for more than one action (+i.e.+ don't add the same ActionListener to all your buttons, which leads to a big if-then-else series in your actionPerformed() ).
    Eventually, if you're listening to a single button's actions, whose text change over time (e.g. "pause"/"resume" in a VCR bar), I still think it's a bad idea to rely on the text of the button - instead, this text corresponds to a logical state (resp. playing/paused), it is more maintainable to base your logic on the state - which is more resilient to the evolutions of the UI (e.g. if you happen to use 2 toggle buttons instead of one single play/pause button).

  • How can I get the context-parm from a web.xml file using struts?

    Hello:
    I need get the context-param from the web.xml file of my web project using struts. I want configurate the jdbc datasource connection pooling here. For example:
    <context-param>
    <param-name>datasource</param-name>
    <param-value>jdbc/formacion</param-value>
    <description>Jdbc datasource</description>
    </context-param>
    and then from any Action class get this parameter.
    Similar using a simple server can be:
    /** Initiates new XServlet */
    public void init(ServletConfig config) throws ServletException {
              for (Enumeration e = config.getInitParameterNames(); e.hasMoreElements();) {
                   System.out.println(e.nextElement());
              super.init(config);
              String str = config.getInitParameter("datasource");
              System.out.println(str);
         public void doPost(HttpServletRequest req, HttpServletResponse res)
              throws ServletException, IOException {
              // res.setContentType( );
              System.out.println("Got post request in XServlet");
              PrintWriter out = res.getWriter();
              out.println("nada");
              out.flush();
              out.close();
    but only this works for init-params, if I use
    <servlet>
         <servlet-name>MyServlet</servlet-name>
         <display-name>MyServlet</display-name>
         <servlet-class>myExamples.servlet.MyServlet</servlet-class>
         <init-param>
         <param-name>datasource</param-name>
         <param-value>jdbc/formacion</param-value>
    </init-param>
    </servlet>
    inside my web.xml. I need something similar, but using struts inside the action class for that I can get the context-params and call my database.
    Thank you

    To get context parameters from your web.xml file you can simply get the ActionServlet object from an implementing action object class. In the perform (or execute) method make the following call.
    ServletContext context = getServlet().getServletContext();
    String tempContextVar =
    context.getInitParameter("<your context param >");

  • How can I get the XML structure from a flat structure?

    Hi all,
    in my XI SP 12 I use a JMS adapter to read information using the WebSphereMQ transport protocol.
    The structure that I receive have this format:
    <Name_A.KeyFieldValue><Name_A.fieldName_A1_Value>...<Name_A.fieldName_AN_Value>
    <NumberRecordType_B><NumberRecordType_c>
    <Name_B.KeyFieldValue><Name_B.fieldName_B1_Value>...<Name_B.fieldName_BN_Value>
    <Name_B.KeyFieldValue><Name_B.fieldName_B1_Value>...<Name_B.fieldName_BN_Value>
    <Name_C.KeyFieldValue><Name_C.fieldName_C1_Value>...<Name_C.fieldName_CN_Value>
    <Name_C.KeyFieldValue><Name_C.fieldName_C1_Value>...<Name_C.fieldName_CN_Value>
    the problem is that in this structure each line is not separated by a carriage return or a comma, I have all the information in a single line:
    <Name_A.KeyFieldValue><Name_A.fieldName_A1_Value>...<Name_A.fieldName_AN_Value><NumberRecordType_B><NumberRecordType_c><Name_B.KeyFieldValue><Name_B.fieldName_B1_Value>...<Name_B.fieldName_BN_Value>...<Name_B.KeyFieldValue><Name_B.fieldName_B1_Value>...<Name_B.fieldName_BN_Value><Name_C.KeyFieldValue><Name_C.fieldName_C1_Value>...<Name_C.fieldName_CN_Value>...<Name_C.KeyFieldValue><Name_C.fieldName_C1_Value>...<Name_C.fieldName_CN_Value>
    and the customer don't want to insert a line separator.
    Then, the question is:
    How can I get the XML structure from this structure?
    If possible, I don't want to develop new Module and add it in the JMS Module Sequence.
    PS I have already read the article "How to Use the Content Conversion Module with the XI 3 J2EE JMS Adapter.pdf" and it doesn't seem to help me.

  • How Can I get multi column values from dynamic search help?

    Hi Gurus;
    I'm using dynamic search help in my program.
    I want to get multi column values from search help. But I dont know solution for this issue.
    I'm using F4IF_INT_TABLE_VALUE_REQUEST FM.
    How Can I get multi column values from dynamic search help?
    Thanks.

    Believe it or not, the same FM worked for me in a dynpro. I will try to explain here how it works in custom screen and then you can do your work for other screens or program types. I am not going to write my actual work but will explain in general.
    I have 4 fields (FLD1, FLD2, FLD3, FLD4) and i made the search based on FLD2 and when user click on a line (could be any field), then this would bring the line on to the screens.
    There are like 3 steps.
    You have your value_tab for my fields FLD1, FLD2, FLD3 and FLD4. This is just the data that we pass into the FM. (data: IT_VALTAB type table of ZVAL_TABLE)
    Next map the screen fields into an internal table (data: It_dynpfld type table of dselc ). I also have other internal tables defined  (just to keep it straight, i will be putting here) data:  It_return type standard table of ddshretval.
    Next step is to call the function module. Make sure you have values in IT_VALTAB.
    call function 'F4IF_INT_TABLE_VALUE_REQUEST'
    exporting
            retfield        = 'FLD2'
            value_org       = 'S'
          tables
            value_tab       = It_VALTAB
            return_tab      = It_return
            dynpfld_mapping = It_dynpfld
          exceptions
            parameter_error = 1
            no_values_found = 2
            others          = 3.
        if sy-subrc <> 0.
          message id sy-msgid type sy-msgty number sy-msgno
          with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
        else.
          perform get_selected_fields tables It_return.
        endif.
    The code within the perform GET_SELECTED_FIELDS  - We need to map the result fields after user selects it. The code goes like this. This is step is to update the dynpro fields.
    I need a internal table as well as a work area here. like,
    data: lt_fields type table of dynpread,
            la_fields type dynpread.
      field-symbols: <fs_return> type ddshretval.
    so fill out LT_FIELDS from the IT_RETURN table
    loop at lt_return assigning <fs_return>.
        la_fields-fieldname = <fs_return>-retfield.
        la_fields-fieldvalue = <fs_return>-fieldval.
        append la_fields to lt_fields.
        clear: la_fields.
      endloop.
    Call the FM to update the dynpro
    call function 'DYNP_VALUES_UPDATE'
        exporting
          dyname               = sy-repid
          dynumb               = '1002' "This is my screen number. You could use 1000 for selection screen (hope so)
        tables
          dynpfields           = lt_fields
        exceptions
          invalid_abapworkarea = 1
          invalid_dynprofield  = 2
          invalid_dynproname   = 3
          invalid_dynpronummer = 4
          invalid_request      = 5
          no_fielddescription  = 6
          undefind_error       = 7
          others               = 8.
      if sy-subrc <> 0.
        message id sy-msgid type sy-msgty number sy-msgno

      endif.
    good luck

    How can I get audio to play from my TV when using hdmi cable?  Video looks great, just no sound.
    I've tried plugging the hdmi into the TV directly and the receiver.
    I get video every time.  HBO to Go , Xfinity, ABC, Youtube, etc...
    just no audio.  Any suggestions? 
    I've tried starting the apps then plugging in the hdmi cable.
    I never tried this before I upgraded to IOS 5.

    Claudiamil-
    I had not tried it with mine since upgrading to iOS 5, so I just did.  I'm using a small Vizio HDTV.  I did not try YouTube, but did try several videos and musical numbers.  In all cases there was sound, including stereo when the source had it.
    I assume you are getting sound from the iPad when the adapter is not connected, so the volume is not turned down.  Dah*veed's suggestion to reset may be what you need.

  • When creating a book how can I get all the photos from an album to show up in the order they were in the album?

    When creating a book in iphoto, how can I get all the photos from the album I want to use to show up in the order that they are in the album?  When I tried to use the option to add my own photos instead of having the program "flow" them, they showed up all mixed up.

    iPhoto puts them in the book in chronological order.  So to get your photos from an album into an iPhoto book in the same order you will need to use the Photos ➙ Batch Change ➙ Date menu option and set them all to the same date with a 1 minute time difference between each.
