Enum with arbitrary values

Is it possible to define an enum with arbitrary values as in the following C line :
enum { MINE = 5, YOURS = 12 }
oz

Hi OZ,
No, it is not possible in LabVIEW 6.0.2 or lower.
I have read that it can be done in CVI and then exported to LabVIEW. If I had to guess I would probably say it was Jeane-Pierre Droilet (?sp), or Dr. Scott Hanna (?sp), or Rolf Kalbermatter (?sp) who posted a method for accomplishing this task.
If you are interested in finding out how this was done I suggest you use Brian Renken's Search engine at
http://www.searchview.net/
to find the posting (it was posted in 2000 or 2001 I think). I believe they are called "sparse enum's".
If you want to accomplish a similar functionality with pure "G" you could use a translator type sub-VI. The translator would use the use the enum value to index an array of constants that has the "Sparse-enum"s you want returned.
An advantage of this method can be realized if the translator is implemented as an action engine where the "indexed-array" is read from an un-initialized shift register. This would allow redifining the enums "on-the-fly.
I hope this helps,

  • Populating select list in a JSP with enumeration values

    I'm working on a JSP in which I need to populate a select list with enumeration values.
    Everytime I'm trying to insert these values (using enum.nextElement()) in a select box only the first enumerated value gets inserted correctly, the rest of the values shows up outside the select list. I would appreciated any help...thanks!!!

    I'm not exactly sure how your generating your list to begin with, however the following code will work:
    <form>
    <select>
    <%
         java.util.Vector v = new java.util.Vector();
         for(int i=0;i<12;i++){
              v.addElement(new Integer(i));
         java.util.Enumeration enum = v.elements();
         while(enum.hasMoreElements()){
         Object obj = enum.nextElement();
         out.println("<option name='"+obj+"'>"+obj+"</option>");
    %>
    </select>

    BTW does anyone know why the greater than symbol never renders properly in these forums when text is encapsulated in the code tag?

  • NFS4: Allow client to create files with arbitrary uid and/or gid

    Hello.
    I've got a ZFS, which is supposed to be used for storing backups of client machines. I've set:
    --($ ~)-- zfs get sharenfs data/backup/winnb000546
    NAME                     PROPERTY  VALUE                                                 SOURCE
    data/backup/winnb000546  sharenfs  ro,root=winnb000546:10.0.4.5,rw=winnb000546:10.0.4.5  localOn winnb000546, I can then mount and access this directory. "root" can also create files (eg. "sudo touch $mountpoint/file") and this file is then owned by root:root (0:0).
    But this directory is supposed to hold a backup of the client machine; we don't use NIS or LDAP and thus /etc/passwd and /etc/group don't match. As winnb000546 is a Linux system (Arch Linux, to be exact), it would be somewhat hard to set it up so, that passwd/group completely match anyway.
    Now, as said, it's supposed to be for backup and thus I need to retain the ownership information exactly as it was on the client system. But it doesn't work...
    --($ /mnt/server/data/backup/winnb000546)-- sudo touch file
    --($ /mnt/server/data/backup/winnb000546)-- sudo chgrp hal file
    chgrp: changing group of `file': Invalid argument
    --($ /net/winds07-bge0.win.ch.da.rtr/data/backup/winnb000546/oink/UIDs/nfs3)-- getent group hal
    hal:x:82:askwarIt failed, because the Solaris server doesn't have a group with gid 82.
    What do I need to do on the Solaris 10 server, so that it allows the client to create files on the NFSv4 export with arbitrary gid and/or uid values (ie. even with values it knows nothing about)?

  • Ring with string value

    I would like to know if there is a way to make a single control (either a ring or otherwise) where a string that is displayed to the user has a string as its output value.
    For instance, I have a power laser with a serial communication port and the command to turn on the laser diodes is LASER1;
    I want to display the string "DIODES ON" to the user, but have the control provide the value "LASER1;" when selected.
    This is easy to do with two controls, for example, I can have an enum with the user display strings and a matching enum with the laser command strings, but then I have to ensure that any change affects both controls.
    If it is a single control, it is less likely to have an error when a change is made.
    Any help is greatly appreciated.
    I am using LabView 2009
    Solved!
    Go to Solution.

    Perhaps I should have been more clear.
    There are approximately 20 commands to be sent to the laser from which the user can select.
    Each string to the user has a corresponding command.
    Since this is programmatic for automatic operation; as well as single commands for manual operation, I would like to have a single control with 20 strings and corresponding commands.
    For example:
    User                 Laser
    Diodes On         Laser1;
    Diodes Off         Laser;
    Mode Current    Opmode0;
    Mode Power      Opmode1;
    Gate Open        Gate1;
    Gate Closed      Gate0;
    A single button or a caption string is not adequate.

  • JDBC MS Access--- cannot extract entry with null value with data type Meta

    I'm trying to extract a data entry with null value by using JDBC. The database is MS Access.
    The question is how to extract null entry with data type memo? The following code works when the label has data type Text, but it throws sqlException when the data type is memo.
    Any advice will be appreciated! thanks!
    Following are the table description and JDBC code:
    test table has the following attributes:
    Field name Data Type
    name Text
    label Memo
    table contents:
    name label
    me null
    you gates
    Code:
    String query = "SELECT name, label FROM test where name like 'me' ";
    ResultSet rs = stmt.executeQuery(query);
    while (rs.next())
    String name = rs.getString("name");
    rs.getString("val");
    String label = rs.getString("label");
    System.out.println("\t"+name+"\t"+label);
    catch (SQLException ex)
    System.out.println(ex.getSQLState());
    System.out.println(ex.getErrorCode());
    System.out.println("in sqlexception");
    output:
    C:\Temp\SEFormExtractor>java DBTest
    yet SELECT name, label FROM test
    null
    0
    in sqlexception

    The question is how to extract null entry with data type memo?Okay, what you need to do is this:
    if (rs.getString("val") == null)
      // do something
    }This way, when it's a null value, you can check it first, and then handle it how you want, rather than getting an exception.

  • Need help with NULL values in Crosstables

    Hello everybody,
    I need some help with NULL values and crosstables. My issue is the following:
    I have a query (BW - MDX-Query) that gives me turnover measures for each month. In Crystal Reports I choose crosstable to display this whereby I put all month in columns and all turnover-measures in rows. Each month that has a value (measures are not empty) is chown in the crosstables rows. So far so good. The problem occures when there are month that actually have no values (measures are empty). In that case these months are not chown in columns. But I need CR to display these columns and show the value 0. How can I do that?

    Hi Frank,
    Cross tab shows the data based on your column and these column fields are grouped and based on the group it will show your summaries. 
    If there is no data for any of your group it will not display that group.  In this case you will have to create a standard report which should look like cross tab and to get zero values you need to write formulas .
    Example if you want to display Moth wise sales :
    if Month() = 01 Then
    sum() else 0
    Now this formula will check if your month is Jan, then it will sum up the values else it will display zero value. 
    This is possible only through standard report not with Cross Tab.
    Thanks,

  • Dynamic action with set value on date field

    Hi,
    I'm using APEX 4.02
    I'm trying to calculate the age based on the date of birth dynamically on a form. I'm trying to do this with a (advanced)dynamic action with set value.
    I'm able to get this kind of action working based on a number field etc, but NEVER on a date field.
    I've read all posts on this subject but so far no solution. Even if I try to simply copy the value over to another date field or typecast it to a string ( to_char function ) it does not work. So for me the problem seems to be in the source field being a date field.
    I've tried using the source value as is in a select statement :
    select :P33_GEBOORTEDATUM from dual;
    and also type casted based on the date format :
    select TO_DATE(:P33_GEBOORTEDATUM,'DD-MON-YYYY') from dual
    but still no luck.
    On the same form I don't have any issues as long as the calculation is based on number fields, but as soon as I start using dates all goes wrong.
    Any suggestions would be greatly appreciated. If you need any extra info just let me know.
    Cheers
    Bas
    b.t.w My application default date format is DD-MON-YYYY, maybe this has something to do with the issue .... ?
    Edited by: user3338841 on 3-apr-2011 7:33

    Hi,
    Create a dynamic action named "set age" with following values.
    Event: Change
    Selection Type: Item(s)
    Item(s): P1_DATE_OF_BIRTH

    Fire on page load: TRUE

  • How to get all parameter names along with their values in stored procedure which is being executed

    Im using sql server 2012, is there any possible way to get all the parameters of a stored procedure along with the values passed to it.
    I need these things to build a xml. I mean this should happen in the procedure which being executed and it should be common for all the procedures.
    For example, let us suppose we have to procedures,
    uspSave, @name='test' @age=20
    uspDelete @id=2
    now in uspSave procedure, i need to get @name, @age and the values 'test', 20 and in uspDelete, i should get @id with value 2.
    For getting the column names, i tried this,
    select parameter_name from information_schema.PARAMETERS where specific_name=OBJECT_NAME(@@procid)
    now is it possible to loop through the result of above query and can we get the values.

    I think  you need running SQL Server Profiler to capture this info even in SQL Server 2012.

  • Problem with offset values

    Hi Experts,
    I have a problem with offset values. I have create a variable on OFISCPER, it's characteristic value, indivdual value, mandatory and ready for the input. I need to show the varibel period and the l previous period and so on till 12 periods. I used the offset values (-1, -2, etc.) but when I execute the query I can show just the variable period and the period previous I don`t see. The query is based on multiprovider and don´t has filters. Can anyone help me?

    Leonel,
    You may nt need to have 12 columns in the query designer.
    You could include the keyfigure and restrict it to the variable and create the offset for the 12 periods

  • How to call a dialog program with return value in another dialog program

    Dear All,
    How can I call a dialog program with return value from another dialog program?
    Regards,
    Alok.

    Hi Alok,
    You can you SET/GET parameters to do this.
    This is some information about this.
    To fill the input fields of a called transaction with data from the calling program, you can use the SPA/GPA technique. SPA/GPA parameters are values that the system stores in the global, user-specific SAP memory. SAP memory allows you to pass values between programs. A user can access the values stored in the SAP memory during one terminal session for all parallel sessions. Each SPA/GPA parameter is identified by a 20-character code. You can maintain them in the Repository Browser in the ABAP Workbench. The values in SPA/GPA parameters are user-specific.
    ABAP programs can access the parameters using the SET PARAMETER and GET PARAMETERstatements.
    To fill one, use:
    SET PARAMETER ID pid FIELD f.
    This statement saves the contents of field f under the ID pid in the SAP memory. The ID pid can be up to 20 characters long. If there was already a value stored under pid, this statement overwrites it. If you double-click pid in the ABAP Editor, parameters that do not exist can be created as a Repository object.
    To read an SPA/GPA parameter, use:
    GET PARAMETER ID pid FIELD f.
    This statement places the value stored under the pid ID into the variable f. If the system does not find any value for pid in the SAP memory, sy-subrc is set to 4. Otherwise, it sets the value to 0.

  • GR Value is not matching with PO Value while posting good receipt.

    Hi Experts,
    My client has raised the PO with accounts assignment category K (COST CENTRE) with material description.
    but he has received invoice receipt before good receipt.while invoice receipt he has entered wrong value for some qty as per PO intially and cancelled that wrong entry.
    I have gone through original & cancelled invoice document accounting entries. below is entries:
    Original invoice document accounting entries:
    GR/IR Clearing account: Debited
    Vendor account: Credited
    during cancelling the above document it should be vendor acc is debited and GR/IR account is credited but in the system below entries taken place
    Cancelled invoice document accounting entries:
    Vendor account : Debited
    GR/IR Account : Credited
    Consumption Account : Credited
    Why consumption acc taken place here. pls help what are the possibilitis....
    these entries affecting good receipt value means while taking goods receipt for some qty out of full qty value is not matching with PO value.
    but while cancelling the  GR documents system taking correct values as per PO. Please help.
    Kindly help in this regards
    Regards
    Mohan

    Hi,
    Check the Credit Memo document whether G/L tab is there & whether any G/L account is entered ?
    I think instead of cancelling the MIRO document they might have posted a vendor credit memo manually by specifying a consumption GL.

  • Problem with checkbox value and app.settings.getSetting()

    Hello everyone.
    I`ve got a problem with getting saved settings for checkbox.
    Saved settings doesn`t apply on checkbox value.
    It`s strange, but it always "true".
    So here piece of code:
    checkMe = 11;    //any value for the first time running
    if (app.settings.haveSetting("savea", "chck")) {                           
                          checkMe = app.settings.getSetting("savea", "chck");  // get saved value, else 11
                          alert("checkMe = "+checkMe)
                        if(checkMe == 11){
                            checkMe= false;   //if there is no saved settings, checkbox value will be false/ unchecked
                            alert("You run this script first time, so manual value will be 'false'")
                            }else{
                                checkMe = app.settings.getSetting("savea", "chck");     // if saved settings exist, get true or false
         alert("Yes, checkMe will = "+checkMe)       
    win.checkPanel.chkOne.value = checkMe;  /// checkbox value will equal saved checkMe
    var fff = win.checkPanel.chkOne.value;  // string for alert
    alert("aha! but checkbox value is  = " +fff+ "\n Why so?")     // here we`ve got always "true"
    win.checkPanel.chkOne.onClick  = function () {
        var path11 = win.checkPanel.chkOne.value;  //  checkbox value to variable
        app.settings.saveSetting("savea", "chck", path11);  //saving checkbox value
        alert("Saved this value - " + app.settings.getSetting("savea", "chck"))
    win.checkPanel.chkOne.value is always true.
    Can someone exmplain why and how to get rid of this static value?
    P.S. just in case, here is full code:
    function mainFun()
        this.windowRef = null;
    mainFun.prototype.run = function()

    Played around with different values, combinations...
    Doesn`t work too:
    checkMe = 111;    //any value for the first time running
    if (app.settings.haveSetting("333", "check")) {                           
                          checkMe = app.settings.getSetting("333", "check");

                    if(checkMe == 111){
                             win.checkPanel.chkOne.value= false;
                            }else{
                                if (checkMe != false){
                                win.checkPanel.chkOne.value= true;
                                }else{
                                win.checkPanel.chkOne.value= false;
    win.checkPanel.chkOne.onClick  = function () {
        var path11 = win.checkPanel.chkOne.value;
        var path12 = path11.toString();

  • How to set an attribute of a HTML tag with a value in the Servlet

    I have a HTML page and a Servlet.
    The HTML page sends a request to the Servlet.
    The Servlet has to read the contents of the HTML page. When the Servlet encounters the body tag it should set the bgcolor attribute of the body tag with a string(For eg.a string called color with a value blue) in the servlet.
    After doing this the Servlet has to update the original HTML page with the changes (in the body tag).
    I need a help on this.

    Hi sangee,
    you could get what you want to do by using a Java Server Page instead of both a HTML page and a Servlet.
    I should code something like this:
    <%Strung color="yourColor"%>
    <html><head><title></title></head>
    <body bgcolor="<%=color%>
    </body>
    </html>
