Populate updatable drop down list based on files in the folder path

Hi, 
I am a beginner in labview. I am stuggling on where to start.
Here's what I need to do. 
I want to create an updatable drop down list. It can be automatic upon opening the program or manually update by clicking an update button. The drop down list will list all the filenames that are in .cvs format. These files are stored in a folder path.  Insider the folder, they are stored in different subfolders, the drop box should be able to find those files inside the subfolders. Once the user select a filename from the list, the program will read the data inside that file and import into an array so I can display the data. 
I have an idea on how to display the data, but I don't how to populate the drop down list based on the files in the folder, make it updatable and then import that user selected file's data into the the array. 
Can anyone help me with this? 
Thanks, Ruth

Yup, ListFolder with a pattern of *.csv.  Then use a property node on a combo box or ring to set the items in the drop down.  Here is some free training if you are interested in learning more general LabVIEW tools.

  • How do I populate a drop-down list from a schema variable

    I'm a novice programmer and new to the LiveCycle environment. I need help to populate a drop-down list in LiveCycle from a hard coded variable within my form's schema. I have a list of 28 names (the number of names and actual names change annually). That list is used over 30 times within a form for different selections. Since the list rarely changes, I would prefer to hard code it and make changes to the schema when they occur.
    If I can't find a solution, I will be updating over 30 separate drop-down list objects each time there is a change to the list.
    Thanks in advance for any help
    Chris

    Can you post your schema to [email protected] and I will have a look. You will also need to indicate which node in the schema is supposed to populate the dropdown.

  • Drop-down list won't work at the bottom of a page

    I'm having a problem in my forms with drop-down lists that are situated at the bottom of a page. When the list drops down, only the first few values can be chosen. Any that fall too far down the list, and thus hover over top of the next page, cannot be selected. In this situation, the scroll bar for the list actually scrolls the entire document. Very weird. Has anyone expreienced this before? Perhaps I'm making a simple mistake.

  • Populate a drop down list with data from Excel and fill in a text field, based on drop down selectio

    Hi!
    I have a problem with a PDF form: There's a drop down list that I populate with Excel data that I've put in an XML file through an XSD file -- no problem here. The drop down list has a data binding to the XML file, so that a choice in the drop down list can be associated with an object in the XML file. So, when I make a choice in the drop down list, a corresponding object value is fetched from the XML file and put in a text field on the form.
    How to do this is described by Stefan Cameron here:
    http://forms.stefcameron.com/2006/07/29/dynamic-properties/
    There's a snag, though, and to describe it more clearly:
    The XML file contains three types of objects: role, role number, and role cost center. Of these I use the first and the third, i.e. the role and the role cost center. The drop down list contains the roles, and when I select a role, the corresponding cost center is filled out in the text field. So far, so good!
    But -- if the cost center has the same value for two or more roles, all of these roles "bounce back" into the drop down list, that is, they are all selected in the drop down list. How many of these you can see depend on the height of the drop down list -- if it's low you'll only see the first one.
    If I modify Stefan Cameron's data in his example I get the same behavior, so the problem seems to have to do with how XML data are fetched.
    I'm sure there's a workaround, but I can't find it! I've spent many hours browsing the web without finding anyone with a similar problem.
    Any suggestions appreciated!

    Although your issue is far beyond mine, I was hoping you can help me out.....

  • Drop down list based on log in username - php mysql

    I have a drop down list of client names on a php page that filters a second drop down list of site names.
    At the moment, any user who logs in can see the entire list of clients, however I want to filter the list based on their username log in.
    This is the entire page code, the section in bold is the drop down list in question:
    <?php

    function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) {
      // For security, start by assuming the visitor is NOT authorized.
      $isValid = False;
      // When a visitor has logged into this site, the Session variable MM_Username set equal to their username.
      // Therefore, we know that a user is NOT logged in if that Session variable is blank.
      if (!empty($UserName)) {
        // Besides being logged in, you may restrict access to only certain users based on an ID established when they login.
        // Parse the strings into arrays.

    I think I need to amend the sql statement to something like this - but I haven't quite got it right:

    Where do I drop the code for the colname info?
    name:colname
    type: text
    default value: -1
    run time value: $_SESSION['MM_Username']
    Thanks!

    I don't do PHP but it would be something like:
    $sql = sprintf (SELECT DISTINCT * FROM qry_test WHERE username = %s GROUP BY client_name ASC, $_SESSION['MM_Username'] );
    or you can just embed the session variable into the sql string.
    But why are you using the GROUP BY clause? If you just need a distinct list of names, use the DISTINCT keyword and reduce your select list to only the needed column.

  • How to Populate a drop down list using the values of a text field?

    Hi,
    I wanted to Populate the items of my drop down list according to the value entered in the textfield above it?
    also the value of list remains consistent in other rows also where i am using the drop down list field.
    Please Try to help me in this query.
    Thanks in Advance!!!
    I am using Javascript in adobe version ES 8.2.

    Part II:
    If you have other items for your droplist(s) that are to appear in addition to the "variable language" entered by a user you can add that to the script.  For example in addition to the Party1 and Party2 name appearing in my droplist I also want the list to have an option for a user to select: The parties jointly.  I add this to the script:
    this.addItem(Party1.rawValue);
    this.addItem(Party2.rawValue);
    this.addItem ("The parties jointly");
    If you have trouble making it work, post a bit of your actual form requirements.

  • How to populate page drop-down list in Struts from action?

    I have following mockup JSP:

    aaa,2,str2
    aaa1,1,str3
    aaa1,b,str4
    and I have to show this in the page as a drop-down list of values that are represented in this String[] array returned from Struts action.
    Should action return result array in original ActionForm submitted to the action by this page or should it just put the array into request or session? I need an example if possible
    Many thanks,

    Hi,
    In ur Action Class create aa ArrayList of LabelValueBean Object (use import org.apache.struts.util.LabelValueBean; )
    Eg:
    ArrayList myList  = new ArrayList();
    for( int i=0; i<10 ; i++ )
       myList.add( new LabelValueBean(  "Label of  "+ i , " value of " +i  ) );

  • Populating 2nd drop down list based on the selection of the first using Access DB...

    I have a form that I would like to have the user select the first drop-down list as populated from a data source, but them have the subsequent selection choice dependent on the first. For instance, if they select "administration" for their division, the department numbers shown in the second box would only contain those with "Administration" listed as their division. I have all of this information in my Access table.
    I've seen this possible by storing all of the information in a script. i.e.- listing each division and department. The only problem is that we have over 300 departments and making any changes would be very tedious in an in-form script. Is there any way to have this automatically reference a table in Access?
    Thank you,
    Mike

    In the current version of the portal, it is not possible as you cannot do code-behind on postbacks. If you want more flexibility, you need to write your own front-end that uses the FIM Service webservices...

  • Problems with drop-down list: old references still in the model

    Hi,
    I am getting in troubles with a drop-down list. I configured it as dynamic list and I specified a RFC to get the values. Sometimes when I edit the field  I get that the configuration for the dynamic list is lost and I have to specify again the call to the MF. I did this for a couple of times and my surprise is that the old references are still in the source code. I realized of that when I used the alias manager. The old reference were there with ENUM....To check if the old references are called I switched on the flash debug console and I show that the MF is called a lot of times...
    Anybody knows how to eliminate these old reference???'  One the collateral effects is that the first value of the list is always shown.
    Antonio

    Hi Antonio, hi Marcel,
    the OSS-ID is 0000337147/2007 and the final given answer from SAP was:
    <i>Dear Customer,
    finally I managed to repreduce your problem,
    and it's a bug.
    we will aim to fix it in next releases, and the new Flex 2.0 runtime
    should handle this case, once it will be availible.
    Regards,</i>
    So it might be fixed with the actual SP, but I don't know that for sure (I rather doubt it, to be honest).
    Best Regards,
       Benni
    PS: You might avoid the problem of re-defining the entry list, by defining it as a global entry list, not a dynamic. However, the top-most entry will still be shown!

  • Populate drop-down lists based on check box selections

    Hi. I'm creating a Service Work Order form. At the top, there are several check boxes for the various services we provide, under that , more text fields, drop downs and checkboxes to elaborate on those services, and then at the bottom, fields for pricing.
    I'd like the top half of the form to drive the pricing info that is available or that auto-populates at the bottom.
    Ideally, I'd like to make the pricing specific based on 3 things:
    the service checkbox
    the client
    and the details on that service
    For example:
    If Client XYZ wants Service A that includes subservice B
    $123 should show up on the bottom half in the field for that service
    If Client ABC wants Service B that includes subservice C
    $456 should show up on the bottom half in the field for that service
    Does that make sense?
    I've been unable to get code to work in either the calculate and pre-Open options
    I first tried calculate and used this code (which was just a guess on my part)
    if (CheckBox1 == 1) and if (CheckBox9 == 1) then
    $.rawValue = 50
    elseif
    (CheckBox2 == 1) and if (CheckBox9 == 1) then
    $.rawValue = 50
    elseif
    (CheckBox5 == 1) and if (CheckBox9 == 1) then
    $.rawValue = 55
    elseif
    (CheckBox6 == 1) and if (CheckBox9 == 1) then
    $.rawValue = 55
    elseif
    (CheckBox7 == 1) and if (CheckBox9 == 1) then
    $.rawValue = 50
    elseif
    (CheckBox8 == 1) and if (CheckBox9 == 1) then
    $.rawValue = 50
    else
    $.rawValue = 0
    endif
    That didn't do anything but give me an error about "and"
    So I tried putting code in pre-Open:
    // clear the dropdown displayed value and items
    this.rawValue = null;
    this.clearItems();
    // repopulate the items based on the checkboxes
    if(offshore.rawValue == 1)
        this.addItem("$40.00", "offshore_001");
        this.addItem("$45.00", "offshore_002");
        this.addItem("$50.00", "offshore_003");
    if(inland.rawValue == 1)
        this.addItem("$40.00", "inland_001");
        this.addItem("$45.00", "inland_002");
        this.addItem("$50.00", "inland_003");
    I got no error but nothing populated and the drop-down was, in effect, disabled.
    Any help would be appreciated.
    Thanks!

    Gavin,
    This sounds like an issue that is not related to JHeadstart. To simplify the test case, you could create a simple drag-and-drop ADF application without JHeadstart and see if the same problem occurs there.
    Your suggestion that it is related to the where clause seems likely. Please find out what kind of object USER_ENV is, and how it is initialized. Maybe this initialization is skipped when bouncing the application.
    What happens if you perform the query in SQL*Plus, without doing anything about the USER_ENV?
    Maybe you should ask the Oracle Applications discussion forum...
    kind regards,

  • Populate second drop down box based on selection from first drop down box

    Hello, I have a situation involving a drop down box with 9 items to choose from. What I want to do is depending on which of the 9 items the client chooses, this will determine what items are populated in the second drop down boxes (the items in the second drop down box will be mirrored on 9 other drop down boxes).
    For example, my first list box would be titled Review Type and there would be MF, VA, FA, etc. If the MF was selected, then the 10 boxes below (all drop-downs) will be prepopulated with a specifc selection of topics and if they chose VA then another set of topics would be prepopulated.
    Can you please point me out on the proper script to accomplish this? I don't have a xml/data source to connect to so I will be manually inputting the choices.  Thanks!
    Header 1
    Header 2

    I came across a sample of a script that seems to do what I want it to however I can't seem to get it to work all the way through.  It only compiles the items from the 1st case and not the 2nd or 3rd case.  If I click on the 1st case, it will not clear if I click on the 2nd or 3rd case. The items from the 1st case stays static and shows up for other cases.  However if I open the form and click on the 2nd or 3rd case first, it's blank and nothing shows up. Can you please help me out with any fixes to this problem?  Please help!!
    Here's the script:

  • Drop Down List - Setting the Default Selected Item

    I have a drop down list in my application that gets populated by a remote database.  When you select an item from the list, a screen full of thumbnails is populated based on the selection.  We have decided that when the user gets to this component in our air application, that it looks too empty and barren.  All that displays is a drop down list with an empty screen.  So we would like to set a default setting for the drop down list so that when the user gets to this component, a screen full of thumbnails is awaiting them and they can change it if they want.  My first instinct was just to set the selectedIndex property of the drop down list to the value that we want as the default, and that works, but it only changes the label in the dropdownlist, it doesn't actually populate the screen with the thumbnails.  That is because when an item is selected, it has to be commited to the drop down list by a CLOSE event that then sets off the close handler that populates the screen with thumbnails.  So after looking at the documentation, I found that there is a method called closeDropDown that states the following:
    closeDropDown
    method
    public function closeDropDown(commit:Boolean):void
    Close the drop-down list and dispatch a DropDownEvent.CLOSE event.
    Parameters
    commit:Boolean — If true, commit the selected data item.
    When I use this method, nothing happens.  In fact if I add a listener for the CLOSE event, the close event isn't getting fired.  So I am a little befuddled.  The only thing that I can figure is that I am setting the selectedIndex and not the selectedItem before I call the closeDropDown method, and if you look above, the documentation vaguely states that that "If true, commit the selected data item".  Do I need to set the selectedItem and not the selectedIndex?  If so, I am not exactly sure how to do this since I am using a service to populate my drop down list which kind of makes the dataprovider a little unclear to me in the code because it gets replaced by an AsyncListView.  Here is what I have.

    I would really appreciated hearing from anyone who has experience or insight into setting a default for a drop down list and actually forcing it to execute that default selection.  Any thoughts at all would be helpful.  Thanks!

    I don't see your close handler in the code you posted, so if you provided it and I missed seeing it, please forgive me.  I'm a bit unclear on why the open and close of your dropdown list is so critical to your functionality.  It seems to me that the page of data would be tied to the item selected in the drop down (which to my mind is the only purpose for the drop down to be there).  So why do you first need to open and close the drop down, rather than just taking the selected value and doing whatever you'd normally do with it to populate that page?
    What I'm getting at is that I'd expect that page to be a separate component that would just have a property for the selected "thing", and that you could populate it either manually, as I suggested, or through the close handler on your drop down--I wouldn't think that there should be a need to go through the close handler every time.  Even if you don't have it implemented the way I'm thinking, you may want to think about whether you need to go through the close handler every time, or whether you could break it out so that the close handler simply determines which item to select, then jumps to another function that actually does something with the selected value.  That way, you don't have to go through the overhead of opening and closing the drop down if you need to change its value programmatically.

  • Populatin Drop down lists

    Hi - I am new to this forum so I apologize if this question has been posted before.
    I am trying to populate a drop down list where column a1 is the value and a combination of columns a1 and a2 are the display value. Can someone help here?
    I have tried different SQL statements and keep getting an error.
    Thanks
