How to get all items under a parent item in a tree control

Hello,
I have 2 questions regarding a tree control:
1) Is there any way to specify a parent item tag and get an array of ALL its sub item tags? For example, in the attached vi, specify the Parent#2 parent tag and get an array containing Item#P21 and Item#P22
2) Is there a way to specify a range to the ActiveCell property. For example, all items from line#1 to line number#3
Any ideas?

 Did you try a search? There's no direct way of doing this. You have to navigate the tree and build up an array. You can find an example here: http://forums.ni.com/t5/LabVIEW/get-all-children-o​f-a-parent-in-tree/td-p/729548
2) Is there a way to specify a range to the ActiveCell property. For example, all items from line#1 to line number#3
No. (It's called ActiveCell, not ActiveCells) Presumably you are trying to perform an operation on multiple items. Unfortunately, you need to use a loop. You should defer panel updates if you're doing this a lot.

  • How to get all users under an organizations?

    Hello everyone.
    Just want to know if anyone knows how to get all users under a particular organization.
    From the Search User form, I found they may kind of user such attribute conditions:
    MemberObjectGroup
    is in
    XXXX(organization)
    But unfortunately, the "is in" is not a valid AttributeConditionOperator, so besides using "recursive" self-written function, anyone knows any possible buit-in trick?

    Here is my solution:
    <Rule'>
        <RuleArgument name='organization'/>
        <RuleArgument name='context'/>
        <block>
            <defvar name='orgs'>
                <new class='java.util.ArrayList'/>
            </defvar>
            <invoke name='getChildObjectGroupNames'>
                <invoke name='getObject' class='com.waveset.ui.FormUtil'>
                    <ref>context</ref>
                    <s>ObjectGroup</s>
                    <ref>organization</ref>
                </invoke>
                <ref>orgs</ref>

                <map>
                    <s>conditions</s>
                    <list>
                        <new class='com.waveset.object.AttributeCondition'>

  • How to get all kind of GP work items for all users

    Dear all:
       Basing GP implementation,we can only get the single user's work item. Is that possible to get all of the users' work items,and can filter the work item via time field?
      thanks a lot.

    ISearchResult result=UMFactory.getUserFactory().getUniqueIDs();
                   IUser iuser;
                   while(result.hasNext())
                        iuser=UMFactory.getUserFactory().getUser(result.next().toString());
    The above code retrives all the users from the UME
    IGPUserContext context = GPContextFactory.getContextManager().createUserContext(iuser);
    IGPWorkItem[] workitems = GPProcessFactory.getRuntimeManager().getWorkItems(GPWorkItemStatus.getTypeForCode("1"), context);
    You will get the WorkListItems in the workitems array. The type for code which is 1 currently, must be changed according to the requirement. It is different for Completed, Inprogress Tasks, etc.
    Hope this will help you!

  • How to get access to Row Data (Child Text) in a Tree Control Pragmatically?

    In LabVIEW 2010, I have entered Row Data into a Tree Control pragmatically using the Add Item method and providing the Child Text array and the Child Tag for the Row. When a Row in the Tree Control is selected, I can get the Row Tag in the Value Property of the Tree. But how do I access the Child Text array data when the Row is selected? I can't seem to find a Tree Control Property or Method that will return that data back again.
    What I am trying to do is: once a Row in a Tree is selected and a button is pushed, if the Row Tag is valid, I want to transfer all of the Row data into another similarly formatted Tree. To do that I need the Row Data for the Tree and Row that was selected. I can not find a way to get access to this Row Data after it has been entered into the Tree.
    Can anyone tell me how to pragmatically access the Child Text or Row Data in a Tree Control from a selected Row in the Tree? I have the Tag for the Row, but how do I access the data?
    Thanks for your assistance.
    Solved!
    Go to Solution.

    As mentioned in the posting here, you can use the Active Item:Tag property to set the item to which subsequent property changes apply. This includes pulling the Active Celltring values out in a for loop as you increment the Active Cell:Active Column Number to get the row's Child Text data programmatically as I was originally wanting to do.
    Note that wiring a 0 to the ActiveColNum property and reading the String value will return the tree item's visible name (in column 0), but not the unique item Tag (which is somewhat intangible after its creation). Therefore, I save the unique item tag when I add the item to the tree control (the output of the Add Item invoke node) and store it as a separate column of the Child Text array and place it out of sight in the tree control so I have access to it later. It might be useful, it might not.
    I find the tree control totally non-intuitive and not well explained anywhere, but that's how a lot of LabVIEW coding is I guess. Play with it long enough and you become an expert. I had to learn the hard way, but I hope this helps someone else.

  • How can I get all options under edit in iPhoto to appear and revert in red, the only option it gives me is to select multiple

    how can I get all options under edit in iPhoto on my phone to appear it has revert in red on theleft side & done on the right side, the only choice it gives me is select multiple

    The usual cause of that issue is a corrupted or missing font that Firefox replaces by another, in this case a bold, font.
    As a test you can try to disable the default font and choose a few different fonts (Arial, Verdana, Tahoma, Times New Roman) to see if you can identify the culprit.<br />
    you will have to reinstall that corrupted font.

  • The user acct my apple was connected to no longer works (corrupt).  My Apple TV is still synced to that account and all of my recent purchases are going to that username.  Does anyone know how to get all of the purchased items back and to the new user?

    The user profile my appleTV was synced on my computer to no longer works (corrupt).  My Apple TV is still synced to that profile and all of my recent purchases are going to that username.  Does anyone know how to get all of the purchased items back and to the new user (same computer)?  I created a new user on my computer and moved the itunes folder to the desktop but never changed the path to which the apple synced to.  Now I can only see old items I purchased before the user profile went bad.  PLease help!

    Welcome to the Apple Community.
    Changing the library the Apple TV is synced with will delete all synced content from the Apple TV, but it won't delete purchased content.
    You should be able to change the library, resync any content you want and transfer your purchases back to the new library.

  • I changed my apple ID and lost everything. How do I get all my apps and purchased items back?

    I changed my apple ID and lost everything. How do I get all my apps and purchased items back?

    Content and Apple IDs -
    Content is forever tied to the Apple ID that bought it. Apple does not transfer content from one Apple ID to another. Apple does not merge Apple IDs. You will never be able to access your content bought with one Apple ID with a new Apple ID.

  • How to get all the values from the dropdown menu

    How to get all the values from the dropdown menu
    I need to be able to extract all values from the dropdown menu; I know how to get all those values as a string, but I need to be able to access each item; (the value in a dropdown menu will change dynamically)
    How do I get number of item is selection dropdown?
    How do I extract a ?name? for each value, one by one?
    How do I change a selection by referring to particular index of the item in a dropdown menu?
    Here is the Path to dropdown menu that I'm trying to access (form contains number of similar dropdowns)
    RSWApp.om.GetElementByPath "window(index=0).form(id=""aspnetForm"" | action=""advancedsearch.aspx"" | index=0).formelement[SELECT](name=""ctl00$MainContent$hardwareBrand"" | id=""ctl00_MainContent_hardwareBrand"" | index=16)", element
    Message was edited by: testtest

    The findElement method allows various attributes to be used to search. Take the following two examples for the element below:
    <Select Name=ProdType ID=testProd>
    </Select>
    I can find the element based on its name or any other attribute, I just need to specify what I am looking for. To find it by name I would do the following:
    Set x = RSWApp.om.FindElement("ProdType","SELECT","Name")
    If I want to search by id I could do the following:
    Set x = RSWApp.om.FindElement("testProd","SELECT","ID")
    Usually you will use whatever is available. Since the select element has no name or ID on the Empirix home page, I used the onChange attribute. You can use any attribute as long as you specify which one you are using (last argument in these examples)
    You can use the FindElement to grab links, text boxes, etc.
    The next example grabs from a link on a page
    Home
    Set x = RSWApp.om.FindElement("Home","A","innerText")
    I hope this helps clear it up.

  • Get all children under root

    I want to know whats the easiest way to get all children under root. Say, if the depth is 100, how can I get the all the children from depth 1 to depth 100? Does java has an API?
    Thanks.

    Hi,
    You are not seeing the DR elements because you haven't traversed to them yet. Doing a getChildren on the Param element only returns you its first level children. You need to either recursively invike getChildren() on each of the param's children or call getDescendants once on the param element whichever suits you best.
    You can do as follows:
                 SAXBuilder builder = new SAXBuilder();
                 builder.setValidation(false);
    // use a fileinputstream in place of stringstream
                 InputSource is = new InputSource(stringStream);
                 document = builder.build(is);
                Element element = document.getRootElement();
                if(element.getName().equalsIgnoreCase("PARAM"))
                    List l=element.getChildren();
                    Iterator listIterator=l.iterator();
                    int j=0;
                        while(listIterator.hasNext())
                        Element paramelem =(Element)listIterator.next();
                        if(paramelem.getName().equalsIgnoreCase("DETAILS")) {
                            List einfo = paramelem.getChildren();
                            Iterator einfoIter = einfo.iterator();
                            while(einfoIter.hasNext())
                                Element einfoElem =(Element)einfoIter.next();
                                if(einfoElem.getName().equalsIgnoreCase("DR")) {
                                    String errCode = einfoElem.getText();
                                    System.out.println(" errcode " + errCode);
                        }Hope this helps.

    Configure audit settings.
    Configure audit settings => Data and Items => specify events to audit.
    Under specify events to audit. Select all the available options.
    Could you please answer my following questions?
    What are the recommended guidelines from Microsoft to use audit reporting for collaboration site specifically. More in terms of which settings to be enables for logging considering disk
    space usage.
    If we want to select all options under document and items section for auditing what are the recommendations from Microsoft to implement it. Mire in terms of infrastructure enhancements
    to accommodate the additional log space requirements.

    It's always very relative how much space to reserve for audit logs on SharePoint. It depends on so much factors... Only you can decide what is the best practice for your environment.
    A sharepoint farm should be well maintained as per :

  • How to create multiple BOM of same parent item?

    Hi All,
    Please guide me, How to create multiple BOM of same parent item? I tried but system throws a message as same Parent Item already exist in the table. I am afraid if system supports this functionality or not?

    Hi,
    You are welcome.......
    Well the exact process would be as I mentioned in my previous post.
    1. Create the BOM for an item
    2. Choose this item in the Production Order
    3. Then in this Production order you can change/ delete/ add whichever item you want .
    OR
    If all the child items are completely different from the original BOM then you can use the Special Type BOM in which you can always create the BOM while creating the Production Order itself. There is no standard BOM here.
