Help!  How to upgrade two dimension collection ArrayCollection?

Hello

I'm having a problem of understanding of documentation on populating a DataGrid of two dimension collection ArrayCollection. My situation is that I have a DataGrid with a bunch of information, currently stored in a two-dimensional array (digital in the first dimension and by field name in the second dimension). I also have a bunch of data streaming from an XMLSocket, which, when it happens, is analyzed, resulting in one of the fields of the table in need of update. I can do very well with the table directly, but I can't try to understand how use the ArrayCollection collection features to cross this two-dimensional structure - setItemAt() does not seem suited for this purpose? I need to trigger the effects on the relevant cell that has been updated, when I round coding, so I will try to use some structure that handles update events and others for me automatically, such as the ArrayCollection collection.

I do not know is still the best technique to use, and the intermediate level (the ArrayCollection collection and others) could be changed completely, so if you can suggest (and illustrate, if she is as confused as this!) a better method, I would be grateful.

Thank you

David

Ah.

You must look for the item in the collection ArrayCollection. This is usually done with a loop in the collection. When you have found the item you would:

Item.Quantity = new quantity;
dp.itemUpdated (item);

You must call the method of collection itemUpdated to make the signal Collection all interested parties (for example, the DataGrid bound to her) she's changed.

A Collection can also views and ViewCursors that might be useful to have a lot of data.

    {
    result = new collection ArrayCollection (event.result as Array);

  • How to browse the collection ArrayCollection?

    I have two datagrids and you want to move items on datagrip and fill the other.  Here is a screenshot of a Visual screen.

    Picture 1.png

    In the screenshot on I can add some names/sex to the datagrid on the left using the text input and the Add button.  I can select the checkboxes for each name of ros as well. I want to do is move the check names in the datagrid control on the left for the datagrid on the right.  4 max.  But if I chose only 2 name, both names would be added to the 1 Racer and Racer 2. Runner 3 and 4 of the race would be left blank.  If I check the new names and submitted it would be in a new line on the left data grid.

    What I can understand is to scroll the datagrid control left and find only the lines of control.  To the right of the datagrid can be quite easily as soon as I figure out how to identify what is checked and what is not checked.

    This is the datagrid on the right.

    "" " < mx:DataGrid x ="10"y ="76"height ="337"id ="list"editable ="false"dataProvider =" rosterArray{}">

    < mx:columns >

    < mx:DataGridColumn headerText = "" width ="30">

    < mx:itemRenderer >

    < mx:Component >

    < mx:CheckBox / >

    "" < mx:DataGridColumn headerText = "sex" dataField ="sex" width = "40" "editable ="false" / >

    "" < mx:DataGridColumn headerText = "time" dataField ="time" width = "45" editable ="false" / >

    < / mx:columns >

    < / mx:DataGrid >

    The function add to my rosterArray (left datagrid) is below.

    private function rosterAdd():void

    {

    rosterArray.addItem({name:addName.text,sex:sexGroup.selectedValue.toString()});)

    addName.text = ""; empty text entry field.

    }

    I guess I have to scroll datagrid and not the rosterArray because I don't have a place for the checkmarks in the rosterArray.

    Any help idetifying which lines are checked in the left data grid would be much appreciated.

    Thank you.

    I don't know how to remove duplicates in an ArrayCollection collection or otherwise.
    But since you already have an XML and require only a text node inside.
    I go through the easiest way.

    Please take a look

    Course 1

    you need to do collection here ArrayCollection instance before put something u.
    this.myDataDistinct = new ArrayCollection();

    E4X selection

  • How to upgrade a shift with two independent loops while register?

    Hello everyone, I have a panel with two clusters with indicators control... a left and a right. I have messages from serial port, and I'm currently updating the left and the right within their own while loops. I have a single variable, which must be updated based on updates on both sides. Basically, I need follow the last selection update on each side... If I had 1, 2 and 4 on the left side and 3 on the right side... I would need to follow 4 was the latest updated the register shift variable for uses more in my vi. Can someone give me an idea how to upgrade this a variable based on two while loops that run independently in the same sequence context? Thanks in advance, cayenne

    Thank you both of you for the suggestion.

    I managed to find a way to get the values that I needed without EI... but I read the link to the Nugget in their subject, and I can't expect a use for them in the future.

  • How to use @sumrange in two dimensions?

    How to use @sumrange in two dimensions? I want to sum up all the values through the period and the time of a measure...

    It does not give the right ratio:
    "WHEELS" / @SUMRANGE ("COGS", Jan:Dec,@RELATIVE(Years,0)); ")

    This gives the right solution, but the year is coded:
    "WHEELS" / (@SUMRANGE ("GEARS"-> "FY12", Jan: Dec) + @SUMRANGE ("GEARS"-> "FY13", Jan:Dec));))

    I want to dynamically reference every year at once.

    Thanks in advance.

    Hello

    Try the @XRANGE function in the @SUMRANGE

    Then

    "WHEELS" / @SUMRANGE ("GEARS", @XRANGE ("FY09"-> "Jan", "FY15"->"Dec"));

    Coding always a little difficult, but you can substitute two variables for ease of maintenance

    Platform swaps are allowed only for the most recent released CS software (CS6).  You can get a version license Mac to CS4 by Adobe since Adobe doesn't sell older versions, and the only version of CS for sale is CS6...  CS4 is not eligible to get CS6 at an upgrade price.

  • String XML collection ArrayCollection, how?

    Hi all

    I am a beginner in Flex 2 and having trouble filling a PopUpMenuButton.

    Data for the menu comes from a Web service as an xml string:
    <>Protocol
    account <>
    < id > 1 < /ID >
    < name > first < / name >
    < / recording >
    account <>
    < code > < /ID > 2
    < name > second < / name >
    < / recording >
    ...
    < / Protocol >

    Context menu button is defined as:
    < mx:PopUpMenuButton id = "AddMenu' label = 'Add' dataProvider ="{protocolList}"= 'name' showRoot = labelField 'false' itemClick ="runAddMenu (event); "/ >

    Result handler is:
    [Bindable] private var protocolList: XML;
    private void gotIt(e:ResultEvent):void {}
    protocolList = new XML (e.result);
    }

    With this configuration the popup appears like:
    Add >
    first >
    1 >
    1
    first >
    first
    second >
    2 >
    2
    second >
    second

    Repeating values where I'm just a right menu.
    I do not use attributes but the node element value of data and that seems to be confusing.

    I thought that the difficulty it is to convert the XML data in an ArrayCollection collection, but I can't get this to work.

    Documentation and examples, I assumed it would be as simple as changing my result handler in order to:
    [Bindable] private var protocolList: ArrayCollection collection;
    private void gotIt(e:ResultEvent):void {}
    var temp: XML = new XML (e.result);
    protocolList = temp. Protocol.record;
    }

    Problem is that gives me a runtime error: unable to compel XMLList for collection ArrayCollection.

    For some reason any 'temp' Gets type XMLList and not XML and I couldn't find a way to do it in XML.

    I know that I can browse the xml tree and building the ArrayCollection collection, but it seems exaggerated as Flex should be able to do it for me.

    I'm something obvious overseeing here?

    TIA
    Julio Carneiro

    Thank you, Tracy, but I ended up iterating over XML data to generate an array to use in the menu. I tried your suggestions before, but the result has always been a hierarchical menu, where it must be flat. Maybe a problem with the help of the element instead of attribute values.

    At the end of the day, it's really simple to do this way, here's my latest code that helps someone else:

    [Bindable] private var protocolList: Array;
    private void loadProtocolsComplete(e:ResultEvent):void {}
    var temp: XML = new XML (e.result);
    protocolList = new Array ({name: "Select", id:-1});
    for each {(var elem:XML in temp.record)
    protocolList.push ({name:elem.name, id:elem.id});})
    }
    addMenu.dataProvider = protocolList;
    }

    I have a Toshiba Windows Vista laptop and I want to upgrade to Windows 7. I have two user accounts and I was just wondering that during the upgrade can I still keep the files that I have on the accounts or they will be deleted? Thank you.

    If you make a way to update your programs and files will be kept. A custom installation will remove your programs and files.

    If you are running Windows Vista , in some cases you can proceed directly to Windows 7, and in other cases, you must perform a custom installation. The following table shows what editions of Windows Vista can be upgraded to Windows 7.

    Windows Vista Home Basic

    Windows 7 Home Premium, Windows 7 Ultimate

    Windows Vista Edition Home Premium

    Windows 7 Home Premium, Windows 7 Ultimate

    Windows Vista Business

    Windows 7 Professional, Windows 7 Ultimate

    Installation - 'upgrade' means what?
    Upgrade means that you can install Windows 7 simply by inserting the Windows 7 upgrade software in the DVD drive of your PC and follow the instructions on the screen. While you are not required to backup and reinstall your files, or reinstall your programs, it is a very good idea to back up your files and settings before you start any upgrade to the software. Get more information on the software updates and best practices .

    Installation - what does "Custom (Clean)" Mean?
    A custom (clean) installation clears the contents of the hard drive of your PC. Your files, settings, and programs will not be transferred to Windows 7. This means that to install Windows 7, you must:

    • Back up any files and settings you want to keep

    • Install Windows 7

    • Reinstall all your files

    • Reinstall all the programs you want to use.

    These four steps take time, skills, techniques and Windows Easy Transfer can help. However, if you are not comfortable with this process, please consider having the installation carried out by a local service provider.
