Searching for an object in a Collection of table

So I have a Collection of table with an object in, the following trace output

(mx.collections::ArrayCollection)#0
  filterFunction = (null)
  length = 1
  list = (mx.collections::ArrayList)#1
    length = 1
    source = (Array)#2
      [0] (Object)#3
        fileName = "belt_002"
        filePath = "/mens/belts/"
    uid = "2EA13990-EEBA-BDD7-8E55-532927494C53"
  sort = (null)
  source = (Array)#2

When you add items to the collection of table I want to check that there is no such thing as an object with the same properties.

So, how can I check that the object above is not already in the table, basically that there is no corresponding file name and filePath?

Thanks for your help

Hello

Try this:

protected function componentsCheckList_changeHandler(event:IndexChangeEvent):void
            {
                if (_secdataProvider.length==0){
                    _secdataProvider.addItem(event.currentTarget.selectedItem);
                    _secdataProvider.refresh();
                }

                var myTemp:String = event.currentTarget.selectedItem.file;
                var arrayLength:Number = _secdataProvider.length;
                var flag:Boolean = false;
                for(var i:int = 0; i < arrayLength; i++)
                {
                    if(_secdataProvider[i].file == myTemp)
                        flag = true;
                }
                if (flag == true){
                    Alert.show("already selected");
                }else{
                    Alert.show("this can be added");
                    _secdataProvider.addItem(event.currentTarget.selectedItem);
                    _secdataProvider.refresh();
                }
            }

  • Search for pictures not in a collection (LR3)

    Is it possible to find any pictures not in a collection?  I want to see if there is any photo that I have not organized yet.

    In the predicates in the Smart Collection canned, there are registrations for the 'collection', "The Collection does not contain", etc.  So one of the possibilities is to set a smart collection with "Collection contains not one" and "Collection contains no b", etc. once for each letter and figure in English.  I don't know if it would work, but I hope that there is a better way...

    I did some looking around, but I apologize if this is a FAQ.

    Thank you!

    Jason

    No right way, but there is a little better.

    That you use a single rule for all the letters, rather than multiple rules for a single letter.

    For example, doe for the Collection does not contain ' a b c and d... z "

    Or, a simpler version, which include only the vowels: doe for the Collection does not contain "an e I o u". " This may fail on certain collections, but usually works in the real world, because most of the words usually contain at least one vowel.

  • the collection of table support

    Hi, I'm trying to create a slideshow with the RSS feeds from flickr. I use a component datagrid to store the images (because of the effects of transition when I add or remove an item from the dataProvider.) I can go through the images very efficiently by simply removing the first element in the collection of table, but then I get to the end and of course the slideshow is none because I deleted everything. is there an easy way for me to just take the first object in the collection of table and move it to the end? I tried photoFeed.setItemAt (object, int); but I don't know how to call on the first object in the collection of table. also, for the int variable I try to use photoFeed.length because I want it move to the end of the array whose length should be the correct number from the beginning of indexation of array to 0.

    Although I can't understand the requirement of moving an item at the end of a slide show, you can use

    var point: Object = photoFeed.removeItemAt (0);
    photoFeed.addItem (item);

    to achieve what you want.

    If you just want to browse the pictures one by one until the end, you just need to use the createCursor API and get a cursor. By calling moveNext on the slider, you move through the collection until moveNext returns false.

  • Need help with search for mdb using DW in ASP.

    Hello

    I'm trying to put in place a db on a Web site search tool using mdb and dw in ASP. have THEY put in place. Tested OK. Have used ms help pages (printed some) and the DW 8 missing manual to:

    Configure and test a connection string to a database and it is fine.

    Set up to search with a single parameter and it tests OK.

    Configure the results page and it tests OK too.

    I can display the search page and the results page by using the toolbar search engine address and local host by IIS installation and this is very good.

    Unfortunately, when I test the search page and use a proper search for the db password, the results page displays very well with the titles of the table, but no data. I am highly dependent on the ease of DW and I'm not much on the code.

    I tried a lot of different things, but there are so many possibilities! I tried GET and POST. I think that the problem is either in the original report send the form data to the server, the mdb data collection or data display in the final table, although it's conjecture. It covers almost all areas. Also I don't know if "repeat" in the table may have something to do with it.

    If anyone can help me with some general ideas on how I can be able to go forward. I was at this point for about a week.

    Thank you very much in anticipation

    OK, you're text field is named "textfield", but the query string you are testing for is called "search". They must be named the same.

    " size="30">

    rsSearch__MMColParam = Request.QueryString ("search")

    I don't know why you are populating the form field with a value of query string. The value does not exist because there is no field named "search". And the sending of the form (EEG) is what creates the query string that uses the results page.

    Rename the textfield object in your 'Search' form and it should work.

  • What is the best way to search for a Datagrid?

    I want to search the installer for a datagrid control.  I did a lot of research but could not come up with a solution of single column.  Can someone give some recommendations on how I can get all the data that is in the datagrid?

    Thank you.

    Dave

    DataProvider of the DataGrid control is always an instance of ICollectionView: ArrayCollection or XMLListColection collection.

    ICollectionView's filterFunction function that would make reference to a function with a signature of the individual:

    private function filter(item:Object): Boolean {}

    }

    When you have assinged this function to the collection of table and do a refresh() on this function to call for each element in the underlying dataProvider. The "item" is current object, the line if you want, in your dataProvider for which this method is called. Now that you have the complete object available you all it's available properties; make all checks you need and return true if you want to keep the line in the filtered list of false otherwise. That's all!

    Flex Builder Help has many examples of such FilterFunction, like google!

    Good luck!

  • Months of searching for numbers on the sheet

    Hello all and thanks in advance.

    I have tabs at the top. DATA (sheet 1), JAN (sheet 2), FEB (record 3), etc. until the end of the year.

    Data sheet will be the months on the left now I want care to go to the form to correct month and takes the total of the column relative to the other leaves and place in the correct cell line. (I've been copy paste, but I know there is an easier way to do this, so I turn to the people who know the numbers unlike my lack of knowledge.)

    On the leaves of the month, I would also like to highlight the line that are sat and Sun.

    Thanks again everyone for their help.

    Rich

    In the material master

    Hi, NN,.

    You will have a Table for each month. Each Table must have a different name. Your summary table lists more than 12 months, then I would say the table name from each month is named with the name of the month AND the year.

    The monthly tables may appear on separate sheets, or the same sheet. The key, as far as the formulae are concerned, is that each Table can be identified by its name.

    The following example includes only the table for April 2016, named "APR 2016", I assumed that the total line will be row 33 on each table of data collection, but wrote the formula to allow the placement of the line totals in other places. The lines for most of the actual days have been hidden and has not been designated, as these labels have no role in the operation of the formula.

    The TOTALS is defined as a footer line. The formula, in the columns showing a value is SUM (a) where 'a' is the letter of the column to be added. (The two values of zero have been entered manually for example).

    The table has a unique formula, entered in cell B3 and filled with right and until the last line for which there is a Table whose name corresponds to the label in column A. For example, the formula has been met only 3 online.

    B3: = INDEX (APRIL 2016: $A$ 1: $ 33, MATCH $N ("TOTALS", APRIL 2016: $A, 0), GAME ($ 1 B, APRIL 2016: $1: $1.0),)

    Syntax:

    INSTRUCTION (range,-l'index of the line, column-index, index of the surface)

    range: all of the cells in the source table

    the index of the line: the number of the start line to get the value. This is provided by the first statement of the GAME.

    the index of the column: the number of the column from which to get the value. This is provided by the second statement to MATCH.

    the index of the surface: omis. By default, 1. There is only 1 area of application of this INDEX, all of the source table.

    MATCH (image search-search for, - where - method)

    EQUIV function returns the position in the list of the search for value.

    First case:

    search for: TOTALS text

    search - where: column A of table source

    method): 0 means finding the exact value.

    Second case:

    search for: the text contained in the cell of line 1 of the specified column. That form is completed on the right, the increments of the column by one for each stage.

    search - where: line 1 of table source

    method): 0 means finding the exact value.

    The formula should be changed for each new line. Three references to "APR 2016" should be changed to match the name of the table to collect this row grand totals. Once edited in column A, the formula can be filled right and automatically adapts to his new position.

    Note: The duration value in column F of the table of the month wouldn't transfer and keep the same formula in column C of the summary table. Any attempt to restore the format to match your example resulted in a triangle of error.

    Kind regards

  • effective method for searching for my computer and its peripherals

    I am very dissatisfied with the tools at my disposal to search for my computer. I'm looking for another product, because Microsoft developers seem to have as objective search of his computer a very difficult task.

    So what third-party products are out there for the research and management of research on his computer?

    Here is an example of a task, I want to perform. I have a directory with pdf files and word files. I have a sentence and I want to find all files to see which files have this single sentence? It is a basic task simple, I'm sure that almost everyone would like to do at some point. This simple task was made more difficult with each subsequent version of windows.

    Here are some tasks I want to do like all the time.

    Look for file names and not the content of the files. searching content of files in file types. Search files with a certain creation, date of modification. all these things are hidden by users and which must be very complex I have a suite of wire run.

  • How to search for extension in the Directory Manager

    Hi, I want to create a directory to handler extension research instead of name search, how can I do this? The basic unit book says you can do this, but does not say how.

    If it is not possible, how can I configure the unit to collect the numbers the caller to input and search for the extension and send to the right destination, if it is an invalid extension, it should return to the main message.

    Thank you.

    The Manager directory for searches in name only - if you know the extension you can just dial it in any home.

    You can dial the extension of a user or a Manager in a call handler or the default greeting Subscriber. so the best way to proceed is to simply dial the extension of the opening home - if it is not valid, you will hear the guest of error and then the opening greeting is replayed.

    If you want to use a different Manager for this and want to make sure after dialing invalid extensions that go you to the greeting for this call handler, update the greeting 'mistake' to go to this Manager instead of opening greeting Manager of appeal. By default the greeting of the error is not visible in the SA - you can make visible by using the advanced configuration tool - or you can do it in BulkEdit if you want, there is a special in there option on the greetings to "loop back to itself" page, which will update all managers or subscribers to have their greetings error restart their own welcome message instead of kicking back to the opening greeting.

  • ActiveDirectory.search - search for unity of ORGANIZATION by DN

    Hi guys,.


    Have a moment by using the AD plugin and the search of the Active Directory object method in orchestrator puzzle.


    In my environment, it is quite possible that there are organizational units of the same name located in different parts of the domain tree... So search and get a specific object to search for something unique, like the DN. However, it seems only you can search for an ORGANIZATIONAL unit by its name, which returns an array of objects.


    One way to alleviate this is to have ouName and ouDistinguishedName as entries in the workflow... but this seems silly.


    Is there a way to search AD by DN to return a specific object or I have to logic impliment to match the output of is var = ActiveDirectory.search ("OrganizationalUnit", ouName) of an input string that contains the unique name?


    Hope someone can shed some light

  • How to search for keywords by synonym (Lightroom CC)

    Hello

    I use a hierarchical keywording for animal taxonomy, it is based on the "official" latin names, vernacular names in different languages are included as synonyms.

    Is there a a way to search for keywords using their synonyms? The search box seems to be limited to the only keyword and don't look for synonyms.

    Thank you

    Chris

    Chris,

    Just to clarify what's doing with LR: when searching by keyword in the filter library bar or with a smart collection, LR search of synonyms. However, as you have noticed, when you use the keywords filter box in the list of keywords, synonyms Panel are ignored.  In addition, you can enter a synonym in the Keywording Panel (if you try it, LR silently will create a new keyword for you).  It seems that LR 2 had the ability to filter the list of keywords by synonyms and use synonyms to apply keywords, but that functionality has been removed in LR 3.

    Please add your vote and opinion on this in the Adobe official feedback forum: Lightroom: search for the keyword by synonym

    My Tag no matter what plugin handles synonyms as you wish, but it was designed for a particular workflow and may not be to your liking.

    the command button is in a fragment of the page, you can perform a search. In your actionListener, you receive the actionEvent object from

    I need help with my script to search for text and remove the hyperlink and characterstyle link which applies (returns the normal text).

    I can't do either as I want.  I want the user to be able to type in a dialog text they want to search for, do search this text IGNORING case (case insensitive) and then for all instances that he find it, remove character styles that are applied to the (set to [none]) and delete the hyperlinks.
