Vector or ArrayList  use for dropdown with more than 1000 entries

Hi Friends
I am having more than 1000 entries of different TimeZone's which i need to display in a dropdown list.
i am not able to decide whether i need to use a Vector or Arraylist for storing these values.
please let me know which one will be best suited to use in case the list entry is more than 1000 characters.
waiting for a positive reply from your side.
Thanks & Regards

A JComboBox can be constructed from a Vector (rather than any other sort of List) without having to implement your own ComboBoxModel. (JList is similar).
I agree with kajbj - a control like this with a thousand entries is rather poor interface design. One exception might be if the entries are sorted in some way, and you "jump" to the appropriate place in the list as the user types.

  • Error occurs when executing an item in an inbox with more than 1000 entries

    Hi Everyone,
    One of our approvers in SRM experienced an error when his inbox contained more than 1000 entries .  Further execution on any inbox item produces errors.
    Would you know where to set the maximum allowable entries in a user's inbox? Can this be set thru SRM config or Basis functionality?
    We also searched for existing SAP Notes but found nothing.
    Your inputs and help are greatly appreciated.
    Thanks and Regards,

    The user has sent me the screen shot. But this has no error messages. The approval transaction shows an ITS screen/code with template 'bbpapproval/99/saplbw02_1200.html'
    However, we have a user in Quality where the page displays with no problem and with 1675 Entries.
    Do you think this is more of an ITS setting or any Template/JavaScript issues?
    I got this code (view source code) earlier today and the topmost header of the code is:

    Regarding the not-so-good practice of approvers to have more than 1000 entries in their inbox, we are still in the process of planning on how to divide the task to different approvers since there is only one approver (Project Manager) for the related network.
    Thanks and Redards,

  • How to pass more than 1000 entries in 'IN' clause, Oracle 11g

    Hi All,
    I know this is a very common question in Oracle discussion forum. But, Im in different zone.
    I use C#, .NET and Oracle 11g. I have a situation where I will create a query statement using 'IN' clause in C# code based on my requirement and execute that statement from code itself with oracle connection object. I do not have any procedures. I must phrase my query statement and pass it on to OracleConnection object to execute it.
    My code looks like this....
    List<decimal> x_Ids = new List<decimal>();
    I will load my IDs into x_Ids here;
    string whereInClause = ........I will prepare a 'IN' clause (All IDs separated by ',')
    My query would looks like this....
    string query = select * from MYTABLE where X_ID in [ whereInClause with more than 1000 entries]
    I have a workaround with OR operator with 'IN' clause like below.
    X_ID in [ Ids till 1000 entries] OR X_ID in [Next 1000 entries] OR X_ID in [Next 1000 entries] on.....
    It is working, but, I heard that this may slowdown the performance of the application. Is this really a performance hit to my application?
    Can you please suggest any other workaround to overcome this situation?

    I have a workaround with OR operator with 'IN' clause like below.
    X_ID in [ Ids till 1000 entries] OR X_ID in [Next 1000 entries] OR X_ID in [Next 1000 entries] on.....
    It is working, but, I heard that this may slowdown the performance of the application. Is this really a performance hit to my application?There should be no performance difference between a statement like
    select * from myTab
    where ID in (1,2,3,4,5)
    OR ID in (6,7,8,10,12) and
    select * from myTab
    where ID in (1,2,3,4,5,6,7,8,10,12) The execution plan should be identical.
    However those values might better be send as a single object (collection or table of numbers type).
    I think the ODP or OO4O connectivity allows to create and such oracle object types.
    Another way could be to think about how all the values are created? Did any user enter them manually? Certainly not. Then maybe you can apply the same logic to the SQL statement that created those values in your .Net application.
    something like
    select * from myTab
    where ID in (select t2.FK_ID from otherTab t2 where t2.Col1 = 100) This approach would probably beat all others performancewise. Since you avoid the overhead of constructing the in-lists.

  • Can you get an Apple ID for corporate use to associate with more than 10 devices?

    Can you get an Apple ID for corporate use to associate with more than 10 devices?

    I don't believe you can. The usual model for iOS app distribution is for each device to have a unique Apple ID and for apps to be acquired separately, either via codes from the Volume Purchase Program or individual purchase through the iTunes Store. The licensing from the iTunes Store doesn't allow an app to be installed on more than one device unless all the devices are being used by a single person, so you legally cannot install one app on multiple corporate devices in the circumstances most businesses use.

  • How can i use my iphone with more than one itunes

    how can i use my iphone with more than one itunes

    Sync iPod/iPad/iPhone with two computers
    Although it isn't possible to sync an Apple device with two different libraries it is possible to sync with the same logical library from multiple computers. Each library has an internal ID and when iTunes connects to your iPod/iPad/iPhone it compares the local ID with the one the device normally syncs with. If they are the same you can go ahead and sync...
    I have my library cloned to a small 1Tb USB drive which I can take between home & work. At either location I use SyncToy 2.1 to update the local copy with the external drive. Mac users should be able to find similar tools. I can open either of the local libraries or the one on the external drive and update the media content of my iPhone. The slight exception is Photos which normally connects to a specific folder on a specific machine, although that can easily be remapped to the current library if you create a "Photos" folder inside the iTunes Media folder so that syncing the iTunes folders keeps this up to date as well. I periodically sweep my library for new files & orphans with iTunes Folder Watch just in case I make changes at one location but then overwrite the library with a newer copy from the other. Again Mac users should be able to find similar tools.
    As long as your media is organised within an iTunes Music or Tunes Media folder, in turn held inside the main iTunes folder that has your library files (whether or not you let iTunes keep the media folder organised) each library can access items at the same relative path from the library folder so the library can be at different drives/paths on different machines. This solution ensures I always have adequate backups of my library and I can update my devices whenever I can connect to the same build of iTunes.
    When working with an iPhone earlier builds of iTunes would remove any file not physically present in the local library, even if there was an entry for it, making manual management practically redundant on the iPhone. This behaviour has been changed but it will still only permit manual management with a library that has the correct internal ID. If you don't want to sync your library between machines on a regular basis just copy the iTunes Library.itl file from the current "home" machine to any other you want to use, then clean out the library entries and import the local content you have on that box.

  • Help! We have a form with more than 200 entries and when I looked at it yesterday it had one! When you download the form to excel they all show up. However, when I added another record today it disappeared. Can you tell me what's happening? I've been usin

    Help! We have a form with more than 200 entries and when I looked at it yesterday it had one! When you download the form to excel they all show up. However, when I added another record today it disappeared. Can you tell me what's happening? I've been using adobe forms for 2 years with mass response feedback and have never had this problem.

    I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
    At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
    The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
    I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
    You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
    Good Luck - Cheers,

  • PDFA 1b Dictionary with more than 4095 entries

    I am trying to create a PDFA 1b complaint document using a word document.  Acrobat does create a PDF A document but when I try to verify complaince with PDFA 1b using the preflight option it reports error as " Syntac problem: dictionary with more than 4095 entries".  How do I solve this problem?

    Sorry for the split, but the editor messes up the code if I post such a long message.
    The APPLY CHANGES button triggers an event I catch in the following way:
    FORM user_command USING r_ucomm LIKE sy-ucomm
                      rs_selfield TYPE slis_selfield.
    * Calculate sel_lines.
      DATA ref1 TYPE REF TO cl_gui_alv_grid.
          e_grid = ref1.
      CALL METHOD ref1->check_changed_data.
      CASE r_ucomm.
        WHEN  'ZAPPLYCHANGES'.                
          REFRESH mod_lfa1.
          LOOP AT it_lfa1 INTO wa_lfa1 WHERE sel = 'X'. "to get a table of the modified rows
            APPEND wa_lfa1 TO mod_lfa1.
    Here I can see that the ZZVMDCUI field is not changed for every line, even if I have modified it. And also, SEL gets always the value of the FIRST LETTER (obviously, since it's a flag) of the ZZVMDCUI modification I made.
    This sounds to me that actually my report see the SEL flag as the only 'editable' field; I can write contents in another editable field but the only modified one is just SEL (which is the first).
    Can you please give an hint on that ? Thanks in advance

  • Can i use my ipod with more than one computer?

    i synched my ipod with one computer, hooked it up to another and it says i can't sync with more than one library? it says i have to restore it but i dont want to delete my music off of my ipod, i just want to add the music from this other library

    I have two different iPods and two computers. I regularly use either iPod on either computer.
    First set the preferences so itunes will not automatically sync when ipod is connected.
    Then connect the ipod and set itunes to manually manage music.
    Drag and drop whatever content you want to the device showing on the left.
    If this was the default setup, there wouldn't be all these posts about people losing all their music when they connect their ipod.

  • IN operator with more than 1000 values

    For a given list of IDs (PKs), I need to fetch the corresponding rows.
    The problem is that I have more than 1000 values and as far as I know that IN operator is limited to 1000
    I thought about using UNION such that each Select contains up to 1000 IDs.
    select * from temp where id in(1....1000)
    union all
    select * from temp where id in(1001....2000)
    Is there a better way to do that?

    As others have presented technical solutions, i'll present you a logical one (seemingly logical anyways, but it will depend on your application).
    I have seen some applications where you get
    select * from some_table where ... <conditions>;That result set is returned to the front end and presented to the users who then pick a series of records and submit another request to the database which ends up being...
    --note, this could be a many table join, with lots more information that just the some_table, this is illustrative only
    select * from some_table where pk_value in (super_super_duper_list_based_on_last_result_set);If this mimics what you have in your application, i'd recommend just fixing it so the users can select a reasonable set of data, OR the entire set (in the last case you'd just send the <conditions> instead of a massive list of PK values).
    Again, highly speculative but i thought i'd mention it in the off chance it's useful to you.

  • List with more than 1000 elements

    I'm trying to use this query:
    select *
    from street
    where street_cod in ('street_code_list')
    It working well when the 'street_code_list' has less than 1000 codes but it fails when it have more, with a message that says that a list can't have more than 1000 elements. How can I fix this problem? Can I use any other kind of object to store my list?
    I'm querying the database in ColdFusion using ODBC.
    Thank you in advance,

    Another thing to consider doing is simply creating a "list table" which would contain your list elements and allow you to do a
    FROM Y
    FROM Z)
    type query.
    I don't know where you are getting your list from, but if it is persistant (i.e, doesn't change with every program run) this is certainly a viable option (and may be usable even if the list does change every run).
    If this is being executed in PL/SQL (or some other procedural language) you could also just loop through your list: execute the query with the first 1000 list elements and do your processing, then the next, and so on. Of course, to some extent this depends on your processing, but if you need the entire result set before you can process it, then you could store the individual result sets in a PL/SQL table or an array (if you are using Pro*C or whatever) and then process when the PL/SQL table/array was fully populated.

  • To display text field with more than 1000 length in ALV

    Hi Friends,
           I need to display material long text field which is more than 1000 length in ALV or Object oriented ALV.
    Please help me to resolve the issue.

    U mean to say in a single cell of ALV ??
    It is not possible in ALV .. As per OSS note 857823
    Below is the reason for same.. I think you should to split in number of columns.
    Entries in cells of the type CHAR or string are truncated after 128 characters in the SAP GUI.
    Other terms
    ALV Grid Control (cl_gui_alv_grid), function module (Full-screen)
    Grid (Reuse_alv_grid_display, SAPLSLVC_FULLSCREEN), SAPGUI, back end, front end
    Reason and Prerequisites
    The data table that is sent to the front end only allows character values with the length 128.
    This is the standard system behavior and cannot be changed.

    I would like to know if there is any way to correct this error. If it happens because memory is too small, how could it be increased?

    Hi Diana
    As far as I know, standard SAP has restricted the no. of line items in an accounting document to 999.
    So, this is in turn impacts the no. of line items you can have on a Sales invoice,
    Since every invoice  line item can have atleast 2 accounting entries, the max. no. of  invoice line items you can have is 499.
    I dont think there is no work around for this
