What is the Easiest way to sequence records in a Interface?

I very simply want to add a sequence number in the Mapping definition to an interface as I process records and write to a simple file. I want to start at 1 each time and process to X.
I would think their should be a reserved word like (rowcount or counter) but for the life of me I can't find it. I would have thought I could have used Variables, but that does not seem on because there does not seem to a way to update them. Looks like a sequence is the only way to go, but then I have to reset it every time and my initial testing indicated it would not increment. But that is probably operator trouble! I would like to know how the experts would accomplish this simply programming feat. ODI is so powerful, why make such a simple thing so complicated?
Thanks

First off, make them learn GridBagLayout as well as the other layout managers (like BorderLayout). Have them play around with JBuilder's visual editor, making note of what changes visually do to the underlying code, etc. It will serve them well.
I have yet to find an "easier" layout manager that doesn't at some point tie your hands and end up making life more difficult. With GridBagLayout, BorderLayout and use of subcontainers, you can do anything you might need. :-)
I wouldn't say absolute positioning is anti-Java.
It's certainly more work to deal with in most cases.
. You can always get the screen resolution and
adjust your sizes accordingly. It's still 100% pure
Java code. It is anti in that it doesn't follow the general spirit of Java. Yes it will be 100% Java code, but it will be at least 90% crap as well. :-) You then can't easily do localization, changes in the look & feel mess up your app, your components won't resize properly, any change to a label's text causes you to have to tweak everything, etc. Ghastly stuff. It is the lazy way to get the GUI to look like someones mock up, but that is all it's good for.
If you run across a GUI done with absolute positioning, you have my permission to give the responsible developer an atomic wedgie.

  • Pusblish Abode Connect meeting records (.flv) over Adobe Media Server - What is the easiest way?

    Hi,
    my name is Robin Schröder. I am a member of the univertity “Hochschule Hamm Lippstadt” from Germany.
    We r using the adobe connect already. We wanna create offline videos of meeting records and publish them over adobe media server. The offline videos are in the .flv format.
    Do I have to convert the .flv into mp4 (h264 & AAC) before streamable with hds and hls?
    I read about f4fpackager that this program can convert .flv into .f4m – but it failed with error 999….. I checked the .flv file with flvcheck before: success!
    The sample Video worked fine.
    So my question:
    We wanna publish all .flv recordings over the Adobe Media Server (VODs). What is the easiest way to achieve this?
    Convert .flv in a streaming format (mp4?) - HOW?
    Create multi-bitrate versions from the video - HOW?
    Create f4m file for adaptive bitrate streaming - manually?
    Publish hds & hls URL in the html site (decryption for url possible?)How can I realize a iPad/iPod/iPhone switch in the html Code for HLS/HDS switch?

  • What is the easiest way to create alias email addresses in exchange 2013?

    For example my official domain is [email protected]
    Within my company i want to make it look like certain departments are sending from bicycles.com skateboards.com
    and skooters.com and receive to those addresses even though the emails are really going through the
    [email protected] domain. but it appears to be coming from three other domains.
    appearance is everything. What is the easiest way to accomplish this.
    Step by step with examples if possible. I am not well versed in exchange server 2013 yet.
    Droid Hacker

    In Exchange 2013 you can use the ECP to add additional email addresses to mailboxes. In order for a mailbox to send using an address, that address needs to be set as the reply address. One mailbox cannot send as multiple addresses. Doing that would require
    a mailbox for each address. To set a new primary address on a mailbox log into the ECP and choose mailboxes under the recipients option on the left. Then search for the mailbox you want to add the address to and click the edit symbol. Navigate to the
    Email Address tab on the left. To set a new primary address you will likely need uncheck the box for "Automatically update email addresses based on the email address policy applied to this recipient". Then click the plus button, enter the new address,
    and check the box for "Make this the reply address"
    Before you do this you should ensure that the proper MS records exist for these other domains, and that they are properly configured for mail flow. Once you set this as the reply address for a mailbox, that is the address external users will use for replies.

  • What's the easiest way to move app data and data structures to a server?

    Hi guys,
    I've been developing my app locally with Apex 4.2 and Oracle 11g XE on Windows 7. It's getting close to the time to move the app to an Oracle Apex server. I imagine Export/Import is the way to move the app. But what about the app tables and data (those tables/data like "customer" and "account" created specifically for the app)? I've been using a data modeling tool, so I can run a DDL script to create the data structures on the server. What is the easiest way to move the app data to the server? Is there a way to move both structures and data in one process?
    Thanks,
    Kim

    There's probably another way to get here, but, in SQL Developer, on the tree navigation, expand the objects down to your table, right click, then click EXPORT.. there you will see all the options. This is a tedious process and it sucks IMO, but yeah, it works. It sucks mostly because 1) it's one table at a time, 2) if your data model is robust and has constraints, and sequences and triggers, then you'll have to disable them all for the insert, and hope that you can re-enable constraints, etc without a glitch (good luck, unless you have only a handful of tables)
    I prefer using the oracle command line EXP to export an entire schema, then on the target server I use IMP to import the schema. That way, it's near exact. This makes life messy if you develop more than one application in a single schema, and I've felt that pain -- however -- it's a whole lot easier to drop tables and other objects than it is to create them! (thus, even if the process of EXP/IMP moved more than you wanted to "move".. just blow away what you don't want on the target after the fact..)
    You could use oracle's datapump method too.
    Alternatively, what can be done, IF you have access to both servers from your SQL developer instance (or if you can tnsping them both already from the command line, you can use SQL*PLUS), is run a script that will identify your apex apps' objects (usually by prefix to object names, like EBA_PROJ_%, etc) and do all the manual work for you. I've created a script that does exactly this so that I can move data from dev to prod servers over a dblink. It's tricky because of the order that must be executed to disable constraints and then re-enable them, and of course, trickier if you don't consistently prefix ALL of your "application objects"... (tables, views, triggers, sequences, functions, procs, indexes, etc)

  • What is the easiest way to restore to a previous backup of Time Machine?

    I was adding some simple album cover artwork to my iTunes collection when the computer locked up. I got the spinning beach ball and was unable to "force quit." So, I did a re-boot using the power key. I then launched iTunes and it opened properly with all the new Album Artwork. The files were not large in size and the "Album Artwork" folder is only 99.8MB.
    I did a Time Machine backup yesterday and the only thing changed on the computer was the artwork. However, when Time Machine launched to do a backup it said there was 30GB(!!!) to back up?!?!?
    I am assuming something got corrupted in the iTunes library file during the crash and now it thinks it has to back up part of the music.
    So, that is what caused the problem. My question is, what is the easiest way to simply restore the backup the Time Machine had completed yesterday before all this happened?? It doesn't seem like there is a simple way to accomplish this. It looks like TM is used to back up specific files or folders and not to restore the computer to a previous state.
    Any help is much appreciated.
    Thanks in advance!!

    Time Machine backs up all files except those you exclude in TM prefs. It doesn't "know" what kind a file is; it just compares info about a file on the source drive to see if it has already been backed up, or if it is new or has changed and needs to be backed up again. For unchanged files or folders, TM simply creates another hard link on the backup drive.
    iTunes artwork files are separate files. The assignments of artwork to particular music files are saved in another file within the iTunes application (which is actually a package, a folder containing other files). So if all you did was add album artwork, TM would back up each new artwork file, and a new copy of the hidden file within the iTunes application containing the artwork-music links.
    The following is speculation on my part, but it seems logical:
    TM uses records in the hidden File System Events log to identify any new or modified files. However, it is possible to have an FSE entry as to a particular file without modifying the file (e.g. open, then close). So TM doesn't "know" until it actually compares the source file with the backup file (if one exists) whether a file is new or has been modified.
    Hope this helps.

  • What's the easiest way to digitize my VHS collection?

    I have a bunch of old VHS video that I want to digitize into VCDs or DVDs. What's the easiest way to do that? Given that VHS are of lower quality, I probably want VCD anyway.
    Equipments I have:
    - PowerBook 12 inch (DVI, 1.33 GHz)
    - VCR
    - bunch of video cable laying around.
    Thanks!
    ERic

    You are going to need some kind of analog video to DV converter.
    Do you have a DV camcorder? If so, you may be able to pass the analog video through it directly to the PowerBook with a FireWire cable and use iMovie to record your tapes. If you have Roxio Toast, you could then easily make some VCDs of your iMovies.
    Another option would be a device like an Elgato EyeTV. Not only could you use it like a TV tuner/TiVo, it can convert your analog video to MPEG files and then, again if you have Toast, you can export your recordings to VCDs.
    There are other kinds of analog to DV converters, someone else may chime in too.

  • I am using Iphoto 11 ver 9.4.3 on mac using oxs 10.8.5 i want to export calendar projects to an external hard drive. what is the easiest way to do this? i have tried export and import but it didn't seem to work.

    I am using Iphoto 11 ver 9.4.3 on mac using oxs 10.8.5 i want to export calendar projects to an external hard drive. my goal is to store them in an external hard drive so it doesn't use up memory on the mac hard drive. is it possible to copy the specific projects without copying the entire library? what is the easiest way to do this? i have tried export and import but it didn't seem to work.

    What do you not understand?
    You can duplicate the iPhoto library (command - D ) and delete everything except the project and its photos from the copy and move that
    Or
    However the calendar takes very little space - it is simpy database entries - it is the photos in the calendar that take space - and for most people you would wnat to keep those photos in your library
    you can use a photo in 50 calendars and it still is only one photo in your library - as I explained calenders do not exist as such - they are simply database entries telling iPhotop how to display the calendar - they take almost no space at all

  • What is the easiest way to create and manage very big forms?

    I need to create a form that will contain few hundred questions. Could you please give me some advise on what is the easiest way to do that? I mean for example is it easier to create everything in Word (since it is easier to manage) and than create a form based on that?
    My concern is that when I will have a very big form, containing different kinds of questions and with many scripts, managing it during work will be slow and difficult, for example adding a question in the middle of the form which would require moving half of the questions down which could smash the layout etc.
    What is the best practise for that?
    Thanks in advance

    Try using Table and Rows for this kind of forms. These forms will have the same look throught with a question and and answer section..
    In the future if you want to add a new section, you can simply add rows in between..
    Thanks

    I have a mid year 2007 24 inch iMac and will be purchasing a new 27 inch Retina iMac, what is the easiest way to transfer the data and files from my old machine to the new one?

    Following up on this thread,
    I have a new iMac on the way and my current is from 2008, never had a problem but I am sure there are internal issues that I would prefer not to transfer.
    I have no issues other then the slowness in certain programs and that is the main reason to buy a new one.
    Programs like numbers and pages seem to take a longer time to open after I update to Yosemite.
    I only use 272GB of 500 GB, my memory is 4GB and I am upgrading to 8Gb and bought the 4.0 processor.
    Question:
    Is there a way to manually transfer items or would that be a waste of time in that if there are issues they could be anywhere and would transfer anyway?

  • What is the easiest way to transfer a large imovie project from one computer to another in a different location.

    What is the easiest way to transfer an faairly large HD imovie project from one computer to another in a different location. Can you export to drop box? Will the other computer need the exact imovie version?

    OK it depends.
    If you have a finished movie, you can SHARE/EXPORT MOVIE and create your final movie. Then, depending on the size of the finished movie, you can transfer via dropbox or similar service. Ninety minutes is a very long movie for iMovie, but it may work for you. I would suggest 720P to keep the size down.
    If you need to transfer the entire iMovie Project so it can be edited in iMovie at the other end, then you need to transfer the project and event assets to an external hard drive and get the hard drive to the other location.
    Directions are here. Follow the directions for 1) Moving or copying Project to external drive. Then 2) Consolidate Media.

  • What's the easiest way to add storage to a mac mini. (1TB hard drive but only 32G of real storage). External device, internal or partitioning?

    What's the easiest way to add storage to a mac mini. (1TB hard drive but only 32G of real storage). External device, internal or is there some way to partition? I tried doing so but received a message that there wasn't enough free space to partition. Seems like a 1TB drive should have more storage than my Ipad

    Its worth confirming what free space you have on your drive: 
    go to:   Apple Menu > About this Mac >  More Info > Storage
    The bar chart shows how much free space there is on the drive:
    Please realise that partitioning does not create extra space so this wont help you.
    If your free space is less than 20 % you should get extra storage with an external USB or Firewire drive, any make or model will work.

  • What is the easiest way to export all tables data from Oracle to MS SQL Server?

    Hello MS,
    I would like to export all tables from Oracle 11.2 to MS SQL Server 2012 R1.
    Using the tool "Microsoft SQL Server Migration Assistant v6.0 for Oracle" did not work for me because there are too many warnings and errors regarding the schema creation (MS cannot know it because they are not the schema designer). My idea is
    to leave/skip the schema creation to the application designer/supplier and instead concentrate on the Oracle data export and MS SQL data import.
    What is the easiest way to export all tables data from Oracle to MS SQL Server quickly?
    Is it:
    - the „MS SQL Import and Export Data“ Tool
    - the “MS SQL Integration Services” Tool
    - not Oracle dump *.dmp format because it is a propritery binary format
    - flat file *.csv (delimited format)
    Thanks!

    Hi lingodingo,
    If you want to directly export all tables from Oracle database to SQL Server, I suggest you use SQL Server Import and Export Wizard. Because you just need to follow the wizard with GUI, this is the easiest way.
    If you want to make some modification for the tables‘ data before loading to SQL Server, I suggest you use SQL Server Integration Services package. For more details, please refer to the following similar thread:

  • What's the easiest way to cut out about 20 seconds (in the middle) of a minute+ vid that i made on and downloaded from my iPhone 6

    Hi - I'm a vid beginner, actually have a training session tomorrow at an App Store, but for now...what's the easiest way to cut out about 20 seconds (in the middle) of a minute plus vid that i made on and downloaded from my iPhone 6? I I'mported the clip to iPhoto on my new Macbook pro. The TRIM function in iPhoto seems only to want to let me cut from either end. I guess if I do cut out a section in the middle, maybe 'glueing' the sections back together is too much for iPhoto to handle (?). I spent about 10 minutes just trying to (unsuccessfully) import to iMovie, so that aint working either. Quicktime maybe? Thx for reading

    Hey jabXhook,
    Thanks for the question. You may have already received your answer from the Apple Store yesterday, but iMovie is definitely the way to go if you want to trim or split clips. Check out the following resource:
    Trim, split, and move clips - iMovie Help
    http://help.apple.com/imovie/mac/10.0.6/#/movf8b8fc9b2
    Trim unwanted frames from a clip
    1. In the timeline, select the range of frames you want to keep in the clip.
    2. Control-click the clip, and choose Trim Selection from the shortcut menu.
    The clip is trimmed to the boundaries of the selection.
    Thanks,
    Matt M.
