Need Help In Moving An Item

Hi Guys,
I am trying to move an item in a list upward but it is not working the way i want. The element that i select still remains after it has swapped position with the previous elements. I am using Jlist .
listTasks is a JLIst
and
listModel is ListModel
For instance if i have
1
2as a list, after i select 2 and click the up button i get
2
1
2This is the code snippet :
public void mouseClicked(MouseEvent e) {
          int id = 0;
          if(e.getSource() == this.lblUpArrow){
               id = this.listTasks.getSelectedIndex();
               if((id > 0 ) && (this.listModel.size() != 0)){
                    Object value = this.listModel.getElementAt(id);
                    Object previousValue = this.listModel.getElementAt(id - 1);
                    this.listModel.insertElementAt(value.toString(), (id - 1));
                    this.listTasks.remove(id);
                    this.listModel.insertElementAt(previousValue.toString(), (id));
                    this.listModel.remove(id + 1);
     }thanks for your help.

Needing help with moving pictures around

I am in need of help in moving pictures and images around
dreamweaver document window. My older brother gave me his computer
witch has dreamweaver MX (he is in Irag) so i can start building
building my own websites. I went to borders and bought a book on
dreamweaver MX. Here is where I am having a problem with: when ever
I bring a picture into the document window I can not move the
picture around the document window. The book say "place the
insertion point where you want the image to appear" but there is no
insertion point. There is just a straight line as if I am about to
type something. It's almost like I am in microsoft word. If I take
the mouse over the picture , and then left click and try to drag
the picture to the location I want it in, it doesn't move. Can
somebody PLEASE help me out with this problem. Thanks Jical

Nadia gave you a good place to start… Here is what you
have to understand. Web pages are based on specific code that tells
the viewer’s browser how to display the page. There has to be
something that says, “Put this picture in the lower right
hand corner, and center this image in the middle of the
screen”
Then there are further instructions that say “Put this
text here and that link there”. So Dreamweaver (and most
other web developing programs) do not work like Illustrator or
PowerPoint where you can simply grab a picture and slide it around
the page.
In its simplest form you might drag an image onto the
Dreamweaver design view page and click on the center button in the
properties dialog.
Then type in text and center it, left justify, right justify,
etc. Add another picture and so on and you could possibly create a
passable web page. Now click on the Code view button and see what
code Dreamweaver generated in order to do all of this.
That is what you will really need to understand before you
can really get proficient at web design.
At the next level, you can start to add in tables. These
actually are similar to tables in Word. You can put text in one
cell, images in another, colored backgrounds, thick and thin
borders with contrasting colors, and you can start to see how to
“contain” your images as Nadia suggests.
Now look at the code again and see how these cells are
defined around your content.
Once you understand how this works, you will get much more
comfortable with Dreamweaver. You will just have to get used to the
idea that it doesn’t work like all of the publishing software
that is only dependant upon its own format for layout. HTML is
dependant upon the many browsers, computers, operating systems,
user preferences, and a million other unknown factors.
That’s why this forum has more than 91,000 posts…

Need help with moving items betwen 2 netui select boxes

Hi,
I have 2 multiple select boxes for possible courses and assigned courses. I need a way to implement move of option items from one box to another using buttons. The user can select courses from one box and move them to another. I am not sure how I would do that with netui select boxes and a pageflow method. If I use javascript, i get all kinds of errors even though I am trying to use the tagid. If validation fails, then the select boxes dont save the updated content.
Please help.

I need help with moving my iTunes library to a new disk...

I'm soon gonna get a new SSD which is half the size of my HDD. So i guess i wont be able to restore with time machine or use disk utility to clone the drive. I'll have to start with a fresh copy of moutain lion.
What I'll want to do is that keep all my music on my ssd and let all the podcast and itunes u be on an external hdd.
can someone outline the steps to...
create a library on the ssd on which os x is installed.
move music, playlists and apps.
let the podcast and itunes u be on an external hdd and yet be accessible from itunes, like being referenced.
in the past i did this by moving the entire library to the internal drive and then while itunes was running, move the videos from the library folder to the external drive. it autoMAGICALLY was able to find the videos on the external drive while my music and apps were stored in the internal.
now my library size is so big with all the videos that i cannot do the above steps as i want be able to copy the entire library to the internal ssd.
any help is appreciated.
thanks in addvace.

Sometimes we sleep. We have even been known to be away from the keybord to bathe (but usually not for longer than 2 minutes once a week ).
I don't know how you automagically did it last time - your details are lacking. iTunes is normally terrible at following you moving things, especially from drive to drive. You either have to let iTunes do the moving (by consolidating to a new location) or you have to disable iTunes managing your media in which case it will follow moving inside a drive but still not between drives.
Despite the new version, iTunes still does not make it easy to split your library between drives. Probably since you only buy your items from iTunes and are never away from a high speed Internet connection it doesn't matter since you can always stream or download items you need from your Match subscription, right?

Need help finding moved image files

How would I find files after they have been moved? I travel and use a MB Pro laptop. The workflow I'm using is to download images to my desktop, review, rate and add keywords immediately. I make 2 backups, 1 to portable data store hard drive and one to DVD. Then every few days I erase the desktop image files. When I arrive home I download the entire trip's images from the portable storage to my desktop drives (2 500Gb SATA drives).
Is there an easy way to direct Aperture to look for the files in the new location? Or, failing that, is there a better way to work? I regularly have 40 - 60 Gb of images after a trip and the laptop hard drive is inadequate for the task.

The question isn't really clear to me yet. If you know what "the new location" is, then it's easy to make Aperture point to it. But that may not be the question. I think you may need to describe your workflow in more detail.
You don't say how to review etc images on the MBP. If you're using Aperture, it must be with a library. Are you using Managed images there? So is the problem how to transfer data -- images and edits and metadata -- from the library on the MBP to the library (with referenced images??) on the desktop?
Synchronizing libraries is not something Apple makes easy or offers any real help with. The best way to do it turns out to be to export one project at a time, connect to the other machine and its library, and import the projects. (In the process you might also Relocate images to make them referenced.)
But your note about the laptop drive being to small is confusing. I don't see where your images are when you're on the road.

Hi
This is possible, please follow as below:
If it is GL (FBL3N), Customer (FBL5N), Vendor (FBL1N) line item use the TCODE' mentioned.
In the selection screen, if possible give all the document numbers (it is possible with addition selection).
Once you get the output with the line item, select all line items and go to the menu options there you can see the mass change option, it will give one popup screen give the new value in the text field and proceed further.

Need help with moving sight over to Iweb

I would like to start using IWeb but I already have a website built that I used Frontpage to create. I want to make some changes to the sight so if I cannot convert some of the things I have, Im ok with adapting!
www.DarnGoodSeasoning.com
1st question: (Visit site above) if you hover over the links on the left they turn green Can I do that in Iweb? I figured out how to do it with font but not pictures. I have the .gif of each in yellow and green.
2nd When I have created pages in the past www.HeyRobi.com It changes the name in the address bar to http://heyrobi.com/Mac/HeyRobi.html Call me petty but I want it to say HeyRobi.com can I fix that?
Thanks in advance for any help or tips. If there is any advice or tips how to improve the Darn Good site I am always up for constructive criticism. BTW I am dropping the frames!
TIA HeyRobi

Welcome to the Apple Discussions. 1 - The rollover options are only available for text, not images.
2 - To get must HeyRobbi.com to show in the URL window you'll need to use standard domain name forwarding with masking. Then every page of your site will display only that. The downside to that is visitors will be able to only bookmark the first or entry page of your site. That may or may not be a problem for you. My tutorial site, toadstutorials.info, is setup with masking.
The following is a screenshot of how I setup my site with GoDaddy.com for forwarding and masking. Although every domain name provider is different your's will have a similar setup for you to set the masking for your domain name.

Need Help in Moving from ABAP to NW Portal Development

Hello Experts,
I am ABAP Programmer. I am not having JAVA background and intrested in Portal Development. I had found following courses:
JA100, JA300, JA310, SAPEP, TEP12.
Please let me know whether these shortlisted courses are correct or not. If not, please give me correct sequence of courses.
Thanks in Advance.
Regards,
Nilesh Pawar.

Hi Nilesh,
you better can give a try to XI (Exchange Infrastucture) which also is an important part of Netweaver Platform.
If you are so keen to pursue EP, then you should have a minimum knowledge on Java, Core java, JSPs, API etc.
And you can manage with webDyn pro applications where the need for coding is only 10%.
But most of the ABAP developers find it easy to move to XI rather than EP.
Hope this was helpful for you.
Do offer points if you like.
All the best and you made a good decision .
Future seems good with Netweaver.

Need help with moving files?

I now have two challenges. As a new user I need to know how to copy my iTunes files onto a USB stick. I am not sure how to find the files, copy them or anything, the second thing that I need to know is how to remove files from the desktop. While trying to copy these same music files I clicked at the wrong time and now they are all piled up on the desk top. There are 1800 files all piled up. Just want these gone. Thanks for any help.

While trying to copy these same music files I clicked at the wrong time and now they are all piled up on the desk top. There are 1800 files all piled up. Just want these gone.
Click Finder and desktop. Assuming for simplicity that there are only the 1800 files on the desktop that you want to delete them (important that you have saved them somewhere else where you want them) .... click on the first one in the list to highlight it, then move to the last one in the list, hold the shift key and click on it to highlight it. All in between should also now be highlighted. Either drag that group to the trash or right click and choose move to trash. Then empty the trash.
If you want to copy the files on the desktop to the USB stick, follow Niel's instructions above.
On your hard drive, you'll find your itunes library under your user ID / music / itunes

Need help with moving files into Itunes and syncing

Please help.
I have an external hard drive with my music on it. I created a new playlist in Itunes and did a drag and drop from my external hard drive into my newly created playlist.
Now that I go back and play the items I brought over, I get an error that says "original files not found" and it won't play and therefore does not seem to be syncing to the Ipod to be able to play.
Can you please give me guidance as to what I can do without recreating all the work I had already done?
Thanks,

Is the external drive connected?
Has the drive letter possibly changed due to being disconnected and reconnected?

Intel Core 2 Duo's are the most efficent, so if you are looking for good battery life, that is what you want. Avoid AMD as they eat the battery life quite quickly.
The battery life depends on what the computer is doing, so if you are stressing it with a lot of applications, yes the battery is going to die quicker than normal.
My opinions are mine, and mine alone.

Need help on moving itunes to different computer.

i am getting a new computer.
But my old computer has my itunes and doesn't read disks.
how do i transfer the itunes to the new computer without being able to use the disk drive?
please help.

Probably the most straightforward way to get iTunes onto your new computer is to network it with the old one and copy your iTunes folder across. This works fine if you have been using iTunes to completely manage your music and all your songs are in iTunes Music not in different folders. You can also use this method with an external hard drive, you drag the folder from the old computer to the external drive and then from the drive to the new computer. If the songs in your library are not all in the iTunes Music folder you can consolidate them. When you consolidate, any songs in the iTunes Library that are not in the iTunes Music Folder are copied to the Music Folder and the Library is updated to point to those new files. Files already in the iTunes Music Folder have no changes made to them: Copying all your iTunes files to one location - Windows
Copying the whole folder brings with it the iTunes Music folder and also the iTunes Library (iTunes Library.itl in Windows) database file which holds all the information about your songs (Playlists, Ratings, Play Counts, Last Played, Date Added, etc). You'll get more information including the Folder/File structure in this article: What are the iTunes library files?
When you copy the iTunes folder make sure you put it into the same location on the new computer. This has to be the exact same place, on a PC this is \Documents and Settings\Username\My Documents\My Music\. When you open iTunes on the new computer it will be the same as on the original one Songs, Playlists, Play Counts, Ratings etc. When I moved iTunes a while ago for my daughter I was also using the same version of iTunes, not sure how important that is but it's probably worth keeping them the same.
If you have an iPod it can be used as an external drive and you can move the iTunes folder onto it: How to use your iPod to move your music to a new computer

2) ignore the other header guid and object id because it is for whole contract
3) if u had custmize any table it will be available in the internal table returned by the function module.
4) u have to identify which internal table will contain the field since many internal table are available with similar meaning.
4) CRM_ORDER_ORDER is heavy function module it reads entire contract hence u need to specify which internal table u have to read any only those values will be read. for that u have to fill in <b>it_requested_objects</b>
