Help needed in linked lists...

I have been working on this computer assignment lately but I still don't understand linked lists yet..I did an assignment on array based implementation and now I am supposed to do the same thing in linked list implementation..
I need help on how to change this into a linked list implementation..any help would be appreciated. Thank you..below is the code for the array based implementation..the only thing that needs change here is after where is says Array-based implementation of the ADT list.
public class ListArrayBasedDriver {
public static void main(String [] args) {
    ListArrayBased myGroceryList = new ListArrayBased();

Help needed with xml list

hi,
i need to make a list in which all the list items will come
from xml file. these items will also be clickable so that they open
a new respective hyperlink on click. i need something like
www.sponky.com ' s portfolio list. can somebody please help me? i
really need your help.
thanks,
gaurav

I'm hoping I understand what you're doing... I would probably
do it all in one frame and just toggle the .visible property of the
subcategory list after the first one has been clicked, but there's
no rules about how you do it.
Without being sure, I think what you may have done is put a
second "copy" of the category list on another keyframe, which
replaces the previous instance. By taking away the second copy it
should work. If that's not the case, then I'm stumped... otherwise
read on.
So if you have the category list in its own layer, just have
it in frame one, on frame 2 of the same layer have a frame but
not a keyframe. This will mean the instance in frame one is
still the same one when the playhead gets to frame 2.
And have the subCategory list on a separate layer, it appears
on frame 2...
BTW the .getSelectedItem() method of the list reminds me of
flash mx... is that the version you're using (curiosity only I
don't think its relevant, because its obviously working).

Dynamic Population of List Item Not Working

My requirement is to have 1 list item that is populated based on the value selected for a second list item. in the when-list-changed trigger of the second list item, i make a call to a procedure (code below). This seems to not like any of the clear_list or populate_list. the list item type is poplist. i set the class to list. if i use populate_list in when-new-form-instance, there's no problem. PLEASE HELP. When can't I populate list using a procedure??

                         message('tooto');
END;

Thanks for the response. I've tried this example too and it still doesn't like the things mentioned in previous post. In addition, it doesn't like SET_RECORD_PROPERTY(:system.cursor_record,'EMP',status,new_status); I get the same sort of error. The form compiles fine though.
Background on form:
this form was created to allow users to dynamically build an update statement. On this form are a number of list items and text boxes that are not populated from a database. So the datablock doesn't retrieve values from the database and the only updating that will be done is when the user clicks an "update" button to execute the sql statement that is built. Could this issue I'm having be related to the way i designed my datablock and items? When the user selects an item from one of the list items, the record status goes to "Changed". So I assumed my issue was because of this and thought the set_record_property statement would help...but that is generating the same error. what am i missing? if i look at the index value of the record group after create_group_from_query, it is -1. after populate_group, it is still -1. should it still be -1?? any help is greatly appreciated.

Help needed to setup template item list to send attachement within email te

Hi! I read everything there was in the bookshelf on the setting of template on Outbound communication, advanced template and my main concern, template items list and I still can not send a template email with an attachment inside. I managed to send the email with the attachment in the message body but not send mail with an attachment separately.
Is there a special feature or setting to the template items list or in the Siebel file system that needs to be done ? I've try to put a tag pointing to the template item in the advanced template but got no result. I've tried everything but got no result.
My main goal is to send a template email containing the attachement of an official letter inside. Ideally, I would like the letter as an attachment to be populated by the data of the BC associated (values substitution). This is already working in the advance template. But that's another story. I would be happy if only I can send the email template to include the letter as attachement.
Thanks in advance for helping me!

Yes we do. Even if we go with F9 or by the send email from the file menu, the sending of emails is ok. It's just that it wont send attchment as define in the template item list. All settings are ok and are as specified in related bookshelf. By now, i'm looking if there is any activex control missing for outbond email OR if there is any html tags to put inside the advanced template so that the application could properly attach the file to the email. If you have aswer on you side, it would be appreciated.
Jean.

Help needed in removing duplicate items of list box in java

How to remove duplicate items of list box while dynamically inserting (on-click event)
It is not identifying duplicate data
Variable name is HP_G1
HP_dmg1 = (DefaultListModel) HP_G1.getModel();
int a = HP_G1.getModel().getSize();
System.out.println("HP list no--------> "+a);
if(a!=0)
for (int j=0; j<a; j++)
String item1 = String.valueOf(HP_List.getModel().getElementAt(j));
System.out.println("HP list added--------> "+item1);
if(HP_dmg1.equals(item1)){
HP_dmg1.remove(j);
else
HP_dmg1.addElement(GPL);
}

Your code is unreadable, so I'll ignore it. In the future please press the message editor's CODE button to format code.
As to your problem, to the point you normally use a Set instead of List when you don't want duplicates in a collection.

[JS][CC] Help needed with targeting pasted item

Hi.
Is it possible to be able to targer a selected chunk of text, copy it, and paste it into the page and then identify the pasted frame?
I can do everything up to the identification of the item.
I have used
myDoc.pages[0].allPageItems[0]
and this sems to work the first time, but I need to repeat the task multiple times, and all subsequest times, I am not targeting the pasted item, rather another text frame that already existed on the page.
If the worst comes to the worst, I can get all the text formatting attributes, and re-apply the text in a new frame and apply the formatting attributes, but this is not ideal.
I am sure I am doing this the wrong way, so any help would be great!
Cheers
Roy

@Roy – Does the following snippet work for you (tested in InDesign CS5.5)?
Selection must be a text selection:
app.copy(app.selection[0]);
app.select(null);
app.paste();
var myNewTextFrame = app.documents[0].windows[0].activePage.textFrames[0];
myNewTextFrame.fillColor = "Yellow";
Of course, you could run into trouble, if the selection exceeds the current spread…

Help needed! GMail sent items missing from Apple Mail!

I need your help to solve a problem that I've identified recently in Apple Mail with a GMail account:
I have a POP-enabled GMail account in Mail, but also with IMAP functionality enabled through GMail's webmail settings (probably because I access it also from my iPad).
However, I notice that my local "Sent" mailbox in Mail only contains some 140 messages, even if a visit to GMail's webmail page shows me that I have at least 1200 "sent" messages.
I must note that my advanced mailbox settings in Mail do NOT allow for automatic deletion of sent items.
So my question is: how to make sure that I do not lose ANY sent items from GMail or any other account for that matter (i.e., that whatever is sent remains in the local "sent" mailbox in Mail)? Am I missing something?
Thanks a lot in advance for your help.

Or am I saying something stupid?
No I don't think so. But from what you're saying, the only copies of sent messages on your computer will be what you are sending from the computer. The messages sent from the iPad or website are not stored on the computer. If it were all set as IMAP, they will be available on all devices.
Thanks a lot for your attentive reply - my only concern is that, when I activate IMAP, I won't be able anymore to have a steady copy of all items in my sent items folder on Apple Mail, nor to delete what I want at will.
Changing it to IMAP will make the all sent items available on the server to your computer, website, and other devices. They will always be there as long as you don't delete them from the server. The messages you manually delete will delete them from the server and all devices. If you want a local backup, then copy them to a local folder which will not remove them from the server or move them to a local folder which will delete them from the server.
Auto syncing does not in any way interfere with local folders on the Mac. The only IMAP folders you can sync are the inbox, sent, drafts, and junk. Inbox is the only mailbox that has to be synced (it's done automatically and you can't change it). I also sync the Sent and Trash. I don't sync (store messages on the server) the drafts or junk mailbox.
I don't understand what you mean by not being able to delete messages from the Inbox. I do it all the time. What happens when you delete it depends on your settings in gmail. Gmail has some peculiar settings like having a deleted items folder besides the Trash folder. The default is to delete from inbox, it goes to the deleted items folder. Delete it from there, and it goes to Trash. Delete it from trash to get rid of it. The fact is that the All Mail folder shows the message no matter what folder it in. I have mine set to move it straight to the trash when moved from the last visible IMAP folder. So, when I delete it from Mail's Inbox, it moves it to the trash just as local messages do.
If you plan to do your email from the computer only, then POP is fine. If you plan to use the website and iPad also, then IMAP is the way to go.
That way everything in mail is available no matter where you look at it. The only things you won't see is what you move to local folders.
Seems like you should go to gmail's website and read the help files to become more familiar with it. Also look at all the settings available (expecially the Labels Tab, Accounts tab, and Forwarding Tab. These settings will be what you will use mostly to customize how it works and flows with the Mac. If you're going to use IMAP, you need to understand what they do exactly and what you want them to do for you.
My sole objective: to keep ALL messages in Apple Mail (except those I expressly delete), as well as ALL messages in Google.
IMAP does exactly this for you already. By leaving it on the server, they are on the computer. In Mails preference settings in the Accounts / Advanced Tab, for IMAP accounts keep the setting for storing messages for offline viewing. That way Mail actually does store a copy locally until you delete it from the server. And that will be backed up with your computer backup.
And what you do delete from any device will duplicate it elsewhere.

Help needed in Print List Archiving

Hi Experts,
I have archiuved the Print or Spool List and I am able to see that in the OADR Transaction.
While tring to open document from storage I am getting this error : <b>"Error calling application via OLE ALVIEWER.APP"</b>.
What is the cause of this error. Please help in rectifying it.
Regards,
Arul Jothi. A.

Hi Arul,
The message shows that the IXOS Viewer was not being installed in your machine.
You may request the IXOS Viewer installer from OpenText directly. Or another workaround is to change the printlist display using SAPGUI from TA OAA3. But is might not be a good idea as SAPGUI only allowed to display upto certain number of pages only.

Help, need to get deleted items back.

I have items purchased through the iTunes store that were accidentally deleted, how do I get them back? They were fully downloaded so I can't "Check for Purchases", they just got deleted and they shouldn't have. Some of them were deleted by someone who didn't know what they were doing, and some were deleted by children smashing the keyboard and hitting the delete button. They aren't in the trash bin and I can't find any way to get them back! Do I have to buy them again?

Since you purchased it off iTunes then use the iPod + iTunes "transfer purchases" feature. Plug your iPod in and iTunes (it has to be iTunes 7.0 or higher) and iTunes should ask you immediately. Or you can option click on the iPod in the source list and click on transfer purchases. Of course, I'm assuming that you have an iPod. And for preventing future accidents like this I recommend activating "require password to wake this computer from sleep or screen saver." This option is in System Preferences>Security. Of course you'll also have to activate screen saver or automatic sleep after x amount of minutes.

List item in multiblock

Hi,
I've a multiblock with 3 columns, office_no, office_name, user_name. I populate office_no and office_name by using refcursor. After populating the first 2 columns i need to populate the 3rd column (user_name) which is the list item and its not database column. In other words the list item needs to display all the "user_name" in each "office_no"
I tried post-query trigger of the multiblock but no luck. I don't see errors but its not populating the list items
DECLARE
l_rgrpid RECORDGROUP;
l_status NUMBER;
list_id ITEM;
BEGIN
l_rgrpid := find_group('rgrp_m_id');
IF NOT Id_Null(l_rgrpid) THEN
delete_group(l_rgrpid);
END IF;
l_rgrpid := create_group_from_query('rgrp_m_id','SELECT user_name FROM user_office where office_no = ' ||:block1.office_no);
list_id := find_item('block1.user_name');
clear_List(list_id);
l_status := populate_group(l_rgrpid);
populate_list(list_id,l_status);
END;
please advise or any other way to do this? i'll appreciate your help. Thank you.

It looks like you want one list item to containt different elements for each record of a block. This is not possible in forms. The best you can hope for is to have a single list item on the form, in a control block, and populate it (and set its value) in the when-new-record-instance trigger of the data block, making sure you set the value of the appropriate field in the data block when the list is changed.
An LOV would be the best solution in a forms environment so if the requirement asks for something different you should find out why. Given a choice between 2 options which are technically possible, the LOV might be the preferred option.

Re: Empty record in list item

I would be very greatful it anybody could help me.
I have created a recordgroup for list item and populated the same. All values are dispalyed properly but in addion one empty record is appear. how can i remove the empty record ? my syntax are as under:
declare
v_rg NUMBER;
v_GrpID RECORDGROUP;
begin
v_GrpID := CREATE_GROUP_FROM_QUERY('DRVCODE', 'SELECT led_name ,led_name FROM master_ledger where cmp_code=:global.cmp_code ORDER BY 1');
v_rg := POPULATE_GROUP(v_GrpID);
IF v_rg = 0 THEN
POPULATE_LIST('master_driver.tdrvname', v_GrpID);
END IF;

Just add the last line after your code... that is you set the value after populating the list-item;
declare
v_rg NUMBER;
v_GrpID RECORDGROUP;
begin
v_GrpID := CREATE_GROUP_FROM_QUERY('DRVCODE', 'SELECT led_name ,led_name FROM master_ledger where cmp_code=:global.cmp_code ORDER BY 1');
v_rg := POPULATE_GROUP(v_GrpID);
IF v_rg = 0 THEN
POPULATE_LIST('master_driver.tdrvname', v_GrpID);
END IF;
:master_driver.tdrvname:= v_value;where v_default_value is a variable containing the default value for your list_item (or the specific value that you want it to be pre-set, that could be a table stored value).

Editable list item

Can a list item be editable...I have populated a list item using a record group.The user should be able to edit the values in the database using this list item.It is a poplist.

you want to edit the data which is shown in the list item?
if you select the data from a table to show it in the list-item, then you have to update the data in this table. Create a form, which you use for this lookup-table and update the data through this form...

okk..well still i don't know the purpose of the form on which you are working why not the database block for emp?..but the requirement you are asking can be done through following code...
Trigger - WHEN-LIST-CHANGED
DECLARE
CURSOR F_Cur IS
    SELECT ename
    FROM emp
    WHERE deptno = :list_item_name;
BEGIN
GO_BLOCK('BLOCK3');
FIRST_RECORD;
CLEAR_BLOCK;
FOR G_CUR IN F_CUR LOOP
    :block3.item_name:=G_CUR.ename;
    NEXT_RECORD;
END LOOP;
FIRST_RECORD;
END;
Note: in the BLOCK3 there should be one item navigable by cursor. I mean if block3 is having only one item which is name item and it is display item then GO_BLOCK built-in will not work. So, you will need to create one more in block3 or make that name item as text item and set update_allowed to NO from the items' property.
