Remove the default elements of a listbox

I want to simply delete the default elements from a Jlist box. I have read some literature about doing this, but it seems so complicated. I want to populate the list box with my own values. Is there some 'removeAll' function? Also, Netbeans generated code of
+lstCollections.setModel(new javax.swing.AbstractListModel() {+
+String[] strings = { "Item 1", "Item 2", "Item 3", "Item 4", "Item 5" };+
+public int getSize() { return strings.length; }+
+public Object getElementAt(int i) { return strings[i]; }+
is uneditable. How can you edit these default settings?

you shouldn't be adding elements directly to the list. You should create a DefaultListModel to manage the JList data. And yes, DefaultListModel has a clear() method.

Can we remove the default status field from OIM

hi,
even when my i am not mapping any field to the OIM status field , it is taking Active as default value. i dont require that field so is it possible to remove the default status field of OIM.
i am using database GTC connector for trusted recon.

User will always have a certain status like Active, Disabled etc, so even when you doesn't map it to any attribute the OIM solution calculates it with the help of the user's Start Date, End Date etc.
A user is bound to have a status.
Thanks

Want to remove the default value of a column in a table

HI
I have a table called User_ind. This table columns have default values as 'n' like
create table user_ind(
ind_num varchar2(1)
,group_allowed varchar2(1) default 'y'
,view_allowed varchar2(1) default 'y'
now i want to remove the default values How can i procede with this.
Urgent .
Thanks in advance.
Chaitanya.

In Oracle 9i you cannot remove the DEFAULT, you can only change it to null:
alter table user_ind modify group_allowed varchar2(1) default null
You can check it using this one:
select table_name,column_name,data_default
from user_tab_columns
where table_name = 'USER_IND'

How to remove the default members of a dimension from the control table?

Hi all,
I am new to hyperion FDM 11.1.1.2.0.0 .
When I navigate to Metadata>Control Tables and try to delete the default memmbers
for the dimension like category and period i got the following error.
Error: Period( 8/31/2009 ) is an active Global or Local Period and cannot be deleted.
Then again i unchecked active checkbox for that dimension from Hyperion Essbase Integration Setup of Workbench Client.
After doing that i got the following error
Error: Unable to retrieve target System Data.
Can anyone tell me how to remove the default members of a dimension from the control table?
Thanks

Create a new record for the table.
Go change the POV to the new record.
Return to the control table and delete the default record.

Removing the default (View As Icon) for the control and Indicator

If you remove the default selection View As Icon for all the control and indicator, it is good for the programmer for easy to visualize the Block diagram code.

This has already been suggested - http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Default-Option-Do-NOT-Place-Front-Panel-Terminal-as-Icon/idi-p/926871
Also, note that you can already change it on your computer as mentioned there.

How to remove the default Title in Message box?

Hi all,
In the message box, there will be a default prefixed title(' Warning: JavaScript Window - ') displayed for all types of messages(Information, Question, Warning and Error). The window title that we specify in the parameter displays after this warning text.
It may mislead the user, on the type of message being shown.
I came to know that only way to eliminate the warning is to certify a PDF, and this requires signing the PDF with digital certificate and then have the recipient verify the certificate.
Reference : [Adobe Forum|http://www.acrobatusers.com/forums/aucbb/viewtopic.php?id=710]
Is there any other way to remove the default Warning message shown on the message box ?
Thanks,

Hi,
As Rick suggested dont instantiate the business object.
If you want any data's from the business object then create a same container in the Task and directly bind the container's
with the Business object.
For example if you are using the BUS2012 and you need the purchase order number in the decision step,
then create a new container for PO number in the Task.
Then directly bind the BUS2012.PurchaseOrder ---> PO number[Task container].
Thanks,
Vijay.

How can I remove the default right click option of the text Area control?

How can I remove the default right click option of the text Area control?
Is there any way to disable this control in any of the text controls available?

The iPhone does not store email addresses for received mail. The iPhone stores all email addressees for sent mail in a list of previous recipients. The list of previous recipients is not synced with Outlook or any address book, but the list of previous recipients is included with the iPhone's backup which is updated by iTunes as the first step during the iTunes sync process. The auto-addrss feature pulls from your contacts on the iPhone and from the list of previous recipients.
Different from the Mail.app on a Mac, there is no access to the list of previous recipients on the iPhone to remove a previous recipient from the list, or to add a previous recipient to contacts that is not already entered - not at the present time anyway.
The only way to purge the existing list at the present time is by restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup.
Hopefully access to the list of previous recipients will be included with the iOS 5 update.

How to remove the default value of "Inventory No." in Equipment Master

Hi Experts,
Need your advise
How to remove the default value for the field "Inventory No" in Equipment Master? It will goes back to the default value(TRANSIT) when i delete or change the value.

i think you cannot default this value from configuration, check is there any screen variant exist for your transactions IE01/IE02, else may be any user exit is active on the equipment master transactions.
Take help of your ABAPer and verify the above.

If I create an security scope for a group of SCCM-admins should i remove the "Default Scope"?

Hi,
If I create an security scope for a group of SCCM-admins should i remove the "Default Scope”?
/PS
/SaiTech

Yes, it's OK to not add the Default security scope to an administrative user. You can add any custom security scope to an administrative user and it does
not has to include the Default
security scope.
Just keep in mind that you keep at least an administrative user that contains the
All and/or the Default security scope to not lock yourself out of the console.

By how it is generated and how to customize the pdf?
Can anyone help me.

It doesn't work for me neither.
Tried many ways.
I followed the full instructions putting the jar in eclipse/plugins folder, restart eclipse.
Right click on the project, chose crystal report -> update keycode.
I edited the CRConfig.xml adding keycode tag with the value I copied from the jar.
None of above works.
Is there other ways to remove that line of message from the report?
thank you in advance.

Am I able to remove the default style borders for spryaccordian?

Am I able to remove the default style borders?
The Dreamweaver css sheet says:
This is the selector for the main Accordion container. For our default style,
* we draw borders on the left, right, and bottom. The top border of the
Accordion
* will be rendered by the first AccordionPanelTab which never moves.
I do not want the gray borders all the way around. I know how to style and remove the '.Accordian' borders
but would like remove all 'default' borders.
Thankyou

Thanks Beth, but it doesn't seem to work.
I added what you suggested to the top line. Here is what my css says with your addition:
So I have zeroed out the inner border (orange), but would like the outer gray border gone as well:
This is the selector for the main Accordion container. For our default style,
* we draw borders on the left, right, and bottom. The top border of the Accordion
* will be rendered by the first AccordionPanelTab which never moves. (gray border)
* If you want to constrain the width of the Accordion widget, set a width on
* the Accordion container. By default, our accordion expands horizontally to fill
* up available space.
* The name of the class ("Accordion") used in this selector is not necessary
* to make the widget function. You can use any class name you want to style the
* Accordion container.
#Accordion1 *, #Accordion1 {
> border: 0;
>}
.Accordion {
border-left: solid 0px orange;
border-right: solid 0px orange;
border-bottom: solid 0px orange;
overflow: auto;
Thanks for your input
