How to add a name to Jtree froma textfield
HiAll
I havea Jtree f_viewtree
I have a dialog box which contains a textfield and gets a name of group to be added in the Jtree and also a add button. when the add button is clicked
the name should added it to the Jtree.
I know there s method called setText(text)
String text = grouptext.getText();
f_viewTree.setText(text);
does anybody knows how this works????????
I would suggest tha you read the tutorial section on handling trees, in particular on the relationship between JTree and its TreeModel.That makes 2 of us. I already gave the OP that advice 1 week ago when the same question was asked:
http://forum.java.sun.com/thread.jspa?threadID=5299814
To the OP, quit multi-posting and wasting our time. You have not made any effort to post your SSCCE showing what you are attempting to do. We have no idea what your problem is. The code from the tutorial shows you how to do this. The code we post would not be any different.

MSRV* Reports: How to add Vendor name?
howdy gurus!
Appreciate very much for any guidelines on how to add vendor name in MSRV* reports.
Cheers,
RonThanks for the inputs guys.
So there's no technique yet to include it (similar to FBL*N and CJI3/KSB1).
No available note also in SAPNotes.
I already developed the Z* report but the key user requests the possiblities in MSRV*.

How can add a name to the dictionary
Everytime I put my daughter's name in a text msg, it suggests other spellings of her name. My crackberry let me add her name spelling to the dictionary? Does the iphone have something similar?
Names are added by rejecting the autocorrect selection. If you continue to tap the "x" when autocorrect suggests an alternative spelling it will eventually learn from this and stop trying to correct the spelling.

How to add website name to video with QTX?
I want to add the name of my website to video clips in such a way that it will be difficult for others to copy the video, remove my website name and republish it without any credit to me. At present I am using QuickTime to 'Save for Web' and then uploading the resultant file (M4V) to my website. The videos are just video blogs so they're not high-tech productions!
I am running Snow Leopard 10.6.7. I used to have Quicktime Player 7 Pro. I now seem to be running QuickTime Player 10.0
I cannot find a User Guide to QTP 10. The user guide for QTP7 does refer on page 35 to adding text to a video but a) it refers to a Clipboard I can't find and the menu options don't match what I'm looking at in QTP10; and b) if I can find a way to follow these instructions, how easy will it be for someone to simply download my video file and remove the text anyway?
I'd appreciate any help or advice you can offer.I am running Snow Leopard 10.6.7. I used to have Quicktime Player 7 Pro. I now seem to be running QuickTime Player 10.0... The user guide for QTP7 does refer on page 35 to adding text to a video but a) it refers to a Clipboard I can't find and the menu options
If you had QT 7 keyed for "Pro" use when you upgraded to OS X.6, then a Snow Leopard versions of the QT 7 Pro player should have been placed in the "Applications/Utilities" folder automatically. Alternately, if you still cannot find QT 7 on your upgraded system, you could try using the free MPEG Streamclip application. In many ways it functions as a QT 7 Pro alternative for conversions, merging files, and such but does not have QT 7 Pro's layering and masking features. However, it does have a built-in text "watermarking" feature in the "Adjustments" window. I.e., instead of using the QT X "Save for Web" option, you would use the MPEG Streamclip "Export to MPEG-4" option and add your "text" watermark before actually performing the export. Alternatively, many QT 7 Pro users add a graphic watermark or logo as a means of identifying their content. If interested, here are a couple of old QT "Quickie" tutorials for adding a graphic logo/watermark:
Adding a Graphic Logo
Adding a Graphic Watermark
how easy will it be for someone to simply download my video file and remove the text anyway?
If you embed a watermark or logo before exporting your file to its final compression format for posting to your site, then it is virtually impossible to remove totally without editing each frame of your clip at the pixel level. (It would, however, be easy to cover the logo or watermark with an opaque mask.) On the other hand, if you add the logo or watermark, text or graphic, as a post export edit in its own track layer, then it is quite easy to remove it using an application like QT 7 Pro or, in rare cases, by simply copying the main audio/video tracks to a different file container type. -

How to add file name by sqlldr
Hi All,
Can anyone kindly give me an approach to use a variable in a sql loader ctl file. I am trying to add the value before each insert of row and this value is the file name. So the question is how can I dynamically identify the input data file name, if not, is there a way I can make my SQL Loader to insert a value (file name) before each row into the table.
my control file like below ,
LOAD DATA
INTO TABLE "user"."AAA_BILL"
APPEND
REENABLE DISABLED_CONSTRAINTS
EXCEPTIONS "USER"."AAA_BILL"
FIELDS TERMINATED BY '|'
(Streamnumber ,
MSID ,
UserName,
Domain,
UserIP ,
Correlation_ID)and the loading script as below ,
for j in $(GetFileNames)
do
let i=$i+1
sqlldr user/pass control="/u01/ctrlfile/loadBILLDtl.ctl" log=$WiMAXlog$j.log data=$WiMAXsource$j bad=$WiMAXlog$j.bad
GetFileNames ()
sqlplus -s user/pass << EOF
set echo off
SET FEEDBACK OFF
SET heading off
set pagesize 50000
select bi_file_name from dbm_bill_head where bi_file_name like 'WiMAX_%' and bi_auto_status=35 order by bi_file_name;
EOF
}What I am trying to accomplish here is, I want to insert the data file name along with other data in the data file into table AAA_BILL and this table has the file name coloumn, but the data file does not contain the file name as one of its contents.
Note : my DB is 10G and OS is RHEL
any help please ,
Edited by: 876602 on 18/12/2011 05:44 صHi,
Now it is working just well.
I kept 2 variables: one with the POSIX file path for my do shell script and another one (using the provided tip here) for the Applescript function.
The only problem I had left was that teh file was writen in, maybe, UTF8 so I added to the open for access a "as text" at the end to make the file as straith text file.
I always found languages like Applescript a little bit hard to learn. Strangely, I have less difficulty with Cocoa!
Thanks for avery one here! -
How to get my Name in the From Field instead of email address?
For an Exchange Activesync account, how do you get your friendly "Name" to show in the From: field rather than email address ([email protected])?
I seem to be able to do this fro IMAP/POP accounts but not Exchange Activesync.
All the discussions I've found about gmail and Activesync seem to be centered on getting your messages to show a different return email address than your exchange account. I'm not looking for this, just to show the Name.
ThanksIf you add a contact ("Contacts app>> "+">> enter info) with that email address, it will appear in mail with whatever name you set in the email address' contact.

How to add Distribution Group email alias from CSV in office 365
Hello Forum!
Hope someone can help me troubleshoot this or even let me know if its not possible. But, I used powershell to import distribution groups and set primary emails in Office 365. That worked great, but we have two domains and i would like to add an email alias
to all my DGs for the other domain.
This was my best attempt and its not going well:
Import-CSV "C:\distributionlists.csv" | foreach {Set-DistributionGroup "$_.Name" -EmailAddresses SMTP:$_.PrimarySmtpAddress,$SecondarySmtpAddress}
$_.Name is the column name for my DGs. IE: DL-IT
$_.PrimarySmtpAddress is the column name for my primary email. IE: [email protected]
$_.SecondarySmtpAddress is the column name for my email alias. IE: [email protected]Hi,
Based on my understanding, the below code should work when your manually run it:
Set-DistributionGroup "DL-accounting"
-EmailAddresses SMTP:<Primary Email>,<Alias Email>
If all those distribution groups have been already created, then use set-distributiongroup command should work. How about first new those distribution group, and then run foreach block to do the loop.

How to prevent middle names and titles from appearing in contacts
My iPhone is syncrhonised with MS Outlook, and I've used Outlook as my system of record for contacts for many years. I have hundreds of contacts in Outlook, many of which contain middle names and titles.
The problem is that the iPhone displays every contact as Title FirstName MiddleName Surname Suffix. For many of my contacts, particularly when viewed in the Favourites list, I can't even see the contact's surname because the contact's title, first name and middle name(s) take up so much of the row.
How can I stop my iPhone from displaying titles and middle names? Is there a setting somewhere in iTunes that will prevent these fields from being transferred to the iPhone?@NFH
I am also experiencing this problem, but I think it started with one of the later iOS 3.x releases or possible iOS4. All of my contacts display their job title (eg. "Senior Vice President of Worldwide Sales & Operations") which given the screen real estate means that NONE of the actual Contact name is visible.
This is only happening on my iPhone 3GS (iOS 4.0.2) and does NOT happen on my Mac, my me.com, nor on my iPad (iOS 3.2.2). Which, again leads me to believe this problem was introduced in iOS4. -
How to add document name and document namespace to xml mail sender msg
Hi,
I have set up a sender mail CC that accepts messages already in XML format. However, the messages are missing the document name and document namespace. I am trying to use MessageTransformBean to add these to the message payload. However the examples I've found so far all talk about converting plain text coming in. When I used convertionTpe -> SimplePlain2XML it messed up the original content with unnecessary xml tags.
Can someone please tell me how to insert the document name and namespace into the payload without converting the original xml content? Thanks in advance.Dont think there is a way.
As the source is a XML, why dont you create the MessageType with the same name and namespace as the XML file in the email.

Bhavesh
