JList problems, can't write to a list

Hi there....can anyone help???
I'm having a problem with a dialog box...I use a dialog box to logon a new user (client) to my server, but the GUI on the client's side isn't showing who's online so to speak(I'm using a JList as my 'buddy' list type of window)....How do I get the dialog box to send the user's name to my client's GUI and add it to my who's online box??? Conversely how do I get the name to be removed when the user disconnects from the server??? Thanks everyone for any help you can provide....

You need to refresh the JList every time the data changes:
JList myjlist = new JList();
Vector data = new Vector(); //or use an array of type Object
//data changes
myjlist.setListData(data);

SQ01 DIsplay Problem (Can v write abap code ) Sql Query

Hi
Need help in SQL Query
I generated one sql query which has the following output in general .
Customer   name   description   amount
asrq1 sharekhan      Amount payed      10
asrq1 sharekhan     Amount Advance     20
asrq1 sharekhan    Amount due             30
but i need the output in the following way
Customer name AMount payed     Amount Advance                  Amount Due
asrq1   sharekhan 10    20     30
and iam new this sql query but came to know we can write code ..but iam unable to initiliaze to write
a peace of code as i dont know what are the select-options defined ..i saw in the include but didnt got it
% comes prefix of select-options,and iam unable to get he internal table which is displayed in the query .
can anyone help me in this answers will be awarded points.

First, I will suggest to go for ABAP report for this kinda requirement.
If you really want to go for it through SQ01, even then you will have to write some ABAP to display the records in one row. You will need to create three custom fields.
I will give Psudo for one field:
Field Name := ZAmountPayed
Select Amount_Payed into varAmountPayed from Table Where Emp# = '12345'
ZAmountPayed := varAmountPayed
Convert the above into relative ABAP code and create 2 more similar fields, and you should be all set.
You have to know the table names and any other calculations to get the right data.

If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else.
There are several ways to back up a Mac that isn't fully working. You need an external hard drive to hold the backup data.
1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

List v = new Vector() how can i write this ?

List v = new Vector() how can i write this ?
vector does not 'extends' List rather it 'implements' only ......so how can write this way ? ( polymorphism applies only for 'extends' ).

my question in a simple way is :
List some_list extends Vector
No, List is an interface; Vector is a concrete class. Read the javadocs.
Vector implements List
>
AND
List some_list implements Vector
are these two same in behaviour
our apart from theoretical differences ?thanks
Interfaces don't have any implementation; they're pure method signatures. When a concrete class implements an interface, it makes a promise that says "I will provide implementations for exactly these methods. Any client can call a method from the interface and I will do something 'sensible' if I'm written correctly."
From the point of view of static and dynamic types, there's no difference between interfaces and classes.
C++ has interfaces, too - they're classes with all pure virtual methods. If you understand how C++ works, the concept shouldn't be hard.
ArrayList is preferred precisely because it isn't synchronized by default. (You can always make it so using java.util.Collections if you wish later on.) If you don't need synchronization, why pay the performance penalty?

I installed iOS 5.0.1 on my Iphone 3GS. I never can not write in my calendar. Anyone else having this problem after their upgrade?

I was going to suggest - Settings>General>Reset>Reset all settings, but if you are restoring to factory settings, that should restore the settings back to factory defaults. But if you are restoring from a backup, after restoring to factory settings, try resetting all of the settings and see if that fixes it.
It might be something in your backup.

"Files can not write or be written to disk" (pic problem)

I can't seem to figure out why I get the error that I can't write to the disk. Does that mean I can't write to the ipod? I've tried 5 r's and still can't figure it out. Is is an OS issue on my comp? Anyway, I can't figure it out...thanks for your time.

Wrt610n problem, can't seem to write to hard drive

so i set up the router and have set up all the shares along with the user properties with admin status. I have mapped the network drive on Vista and am able to see the hard drive and play everything off it. But i cant seem to write to it, everytime i try to it says i need permission. i know i have connected via admin status with my user name not the admin user name since i cant seem to with vista.
suggestions? TIA

Hello there!
With your concern, are you connecting a USB thumb drive or HDD to the router? What's the difference?
With USB Thumb Drive attached to your router, it only reads it as NTFS and you have Read-Only permission to this. That means, only opening files. With HDD or hard disk drive, make sure it is formatted to Fat/Fat32 for read-write permission. Also, make sure the user you created on the router's storage settings is set to read-write permission as well. Take note that before you proceed with reformatting your hard drive, you have to create a backup first.
So far, this are the options you have to check. Also, test if you can read-write once the hard drive is connected directly to the computer.
Keep posted!
for heads up! <<<call_me_jam_>>>

I can't write to my Drobo

I have a new iMac (like this):
I am trying to connect the Drobo that I used to use with my Windows Computer. It has 4 drives @ 3TB each, and the whole drive is over half full, so I am not terribly interested in the cost that it would take to "back up" that whole disk pack. It took some shenanigans (reboots of both the drive and the computer; disconnections, and reconnections; fiddling around with MAC Disk Utility) to get it to show up in Finder at all. I still have issues with it unmounting and needing to remount it, but that's not my main issue.
THE REAL PROBLEM:
Though I can get the Drobo to show up in finder, and I can read from it, I can't write to it. Based on some earlier searching I tried this terminal command, which helped it to show up in finder, but didn't seem to affect it's being read-only:

Can anyone help me with a next step to make this drive read/writeable?

Turns out that the Drobo needs to be plugged straight into computer. I had it via hub. Though it has worked for the past couple weeks in this configuration, the new update pushed it over the edge, I guess. Plugged in directly and working fine.

Any suggestions?

Data Sheet View - Cannot Connect to Server at This Time. You can continue working with this list, but some data may not be available

After a couple of years of trouble free operation, one of the lists in our SharePoint Foundation site suddenly (overnight) started presenting the error against Datasheet views on lists.
The view returns a large number of items when working correctly c.6K - however Throttling Settings have been adjusted accordingly some time ago without detrimental affect on SharePoint users and network in general. As admin and therefore throttling at 20k
items the error message still presents.
The view was working fine at 4:30pm Wednesday 27/3, but was returning the error at 8:30am the next morning. To my knowledge very few items (if any) had been added to the list between those times and no system level changes had been made (SharePoint,
SQL Express, or virtual Windows 2008R2 server).
The problem is most apparent on 2 lists in SharePoint. I've checked that the settings within SharePoint admin are set to deal with queries that should accommodate the
number of rows that are returned by the views associated with that list. It is still possible to create new items to the list and access data via 'standard views' that are presented with groups that are collapsed.
Items in Documents Libraries on other parts of SharePoint and within the same subsite can be accessed at what feels like pretty normal speed -though small query size
may mean the problem is masked to a large extent.
More Specific
The lists still open in Standard View -though much more slowly than was the case before the above error started to present.
List Details
Referrals Tracker (10,442 items) -the list was 10,420 something items on Wednesday when all was working fine.
LD Tracker (4,390 items)
Both lists have grown incrementally over the period of a couple of years rather than by adding a block of data to the list. Items are added/ updated one at a time using the associated
form or directly into cells within a datasheet view.
That it is also experienced against the smaller list suggests to me that the number of items in the Referrals Tracker is not the main factor here.
In attempting to resolve the issue I have managed to get datasheet views working that deliver 100 items and c2k items. Both views present much more slowly than we would normally expect.
Throttling Settings
List view limit - 12K items - has been this high for some time without damaging SharePoint performance across the company.
Actions Taken So Far (no improved performance seen)
The SharePoint Foundation WSS Content DB did was closer to the 10GB SQL Express limit earlier this month, however a clear down and rationalisation of versioning settings
was undertaken to ensure that did not become a problem going forward.
We did a Shrink on Thursday (the day the issue started presenting) to rationalise whitespace as all indicators were that this was where the problem may lie, but this has
not resolved the problem.
The WSS Content DB now sits at c5.5GB.
What I Need to Know
1) I'd like to understand what is causing the problem?
2) What the fix is? or,
3) How I might go about diagnosing the problem further to arrive at a fix.
With all the above, I'm part wondering if the problem is related to the virtual server or poss SQL Express related rather than being a 100% SharePoint issue?

Hi
afearn,
More often this is related to columns which are not editable by user, some columns are not editable in datasheet view. Please check if there is any new column addition and then you started getting this issue.
Also datasheet view displays all items on same page so definitely it takes little long time then load in standard view.
Let us know your results, thanks

I am trying to connect to my friend's wifi, i have a very strong signal indicated on my ipad, but cannot connect to the internet. Yesterday i connected without any problem, can anybody tell me why i cannot connect today?

i am trying to connect to my friend's wifi, i have a very strong signal indicated on my ipad, but cannot connect to the internet. Yesterday i connected without any problem, can anybody tell me why i cannot connect today?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button
