Getting the ip of the user

I'm making a client server side java applet and i want to take the ip adress of the user who tries to open a socket is something like that possible if it is how?
Thanks

I made my code like this
ServerSocket servsocket = new
socket = new ServerSocket(port);
InetAddress ip =
Address ip = servsocket.getInetAddress();
String updatesql = "UPDATE onlinedestek
onlinedestek set online='1',ip='"+ip.toString()+"'
where username='"+textField1.getText()+"'";and like i said its writing the ip value as
0.0.0.0/0.0.0.0
may i fix it?Is this code from the applet or server? The server needs to listen to a server socket, and call accept. The applet needs to connect to the server socket, using a normal socket. The accept call on the server will return a socket when a connection has been established, and that socket will give you the ip-address of the applet.

How to get a formula from the user from a text box in a webpage

Hi. I would like to know how to get the formula from the user who enters in a textbox. This formula can have any number of variables starting with a and goes on.
The complexity of the formula can go upto sin, cos, ln, exp. Also user enters the minimum and maximum values of these variables. Based on a specific algorithm (which I use) I would calculate a *set of values, say 10, for each of these variables, substitute in the formula and based on the result of this formula, I select ONE suitable value for each of the variables.
I don't know how to get this formula (which most likely to be different each time) and substitute the values *which I found earlier.
Kindly help me out in this issue.
Thanks

The textbox is the easy part. It's no different than getting a String parameter out of an HTTP request.
The hard part is parsing the String into a "formula" for evaluation. You'll have to write a parser or find one.
Google for "Java math expression parser" and see what you get.
Or write your own with JavaCC.

Yosemite UPGRADE, Apps that I try to update fail with the message that connection to App Store failed, then i get a message that the updates were purchased by another user ID or purchase cancelled. All five updates have this error

AFTER I UPGRADED TO YOSEMITE, I TRIED TO UPDATE THE FIVE APPS THAT I WAS BEING NOTIFIED NEEDED UPGRADING (IMOVIE, IPHOTO ETC). I TRIED TO UPDATE VIA THE APP STORE BUT GOT A MESSAGE "UPGRADE NOT POSSIBLE WITH THIS APPLE ID BECAUSE IT WAS EITHER BOUGHT BY A DIFFERENT USER OR THE ITEM WAS REFUNDED OR CANCELLED." I DO NOT HAVE A PROBLEM SIGNING ON TO ICLOUD OR ANY OF THE OTHER SERVICES USING MY APPLE ID, I ALSO CHANGED THE PASSWORD AT THE PROMPTING. SO I'M NOT SURE WHAT IT MEANS. WHAT CAN I DO TO UPDATE MY APPLICATIONS?

Please test after each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes. Keep in mind that no one here represents Apple or can help with customer-service issues.
Step 1
A purchased app can only be updated by signing in to the App Store with the same Apple ID that was originally used to buy it. There's no way around that limitation, which also applies to free apps. If you can't sign in with the buyer's ID, delete the app and reinstall it. You'll have to pay for it again, if applicable.
Step 2
If you get the alert when trying to update a bundled iLife app, select the Purchases page in the App Store and locate the app in your purchase history. If there's a button marked ACCEPT on the right, click it.
If you have a used Mac, the bundled apps were linked to the original owner's Apple ID and can't be transferred to you. Reportedly, customer service has issued redemption codes to some second owners who asked, but it's not guaranteed.
Step 3
If you're trying to update iLife or iWork apps that were installed from a purchased DVD, or if you have a refurbished Mac bought directly from Apple, contact App Store customer service for a redemption code. You may be asked for the part number of the DVD.
Step 4
From the App Store menu bar, select
Store ▹ View My Account
Enter your Apple ID password at the prompt. At the lower right corner of the window that opens, click the Reset button. Close the window.
Step 5
According to a report, the error can result from changing the language setting of your Apple ID account. I can't confirm.

In Mail Preferences/Accounts/each GMail account, set up the SMTP Outgoing Server for each account separately, going into SMTP name/edit/Advanced and specify the Username of each account. The Outgoing servers must be two different servers, authenticated by the Username and Password of each.
Otherwise, the GMail SMTP server will change the from address to that of the account where the SMTP server was setup.

Hi, I'm a pc user and am trying to access an ical via the icloud. This ical houses information about work etc and it is quite important that I can gain access to it. To that end I have created an apple id and password and downloaded the icloud for the pc. However , when I get to the sign in page and use my apple id, I get a message to the effect that my apple id is ok, but its no good for an icloud account/ or I dont have an icloud account. I've trawled thru lots of help pages and nothing points me in the right direction. I've been on this for over 3 hours today and getting nowhere....Can somebody please help, I'm starting to lose the will to live over this

You must create the account using an Apple device, a Mac (Lion or greater) or an IOS device (IOS5 or greater). Having done that you will be able to sign in from your Windows machine.
FYI, iCal is an application that can display calendars from iCloud (and others) it is not a calendar itself, merely a calendar client. In Windows Outlook is the calendar client.

ITunes settings reset with every new version, and I get: "...the information on the iphone is synced with another user account"

Windows 7 64-bit with MS Outlook 2010. I've seen this now probably 10 times. When I first installed iTunes, I selected:
Preferences -> Devices -> "Prevent iPhonse, iPhones and iPads from syncing automatically".
and on my iPhone, I selected:
Info -> Sync Contacts with: Outlook.
Info -> Sync Calendars with: Outlook
Info -> Other -> Sync notes with: Outlook
This works great, and the settings stick. As soon as apple releases any new version (even minor) of iTunes and I install, I immediately receive: "...the information on the iphone is synced with another user account", and have to merge my calendar and contacts, but then once I get into iTunes, I find that ALL of the above settings (prevent syncing, sync calendar, contacts, notes) get reset and are turned off! I am running as a user account with Admin privaleges, but I don't right-click -> "Run as administrator" when I perform the iTunes update.
To reiterate, once I change the settings back, things work normally until the next iTunes update at which it gives me that sync error, and resets my sync options.
Any idea? Thanks!
-Brian

Is someone else using the PC and iTunes?
Create another user for the PC with your name, and try syncing that way.
This way it wont conflic with the other user.

I lost an xcel doc. Tried to find the Library folder in Users not there when use Finder. But when trying to upload a photo, iphoto found the library folder I can see my doc in Office 2011 Autorecov, but can't access it! How do I get User to show Library

I lost an xcel doc a couple of days ago. Tried to find the Library folder in Users but not there when I use Finder (even when I do shift-command-G). But when trying to upload a photo in iphoto I found the library folder in Users. I can see my doc in Office 2011 Autorecovery, but can't access it! How do I get User to show Library then I can get to my long lost document?

The auto recovery dat should be in the Microsoft User Data folder in your documents folder, not in the Library. However, I Haven't had to look recently.

Time Machine on my iMac won't open iPhoto. It goes to desktop screen automatically. When I select User/Picture/Iphoto library it only brings up the preview page with the size of the folder. I can't get into the library to look for lost photos.

Thank You. This helps me alot to get into the masters and to see events and photos in a utilitarian way, but it is not as easy as viewing the normal iphoto format to find photos. Can I do something else or did I not do something right to not see normal iphoto in Time Machine ?

Never had trouble before with my incoming mail but just now I get a messege saying the user name or password for verizon is incorrect on my iPad but is fine on my home computer what's wrong with my ipad

Never had trouble before with my incoming mail but just now getting messege that says the user name or password for verizon is incorrect yet my home computer is fine only have this od my iPad

I experienced same problem tonight and called Verizon technical support and they walked me through the settings on iPad. Took about 5 minutes. Basically it involved changing incoming.verizon.net to pop.verizon.net and changing outgoing.verizon.net to smtp.verizon.net. But it's worth the call to ensure other settings are OK. Evidently, change at Verizon was effective today!

How to I get rid of pop up user account control "do you want to allow the following program to make changes to your computer" I have windows 7 professional.

I keep getting an annoying pop up the says "User Account Control" "Do you want to allow the following program to make changes to your computer"
== This happened ==
Every time Firefox opened
== Two days after I downloaded Firefox and set as my default browser.

Check that you do not run Firefox as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
In the Compatibility tab, make sure that Privilege Level: "Run this program as Administrator" is not selected.
You also need to check the Properties of the firefox.exe program in the Firefox program directory.
If you can't make the changes then you need to start Windows Explorer as Administrator.

How can i get the list of all users present in the LDAP

Hi Experts,
How can i get the list of all users present in the LDAP ?
Is there any API or function Code to get all user list??
Please help me out!!!
Help will be rewarded

Well it will depend on exactly where your UME configuration points to in the LDAP tree but yes, it is possible to get all users. Something like the following should do it:
import com.sap.security.api.*;
import com.sapportals.portal.prt.component.*;
IUserFactory iuf;
ISearchResult isr;
IUser user
String userid;
iuf = UMFactory.getUserFactory();
isr = iuf.getUniqueIDs();
you will need to iterate the ISearchResult object but you can get IUser objects by
userid = (String)isr.next();
user = iuf.getUser(userid);
then you can imanipulate / identify / or whatever you need with the user object
