NumberFormatException plz help...

have encountered a NumberformatException and I am giving stacktrace
at java.lang.NumberFormatException. 0(NumberFormatException.java:48)
at java.lang.Long.parseLong(Long.java:415)
at java.lang.Long.<init>(Long.java:630)
at domaintt.main(domaintt.java:29)
It occurs in the given statement
Long duration =new Long(form.getDuration()) /* getDuration() returns a string which is equal to no of hours */
I want to replicate this Exception with some sample data.I.e like
Long l = new Long("uuu");
I am able to produce the Exception but in some other format like
java.lang.NumberFormatException: For input string: "uuu"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
at java.lang.Long.parseLong(Long.java:415)
at java.lang.Long.<init>(Long.java:630)
at domaintt.main(domaintt.java:29)
if i give
Long l =new Long("0"); it's not thowing exception as expected.Then in what scenario
java.lang.NumberFormatException. 0(NumberFormatException.java:48)
will occur.I am unable to replicate and i do not understand In case of '0'
how it will thowing exception.
I am wondering why in case '0' it is throwing Exception and any way I am passing string as parameter.so Stack trace should be as
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
at java.lang.Long.parseLong(Long.java:415)
at java.lang.Long.<init>(Long.java:630)
at domaintt.main(domaintt.java:29)
but it is not like that.
Thanks,

Hi when i open my application folder, all the application is shown in trash folder. when i click the application it says this app is in trash first move it out. and when i try to open through finder go it says this file doesn't exist. can some1 plz help?

hi when i open my application folder, all the application is shown in trash folder. when i click the application it says this app is in trash first move it out. and when i try to open through finder> go it says this file doesn't exist. can some1 plz help? how can i put all my application through application folder?

Something really odd is going on. In your first screen shot, I noticed that the Applications folder does not have the proper icon displayed in the side bar. Also, in the title bar it lists it as Applications 08-59-29-909.
Not sure where it's picking up that odd name, unless it's because it's still truly within the Trash folder.
Try this. In the Finder > Preferences > General > turn on "Always open folders in a new window". (I have a feeling you have the default setting with this off).
Now, in Finder > Go > move down and open the Applications Folder from there. Now open the folder where you see all your applications that you show in your screen shot, select all, and move them to this true appliactions folder.
This is what you should properly seeing (but with different apps listed):
See how the Applications folder has the icon of the letter A shaped with a pencil, ruler & pen.

How to print text/data in flex 3 using printer???Plz help...

   Hi,
          plz tell me the way to print text/data using printer in flex. I tried the FlexPrintJob class. but it takes object of a container to be printed & prints the visible content of that container(along with scrollbars), bt i want to print all contents of the container(including invisible).
      I have tried to print bitmap image through FlexPrintJob but it takes lot of time for spooling... So plz help me out in printing(fast with all content) in flash
I am using flex 3 (flex Builder 3 IDE).
Thanks in advance!!!

Hi Sagar,
Don't worry You can use the below work around to print all the contents of the Container including the invisible contents under scrolll with out scroll bar..
So what the idea here is we are seeting the container height to full size with out scrolls before sending the container object to printer and as soon as you print the object you are restoring it to the original height with scrolls...so that you can print the full contents without scrolls...
You may have doubt that by chnaging and restoring the size the user may see momentary resize of the container but it is not so as it is a fraction of a second and user cannot notice this change... Give it a try ..I had already run into this problem recently and I have found a work around for this which is as below:
// Here mainContainer is the container or box id the contents of which you want to print
   private function doPrintContainer():void
    var printJob:FlexPrintJob = new FlexPrintJob();
    if(printJob.start() != true) return;
    try
     var mainContainerHeight:int = mainContainer.height;
     //Increasing the height of the desired component to be printed.
     mainContainer.height = mainContainer.measuredMinHeight;
     mainContainer.verticalScrollPolicy = "off";
     //Adding the resized Component to our FlexPrintjob and then sending the print request
     printJob.addObject(this,FlexPrintJobScaleType.MATCH_WIDTH);
     printJob.send();
     //Resizing the component back to normal size
     mainContainer.height = mainContainerHeight;
     mainContainer.verticalScrollPolicy = "auto";
    catch(error:Error)
                 trace("Error : " + error.message);

You said you updated yur 1G iPod to 4.2.1. A 1G can only go to 3.1.3 and thus you must have jailbroken it to get to 4.2.1 and that can cause problems.

I have the same problem.. apps won't download and won't open. I have a 1st Gen ipod touch and recently upgraded my MacBook Pro (2012) and as soon as I upgraded the iPod Touch to 4.2.1, this happened.

Apple tech charges $29.99 for out of warranty products and if I am reluctant to pay with them telling me its simply a hardware problem.

I restored my Macbook Pro and now I can't log in as Admin - it says there is an error with FileVault and I don't have access - plz help! thank you.

I had to restore my Macbook Pro from Time Capsule yesterday and now when I go to log in as my usual Admin, it says there is a FileVault error and my access is denied. I created another temporary Admin acct, but everything I had on my desktop, etc is "gone" I can look up the "drive' or wahtever it's called, but I can't access any of it. All I want to do is log back in as my usual self (the regular Admin) - plz help! Thanks. p.s. I"m (obviously) not that computer savvy!

Triple-click the line below to select it:
/System/Library/CoreServices/Directory Utility.app
Rght-click or control-click the highlighted text and select
Services ▹ Open
from the contextual menu.* The application Directory Utility will open.
In the Directory Utility window, click the lock icon and authenticate. Select the Directory Editor tool in the toolbar. Select Users from the Viewing menu in the toolbar, if not already selected. Select the affected user account in the list. On the right is a list of properties and values. Select the property "HomeDirectory" and delete it by clicking the minus-sign icon directly below the property list. There are two such icons in the window. You want the one on the right, not the one on the left.
CAUTION: Do not click the minus-sign icon on the left, below the user list.
Then click the Save button in the lower right corner of the window. Quit Directory Utility.
CAUTION: There is no "undo" in Directory Utility. If you make a mistake and delete something in the Directory Editor that should not have been deleted, restore your whole system from a backup and start over. I have no other help to offer in that case.
Try again to log in as the affected user. If you can log in, you should find a file in the home folder with the name of the user and the filename extension "sparseimage" or "sparsebundle". Double-click that file. A disk image should open. Copy your files from that disk image to restore them.
I strongly suggest that you deactivate legacy FileVault in the Security & Privacy preference pane, then log out and log back in. Consider activating FileVault 2 if you want that kind of security.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). Open a TextEdit window and paste into it (command-V). Select the line you just pasted and continue as above.

Error in variables,plz help me

I created a variable del_var.The sql query assosiated with this variable is.
Delete from schema.file_name_table where rownum=1;
After refreshing it.it is deleting first row in the table.But it is resulting in an error
"17003 : null : java.sql.SQLException: Invalid column index java.sql.SQLException: Invalid column index "
Plz help me

Hi,
You can't use a 'Delete" command at a refreshing variable because at a refresch the variable need to receive a value back and the delete doesn't return value.
Change the command to "select....."
Does it make sense to you?

Had 1418 error.formatted as fat.not fat32.now ipod doesnt work.why?plz help

The iTunes keeps saying that:
"The iPod "IPOD" cannot be updated. The disk could not be read or written to"
"The iPod "IPOD" cannot be updated.
And when I tried to restore it.
"The iPod "IPOD" could not be restored. An unknown error occurred (1418)"
thats a dreaded problem and i researched at many forums on how to solve it.....
before reading ur reply....there were some other replies that i read.....
which told me to format my ipod into fat partition...and not fat32 partition....then we had to update it and then restoring it would be possible........
that was the only article which i came across and which had a solution to 1418 problem......
so i began my work....
but as soon as i formatted my ipod shuffle second generation into fat partition.......
i restarted my comp...and then.the ipod is no longer working.......
if i push it to on......then there is a constant green light on it which does not go off even if i connect it to comp. using the dock provided.......
if i put it off,the green light goes off....
ideally when an ipod shuffle is connected to pc..there is an orange light that starts blinking ,that shows that the ipod is being charged.
but now when i connect mine.....
the green light blinks only once......and then nothing happens...
the device isnt working and so i cant even solve my 1418 problem ,as now i even have the solution.......
help me plz....
its really urgent....
its been just a month my uncle gifted me this ipod ...he stays in north carolina........and i stay in india.....
i dont even know if there are service centres of apple available in mumbai.and if they are,whether they are trust worthy or the ipod that i send to them might never to me and get stolen or something.....somebody might just keep it and say that its lost.......mumbai is not trustworthy.
but if there is a recognized apple service centre then i would want to go there and get my ipod repaired....i have one-year warranty with me.......but i dont know if the warranty of a product bought in north carolina works in india......
i cant throw this ipod....cause its my first ipod and it has hardly been time that i got it...its too early for me to throw it.....
i dont know why the ****.....cant i connect it to the comp...
i tried the following: after getting 1418 read and write error...:
reinstalled the itunes 7.0.2
reinstalled the drivers......
reset the ipod shuffle...
restarted my computer several times.....
checked the cable....
plugged the usb cable onto another port...
scanned the comp for viruses......
now the only thing left is that i think.....there can be a problem with the jack where the dock is plugged.....
maybe thats the reason my ipod isnt working...
even if i formatted into fat partition rather than fat32 partition,it should atleast be connected......
should atleast charge.....
should atleast be detected......
my ipod is not even getting detected by the comp as any unknown device also.....forget as an ipod....
i just shouldnt have formatted it...
although i think....that formatting it did not lead to this problem......
please help me.......
urgently...........
plz.....
plz......send ur reply fast..plz help me.........
get this ipod to work......
i will fix the 1418 error myself....
just get this device to work....so that comp starts detecting that i have connected something thru usb.....

On top of the two suggestions already given, make sure that the drive letter being assigned to the ipod when you plug it in in windows is not also a drive letter being assigned to another drive. I've heard that this happens occasionally and can cause all kinds of conflicts, from problems you are describing to lockups when trying to sync.
I would also try it on a different computer to see if that helps. Maybe you've got a friend or a computer at work that you can install itunes on and give it a shot there. This will let you know whether it's a problem with your specific computer or if it's a problem with the ipod.
The fact that it runs in Windows and you were able to reformat the flash memory stick tells me that the Ipod is working, but that something on your computer is not.
P.S. Obviously you've had it for 90 days, So I must assume that the USB port is working correctly. Otherwise the Ipod's battery would have drained by now. So I don't believe it is a hardware issue. So move past that for right now and look to your computer's settings for the answer.

I created an iCloud account and also had to get more space after I have done the purchase, I am unable to backup my phone! I have a stable wifi connection at home and all I see for hours and hours is "Backing Up .. Estimating time remaining"!!!!! Plz help

I created an iCloud account and also had to get more space so after I have made the purchase, I am unable to backup my phone! I have a stable wifi connection at home and all I see for hours and hours is "Backing Up .. Estimating time remaining"!!!!! Plz help I'm unable to make the backup as I need to transfer all my data on my new iPhone 5S

This may be caused by a corrupt existing backup that needs to be deleted, or by data on your device that is causing the backup to fail. To troubleshoot these, try deleting your last iCloud backup (if you have one) by turning off iCloud Backup in Settings>iCloud>Storage & Backup, then tap Manage Storage, tap your device under Backups, then tap Delete Backup. Then go back and turn iCloud Backup back on and try backing up again.
If it still won't back up, you may have an app or something in your camera roll that is causing the backup to fail. To locate which one, go to Settings>iCloud>Storage & Backup>Manage Storage, tap the name of your device under Backups, under Backup Options tap Show All Apps, then turn them all to Off (including camera roll) and try backing up again. If the backup is successful, then the camera roll and/or one of your apps is causing the backup to fail and you'll have to located by process of elimination. Turn the camera roll On and try backing up again. If it succeeds, turn some of your apps to On and try backing up again. If it succeeds again, turn some more apps to On then try again; repeat this process until it fails. Eventually you'll be able to locate the problem app and exclude it from your backup.
In the meantime you can back up your phone to your computer by connect it, opening iTunes and going to File>Devices>Back Up. Also be sure to transfer your purchases (File>Devices>Transfer Purchases). Then set up your new phone and when given the option, choose Restore from iTunes Backup and follow the prompts to restore this backup to your new phone. This will be much faster than using iCloud anyway.

My recirculating pump in sub vi simulation link doesnt work in the second iteration .It opens for maybe half a second whereas i gave the time delay for 5 secs..plz help very urgent

Hi,
I have attached my simulation loop.In the model attached i hav eone main pump with constant rpm which drives the 5 smaller pumps and fills the tank at the same time.As soon as the tanks reach their 90% level,the valves of the five pumps close(SP1,SP2,SP3,Sp4,Sp5).After that the recirculating pumps opens for 5 secs of the first tank.As soon as the recirculation finishes,the drain valve(SV1) for tank 1 open and the volume goes to interim storage.This happens for all the remaining tanks.
My simulation works the first time,but when the second time the loop starts,it skips the recirculation pump even though i gave a time delay for 5 secs.Plz help ..I have attached the simulation.
Thanks,
Rami

Spatial Logic_2_Final.vi ‏223 KB

Rami,
I suspect that you have a race condition. The widespread use of local variables frequently leads to race conditions. Your subVI (Spatial Logic Sub_2.vi was not included) so I cannot run the VI. You have no way of knowing whether the subVI or the inner case structure will execute first, because there is no data dependency between them.
I think a shift register or a few and some dataflow thinking would allow you to eliminate the inner case structure, the local variables, and, probably, most of your problems.
Some of the SPi are indicators and some are controls. How are they used?
The last case of the inner loop retursn to Case 1. Would case 0 be better?
As for the second time through issue, it may be related to the Elapsed time function Auto Reset. From the help file: "Resets the start time to the value in Present (s) when the Express VI reaches the Time Target (s)." If more than 5 seconds elapses between the first time you use this and the next, it will exit immediately on the subsequent calls.
