How can i validate items in java

hi....
how can i validate items in java....so that user can not type in characters
in the place of number????
please help?!?

Hope u know getText() method returns string
i.e text1.getText() returns string.
U need to convert the string to integer with integer class. Go
to the documentation to search for it.
Then attach a conditional statement stating if not numeric
, then not valid. if u have little knowledge of java, u will understand it.
Otherwise, wait till tomorrow bcos I'm late for xmas carol.

How can i validate an untouched cell and change bground color if error

Hi ,
three questions
1. I can validate data in cells in setValueAt method but the cell data will be validated only if user click on that cell.
how can i validate another cell if user does not even touch it.
2. and if error how can i change background color.
3. i have JTextField for column as cell editor/renderer. To change the data user have to double click on cell. How can I make it to click once to edit the value in the cell.
Thanks in advance for help.

how can i validate another cell if user does not even touch it.
Why would you want to validate a cell if a user doesn't change it?for example user clicked Add row, and i added a row in the table with blank information...so .all cells in the new row have blanks, so if user does not enter the data in the second column... which he did not touch...i want to catch it and produce error
How can I make it to click once to edit the value in the cell.
Something like this:
DefaultCellEditor dce = (DefaultCellEditor)table.getDefaultEditor(Object.class);
dce.setClickCountToStart(3);Thank you..

How can i validate input number into a Field of type char in oracle form?

How can i validate input number into a Field of type char in oracle form?

i have tried doing that, but still the field except numbersthere was an error in that code. it should have been
var_num:=to_number(var_char);however, it appears that you want the entry NOT to be a number. if this is the case then try
begin
if to_number(:block.item) = 0 then null; end if;
message('The entry cannot be numeric');
raise form_trigger_failure
exception
when value_error then
/* this is where you put the code you want to be run when the
entry is non-numeric */
end;

How can I validate my XSD programatically ?

Hi,
I know how to validate XML against an XSD. But how can I validate an XSD itself? i.e Programatically press the "validate" button in XML Spy.
I have tried validating it against http://www.w3.org/2001/XMLSchema.xsd . But this does not work for imports. i,e MySchema.xsd imports CommonSchema.xsd and uses CommonSchemas element definitions.
When I validate against XMLSchema.xsd it does not check the imports.. i.e i can delete an import statement and its still valid - and in this case it obviously shouldnt be.
Anyone any ideas?
Cheers,
Alan

Hi Caffaine,
sounds like a difficult problem... I tried to do something similar to this a few years ago under Java 1.3, and I can tell you that you'll have a couple of problems.
1) ResourceBundles are a type of cache, so the one you load first is the one you are stuck with for the remainder of the program execution. The only ways around that AFAIK is to either author your own non-static ResourceBundle, or to have the user re-execute the client every time they want to change locales (neither of which is particularly appealing). Not sure if anything in Tiger has rectified this, but I don't think it has.
This also means that your server will be stuck in a certain locale. Probably the best thing to do would be to write your clients so that all information heading back to the server heads there in Unicode, so that you're dealing with a common encoding on the server side. This means no bytes or chars. Strings would be the thing to use.
2) AFAIK, Java has no way of programatically changing the Windows input locale. Though if I am wrong, someone please correct me!
Hope that helps!

How can I validate an X509Certificate ?

I'm not really sure of what makes a certain cetificate different from a certificate that I create in my comupter... I mean, how can I validate that a certain certificate belongs to the entity it says it belongs to?
Is my question clear enough?
I hope someone can help me with this...

Hello,
You do not validate certificates per say, they are either valid or they are not.
Certificates contain a certificate chain/path leading back to a certification authority. Your computer/java has a list of trusted authorities. If the afore mentioned path does not lead back to one of them, authenticity (of software/documents) amongst other things can not be gauranteed. In this case, you would contact the publisher of the cert and verify it is them by comparing keys.
Yes you can create you own certificate and distribute it, but you will be the one to handle all requests to verify that the pub.key in the cert is actually yours.
I hope this has cleared it up... and is accurate for that matter (if anyone cares to point out).
Warm regards,
Darren

How can i remove items from list that have been deleted when i click on them it keeps showing empty

how can i remove items from the list that have been deleted when i click on them it keeps showing folder empty

Actually, Reader SHOULD keep showing documents that no longer exist, I disagree. It's no big deal, and people will quickly realise why they can't open the file. They open more files, the old ones move off.
The REASON why it should not check is that checking whether a file exists can take a long time when things aren't good. For instance if a file server goes down, or a memory card is unplugged. That in turn would mean delays opening the File menu, and I've seen some software that can sit there for several minutes. That would really give people something of which to complain...

It is for Acrobat, but the registry entries are similar for Reader.

How can I validate my warranty with a refurbished iphone?

On August 28th I visited Miami and I went to the Apple Store to replace my Iphone 4 broken out of warranty with a Refurbished Iphone.
The problem is that the refurbished Iphone replacement never worked! I tried to verify my coverage status but it is out of warranty. I know that there are 90 days of warranty. However, how can I validate this warranty because the IMEI is not accepted to chat or contact Apple Support? Somebody can help me?
Thank you

According to your original post, your limited warranty is scheduled to expire on November 28th. That service replacement warranty was never intended to include live support via chat or phone conversations with an AppleCare advisor.

How can I open items made with apple works

How can I open items made with apple works

You need to purchase Pages for your iMac. You can buy it from the App Store.
I don't know if the version of Pages for the iPad will open the Apple Works documents. If you have the documents on your Mac and want to open them on your iPad the easiest way I can think of is to open a DropBox (Google it) account and store the documents there. Then you can try to open the documents in Pages on your iPad. If that doesn't work then I know Pages for OS X will open the Apple Works WP documents.
