What about numbers that start with Zero
When I enter numbers that start with Zero (EX: 08794) in a cell, Numbers automatically drops the zero. I WANT THE ZERO. How can I do that. I've tried changing the formula to numerals and automatic. Same thing.
Numbers starting with zeros are usually "labels" rather than "numbers" used in further calculations. If that's the case with yours, the easiest solution is to set the format of the cells where the 'numbers' will be inserted to Text.
An alternate, useful only if all of the 'numbers' are the same length (eg. five digit zip codes) is to set a Custom format for the cell(s).
Use the Cell Format Inspector ("42" button in the Inspector) to apply either of these settings.

Blocking all numbers that start with +23
Hello,
I have a big problem, because someone from Nigeria is calling me all the time (i dont know where did they get tnis number!!!). I tried to bock their numbers, but whenever I do that, they just change the number and call again. I think I have bloked over 100 numbers, but they keep calling!
Is there any possiblity to block all numbers that starts with +23?
TnxHi,
You will not be able to do this.
If the material number is fully numeric you can only have leading zeros On or OFF, you cannot store a material number with differeing leading zeros.
If this was a new implementation you could have set the "lexicographical" flag on the material master controls and you could then have whatever leading zeros you wanted, but this flag can ONLY be set BEFORE you add your first material and so you no longer have the option.
If you really MUST have this option then define an external number range for alpha characters and use an alpha character on the end of the number, so for 00456 you would have to create 00456a and train your users to ignore the "a". This is a really bad solution but you have no option of having variable numbers of leading zeros.
Sorry

Shows I got text from numbers that start with 000
Looking at my bill. It shows I got text from 000-008-0153... What would that be from?
Staying on top of your usage is important, Jeff7777. Normally messages from a 5 or 6 digit short code are special offers from companies. Although I am unable to determine who that short code belongs to, you can opt out of premium messages by texting "Stop" to the shortcode.

What are the weird files that start with ._ that pc users get when I send zips?
When I send files that I zip using Stuiffit to pc users they get the files plus an equal number of files that start with ._ Does anybody know what these are and how to get rid of them?
Thanks!
KarenDot files are invisible files that OS X uses to display positions of files and folders icon for instance when you open a folder.
That is indeed what a .DS_Store file does, but that's not the ones Bogies is referring to.
There are various other items that start with a period, such as .Trashes. Every drive gets a trash folder, just as Windows does to each of its drives. While it hides its own trash folders from view, Windows doesn't recognize OS X's version of the trash folder, so you see it.
But you're likely talking about these. Every file you copy from OS X to a DOS/Windows formatted drive gets a ._ file. The Mac OS has a twin file system; the data fork, and the resource fork. Windows has only a data fork.
In order for OS X to maintain the resource fork data on a Windows drive, it has to write the resource data as a separate data fork file. So a file named foo.tif will also get a ._foo.tif file on the drive. Mac users don't see them since UNIX automatically hides anything that starts with a period. When you copy the file back to OS X, the data and resource fork info is combined again into a normal Mac file.
Most of the time, removing these are no big deal. They hold simple data like Type and Creator codes, modification dates, icons, etc. Others, like Mac Type 1 PostScript or Mac legacy TrueType fonts have all of the font data in the resource fork. Delete the ._ files for those types of fonts, and you're left with nothing. -

I'm having troube with music. Some artists that start with an "A" appear under the "B" menu and similarly throughout the alphabet. Same about albums, songs and genres. It suddenly happened after about 3 days of iOS 5 usage. Re-synchronization doesn't help. I also tried deleting some artists from ipod, but it doesn't help either.
1) This is because of software version 1.1. See this
thread for some options as to how to go back to 1.0,
which will correct the problem...
http://discussions.apple.com/thread.jspa?threadID=3754
59&tstart=0
2) This tends to happen after videos. Give the iPod a
minute or two to readjust. It should now be more
accurate.
3) This?
iPod shows a folder icon with exclamation
point
4) Restore the iPod
5) Try these...
iPod Only Shows An Apple Logo and Will Not Start
Up
iPod Only Shows An Apple Logo
I think 3,4, and 5 are related. Try the options I
posted for each one.
btabz
I just noticed that one of the restore methods you posted was to put it into Disk Mode First rather than just use the resstore straight off, I Have tried that and seems to have solved the problem, If it has thank you. previously I have only tried just restoring it skipping this extra step. Hope my iPod stays healthy, if it doesnt its a warrenty job me thinks any way thanks again -
How to access a JSON structure key that starts with a number
I've got an odd issue here. I'm accessing someone else's JSON structure so I am not able to change it. The JSON structure keys are named with both characters and numbers like this:
0
198456
product_id
198456
1
Rashaan Houston feat Tony Loreto
artist
Rashaan Houston feat Tony Loreto
So, in other words, there's a key named "0" and a key named "product_id", both of which contain the same key. Why they did that, I don't know, but they did.
In one of the instances, the data stored under the text-named key isn't the same as the numerical-named key. I tried to output the data in the numerical key like this (it's an array of structures):
#strStompyJSON.data[1].0#
but I get the following error:
Invalid CFML construct found on line 41 at column 31.
ColdFusion was looking at the following text:
.0
When I do the following, it works fine:
#strStompyJSON.data[1].product_id#
So it looks as though CF doesn't like accessing a variable that starts with a number. I am able to loop through the structure using a collection loop, and it outputs all of the keys (including the numerical ones) and their values using the following code:
<cfloop collection="#strStompyJSON.data[1]#" item="key">
#key#: #strStompyJSON.data[1][key]#<br />
</cfloop>
However, that doesn't allow me a way to access specific keys named with a number. Is there a way that I can specifically access a key that is named with a number?
thanks!
MikeNo problem--glad it worked out.
As a follow-up to this, I'd encourage you to keep the bracket notation in mind during future development. It is EXTREMELY useful in a lot of situations.
For example, if you're building a structure on the fly with dynamic keys, bracket notation is extremely helpful:
<cfset authors = structnew()>
<cfloop list="authorlist" index="name">
<cfset authors[name] = getbooklist(name)>
</cfloop>
Also, bracket notation is really nice when creating json from ColdFusion structures. Consider this:
<cfset author = structnew()>
<cfset author.name = "Neil Gaiman">
<cfset author.genre = "Fantasy">
<cfset author.awesome = true>
<cfset authorjson = serializejson(author)>
By default, the serialized json produced will have all UPPER CASE keys. Not a big deal in most cases, but if you're returning the json to something (like a JS library) that is expecting keys in a certain case, it can be a problem. Fortunately, bracket notation allows you to specify exactly what case you want the structure's keys to be in:
<cfset author = structnew()>
<cfset author['name'] = "Neil Gaiman">
<cfset author['Genre'] = "Fantasy">
<cfset author['AWESOME'] = true>
<cfset authorjson = serializejson(author)> -
RSA decryption Error: Data must start with zero
Because of some reasons, I tried to use RSA as a block cipher to encrypt/decrypt a large file. When I debug my program, there some errors are shown as below:
javax.crypto.BadPaddingException: Data must start with zero
at sun.security.rsa.RSAPadding.unpadV15(Unknown Source)

Moderator action : added [ code] tags so as to make the code readable. Please do this yourself in the future.
Edited by: 949003 on 2012-8-3 上午5:311) Why are you not closing the streams when writing the keys to the file?
2) Each block of RSA encrypted data has size equal to the key modulus (in bytes). This means that for a key size of 1024 bits you need to read 128 bytes and not 64 bytes at a time when decrypting ( this is probably the cause of your 'Data must start with zero exception'). Since the input block size depends on the key modulus you cannot hard code this. Note - PKCS1 padding has at least 11 bytes of padding so on encrypting one can process a maximum of the key modulus in bytes less 11. Currently you have hard coded the encryption block at 64 bytes which is OK for your 1024 bits keys but will fail for keys of modulus less than about 936 bits.
3) int size = dataFIS.available(); is not a reliable way to get the size of an input stream. If you check the Javadoc for InputStream.available() you will see that it returns the number of bytes that can be read without blocking and not the stream size.
4) InputStream.read(byte[]) does not guarantee to read all the bytes and returns the number of bytes actually read. This means that your code to read the content of the file into an array may fail. Again check the Javadoc. To be safe you should used DataInputStream.readFully() to read a block of bytes.
5) Reading the whole of the cleartext or ciphertext file into memory does not scale and with very large files you will run out of memory. There is no need to do this since you can use a "read a block, write the transformed block" approach.
RSA is a very very very slow algorithm and it is not normal to encrypt the whole of a file using it. The standard approach is to perform the encryption of the file content using a symmetric algorithm such as AES using a random session key and use RSA to encrypt the session key. One then writes to the ciphertext file the RSA encrypted session key followed by the symmetric encrypted data. To make it more secure one should actually follow the extended procedure outlined in section 13.6 of Practical Cryptography by Ferguson and Schneier. -
Javax.crypto.BadPaddingException: Data must start with zero
Actually, I didn't write the entire codes, most of it was written by someone here, and I only tried to add a method. Here:
public class RSAEncrypt {
private KeyPair keys;
private Cipher rsaCipher;
public RSAEncrypt() throws GeneralSecurityException {
KeyPairGenerator keygen = KeyPairGenerator.getInstance("RSA");
keygen.initialize(512);
keys = keygen.generateKeyPair();
rsaCipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");
public byte[] encrypt(byte[] message) throws GeneralSecurityException {
rsaCipher.init(Cipher.ENCRYPT_MODE, keys.getPublic());
return rsaCipher.doFinal(message);
public byte[] decrypt(byte[] encryptedMessage) throws GeneralSecurityException {
rsaCipher.init(Cipher.DECRYPT_MODE, keys.getPrivate());
return rsaCipher.doFinal(encryptedMessage);
* @param args
public static void main(String[] args) throws Exception {
String message = "The quick brown fox ran away";
System.out.println("Message: " + message);
byte[] encrypted = new RSAEncrypt().encrypt(message.getBytes());
System.out.println("Cipher Text: " + HexBin.encode(encrypted));
byte[] decrypted = new RSAEncrypt().decrypt(encrypted);
System.out.println("Decrypted Text: " + decrypted);
}The idea is that the program should encrypt the String, "The quick brown fox ran away," which it does. But when it gets to this line:
byte[] decrypted = new RSAEncrypt().decrypt(encrypted);i get the error: javax.crypto.BadPaddingException: Data must start with zero.
But here's the funny thing: If I edit the codes so that the encryption and decryption are done in the constructor, it works! Here:
public class RSAEncrypt {
private KeyPair keys;
private Cipher rsaCipher;
public RSAEncrypt() throws GeneralSecurityException {
KeyPairGenerator keygen = KeyPairGenerator.getInstance("RSA");
keygen.initialize(512);
keys = keygen.generateKeyPair();
rsaCipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");
rsaCipher.init(Cipher.ENCRYPT_MODE, keys.getPublic());
String message = "The quick brown fox ran away";
byte[] cipherText = rsaCipher.doFinal(message.getBytes());
System.out.println(new BASE64Encoder().encode(cipherText));
rsaCipher.init(Cipher.DECRYPT_MODE, keys.getPrivate());
byte[] decryptedText = rsaCipher.doFinal(cipherText);
String dText = new String(decryptedText);
System.out.println(dText);
* @param args
public static void main(String[] args) throws Exception {
new RSAEncrypt();
}So, I'm confused. The Data must start with zero error is coming up when I pass encrypted data to a method for decryption, but it doesn't come out when I run everything in one method or in the constructor. Why???
Also, when performing RSA encryption (or decryption) on a plaintext stored in a file (not a big file, just a file with probably one or two lines), this is what I do (and it works):
Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");
cipher.init(Cipher.ENCRYPT_MODE, pubKey);
CipherInputStream cis = new CipherInputStream(new FileInputStream(new File("message.txt")),cipher);My question is, I do see some people doing this as well:
cipher.doFinal(byteArray);The fact that I don't have this in my code when encrypting data from a file, that's ok, right? I don't need to do a ".doFinal()" method, do I?

I never used Win7, so I don't know if that version of Notepad messes with the line formatting of prefs.js or not.
Another thing - make sure '''''"Hide extensions for known file types"''''' is de-delected in Windows file / folder options > view -> advanced settings. Otherwise Windows may add a .txt file extension that you won't be able to see, and that will break that file in Firefox. '''prefs.js.txt''' won't be recognized by Firefox, when is expecting to find '''''prefs.js''''' . -
Possible bug in iTunes 8 adding folders that start with '..'
So I discovered tonight when trying to load tracks into iTunes from a folder that started with '...' (specifically, '...andjustice_forall'). iTunes did nothing. No reaction whatsoever. If I try to load the mp3s in that folder directly, they load fine, but it ignores the whole folder if I try to add it to the library.
I tried to replicate the issue with another folder that also started with '...' ('...andyou_will_know_us_by_the_trail_ofdead'). Has anyone else observed this behaviour? I have a feeling if it's in iTunes 8, it's been around for a while. I'm guessing it's treating the first dot as an indication that the file's a hidden file, and then ignoring the rest of the name.
Can anyone else replicate this? I was loading files from an SMB share served by a Linux host.
cheers,
KlausI just sent feedback as suggested, hope this helps. What bothers me is that these songs were visible in previous versions of ITunes. I'd actually feel better if there were a setting I just missed that would explain the weird behavior.
Looking through support topics, I specifically did a search using ".38 Special" and found an article concerning the order in which Itunes displays artists, with .38 Special being at the top of the list in the example... so that also tells me that it SHOULD be showing them. sigh -
Can Check Number be start with zero?
Dear all,
I knew that check number on SBO is numeric but check number of my country some number can start with zero and it effected to check number printing form. So, I'm not sure whether we can set check number to be charactor or not. Or how to apply for this issue, pls. suggest.
Thanks you very much.
AngnamHi,
It is not possible to set check number as alphanumeric, you can use remarks field to enter check number or any other filed that you think is not required and can be used as check number.
it is not possible to add UDF in checks for payment . if you are using payment method checks tab, you can use UDF.
Thanks,

Four digit numbering system starting with 0001 and not just 1.
How can I re name and renumber a file of photos and include a four digit numbering system starting with 0001 and not just 1. I need this so another computer program can keep the images in numerical order
Now I number a wedding say... Smith_Jones 1 ect up to 659 but a program I use to create albumes scrambles all my photos becasue they say the numerical system has to have 4 digits so Number 1 is really 0001 thus staying in order. I d ont see how to assign 3 zeros to the front of numbers --- so # 344 would be 0344 LR wants to keep it 344.In the Library rename use the following custom settings.

Copy all the objects from the one system that start with (ZANK)
hi to all,
I have installed the name space /ank/ in the US system, we need to copy all the objects from the India system that start with (Zank) and re-create them as /ank/. problem is how can i copy objects and re-create.
thanksHi Ankal,
I guess this is your second thread on the same question. Ok provide these information
>>I have installed the name space /ank/ in the US system,
Are you saying that you have a machine (US System) and i has a namespace /ank/ ? What all objects are there in this namespace?
>>we need to copy all the objects from the India system that start with (Zank) and re-create them as /ank/.
Is the India system on the same US system?
Also tell me whether you have opened the home page of SAP XI/PI? If yes , are you able to open Integration Repository? If yes then how these US and India systems are referred in Integration Repository? Are they referred as separate software components?
