  • iPhone NSDate - get time in milliseconds and store in coredata

    - by satyam
    I'm implementing iphone app with coredata functionality. I've an attribute in entity "NSDate" which stores the date and time when the record is added. I'm adding records at a faster rate. About 1 record per 25 milli seconds I want to store the date along with milli seconds so that I can retrieve the data in descending order. How can I do this?

  • SYSTEM_HANDLE_INFORMATION structure

    - by striker
    From where does this structure originates? I know that it is declared in famous ntdll.h and is a part of undocumented windows API. But isn't it vary between different versions of windows? Is there a way to dump this structure from working system? I tried 'dt SYSTEM_HANLDE_INFORMATION' in Windbg and 'type SYSTEM_HANLDE_INFORMATION' in SoftIce but all I get is 'no such symbol' message. I also dumped ntoskrnl.pdb with PdbDump.exe and searched among the dumped structures - and could not find neither SYSTEM_HANLDE_INFORMATION nor SYSTEM_HANLDE. Could you help me?

  • [Java] RSA BadPaddingException : data must start with zero

    - by Robin Monjo
    Hello everyone. I try to implement an RSA algorithm in a Java program. I am facing the "BadPaddingException : data must start with zero". Here are the methods used to encrypt and decrypt my data : public byte[] encrypt(byte[] input) throws Exception { Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");// cipher.init(Cipher.ENCRYPT_MODE, this.publicKey); return cipher.doFinal(input); } public byte[] decrypt(byte[] input) throws Exception { Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");/// cipher.init(Cipher.DECRYPT_MODE, this.privateKey); return cipher.doFinal(input); } privateKey and publicKey attributes are read from files this way : public PrivateKey readPrivKeyFromFile(String keyFileName) throws IOException { PrivateKey key = null; try { FileInputStream fin = new FileInputStream(keyFileName); ObjectInputStream ois = new ObjectInputStream(fin); BigInteger m = (BigInteger) ois.readObject(); BigInteger e = (BigInteger) ois.readObject(); RSAPrivateKeySpec keySpec = new RSAPrivateKeySpec(m, e); KeyFactory fact = KeyFactory.getInstance("RSA"); key = fact.generatePrivate(keySpec); ois.close(); } catch (Exception e) { e.printStackTrace(); } return key; } Private key and Public key are created this way : public void Initialize() throws Exception { KeyPairGenerator keygen = KeyPairGenerator.getInstance("RSA"); keygen.initialize(2048); keyPair = keygen.generateKeyPair(); KeyFactory fact = KeyFactory.getInstance("RSA"); RSAPublicKeySpec pub = fact.getKeySpec(keyPair.getPublic(), RSAPublicKeySpec.class); RSAPrivateKeySpec priv = fact.getKeySpec(keyPair.getPrivate(), RSAPrivateKeySpec.class); saveToFile("public.key", pub.getModulus(), pub.getPublicExponent()); saveToFile("private.key", priv.getModulus(), priv.getPrivateExponent()); } and then saved in files : public void saveToFile(String fileName, BigInteger mod, BigInteger exp) throws IOException { FileOutputStream f = new FileOutputStream(fileName); ObjectOutputStream oos = new ObjectOutputStream(f); oos.writeObject(mod); oos.writeObject(exp); oos.close(); } I can't figured out how the problem come from. Any help would be appreciate ! Thanks in advance.

  • Exporting data from a YUI DataTable

    - by Bears will eat you
    What's the easiest/fastest way to grab data out of a YUI DataTable and turn it into a single CSV or TSV string? I basically just want to implement a one-click way to get the entire DataTable (it should preserve the currently-applied sorting) into a form that users can paste into a spreadsheet. My DataTable can get pretty big - 5000 to 10000 rows, 5 to 10 columns - so efficiency does matter.

  • Using constructor to load data in subsonic3?

    - by Dennis
    I'm getting an error while trying to load an record through the constructor. The constructor is: public Document(Expression<Func<Document,bool>> expression); and i try to load a single item in like this var x = new Document(f=>f.publicationnumber=="xxx"); publicationnumber isn't a key but tried making an it an unique key and still no go.. Am i totally wrong regarding the use of the constructor? and can someone please tell me how to use that constructor? The error i'm getting is: Test method TestProject1.UnitTest1.ParseFileNameTwoProductSingleLanguage threw exception: System.NullReferenceException: with the following stacktrace: SubSonic.Query.SqlQuery.Where[T](Expression1` expression) Load`[T]`(T item, Expression1expression) db.Document..ctor(Expression``1 expression) in C:\@Projects\DocumentsSearchAndAdmin\DocumentsSearchAndAdmin\Generated\ActiveRecord.cs: line 5613 rest removed for simplicity Regards Dennis

  • Easiest way to export a route stored in a SQLite database to a file so it can be imported to a Googl

    - by LordSnoutimus
    Hello, I have created an application that records a series of longitude and latitude values in a SQLite database and display them as a coloured track on a MapActivity. I now want to be able to export this data somehow (preferably to a file) so a user can upload the values to a website showing a Google Map API. My question is: what would be the quickest way to export the data (and in what file format: GPX, XML, CSV) to the SD card located on the Android device. Many thanks.

  • Recover Data Entered in MSSql 2008 to MSSql 2005

    - by Nirmal
    Hello... I have created a set of tables (around 20) in MSSql 2008 and entered around 1000 records to appropriate tables. But the issue is that I want that same tables with all the entered data into MSSql 2005 (SQLEXPRESS). Obviously it won't work by taking a backup and restore it into MSSql 2005 as it won't support backward compatibility. Any suggestion would be appreciated.... Thanks in advance....

  • SSIS how to split a single record in to two different records?

    - by Dr. Zim
    I have a Product record that has multiple "zoned" prices, one for each store that sells the product. ProductID int Name string PriceA money PriceB money PriceC money In SQL Server Integration Services, I need to split this in to multiple records: ProductID int Version string // A, B, or C Price money // PriceA if A, PriceB if B, etc. This would be within a Data Flow, I presume as a Transformation between Excel source and OLE DB destination. (Assuming OLE DB is a good destination for MS SQL server).
