  • stdout and stderr character encoding

    - by Muhammad alaa
    i working on a c++ string library that have main 4 classes that deals with ASCII, UTF8, UTF16, UTF32 strings, every class has Print function that format an input string and print the result to stdout or stderr. my problem is i don't know what is the default character encoding for those streams. for now my classes work in windows, later i'll add support for mac and linux so if you know anything about those stream encoding i'll appreciate it. thank you.

  • Diffplex wrapping long lines with diff highlights

    - by MicMit
    http://diffplex.codeplex.com/ I am looking at the samples provided. In these samples for the long lines they are trying NOT to wrap them which leads to horizontal scrolling. I believe, it should be possible to show those lines wrapped inside cells. In my scenario for left and right strings as input, after calling DiffPlex I just need them modified with html styles to be placed into table cells with wrapping.

  • How to improve performance of Jquery autocomplete

    - by Bjorn
    Hi, i was planning to use jquery autocomplete for a site and have implemented a test version. Im now using an ajax call to retrieve a new list of strings for every character input. The problem is that it gets rather slow, 1.5s before the new list is populated. What is the best way to make autocomplete fast? Im using cakephp and just doing a find and with a limit of 10 items. Cheers Bjorn

  • Is there an iconv with //TRANSLIT equivalent in java?

    - by Keith
    Is there a way to achieve transliteration of characters between charsets in java? something similar to the unix command (or similar php function): iconv -f UTF-8 -t ASCII//TRANSLIT < some_doc.txt > new_doc.txt preferably operating on strings, not having anything to do with files I know you can can change encodings with the String constructor, but that doesn't handle transliteration of characters that aren't in the resulting charset.

  • GWT Dynamic loading using GWT.create() with String literals instead of Class literals

    - by Sathish
    GWT.create() is the reflection equivalent in GWT, But it take only class literals, not fully qualified String for the Class name. How do i dynamically create classes with Strings using GWT.create()? Its not possible according to many GWT forum posts but how is it being done in frameworks like Rocket-GWT (http://code.google.com/p/rocket-gwt/wiki/Ioc) and Gwittir (http://code.google.com/p/gwittir/wiki/Introspection)

  • Regex Not Matching Unicode

    - by cam
    How would I go about using Regex to match Unicode strings? I'm loading in a couple keywords from a text file and using them with Regex on another file. The keywords both contain unicode (such á, etc). I'm not sure where the problem is. Is there some option I have to set?

  • Why Is ToString() Rounding My Double Value?

    - by user163757
    How do I prevent my double value from being rounded when converting to a string? I have tried both Convert.ToString and ToString() with the same result. For example my double may look something like 77.987654321, and the two strings conversions convert to to 77.98765. I need to keep the precision of the value as is.

  • SIMPLE OpenSSL RSA Encryption in C/C++ is causing me headaches

    - by Josh
    Hey guys, I'm having some trouble figuring out how to do this. Basically I just want a client and server to be able to send each other encrypted messages. This is going to be incredibly insecure because I'm trying to figure this all out so I might as well start at the ground floor. So far I've got all the keys working but encryption/decryption is giving me hell. I'll start by saying I am using C++ but most of these functions require C strings so whatever I'm doing may be causing problems. Note that on the client side I receive the following error in regards to decryption. error:04065072:rsa routines:RSA_EAY_PRIVATE_DECRYPT:padding check failed I don't really understand how padding works so I don't know how to fix it. Anywho here are the relevant variables on each side followed by the code. Client: RSA *myKey; // Loaded with private key // The below will hold the decrypted message unsigned char* decrypted = (unsigned char*) malloc(RSA_size(myKey)); /* The below holds the encrypted string received over the network. Originally held in a C-string but C strings never work for me and scare me so I put it in a C++ string */ string encrypted; // The reinterpret_cast line was to get rid of an error message. // Maybe the cause of one of my problems? if(RSA_private_decrypt(sizeof(encrypted.c_str()), reinterpret_cast<const unsigned char*>(encrypted.c_str()), decrypted, myKey, RSA_PKCS1_OAEP_PADDING)==-1) { cout << "Private decryption failed" << endl; ERR_error_string(ERR_peek_last_error(), errBuf); printf("Error: %s\n", errBuf); free(decrypted); exit(1); } Server: RSA *pkey; // Holds the client's public key string key; // Holds a session key I want to encrypt and send //The below will hold the encrypted message unsigned char *encrypted = (unsigned char*)malloc(RSA_size(pkey)); // The reinterpret_cast line was to get rid of an error message. // Maybe the cause of one of my problems? if(RSA_public_encrypt(sizeof(key.c_str()), reinterpret_cast<const unsigned char*>(key.c_str()), encrypted, pkey, RSA_PKCS1_OAEP_PADDING)==-1) { cout << "Public encryption failed" << endl; ERR_error_string(ERR_peek_last_error(), errBuf); printf("Error: %s\n", errBuf); free(encrypted); exit(1); } Let me once again state, in case I didn't before, that I know my code sucks but I'm just trying to establish a framework for understanding this. I'm sorry if this offends you veteran coders. Thanks in advance for any help you guys can provide!

  • How are hash functions like MD5 unique?

    - by Aly
    Im aware that MD5 has had some collisions but this is more of a high level question about hashing functions. If MD5 hashes any arbitrary string into a 32-digit hex value, then according to the Pigeonhole Principle surely this can not be unique as there are more unique arbitrary strings than there are unique 32-digit hex values

  • python mysqldb string formatting

    - by Daniel
    How do I do this correctly: I want to do a query like this: query = """SELECT * FROM sometable order by %s %s limit %s, %s;""" conn = app_globals.pool.connection() cur = conn.cursor() cur.execute(query, (sortname, sortorder, limit1, limit2) ) results = cur.fetchall() All works fine but the order by %s %s is not putting the strings in correctly. It is putting the two substitutions in with quotes around them. So it ends up like: ORDER BY 'somecol' 'DESC' Which is wrong should be: ORDER BY somecol DESC Any help greatly appreciated!

  • In Objective C, what's the best way to extract multiple substrings of text around multiple patterns?

    - by Matt
    For one NSString, I have N pattern strings. I'd like to extract substrings "around" the pattern matches. So, if i have "the quick brown fox jumped over the lazy dog" and my patterns are "brown" and "lazy" i would like to get "quick brown fox" and "the lazy dog." However, the substrings don't necessarily need to be delimited by whitespace. I have a hunch that there's a very easy solution to this, but I admit a disturbing lack of knowledge of Objective C string functions.

  • web.config overrides app.config...why?

    - by vikp
    Hi, I have to DLLs: one with a web.config, another one with app.config I moved the connection strings from web.config to app.config so that it can be used by other DLLs. Now, when I call ConfigurationManager.GetSection("SomeSection") , the application looks for a web.config, when it should be looking for the app.config. It doesn't make sense why it does it because web.config is in a separate DLL. Can anybody explain this please?

  • SQL: convert tokens in a string or elements of an array into rows of a table

    - by slowpoison
    Is there a simple way in SQL to convert a string or an array to rows of a table? For example, let's stay the string is 'a,b,c,d,e,f,g'. I'd prefer an SQL statement that takes that string, splits it at commas and inserts the resulting strings into a table. In PostgreSQL I can use regexp_split_to_array() and split the string into an array. So, if you know a way to insert an array's elements as rows into a table, that would work too.

  • Classic ASP vs. ASP.NET encryption options

    - by harrije
    I'm working on a web site where the new pages are ASP.NET and the legacy pages are Classic ASP. Being new to development in the Windows env, I've been studying the latest technology, i.e. .NET and I become like a deer in headlights when ever legacy issues come up regarding COM objects. Security on the website is an abomination, but I've easily encrypted the connectionStrings in the web.config file per http://www.4guysfromrolla.com/articles/021506-1.aspx based on DPAPI machine mode. I understand this approach is not the most secure, but it's better than nothing which is what it was for the ASP.NET pages. Now, I question how to do similar encryption for the connection strings used by the Classic ASP pages. A complicating factor is that the web sited is hosted where I do not have admin permissions or even command line access, just FTP. Moreover I want to avoid managing the key. My research has found: DPAPI with COM interop. Seems like this should already be available, but the only thing I could find discussing this is CyptoUtility (see http://msdn.microsoft.com/en-us/magazine/cc163884.aspx) which is not installed on the hosting server. There are plenty of other third party COM objects, e.g. Crypto from Dalun Software http://www.dalun.com, but these aren't on the hosted server either, and they look to me to require you to do some kind of key management. There is CAPICOM on the hosted server, but M$ has deprecated it and many report it is not the easiest to use. It is not clear to me whether I can avoid key management with CAPICOM similar to using DPAPI for ASP.NET. If anyone happens to know, please clue me in. I could write an web service in ASP.NET and have the classic ASP pages use it to get the decrypted connection strings and then store those in an application variable. I would not need to use SSL since I could use localhost and nothing would be sent over the internet. In the simpliest form I could implement what someone termed a poor man's version based on a simple XML stream, however, I really was looking to avoid any development since I find it hard to believe there is not a simple solution for Classic ASP like there is for ASP.NET. Maybe I'm missing some options... Recommendations are requested...

  • How-to index arrays (tags) in CouchDB using couchdb-lucene

    - by Lucas
    The setup: I have a project that is using CouchDB. The documents will have a field called "tags". This "tags" field is an array of strings (e.g., "tags":["tag1","tag2","etc"]). I am using couchdb-lucene as my search provider. The question: What function can be used to get couchdb-lucene to index the elements of "tags"? If you have an idea but no test environment, type it out, I'll try it and give the result here.

    I am trying to populate a NSPopUpButtonCell with a list of strings. In -(init), I populate an NSArray with the values I want in the PopUp Button. How do I connect this to the NSArrayController I added in IB? Does my app delegate need an IBOutlet NSArrayController to connect to or is there a way to bind it? Also, when I bind the NSArrayController to the NSPopUpButtonCell, do which Content do I bind it to? Content or Content Values? jorj

  • SHA-1 and Unicode

    - by Andrew
    Hi everyone, Is behavior of SHA-1 algorithm defined for Unicode strings? I do realize that SHA-1 itself does not care about the content of the string, however, it seems to me that in order to pass standard tests for SHA-1, the input string should be encoded with UTF-8.

  • Regex one-to-one mapping pattern replace

    - by polygenelubricants
    How would you use regex to write a function that replaces all lowercase letters with uppercase and vice versa? Note: this is NOT a homework question. See also my previous explorations of regex: Regex split into overlapping strings (Alan Moore's answer is especially instructive) Can you use zero-width matching regex in String split? (my solution exploits a known Java regex bug with regards to non-obvious length lookbehind!)
