• Java escape HTML - string replace slow?

  - by cpf

  Hi StackOverflow, I have a Java application that makes heavy use of a large file, to read, process and give through to SolrEmbeddedServer (http://lucene.apache.org/solr/). One of the functions does basic HTML escaping: private String htmlEscape(String input) { return input.replace("&", "&amp;").replace(">", "&gt;").replace("<", "&lt;") .replace("'", "&apos;").replaceAll("\"", "&quot;"); } While profiling the application, the program spends roughly 58% of the time in this function, a total of 47% in replace, and 11% in replaceAll. Now, is the Java replace that slow, or am I on the right path and should I consider the program efficient enough to have its bottleneck in Java and not in my code? (Or am I replacing wrong?) Thanks in advance!

• List<string> doesn't update the UI when change occurs [WPF]

  - by Hard Turner

• Sphinx: change column set for searching in runtime

  - by Fedyashev Nikita

  I use Ultrasphinx gem plugin as a wrapper for accessing Sphinx search daemon. My model declaration: class Foo < ActiveRecord::Base is_indexed :fields => ['content', 'private_notes', 'user_id'] Client code: filters = {} if type == "private" # search only in `content` column filters['user_id'] = current_user.id else # search in `content` and `private_notes` columns end results = Ultrasphinx::Search.new(:query => params[:query], :per_page => 20, :page => params[:page] || 1, :filters => filters) The problem I have now with Ultrasphinx gem(or Sphinx, in general?) is that it does not allow me to change set of fields where to look for matches IN RUNTIME How can I solve this problem?

• .NET: efficient way to produce a string from a Dictionary<K,V> ?

  - by Cheeso

  Suppose I have a Dictionary<String,String>, and I want to produce a string representation of it. The "stone tools" way of doing it would be: private static string DictionaryToString(Dictionary<String,String> hash) { var list = new List<String> (); foreach (var kvp in hash) { list.Add(kvp.Key + ":" + kvp.Value); } var result = String.Join(", ", list.ToArray()); return result; } Is there an efficient way to do this in C# using existing extension methods? I know about the ConvertAll() and ForEach() methods on List, that can be used to eliminate foreach loops. Is there a similar method I can use on Dictionary to iterate through the items and accomplish what I want?

• Double Inner Join generates unexpected error

  - by Itamar Marom

  In my database I have three tables: Users: UserID (Auto Numbering), UserName, UserPassword and a few other unimportant fields. PrivateMessages: MessageID (Auto Numbering), SenderID and a few other fields defining the message content. MessageStatus: MessageID, ReceiverID, MessageWasRead (Boolean) What I need is a query to which I input a user's id and I get all the private messages he has received. In addition, I also need to receive each message's sender UserName. For this I wrote the following query: SELECT Users.*, PrivateMessages.*, MessageStatus.* FROM PrivateMessages INNER JOIN Users ON PrivateMessages.SenderID = Users.UserID INNER JOIN MessageStatus ON PrivateMessages.MessageID = MessageStatus.MessageID WHERE MessageStatus.ReceiverID=[@userid]; But for some reason when I try saving it in my Access database, I get the following error (translated to English by me, since my office is in a different language): Syntax error (missing operator) at expression: "PrivateMessages.SenderID = Users.UserID INNER JOIN MessageStatus ON PrivateMessages.MessageID = MessageStatus.MessageI". Any ideas what could cause this? Thanks.

• C# - implementing GetEnumerator() for a collection inherited from List<string>

  - by Vojtech

  Hi, I am trying to implement FilePathCollection. Its items would be simple file names (without a path - such as "image.jpg"). Once the collection is used via foreach cycle, it should return the full path created by concatenating with "baseDirectory". How can I do that? public class FilePathCollection : List<string> { string baseDirectory; public FileCollection(string baseDirectory) { this.baseDirectory = baseDirectory; } new public System.Collections.IEnumerator GetEnumerator() { foreach (string value in this._list) //this does not work because _list is private yield return baseDirectory + value; } } Thanks in advance! :-)

• hiding inner class implementation using namespace

  - by Abruzzo Forte e Gentile

  Hi all I am developing a library and a would like to provide my users a public interface separate from the real implementatino that is hidden in a namespace. This way, I could change only the class HiddenQueue without changing myQueue that will be exposed to users only. If I put the C++ code of HiddenQueue in the myQueue.cpp file the compiler complains saying _innerQueue has incomplete type. I thought that the linker was able to resolve this. What I am doing wrong here? Thanks Afg // myQueue.h namespace inner{ class HiddenQueue; }; class myQueue{ public: myQueue(); ); private: inner::HiddenQueue _innerQueue; }; /////////////////////////// // myQueue.cpp namespace inner{ class HiddenQueue{}; };

• Launch x64 Windows application in C# while the project is set to x86

  - by daydr3am3r

  Hi all I'm trying to launch the osk.exe and I keep getting "Could not start osk" message. The problem is that my project is set to x86 (i'm using a ms access database). If I switch to x64 or Any CPU everything works fine but the database will no longer work. I tried this using System.Diagnostics; private void btnOSK_Click(object sender, EventArgs e) { Process.Start("osk.exe"); Process.Start(@"C:\windows\system32\osk.exe"); } I also tried to run SysWOWW\osk but this also didn't work. Besides my application should run on both x86 and x64 machines. Is there any way to bypass this? It's really frustrating.

• Are protected constructors considered good practice?

  - by Álvaro G. Vicario

  I'm writing some little helper classes to handle trees. Basically, I have a node and a special root node that represents the tree. I want to keep it generic and simple. This is part of the code: <?php class Tree extends TreeNode{ public function addById($node_id, $parent_id, $generic_content){ if( $parent = $this->findNodeById($parent_id) ){ $parent->addChildById($node_id, $generic_content); } } } class TreeNode{ public function __construct($node_id, $parent_id, $generic_content){ // ... } protected function addChildById($node_id, $generic_content){ $this->children[] = new TreeNode($this->node_id, $node_id, $generic_content); } } $Categories = new Tree; $Categories->addById(1, NULL, $foo); $Categories->addById(2, NULL, $bar); $Categories->addById(3, 1, $gee); ?> My questions: Is it sensible to force TreeNode instances to be created through TreeNode::addById()? If it's so, would it be good practise to declare TreeNode::__construct() as private/protected?

• .NET connecting to oracle problems with the connectionstring

  - by Oxymoron

  At the moment I'm trying to make a connection to a local server. Connecting via, say, TOAD works fine. When I try to connect using .NET I get ora-12154. Which puzzles me, since I'm using the connectionstring from my TNSNAMES.ora file: XE = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = myPC)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = XE) ) ) As follows: private string connectionString = "Data Source=(DESCRIPTION =" +" (ADDRESS_LIST=(ADDRESS = (PROTOCOL = TCP)(HOST = myPC)(PORT = 1521)))" +" (CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = XE));" +"User Id=sys;Password=zsxyzabc;"; Any ideas?

• C# Generics Casting

  - by Nippysaurus

  Visual sutdio 2008 has the ability to automatically create unit test stubs. I have used this to create some basic unit tests, but I am confused by something: private class bla : BaseStoreItem { // } /// <summary> ///A test for StoreData ///</summary> public void StoreDataTestHelper<T>() where T : BaseStoreItem { FileStore<T> target = new FileStore<T>(); // TODO: Initialize to an appropriate value BaseStoreItem data = new bla(); target.StoreData(data); } [TestMethod()] public void StoreDataTest() { //Assert.Inconclusive("No appropriate type parameter is found to satisfies the type constraint(s) of T. " + // "Please call StoreDataTestHelper<T>() with appropriate type parameters."); StoreDataTestHelper<bla>(); } Why do I get "Error: Cannot convert type 'StorageUnitTests.FileStoreTest.bla' to 'T'" when T is type "bla"? I know "bla" is not a good function name, but its just an example.

• "Dynamic" localized display of custom DateTimePicker format

  - by S.C. Madsen

  I have a Winform application with 2 DateTimePicker's on it, initialized as follows: private void InitializeComponent() { ... this._StartDate.Format = System.Windows.Forms.DateTimePickerFormat.Short; .... this._StartTime.CustomFormat = System.Globalization.DateTimeFormatInfo.CurrentInfo.ShortTimePattern; this._StartTime.Format = System.Windows.Forms.DateTimePickerFormat.Custom; ... } My question is: When I pick a new region from "Regional and Language Options" in the Control Panel, the _StartDate display is updated to reflect the new regional settings, but the _StartTime is not. Why?

• C++: retrieve map values and insert into second map

  - by donalmg

  Hi, I have one map within one header file class: class One { // code typedef map<string, int> MapStrToInt inline MapStrToInt& GetDetails(unsigned long index) { return pData[index]; } // populate pData.... private: MapStrToInt *pData; }; And a second class which implements another map and wants to get the first 10 details from the class One's map. class Two { // code One::MapStrToInt pDataTen; int function1() { for (int i =0; i < 10; i ++) { One::MapStrToInt * pMap = &(One::GetDetails(i)); pDataTen.insert(pair<string, int>(pMap->first,pMap->second)); } } When I compile this, it states that pMap: has no member named 'first' has no member named 'second' Any suggestions? Thanks..

• In C#: How to declare a generic Dictionary with a type as key and an enumeration of that type as val

  - by Marcel

  Hi all, I want to declare a dictionary that stores typed IEnumerable's of a specific type, with that exact type as key, like so: (Edited to follow johny g's comment) private IDictionary<Type, IEnumerable<T>> _dataOfType where T: BaseClass; //does not compile! The concrete classes I want to store, all derive from BaseClass, therefore the idea to use it as constraint. The compiler complains that it expects a semicolon after the member name. If it would work, I would expect this would make the later retrieval from the dictionary simple like: IEnumerable<ConcreteData> concreteData; _sitesOfType.TryGetValue(typeof(ConcreteType), out concreteData); How to define such a dictionary?

• Problematic comboBox Windows Forms

  - by zaidwaqi

  Hi, I use VS2008 C# + Windows Forms. I can't understand why comboBox does not behave the way it should. In Design mode, I added a comboBox to my form, and edit Items to add "A" and "B". Double-clicking brings me to SelectedIndexChanged event, which I edit to display the selected text with MessageBox. private void comboBoxImageSet_SelectedIndexChanged(object sender, EventArgs e) { MessageBox.Show(comboBoxImageSet.SelectedText); } When I run, and select "A" or "B" in the comboBox, the MessageBox appears, but nothing is written. Why? Thanks.

• What is the benefits and drawbacks of using header files?

  - by vodkhang

  I had some experience on programming languages like Java, C#, Scala as well as some lower level programming language like C, C++, Objective - C. My observation is that low level languages separate out header files and implementation files while other higher level programming language never separate it out. They use some identifiers like public, private, protected to do the jobs of header files. I saw one benefit of using header file (in some book like Code Complete), they talk about that using header files, people can never look at our implementation file and it helps with encapsulation. A drawback is that it creates too many files for me. Sometimes, it looks like verbose. It is just my thought and I don't know if there are any other benefits and drawbacks that people ever see and work with header file This question may not relate directly to programming but I think that if I can understand better about programming to interface, design software.

  Hello, I am using VS 2008 C# Windows Application. I have this DLL Import I am trying to use. [DllImport("Mapi32.dll", PreserveSig = true)] private static extern void WrapCompressedRTFStream( [MarshalAs(UnmanagedType.Interface)] UCOMIStream lpCompressedRTFStream, uint ulflags, [MarshalAs(UnmanagedType.Interface)] out UCOMIStream lpUncompressedRTFStream ); public const uint MAPI_MODIFY = 0x00000001; public const uint STORE_UNCOMPRESSED_RTF = 0x00008000; I have a compressed string that is in CompressedRFTFormat. How do I pass the string into the WrapCompressedRTFStream? I do not understand what the method is expecting. I am trying to use it on a button.

• PHP: Safe way to store decryptable passwords

  - by Jammer

  I'm making an application in PHP and there is a requirement that it must be possible to decrypt the passwords in order to avoid problems in the future with switching user database to different system. What encryption/decryption algorithm would you suggest? Is it good idea to just store the encrypted value and then compare the future authentication attempts to that value? Are the passwords still as safe as MD5/SHA1 when the private key is not available to the attacker (Hidden in USB drive for example)? I should still use salting, right? What encryption libraries should I use for PHP?

• Create an seo and web accessibility analyzer

  - by rebellion

  I'm thinking of making a little web tool for analyzing the search engine optimization and web accessiblity of a whole website. First of all, this is just a private tool for now. Crawling a whole website takes up alot of resources and time. I've found out that wget is the best option for downloading the markup for a whole site. I plan on using PHP/MySQL (maybe even CodeIgniter), but I'm not quite sure if that's the right way to do it. There's always someone who recommends Python, Ruby or Perl. I only know PHP and a little bit Rails. I've also found a great HTML DOM parser class in PHP on SourceForge. But, the thing is, I need some feedback on what I should and should not do. Everything from how I should make the crawl process to what I should be checking for in regards to SEO and WCAG. So, what comes to your mind when you hear this?

• Where to store frequently used functions in a OOP correct way

  - by Stefan Kuijers

  I'm working on a project which I want to build up OO. Now I came with a function that checks or a value is valid. private function valid(value:*, acceptedValues:Array):Boolean { for(var i:uint = 0; i < acceptedValues.length; i++) { if (value == acceptedValues[i]) { return true; } } return false; } As you can see, the function is very general and will be accessed across different classes. Now my question is; where do I store it in a OO correct way? Thanks in advance!

• Generic TypeIdenitifier convertion.How?

  - by John

  How do I convert the TypeIdenitifier to a class type? I need to use implicit convertion. type TMyChildArray<T>=class(TMyArray<T>) private FData:Array of T; procedure AddEnd(); end; TTypeIdenitifierParentClass=class(TAnotherParentClass) protected TestField:Cardinal; end; procedure TMyChildArray<T>.AddEnd(); var elem:T; begin for elem in Fdata do TTypeIdenitifierParentClass(elem).TestField:=0; end; I get "Invalid typecast" on the implicit convertion "TTypeIdenitifierParentClass(elem).TestField:=0;". The principle I want to use is that the TypeIdenitifier will represent a class that descends from TTypeIdenitifierParentClass.There are many class types,but all of them descend that class. How do I do this?

• Would you make this method Static or not?

  - by Adam Drummond

  During a code review I presented a method quickly to the team that I had made static and one person agreed that there was no reason for it to not be static and a person disagreed saying that he would not make it static because it wasn't necessary and just to be on the safe side for future modifications and testing. So I did quite a bit of research and obviously it's a specialized case but I would like to know what you would do in this situation and why? (Its basically a helper method I call from a few different methods, a very low traffic page. More for my knowledge and learning on Static.) private IEnumerable<Category> GetCategoryByID(int id, Context context) { var categoryQuery = from selectAllProc in context.SelectAll_sp() where selectAllProc.CategoryID == id select selectAllProc; return categoryQuery; }

• How to find the right object in a Rails controller based on two variables?

  - by sscirrus

  Hi everyone, I have a three-table system: Companies, Customers, and Matches. The matches include, for example, private notes that each party makes about the other and some options they can set regarding the other. I have two sets of views centered around Companies and Customers for each party to look at the other and modify their notes and settings. # Customers Controller def show @customer = Customer.find(params[:customer]) @matchings = @candidate.matchings.find... @company = Company.find(params[:company]) end Obviously the @matchings is incomplete. Given that @matchings has fields customer_id and company_id, how do I find the right matching record? Thank you!
