  • Access Codeigniter database functions from file

    - by Manny Calavera
    Hello. I am using a SWFupload script and I can't make a request from flash with mod_rewrite, I don't know why... I just need to point the Flash request to that file directly. This file runs an upload script that works ok but now I need to save some info to the database and I would like to know what should I write to have access from that file that is not called from the controller and does not extend the model in order to run a mysql query. Thanks.

  • static const C++ class member initialized gives a duplicate symbol error when linking

    - by Petruza
    I have a class which has a static const array, it has to be initialized outside the class: class foo{ static const int array[3]; }; const int foo::array[3] = { 1, 2, 3 }; But then I get a duplicate symbol foo::array in foo.o and main.o foo.o hold the foo class, and main.o holds main() and uses instances of foo. How can I share this static const array between all instances of foo? I mean, that's the idea of a static member.

  • xml to xsd to c# class - C# 3.0, .net 3.5

    - by uno
    Following this articlelink text one of the comments from 'zanoni' said he did it this way Using .NET 3.5: [XmlRoot] public class EmailConfiguration { [XmlElement] public string DataBoxID { get; set; } [XmlElement] public DefaultSendToAddressCollectionClass DefaultSendToAddressCollection { get; set; } } public class DefaultSendToAddressCollectionClass { [XmlElement] public string[] EmailAddress { get; set; } } How would I get my class to be as what he described? I ran the xsd tool and it is in the fashion as what shane posted in the above link [System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.3038")] [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)] [System.Xml.Serialization.XmlRootAttribute(Namespace="", IsNullable=false)] public partial class EmailConfiguration : object, System.ComponentModel.INotifyPropertyChanged { private string dataBoxIDField; private EmailConfigurationDefaultSendToAddressCollection[] defaultSendToAddressCollectionField; /// <remarks/> [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] public string DataBoxID { get { return this.dataBoxIDField; } set { this.dataBoxIDField = value; this.RaisePropertyChanged("DataBoxID"); } }

  • 2 Classes need each other declared C++

    - by Prodigga
    I have a "Game" class which holds all the games settings and manages the game. I have a "Grid" class which is the grid the game is played on. The "Game" class initializes a "Grid" object as one of its members (passing itself ("this") as one of the parameters for "Grid"s constructor).. The "Grid" object therefor needs to deal with a "Game*" pointer. To do this it needs to know what "Game" is; i need to declare it before "Grid". But "Game" uses "Grid"...so it also needs "Grid" declared before it. so confused on how to include headers/etc correctly here..

  • Inheritance and choose constructor from base class

    - by myle
    My question is rather simple, but I am stuck. How can I choose the desired constructor from base class? // node.h #ifndef NODE_H #define NODE_H #include <vector> // definition of an exception-class class WrongBoundsException { }; class Node { public: ...

  • How to append html to first occurance of string after selected element

  • C# How to create objects without class definitions?

    - by JL
    Is it possible to create objects at designtime without having to have hard coded class definitions, then populate properties with primitives or even strongly typed data types? This might sound confusing, so I will attempt to give you a use case scenario. Use case: You have an XML config file that could hold configuration values for connecting to various systems in an SOA application. In C# the XML file is read, but for each system the configuration properties are different (e.g: SQL might have a connection string, while SharePoint might need a username + password + domain + url, while yet an smtp server would need username + password + port + url) So instead of creating static classes as follows public class SharePointConfiguration or public class SQLConfiguration, then have each class with custom properties (this is cumbersome) or using a 1990's method, an arrayList or some named collection Is there not a more preferred way to achieve this? Taking advantage of new language features, that can still offer design time intellisense, which would make the code easier to maintain and less prone to error. Thanks

  • Using member variables inherited from a templated base class (C++)

    - by Aaron Becker
    I'm trying to use member variables of a templated base class in a derived class, as in this example: template <class dtype> struct A { int x; }; template <class dtype> struct B : public A<dtype> { void test() { int id1 = this->x; // always works int id2 = A<dtype>::x; // always works int id3 = B::x; // always works int id4 = x; // fails in gcc & clang, works in icc and xlc } }; gcc and clang are both very picky about using this variable, and require either an explicit scope or the explicit use of "this". With some other compilers (xlc and icc), things work as I would expect. Is this a case of xlc and icc allowing code that's not standard, or a bug in gcc and clang?

  • friend declaration block an external function access to the private section of a class

    - by MiP
    I'm trying to force function caller from a specific class. For example this code bellow demonstrate my problem. I want to make 'use' function would be called only from class A. I'm using a global namespace all over the project. a.h #include "b.h" namespace GLOBAL{ class A{ public: void doSomething(B); } } a.cpp #include "a.h" using namespace GLOBAL; void A::doSomething(B b){ b.use(); } b.h namespace GLOBAL{ class B{ public: friend void GLOBAL::A::doSomething(B); private: void use(); } Compiler says: ‘GLOBAL::A’ has not been declared ‘void GLOBAL::B::use()’ is private Can anyone help here ? Thanks a lot, Mike.

  • Java: Make a method abstract for each extending class

    - by Martijn Courteaux
    Hi, Is there any keyword or design pattern for doing this? public abstract class Root { public abstract void foo(); } public abstract class SubClass extends Root { public void foo() { // Do something } } public class SubberClass extends SubClass { // Here is it not necessary to override foo() // So is there a way to make this necessary? // A way to obligate the developer make again the override } Thanks

  • Anonymous functions in C#

    - by Maxim Gershkovich
    The following syntax is valid VB.NET code Dim myCollection As New List(Of Stock) myCollection.Add(New Stock(Guid.NewGuid, "Item1")) myCollection.Add(New Stock(Guid.NewGuid, "Item2")) Dim res As List(Of Stock) = myCollection.FindAll(Function(stock As Stock) As Boolean If stock.Description = "Item2" Then Return True End If Return False End Function) How can I accomplish the same thing in C#? I have tried... myCollection.FindAll(bool delegate(Stock stock) { if (blah blah) { } }); But it appears I have somehow structured it incorrectly as I get the following error. "Error 1 Invalid expression term 'bool'"

  • preg_replace only replaces first occurrence then skips to next line

    - by Dom
    Got a problem where preg_replace only replaces the first match it finds then jumps to the next line and skips the remaining parts on the same line that I also want to be replaced. What I do is that I read a CSS file that sometimes have multiple "url(media/pic.gif)" on a row and replace "media/pic.gif" (the file is then saved as a copy with the replaced parts). The content of the CSS file is put into the variable $resource_content: $resource_content = preg_replace('#(url\((\'|")?)(.*)((\'|")?\))#i', '${1}'.url::base(FALSE).'${3}'.'${4}', $resource_content); Does anyone know a solution for why it only replaces the first match per line?

  • Making your own "int" or "string" class

    - by amerninja13
    I disassembled the .NET 'System' DLL and looked at the source code for the variable classes (string, int, byte, etc.) to see if I could figure out how to make a class that could take on a value. I noticed that the "Int32" class inherits the following: IComparable, IFormattable, IConvertible, IComparable, IEquatable. The String and Int32 classes are not inheritable, and I can't figure out what in these inherited interfaces allows the classes to hold a value. What I would want is something like this: public class MyVariable : //inherits here { //Code in here that allows it to get/set the value } public static class Main(string[] args) { MyVariable a = "This is my own custom variable!"; MyVariable b = 2976; if(a == "Hello") { } if(b = 10) { } Console.WriteLine(a.ToString()); Console.WriteLine(a.ToString()); }

  • Instanciate a class with a given id in ExtJS

    - by Miller
    Hello, I would like to know if it is possible to instanciate a class by its id . For example we have a class extending Ext.grid.GridPanel with an id property, is it possible to instanciate the class just knowing his id (which is the component id in this case) ?

  • Question about variable definitions in functions.

    - by Kaan Tekelioglu
    Hi. #include <stdio.h> main() { int a; for(a=1; a<=4 && printf("%d ",a); a++) { int a; static int b=a; printf("%d ",(a++)-b); } getchar(); getchar(); } In this code, the printout is 1 0 2 1 3 2 4 3. I understand why the int a; part works differently then the int a which was defined outside the for function, and why static int b; is only defined once with the primary value of a ; but why does the (a++) part in printf affect proceeding values of a? Don't we redefine int a; each time the for function runs? Thanks in advance.

  • How do I override methods of nested types?

    - by Mason Wheeler
    I've got a custom TObjectList descendant in Delphi 2009, and I'd like to play with its enumerator a bit and add some filtering functionality to the MoveNext method, to cause it to skip certain objects. MoveNext is called by DoMoveNext, which is a virtual method, so this shouldn't be difficult to override... except for one thing. The TEnumerator for TObjectList isn't its own class; it's declared as a nested type within the TObjectList declaration. Is there any simple way to override TEnumerator.DoMoveNext in my descendant class, or do I have to reimplement the whole TEnumerator? It's not a very big class, but I'd prefer to keep redundancies to a minimum if I can...

  • packing fields of a class into a byte array in c#

    - by alex
    Hi all: I am trying to create a fast way to convert c# classes into byte array. I thought of serializing the class directly to a byte array using an example I found: // Convert an object to a byte array private byte[] ObjectToByteArray(Object obj) { if(obj == null) return null; BinaryFormatter bf = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); bf.Serialize(ms, obj); return ms.ToArray(); } But the byte array I got contains some other information that are not related to the fields in the class. I guess it is also converting the Properties of the class. Is there a way to serialize only the fields of the class to a byte array? Thanks

  • C++ Changing a class in a dll where a pointer to that class is returned to other dlls...

    - by Patrick
    Hello, Horrible title I know, horrible question too. I'm working with a bit of software where a dll returns a ptr to an internal class. Other dlls (calling dlls) then use this pointer to call methods of that class directly: //dll 1 internalclass m_class; internalclass* getInternalObject() { return &m_class; } //dll 2 internalclass* classptr = getInternalObject(); classptr->method(); This smells pretty bad to me but it's what I've got... I want to add a new method to internalclass as one of the calling dlls needs additional functionality. I'm certain that all dlls that access this class will need to be rebuilt after the new method is included but I can't work out the logic of why. My thinking is it's something to do with the already compiled calling dll having the physical address of each function within internalclass in the other dll but I don't really understand it; is anyone here able to provide a concise explanation of how the dlls (new internal class dll, rebuilt calling dll and calling dll built with previous version of the internal class dll) would fit together? Thanks, Patrick

  • Interacting With Class Objects in Ruby

    - by michaelmichael
    How can I interact with objects I've created based on their given attributes in Ruby? To give some context, I'm parsing a text file that might have several hundred entries like the following: ASIN: B00137RNIQ -------------------------Status Info------------------------- Upload created: 2010-04-09 09:33:45 Upload state: Imported Upload state id: 3 I can parse the above with regular expressions and use the data to create new objects in a "Product" class: class Product attr_reader :asin, :creation_date, :upload_state, :upload_state_id def initialize(asin, creation_date, upload_state, upload_state_id) @asin = asin @creation_date = creation_date @upload_state = upload_state @upload_state_id = upload_state_id end end After parsing, the raw text from above will be stored in an object that look like this: [#<Product:0x00000101006ef8 @asin="B00137RNIQ", @creation_date="2010-04-09 09:33:45 ", @upload_state="Imported ", @upload_state_id="3">] How can I then interact with the newly created class objects? For example, how might I pull all the creation dates for objects with an upload_state_id of 3? I get the feeling I'm going to have to write class methods, but I'm a bit stuck on where to start.
