  • Python: override __init__ args in __new__

    - by EoghanM
    I have a __new__ method as follows: class MyClass(object): def __new__(cls, *args): new_args = [] args.sort() prev = args.pop(0) while args: next = args.pop(0) if prev.compare(next): prev = prev.combine(next) else: new_args.append(prev) prev = next if some_check(prev): return SomeOtherClass() new_args.append(prev) return super(MyClass, cls).__new__(cls, new_args) def __init__(self, *args): ... However, this fails with a deprecation warning: DeprecationWarning: object.__new__() takes no parameters SomeOtherClass can optionally get created as the args are processed, that's why they are being processed in __new__ and not in __init__ What is the best way to pass new_args to __init__? Otherwise, I'll have to duplicate the processing of args in __init__ (without some_check)

  • Can I add custom methods/attributes to built-in Python types?

    - by sfjedi
    For example—say I want to add a helloWorld() method to Python's dict type. Can I do this? JavaScript has a prototype object that behaves this way. Maybe it's bad design and I should subclass the dict object, but then it only works on the subclasses and I want it to work on any and all future dictionaries. Here's how it would go down in JavaScript: String.prototype.hello = function() { alert("Hello, " + this + "!"); } "Jed".hello() //alerts "Hello, Jed!" Here's a useful link with more examples— http://www.javascriptkit.com/javatutors/proto3.shtml

  • Please suggest some alternative to Drupal

    - by abovesun
    Drupal propose completely different approach in web development (comparing with RoR like frameworks) and it is extremely good from development speed perspective. For example, it is quite easy to clone 90% of stackoverflow functionality using Drupal. But it has several big drawbacks: it is f''cking slow (100-400 requests per page) db structure very complicated, need at least 2 tables for easy content (entity) type, CCK fields very easy generate tons of new db tables anti-object oriented, rather aspect-oriented bad "view" layer implementation, no strange forward layouts and so on. After all this items I can say I like Drupal, but I would like something same, but more elegant and more object oriented. Probably something like http://drupy.net/ - drupal emulation on the top of django. P.S. I wrote this question not for new holy word flame, just write if you know alternative that uses something similar approach.

  • PHP PDO: Fetching data as objects - properties assigned BEFORE __construct is called. Is this correc

    - by Erik
    The full question should be "Is this correct or is it some bug I can't count on?" I've been working with PDO more and in particular playing with fetching data directly into objects. While doing so I discovered this: If I fetch data directly into an object like this: $STH = $DBH->prepare('SELECT first_name, address from people WHERE 1'); $obj = $STH->fetchAll(PDO::FETCH_CLASS, 'person'); and have an object like this: class person { public $first_name; public $address; function __construct() { $this->first_name = $this->first_name . " is the name"; } } It shows me that the properties are being assigned before the __construct is being called -- because the names all have " is the name" appended. Is this some bug (in which case I can't/won't count on it) or is this The Way It Should Be. Because it's really quite a nice thing the way it works currently.

  • Virtual Function Implementation

    - by Gokul
    Hi, I have kept hearing this statement. Switch..Case is Evil for code maintenance, but it provides better performance(since compiler can inline stuffs etc..). Virtual functions are very good for code maintenance, but they incur a performance penalty of two pointer indirections. Say i have a base class with 2 subclasses(X and Y) and one virtual function, so there will be two virtual tables. The object has a pointer, based on which it will choose a virtual table. So for the compiler, it is more like switch( object's function ptr ) { case 0x....: X->call(); break; case 0x....: Y->call(); }; So why should virtual function cost more, if it can get implemented this way, as the compiler can do the same in-lining and other stuff here. Or explain me, why is it decided not to implement the virtual function execution in this way? Thanks, Gokul.

  • Sharepoint Site Administration

    - by Shrewd Demon
    Hey, I've got a SharePoint website running on my machine (which it shows me inside the Application Pool in the Inet Manager). Now this website has a different user credentials specified under the Identity section (properties). Also when I view the w3wp.exe in the task manager it shows that the site is running as a different user. The problem is that if I change the username and password of the existing user with mine, the site stops working. How do I run it under my account credentials. Please help. Thanks

  • ASP.NET 1.0 site error after upgrade to VS.NET 2010

    - by Keith
    Help. I installed VS.NET 2010 and now my existing ASP.NET MVC application won't run. I checked that the 1.0 version of System.Web.Mvc is still referenced but when I browse my application, I get an error like this: "Compiler Error Message: CS1579: foreach statement cannot operate on variables of type 'object' because 'object' does not contain a public definition for 'GetEnumerator'". My partial view has this declaration: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<ProductModel" %> //various import statements <div <% foreach (var category in Model.Categories) { % <span<%= category.Name %</span <span<%= category.Market%</span <% } % </div For what it's worth, the source view shows ViewUserControl in red and gives a tool tip reading "Cannot resolve symbol 'ViewUserControl'". My working code didn't change, the only delta is that I upgraded to VS.NET 2010 (which includes MVC 2.0); I'm sure something is not referenced correctly but I cannot figure out what's going on.

  • merging arrays of hashes

    - by Ben
    I have two arrays of hashes. Array1 => [{attribute_1 = A, attribute_2 = B}, {attribute_1 = A, attribute_2 = B}] Array2 => [{attribute_3 = C, attribute_2 = D}, {attribute_3 = C, attribute_4 = D}] Each hash in the array is holding attributes for an object. In the above example, there are two objects that I'm working with. There are two attributes in each array for each object How do I merge the two arrays? I am trying to get a single array (there is no way to get a single array from the start because I have to make two different API calls to get these attributes). DesiredArray => [{attribute_1 = A, attribute_2 = B, attribute_3 = C, attribute_2 = D}, {attribute_1 = A, attribute_2 = B, attribute_3 = C, attribute_2 = D}] I've tried a couple things, including the iteration methods and the merge method, but I've been unable to get the array I need.

  • Getting "Location" header from NSHTTPURLResponse

    - by aspcartman
    Can't get "Location" header from response at all. Wireshark says that i've got one: Location: http://*/index.html#0;sid=865a84f0212a3a35d8e9d5f68398e535 But NSHTTPURLResponse *hr = (NSHTTPURLResponse*)response; NSDictionary *dict = [hr allHeaderFields]; NSLog(@"HEADERS : %@",[dict description]); Produces this: HEADERS : { Connection = "keep-alive"; "Content-Encoding" = gzip; "Content-Type" = "text/html"; Date = "Thu, 25 Mar 2010 08:12:08 GMT"; "Last-Modified" = "Sat, 29 Nov 2008 15:50:54 GMT"; Server = "nginx/0.7.59"; "Transfer-Encoding" = Identity; } No location anywhere. How to get it? I need this "sid" thing.

  • Java: omitting a data member from the equals method.

    - by cchampion
    public class GamePiece { public GamePiece(char cLetter, int nPointValue) { m_cLetter=cLetter; m_nPointValue=nPointValue; m_nTurnPlaced=0; //has not been placed on game board yet. } public char GetLetter() {return m_cLetter;} public int GetPointValue() {return m_nPointValue;} public int GetTurnPlaced() {return m_nTurnPlaced;} public void SetTurnPlaced(int nTurnPlaced) { m_nTurnPlaced=nTurnPlaced; } @Override public boolean equals(Object obj) { /*NOTE to keep this shorter I omitted some of the null checking and instanceof stuff. */ GamePiece other = (GamePiece) obj; //not case sensitive, and I don`t think we want it to be here. if(m_cLetter != other.m_cLetter) { return false; } if(m_nPointValue != other.m_nPointValue) { return false; } /* NOTICE! m_nPointValue purposely omitted. It does not affect hashcode or equals */ return true; } @Override public int hashCode() { /* NOTICE! m_nPointValue purposely omitted. It should not affect hashcode or equals */ final int prime = 41; return prime * (prime + m_nPointValue + m_cLetter); } private char m_cLetter; private int m_nPointValue; private int m_nTurnPlaced;//turn which the game piece was placed on the game board. Does not affect equals or has code! } Consider the given piece of code. This object has been immutable until the introduction of the m_nTurnPlaced member (which can be modified by the SetTurnPlaced method, so now GamePiece becomes mutable). GamePiece is used in an ArrayList, I call contains and remove methods which both rely on the equals method to be implemented. My question is this, is it ok or common practice in Java for some members to not affect equals and hashcode? How will this affect its use in my ArrayList? What type of java Collections would it NOT be safe to use this object now that it is mutable? I've been told that you're not supposed to override equals on mutable objects because it causes some collections to behave "strangely" (I read that somewhere in the java documentation).

  • Confused with the Isolated Storage with Multiple Assemblies Access

    - by Peter Lee
    I googled and searched a lot, but I got no luck. I have a WindowsFormsApplication.exe and ConsoleApplication.exe. I want both of them to access to the same IsolatedStorage, is it possible? I tried using this in ConsoleApplication.exe: IsolatedStorageFile isoStore = IsolatedStorageFile.GetMachineStoreForApplication(); but I got: IsolatedStorageException: Unable to determine application identity of the caller. How can I fix this? Or can I use this way? P.S.: This is NOT a ClickOnce app.

  • Get All Users in an Active Directory Group

    I'm using the following code sample to get a list of all users in a specified AD group (in this case, all users in the "Domain Users" group). My listed code works great, with one exception: it won't return users who have their primary group set to "Domain Users". How can I get a list of all users in the group, including those who have it set as their primary group? Private Sub GetUsers() Dim groupSearcher As New DirectorySearcher Dim groupSearchRoot As New DirectoryEntry("LDAP://OU=Users,DC=domain,DC=com") With groupSearcher .SearchRoot = groupSearchRoot .Filter = "(&(ObjectClass=Group)(CN=Domain Users))" End With Dim members As Object members = groupSearcher.FindOne.GetDirectoryEntry.Invoke("Members", Nothing) For Each member As Object In CType(members, IEnumerable) Console.WriteLine(New DirectoryEntry(member).Name.Remove(0, 3)) Next End Sub

    Hi, I was looking for the the trick to resolve that error (google, stackoverflow.com etc) and every nothing works. I need to dinamically create an .aspx file via the asp.net application. What I've done to try fix it: 1) In the folder's Properties - Security, I've added IUSR_TONY and also IIS_IUSRS and allow them the Full control to the folder. Just to check if that will help. Nope, it won't. 2) in the IIS Manager, I tried to change the Application's Pool Defaults Identity (based on that) I checked all options, with no success I don't know what to do more to fix it. Any ideas ?

  • Which containers / graphics components to use in a simple Java Swing game?

    - by rize
    I'm creating a simple labyrinth game with Java + Swing. The game draws a randomized labyrinth on the screen, places a figure in the middle, and the player is then supposed to find the way out by moving the figure with arrow-keys. As for now, I'm using a plain background and drawing the walls of the labyrinth with Graphics.drawLine(). I have a custom picture of the figure in a .gif file, which I load as a BufferedImage object. However, I want the player to see only part of the labyrinth at a time, and the screen should follow the figure in the game, as the player moves around. I'm planning to do this by creating an Image object of the whole labyrinth when it is created, and then "cutting" a square around the current position of the figure and displaying this with Graphics.drawImage(). I'm new with Swing though, and I can't figure out how to draw the figure at different positions "above" the labyrinth without redrawing the whole thing. Which container/component should I use for the labyrinth and then for the figure to achieve this?

  • Doesn't get into Debug Mode

    When I Press F5 on my VS2005 to debug the application, it launches the web app window but it is coming out of debug mode. When I tried to trace the Error in the EventViewer, this was the error: Failed in Token.vb(GetToken). The token was not in memory and the identity of the authenticated IIS caller was not permitted. The session may have unexpectedly terminated. The specific error message included: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration. I don't have any httpModules section in my config file and the sessionState mode="InProc"...

  • AuthenticationType Negotiate vs NTLM

    - by Claudio Redi
    I have the same code base used on 2 different sites hosted on the same server (IIS 7.5). For some reason, when I check the Identity.AuthenticationType property on the code behind of an http handler I see NTLM for 1 site and Negotiate for the other. This is causing some problems and I need both of them to use NTLM. Could you help me to figure out why this difference? So far I see both IIS sites are configured on the same way but of course there is at least 1 difference that I couldn't detect. Thanks!

  • How can the javascript plugin architecture in raphael/jquery be done?

    - by TimDog
    I'm looking for a barebones javascript example that demonstrates how the javascript plugin architecture works with large javascript libraries (such as raphael or jquery). In either scenario, you build plugins by ensuring your custom plugin follows this pattern: jQuery.fn.pluginName -- so assume I have a library: myLibrary = (function() { //my fancy javascript code return function() { //my return object }; }); How would fn be incorporated into the above myLibrary object to ensure that he resulting plugin is callable? I instantiate myLibrary like so: var lib = new myLibrary(); And now I have included a reference to my plugin in my page: myLibrary.fn.simplePlugin = function() { //more fancy code } So finally, I can just call: lib.simplePlugin(); Basically, what magic is actually occuring when the .fn is used during the creation of the plugin?

  • Avoiding dispose of underlying stream

In the "real" object I have: StreamWriter createFile( string name ) { return new StreamWriter( Path.Combine( _outFolder, name ), false, Encoding.UTF8 ) ); } In the mock object I'd like to have: StreamWriter createFile( string name ) { var ms = new MemoryStream(); _files.Add( Path.Combine( _outFolder, name ), ms ); return new StreamWriter( ms, Encoding.UTF8 ) ); } where _files is a dictionary to store created files for later inspection. However, when the consumer closes the StreamWriter, it also disposes the MeamoryStream... :-( Any thoughts on how to pursue this?
