  • Parsing a simple XML from string in Cocoa?

    - by Nick Brooks
    I have a simple XML and I need to get the first 'id' from puid-list. I found lots of examples but none of them quite do that because of the namespace. How do get the id out as an NSString? <genpuid songs="1" xmlns:mip="http://musicip.com/ns/mip-1.0#"> <track file="/htdocs/test.mp3" puid="0c9f2f0e-e72a-c461-9b9a-e18e8964ca20"> <puid-list> <puid id="0c9f2f0e-e72a-c461-9b9a-e18e8964ca20"/> </puid-list> </track> </genpuid>

  • ASP.Net Architecture Specific to Shared/Static functions

    - by Maxim Gershkovich
    Hello All, Could someone please advise in the context of a ASP.Net application is a shared/static function common to all users? If for example you have a function Public shared function GetStockByID(StockID as Guid) as Stock Is that function common to all current users of your application? Or is the shared function only specific to the current user and shared in the context of ONLY that current user? So more specifically my question is this, besides database concurrency issues such as table locking do I need to concern myself with threading issues in shared functions in an ASP.Net application? In my head; let’s say my application namespace is MyTestApplicationNamespace. Everytime a new user connects to my site a new instance of the MyTestApplicationNamespace is created and therefore all shared functions are common to that instance and user but NOT common across multiple users. Is this correct?

  • Is there an equivalent for the Zip function in Clojure Core or Contrib?

    - by John Kane
    In Clojure, I want to combine two lists to give a list of pairs, > (zip '(1 2 3) '(4 5 6)) ((1 4) (2 5) (3 6)) In Haskell or Ruby the function is called zip. Implementing it is not difficult, but I wanted to make sure I wasn't missing a function in Core or Contrib. There is a zip namespace in Core, but it is described as providing access to the Zipper functional technique, which does not appear to be what I am after. Is there an equivalent function for combining 2 or more lists, in this way, in Core? If there is not, is it because there is an idiomatic approach that renders the function unneeded?

    I am trying to modify a textBox found in the server Form using remoting from the client side. i have tried some solutions i found, but none of them work. the remoting part works propperly, the only thing that I am not able to figure out is this: this is what i have: client side: ... private void btn_b1_Click(object sender, EventArgs e) { ... myFunc.update(string s); ... } ... sharedLibs: public interface myInterf { void update(string s); } server side: here i have 2 classes in the same namespace class class1 : MarshalByRefObject, myInterf { public void update(string s) { //what do i write here to modify textBox1? } } public partial class class2 : Form { ... // here is the textBox i am trying to alter; }

  • Executing a dynamically bound function in Clojure

    - by Carl Smotricz
    I'd like to pre-store a bunch of function calls in a data structure and later evaluate/execute them from within another function. This works as planned for functions defined at namespace level with defn (even though the function definition comes after my creation of the data structure) but will not work with functions defined by let [name (fn or letfn inside the function. Here's my small self-contained example: (def todoA '(funcA)) (def todoB '(funcB)) (def todoC '(funcC)) (def todoD '(funcD)) ; unused (defn funcA [] (println "hello funcA!")) (declare funcB funcC) (defn runit [] (let [funcB (fn [] (println "hello funcB"))] (letfn [(funcC [] (println "hello funcC!"))] (funcA) (eval todoA) ; OK (funcB) ; OK (eval todoB) ; "Unable to resolve symbol: funcB in this context" at line 2 (funcC) ; OK (eval todoC) ; "Unable to resolve symbol: funcC in this context" at line 3 ))) Is there a simple fix I could undertake to get eval'd quoted calls to functions to work for functions defined inside another function?

  • Ruby on Rails: How do you do HTTP auth over multiple controllers?

    - by DerNalia
    So, Here are the relevant routes map.namespace "admin" do |admin| admin.root :controller => :site_prefs, :action => :index admin.resources :site_prefs admin.resources :link_pages admin.resources :menu_bars admin.resources :services admin.resources :users end And I have this for one controller: before_filter :authenticate protected def authenticate authenticate_or_request_with_http_basic do |username, password| username == "1234" && password == "1234" end end How do I set up my admin controllers to authenticate no matter what page within any of those controllers is navigated to, yet only have it authenticate once among all the admin controllers, and have the code all in one spot. Right now, the only I can think of to authenticate is to copy the auth code into each controller, and I hate having duplicate code... so.... yeah

  • Komodo IDE 6's slow autocomplete problems with Javascript

    - by skerit
    I've been trying out Komodo IDE 6 for the last few days. I've always liked Komodo but I'm starting to get annoyed by something: The autocomplete is way too slow/buggy. Certain variables just won't give any autocomplete tips. Sometimes you have to backspace the dot and try over and over again. It also has a hard time giving autocomplete info for an object that has been created using a class in a namespace. Has anyone else had any problems with these things? Are there any better alternatives?

  • C# Dynamic Query Without A Database Model

    - by hitopp
    I have been searching the web for a solution to dynamic queries. I have found many different solutions (e.g. Linq to Sql, Dynamic Linq Expressions, Dynamic Query), but all of these solutions involve some sort of previous knowledge of the database (like a model in code). Maybe what I am asking is way off the deep end, but is there any possible way to dynamically query a database without a model? For example, a database has a Customers table with the following columns: CustomerID Name FavoriteColor I want to create a query as SELECT Name FROM Customers WHERE @0 = @1, where the two placeholders are populated dynamically. The resulting data does not tie to a model class and I would prefer to use some sort of framework to build the queries, not simple string concatenation. The System.Linq.Dynamic namespace came really close to fulfilling this request, but it uses a database model. I realize this is crazy, but I was just curious.

  • How do I draw a gradated boarder on a polygon using GDI+ via C#/WinForms?

    - by AndyJ
    Hi, I have polygons of various shapes and sizes. They have a solid fill and currently a solid border. I would like to give the polygons a gradient on their edge to soften them. So far I've tried using a Pen with a LinearGradientBrush and whilst the effect it produces is very interesting it's most defintly not what I want ;) I've looked through the System.Drawing.Drawing2D namespace but there didnt seem to be any other classes that would be applicable for this purpose. I've had a search around and the articles that i can find are mostly about creating boarders for rectangles, which are mush easier, or are irrelivent. So to summerise, does anyone have a way of drawing a gradient boarder on a polygon using GDI+?

  • Refactoring tools for namespaces and physical project structure

    - by simendsjo
    When I hack around, some code tend to get much bigger than originally planned. As this happens I usually introduce/collapse/merge namespaces, move files between them, move folders etc etc. Sometimes, if I don't have a clear picture of the end result, this is a real pain and really easy to just "skip". This leads the project deteriorate where classes belong elsewhere, strange namespaces, no folders/wrong folders etc. And then I usually cannot take it anymore and do a larger cleanup - which is usually not difficult, just very tedious and it feels nice to do everything at once, so I do a code freeze while finishing up. So my question is... Are there any tools to help refactoring the namespace/physical aspects of a project?

  • Exceptions in ASP.MVC

    - by George
    Hello guys, I'm here again with another question about MVC. Here is the deal. I have a simple table/class with an Id and a Name. Names suppossed to be unique, and are modeled like that in the DB. I created my controller and everything just works fine. But if I try to insert a name that already exists, an exception should be thrown. I'm just not finding what is the correct kind of exception and it's namespace. The error must be coming from the DB, so... Any ideas? Thanks

  • How is it possible the class inheritance in namespaces using Ruby on Rails 3?

    - by user502052
    In my RoR3 application I have a namespace called NS1 so that I have this filesystem structure: ROOT_RAILS/controllers/ ROOT_RAILS/controllers/application_controller.rb ROOT_RAILS/controllers/ns/ ROOT_RAILS/controllers/ns/ns_controller.rb ROOT_RAILS/controllers/ns/names_controller.rb ROOT_RAILS/controllers/ns/surnames_controller.rb I wuold like that 'ns_controller.rb' inherits from application controller, so in 'ns_controller.rb' file I have: class Ns::NsController < ApplicationController ... end Is this the right approach? Anyway if I have this situation... in 'application_controller.rb' class ApplicationController < ActionController::Base @profile = Profile.find(1) end in 'ns_controller.rb' class Ns::NsController < ApplicationController @name = @profile.name @surname = @profile.surname end ... '@name' and '@surname' variables are not set. Why?

  • best way to add route under resource in Laravel 4

    - by passingby
    I would like know if there is a better way to add additional route aside from the default of resource in Laravel 4. I have this code below which is no problem with regard to the functionality, it's just that it seems to be long: <?php Route::group(array('before' => 'auth'), function() { # API Route::group(array('prefix' => 'api'), function() { Route::resource('projects', 'ProjectsController'); Route::resource('projects.groups', 'GroupsController'); Route::post('/projects/{projects}/groups/{groups}/reorder', 'GroupsController@reorder'); }); }); If in Rails Rails.application.routes.draw do # API namespace :api, defaults: { format: 'json' } do scope module: :v1 do resources :projects do resources :groups do member do post :reorder end end end end end end

  • Assigning a variable of a struct that contains an instance of a class to another variable

    - by xport
    In my understanding, assigning a variable of a struct to another variable of the same type will make a copy. But this rule seems broken as shown on the following figure. Could you explain why this happened? using System; namespace ReferenceInValue { class Inner { public int data; public Inner(int data) { this.data = data; } } struct Outer { public Inner inner; public Outer(int data) { this.inner = new Inner(data); } } class Program { static void Main(string[] args) { Outer p1 = new Outer(1); Outer p2 = p1; Console.WriteLine("p1:{0}, p2:{1}", p1.inner.data, p2.inner.data); p1.inner.data = 2; Console.WriteLine("p1:{0}, p2:{1}", p1.inner.data, p2.inner.data); p2.inner.data = 3; Console.WriteLine("p1:{0}, p2:{1}", p1.inner.data, p2.inner.data); Console.ReadKey(); } } }

  • C# public partial struct methods for more System.Windows.Media.Color

    - by dr d b karron
    How can I put in additional methods for manipulating color ? Best would be to overload the struct System.Windows.Media.Color. It is NOT a class (in c#). Now i'm tinkering with putting (in the same file for testing or must i put it in a different file) an namespace (Silverlight Application36 or System.Windows.Media ?) and a partial struct Color Normalize (double R, ...). I should see MyColor.Normalize() start being recognized by intellisense ? I'm not. I'm looking to put in a suite of overloaded color manipulations using floating and double numbers instead of unsigned byte integers. Any hints while I wack at it ? Cheers! dr.K

  • SQL CLR and nullable datetime parameter

    - by toluca70
    I'm trying to write a SQLCLR function that takes a DateTime2 as input and returns another DateTime2. Based on this post I altered the parameter to be the C# type DateTime giving me the level of precision I require. However because the input can be null I would like it to be DateTime?; the return type as well. using System; using Microsoft.SqlServer.Server; namespace SqlServer.Functions { public class UserDefinedFunctions { [SqlFunction(DataAccess = DataAccessKind.None)] public static DateTime? GetLocalTimeFromGMT(DateTime? dateTime) { if (dateTime.HasValue) return DateTime.SpecifyKind(dateTime.Value, DateTimeKind.Utc).ToLocalTime(); else return (DateTime?)null; } } } The problem is I get the following error when I try to deploy: Error 1 Cannot find the type 'Nullable`1', because it does not exist or you do not have permission. SqlServer.Functions I'm using Sql Server 2008 and Visual Studio 2008.

  • Automatically "upgrade" user settings from previous version of app.config file?

    - by SqlRyan
    Every time I compile my app and the version number changes (I have an auto-incrementing build number), I lose the user-configured app.config settings, since they're stored in the AppData folder for a specific version. Essentially, every release of my application starts from scratch as far as user settings go. While this is a mild annoyance in development, it raises the question as I approach deployment/release - if I use the app.config to store my user settings, will the user's personalized settings be hosed every time they install a patch that changes the version number of my app? If so, is there an easy way to "upgrade" the settings from the previous release? I know that using HKCU in the registry is another option, but I like the ease of the My.Settings namespace, and I'd like to stay with app.config. Another SO question asks something similar, though the answer doesn't seem that clear. Will setting my MSI so it asks the user to upgrade be enough to preserve these user-level settings?

  • How can I consume A web-service reference like a dll

    I have a small question: Can we consume a web-service reference like a sample dll? I mean something like following: 1. Add reference to assembly in the references 2. add namespace to using (using mywebservice) 3. use it in code like: var service = new mywebservice.Service1(); var result = service.GetSomething()? Why I'm asking? It's because of I tried but I get a "strange" error: Cannot load assembly "MyService.dll version, and so on". Thanks in advance!
