  • MVC Model Binding to a collection where collection does not begin with a 0 index

    - by FloatLeft
    I'm trying to perform remote validation on a property of an item within a collection. The validation works OK on the first item of the collection. The http request to the validation method looks like: /Validation/IsImeiAvailable?ImeiGadgets[0].ImeiNumber=123456789012345 However on the 2nd item where the url looks like below, the validation doesn't work /Validation/IsImeiAvailable?ImeiGadgets[1].ImeiNumber=123456789012345 Now I'm pretty sure the reason for this, is that binding wont work on a collection that doesn't begin with a zero index. My validation method has a signature as below: public JsonResult IsImeiAvailable([Bind(Prefix = "ImeiGadgets")] Models.ViewModels.ImeiGadget[] imeiGadget) Because I'm passing an item within a collection I have to bind like this yet what I'm really passing is just a single value. Is there anyway I can deal with this other than just binding it as a plain old query string. Thanks Edit: This is the quick fix to get the Imei variable but I'd rather use the model binding: string imeiNumber = Request.Url.AbsoluteUri.Substring(Request.Url.AbsoluteUri.IndexOf("=")+1);

  • openvpn in a bridge?

    - by sebelk
    I have a somewhat tricky proble to solve. We have a wireless link between 2 building. One of them has an mikrotik and below there are some vlans. Some machines of one vlan need to use openvpn to connect to a remote private lan. I put a TP-Link WR1043ND (which those machines connect to) with openwrt with ebtables just in case I need it. I've configured openwrt in such a way that all ports belongs to the same vlan. My idea was to make things as transparent as I can. It has a bridge as follows: usr/sbin/brctl-full show br-lan bridge name bridge id STP enabled interfaces br-lan 8000.f8d111565716 no eth0.1 eth0.2 Also I've added an ebtables rule: ebtables -t broute -A BROUTING -p ipv4 -j DROP So "bridge" has only one IP address. I've installed openvpn and I'm trying to bring up the tunnel but I can't still get working. Sure, someone can says why don't you use the vpn on the mikrotik, there are some reasons, the first one is I have little experience with mikrotik and I'd want to have the vpn at hand :) The problem is that openvpn is not working, because it is complaining that I have only one Ip Address on the server side. So I set up and alias interface with another IP address but is not working either: : Rejected connection attempt from IP-Client-Side:37801 due to --remote setting Is there a way to make it work?

  • What's the proper way to use sqlite at xCode?

    - by Elliot Chen
    Hi, Experts: Can you please give some suggestions on sqlite using at xcode? Within my application, I use a sqlite DB to store all local data. Two methods can be used to retrieve those data during running time. 1, Load all the data into memory at initialization stage. (More memory used, less DB open/close operation needed) 2, Read corresponding records when necessary, free the occupied memory after using. (Good habit for memory using, but much DB open/close operations needs). I prefer to use method 2, but not sure whether too many DB opening/closing operations could affect app's efficiency. Or do you think I can 'upgrade' method 2 by opening DB when app launches and closing DB when app quits? Thanks for your suggestions very much!

  • Simple Scala syntax - trying to define "==" operator - what am I missing?

    - by Alex R
    While experimenting with some stuff on the REPL, I got to a point where I needed something like this: scala class A(x:Int) { println(x); def ==(a:A) : Boolean = { this.x == a.x; } } Just a simple class with an "==" operator. Why doesn't it work??? Here's the result: :10: error: type mismatch; found : A required: ?{val x: ?} Note that implicit conversions are not applicable because they are ambiguous: both method any2ArrowAssoc in object Predef of type [A](x: A)ArrowAssoc[A] and method any2Ensuring in object Predef of type [A](x: A)Ensuring[A] are possible conversion functions from A to ?{val x: ?} class A(x:Int) { println(x); def ==(a:A) : Boolean = { this.x == a.x; } } ^ This is scala 2.8 RC1. Thanks

  • Rails 4 json return on API

    - by El - Key
    I'm creating an API on my application. I currently overrided the as_json method in my model in order to be able to get attached files as well as logo from Paperclip : def as_json( options = {} ) super.merge(logo_small: self.logo.url(:small), logo_large: self.logo.url(:large), taxe: self.taxe, attachments: self.attachments) end Then within my controller, I'm doing : def index @products = current_user.products respond_with @products end def show respond_with @product end The problem is that on the index, I don't want get all the attachments. I only need it on the show method. So I tried it : def index @products = current_user.products respond_with @products, except: [:attachments] end But unfortunately it's not working. How can I do to not send :attachments? Thanks

  • interfacing: simplified

    - by code wombat
    i've been doing some research on interfaces and a simple layman's explanation for what it truly is. For some reason people love using overly complex explanations and jargon to explain truly simple concepts (guess it makes them feel big) and i have a gut feeling it's the same in this case. so from what i could grasp, it seems like interfaces are nothing more than a way to reserve method names, their return type if any, and the type and amount of arguments they accept. so when a class implements an interface (or interfaces) it is forced to define the body of each method from the interface(s). Am i on the nose with this one or do i need to keep digging? p.s. i know javascript doesn't have support for interfaces, but i still need to understand the concept because there are quite a few places where it's shown how to emulate to an extent.

  • mvc action name in url

    - by Paul
    UPDATE: My model going into the save method is PartialViewModel, which in the save method, is pushed into the index's ContactViewModel and sent back. This wasn't clear. I am playing around with MVC3, and have a contact controller with a SaveDetails action. The index cshtml has a partial with a form whose action is pointing to this controller. When I submit the form not having completed it fully, thereby firing the validation, the url now contains the SaveDetails action name (http://localhost:7401/Contact/SaveDetails). The form code is: @using (Html.BeginForm("SaveDetails", "Contact")) { ... } The controller action looks like this: public ActionResult SaveDetails(Models.PartialsViewModel pvm) { return View("Index", new ContactViewModel{ PartialsViewModel = pvm } ); } What am I doing wrong?

  • Passing ViewData to PartialView returned from using Html.Action

    - by RWGodfrey
    I want to embed a partial view in an ASP.NET MVC page by returning it from an action method. In my base view, I would have: <%= Html.Action("MyPartialViewAction") %> My controller would have an action method like: [ChildActionOnly] public ActionResult MyPartialViewAction() { return PartialView("MyPartialView"); } I expected the returned partial view (MyPartialView) to have access to the ViewData that was set in the base page's controller action but that doesn't appear to be the case. If I insert the partial view by using the following in my base view it works: <% Html.RenderPartial("MyPartialView") %> I don't want to do that though because I want my "MyPartialViewAction" to execute logic to determine WHICH partial view to return.

  • Explicit call of Runnable.run

    - by klaudio
    Hi, I have a question. Somebody, who was working on my code before me, created some method and passed Runnable as parameter, more likely: void myMethod(Runnable runnable){ runnable.run(); } Then calling myMethod out of main looks like: public static void main(String args[]) { try { myMethod(new Runnable(){ public void run() { //do something...; }}); } catch (Throwable t) { } } So, to supply parameter to myMethod I need to instantiate object of (in this case anonymous) class implementing Runnable. My question is: is it necessary to use Runnable in this example? Can I use any different interface? I mean I can create new interface with single method i.e. interface MyInterface{ void doThis(); } then change look of myMethod: void myMethod(MyInterface myObject){ myObject.doThis(); } And of course client too: public static void main(String args[]) { try { myMethod(new MyInterface (){ public void doThis() { //do something...; }}); } catch (Throwable t) { } } Or maybe something is about Runnable?!

  • Purpose of Instance Methods vs. Class Methods in Objective-C

    - by qegal
    I have checked out all these questions... Difference Class and Instance Methods Difference between class methods and instance methods? Objective-C: Class vs Instance Methods? ...and all they explain is how instance methods are used on instances of a class and class methods are used with the class name, when a message is sent to a class object. This is helpful, but I'm curious to know why one would use a class method vs. an instance method. I'm fairly new to iOS application development, and usually use class methods, and I feel like I'm doing something wrong. Thanks in advanced!

  • Why does a delegate with no parameters compile?

    - by Ryan
    I'm confused why this compiles: private delegate int MyDelegate(int p1, int p2); private void testDelegate() { MyDelegate imp = delegate { return 1; }; } MyDelegate should be a pointer to a method that takes two int parameters and returns another int, right? Why am I allowed to assign a method that takes no parameters? Interestingly, these doesn't compile (it complains about the signature mismatches, as I'd expect) private void testDelegate() { // Missing param MyDelegate imp = delegate(int p1) { return 1; }; // Wrong return type MyDelegate imp2 = delegate(int p1, int p2) { return "String"; }; } Thanks for any help!

  • Returning messages in Smalltalk

    - by Zachary
    I have a Dictionary of objects I have created in smalltalk, which I am iterating over by enumerating it based on the key/value pairs. For value object in the dictionary, I am calling a method on that object. Based on certain conditions, I would like for this object to be able to add a new member to dictionary, and possibly delete another one. I've been looking at the 'Perform' and 'Messages' facilities in Smalltalk, but I'm not sure if it is even possible to do what I'm trying to do - is it possible to return a message (or multiple messages), which another object can process and perform? For example, could my method return 'removeKey: 19' and 'add object' at the same time? I am using GNU Smalltalk, if it matters.

  • StaX: Content not allowed in prolog

    - by RalfB

  • How to Check .Net 2.0 assembly for Calls to .Net 3.5

    - by Paul Farry
    I've found an issue I believe where an assembly is making a call to a .Net3.5 method in a .Net2.0 only environment. (None on the .Net service packs nor .Net 3.5 is installed) I'd like to know if there are any programs that I can run like FXCop to check an assembly for adherence to only making method calls that are available in .Net 2.0 without the 3.5 extensions that were added. I've been bitten by this before and I'd like to have a way to check assemblies so that before they are released they can be checked to prevent these kinds of issues. Please don't say require .Net 3.5 because whilst I'd like to go to this, it's just not possible at this point.

  • replace asp.net Response.Output with my own content

    - by WebDude
    I am trying to intercept a asp.net web request and based on a lookup replace the page thats going to be rendered to the client. example: is a request for "/about-us" comes to my web server, i will first see if i have a version of this in the database, otherwise i will revert to flat files. The version i will retrieve from the database will be a .aspx page that has to be rendered and containt web controls and inline serverside script. What is the best way to go about this? I have tried overriding the CreateHtmlTextWriter method but this seems too late in the process as the TextWriter passed to this method is already instantiated. I have also tried to Implement my own PageHandlerFactory but this seems to create an instance of Page of which i cannot seem to override its internal setting of the Response.Output stream. Amd i barking up the wrong tree here? what is the best approach to take here?

  • Managing Data Prefetching and Dependencies with .NET Typed Datasets

    - by Derek Morrison
    I'm using .NET typed datasets on a project, and I often get into situations where I prefetch data from several tables into a dataset and then pass that dataset to several methods for processing. It seems cleaner to let each method decide exactly which data it needs and then load the data itself. However, several of the methods work with the same data, and I want the performance benefit of loading data in the beginning only once. My problem is that I don't know of a good way or pattern to use for managing dependencies (I want to be sure I load all the data that I'm going to need for each class/method that will use the dataset). Currently, I just end up looking through the code for the various classes that will use the dataset to make sure I'm loading everything appropriately. What are good approaches or patterns to use in this situation? Am I doing something fundamentally wrong? Although I'm using typed datasets, this seems like it would be a common situation where prefetching data is used. Thanks!

  • Unit testing class in a web service in .net

    - by Dan Bailiff
    After some digging here, I took the advice in this thread: http://stackoverflow.com/questions/371961/how-to-unit-test-c-web-service-with-visual-studio-2008 I've created a separate class and my web service class is just a wrapper for that one. The problem is that when I try to create a unit test project in VS2008, it insists on creating a unit test that acts like I'm testing the web service calls instead of the class I specified. I can't get to the class I'm trying to test. I have a web service "subscription_api.asmx". The code behind is "subscription_api.cs" which contains the web method wrapper calls to the real code at "subscription.cs". I would expect to be able to do the following: [TestMethod()] public void GetSystemStatusTest() { subscription sub = new subscription(); XmlNode node = sub.GetSystemStatusTest(); Assert.IsNotNull(node); } But instead I get this mess which is autogenerated from VS'08: /// <summary> ///A test for GetSystemStatus ///</summary> // TODO: Ensure that the UrlToTest attribute specifies a URL to an ASP.NET page (for example, // http://.../Default.aspx). This is necessary for the unit test to be executed on the web server, // whether you are testing a page, web service, or a WCF service. [TestMethod()] [HostType("ASP.NET")] [AspNetDevelopmentServerHost("C:\\CVSROOT\\rnr\\pro\\product\\wms\\ss\\subscription_api", "/subscription_api")] [UrlToTest("http://localhost/subscription_api")] public void GetSystemStatusTest() { subscription_Accessor target = new subscription_Accessor(); // TODO: Initialize to an appropriate value XmlNode expected = null; // TODO: Initialize to an appropriate value XmlNode actual; actual = target.GetSystemStatus(); Assert.AreEqual(expected, actual); Assert.Inconclusive("Verify the correctness of this test method."); } Additionally, there is a "subscription_api.accessor" in the Test References folder. When I try this: [TestMethod()] public void GetSystemStatusTest2() { subscription_Accessor sub = new subscription_Accessor(); XmlNode node = sub.GetSystemStatus(); Assert.IsNotNull(node); } I get an error: Test method subscription_api.Test.subscriptionTest.GetSystemStatusTest2 threw exception: System.TypeInitializationException: The type initializer for 'subscription_Accessor' threw an exception. ---> System.ArgumentNullException: Value cannot be null. I'm really new to unit testing and feel lost. How can I create a unit test just for my subscription class in "subscription.cs" without testing the web service? Am I limited to testing within the same project (I hope not)? Do I have to put the target class in its own project outside of the web service project?

  • Upload image using CURL + PHP via remote form

    - by user253530
    I have a few images that i need to upload using an online form. So far here's my code $info = array('test title','1234','virginia','@'.realpath('e:\wamp\www\1.jpg'),'@'.realpath('e:\wamp\www\2.jpg'),'@'.realpath('e:\wamp\www\3.jpg'),'@'.realpath('e:\wamp\www\4.jpg'),'test description'); $post->postAd($url, $info); The $info array is processed in the postAd method and it's being sent as an associative array using a method from a Curl class i have (it has been tested and worked nicely with everything i needed to do so far with curl). The problem is that the data is completed correctly on the form but the images are not uploaded. Can anyone help with advices/code/guidance?

  • java statistics collection for performance evaluation

    - by user384706
    What is the most efficient way to collect and report performance statistic analysis from an application? If I have an application that uses a series of network apis, and I want to report statistics at runtime, e.g. Method doA() was called 3 times and consumed on avg 500ms Method doB() was called 5 times and consumed on avg 1200ms etc Then, I thought of using a well defined data structure (of collection) that each thread updates per remote call, and this can be used for the report. But I think that it will make the performance worse, for the time spend for statistics collection. Am I correct? How would I procceed if I used a background thread for this, and the other threads that did the remote calls were unaware of this collection gathering? Thanks

  • FindBugs and CheckForNull on classes vs. interfaces

    - by ndn
    Is there any way to let FindBugs check and warn me if a CheckForNull annotation is present on the implementation of a method in a class, but not on the declaration of the method in the interface? import javax.annotation.CheckForNull; interface Foo { public String getBar(); } class FooImpl implements Foo { @CheckForNull @Override public String getBar() { return null; } } public class FindBugsDemo { public static void main(String[] args) { Foo foo = new FooImpl(); System.out.println(foo.getBar().length()); } } I just discovered a bug in my application due to a missing null check that was not spotted by FindBugs because CheckForNull was only present on FooImpl, but not on Foo, and I don't want to spot all other locations of this problem manually.
