  • Similar route mapping

    - by Denis Agarev
    I need to map to create controller what must response to two urls: "http://localhost/api/controller?id=1" (where only id value can change) "http://localhost/api/controller/anotherId/someconst" (where anotherId is the only one changing part) i map it to such route: routes.MapHttpRoute("Test", "api/{controller}/{id}/{someconst}", new { controller = "Test", someconst = RouteParameter.Optional }); And have to methods in my controller: public void Get(int id) { ... } public void Get(int anotherId, string someconst ) { ... } It works...But it doesn't look nice...cause "string someconst" is not a param, it's just a const part of url. But if i remove "string someconst" param second url wouldn't work. Is it possible to map one controller to two routes to resolve this urls to make it clear without fake param which is a const in fact?

  • How to generate tests with different names in testng, java?

    - by Ula Karzelek
    I'm using testng to run selenium based tests in java. I have a bunch of repeated tests. Generally they do all the same except of test name and one parameter. I want to automate generation of it. I was thinking about using factory. Is there a way to generate tests with different name? What would be the best approach to this? As for now I have something like below and I want to create 10 tests like LinkOfInterestIsActiveAfterClick @Test(dependsOnGroups="loggedin") public class SmokeTest extends BrowserStartingStoping{ public void LinkOfInterestIsActiveAfterClick(){ String link = "link_of_interest"; browser.click("*",link); Assert.assertTrue(browser.isLinkActive(link)); } } My xml suite is auto-generated from java code. test names are crucial for logging which link is active, and which one is not.

  • Loopj Android Async Http - onFailure not fired

    - by Ashley Staggs
    I am using the great async http library from loopj, but I have run into a small snag. If the user has no internet connection or loses their connection, the app just won't return anything. This part is expected, but it also doesn't fire the onFailure method. Also, the code I have used when there is an internet connection does work so there is no problem on the server end. Here is some code that is stripped down to the minimum. It also doesn't work (I have tested this too) String url = getString(R.string.baseurl) + "/appconnect.php"; client.getHttpClient().getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true); client.get(url, null, new JsonHttpResponseHandler() { @Override public void onSuccess(JSONArray response) { Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show(); } @Override public void onFailure(Throwable e, JSONArray errorResponse) { Toast.makeText(getApplicationContext(), "Failure", Toast.LENGTH_SHORT).show(); } }); Thanks, Ashley

  • C# Pass Generics At Runtime

    - by TheCloudlessSky
    I have a method like the following: public IEnumerable<T> GetControls<T>() : where T : ControlBase { // removed. } I then created a class: public class HandleBase<TOwner> : ControlBase : TOwner { // Removed } I'd like to be able to call GetControls<HandleBase<this.GetType()>>; where it would use the type of THIS class to pass to the HandleBase. This would in essentially get all HandleBase that have an owner of THIS type. How can I achieve this?

  • Is this a legitimate implementation of a 'remember me' function for my web app?

    - by user246114
    Hi, I'm trying to add a "remember me" feature to my web app to let a user stay logged in between browser restarts. I think I got the bulk of it. I'm using google app engine for the backend which lets me use java servlets. Here is some pseudo-code to demo: public class MyServlet { public void handleRequest() { if (getThreadLocalRequest().getSession().getAttribute("user") != null) { // User already has session running for them. } else { // No session, but check if they chose 'remember me' during // their initial login, if so we can have them 'auto log in' // now. Cookie[] cookies = getThreadLocalRequest().getCookies(); if (cookies.find("rememberMePlz").exists()) { // The value of this cookie is the cookie id, which is a // unique string that is in no way based upon the user's // name/email/id, and is hard to randomly generate. String cookieid = cookies.find("rememberMePlz").value(); // Get the user object associated with this cookie id from // the data store, would probably be a two-step process like: // // select * from cookies where cookieid = 'cookieid'; // select * from users where userid = 'userid fetched from above select'; User user = DataStore.getUserByCookieId(cookieid); if (user != null) { // Start session for them. getThreadLocalRequest().getSession() .setAttribute("user", user); } else { // Either couldn't find a matching cookie with the // supplied id, or maybe we expired the cookie on // our side or blocked it. } } } } } // On first login, if user wanted us to remember them, we'd generate // an instance of this object for them in the data store. We send the // cookieid value down to the client and they persist it on their side // in the "rememberMePlz" cookie. public class CookieLong { private String mCookieId; private String mUserId; private long mExpirationDate; } Alright, this all makes sense. The only frightening thing is what happens if someone finds out the value of the cookie? A malicious individual could set that cookie in their browser and access my site, and essentially be logged in as the user associated with it! On the same note, I guess this is why the cookie ids must be difficult to randomly generate, because a malicious user doesn't have to steal someone's cookie - they could just randomly assign cookie values and start logging in as whichever user happens to be associated with that cookie, if any, right? Scary stuff, I feel like I should at least include the username in the client cookie such that when it presents itself to the server, I won't auto-login unless the username+cookieid match in the DataStore. Any comments would be great, I'm new to this and trying to figure out a best practice. I'm not writing a site which contains any sensitive personal information, but I'd like to minimize any potential for abuse all the same, Thanks

  • Call the method of base Class which was over ridden

    - by Abhijith Venkata
    I have illustrated my question in this example class Car { public void start(){ System.out.println("Car Started!!!"); } } class Mercedes extends Car { public void start(){ System.out.println("Mercedes Started!!!"); } } Now, in my main program, I write Mercedes m = new Mercedes(); m.start(); It prints: Mercedes Started!!! How do I call the start() method of Car class using the same object so that the output can be Car Started!!!. Edit: Actually It was asked in an interview I attended. I gave the super keyword answer. But the interviewer denied it. He said he'd give me a hint and said Virtual Function. I have no idea how to use that hint.

  • 'Lexical' scoping of type parameters in C#

    - by leppie
    I have 2 scenarios. This fails: class F<X> { public X X { get; set; } } error CS0102: The type 'F' already contains a definition for 'X' This works: class F<X> { class G { public X X { get; set; } } } The only logical explanation is that in the second snippet the type parameter X is out of scope, which is not true... Why should a type parameter affect my definitions in a type? IMO, for consistency, either both should work or neither should work. Any other ideas? PS: I call it 'lexical', but it probably is not not the correct term.

  • Direct comparator in Java out of the box

    - by KARASZI István
    I have a method which needs a Comparator for one of its parameters. I would like to pass a Comparator which does a normal comparison and a reverse comparator which does in reverse. java.util.Collections provides a reverseOrder() this is good for the reverse comparison, but I could not find any normal Comparator. The only solution what came into my mind is Collections.reverseOrder(Collections.reverseOrder()). but I don't like it because the double method calling inside. Of course I could write a NormalComparator like this: public class NormalComparator<T extends Comparable> implements Comparator<T> { public int compare(T o1, T o2) { return o1.compareTo(o2); } } But I'm really surprised that Java doesn't have a solution for this out of the box.

  • Obtaining reference to Class instance by string name - VB.NET

    - by Jeff Williams
    Is it possible using Reflection or some other method to obtain a reference to a specific class instance from the name of that class instance? For example the framework for the applications i develop heavily uses public class instances such as: Public bMyreference as MyReference = new MyReference Then throughout the application bMyReference is used by custom controls and code. One of the properties of the custom controls is the "FieldName" which references a Property in these class instances (bMyReference.MyField) as a string. What i would like to be able to do is analyze this string "bMyReference.MyField" and then refer back to the actual Instance/Property. In VB6 I would use an EVAL or something simular to convert the string to an actual object but this obviously doesn't work in VB.net What I'm picturing is something like this Dim FieldName as String = MyControl.FieldName ' sets FielName to bMyReference.MyField Dim FieldObject() as String = FieldName.Split(".") ' Split into the Object / Property Dim myInstance as Object = ......... ' Obtain a reference to the Instance and set as myInstance Dim myProperty = myInstance.GetType().GetProperty(FieldObject(1))

  • Why isn't the "this." command needed in this constructor? (java)

    - by David
    I'm reading a book about java. It just got to explaining how you create a class called "deck" which contains an array of cards as its instance variable(s). Here is the code snippit: class Deck { Card[] cards; public Deck (int n) { cards = new Card[n]; } } why isn't the this. command used? for example why isn't the code this: class Deck { Card[[] cards; public Deck (int n) { this.cards = new Card[n]; } }

  • Can running object be garbage collected?

    - by Kugel
    I have a simple class: public class Runner { public void RunAndForget(RunDelegate method) { ThreadPool.QueueUserWorkItem(new WaitCallback(Run), method); } private void Run(object o) { ((RunDelegate )o).Invoke(); } } And if I use this like so: private void RunSomethingASync() { Runner runner = new Runner(); runner.FireAndForget(new RunDelegate(Something)); } Is there any danger using it like this? My C++ guts tell me that runner object should be destroyed after RunSomethingASync is finished. Am I right? What happens then to the method running on different thread? Or perhaps it is other way around and runner will not be collected? That would be a problem considering I may call RunSomethingASync() many times.

  • Calling a void async. - Event based pattern, or another method?

    - by alex
    I have a class that basically stores files in amazon s3. Here is what it looks like (simplified) public class S3FileStore { public void PutFile(string ID, Stream content) { //do stuff } } In my client app, I want to be able to call: var s3 = new() S3FileStore(); s3.PutFile ("myId", File.OpenRead(@"C:\myFile1")); s3.PutFile ("myId", File.OpenRead(@"C:\myFile2")); s3.PutFile ("myId", File.OpenRead(@"C:\myFile3")); I want this to be an asynchronous operation - I want the S3FileStore to handle this (i don't want my caller to have to execute PutFile asynchronously so to speak) but, i want to be able to trap exceptions / tell if the operation completed for each file. I've looked at event based async calls, especially this: http://blogs.windowsclient.net/rendle/archive/2008/11/04/functional-shortcuts-2-event-based-asynchronous-pattern.aspx However, I can't see how to call my PutFile (void) method? Are there any better examples?

  • C++ Singleton Constructor and Destructor

Way 1: class Singleton { public: ~Singleton() { } private: Singleton() { } }; Way 2: class Singleton { public: ~Singleton(); private: Singleton(); }; In the source .cc file: Singleton::Singleton() { } Singleton::~Singleton() { } Initially, I have the implementation in a source file, but I was asked to remove it. Does anyone know why?

We need to: Prevent all external (public) users from accessing the URL. Permit specific internal users to access the page, only from certain IPs or networks. Should this access control be done at the (a) network level, (b) application level, etc.?
