• Windows Azure access POST data

  - by Mohamed Nuur

  Ok, so I can't seem to find decent Windows Azure examples. I have a simple hello world application that's based on this tutorial. I want to have custom output instead of JSON or XML. So I created my interface like: [ServiceContract] public interface IService { [OperationContract] [WebInvoke(UriTemplate = "session/create", Method = "POST")] string createSession(); } public class MyService : IService { public string createSession() { // get access to POST data here: user, pass string sessionid = Session.Create(user, pass); return "sessionid=" + sessionid; } } For the life of me, I can't seem to figure out how to access the POST data. Please help. Thanks!

• Randomly generate sound from onClick and onShake events?

  - by Aaron

  I've literally looked everywhere on the net and found very little clarification on how to do this. Pretty much, I have 8 sound files laid out in an array.xml file and I need to play a randomly chosen file ONCE per or onClick or onShake. First off, what technique should I use to achieve this? ARRAY-RANDOM- STRING-PLAY? RANDOM INT-PLAY? RANDOM INT-STRING-PLAY? Any kind of direction will help greatly cause I'm almost 3 weeks worth of research into this. *NOTE: MediaPlayer mp = MediaPlayer.create(JelloMan.this, R.raw.sound) ...is what I'm stuck on being you can't replace the "R.raw" part with a string...

• c# const in jQuery?

  - by Cristian Boariu

  Hi guys, I have this piece of code in javascript: var catId = $.getURLParam("category"); In my asp.net and c# code for "category" query string i use a public const: public const string CATEGORY = "category"; so if i want to change the query string parameter to be "categoryTest" i only change this const and all the code is updated. Now the question is: how can i do something similar for the javascript i have in the same application (so i want to use the same constant)? I mean i want something like this: var catId = $.getURLParam(CQueryStringParameters.CATEGORY); but because there are none asp.net tags, my const is not interpreted... Any workaround?

• Spring overloaded constructor injection

  - by noob

  This is the code : public class Triangle { private String color; private int height; public Triangle(String color,int height){ this.color = color; this.height = height; } public Triangle(int height ,String color){ this.color = color; this.height = height; } public void draw() { System.out.println("Triangle is drawn , + "color:"+color+" ,height:"+height); } } The Spring config-file is : <bean id="triangle" class="org.tester.Triangle"> <constructor-arg value="20" /> <constructor-arg value="10" /> </bean> Is there any specific rule to determine which constructor will be called by Spring ?

• Authentication from url in Restlet

  - by DutrowLLC

  I've been using Restlets "ChallengeResponse" mechanism to authenticate users so far. ChallengeResponse challengeResponse = getRequest().getChallengeResponse(); if( challengeResponse == null ){ throw new RuntimeException("not authenticated"); } String login = challengeResponse.getIdentifier(); String password = new String(challengeResponse.getSecret()); From my understanding, "ChallengeResponse" requires that the username and password are put into headers. However a client needs to put the credentials into the url like so: https://username:[email protected]/my_secure_document When I looked at what was actually sent, it looks like the password is being hashed. What is the proper way to authenticate in this fashion using Restlet?

• XmlTextReader issue

  I'm try to parse this xml, but c# keeps throwing an exception saying it has invalid characters.

• Parsing a dynamic value with Lift-JSON

  - by Surya Suravarapu

  Let me explain this question with an example. If I have a JSON like the following: {"person1":{"name": "Name One", "address": {"street": "Some Street","city": "Some City"}}, "person2":{"name": "Name Two", "address": {"street": "Some Other Street","city": "Some Other City"}}} [There is no restriction on the number of persons, the input JSON can have many more persons] I could extract this JSON to Persons object by doing var persons = parse(res).extract[T] Here are the related case classes: case class Address(street: String, city: String) case class Person(name: String, address: Address, children: List[Child]) case class Persons(person1: Person, person2: Person) Question: The above scenario works perfectly fine. However the need is that the keys are dynamic in the key/value pairs. So in the example JSON provided, person1 and person2 could be anything, I need to read them dynamically. What's the best possible structure for Persons class to account for that dynamic nature.

• Memory consumption of resource manager

  - by Quang Anh

  I'm writing a resource manager, which is required to be fast and has small memory foot-print. For example, I have an resource class class Abc { string m_name; string m_path; string handle; void SomeFunctions(); } And so on. Now I create and List and add 5000 items to it. How much memory will it consume? One more question: Can I find items base on handle number only, which is the int part of the Tuple?

• JAVA Inheritance Generics and Casting.

  - by James Moore

  Hello, I have two classes which both extends Example. public class ClassA extends Example { public ClassA() { super("a", "class"); } .... } public class ClassB extends Example { public ClassB() { super("b", "class"); } .... } public class Example () { public String get(String x, String y) { return "Hello"; } } So thats all very well. So suppose we have another class called ExampleManager. With example manager I want to use a generic type and consequently return that generic type. e.g. public class ExampleManager<T extends Example> { public T getExample() { return new T("example","example"); // So what exactly goes here? } } So where I am returning my generic type how do i get this to actually work correctly and cast Example as either classA or classB? Many Thanks

• Typed DefaultListModel to avoid casting

  - by Thomas R.

  Is there a way in java to have a ListModel that only accepts a certain type? What I'm looking for is something like DefaultListModel<String> oder TypedListModel<String>, because the DefaultListModel only implements addElement(Object obj) and get(int index) which returns Object of course. That way I always have to cast from Object to e.g. String and there is no guarantee that there are only strings in my model, even though I'd like to enforce that. Is this a flaw or am I using list models the wrong way?

• php mysql flex unicode

  - by JonoB

  I have a problem with saving the £ symbol to a mysql database. I am running a flex front end, with a php + mysql backend When I save a record from flex, the string gets sent to the server as "This amount is £10" php views the string as above, and when it gets saved into the DB, it gets saved as "This amount is £10". My understanding is that this is correct based on MySQL or PHP is appending a  whenever the £ is used I now retrieve the above record, and it gets sent to flex as "This amount is £10". Flex correctly displays this in a textarea as "This amount is £10" I change another field in the same record in flex, and re-save the transaction. The string now gets sent to the server as "This amount is £10" The record is now saved into the DB as "The amount is £10". Each time the record is re-saved, this effect snowballs. Thanks for any advice you can give.

• Differences setting content in Forms.WebBrowser control via DocumentText vs. Url

  - by jeffamaphone

  If I generate some HTML and have it in a string and then say: myWebBrowser.DocumentText = string; It seems to work just fine, except none of the images load (I get the broken image graphic). If, however, I write the string to a file and then say: myWebBrowser.Url = new Uri("file://myfile.html"); Everything works just fine. My question is, what's going on under the covers here that is different? I've verified in both cases that the path to the images (via RClick-View Source) is the same and that all the images do, indeed, exist. In both cases the HTML is exactly the same. Any light that could be shed on this would be appreciated. Thanks!

• How do I use Some/None Options in this F# example?

  - by Phobis

  I am new to F# and I have this code: if s.Contains("-") then let x,y = match s.Split [|'-'|] with | [|a;b|] -> int a, int b | _ -> 0,0 Notice that we validate that there is a '-' in the string before we split the string, so the match is really unnecessary. Can I rewrite this with Options? I changed this code, it was originally this (but I was getting a warning): if s.Contains("-") then let [|a;b|] = s.Split [|'-'|] let x,y = int a, int b NOTE: I am splitting a range of numbers (range is expressed in a string) and then creating the integer values that represent the range's minimum and maximum.

• C++: call original definition of operator equals

  - by Luis Daniel

  I am overloading the operator equals (==) as show bellow: #include <string> #include <algorithm> bool operator == (std::string str1, std::string str2) { std::transform(str1.begin(), str1.end(), str1.begin(), ::tolower); std::transform(str2.begin(), str2.end(), str2.begin(), ::tolower); return (str1 == str2); } but, the problem appear on line return (str1 == str2), because operator == is called recursively. So, how can I call the original definition for operator equals (not the overloaded) ? Best regards

• 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?
