  • Get REST Call is not returning the string I put in url

    - by wizage
    I have very simple code: using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Net.Http; using System.Web.Http; namespace Calculator.Controllers { public class CalcController : ApiController { public string Get(string type) { return type; } } } And this is what it returns when I type in http://www.example.com/api/calc/test <string xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/2003/10/Serialization/" i:nil="true"/> When I use http://www.example.com/api/calc/?test=test it returns this: <string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">type</string> How to I make it so I can just do the top one instead of the bottom one?

  • Deploying WPF applications with SQL Server

    - by SiN
    Ok so I'm developing a WPF application that makes heavy use of SQL Server. I've been asked to create an installer package that checks whether the client already has SQL Server Express 2005 already installed, his operating system (64bit Vs x86) and install the required SQL Server instance if needed. I'm then required to automatically map my App.config's connection string to the SQL Server's connection string and run a script to create my database. Is it just me, or does this look like a lot of hard work? Any idea where to start? Edit: Ok should I move to SQL Server Compact edition? Thanks!

  • (C++) While reading a file (ifstream), is there any way to direct it to make a new line?

    - by Enzo
    While reading a file (ifstream), is there any way to direct it to make a new line? For instance, I would like for THIS to happen: myfilearray[1]array[2]endl; Obviously, the "endl" just isn't allowed. Is there another way to do this? Edit---thanks for the quick responses guys! From a text file, I'm trying to store two strings from that file into arrays and then do the same with the next line (or until I desire, using a for loop) Using strings is important to me as it will make my future program a lot more flexible.

  • Read data from specific memory address

    - by rapid
    Hello. How can I read (and put into new variable) data stored at specific memory address? For instance I know that: <nfqueue.queue; proxy of <Swig Object of type 'queue *' at 0xabd2b00> > And I want to have data stored at 0xabd2b00 in new variable so that I can work and use all functionalities of the object. Let's assume that I don't have access to the original variable that created this object.

  • Implementing an ActiveRecord before_find

    - by thaiyoshi
    I am building a search with the keywords cached in a table. Before a user-inputted keyword is looked up in the table, it is normalized. For example, some punctuation like '-' is removed and the casing is standardized. The normalized keyword is then used to find fetch the search results. I am currently handling the normalization in the controller with a before_filter. I was wondering if there was a way to do this in the model instead. Something conceptually like a "before_find" callback would work although that wouldn't make sense on for an instance level.

  • jsp and java beans

    - by JRR
    I am building jsp pages hosted on tomcat and am wondering if the bean instances referenced in each jsp are stateless / stateful? How do those bean instances come about? Are they (re-)created each time when the page is visited? Do I need to worry about two different users visiting the same page at the same time and getting hold of the same bean instance? In general I find the interaction between jsp and beans quite confusing so I'd appreciate if someone can refer a tutorial / explanation of those concepts. Thanks!

  • Java classloader delegation model ?

    - by Tony
    When calling a loadClass() on a class loader, the class loader firstly check the class if had been loaded or directly delegate this check to it's parent class loader ? Java api says: When requested to find a class or resource, a ClassLoader instance will delegate the search for the class or resource to its parent class loader before attempting to find the class or resource itself. But there's a specific chapter about class loader in the book <java reflection in action> and says: Class loader calls findLoadedClass to check if the class has been loaded already.If a class loader does not find a loaded class, calls loadClass on the parent class loader. which is correct ?

  • ListView Item Detail Screen: New or Same Activity?

    - by stormin986
    I have a listview where each item correlates to an instance of an item in an array. When the user selects an item, it will bring up a 'Details' page that reads and displays other data members of the list item. Would this be better implemented with the Details page as its own activity, or a new view within the same activity? Pros and cons of each? A new activity makes my job a little easier in terms of handling the 'back' button, but then I have the challenge of how do I pass the rest of the data structure to the new activity since I can't bundle it up (unless I serialize it).

  • OneToMany association updates instead of insert

    - by Shvalb
    I have an entity with one-to-many association to child entity. The child entity has 2 columns as PK and one of the column is FK to the parent table. mapping looks like this: @OneToMany(cascade = {CascadeType.ALL}, fetch = FetchType.EAGER ) @JoinColumn(name="USER_RESULT_SEQUENCES.USER_RESULT_ID", referencedColumnName="USER_RESULT_ID", unique=true, insertable=true, updatable=false) private List<UserResultSequence> sequences; I create an instance of parent and add children instances to list and then try to save it to DB. If child table is empty it inserts all children and it works perfectly. if the child table is not empty it updates existing rows! I don't know why it updates instead of inserts, any ideas why this might happen?? Thank you!

  • iPhone view architecture question

    - by Joe
    So I have (for instance) three views: A: root view B: a view functionally identical to root C: a data entry view which collects a few piece of info What I'm trying to do is reuse C to supply the data it collects to either A or B. It should supply the data to whichever of the two it is pushed onto. The data for A is similar, but functionally distinct, to what collects for B. Right now, I'm passing data from C to A or B via a singleton class. What I'm trying to avoid is having two instances of C, one to supply data to A and B (because, in actuality, the program will have 5 total views like C. Does the question make sense?

  • Custom DDL Templates for Visual Studio 2010

    - by Stacey
    I was wondering if anyone knows of some good community distributed custom DDL templates for Entity Framework 4.0. The default DDL to SQL10 Works well enough, but we're looking to do some customization to the naming convention that it just isn't offering us. I'm not really finding many samples out there of people doing this, so I was hoping someone might know of a resource I'm overlooking (perhaps I am searching for it wrong, or misunderstanding how the whole process works) Specifically we're wanting to change up how it writes out fields from relationships. For instance, the default template puts in.. tablename_propertyendpoint_propertyname. We're wanting to find tune this to our naming scheme a little more. And none of us can quite figure out where in the .tt files it is doing this exact behavior.

  • .net load balancing for server

    - by user1439111
    Some time ago I wrote server software which is currently running at it's max. (3k users average). So I decided to rewrite certain parts so I can run the software at another server to balance it's load. I can't simply start another instance of the server since there is some data which has to be available to all users. So I was thinking of creating a small manager and all the servers connect and send their (relevant)data to the manager. But it also got me thinking about another problem. The manager could also reach it's limits which is exactly what i'm trying to prevent in the future. So I would like to know how I could fix this problem. (I have already tried to optimize critical parts of the software but I can't optimize it forever)

  • Running sql scripts against an attached database?

    - by Will
    I've got an MDF attached to an instance of Sql Server 2008 Express, and I need to run some sql scripts against it to generate tables, indexes, etc. But I can't figure out how to get this to work. If I load the scripts in Visual Studio, it only allows me to connect to the server and run it against a database. I can't choose a different provider (Microsoft Sql Server Database File), so I can't select my MDF. This leaves me the only option of running the script as individual queries, but that won't work as it appears it doesn't support TSQL CREATE statements. How can I run my sql script against an attached database?

  • Is it acceptable to design my GLSurfaceView as a main control class?

    - by Omega
    I'm trying to structure a game I'm making in Android so that I have a sound, flexible design. Right now I'm looking at where I can tie my games rules engine and graphics engine together and what should be in between them. At a glance, I've been eying my implementation of GLSurfaceView, where various screen events are captured. My rationale would be to create an instance of my game engine and graphics engine here and receive events and state changes to trigger updates of either where applicable. Further to this, in the future, the GLSurfaceView implementation could also store stubs for players during a network game and implementations of computer opponents and dispatch them appropriately. Does this seem like a sensible design? Are there any kinds of improvements I can make? Thanks for any input!

  • Singleton pattern with Web application, Not a good idea!!

    - by Tony
    Hi I found something funny, I notice it by luck while I was debugging other thing. I was applying MCP pattern and I made a singleton controller to be shared among all presentations. Suddenly I figured out that some event is called once at first postback, twice if there is two postback, 100 times if there is 100 postbacks. because Singleton is based on a static variable which hold the instance, and the static variable live across postbacks, and I wired the event assuming that it will be wired once, and rewired for each postback. I think we should think twice before applying a singleton in a web application, or I miss something?? thanks

  • log (1-var) operation in C

    - by heike
    I am trying to code this algorithm. I am stuck in the part of log((1.0-u)/u))/beta; As I understand, I can not get the result of this in C, as it will always return me with negative value log (returning imaginary value). Tried to print the result of log(1-5) for instance, it gives me with Nan. How can I get the result of double x = (alpha - log((1.0-u)/u))/beta then? Would appreciate for any pointers to solve this problem. Thank you

  • JBoss 4.0.5 startup takes 15 minutes deploying a single war file

    - by dkblinux98
    This instance of JBoss deploys several war files. The rest of the JBoss startup takes about 5 minutes or less. But when it gets to one particular war file, startup just hangs with no further output to the jboss log. It waits there for about 15 minutes and then suddenly the war starts deploying. The rest of the JBoss startup is then fine. What I want to know is what steps do you recommend I take to diagnose the cause of this condition? It is not possible to upgrade this site to a newer version of JBoss nor java (currently 1.5.0.7). It is running on 32-bit CentOS 5.3 Linux on 3 xen-based virtual servers in a load balanced configuration. The code is common to all three servers via an nfs share. This same issue was seen, however, when the 3 servers were physical and the code was local to each server. The servers are each 2 cpu, 4GB RAM servers.

  • Assign parameters to function according to parameter names

    - by Korcholis
    I have an assoc array with a list of what are parameters to me. Here's an example: array( 'param1' => 'value1', 'param4' => 'value4', 'param3' => 'value3', 'param2' => 'value2', ); Note that they may come unsorted. Now, is there a way I can make a call (static or from an instance, using call_user_func_array or similar) and correctly pass each value to each parameter? Just to be sure, an example function I'd like to call using that parameter array is one such this: exampleFunction($param1, $param2, $param3, $param4) { ... } PS: Reflection is great, but I'm concerned about execution times (which, at least, in Java tends to increase a lot when using Reflection). If you know any other way to do so, it would be awesome.

  • A 3-D grid of regularly spaced points

    - by Jack
    I want to create a list containing the 3-D coords of a grid of regularly spaced points, each as a 3-element tuple. I'm looking for advice on the most efficient way to do this. In C++ for instance, I simply loop over three nested loops, one for each coordinate. In Matlab, I would probably use the meshgrid function (which would do it in one command). I've read about meshgrid and mgrid in Python, and I've also read that using numpy's broadcasting rules is more efficient. It seems to me that using the zip function in combination with the numpy broadcast rules might be the most efficient way, but zip doesn't seem to be overloaded in numpy.

  • Configure WCF Service Behavior using database

    - by Achhar
    We use database to centralize our configuration. As part of it, I want to store the standard service behaviors configuration like expose service metatdata, service debug, service throttling for a service inside database rather than in web/app.config. I was planing to store the configuration for a behavior in database as XML. For e.g. <serviceDebug includeExceptionDetailsinFault=true / What I am struggling with is once I read this XML from database how do I create ServiceDebugBehavior instance from it and apply it to my service host? I have tried using XML Serializer but didn't had success. Any thoughts on how this could be achieved or any alternate solutions?

  • Handling dynamic number of columns

    - by Whistle
    I'm developing a CMS of sorts, and I want to give my users the possibility of customizing the display. More precisely, I want to give them the ability to choose to display or hide the left column, the right column and/or the top div. The middle column cannot be hidden since this is where the actual content will show, whereas the other columns are for navigation or side menus. I've been looking for a way to make this as smart and flexible as possible. For now I'm using a MasterPage, but that seems to be too constraining. For instance, with MasterPage you need to add a ContentPlaceHolder control in every of your ASPX pages. What are the best practices in this area? I guess a simpler way of saying this would be "I want to create a template system over which I have complete control".

  • Are sessions modifiable by the client/user?

    - by Sev
    In my PHP Web-App I use sessions to store the user's data. For exmaple, if a user logs in, then an instance of the User class is generated and stored in a Session. I have access levels associated with each user to determine their privileges. Store the user in a session by: $_SESSION['currentUser'] = new User($_POST['username']); For example: if($_SESSION['currentUser'] -> getAccessLevel() == 1) { //allow administration functions } where getAccessLevel() is simply a get method in the User class that returns the _accesslevel member variable. Is this secure? Or can the client somehow modify their access level through session manipulation of some sort?

  • Targeting row when responding with js rails

    - by berto77
    I have an application where a user can vote on reviews. They can vote up or down. Now when there's a listing of reviews, I have a problem targeting the review the user voted on. I'm using a respon_to block in my rails controller and responding with js. So for instance, I have a vote_up method, and a vote_up.js.erb template. in that template, I have the following: var id = $('article.comment').attr('id').split('_')[1]; alert("id: " + id); $('.votecomment_' + id).find('.score').html("<%= @review2.vote_total %>"); I'm just alerting the id. The problem is that the id always returns the value of the first review found on the page. How can I pass the context aka this, to javascript, so I can figure out which review to target?
