  • DataContractSerializer and XSLT not Serializing Class Properties

    - by Russ Clark
    I've written a simple Employee class that I'm trying to serialize to an XDocument and then use XSLT to transform the document to a page that displays both the properties (Name and ID) from the Employee class, and an html form with 2 radio buttons (Approve and Reject) and a submit button. Here is the Employee class: [Serializable, DataContract(Namespace="XSLT_MVC.Controllers/")] public class Employee { [DataMember] public string Name { get; set; } [DataMember] public int ID { get; set; } public Employee() { } public Employee(string name, int id) { Name = name; ID = id; } public XDocument GetDoc() { XDocument doc = new XDocument(); var serializer = new DataContractSerializer(typeof(Employee)); using (var writer = doc.CreateWriter()) { serializer.WriteObject(writer, this); writer.Close(); } return doc; } } And here is the XSLT file: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" > <xsl:output method="html" indent="yes"/> <xsl:template match="/"> <html> <body> <xsl:value-of select="Employee/Name"/> <br /> <xsl:value-of select="Employee/ID"/> <br /> <form method="post" action="/Home/ProcessRequest?id={Employee/ID}"> <input id="Action" name="Action" type="radio" value="Approved"></input> Approved <br /> <input id="Action" name="Action" type="radio" value="Rejected"></input> Rejected <br /> <input type="submit" value="Submit"></input> </form> </body> </html> </xsl:template> </xsl:stylesheet> When I run this, all I get is the html form with the 2 radio buttons and the submit button, but not the properties from the Employee class. I saw a separate StackOverflow post that said I need to change the <xsl:template match="/"> to match on the namespace of my Employee class like this: <xsl:template match="/XSLT_MVC.Controllers"> but when I do that, now all I get are the Employee properties, and not the html form with the 2 radio buttons and the submit button. Does anyone know what needs to be done so that my transform will select and display both the Employee properties and the html form?

  • How to structure a Genetic Algorithm class hierarchy?

    - by MahlerFive
    I'm doing some work with Genetic Algorithms and want to write my own GA classes. Since a GA can have different ways of doing selection, mutation, cross-over, generating an initial population, calculating fitness, and terminating the algorithm, I need a way to plug in different combinations of these. My initial approach was to have an abstract class that had all of these methods defined as pure virtual, and any concrete class would have to implement them. If I want to try out two GAs that are the same but with different cross-over methods for example, I would have to make an abstract class that inherits from GeneticAlgorithm and implements all the methods except the cross-over method, then two concrete classes that inherit from this class and only implement the cross-over method. The downside to this is that every time I want to swap out a method or two to try out something new I have to make one or more new classes. Is there another approach that might apply better to this problem?

  • Using Unity and interfaces, how do I create a concrete class that implements IDisposable

    - by Ryan ONeill
    I have an interface (IDbAccess) for a database access class so that I can unit test it using Unity. It all works fine in Unity and now I want to make the concrete database class implement IDisposable so that it closes the db connections. My problem is that Unity does not understand that my concrete class is disposable because the interface (IDbAccess) cannot implement another interface. So how can I write code like this (pseudo code) so that Unity is aware that it needs to dispose the class as soon as I am done? Using var MyDbAccessInstance = Unity.Resolve<IDbAccess> { } Thanks Ryan

  • More issues with IntelliJ 9.0.1 "Hello World" in Scala - Predef version 5.0 vs 4.1

    - by Alex R
    Any ideas what could cause this? Scala signature Predef has wrong version Expected 5.0 found: 4.1 in .... scala-library.jar I tried both versions 2.7.6 and 2.8 RC1 of scala-*.jar, the result was the same. JDK is 1.6.u20. UPDATE Today uninstalled IntelliJ 9.0.1, and installed 9.0.2 Early Availability, with the 4/14 stable version of the Scala plug-in. Then I setup a project from scratch through the wizards: new project from scratch JDK is 1.6.u20 accept the default (project) instead of global / module accept the download of Scala 2.8.0beta1 into project's lib folder Created a new class: object hello { def main(args: Array[String]) { println("hello: " + args); } } For my efforts, I now have a brand-new error :) Here it is: Scalac internal error: class java.lang.ClassNotFoundException [java.net.URLClassLoader$1.run(URLClassLoader.java:202), java.security.AccessController.doPrivileged(Native Method), java.net.URLClassLoader.findClass(URLClassLoader.java:190), java.lang.ClassLoader.loadClass(ClassLoader.java:307), sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301), java.lang.ClassLoader.loadClass(ClassLoader.java:248), java.lang.Class.forName0(Native Method), java.lang.Class.forName(Class.java:169), org.jetbrains.plugins.scala.compiler.rt.ScalacRunner.main(ScalacRunner.java:72)] Thanks

  • Convert a byte array to a class containing a byte array in C#

    - by Mathijs
    I've got a C# function that converts a byte array to a class, given it's type: IntPtr buffer = Marshal.AllocHGlobal(rawsize); Marshal.Copy(data, 0, buffer, rawsize); object result = Marshal.PtrToStructure(buffer, type); Marshal.FreeHGlobal(buffer); I use sequential structs: [StructLayout(LayoutKind.Sequential)] public new class PacketFormat : Packet.PacketFormat { } This worked fine, until I tried to convert to a struct/class containing a byte array. [StructLayout(LayoutKind.Sequential)] public new class PacketFormat : Packet.PacketFormat { public byte header; public byte[] data = new byte[256]; } Marshal.SizeOf(type) returns 16, which is too low (should be 257) and causes Marshal.PtrToStructure to fail with the following error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. I'm guessing that using a fixed array would be a solution, but can it also be done without having to resort to unsafe code?

  • Can no longer deploy to Amazon AWS using VS 2010

    - by KevinDeus
    Did something change on Amazon recently? I'm trying to redeploy to my Amazon instance, and the "Publish to Amazon Cloudformation" plugin for VS 2010 no longer appears to update my instance. It tells me that upload is successful, but my instance does not appear to be updating on Amazon I've tried disabling all my instances and using the tool to create a new instance , but no luck. I do see that the URL of the deployed application (which looks like this: http://c2-107-20-11-27.compute-1.amazonaws.com) does not appear to match up with the public IP of my instance on Amazon. (even when it creates a new one) This seems to indicate that something might be broken. any clues? (btw, whenever the Amazon VS2010 Plugin creates a new instance, I am sure to reconnect my elastic IP with the new instance)

  • PHP class constant string variable spanning over multiple lines

    - by ebae
    I want to have a string variable for a PHP class, which would be available to all methods. However, this variable is quite long, so I want to separate it into multiple lines. For example, $variable = "line 1" . "line 2" . "line 3"; But above doesn't work. I tried EOD, but EOD is not allowed within class. And when I declare it outside the class, I can't access the variable from within the class. What is the best way?

  • OpenVZ vs Xen, how much difference in performance?

    - by Aleksandr Levchuk
    There is a Xen vs. KVM in performance question on ServerFault. What will be the performance difference if the choice is between Xen and OpenVZ? How is it best to measure? Some may say "you're comparing apples and oranges" but I have to choose one of the two and it needs to be wise choice. Performance is most important to us. We may switching to Xen from OpenVZ because Xen is more ubiquitous but only if performance difference is not significant. In January 2011 I'm thinking of doing a head to head performance comparison - here is my project proposal to our Bioinformatics facility director.

  • design business class for unit test

    - by Mauro Destro
    I'm trying to clean my code to make it unit-testable. I know that unit tests must be created while coding but... I have to do it now, with code completed. My business class is full of methods with a similar implementation like: var rep=new NHrepository<ModelClass1>(Session); rep.Where(x=>x.Field1==1).ToList(); first error (from my point of view) is that I don't have to use "new" but instead use DI and add in the ctor parameters a INHrepository modelClass1Repository. If in my class I have two or more repository of different model class? Each must be in the ctor? Or probably business class is not build with SeparationOfConcern principle?

  • Color Profiles in Windows 7 vs. XP

    - by flxkid
    I have a Brother Color Laser Printer and an HP 8150DN. I have a local Windows 7 Pro machine that I do graphics work on. I created a letterhead that when printed from my machine looks dark and rich on either the mono HP or the color Brother laser. I take this same letterhead, and move it onto our network for use by our users which are all on XP. Then they print the same file, it is washed out on either printer. I've confirmed that the printer settings we're using are identical. I've confirmed that its not related to the program or even specifically to the letterhead. I can duplicate this with other files too. I'm down to XP vs Windows 7 being the issue. I'm fairly certain now that color profiles are involved. I have no clue how to fix it though. Any suggestions would be much appreciated.

  • What is the most basic class that inherits ICollection<T>

    - by Martin Neal
    I need a generic collection class which I can add to, and enumerate over. Since ICollection<T> inherits from IEnumerable<T>, the class really just needs to inherit from ICollection<T>. Is there a simple generic class in the BCL that just inherits ICollection<T>? If not, then what class comes closest? I would guess List<T> which is what I've been using. Is there anything better (by which I mean [smaller/faster/simpler])? Thanks in advance!

  • Problem with LINQ Generated class and IEnumerable to Excel

    - by mehmet6parmak
    Hi all, I wrote a method which exports values to excel file from an IEnumerable parameter. Method worked fine for my little test class and i was happy till i test my method with a LINQ class. Method: public static void IEnumerableToExcel<T>(IEnumerable<T> data, HttpResponse Response) { Response.Clear(); Response.ContentEncoding = System.Text.Encoding.Default; Response.Charset = "windows-1254"; // set MIME type to be Excel file. Response.ContentType = "application/vnd.ms-excel;charset=windows-1254"; // add a header to response to force download (specifying filename) Response.AddHeader("Content-Disposition", "attachment;filename=\"ResultFile.xls\""); Type typeOfT = typeof(T); List<string> result = new List<string>(); FieldInfo[] fields = typeOfT.GetFields(); foreach (FieldInfo info in fields) { result.Add(info.Name); } Response.Write(String.Join("\t", result.ToArray()) + "\n"); foreach (T t in data) { result.Clear(); foreach (FieldInfo f in fields) result.Add((typeOfT).GetField(f.Name).GetValue(t).ToString()); Response.Write(String.Join("\t", result.ToArray()) + "\n"); } Response.End(); } My Little Test Class: public class Mehmet { public string FirstName; public string LastName; } Two Usage: Success: Mehmet newMehmet = new Mehmet(); newMehmet.FirstName = "Mehmet"; newMehmet.LastName = "Altiparmak"; List<Mehmet> list = new List<Mehmet>(); list.Add(newMehmet); DeveloperUtility.Export.IEnumerableToExcel<Mehmet>(list, Response); Fail: ExtranetDataContext db = new ExtranetDataContext(); DeveloperUtility.Export.IEnumerableToExcel<User>(db.Users, Response); Fail Reason: When the code reaches the code block used to get the fields of the template(T), it can not find any field for the LINQ Generated User class. For my weird class it works fine. Why? Thanks...

  • CoffeeScript Class Properties Within Nested Anonymous Functions

    - by Aric
    I'm just taking a look at CoffeeScript for the first time so bare with me if this is a dumb question. I'm familiar with the hidden pattern methodology however I'm still wrapping my head around object prototypes. I'm trying to create a basic class for controlling a section on my site. The problem I'm running into is losing defined class variables within a different scope. For example, the code below works fine and creates the properties within the object perfectly. However when I jump into a jQuery callback I lose all knowledge of the class variables storing some of the jQuery objects for multiple uses. Is there a way to grab them from within the callback function? class Session initBinds: -> @loginForm.bind 'ajax:success', (data, status, xhr) -> console.log("processed") return @loginForm.bind 'ajax:before', (xhr, settings) -> console.log @loader // need access to Session.loader return return init: -> @loginForm = $("form#login-form") @loader = $("img#login-loader") this.initBinds() return

  • JAXB marshals XML differently to OutputStream vs. StringWriter

    - by Andy
    I apologize if this has been answered, but the search terms I have been using (i.e. JAXB @XmlAttribute condensed or JAXB XML marshal to String different results) aren't coming up with anything. I am using JAXB to un/marshal objects annotated with @XmlElement and @XmlAttribute annotations. I have a formatter class which provides two methods -- one wraps the marshal method and accepts the object to marshal and an OutputStream, the other just accepts the object and returns the XML output as a String. Unfortunately, these methods do not provide the same output for the same objects. When marshaling to a file, simple object fields internally marked with @XmlAttribute are printed as: <element value="VALUE"></element> while when marshaling to a String, they are: <element value="VALUE"/> I would prefer the second format for both cases, but I am curious as to how to control the difference, and would settle for them being the same regardless. I even created one static marshaller that both methods use to eliminate different instance values. The formatting code follows: /** Marker interface for classes which are listed in jaxb.index */ public interface Marshalable {} /** Local exception class */ public class XMLMarshalException extends BaseException {} /** Class which un/marshals objects to XML */ public class XmlFormatter { private static Marshaller marshaller = null; private static Unmarshaller unmarshaller = null; static { try { JAXBContext context = JAXBContext.newInstance("path.to.package"); marshaller = context.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8"); unmarshaller = context.createUnmarshaller(); } catch (JAXBException e) { throw new RuntimeException("There was a problem creating a JAXBContext object for formatting the object to XML."); } } public void marshal(Marshalable obj, OutputStream os) throws XMLMarshalException { try { marshaller.marshal(obj, os); } catch (JAXBException jaxbe) { throw new XMLMarshalException(jaxbe); } } public String marshalToString(Marshalable obj) throws XMLMarshalException { try { StringWriter sw = new StringWriter(); marshaller.marshal(obj, sw); } catch (JAXBException jaxbe) { throw new XMLMarshalException(jaxbe); } } } /** Example data */ @XmlType @XmlAccessorType(XmlAccessType.FIELD) public class Data { @XmlAttribute(name = value) private String internalString; } /** Example POJO */ @XmlType @XmlRootElement(namespace = "project/schema") @XmlAccessorType(XmlAccessType.FIELD) public class Container implements Marshalable { @XmlElement(required = false, nillable = true) private int number; @XmlElement(required = false, nillable = true) private String word; @XmlElement(required = false, nillable = true) private Data data; } The result of calling marshal(container, new FileOutputStream("output.xml")) and marshalToString(container) are as follows: Output to file <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns2:container xmlns:ns2="project/schema"> <number>1</number> <word>stackoverflow</word> <data value="This is internal"></data> </ns2:container> and Output to String <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <ns2:container xmlns:ns2="project/schema"> <number>1</number> <word>stackoverflow</word> <data value="This is internal"/> </ns2:container>

  • PHP: How to cast object to inherited class?

    - by andreyvlru
    I'd like to inherit PDOStatement class and use it in my website scripts. But I am frustrated how to get required object. PDO::query returns only direct PDOStatement object and looks like there are no other method to create PDOStatement object or inherited class. Initially i thought to move PDOStatement object to constructor of inherit class Something like that: $stmt = PDO -> query("select * from messages"); $messageCollection = new Messaging_Collection($stmt); But how to make instance of PDOStatement to inherited object (Messaging_Collection). It is a big question for me. class Messaging_Collection extends PDOStatement { public function __construct(PDOStatement $stmt) { //there i should to transform $stmt to $this // direct $this = $stmt is not possible // is there other right way? }

  • Cucumber/Webrat: follow link by CSS class?

    - by Joe
    Hello there, is it possible to follow a link by it's class name instead of the id, text or title? Given I have (haha, cucumber insider he?) the following html code: <div id="some_information_container"> <a href="edit" class="edit_button">Translation here</a> </div> I do not want to match by text because I'd have to care about the translation values in my tests I want to have my buttons look all the same style, so I will use the CSS class. I don't want to assign a id to every single link, because some of them are perfectly identified through the container and the link class Is there anything I missed in Cucumber/Webrat? Or do you have some advices to solve this in a better way? Thanks for your help and best regards, Joe edit: I found an interesting discussion going on about this topic right here - seems to remain an open issue for now. Do you have any other solutions for this?
