• Setting the initial value of a property when using DataContractSerializer

  - by Eric

  If I am serializing and later deserializing a class using DataContractSerializer how can I control the initial values of properties that were not serialized? Consider the Person class below. Its data contract is set to serialize the FirstName and LastName properties but not the IsNew property. I want IsNew to initialize to TRUE whether a new Person is being instantiate as a new instance or being deserialized from a file. This is easy to do through the constructor, but as I understand it DataContractSerializer does not call the constructor as they could require parameters. [DataContract(Name="Person")] public class Person { [DataMember(Name="FirstName")] public string FirstName { get; set; } [DataMember(Name = "LastName")] public string LastName { get; set; } public bool IsNew { get; set; } public Person(string first, string last) { this.FirstName = first; this.LastName = last; this.IsNew = true; } }

• Multiple key/value pairs in HTTP POST where key is the same name

  - by randombits

  I'm working on an API that accepts data from remote clients, some of which where the key in an HTTP POST almost functions as an array. In english what this means is say I have a resource on my server called "class". A class in this sense, is the type a student sits in and a teacher educates in. When the user submits an HTTP POST to create a new class for their application, a lot of the key value pairs look like: student_name: Bob Smith student_name: Jane Smith student_name: Chris Smith What's the best way to handle this on both the client side (let's say the client is cURL or ActiveResource, whatever..) and what's a decent way of handling this on the server-side if my server is a Ruby on Rails app? Need a way to allow for multiple keys with the same name and without any namespace clashing or loss of data.

• Include code in ASP.net

  - by Tom Gullen

  I've got an ASP.net file, and I'm trying to include dynamic code which was easy in classic ASP. Here is what I have tried so far: <%@ Register TagPrefix="TagPre" TagName="header" Src="alg/classes.aspx"%> and <!--#include file="alg/classes.aspx"--> But neither of these seem to work.

• How do I migrate a ManyToOne to a ManyToMany relationship in Hibernate?

  - by spderosso

  I have a instance field of a class X that is mapped using Hibernate as a Many to One relationship. E.g: public class X{ ... @ManyToOne(optional=false) private Y iField; ... } That is correctly working with a particular schema. I know want to change this instance field iField to a List and a Many to Many relationship. public class X{ ... @ManyToMany(optional=false) private List<Y> iField; ... } What steps should I follow? Do I have to change the schema? in which way? In case you need more info let me know. Thanks!

• Inheritance Problem in Perl OOP

  - by Sam

  Hello, I have a sub class that calls a method from a super class. and the method in the super class use a method that is defined in the super class as asbstract(not really abstract) but implemented in the sub class. for example: package BaseClass; sub new { } sub method1 { return someAbstractMethod(); } sub someAbtsractMethod { die "oops, this is an abstract method that should be implemented in a subclass" ; } 1; package SubClass; sub new { } sub someAbtsractMethod { print "now we implement the asbtract method"; } 1; now when I do: $sub = new SubClass(); $sub-method1(); It calls the abstract message and i get the specified error message. if I took off the abstractmethod from the super class and just leave the implementation in the subclass, It does not recognize the method and I get subroutine abstractmethod not found error.

• How are java.lang.Object's protected methods protected from subclasses?

  - by Adrian Lang

  The keyword protected grants access to classes in the same package and subclasses (http://java.sun.com/docs/books/tutorial/java/javaOO/accesscontrol.html). Now, every class has java.lang.Object as superclass (http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Object.html). Hence I conclude that every class may access java.lang.Object's methods even if they are protected. Take a look at the following example: public class Testclass { public Object getOne() throws CloneNotSupportedException { return this.clone(); } public Object getTwo() throws CloneNotSupportedException { return ((Object) this).clone(); } } While getOne() compiles fine, getTwo() gives Testclass.java:6: clone() has protected access in java.lang.Object return ((Object) this).clone(); I neither understand why getTwo() doesn't compile nor what's the difference (regarding the access of java.lang.Objects members) with getOne().

• Javascript: addClassName if input is checked and removeClassName if it was un-checked

  - by BoDiE2003

  Im trying to select all the li tags of the document and check if it hasClassName('yes') so if it has, it will remove it. But im having a TypeError: Object [object HTMLLIElement], has no method 'hasClassName' error. This is the DOM method: document.observe("dom:loaded", function() { $(document.body).select('input').each(function(element) { element.observe('click', function() { init(); }); init(); }); }); The previous code will take the init fuction and check the if there are checked inputs and add them the 'yes' class name, but if I un-check those inputs, the class remains. This is the funcion that Im trying to do dynamic (add and remove class 'yes'); function init() { $(document.body).select('input').each(function(element) { if (element.checked) { element.up('li').addClassName('yes'); } if ($(document.body).select('li').hasClassName('yes')) { element.removeClassName('yes'); } }) } Can you help me solving the last part of this function, so the removeclassname method will work? Thank you

• Using attr_accessible in a join model with has_many :through relationship

  - by Paulo Oliveira

  I have a USER that creates a COMPANY and become an EMPLOYEE in the process. The employees table has an :user_id and a :company_id. class User has_many :employees has_many :companies, :through => :employees class Employee belongs_to :user belongs_to :company attr_accessible :active class Company has_many :employees has_many :users, :through => employees Pretty basic. But here's the thing, the resource EMPLOYEE has other attributes than its foreign keys, like the boolean :active. I would like to use attr_accessible, but this causes some problems. The attribute :user_id is set right, but :company_id is nil. @user.companies << Company.new(...) Employee id:1 user_id:1 company_id:nil So my question is: if :user_id is set right, despite it is not an attr_accessible, why :company_id isn't set right just the same? It shouldn't be an attr_accessible. I'm using Rails 3.0.8, and have also tested with 3.0.7.

• Setting a value into a object using reflection

  - by marionmaiden

  Hello I have an object that has a lot of attributes, each one with it's getter and setter. Each attribute has a non primitive type, that I don't know at runtime. For example, what I have is this: public class a{ private typeA attr1; private typeB attr2; public typeA getAttr1(){ return attr1; } public typeB getAttr2(){ return attr2; } public void setAttr1(typeA at){ attr1 = at; } public void setAttr2(typeB at){ attr2 = at; } } public class typeA{ public typeA(){ // doesn't matter } } public class typeB{ public typeB(){ // doesn't matter } } So, using reflection, I obtained the setter method for an attribute. Setting a value in the standard way is something like this: a test = new a(); a.setAttr1(new typeA()); But how can I do this using reflection? I already got the setAttr1() method using reflection, but I don't know how to create a new typeA object to be inserted in the setter.

• How to get physical partition name from iSCSI details on Windows?

  - by Barry Kelly

  I've got a piece of software that needs the name of a partition in \Device\Harddisk2\Partition1 style, as shown e.g. in WinObj. I want to get this partition name from details of the iSCSI connection that underlies the partition. The trouble is that disk order is not fixed - depending on what devices are connected and initialized in what order, it can move around. So suppose I have the portal name (DNS of the iSCSI target), target IQN, etc. I'd like to somehow discover which volumes in the system relate to it, in an automated fashion. I can write some PowerShell WMI queries that get somewhat close to the desired info: PS> get-wmiobject -class Win32_DiskPartition NumberOfBlocks : 204800 BootPartition : True Name : Disk #0, Partition #0 PrimaryPartition : True Size : 104857600 Index : 0 ... From the Name here, I think I can fabricate the corresponding name by adding 1 to the partition number: \Device\Harddisk0\Partition1 - Partition0 appears to be a fake partition mapping to the whole disk. But the above doesn't have enough information to map to the underlying physical device, unless I take a guess based on exact size matching. I can get some info on SCSI devices, but it's not helpful in joining things up (iSCSI target is Nexenta/Solaris COMSTAR): PS> get-wmiobject -class Win32_SCSIControllerDevice __GENUS : 2 __CLASS : Win32_SCSIControllerDevice ... Antecedent : \\COBRA\root\cimv2:Win32_SCSIController.DeviceID="ROOT\\ISCSIPRT\\0000" Dependent : \\COBRA\root\cimv2:Win32_PnPEntity.DeviceID="SCSI\\DISK&VEN_NEXENTA&PROD_COMSTAR... Similarly, I can run queries like these: PS> get-wmiobject -namespace ROOT\WMI -class MSiSCSIInitiator_TargetClass PS> get-wmiobject -namespace ROOT\WMI -class MSiSCSIInitiator_PersistentDevices These guys return information relating to my iSCSI target name and the GUID volume name respectively (a volume name like \\?\Volume{guid-goes-here}), but the GUID volume name is no good to me, and there doesn't appear to be a reliable correspondence between the target name and the volume that I can join on. I simply can't find an easy way of getting from an IQN (e.g. iqn.1992-01.com.example:storage:diskarrays-sn-a8675309) to physical partitions mapped from that target. The way I do it by hand? I start Disk Management, and look for a partition of the correct size, verify that its driver says NEXENTA COMSTAR, and look at the disk number. But even this is unreliable if I have multiple iSCSI volumes of the exact same size. Any suggestions?

• Where should Nhibernate IPostInsertEventListener go in the 3 tier architecture

  - by Quintin Par

  I have a IPostInsertEventListener implementation like public class NHibernateEventListener : IPostInsertEventListener, IPostUpdateEventListener which catches some entity inserts and does an additional insert to another table for ETL. Essentially it requires references to the Nhibernate, Domain entity and Repository<> Now where do I go about adding this class? If I add it to ApplicationServices I’ll end up referencing Nhibernate at that layer. If I add this to the Data layer, I’ll have to reference Domain (circular). How do I go implementing this class with S#arp principles? Any thoughts?

• Drag and Drop text - What am I missing?

  - by Harvey

  I am trying to add drag-and-drop text to my Doc-View App. I added the COleDropTarget variable to the view class, registered it in OnCreate(). I added OnDragEnter(), OnDragOver(), OnDragLeave() and OnDrop() to that class as virtual overrides, but none of them are ever called. I previously had added m_pMainWnd-DragAcceptFiles(TRUE); to my App class. I tried commenting out that statement, but no affect. I tried using Spy++ to see where the messages go while I do a drag, but it logs nothing at all while I am dragging the text around in the App. What do I need? Or what else can I try, to narrow down the problem? TIA, Harvey

• C++ 'mutable' keyword

  - by Rob

  A while ago I came across some code that marked a member variable of a class with the 'mutable' keyword. As far as I can see it simply allows you to modify a variable in a 'const' method: class Foo { private: mutable bool done_; public: void doSomething() const { ...; done_ = true; } }; Is this the only use of this keyword or is there more to it than meets the eye? I have since used this technique in a class, marking a boost::mutex as mutable allowing const functions to lock it for thread-safety reasons, but, to be honest, it feels like a bit of a hack.

• WPF: change DataTemples according to Value

  - by Kave

  I have a class called Cell with two properties. One is called Value of type int? And the other is called Candidates of type ObservableCollection during the initialization I am utilizing a DataTemplateSelector to choose between two datatemplates for two different scenarios. If the Value property has a value then template A should be used to present the Cell class. However if the Value property is null Then template B should be used to present the Cell class. While this works perfectly fine during the initialization however during the runtime the templates don't change any more when the value of the Value property actually changes. Is the approach of using DataTemplateSelector the wrong approach to change DataTemplates dynamically? What would you recommend I should do? Many thanks,

• Interface naming in Java

  - by Allain Lalonde

  Most OO languages prefix their interface names with a capital I, why does Java not do this? What was the rationale for not following this convention? To demonstrate what I mean, if I wanted to have a User interface and a User implementation I'd have two choices in Java: Class = User, Interface = UserInterface Class = UserImpl, Interface = User Where in most languages: Class = User, Interface = IUser Now, you might argue that you could always pick a most descriptive name for the user implementation and the problem goes away, but Java's pushing a POJO approach to things and most IOC containers use DynamicProxies extensively. These two things together mean that you'll have lots of interfaces with a single POJO implementation. So, I guess my question boils down to: "Is it worth following the broader Interface naming convention especially in light of where Java Frameworks seem to be heading?"

• Apply Alloy UI 1.5 datepicker to multiple instances

  - by MyTitle

  I want to create Alloy UI datapickers on multiple form fields: <div id="date_1_wrapper"> <input type="text" class="datepick" id="date_1" /> </div> <div id="date_2_wrapper"> <input type="text" class="datepick" id="date_2" /> </div> Using JQuery I can do it using following code: $('.datepick').each(function(){ $(this).datepicker(); }); But how to achieve same functionality in Alloy UI? For now I use following code, but this code apply DatePickers by ID, not by CSS class in loop: AUI().use( 'aui-datepicker', function(A) { new A.DatePicker ( { calendar: { dateFormat: '%d/%m/%Y' }, trigger: '#date_1' } ).render('#date_1_wrapper'); new A.DatePicker( { calendar: { dateFormat: '%d/%m/% }, trigger: '#date_2' } ).render('#date_2_wrapper'); } ); I think it this code can be used in beginning, but how to deal with input's and div's ID's? (A.all('.datepcik').each(function() {)

• Tool(s) to lower the friction of programming against Interfaces in Visual Studio C#?

  - by John

  Hi I am a relatively new user of Visual Studio and I am trying "program against interfaces". I can see that when I create a class I can "Extract Interface" from the Refactor menu but you seem to only get one shot at this. ie. If I add a read only property FullName to my Customer class I would like to be able to right click and update the interface. At the moment I can only create a new interface from the Refactor menu. I want to update the interface I have already created not create new one. So the kind of tool I would be looking for would display check boxes for all valid members of the class with those already in the interface checked. It would also be handy to be able to to create the initial interface file in a different project (in the same solution), and for the tool to keep track of this. Does such a tool / add in / menu item exist (other than Ctrl C / V)? Thanks, John
