  • How to use DataContractSerializer to create xml with tag names that match my known types

    - by mezoid
    I have the following data contract: [CollectionDataContract(Name="MyStuff")] public class MyStuff : Collection<object> {} [DataContract(Name = "Type1")] [KnownType(typeof(Type1))] public class Type1 { [DataMember(Name = "memberId")] public int Id { get; set; } } [DataContract(Name = "Type2")] [KnownType(typeof(Type2))] public class Type2 { [DataMember(Name = "memberId")] public int Id { get; set; } } Which I serialize to xml as follows: MyStuff pm = new MyStuff(); Type1 t1 = new Type1 { Id = 111 }; Type2 t2 = new Type2 { Id = 222 }; pm.Add(t1); pm.Add(t2); string xml; StringBuilder serialXML = new StringBuilder(); DataContractSerializer dcSerializer = new DataContractSerializer(typeof(MyStuff)); using (XmlWriter xWriter = XmlWriter.Create(serialXML)) { dcSerializer.WriteObject(xWriter, pm); xWriter.Flush(); xml = serialXML.ToString(); } The resultant xml string looks like this: <?xml version="1.0" encoding="utf-16"?> <MyStuff xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/"> <anyType i:type="Type1"> <memberId>111</memberId> </anyType> <anyType i:type="Type2"> <memberId>222</memberId> </anyType> </MyStuff> Does anyone know how I can get it to instead use the name of my known types rather than anyType in the xml tag? I'm wanting it to look like this: <?xml version="1.0" encoding="utf-16"?> <MyStuff xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/"> <Type1> <memberId>111</memberId> </Type1> <Type2> <memberId>222</memberId> </Type2> </MyStuff>

  • Perl Test::More, get stdout

    - by Mike
    Is there a way inside a Perl test case using Test::More to get the program's stdout For instance, if I do use Test::More; ok(foo()); #in the code I am testing sub foo() { print "hello" } "hello" will not be visible. I would like to see it. edit I know I can use diag(), however this would not work if the print is inside the code I am testing

  • How do I ADD an Attribute to the Root Element in XML using XSLT?

    - by kunjaan
    I want to match a root Element “FOO” and perform the transformation (add a version attribute) to it leaving the rest as it is. The Transformation I have so far looks like this: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://schemas.foo.com/fooNameSpace"> <xsl:template match="//FOO"> <xsl:choose> <xsl:when test="@version"> <xsl:apply-templates select="node()|@*" /> </xsl:when> <xsl:otherwise> <FOO> <xsl:attribute name="version">1</xsl:attribute> <xsl:apply-templates select="node()|@*" /> </FOO> </xsl:otherwise> </xsl:choose> </xsl:template> However this does not perform any transformation. It doesn't even detect the element. So I need to do add the namespace in order to make it work: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fd="http://schemas.foo.com/fooNameSpace"> <xsl:template match="//fd:FOO"> … But this attaches a namespace attribute to the FOO element as well as other elements: <FOO xmlns:fd="http://schemas.foo.com/fooNameSpace" version="1" id="fooid"> <BAR xmlns="http://schemas.foo.com/fooNameSpace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> Is there a way to say that the element is using the default namespace? Can we match and add elements in the default name space? Here is the original XML: <?xml version="1.0" encoding="UTF-8"?> <FOO xmlns="http://schemas.foo.com/fooNameSpace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <BAR> <Attribute name="HEIGHT">2067</Attribute> </BAR> </FOO>

    Hello, I have a schema schema1 in a postgres database A. I want to have a duplicate of this schema (model + data) in database B under the name schema2. What are my options ? I currently : * dump schema1 from database A * sed my way through schema renaming in the dump : schema1 becomes schema2 * restore schema2 in database B but I am looking for a more efficient procedure. For instance, via direct file operations on postgres binary files. Thanks for your help Jerome Wagner

  • IoC/DI in the face of winforms and other generated code

    - by Kaleb Pederson
    When using dependency injection (DI) and inversion of control (IoC) objects will typically have a constructor that accepts the set of dependencies required for the object to function properly. For example, if I have a form that requires a service to populate a combo box you might see something like this: // my files public interface IDataService { IList<MyData> GetData(); } public interface IComboDataService { IList<MyComboData> GetComboData(); } public partial class PopulatedForm : BaseForm { private IDataService service; public PopulatedForm(IDataService service) { //... InitializeComponent(); } } This works fine at the top level, I just use my IoC container to resolve the dependencies: var form = ioc.Resolve<PopulatedForm>(); But in the face of generated code, this gets harder. In winforms a second file composing the rest of the partial class is generated. This file references other components, such as custom controls, and uses no-args constructors to create such controls: // generated file: PopulatedForm.Designer.cs public partial class PopulatedForm { private void InitializeComponent() { this.customComboBox = new UserCreatedComboBox(); // customComboBox has an IComboDataService dependency } } Since this is generated code, I can't pass in the dependencies and there's no easy way to have my IoC container automatically inject all the dependencies. One solution is to pass in the dependencies of each child component to PopulatedForm even though it may not need them directly, such as with the IComboDataService required by the UserCreatedComboBox. I then have the responsibility to make sure that the dependencies are provided through various properties or setter methods. Then, my PopulatedForm constructor might look as follows: public PopulatedForm(IDataService service, IComboDataService comboDataService) { this.service = service; InitializeComponent(); this.customComboBox.ComboDataService = comboDataService; } Another possible solution is to have the no-args constructor to do the necessary resolution: public class UserCreatedComboBox { private IComboDataService comboDataService; public UserCreatedComboBox() { if (!DesignMode && IoC.Instance != null) { comboDataService = Ioc.Instance.Resolve<IComboDataService>(); } } } Neither solution is particularly good. What patterns and alternatives are available to more capably handle dependency-injection in the face of generated code? I'd love to see both general solutions, such as patterns, and ones specific to C#, Winforms, and Autofac.

  • Which MySQL Frontend shows foreign rows?

    - by Jeremy Rudd
    I once came across a MySQL Frontend app that displayed foreign linked rows within the parent row, if for instance the Events table has a foreign key to the Students table: Student ID Name DOB -- ---- --------- [+] 22 Bob 25-1-1984 [-] 21 Jane 25-1-1982 Event ID Student-ID Name Time -- ---------- ---- --------- 1 21 Event A 05:50 1 21 Event B 17:20 [+] 20 Jack 25-1-1980

  • Correct mapping for SHChangeNotify in JNA

    - by user389658
    This is syntax for SHChangeNotify function from MSDN: void SHChangeNotify( LONG wEventId, UINT uFlags, __in_opt LPCVOID dwItem1, __in_opt LPCVOID dwItem2 ); I've to write its Java counterpart in Java Native Access [JNA], but this declaration seems to be wrong: public interface Shell32 extends com.sun.jna.platform.win32.Shell32 { public Shell32 INSTANCE = (Shell32) Native.loadLibrary(Shell32.class); void SHChangeNotify(long wEventId, int uFlags, Pointer dwItem1, Pointer dwItem2); } I got the following exception: Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'SHChangeNotify' Any idea how to write it correctly?

  • How to 'assign' a value to an output reg in Verilog?

    - by Rafael Almeida
    ( insert really basic question disclaimer here ) More specifically, I have the following declaration: output reg icache_ram_rw And in some point of the code I need to put the zero value in this reg. Here's what I've tried and the outcomes: assign icache_ram_rw = 1'b0; ( declarative lvalue or port sink reg icache_ram_rw must be a wire ) icache_ram_rw <= 1'b0; ( instance gate/name for type "icache_ram_rw" expected - <= read ) How do I do it after all?!

  • quick question about memory management in AS3

    - by TheDarkIn1978
    the following method will be called many times. i'm concerned the continuous call for new rectangles will add potentially unnecessary memory consumption, or is the memory used to produce the previous rectangle released/overwritten to accommodate another rectangle since it is assigned to the same instance variable? private function onDrag(evt:MouseEvent):void { this.startDrag(false, dragBounds()); } private function dragBounds():Rectangle { var stagebounds = new Rectangle(0 - swatchRect.x, 0 - swatchRect.y, stage.stageWidth - swatchRect.width, stage.stageHeight - swatchRect.height); return stagebounds; }

  • Naming convention when casually referring to methods in Java

    - by polygenelubricants
    Is there a Java convention to refer to methods, static and otherwise, any specific one or the whole overload, etc? e.g. String.valueOf - referring to all overloads of static valueOf String.valueOf(char) - specific overload, formal parameter name omittable? String.split - looks like a static method, but actually an instance method Maybe aString.split is the convention? String#split - I've seen this HTML anchor form too, which I guess is javadoc-influenced Is there an authoritative recommendation on how to clearly refer to these things?

  • will_paginate with named_scopes

    - by Lowgain
    I'm using will_paginate for pagination, which has been working well so far, except for this one thing. If I try to paginate a scope, for instance class User < ActiveRecord::Base named_scope :scope, lambda { etc } end User.scope.paginate({:page => params[:page], :per_page => 10}) That will tell me paginate is an undefined method. I'd rather not have to use a second solution for only this scope, is there something I can do here?

  • How To Create Per-Request Singleton in Pylons?

    - by dave mankoff
    In our Pylons based web-app, we're creating a class that essentially provides some logging functionality. We need a new instance of this class for each http request that comes in, but only one per request. What is the proper way to go about this? Should we just create the object in middleware and store in in request.environ? Is there a more appropriate way to go about this?

  • Is there a fast way to jump to element using XMLReader?

    - by Derk
    I am using XMLReader to read a large XML file with about 1 million elements on the level I am reading from. However, I've calculated it will take over 10 seconds when I jump to -for instance- element 500.000 using XMLReader::next ([ string $localname ] ) or XMLReader::read ( void ) This is not very usable. Is there a faster way to do this?

  • How can I determine which taskbar application/windows are requesting user attention

    - by Frederic
    I'd like to know how to get a list of the windows requiring user attention from the Windows taskbar. Windows requiring attention appear with a flashing orange color within the Windows taskbar. Un-focused MSN Messenger conversation windows are a good example of this behavior: they turn orange as soon as a remote user sends an instance message. My code targets the Windows 7 platform, but working on older Windows OS would be nice too.

  • How to change default conjunction with Lucene MultiFieldQueryParser

    - by Luke H
    I have some code using Lucene that leaves the default conjunction operator as OR, and I want to change it to AND. Some of the code just uses a plain QueryParser, and that's fine - I can just call setDefaultOperator on those instances. Unfortunately, in one place the code uses a MultiFieldQueryParser, and calls the static "parse" method (taking String, String[], BooleanClause.Occur[], Analyzer), so it seems that setDefaultOperator can't help, because it's an instance method. Is there a way to keep using the same parser but have the default conjunction changed?
