  • Problem in serializing

    - by Harun
    Hello Guyz, Presently I need to serialize one of my object which contains more my own classes object. But the problem is I dont want to save it in a file and then retrieve it into memory stream. Is there any way to directly serialize my object into stream. I used BinaryFormatter for seializing. First I used a MemoryStream directly to take serialize output but it is giving error at time of deserialization. But later when I serialize it with a file then close it and again reopen it , it works perfectly. But I want to take it direct into stream because in my program I need to do it frequently to pass it into network client. And using file repeatedly might slow down my software. Hope I clear my problem. Any Sugetion ?

  • Get property name from class

    - by Polaris
    I need property name in my app and I use next code to get it string PropertyName =SomeClass.GetType().GetProperty("Category").Name; But I think that is bad idea. Because I use web service classes and I dont know when property names can be changed. This code give me exception only in runtime. But if I write something like this SomeClassInstance.Property.GetProperyName i get exception in moment of compilation and repair this problem. Is it possible to get property name dynamically?

  • Hibernate Annotation for Entity existing in more than 1 catalog

    - by user286395
    I have a Person entity mapped by Hibernate to a database table in a database catalog "Active". After a period of time, records in this database table in the "Active" catalog are archived/moved to an exact copy of the table in a database Catalog "History". I have the need to retrieve from both the Active and History Catalogs. Is there a better way to model this with Hibernate annotations than making an abstract class that 2 classes extend from. This is what I have now. @MappedSuperclass public abstract class Person { @Id private Integer id; private String name; } @Entity @Table(name="Person", catalog="Active") public class PersonActive extends Person { } @Entity @Table(name="Person", catalog="History") public class PersonHistory extends Person { }

  • sqlsrv_connect() not found..

    - by Gushiken
    Hey, I recently am working on an projekt that uses the "SQL Server Driver for PHP", i wanted to upgrade the existing driver to the new version (2.0), because I need some of the functions that have been implemented there. Now i replaced the old .dll in the php/ext directory and restarted the webserver. But now i recieve the following error: Fatal error: Call to undefined function sqlsrv_connect() in E:\ProjekteExtern\hades_apl\classes\sql\sqlsrv.class.php on line 34 But if i run phpinfo();, sqlsrv shows up, in the same way as the previous version did. Does anybody know this error or has an idea how to solve this problem? Thanks in advance :) Gushiken

  • Returning EF entities using WCF - Read only web service / public API

    - by alex
    I'm currently migrating an application from Linq-to-SQL & ASP.net Web Services (asmx) to Entity Framework and WCF. My question is, I have a bunch of POCO classes which i have xml mapping files for (for the linq to sql) I've replaced my linq to sql with an entity framework data model I've got an interface - something like IService - that has all the methods on it that i need my service to implement - for example: Product[] GetProductsByKeyword(string keyword); In the above case, Product is a POCO. I now have them as entities within my ef data model - i'm using .net 4, and could take advantage of poco support, but don't really see the need - This service is strictly read only. What's the best way of returning entities in my WCF service? I want it to support other client platforms, not just .net (so php guys could use it)

  • Json Object to a Multidimensional C# Array?

    - by Nick Brooks
    Is there a way to convert a Json Object to a Multidimensional C# Array? I know it might be impractical but I can't be bothered to write classes and then deserialize the strings into them. List<string> ohyeah = (List<string>)JsonConvert.DeserializeObject(g.CommToken); That returns an Invalid Cast exception! Example: {"method":"getCommunicationToken","header":{"uuid":"9B39AAB0-49A6-AC7A-BA74-DE9DA66C62B7","clientRevision":"20100323.02","session":"c0d3e8b5d661f74c68ad72af17aeb5a1","client":"gslite"},"parameters":{"secretKey":"d9b687fa10c927f102cde9c085f9377f"}} I need to get something like that : j["method"]; //This will equal to getCommunicationToken j["header"]["uuid"]; //This will equal to 9B39AAB0-49A6-AC7A-BA74-DE9DA66C62B7 I literally need to parse the json object into an array.

  • Is it possible to apply inheritance to a Singleton class?

    - by Bragaadeesh
    Hi, Today I faced one question in interview. Is it possible to apply inheritance concept on Singleton Classes. I said since the constructor is private, we cannot extend that Singleton class (can someone please validate this). Next thing he asked me is to apply inheritance on that Singleton class. So, I made the Singleton's constructor as protected thinking that child's constructor also has be protected. But I was wrong the child can have a modifier either equal to or higher than that. So, I asked him to give a real world example on such a case. He was not able to give me one and said that I cant ask questions and wanted me to tell whether this scenario is possible or not. I went kind of blank. My question here is, Is this possible? Even if its possible, what is the use of it? What real world scenario would demand such a use. Thanks

  • Is there any Android XML documentation?

    - by Eddified
    Is there any sort of xml reference? I found this which turned out to be invaluable for me http://groups.google.com/group/android-developers/msg/d334017d72909c79 but I can't figure out how I was supposed to know how to do that, had I not found that post. I know that the api reference has xml attributes listed for many of the classes... but what about xml tags? Where is it documented that I could build a shape using , , tags? I'd really like to know where I can find such documentation.

  • Windows service - supplying arguments in "path to executable"

    - by Jono
    I cannot figure out how to pass (constant) arguments into my Windows service when it is started. I'm using the standard .NET classes like ServiceBase to implement (and ServiceProcessInstaller and ServiceInstaller to install) my service. On the general tab of a Windows Service properties dialog box (once installed), there's a "Path to executable" in which I can see that some of the standard Windows services have command line arguments specified. System.ServiceProcess.ServiceBase.OnStart takes string[] args, which I presume would enable these arguments to be accessed from within .NET code. Are there some properties on ServiceProcessInstaller or ServiceInstaller that I can set to allow me to pass startup arguments to my own service, or does anyone know how it's supposed to be done?

  • Mysql maven jpa skeleton

    - by coubeatczech
    Hi, is there a skeleton for a project using mysql, some eclipse/top link with RESOURCE_LOCAL as connection type? Preferably using maven. I'm searching for it for hours and can't get running even the sipmlest exaple. So if you had it ready and running, please, post :-). Even something as simple as these two classes only. @Entity public class Message implements Serializable{ public Message() {} public Message(String s){ this.s = s; } @Id String s; public String getS(){ return s; } } public class App { static private EntityManagerFactory emf; static private EntityManager em; public static void main( String[] args ) { emf = Persistence.createEntityManagerFactory("persistence"); em = emf.createEntityManager(); Message m = new Message("abc"); em.persist(m); } }

  • Why isn't this simple test class's method inherited in Ruby?

    - by Kevin Bannister
    Consider this very simple logging class: class MockLog def self.log_stub_method(*args) args.each do |a| define_method "#{a}" do |msg| t = Time.now.strftime("%Y-%m-%d %H:%M:%S") $stderr.puts "[#{a.upcase}] \u00bb [#{t}] #{msg}" end end end log_stub_method :fatal, :error, :warn, :info, :debug end Let's add logging to all our classes: class Module def has_logging() class_eval { @log = MockLog.new def log self.class.instance_variable_get :@log end } end end Now, why doesn't this work? class Foo has_logging end Foo.new.log.nil? # => false, as expected class Bar < Foo end Bar.new.log.nil? # => true?! Why wasn't the `log` method inherited?

  • Unrecognized option: -o Could not create the Java virtual machine.

    - by Kerubu
    I've got an unusual build error when using Buildroot to create an image for my Phidget SBC. It's unusual because it occurs ONLY on my development laptop and NOT on my general use laptop even though I am using EXACTLY the same Builroot environment as published by Phidgets themselves. When I try to create my Buildroot image I get the following error when it attempts to compile GNU classpath: Making all in tools make[2]: Entering directory `/home/xxxx/buildroot_phidgetsbc/buildroot-phidgetsbc_1.0.4.20111028/output/build/classpath-0.98/tools' /bin/mkdir -p classes asm /bin/mkdir -p ../tools/generated/gnu/classpath/tools/gjdoc/expr java -classpath antlr.Tool -o ../tools/generated/gnu/classpath/tools/gjdoc/expr/ \ ./gnu/classpath/tools/gjdoc/expr/java-expression.g Unrecognized option: -o Could not create the Java virtual machine. make[2]: *** [tools.zip] Error 1 The only difference I can possibly thing of is the different Linux (Ubuntu) versions I am using on each laptop. Also I cannot find a -o option documented for Java and don't understand why it works on one laptop but not the other. Any suggestions would be helpful.

  • Should downcasting be avoided while using a class hierarchy in C++?

    - by neuviemeporte
    Let's say I'm writing an application which works with projects, and exposes different functionality depending on the type of the project. I have a hierarchy of classes for the different types of projects: class AbstractProject { }; class ProjectA : public AbstractProject { }; class ProjectB : public AbstractProject { }; class ProjectC : public AbstractProject { }; Now, I was planning to have an AbstractProject *_currentProject pointer as a member in the application's main class, pop up a dialog box on startup and based on the selection, do: _currentProject = new ProjectB(); // e.g. Later, I'll have to downcast the pointer to the specific type to utilize the functionality specific to different Project-s. Somehow this makes me feel uneasy. Is there a Better Way of doing this?

  • Maven easyb plugin java heap space settings?

    - by vinnu
    Hi, I attempted to change my heap size for maven easyb plugin http://www.easyb.org/maven-easyb-plugin/. In my easyb test I added standard code to print the heap size using the code Runtime.getFreeMemory() and Runtime.getTotalMemory(). I tried setting the MAVEN_OPTS=-Xmx1024m -Xms1024m and also set the maven opts in Maven surefire plugin. Now when I run the same class from the Junit I can see the getTotalMemory() displaying a number close 1Gig but the when the same classes are invoked from easyb plugin they do not reflect the memory size. Shouldn't there be a way of passing JVM opts to maven easyb plugin when it runs these easyb tests? At the very minimum it should atleast pick up the MAVEN_OPTS settings from the environment. Has someone bumped into problems like this? (A search on this group's archive does not reveal much)

  • Multiple interfaces inhertience. Casting from one to another

    - by yossi1981
    Consider the following set of classes/Interfaces: class IFish{ public: virtual void eat() = 0; } class IFriendly{ public: virtual void protect() = 0; } class IAggresive{ public: virtual void attack(Point inDest) = 0; } class CDolphin : public IFish, IFriendly{ eat... protect.... } class CShark : public IFish, IAggresive{ eat.... attack... } Now I am having the following class void CDiver { Void shouldRunAway(IFish* fish) { //??? } } My question is , can "shouldRunAway" extract from the fish argument whether it is an IAggresive or IFreindly (if it is any of these at all...) is there some kind of casting that can help out?

  • C# private (hidden) base class

    - by Loadmaster
    It is possible to make a C# base class accessible only within the library assembly it's compiled into, while making other subclasses that inherit from it public? For example: using System.IO; class BaseOutput: Stream // Hidden base class { protected BaseOutput(Stream o) { ... } ...lots of common methods... } public class MyOutput: BaseOutput // Public subclass { public BaseOutput(Stream o): base(o) { ... } public override int Write(int b) { ... } } Here I'd like the BaseOutput class to be inaccessible to clients of my library, but allow the subclass MyOutput to be completely public. I know that C# does not allow base classes to have more restrictive access than subclasses, but is there some other legal way of achieving the same effect?

  • Cocoa Interface Builder object initialization

    - by Stanley
    Base on the documentation and sample code that I have gone through, I got an impression that when a class defined in xcode is read into and configured in Interface Builder, an object based on the class is effectively created and stored in an xib or nib file. So the object is ready to be used when the corresponding application is launched. Alternatively, for classes that have not been handled by Interface Builder, code such as the "new" statements have to be written in xcode explicitly in order for the associated objects to be created and used. It will be very nice to have people who are more knowledgable than me to confirm or to correct my very naive understanding of Interface Builder ...

  • Need help on how to setup my packages and projects in eclipse

    - by jax
    I am new to Java and am making a license generator. This is my current setup. com.example.licensegenerator.client (used by the client application) :LicenseLoader (no Main method) :LicenseDownloader (no Main method) com.example.licensegenerator.server.keys (used by the server) :ProductKeyGenerator(Main method) com.example.licensegenerator.server.license (used on the server also) :LicenseGenerator(Main method) com.example.licensegenerator.lib (Shared classes between client and server) :Contants (no main) Now I have a few questions. Is it OK to have multiple Main() methods in a single project? Will I be able to compile them to different .jar files? (In this case I need two different jars for the server) Is there a better way to setup the packages? And a totally unrelated question, with exceptions, is it better to handle them right then and there or throw them and let the main method catch them all (the program cannot recover if an error occurs)

  • how to made one-to-one bidirectional relationships in grails?

    - by user369759
    I have two domain classes and want to have one-to-one BIDIRECTIONAL relation between them. I write: class Person { Book book; String name Integer age Date lastVisit static constraints = { book unique: true // "one-to-one". Without that = "Many-to-one". } } class Book { String title Date releaseDate String ISBN static belongsTo = [person:Person] // it makes relationship bi-directional regarding the grails-docs } So, i want to have bi-directional, i could NOT find link from Book to Person in generated SQL: CREATE TABLE `book` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `version` bigint(20) NOT NULL, `isbn` varchar(255) NOT NULL, `release_date` datetime NOT NULL, `title` varchar(255) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=latin1 So then it means it is not bidirectional then?

  • Use different Solr Similarity algo for every search

    - by snickernet
    Hi Guys, Is possible in Solr 1.4 to specify which similarity class to use for every search within a single index? Let's say, I got 2 type of search (keyword and brand). For keyword search, I want to use the DefaultSimilarity class. But, for brand search, I want to use my CustomSimilarity class. I've been modifying the schema.xml to specify a single similarity class to use. But, I came to this requirement that I have to use 2 different similarity classes. I'll be glad to here your thoughts on this. Thanks in advance.

  • how to display "complex" widgets in a list in pyqt?

    - by Giorgio Gelardi
    I'm quite new to QT and I have to display a list of "panels" like this: My datamodel handles different classes' instances, so having more than one panel layout would be great - but it's not a requirement. Btw I have to catch mouse clicks on the images to execute related actions. I'm thinking about use some html capable widget (QWebPage?) to render the items in a QListView or QListWidget, but as I said, I don't know QTs so much and need a direction (delegates? stylesheets?). Any help will be appreciated.

Typically, we would have this in code Board uc = (Board)Page.LoadControl(@"~\Board.ascx"); But I want is something like this Board uc = (Board)Page.LoadControl(Board.VirtualPath); OR Board uc = Page.LoadControl(Board); Anyone have an idea how I can accomplish this?

  • Securing input of private / protected methods?

    - by ts
    Hello, normally, all sane developers are trying to secure input of all public methods (casting to proper types, validating, sanitizing etc.) My question is: are you in your code validating also parameters passed to protected / private methods? In my opinion it is not necessary, if you securize properly parameters of public methods and return values from outside (other classes, db, user input etc...). But I am constantly facing frameworks and apps (ie. prestashop to name one) where validation is often repeated in method call, in method body and once again for securize returned value - which, I think, is creating performace overhead and is also a sign of bad design.
