  • WCF Binding Created In Code

    - by Daniel
    Hello I've a must to create wcf service with parameter. I'm following this http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/8f18aed8-8e34-48ea-b8be-6c29ac3b4f41 First this is that I don't know how can I set this custom behavior "MyServiceBehavior" in my Web.config in ASP.NET MVC app that will host it.

  • JSR-299 CDI / Weld vs. Google Guice

    - by deamon
    Weld, the JSR-299 Contexts and Dependency Injection reference implementation, considers itself as a kind of successor of Spring and Guice. CDI was influenced by a number of existing Java frameworks, including Seam, Guice and Spring. However, CDI has its own, very distinct, character: more typesafe than Seam, more stateful and less XML-centric than Spring, more web and enterprise-application capable than Guice. But it couldn't have been any of these without inspiration from the frameworks mentioned and lots of collaboration and hard work by the JSR-299 Expert Group (EG). http://docs.jboss.org/weld/reference/latest/en-US/html/1.html What makes Weld more capable for enterprise application compared to Guice? Are there any advantages or disadvantages compared to Guice? What do you think about Guice AOP compared to Weld interceptors? What about performance?

  • Detach an entity from a JPA persistence context (JPA 2.0 / Hibernate / EJB 3 / J2EE 6)

    - by Julien
    Hi, I wrote a stateless EJB method allowing to get an entity in "read-only" mode. The way to do this is to get the entity with the EntityManager then detach it (using the JPA 2.0 EntityManager). My code is the following: @PersistenceContext private EntityManager entityManager; public T getEntity(int entityId, Class<T> specificClass, boolean readOnly) throws Exception{ try{ T entity = (T)entityManager.find(specificClass, entityId); if (readOnly){ entityManager.detach(entity); } return entity; }catch (Exception e){ logger.error("", e); throw e; } } Getting the entity works fine, but the call to the detach method returns the following error: GRAVE: javax.ejb.EJBException at ... Caused by: java.lang.AbstractMethodError: org.hibernate.ejb.EntityManagerImpl.detach(Ljava/lang/Object;)V at com.sun.enterprise.container.common.impl.EntityManagerWrapper.detach(EntityManagerWrapper.java:973) at com.mycomp.dal.MyEJB.getEntity(MyEJB.java:37) I can't get more information and don't understand what the problem is... Could somebody help ?

  • Subsonic : Can’t decide which property to consider the Key? foreign key issue.

    - by AJ
    Hi I am trying to select count of rows from a table which has foreign keys of two tables. The C# code threw the error mentioned below. So, I added a primary key column to the table (schema as follows) and regenerated the code. But still the same error is coming. Error : Can't decide which property to consider the Key - you can create one called 'ID' or mark one with SubSonicPrimaryKey attribute sqLite Table schema CREATE TABLE "AlbumDocuments" ("Id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL , "AlbumId" INTEGER NOT NULL CONSTRAINT fk_AlbumId REFERENCES Albums(Id) , "DocumentId" INTEGER NOT NULL CONSTRAINT fk_DocumentId REFERENCES Documents(Id)) C# code int selectAlbumDocumentsCount = new SubSonic.Query.Select() .From<DocSafeDB.DataLayer.AlbumDocumentsTable>() .Where(DocSafeDB.DataLayer.AlbumDocumentsTable.AlbumIdColumn).In(request.AlbumId) .Execute(); Not sure what I should be doing next as I can't do where against primary key because I don;t have that info. So my questions are: How do I select count of rows against foreign key column? Is primary key required in this scenario? I have several things but not sure why its not working. To me it looks like a very normal use case. Please advise. Thanks AJ

  • Convert WPF BitmapSource to Icon for window

    - by simmotech
    I have a 16x16 .png file which I have loaded as an ImageSource (BitmapSource) and it is working fine when I use it on an Image in a tabcontrol header. I now want to use that same image in a floating window (inherited from the WPF Window class) when the user drags the document tab. (This is AvalonDock which I have tweaked to allow images in the tab header) After many searches on the web, I understand that Window.Icon requires a BitmapFrame but all the sample code seems to assume that a .ico file is available which it isn't in my case. I have tried the following code (plus variants including cloning, freezing etc): var image = (Image) content.Icon; var bitmapSource = (BitmapSource) image.Source; Icon = BitmapFrame.Create(bitmapSource); but when the Show() method is called, an exception is thrown: "Exception of type 'System.ExecutionEngineException' was thrown." How can a I create a compatible bitmap on the fly to allow the Window to display the icon?

  • Svcutil.exe for .Net 4.0?

    - by D.H.
    I was trying to use svcutil.exe to generate proxy classes for a service but when I use the /reference option to reference an assembly that is built for .Net 4.0 I get an error. Could not load file or assembly [...] or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. So it seems that I am using an old version of svcutil.exe. I am using the one in "C:\Program Files\Microsoft SDKs\Windows\v7.0A which was the latest one I could find. Is there a later version somewhere that I am supposed to use?

  • using java.util.Scanner to read a file byte by byte

    - by openidsucks
    I'm trying to read a one line file character by character using java.util.Scanner.

Edit: I realized I wrote hasNext() instead of hasNextByte(). However if I do that it doesn't print out anything.

  • log4net dependency problem

    - by Alex DeLarge
    I have an issue with log4net which has been bugging me for a while and I've resolved to sort it. I have a class library which references log4net. If I reference this class library in another project I must then reference log4net in this project otherwise I get a build error Unknown build error, 'Cannot resolve dependency to assembly 'log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.' I'm aware that the error message is probably telling me the solution, unfortunately I don't speak gibberish... Cheers guys Alex..

  • Rewind request body stream

    - by Despertar
    I am re-implementing a request logger as Owin Middleware which logs the request url and body of all incoming requests. I am able to read the body, but if I do the body parameter in my controller is null. I'm guessing it's null because the stream position is at the end so there is nothing left to read when it tries to deserialize the body. I had a similar issue in a previous version of Web API but was able to set the Stream position back to 0. This particular stream throws a This stream does not support seek operations exception. In the most recent version of Web API 2.0 I could call Request.HttpContent.ReadAsStringAsync()inside my request logger, and the body would still arrive to the controller in tact. How can I rewind the stream after reading it? or How can I read the request body without consuming it? public class RequestLoggerMiddleware : OwinMiddleware { public RequestLoggerMiddleware(OwinMiddleware next) : base(next) { } public override Task Invoke(IOwinContext context) { return Task.Run(() => { string body = new StreamReader(context.Request.Body).ReadToEnd(); // log body context.Request.Body.Position = 0; // cannot set stream position back to 0 Console.WriteLine(context.Request.Body.CanSeek); // prints false this.Next.Invoke(context); }); } } public class SampleController : ApiController { public void Post(ModelClass body) { // body is now null if the middleware reads it } }

  • C# Implementing a custom stream writer-esque class

    - by Luke
    How would I go about writing my own stream manipulator class? Basically what I'm trying to wrap my head around is storing the reference to the underlying stream in the writer. For example, when writing to a memory stream using a StreamWriter, when a Write() is made, the underlying memory stream is written to. Can I store the reference to an underlying stream without using pointers or unsafe code? Even if it was just a string I wanted to "write" to. Really this has little to do with stream writers, and I'm just wondering how I could store references in a class. The StreamWriter was the best example I could come up with for this.

  • Android: How to obtain Mac Address of WiFi Network Interface?

    - by Gubatron
    It seems the java.net.NetworkInterface implementation of android does not have a byte[] getHardwareAddress() method http://developer.android.com/reference/java/net/NetworkInterface.html I've found several forums of people trying to do this with no definitive answer, I need to get a somewhat cross-device UUID, so I can't rely on phone numbers or in ANDROID_ID (which can be overwritten and which I think depends on the user having a google account) http://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID In linux you can use ifconfig or read from /proc/net/arp and you can easily get the Hardware address. Is there a file in android that I can read? There has to be a way to get this address since it's shown in the "Settings About Phone Status" of the phone.

  • Excel get_Range missing when interop assembly is embedded in .NET 4.0

    - by mikemay
    I build an assembly referencing a COM interop DLL. If I embed the COM interop types by setting Embed Interop Types to True in the Reference's properties (VS2010), at run-time an error occurs "object does not contain a definition for get_Range". If COM interop types are not embedded then no error occurs. Does anyone know why a particular method, Worksheet.get_Range should be ommitted or how to work around this or have any other relevant insights? I should be grateful for any help. The interop dll contains a reference to Worksheet.get_Range(object, [object]). Using reflector on my calling assembly there is no mention of get_Range under Worksheet. The interop assembly I am embedding is generated from Excel9.olb. I am not using PIAs as the application targets multiple Excel versions.

  • Using Data Annotations on POCO's with MVC for Remote Validation

    - by Click Ahead
    Hi All, I am developing an ASP.NET MVC app and I've been looking into using Data Annotations on my POCO's which are defined in my Service Layer. As long as I have a reference to System.ComponentModel & System.ComponentModel.DataAnnotations this is no problem and what I like about this is that it allows me to reuse my Service Layer in a Win Forms app. I'm now looking to do some Remote Validation using Data Annotations and have taken a look at this article: http://msdn.microsoft.com/en-us/library/ff398048(VS.100).aspx However, to use the Data Annotations in this context I need to reference System.Web.MVC, System.Web and System.Web.Routing. This introduces a dependency on the Web DLL's, which limits me somewhat. Can anyone recommend a good clean way to implement Remote Data Validation using Data Annotations that isn't coupled with ASP.NET MVC or maybe suggest a better alternative. Thanks for the help !

  • Update EntitySet<> LINQ to SQL references

    I know that when attaching an entity into a DataContext you have to also attach the related referenced objects manually too. While I'm attaching the EntityRef<'s everything works as expected and my entities are updated to the database. But i have noticed that a problem occurs while trying to attach the EntitySet<'s. I dont use rowversion columns so I'm attaching for every entity on the EntitySet< using original values. Tried just attaching AttachAll() the EntitySet< with no luck and no exception too. There is no exception but the update is not really happening. What am i missing?

    Here is simple example I've created after reading several topics about jpa bulk inserts, I have 2 persistent objects User, and Site. One user could have many site, so we have one to many relations here. Suppose I want to create user and create/link several sites to user account. Here is how code looks like, considering my willing to use bulk insert for Site objects. User user = new User("John Doe"); user.getSites().add(new Site("google.com", user)); user.getSites().add(new Site("yahoo.com", user)); EntityTransaction tx = entityManager.getTransaction(); tx.begin(); entityManager.persist(user); tx.commit(); But when I run this code (I'm using hibernate as jpa implementation provider) I see following sql output: Hibernate: insert into User (id, name) values (null, ?) Hibernate: call identity() Hibernate: insert into Site (id, url, user_id) values (null, ?, ?) Hibernate: call identity() Hibernate: insert into Site (id, url, user_id) values (null, ?, ?) Hibernate: call identity() So, I means "real" bulk insert not works or I am confused? Here is source code for this example project, this is maven project so you have only download and run mvn install to check output.
