• Svcutil generating bad config with multiple endpoints

  - by vfilby

  I have a WCF service that has exposed a soap and an xml endpoint. When I use svcutil to generate the proxy code on the client side the generated configuration contains two endpoints which causes the client to fail. If I edit the web.config file and remove the second endpoint (with the custom binding) all works as expected. Is there a way I can get svcutil to generate a config that just works so that I don't need to hand edit the file everytime? Client-side error: An endpoint configuration section for contract 'MyNamespace.ITestService' could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name. Svcutil command: svcutil http://api.local/Test.svc /reference:bin\MyNamespace.Interface.dll /config:web.config /mergeConfig /out:"Service References\TestService.cs" /n:*,MyNamespace Generated client config: <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_ITestService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding> <customBinding> <binding name="CustomBinding_ITestService"> <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16" messageVersion="Soap12" writeEncoding="utf-8"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> </textMessageEncoding> </binding> </customBinding> </bindings> <client> <endpoint address="http://api2.local/Test.svc/soap" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ITestService" contract="MyNamespace.ITestService" name="BasicHttpBinding_ITestService" /> <endpoint binding="customBinding" bindingConfiguration="CustomBinding_ITestService" contract="MyNamespace.ITestService" name="CustomBinding_ITestService" /> </client> </system.serviceModel>

• Fluent | Nhibernate multiple inheritance mapping?

  - by Broken Pipe

  I'm trying to map this classes: public interface IBusinessObject { Guid Id { get; set; } } public class Product { public virtual Guid Id { get; set; } public virtual int ProductTypeId { get; set; } } public class ProductWeSell : Product, IBusinessObject { } public class ProductWeDontSell : Product { } Using this Fluent mapping code: public class IBusinessObjectMap : ClassMap<IBusinessObject> { public IBusinessObjectMap() { Id(t => t.Id).GeneratedBy.Guid(); Table("BusinessObject"); } } public class ProductMap : ClassMap<Product> { public ProductMap() { Id(t => t.Id); DiscriminateSubClassesOnColumn("ProductTypeId", "null").Nullable(); } } public class ProductWeSellMap : SubclassMap<ProductWeSell> { public ProductWeSellMap() { DiscriminatorValue(1); KeyColumn("Id"); } } public class ProductWeDontSellMap : SubclassMap<ProductWeDontSell> { public ProductWeDontSellMap() { DiscriminatorValue(2); KeyColumn("Id"); } } But I get {"Duplicate class/entity mapping ProductWeSell"} error. And if we take a look at generated HBM, indeed it's duplicated, but i have no idea how to write this mapping without duplicating it if it's possible at all. Produced hbm: <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class xmlns="urn:nhibernate-mapping-2.2" name="IBusinessObject" table="BusinessObject"> <joined-subclass name="ProductWeSell" table="ProductWeSell"/> </class> </hibernate-mapping> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class xmlns="urn:nhibernate-mapping-2.2" discriminator-value="null" name="Product" table="Product"> <discriminator type="String"> <column name="ProductTypeId" not-null="false" /> </discriminator> <subclass name="ProductWeDontSell" discriminator-value="2" /> <subclass name="ProductWeSell" discriminator-value="1" /> </class> </hibernate-mapping> So far I was unable to figure out how to map this using fluent Nhibernate (i haven't tried mapping this using hmb files). Any help appreciated Fluent or HBM files. The thing I'm trying to solve look identical to this topic: NHibernate inheritance mapping question

• Class Problem (c++ and prolog)

  - by Joshua Green

  I am using the C++ interface to Prolog (the classes and methods of SWI-cpp.h). For working out a simple backtracking that john likes mary and emma and sara: likes(john, mary). likes(john, emma). likes(john, ashley). I can just do: { PlFrame fr; PlTermv av(2); av[0] = PlCompound("john"); PlQuery q("likes", av); while (q.next_solution()) { cout << (char*)av[1] << endl; } } This works in a separate code, so the syntax is correct. But I am also trying to get this simple backtracking to work within a class: class UserTaskProlog { public: UserTaskProlog(ArRobot* r); ~UserTaskProlog(); protected: int cycles; char* argv[1]; ArRobot* robot; void logTask(); }; This class works fine, with my cycles variable incrementing every robot cycle. However, when I run my main code, I get an Unhandled Exception error message: UserTaskProlog::UserTaskProlog(ArRobot* r) : robotTaskFunc(this, &UserTaskProlog::logTask) { cycles = 0; PlEngine e(argv[0]); PlCall("consult('myFile.pl')"); robot->addSensorInterpTask("UserTaskProlog", 50, &robotTaskFunc); } UserTaskProlog::~UserTaskProlog() { robot->remSensorInterpTask(&robotTaskFunc); // Do I need a destructor here for pl? } void UserTaskProlog::logTask() { cycles++; cout << cycles; { PlFrame fr; PlTermv av(2); av[0] = PlCompound("john"); PlQuery q("likes", av); while (q.next_solution()) { cout << (char*)av[1] << endl; } } } I have my opening and closing brackets for PlFrame. I have my frame, my query, etc... The exact same code that backtracks and prints out mary and emma and sara. What am I missing here that I get an error message? Here is what I think the code should do: I expect mary and emma and sara to be printed out once, every time cycles increments. However, it opens SWI-cpp.h file automatically and points to class PlFrame. What is it trying to tell me? I don't see anything wrong with my PlFrame class declaration. Thanks,

• How to configure maximum number of transport channels in WCF using basicHttpBinding?

  - by Hemant

  Consider following code which is essentially a WCF host: [ServiceContract (Namespace = "http://www.mightycalc.com")] interface ICalculator { [OperationContract] int Add (int aNum1, int aNum2); } [ServiceBehavior (InstanceContextMode = InstanceContextMode.PerCall)] class Calculator: ICalculator { public int Add (int aNum1, int aNum2) { Thread.Sleep (2000); //Simulate a lengthy operation return aNum1 + aNum2; } } class Program { static void Main (string[] args) { try { using (var serviceHost = new ServiceHost (typeof (Calculator))) { var httpBinding = new BasicHttpBinding (BasicHttpSecurityMode.None); serviceHost.AddServiceEndpoint (typeof (ICalculator), httpBinding, "http://172.16.9.191:2221/calc"); serviceHost.Open (); Console.WriteLine ("Service is running. ENJOY!!!"); Console.WriteLine ("Type 'stop' and hit enter to stop the service."); Console.ReadLine (); if (serviceHost.State == CommunicationState.Opened) serviceHost.Close (); } } catch (Exception e) { Console.WriteLine (e); Console.ReadLine (); } } } Also the WCF client program is: class Program { static int COUNT = 0; static Timer timer = null; static void Main (string[] args) { var threads = new Thread[10]; for (int i = 0; i < threads.Length; i++) { threads[i] = new Thread (Calculate); threads[i].Start (null); } timer = new Timer (o => Console.WriteLine ("Count: {0}", COUNT), null, 1000, 1000); Console.ReadLine (); timer.Dispose (); } static void Calculate (object state) { var c = new CalculatorClient ("BasicHttpBinding_ICalculator"); c.Open (); while (true) { try { var sum = c.Add (2, 3); Interlocked.Increment (ref COUNT); } catch (Exception ex) { Console.WriteLine ("Error on thread {0}: {1}", Thread.CurrentThread.Name, ex.GetType ()); break; } } c.Close (); } } Basically, I am creating 10 proxy clients and then repeatedly calling Add service method. Now if I run both applications and observe opened TCP connections using netstat, I find that: If both client and server are running on same machine, number of tcp connections are equal to number of proxy objects. It means all requests are being served in parallel. Which is good. If I run server on a separate machine, I observed that maximum 2 TCP connections are opened regardless of the number of proxy objects I create. Only 2 requests run in parallel. It hurts the processing speed badly. If I switch to net.tcp binding, everything works fine (a separate TCP connection for each proxy object even if they are running on different machines). I am very confused and unable to make the basicHttpBinding use more TCP connections. I know it is a long question, but please help!

• Handwritten linked list is segfaulting and I don't understand why

  - by Born2Smile

  Hi I was working on a bit of fun, making an interface to run gnuplot from within c++, and for some reason the my linked list implementation fails. The code below fails on the line plots-append(&plot). Stepping through the code I discovered that for some reason the destructor ~John() is called immediately after the constructor John(), and I cannot seem to figure out why. The code included below is a stripped down version operating only on Plot*. Originally I made the linked list as a template class. And it worked fine as ll<int and ll<char* but for some reason it fails as ll<Plot*. Could youp please help me figure out why it fails? and perhaps help me understand how to make it work? In advance: Thanks a heap! //B2S #include <string.h class Plot{ char title[80]; public: Plot(){ } }; class Link{ Plot* element; Link* next; Link* prev; friend class ll; }; class ll{ Link* head; Link* tail; public: ll(){ head = tail = new Link(); head-prev = tail-prev = head-next = tail-next = head; } ~ll(){ while (head!=tail){ tail = tail-prev; delete tail-next; } delete head; } void append(Plot* element){ tail-element = element; tail-next = new Link(); tail-next-prev = tail; tail-next = tail; } }; class John{ ll* plots; public: John(){ plots= new ll(); } ~John(){ delete plots; } John(Plot* plot){ John(); plots-append(plot); } }; int main(){ Plot p; John k(&p); }

• Delphi: Minimize application to systray

  - by marco92w

  I want to minimize a Delphi application to the systray instead of the task bar. The necessary steps seem to be the following: Create icon which should then be displayed in the systray. When the user clicks the [-] to minimize the application, do the following: Hide the form. Add the icon (step #1) to the systray. Hide/delete the application's entry in the task bar. When the user double-clicks the application's icon in the systray, do the following: Show the form. Un-minimize the application again and bring it to the front. If "WindowState" is "WS_Minimized" set to "WS_Normal". Hide/delete the application's icon in the systray. When the user terminates the application, do the following: Hide/delete the application's icon in the systray. That's it. Right? How could one implement this in Delphi? I've found the following code but I don't know why it works. It doesn't follow my steps described above ... unit uMinimizeToTray; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls, ShellApi; const WM_NOTIFYICON = WM_USER+333; type TMinimizeToTray = class(TForm) procedure FormCreate(Sender: TObject); procedure FormClose(Sender: TObject; var Action: TCloseAction); procedure CMClickIcon(var msg: TMessage); message WM_NOTIFYICON; private { Private-Deklarationen } public { Public-Deklarationen } end; var MinimizeToTray: TMinimizeToTray; implementation {$R *.dfm} procedure TMinimizeToTray.CMClickIcon(var msg: TMessage); begin if msg.lparam = WM_LBUTTONDBLCLK then Show; end; procedure TMinimizeToTray.FormCreate(Sender: TObject); VAR tnid: TNotifyIconData; HMainIcon: HICON; begin HMainIcon := LoadIcon(MainInstance, 'MAINICON'); Shell_NotifyIcon(NIM_DELETE, @tnid); tnid.cbSize := sizeof(TNotifyIconData); tnid.Wnd := handle; tnid.uID := 123; tnid.uFlags := NIF_MESSAGE or NIF_ICON or NIF_TIP; tnid.uCallbackMessage := WM_NOTIFYICON; tnid.hIcon := HMainIcon; tnid.szTip := 'Tooltip'; Shell_NotifyIcon(NIM_ADD, @tnid); end; procedure TMinimizeToTray.FormClose(Sender: TObject; var Action: TCloseAction); begin Action := caNone; Hide; end; end.

• Using in app purchase to unlock features vs. using free & paid app versions for iPhone

  - by yabada

  I have an app that I was going to release as a free (lite) version with some of the total functionality and a paid full version with advanced functionality. Now, with in app purchase for free apps I am thinking of going that route with the ability to unlock features as needed. I'm not talking about a trial version that expires.I want people to be able to try out the app and get an idea of the interface and functionality before deciding to purchase the full functionality of each major section of the app, basically. Here's an analogy of what my app would be like. Let's say you have a cooking app that teaches you to cook in different styles. There could be major section for French, Italian, and Chinese. Each section could have some rudiments unlocked in the free app so users can see the UI and basics of the functionality. Then, the user could decide to purchase each major section (or not) individually with in app purchase or buy the full versioned app (with the free/paid model). One concern I have with offering a free app with in app purchase would be with feedback. I would be very clear in my description in the app store that there is in app purchase for full features but I'm worried that less serious users could/would leave negative feedback. I suppose that's always a risk but curious about any experience with this. It also seems that it could be a whole lot more complicated keeping track of what portions of the app are locked and unlocked with in app purchase. I know I'd have to have all the code for the full functionality and "lock" the portions that haven't been purchased. How do people usually lock portions of their code? I'm not talking about the process of purchasing (I've read the In App Purchase Programming Guide) but after the purchase has been made. Would I just keep track of what the user has purchased and put conditionals on the sections that are initially locked? Or is there another way to do this as well? My instinct is for the in app purchase (particularly since users could purchase the major sections that they want individually).

• ASP.NET MVC2: Can you get ModelMetadata.ContainerType from within a collection?

  - by CodeSponge

  I'm trying to call DisplayFor and DisplayForModel to iterate an IEnumerable< with various element types from within a view. I have Templates defined for each element/Model type. What I would like to do is check the ViewData.ModelMetadata.ContainerType from within the Template so that Template can determine if it was called as part of a collection. A simple example: Index1.aspx: To render a collection of Foos. <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<Foo>>" %> <asp:Content ContentPlaceHolderID="MainPlaceHolder" runat="server"> <ul><%:Html.DisplayForModel()%></ul> </asp:Content> Index2.aspx: To render a Foo. <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Foo>" %> <asp:Content ContentPlaceHolderID="MainPlaceHolder" runat="server"> <%:Html.DisplayForModel()%> </asp:Content> Shared\DisplayTemplates\Foo.ascx: A context aware Template for Foo. <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Foo>" %> <% var tag = typeof(IEnumerable).IsAssignableFrom(ViewData.ModelMetaData.ContainerType) ? "li" : "div"; %> <<%:tag%>><%:Model.Name%></<%:tag%>> The problem with this example is that ViewData.ModelMetaData.ContainerType is null in the Template when resolved though Index1.aspx. From what I've read on Brad Wilson post and others it has to do with the use of IEnumerable and its being an interface. Is there a way to insure that the ContainerType is set? Perhaps by creating a ModelMetadataProviders? I looked into that breifly but it appears the ContainerType value is determined before and then passed to the Provider. Any suggestions would be appreciated.

• Windows forms application blocks after station lock

  - by Silviu

  We're having a serious issue at work. We've discovered that after the station where the client was running is locked/unlocked the client is blocked. No repaint. So the UI thread is blocked with something. Looking at the callstack of the UI thread (thread 0) using windbg we see that a UserPreferenceChanged event gets raised. It is marshalled through a WindowsFormsSynchronizationContext using it's controlToSend field to the UI. It gets blocked by a call to the marshalling control. The method called is MarshaledInvoke it builds a ThreadMethodEntry entry = new ThreadMethodEntry(caller, method, args, synchronous, executionContext); This entry is supposed to do the magic. The call is a synchronous call and because of that (still in the MarshaledInvoke of the Control class) the wait call is reached: if (!entry.IsCompleted) { this.WaitForWaitHandle(entry.AsyncWaitHandle); } The last thing that i can see on the stack is the WaitOne called on the previously mentioned AsyncWaitHandle. This is very annoying because having just the callstack of the runtime and not one of our methods being invoked we cannot really point to a bug in our code. I might be wrong, but I'm guessing that the marshaling control is not "marshaling" to the ui thread. But another one...i don't really know which one because the other threads are being used by us and are blocked...maybe this is the issue. But none of the other threads are running a message loop. This is very annoying. We had some issues in the past with marshaling controls to the right ui thread. That is because the first form that is constructed is a splash form. Which is not the main form. We used to use the main form to marshal call to the ui thread. But from time to time some calls would go to a non ui thread and some grids would broke with a big red X on them. I fixed this by creating a specific class: public class WindowsFormsSynchronizer { private static readonly WindowsFormsSynchronizationContext = new WindowsFormsSynchronizationContext(); //Methods are following that would build the same interface of the synchronization context. } This class gets build as one of the first objects in the first form being constructed. We've noticed some other strange thing. Looking at the heap there are 7 WindowsFormsSynchronizationContext objects. 6 of these have the same instance of controlToSend, and the other one has some different instance of controlToSend. This last one is the one that should marshal the calls to the UI. I don't have any other idea...maybe some of you guys had this same issue?

• How do I repair the corrupted files found by sfc /scannow? "Windows Resource Protection found corrupt files but was unable to fix some of them."

  After running chkdsk C: /F /R and finding out that my hard disk has 24 KB in bad sectors (log is posted below), I decided to run Windows 7's System File Checker utility (sfc /scannow).

• Is the design notion of layers contrived?

  - by Bruce

  Hi all I'm reading through Eric Evans' awesome work, Domain-Driven Design. However, I can't help feeling that the 'layers' model is contrived. To expand on that statement, it seems as if it tries to shoe-horn various concepts into a specific, neat model, that of layers talking to each other. It seems to me that the layers model is too simplified to actually capture the way that (good) software works. To expand further: Evans says: "Partition a complex program into layers. Develop a design within each layer that is cohesive and that depends only on the layers below. Follow standard architectural patterns to provide loose coupling to the layers above." Maybe I'm misunderstanding what 'depends' means, but as far as I can see, it can either mean a) Class X (in the UI for example) has a reference to a concrete class Y (in the main application) or b) Class X has a reference to a class Y-ish object providing class Y-ish services (ie a reference held as an interface). If it means (a), then this is clearly a bad thing, since it defeats re-using the UI as a front-end to some other application that provides Y-ish functionality. But if it means (b), then how is the UI any more dependent on the application, than the application is dependent on the UI? Both are decoupled from each other as much as they can be while still talking to each other. Evans' layer model of dependencies going one way seems too neat. First, isn't it more accurate to say that each area of the design provides a module that is pretty much an island to itself, and that ideally all communication is through interfaces, in a contract-driven/responsibility-driven paradigm? (ie, the 'dependency only on lower layers' is contrived). Likewise with the domain layer talking to the database - the domain layer is as decoupled (through DAO etc) from the database as the database is from the domain layer. Neither is dependent on the other, both can be swapped out. Second, the idea of a conceptual straight line (as in from one layer to the next) is artificial - isn't there more a network of intercommunicating but separate modules, including external services, utility services and so on, branching off at different angles? Thanks all - hoping that your responses can clarify my understanding on this..

• How to optimize Core Data query for full text search

  - by dk

  Can I optimize a Core Data query when searching for matching words in a text? (This question also pertains to the wisdom of custom SQL versus Core Data on an iPhone.) I'm working on a new (iPhone) app that is a handheld reference tool for a scientific database. The main interface is a standard searchable table view and I want as-you-type response as the user types new words. Words matches must be prefixes of words in the text. The text is composed of 100,000s of words. In my prototype I coded SQL directly. I created a separate "words" table containing every word in the text fields of the main entity. I indexed words and performed searches along the lines of SELECT id, * FROM textTable JOIN (SELECT DISTINCT textTableId FROM words WHERE word BETWEEN 'foo' AND 'fooz' ) ON id=textTableId LIMIT 50 This runs very fast. Using an IN would probably work just as well, i.e. SELECT * FROM textTable WHERE id IN (SELECT textTableId FROM words WHERE word BETWEEN 'foo' AND 'fooz' ) LIMIT 50 The LIMIT is crucial and allows me to display results quickly. I notify the user that there are too many to display if the limit is reached. This is kludgy. I've spent the last several days pondering the advantages of moving to Core Data, but I worry about the lack of control in the schema, indexing, and querying for an important query. Theoretically an NSPredicate of textField MATCHES '.*\bfoo.*' would just work, but I'm sure it will be slow. This sort of text search seems so common that I wonder what is the usual attack? Would you create a words entity as I did above and use a predicate of "word BEGINSWITH 'foo'"? Will that work as fast as my prototype? Will Core Data automatically create the right indexes? I can't find any explicit means of advising the persistent store about indexes. I see some nice advantages of Core Data in my iPhone app. The faulting and other memory considerations allow for efficient database retrievals for tableview queries without setting arbitrary limits. The object graph management allows me to easily traverse entities without writing lots of SQL. Migration features will be nice in the future. On the other hand, in a limited resource environment (iPhone) I worry that an automatically generated database will be bloated with metadata, unnecessary inverse relationships, inefficient attribute datatypes, etc. Should I dive in or proceed with caution?

• Defining a Class in Objective C, XCode

  - by Brett

  Hello; I am new to Objective C, and am trying to write a class that defines a complex number. The code seems fine but when I print to the console, my values for instance variables are 0. Here is the code: // // ComplexNumber.h // Mandelbrot Set // // Created by Brett on 10-06-02. // Copyright 2010 __MyCompanyName__.

Help?

• Performing dynamic sorts on EF4 data

  - by Jaxidian

  I'm attempting to perform dynamic sorting of data that I'm putting into grids into our MVC UI. Since MVC is abstracted from everything else via WCF, I've created a couple utility classes and extensions to help with this. The two most important things (slightly simplified) are as follows: public static IQueryable<T> ApplySortOptions<T, TModel, TProperty>(this IQueryable<T> collection, IEnumerable<ISortOption<TModel, TProperty>> sortOptions) where TModel : class { var sortedSortOptions = (from o in sortOptions orderby o.Priority ascending select o).ToList(); var results = collection; foreach (var option in sortedSortOptions) { var currentOption = option; var propertyName = currentOption.Property.MemberWithoutInstance(); var isAscending = currentOption.IsAscending; if (isAscending) { results = from r in results orderby propertyName ascending select r; } else { results = from r in results orderby propertyName descending select r; } } return results; } public interface ISortOption<TModel, TProperty> where TModel : class { Expression<Func<TModel, TProperty>> Property { get; set; } bool IsAscending { get; set; } int Priority { get; set; } } I've not given you the implementation for MemberWithoutInstance() but just trust me in that it returns the name of the property as a string. :-) Following is an example of how I would consume this (using a non-interesting, basic implementation of ISortOption<TModel, TProperty>): var query = from b in CurrentContext.Businesses select b; var sortOptions = new List<ISortOption<Business, object>> { new SortOption<Business, object> { Property = (x => x.Name), IsAscending = true, Priority = 0 } }; var results = query.ApplySortOptions(sortOptions); As I discovered with this question, the problem is specific to my orderby propertyName ascending and orderby propertyName descending lines (everything else works great as far as I can tell). How can I do this in a dynamic/generic way that works properly?

• How do you handle EF Data Contexts combined with asp.net custom membership/role providers

  - by KallDrexx

  I can't seem to get my head around how to implement a custom membership provider with Entity Framework data contexts into my asp.net MVC application. I understand how to create a custom membership/role provider by itself (using this as a reference). Here's my current setup: As of now I have a repository factory interface that allows different repository factories to be created (right now I only have a factory for EF repositories and and in memory repositories). The repository factory looks like this: public class EFRepositoryFactory : IRepositoryFactory { private EntitiesContainer _entitiesContext; /// <summary> /// Constructor that generates the necessary object contexts /// </summary> public EFRepositoryFactory() { _entitiesContext = new EntitiesContainer(); } /// <summary> /// Generates a new entity framework repository for the specified entity type /// </summary> /// <typeparam name="T">Type of entity to generate a repository for </typeparam> /// <returns>Returns an EFRepository</returns> public IRepository<T> GenerateRepository<T>() where T : class { return new EFRepository<T>(_entitiesContext); } } Controllers are passed an EF repository factory via castle Windsor. The controller then creates all the service/business layer objects it requires and passes in the repository factory into it. This means that all service objects are using the same EF data contexts and I do not have to worry about objects being used in more than one data context (which of course is not allowed and causes an exception). As of right now I am trying to decide how to generate my user and authorization service layers, and have run against a design roadblock. The User/Authization service will be a central class that handles the logic for logging in, changing user details, managing roles and determining what users have access to what. The problem is, using the current methodology the asp.net mvc controllers will initialize it's own EF repository factory via Windsor and the asp.net membership/role provider will have to initialize it's own EF repository factory. This means that each part of the site will then have it's own data context. This seems to mean that if asp.net authenticates a user, that user's object will be in the membership provider's data context and thus if I try to retrieve that user object in the service layer (say to change the user's name) I will get a duplication exception. I thought of making the repository factory class a singleton, but I don't see a way for that to work with castle Windsor. How do other people handle asp.net custom providers in a MVC (or any n-tier) architecture without having object duplication issues?

• Problems integrating nServiceBus with StructureMap

  - by SimonB

  I'm trying to use StructureMap with nServiceBus. The Project: Uses a GenericHost Endpoint to send command messages Configures nServiceBus using the StructMapBuilder. Uses a simple StructureMap registry config Uses a start up class TestServer supporting IWantToRunAtStartup The TestServer class has ctor dependency on a TestManager class The TestManager class has ctor dependency on IBus ObjectFactory.WhatDoIHave() shows StructureMap knows how to construct the classes. When run I get buildup errors. nServiceBus seems to be overwriting the config? Note that when I add a IBus ctor depenendency to my event handlers without any other config all appears fine. Error: Exception when starting endpoint, error has been logged. Reason: Error creating object with name 'nSeviceBusStructureMapTest.TestServer' : Unsatisfied dependency expressed through constructor argument with index 0 of type [nSeviceBusStructureMapTest.ITestManager] : No unique object of type [nSeviceBusStructureMapTest.ITestManager] is defined : Unsatisfied dependency of type [nSeviceBusStructureMapTest.ITestManager]: expected at least 1 matching object to wire the [miningServiceManage] parameter on the constructor of object [nSeviceBusStructureMapTest.TestServer] Source: using System; using System.Diagnostics; using NServiceBus; using StructureMap; using StructureMap.Configuration.DSL; namespace nSeviceBusStructureMapTest { public class TestSmRegistry : Registry { public TestSmRegistry() { For<ITestManager>().Use<TestManager>(); For<TestServer>().Use<TestServer>(); } } public class TestEndPoint : AsA_Server, IConfigureThisEndpoint, IWantCustomLogging { public void Init() { Configure.With().StructureMapBuilder(ObjectFactory.Container); ObjectFactory.Configure(c => c.AddRegistry<TestSmRegistry>()); Debug.WriteLine(ObjectFactory.WhatDoIHave()); } } public class TestServer : IWantToRunAtStartup { public TestServer(ITestManager miningServiceManage) { _miningServiceManage = miningServiceManage; } private readonly ITestManager _miningServiceManage; public void Run() { _miningServiceManage.Run(); } public void Stop() { } } public interface ITestManager { void Run(); } public class TestManager : ITestManager { public TestManager(IBus bus) { _bus = bus; } private readonly IBus _bus; public void Run() { if (_bus == null) Debug.WriteLine("Error no bus"); // Send messages on bus; } } } <MsmqTransportConfig InputQueue="test" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" /> <UnicastBusConfig> <MessageEndpointMappings> </MessageEndpointMappings> </UnicastBusConfig> Any ideas?

• Problem retrieving HTML5 video duration

  - by drebabels

  UPDATE: Ok so although I haven't solved this problem exactly, but I did figure out a work around that handles my biggest concern... the user experience. First the video doesn't begin loading until after the viewer hits the play button, so I am assuming that the duration information wasn't available to be pulled (I don't know how to fix this particular issue... although I assume that it would involve just loading the video metadata separately from the video, but I don't even know if that is possible). So to get around the fact that there is no duration data, I decided to hide the duration info (and actually the entire control) completely until you hit play. I know... its cheating. But for now it makes me happy :) That said... if anyone knows how to load the video metadata separately from the video file... please share. I think that should completely solve this problem. I am working on building a HTML5 video player with a custom interface, but I am having some problems getting the video duration information to display. My HTML is real simple (see below) <video id="video" poster="image.jpg" controls> <source src="video_path.mp4" type="video/mp4" /> <source src="video_path.ogv" type="video/ogg" /> </video> <ul class="controls"> <li class="time"><p><span id="timer">0</span> of <span id="duration">0</span></p></li> </ul> And the javascript I am using to get and insert the duration is var duration = $('#duration').get(0); var vid_duration = Math.round(video.duration); duration.firstChild.nodeValue = vid_duration; The problem is nothing happens. I know the video file has the duration data because if I just use the default controls, it displays fine. But the real strange thing is if I put alert(duration) in my code like so alert(duration); var vid_duration = Math.round(video.duration); duration.firstChild.nodeValue = vid_duration; then is works fine (minus the annoying alert that pops up). Any ideas what is happening here or how I can fix it?

• Custom NSView in NSMenuItem not receiving mouse events

  - by Dennis

  I have an NSMenu popping out of an NSStatusItem using popUpStatusItemMenu. These NSMenuItems show a bunch of different links, and each one is connected with setAction: to the openLink: method of a target. This arrangement has been working fine for a long time. The user chooses a link from the menu and the openLink: method then deals with it. Unfortunately, I recently decided to experiment with using NSMenuItem's setView: method to provide a nicer/slicker interface. Basically, I just stopped setting the title, created the NSMenuItem, and then used setView: to display a custom view. This works perfectly, the menu items look great and my custom view is displayed. However, when the user chooses a menu item and releases the mouse, the action no longer works (i.e., openLink: isn't called). If I just simply comment out the setView: call, then the actions work again (of course, the menu items are blank, but the action is executed properly). My first question, then, is why setting a view breaks the NSMenuItem's action. No problem, I thought, I'll fix it by detecting the mouseUp event in my custom view and calling my action method from there. I added this method to my custom view: - (void)mouseUp:(NSEvent *)theEvent { NSLog(@"in mouseUp"); } No dice! This method is never called. I can set tracking rects and receive mouseEntered: events, though. I put a few tests in my mouseEntered routine, as follows: if ([[self window] ignoresMouseEvents]) { NSLog(@"ignoring mouse events"); } else { NSLog(@"not ignoring mouse events"); } if ([[self window] canBecomeKeyWindow]) { dNSLog((@"canBecomeKeyWindow")); } else { NSLog(@"not canBecomeKeyWindow"); } if ([[self window] isKeyWindow]) { dNSLog((@"isKeyWindow")); } else { NSLog(@"not isKeyWindow"); } And got the following responses: not ignoring mouse events canBecomeKeyWindow not isKeyWindow Is this the problem? "not isKeyWindow"? Presumably this isn't good because Apple's docs say "If the user clicks a view that isn’t in the key window, by default the window is brought forward and made key, but the mouse event is not dispatched." But there must be a way do detect these events. HOW? Adding: [[self window] makeKeyWindow]; has no effect, despite the fact that canBecomeKeyWindow is YES.

• Non-linear regression models in PostgreSQL using R

  - by Dave Jarvis

  Background I have climate data (temperature, precipitation, snow depth) for all of Canada between 1900 and 2009. I have written a basic website and the simplest page allows users to choose category and city. They then get back a very simple report (without the parameters and calculations section): The primary purpose of the web application is to provide a simple user interface so that the general public can explore the data in meaningful ways. (A list of numbers is not meaningful to the general public, nor is a website that provides too many inputs.) The secondary purpose of the application is to provide climatologists and other scientists with deeper ways to view the data. (Using too many inputs, of course.) Tool Set The database is PostgreSQL with R (mostly) installed. The reports are written using iReport and generated using JasperReports. Poor Model Choice Currently, a linear regression model is applied against annual averages of daily data. The linear regression model is calculated within a PostgreSQL function as follows: SELECT regr_slope( amount, year_taken ), regr_intercept( amount, year_taken ), corr( amount, year_taken ) FROM temp_regression INTO STRICT slope, intercept, correlation; The results are returned to JasperReports using: SELECT year_taken, amount, year_taken * slope + intercept, slope, intercept, correlation, total_measurements INTO result; JasperReports calls into PostgreSQL using the following parameterized analysis function: SELECT year_taken, amount, measurements, regression_line, slope, intercept, correlation, total_measurements, execute_time FROM climate.analysis( $P{CityId}, $P{Elevation1}, $P{Elevation2}, $P{Radius}, $P{CategoryId}, $P{Year1}, $P{Year2} ) ORDER BY year_taken This is not an optimal solution because it gives the false impression that the climate is changing at a slow, but steady rate. Questions Using functions that take two parameters (e.g., year [X] and amount [Y]), such as PostgreSQL's regr_slope: What is a better regression model to apply? What CPAN-R packages provide such models? (Installable, ideally, using apt-get.) How can the R functions be called within a PostgreSQL function? If no such functions exist: What parameters should I try to obtain for functions that will produce the desired fit? How would you recommend showing the best fit curve? Keep in mind that this is a web app for use by the general public. If the only way to analyse the data is from an R shell, then the purpose has been defeated. (I know this is not the case for most R functions I have looked at so far.) Thank you!

• Bind listbox in WPF with grouping

  - by Michael Stoll

  Hi, I've got a collection of ViewModels and want to bind a ListBox to them. Doing some investigation I found this. So my ViewModel look like this (Pseudo Code) interface IItemViewModel { string DisplayName { get; } } class AViewModel : IItemViewModel { string DisplayName { return "foo"; } } class BViewModel : IItemViewModel { string DisplayName { return "foo"; } } class ParentViewModel { IEnumerable<IItemViewModel> Items { get { return new IItemViewModel[] { new AItemViewModel(), new BItemViewModel() } } } } class GroupViewModel { static readonly GroupViewModel GroupA = new GroupViewModel(0); static readonly GroupViewModel GroupB = new GroupViewModel(1); int GroupIndex; GroupViewModel(int groupIndex) { this.GroupIndex = groupIndex; } string DisplayName { get { return "This is group " + GroupIndex.ToString(); } } } class ItemGroupTypeConverter : IValueConverter { object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (value is AItemViewModel) return GroupViewModel.GroupA; else return GroupViewModel.GroupB; } } And this XAML <UserControl.Resources> <vm:ItemsGroupTypeConverter x:Key="ItemsGroupTypeConverter "/> <CollectionViewSource x:Key="GroupedItems" Source="{Binding Items}"> <CollectionViewSource.GroupDescriptions> <PropertyGroupDescription Converter="{StaticResource ItemsGroupTypeConverter }"/> </CollectionViewSource.GroupDescriptions> </CollectionViewSource> </UserControl.Resources> <ListBox ItemsSource="{Binding Source={StaticResource GroupedItems}}"> <ListBox.GroupStyle> <GroupStyle> <GroupStyle.HeaderTemplate> <DataTemplate> <TextBlock Text="{Binding DisplayName}" FontWeight="bold" /> </DataTemplate> </GroupStyle.HeaderTemplate> </GroupStyle> </ListBox.GroupStyle> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding DisplayName}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> This works somehow, exept of the fact that the binding of the HeaderTemplate does not work. Anyhow I'd prefer omitting the TypeConverter and the CollectionViewSource. Isn't there a way to use a property of the ViewModel for Grouping? I know that in this sample scenario it would be easy to replace the GroupViewModel with a string an have it working, but that's not an option. So how can I bind the HeaderTemplate to the GroupViewModel?

• Convert UIViews made programmatically to UIScrollViews

  - by Scott

  So I have a bunch of UIViews that I made programmatically and placed a bunch of content on (UIButtons, UILabels, UINavigationBars, etc.), and most of these views are going to need to actually be UIScrollViews instead. Now keep in mind I made all these through code not the Interface Builder. What I first tried was to just change each declaration of a UIView to a UIScrollView instead, and that compiled and ran fine, however, they were not scrollable. It's REALLY weird. Here is the code that I change into UIScrollViews, although it doesn't scroll: - (void)loadView { //allocate the view self.view = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; //self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; //set the view's background color self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"MainBG.jpg"]]; [self.view addSubview:[SiteOneController myNavBar1:@"Sites"]]; NSMutableArray *sites = [[NSMutableArray alloc] init]; NSString *one = @"Constution Center"; NSString *two = @"Franklin Court"; NSString *three = @"Presidents House"; [sites addObject: one]; [one release]; [sites addObject: two]; [two release]; [sites addObject: three]; [three release]; NSString *element; int j = 0; for (element in sites) { UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; UIFont *myBoldFont = [UIFont boldSystemFontOfSize:20.0]; UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(20, b + (j*45), c, d)]; [label setBackgroundColor:[UIColor clearColor]]; label.text = element; label.font = myBoldFont; UIImage *img = [UIImage imageNamed:@"ButtonBase.png"]; [button setImage:img forState:UIControlStateNormal]; //setframe (where on screen) //separation is 15px past the width (45-30) button.frame = CGRectMake(a, b + (j*45), c, d); // [button setTitle:element forState:UIControlStateNormal]; button.backgroundColor = [SiteOneController myColor1]; [button addTarget:self action:@selector(showCCView:) forControlEvents:UIControlEventTouchUpInside]; [button setTag:j]; [self.view addSubview: button]; [self.view addSubview:label]; j++; } } What am I doing wrong?
