  • C# Linq List Contains Similar Elements

    - by John Peters
    Hi All, I am looking for linq query to see if there exists a similar object I have an object graph as follows Cart myCart = new Cart { List<CartProduct> myCartProduct = new List<CartProduct> { CartProduct cartProduct1 = new CartProduct { List<CartProductAttribute> a = new List<CartProductAttribute> { CartProductAttribute cpa1 = new CartProductAttribute{ title="red" }, CartProductAttribute cpa2 = new CartProductAttribute{ title="small" } } } CartProduct cartProduct2 = new CartProduct { List<CartProductAttribute> d = new List<CartProductAttribute> { CartProductAttribute cpa3 = new CartProductAttribute{ title="john" }, CartProductAttribute cpa4 = new CartProductAttribute{ title="mary" } } } } } I would like to get from the Cart = a CartProduct that has the exact same CartProductAttribute title values as a CartProduct that I need to compare. No more and no less. E.G. I need to find a similar CartProduct that has a CartProductAttribute with title="red" and a cartProductAttribute with title="small" in myCart (eg 'cartProduct1' in the example) CartProduct cartProductToCompare = new CartProduct { List<CartProductAttribute> cartProductToCompareAttributes = new List<CartProductAttribute> { CartProductAttribute cpa5 = new CartProductAttribute{ title="red" }, CartProductAttribute cpa6 = new CartProductAttribute{ title="small" } } } So from object graph myCart cartProduct1 cpa1 (title=red) cpa2 (title=small) cartProduct2 cpa3 (title=john) cpa4 (title=mary) Linq query looking for cartProductToCompare cpa5 (title=red) cpa6 (title=small) Should find cartProduct1 Hope all this makes sense... Thanks

  • Issue with VS 2008 designer and usercontrol.

    - by Ram
    Hello, I have created a custom data grid control. I dragged it on windows form and set its properties like column and all & ran the project. It built successfully and I am able to view the grid control on the form. Now if i try to view that form in designer, I am getting following error.. Object reference not set to an instance of an object. Instances of this error (1) 1.

However I can see the code for the grid in the designer file. Any pointer on this would be a great help.

  • Hibernate: OutOfMemoryError persisting Blob when printing log message

    - by paul
    I have a Hibernate Entity: @Entity class Foo { //... @Lob public byte[] getBytes() { return bytes; } //.... } My VM is configured with a maximum heap size of 512 MB. When I try to persist an object which has a 75 MB large object, I get an OutOfMemoryError. The names of the methods in the stack trace (StringBuilder, ByteArrayBlobType.toLoggableString, pretty.Printer.toString) suggest that hibernate is trying to write a very large log message that contains my object. Am I correct about why hibernate is using so much memory? What is the simplest way to work around this problem? java.lang.OutOfMemoryError: Java heap space at java.lang.AbstractStringBuilder.<init>(AbstractStringBuilder.java:44) at java.lang.StringBuilder.<init>(StringBuilder.java:81) at org.hibernate.type.ByteArrayBlobType.toString(ByteArrayBlobType.java:117) at org.hibernate.type.ByteArrayBlobType.toLoggableString(ByteArrayBlobType.java:127) at org.hibernate.pretty.Printer.toString(Printer.java:53) at org.hibernate.pretty.Printer.toString(Printer.java:90) at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions(AbstractFlushingEventListener.java:97) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:26) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) at org.jboss.seam.persistence.HibernateSessionProxy.flush(HibernateSessionProxy.java:181)

  • django-mptt fields showing up twice, breaking SQL

    - by Dominic Rodger
    I'm using django-mptt to manage a simple CMS, with a model called Page, which looks like this (most presumably irrelevant fields removed): class Page(mptt.Model, BaseModel): title = models.CharField(max_length = 20) slug = AutoSlugField(populate_from = 'title') contents = models.TextField() parent = models.ForeignKey('self', null=True, blank=True, related_name='children', help_text = u'The page this page lives under.') removed fields are called attachments, headline_image, nav_override, and published All works fine using SQLite, but when I use MySQL and try and add a Page using the admin (or using ModelForms and the save() method), I get this: ProgrammingError at /admin/mycms/page/add/ (1110, "Column 'level' specified twice") where the SQL generated is: 'INSERT INTO `kaleo_page` (`title`, `slug`, `contents`, `nav_override`, `parent_id`, `published`, `headline_image_id`, `lft`, `rght`, `tree_id`, `level`, `lft`, `rght`, `tree_id`, `level`) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)' for some reason I'm getting the django-mptt fields (lft, rght, tree_id and level) twice. It works in SQLite presumably because SQLite is more forgiving about what it accepts than MySQL. get_all_field_names() also shows them twice: >>> Page._meta.get_all_field_names() ['attachments', 'children', 'contents', 'headline_image', 'id', 'level', 'lft', 'nav_override', 'parent', 'published', 'rght', 'slug', 'title', 'tree_id'] Which is presumably why the SQL is bad. What could I have done that would result in those fields appearing twice in get_all_field_names()?

  • LGPL and Dual Licensing Ajax Library

    - by Thomas Hansen
    Hi guys, I'm the previous founder of Gaiaware and Gaia Ajax Widgets and when I used to work there we had this rhetoric (which I have confirmed with some very smart FOSS people is correct) that when using a GPL Ajax library you're basically "distributing" the JavaScript which in turn makes the GPL viral clause kick in and forces people to purchase a proprietary license if they're going to build Closed Source stuff... So now I'm the the LGPL world here with Ra-Ajax which is an LGPL licensed library and I've got no intentions of creating a GPL licensed library since I believe strongly in that the LGPL is the "enabler" of the Open Web to prevail. But something interesting have happened which I think might still give me a "business model" here which is the Linking clause of the LGPL which I think goes something like this (pseudo); "If you link to an LGPL licensed thing you get no restrictions on your own derived works"... But so we started creating something we're calling Ajax Starter-Kits which effectively is a "Project Kickstarter" where you can download a finished project/solution which basically enables you to start out with some pre-done boiler plate code for problems such as Ajax DataGrids, Ajax Calendar Applications, Ajax TreeView Applications etc. And the funny thing is that our users would NOT "link" to these, they would effectively BE our users applications... So to wrap up my question. Would this force users of our LGPL licensed Ajax Starter-Kits to LGPL license their own work? Basically if it does we have a business model (and I get very happy) if not I'd just have to hope people would still like to pay us those $29 for our Starter-Kits to support the project... ;) Help rewarded with extreme gratitude...

  • WCF - Increase ReaderQuoatas on REST service

    - by Christo Fur
    I have a WCF REST Service which accepts a JSON string One of the parameters is a large string of numbers This causes the following error - which is visible by tracing and using SVC Trace Viewer There was an error deserializing the object of type CarConfiguration. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Now I've read all sorts of articles advising how to rectify this All of them recommend increasing various config settings on the server and client e.g. http://stackoverflow.com/questions/65452/error-serializing-string-in-webservice-call http://bloggingabout.net/blogs/ramon/archive/2008/08/20/wcf-and-large-messages.aspx http://social.msdn.microsoft.com/Forums/en/wcf/thread/f570823a-8581-45ba-8b0b-ab0c7d7fcae1 So my config file looks like this <webHttpBinding> <binding name="webBinding" maxBufferSize="5242880" maxReceivedMessageSize="5242880" > <readerQuotas maxDepth="5242880" maxStringContentLength="5242880" maxArrayLength="5242880" maxBytesPerRead="5242880" maxNameTableCharCount="5242880"/> </binding> </webHttpBinding> ... ... ... <endpoint address="/" binding="webHttpBinding" bindingConfiguration="webBinding" My problem is that I can change this on the server, but there are no WCF config settings on the client as its a REST service and I'm just making a http request using the WebClient object any ideas?

  • Question regarding the iPhone In App Purchase capabilities

    - by Wesley
    Hi everyone. I am working on releasing an app that will greatly benefit from using the in app purchase model. The app is a sort of book viewer, and the content I would like to make available for purchase will be more books in various languages. Each book is stored in sqlite format, in separate .db files. Now, the way that my developer has set it all up is that he added a line onto the bottom of the info.plist file called databases. Inside that database section, I can type in 'es' as the key, and for the value the name of the spanish database, and it populates in a uitableview in spanish, using NSLocale. So it is very easy to setup and implement different databases, which is great, but now I am confused about how I can implement my in app purchase model. Sorry about the long winded intro, here is my question: Is it possible to have an in app purchase add a line to my info.plist file? Or if not, is it possible to have the purchase reveal a new and updated plist file altogether that I would have already setup correctly? Any help here would be appreciated. Thanks

  • Memory leak when using Workflow 4.0 SqlWorkflowInstanceStore and PersistableIdleAction.Unload

    - by Rohland
    Hi, This particular problem is driving me nuts. I wonder if anyone has experienced a similar problem. If I load up a workflow then unload it and perform a memory snapshot then the result is predictable - my workflow is no longer in memory. However, if I load up a workflow and set the PersistableIdle action to PersistableIdleAction.Unload and let the workflow idle the workflow remains in memory even though the Unload action fires. I used ANTS Memory Profiler to debug this issue. This is the object retention graph outputted showing that an internal object is hanging onto my workflow instance. Can anyone else verify this problem? My code amounts to the following: Create SqlWorkflowInstanceStore and setup lock owner handle -- At this point I take a memory snapshot Create an instance of Workflow1 Set the PersistableIdle action Apply the instancestore to Workflow1 Setup action event handlers for Idle, Unload, UnhandledException etc. Persist the workflow instance Run the workflow instance Wait for instance to idle (caused by Delay activity) Ensure the Unload action is fired -- At this point I take a second memory snapshot From the above image, it is clear that the only object referencing Workflow1 is some internal event handlers result which I have no ability to dispose of. Any clues?

  • Winforms: Attempted to read or write protected memory. This is often an indication that other memory is corrupt

  • Call asp.net mvc Html Helper within custom html helper with expression parameter

    - by Frank Michael Kraft
    I am trying to write an html helper extension within the asp.net mvc framework. public static MvcHtmlString PlatformNumericTextBoxFor<TModel>(this HtmlHelper instance, TModel model, Expression<Func<TModel,double>> selector) where TModel : TableServiceEntity { var viewModel = new PlatformNumericTextBox(); var func = selector.Compile(); MemberExpression memExpession = (MemberExpression)selector.Body; string name = memExpession.Member.Name; var message = instance.ValidationMessageFor<TModel, double>(selector); viewModel.name = name; viewModel.value = func(model); viewModel.validationMessage = String.Empty; var result = instance.Partial(typeof(PlatformNumericTextBox).Name, viewModel); return result; } The line var message = instance.ValidationMessageFor<TModel, double>(selector); has a syntax error. But I do not understand it. The error is: Fehler 2 "System.Web.Mvc.HtmlHelper" enthält keine Definition für "ValidationMessageFor", und die Überladung der optimalen Erweiterungsmethode "System.Web.Mvc.Html.ValidationExtensions.ValidationMessageFor(System.Web.Mvc.HtmlHelper, System.Linq.Expressions.Expression)" weist einige ungültige Argumente auf. C:\Projects\WorkstreamPlatform\WorkstreamPlatform_WebRole\Extensions\PlatformHtmlHelpersExtensions.cs 97 27 WorkstreamPlatform_WebRole So according to the message, the parameter is invalid. But the method is actually declared like this: public static MvcHtmlString ValidationMessageFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression); So actually it should work.

  • Presenting UINavigationController modally -- problem setting up tool and nav bar items in root view controller viewDidLoad

    - by Bogatyr
    In my iOS app I'm creating and presenting a UINavigationController modally like so: MyViewController *myvc = [[[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil] autorelease]; UINavigationController *navVC = [[[UINavigationController alloc] initWithRootViewController:myvc] autorelease]; [self presentModalViewController:navVC animated:YES]; In the MyViewController viewDidLoad I'm creating and setting toolbar items for the navigation controller's toolbar, like so: self.navigationController.toolbar.items = [NSArray arrayWithObjects:(items...), nil]; the problem I'm having is that the items don't show up. If instead I call a method from MyViewController's viewDidLoad method that adds the toolbar items via performSelector:withObject:afterDelay:0, then it works perfectly. So there's obviously some race condition going on here with the initial presentation of the UINavigationController, initialization of its toolbar/navbar, and the initialization of the nav bar's specified initial root view controller. I verified in the debugger that the root view controller's viewDidLoad is called after the UINavigationController's viewDidLoad method. In fact, the root view controller's viewDidLoad method is not called until presentModalViewController: is called, and the UINavigationController's viewDidLoad is called within initWithRootViewController, so doesn't that imply that the UINavigationController object should be "all ready to go", including its nav bar and toolbars? I thought at first that the navigation controller's toolbar object may not exist yet at MyViewController's viewDidLoad time, but it clearly does. At least, NSLog shows that it is not nil during MyViewController's viewDidLoad method. In fact, the UINavigationController's toolbar object is identical at both times: in the root view controller's viewDidLoad, and in the "setupToolbar" method that I called with performSelector:withObject:afterDelay, so it's not getting "re-initialized" somehow. So, what's going on here? Why aren't my toolbar modifications "sticking" in MyViewController's viewDidLoad, and why does performing them in the next iteration of the runloop (performSelector:withObject:afterDelay:0) make it work? What is the "right" way of setting up initial navbar / toolbar items in code from the rootViewController of the UINavigationController?

  • Sharp architecture; Accessing Validation Results

    - by nabeelfarid
    I am exploring Sharp Architecture and I would like to know how to access the validation results after calling Entity.IsValid(). I have two scenarios e.g. 1) If the entity.IsValid() return false, I would like to add the errors to ModelState.AddModelError() collection in my controller. E.g. in the Northwind sample we have an EmployeesController.Create() action when we do employee.IsValid(), how can I get access to the errors? public ActionResult Create(Employee employee) { if (ViewData.ModelState.IsValid && employee.IsValid()) { employeeRepository.SaveOrUpdate(employee); } // .... } [I already know that when an Action method is called, modelbinder enforces validation rules(nhibernate validator attributes) as it parses incoming values and tries to assign them to the model object and if it can't parse the incoming values  then it register those as errors in modelstate for each model object property. But what if i have some custom validation. Thats why we do ModelState.IsValid first.] 2) In my test methods I would like to test the nhibernate validation rules as well. I can do entity.IsValid() but that only returns true/ false. I would like to Assert against the actual error not just true/ false. In my previous projects, I normally use a wrapper Service Layer for Repositories, and instead of calling Repositories method directly from controller, controllers call service layer methods which in turn call repository methods. In my Service Layer all my custom validation rules resides and Service Layer methods throws a custom exception with a NameValueCollection of errors which I can easily add to ModelState in my controller. This way I can also easily implement sophisticated business rules in my service layer as well. I kow sharp architecture also provides a Service Layer project. But what I am interested in and my next question is: How I can use NHibernate Vaidators to implement sophisticated custom business rules (not just null,empty, range etc.) and make Entity.IsValid() to verify those rules too ?

  • Understanding the Silverlight Dispatcher

    - by Matt
    I had a Invalid Cross Thread access issue, but a little research and I managed to fix it by using the Dispatcher. Now in my app I have objects with lazy loading. I'd make an Async call using WCF and as usual I use the Dispatcher to update my objects DataContext, however it didn't work for this scenario. I did however find a solution here. Here's what I don't understand. In my UserControl I have code to call an Toggle method on my object. The call to this method is within a Dispatcher like so. Dispatcher.BeginInvoke( () => _CurrentPin.ToggleInfoPanel() ); As I mentioned before this was not enough to satisfy Silverlight. I had to make another Dispatcher call within my object. My object is NOT a UIElement, but a simple class that handles all its own loading/saving. So the problem was fixed by calling Deployment.Current.Dispatcher.BeginInvoke( () => dataContext.Detail = detail ); within my class. Why did I have to call the Dispatcher twice to achieve this? Shouldn't a high-level call be enough? Is there a difference between the Deployment.Current.Dispatcher and the Dispatcher in a UIElement?

  • Extra white space, on HTML output, on PHP MVC

    - by user316841
    Hi, I'm getting extra white space, that is not CSS, or nothing like it on the view output: The HTML. I've checked for ? (removed, where I could), saved UTF8 without BOM. Checked for existent white space in the beginning of each file, even at end. This is the structure: index.php - this is the entry point; MODEL/ CONTROLLER/ VIEW/ Let's say, that trough method GET, its sent the var TPL with some value. Let's call it LIST, so it pulls the LIST model, with all data and then show the right template to the user, with the right data. I used and tested, with require_once, include_once, include, even tested with readfile (just to test). The LIST Template opens the header.tpl and footer.tpl; I also tryed to remove this both includes from LIST template, but still, the extra white space continued. This is where the extra white space is coming from. This controller is placed between controller activity runs here , this is where the extra white space is coming from: $model_works-getRows(); $rows = $model_works-rows; if ( !require_once('views/list_works.tpl.php') ) { echo "Error."; } // end if clause The list_works.tpl.php, is basicly HTML with tags; I've t tested by changing the extension to something else, like html. Also, just to remember that at top of this file, we are using require_once to open the header.tpl and at bottom the footer.tpl. I've tested by removing both and the extra white space was still generated. The extra white space is being generated here: EXTRA WHITE SPACE HERE Thanks a lot for looking, ;D

  • Hibernate: "Field 'id' doesn't have a default value"

    Hi, all. I'm facing what I think is a simple problem with Hibernate, but can't get over it (Hibernate forums being unreachable certainly doesn't help). I have a simple class I'd like to persist, but keep getting: SEVERE: Field 'id' doesn't have a default value Exception in thread "main" org.hibernate.exception.GenericJDBCException: could not insert: [hibtest.model.Mensagem] at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:103) at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:91) [ a bunch more ] Caused by: java.sql.SQLException: Field 'id' doesn't have a default value [ a bunch more ] The relevant code for the persisted class is: package hibtest.model; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.Inheritance; import javax.persistence.InheritanceType; @Entity @Inheritance(strategy = InheritanceType.JOINED) public class Mensagem { protected Long id; protected Mensagem() { } @Id @GeneratedValue public Long getId() { return id; } public Mensagem setId(Long id) { this.id = id; return this; } } And the actual running code is just plain: SessionFactory factory = new AnnotationConfiguration() .configure() .buildSessionFactory(); { Session session = factory.openSession(); Transaction tx = session.beginTransaction(); Mensagem msg = new Mensagem("YARR!"); session.save(msg); tx.commit(); session.close(); } I tried some "strategies" within the GeneratedValue annotation but it just doesn't seem to work. Initializing id doesn't help either! (eg Long id = 20L). Could anyone shed some light? EDIT 2: confirmed: messing with@GeneratedValue(strategy = GenerationType.XXX) doesn't solve it SOLVED: recreating the database solved the problem

  • Gridview sorting: SortDirection always Ascending

    - by Julien N
    Hi ! I have a gridview and I need to sort its elements when the user clicks on the header. Its datasource is a List object. The aspx is defined this way : <asp:GridView ID="grdHeader" AllowSorting="true" AllowPaging="false" AutoGenerateColumns="false" Width="780" runat="server" OnSorting="grdHeader_OnSorting" EnableViewState="true"> <Columns> <asp:BoundField DataField="Entitycode" HeaderText="Entity" SortExpression="Entitycode" /> <asp:BoundField DataField="Statusname" HeaderText="Status" SortExpression="Statusname" /> <asp:BoundField DataField="Username" HeaderText="User" SortExpression="Username" /> </Columns> </asp:GridView> The code behind is defined this way : First load : protected void btnSearch_Click(object sender, EventArgs e) { List<V_ReportPeriodStatusEntity> items = GetPeriodStatusesForScreenSelection(); this.grdHeader.DataSource = items; this.grdHeader.DataBind(); } when the user clicks on headers : protected void grdHeader_OnSorting(object sender, GridViewSortEventArgs e) { List<V_ReportPeriodStatusEntity> items = GetPeriodStatusesForScreenSelection(); items.Sort(new Helpers.GenericComparer<V_ReportPeriodStatusEntity>(e.SortExpression, e.SortDirection)); grdHeader.DataSource = items; grdHeader.DataBind(); } My problem is that e.SortDirection is always set to Ascending. I have webpage with a similar code and it works well, e.SortDirection alternates between Ascending and Descending. What did I do wrong ?

  • Milliseconds in DateTime.Now on .NET Compact Framework always zero? [SOLVED]

    - by Marcel
    Hi all, i want to have a time stamp for logs on a Windows Mobile project. The accuracy must be in the range a hundred milliseconds at least. However my call to DateTime.Now returns a DateTime object with the Millisecond property set to zero. Also the Ticks property is rounded accordingly. How to get better time accuracy? Remember, that my code runs on on the Compact Framework, version 3.5. I use a HTC touch Pro 2 device. Based on the answer from MusiGenesis i have created the following class which solved this problem: /// <summary> /// A more precisely implementation of some DateTime properties on mobile devices. /// </summary> /// <devdoc>Tested on a HTC Touch Pro2.</devdoc> public static class DateTimePrecisely { /// <summary> /// Remembers the start time when this model was created. /// </summary> private static DateTime _start = DateTime.Now; /// <summary> /// Remembers the system uptime ticks when this model was created. This /// serves as a more precise time provider as DateTime.Now can do. /// </summary> private static int _startTick = Environment.TickCount; /// <summary> /// Gets a DateTime object that is set exactly to the current date and time on this computer, expressed as the local time. /// </summary> /// <returns></returns> public static DateTime Now { get { return _start.AddMilliseconds(Environment.TickCount - _startTick); } } }

  • How can I test blades in MVC Turbine with Rhino Mocks?

    - by Brandon Linton
    I'm trying to set up blade unit tests in an MVC Turbine-derived site. The problem is that I can't seem to mock the IServiceLocator interface without hitting the following exception: System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) at System.Reflection.Emit.TypeBuilder._TermCreateClass(Int32 handle, Module module) at System.Reflection.Emit.TypeBuilder.CreateTypeNoLock() at System.Reflection.Emit.TypeBuilder.CreateType() at Castle.DynamicProxy.Generators.Emitters.AbstractTypeEmitter.BuildType() at Castle.DynamicProxy.Generators.Emitters.AbstractTypeEmitter.BuildType() at Castle.DynamicProxy.Generators.InterfaceProxyWithTargetGenerator.GenerateCode(Type proxyTargetType, Type[] interfaces, ProxyGenerationOptions options) at Castle.DynamicProxy.DefaultProxyBuilder.CreateInterfaceProxyTypeWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateInterfaceProxyTypeWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateInterfaceProxyWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options, IInterceptor[] interceptors) at Rhino.Mocks.MockRepository.MockInterface(CreateMockState mockStateFactory, Type type, Type[] extras) at Rhino.Mocks.MockRepository.CreateMockObject(Type type, CreateMockState factory, Type[] extras, Object[] argumentsForConstructor) at Rhino.Mocks.MockRepository.Stub(Type type, Object[] argumentsForConstructor) at Rhino.Mocks.MockRepository.<>c__DisplayClass1`1.<GenerateStub>b__0(MockRepository repo) at Rhino.Mocks.MockRepository.CreateMockInReplay<T>(Func`2 createMock) at Rhino.Mocks.MockRepository.GenerateStub<T>(Object[] argumentsForConstructor) at XXX.BladeTest.SetUp() Everything I search for regarding this error leads me to 32-bit vs. 64-bit DLL compilation issues, but MVC Turbine uses the service locator facade everywhere and we haven't had any other issues, just with using Rhino Mocks to attempt mocking it. It blows up on the second line of this NUnit set up method: IRotorContext _context; IServiceLocator _locator; [SetUp] public void SetUp() { _context = MockRepository.GenerateStub<IRotorContext>(); _locator = MockRepository.GenerateStub<IServiceLocator>(); _context.Expect(x => x.ServiceLocator).Return(_locator); } Just a quick aside; I've tried implementing a fake implementing IServiceLocator, thinking that I could just keep track of calls to the type registration methods. This won't work in our setup, because we extend the service locator's interface in such a way that if the type isn't Unity-based, the registration logic is not invoked.

  • RhinoMocks Testing callback method

    - by joblot
    Hi All I have a service proxy class that makes asyn call to service operation. I use a callback method to pass results back to my view model. Doing functional testing of view model, I can mock service proxy to ensure methods are called on the proxy, but how can I ensure that callback method is called as well? With RhinoMocks I can test that events are handled and event raise events on the mocked object, but how can I test callbacks? ViewModel: public class MyViewModel { public void GetDataAsync() { // Use DI framework to get the object IMyServiceClient myServiceClient = IoC.Resolve<IMyServiceClient>(); myServiceClient.GetData(GetDataAsyncCallback); } private void GetDataAsyncCallback(Entity entity, ServiceError error) { // do something here... } } ServiceProxy: public class MyService : ClientBase, IMyServiceClient { // Constructor public NertiAdminServiceClient(string endpointConfigurationName, string remoteAddress) : base(endpointConfigurationName, remoteAddress) { } // IMyServiceClient member. public void GetData(Action<Entity, ServiceError> callback) { Channel.BeginGetData(EndGetData, callback); } private void EndGetData(IAsyncResult result) { Action<Entity, ServiceError> callback = result.AsyncState as Action<Entity, ServiceError>; ServiceError error; Entity results = Channel.EndGetData(out error, result); if (callback != null) callback(results, error); } } Thanks

  • Configuration Error ASP.NET password format specified is invalid

    - by salvationishere
    I am getting the above error in IIS 6.0 now when I browse my C# / SQL web application. This was built in VS 2008 and SS 2008 on a 32-bit XP OS. The application was working before I added Login controls to it. However, this is my first time configuring Login/password controls so I am probably missing something really basic. This error doesn't happen until I try to login. Here are the details of my error from IIS; I get the same error in VS: Parser Error Message: Password format specified is invalid.
