  • filterSecurityInterceptor and metadatasource implementation spring-security

    - by Mike
    Hi! I created a class that implements the FilterInvocationSecurityMetadataSource interface. I implemented it like this: public List<ConfigAttribute> getAttributes(Object object) { FilterInvocation fi = (FilterInvocation) object; Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal(); Long companyId = ((ExtenededUser) principal).getCompany().getId(); String url = fi.getRequestUrl(); // String httpMethod = fi.getRequest().getMethod(); List<ConfigAttribute> attributes = new ArrayList<ConfigAttribute>(); FilterSecurityService service = (FilterSecurityService) SpringBeanFinder.findBean("filterSecurityService"); Collection<Role> roles = service.getRoles(companyId); for (Role role : roles) { for (View view : role.getViews()) { if (view.getUrl().equalsIgnoreCase(url)) attributes.add(new SecurityConfig(role.getName() + "_" + role.getCompany().getName())); } } return attributes; } when I debug my application I see it reaches this class, it only reaches getAllConfigAttributes method, that is empty as I said, and return null. after that it prints this warning: Could not validate configuration attributes as the SecurityMetadataSource did not return any attributes from getAllConfigAttributes(). My aplicationContext- security is like this: <beans:bean id="filterChainProxy" class="org.springframework.security.web.FilterChainProxy"> <filter-chain-map path-type="ant"> <filter-chain filters="sif,filterSecurityInterceptor" pattern="/**" /> </filter-chain-map> </beans:bean> <beans:bean id="filterSecurityInterceptor" class="org.springframework.security.web.access.intercept.FilterSecurityInterceptor"> <beans:property name="authenticationManager" ref="authenticationManager" /> <beans:property name="accessDecisionManager" ref="accessDecisionManager" /> <beans:property name="securityMetadataSource" ref="filterSecurityMetadataSource" /> </beans:bean> <beans:bean id="filterSecurityMetadataSource" class="com.mycompany.filter.FilterSecurityMetadataSource"> </beans:bean> what could be the problem?

  • Why my UTableView with style UITableViewStyleGrouped is consuming memory?

    - by prathumca
    Hello everyone, Currently in my app, I'm using an UITableView with style UITableViewStyleGrouped as shown below. CGRect imgFrame = CGRectMake(0, 0, 320, 650); UITableView *myTable = [[UITableView alloc] initWithFrame:imgFrame style:UITableViewStyleGrouped]; myTable.dataSource = self; myTable.delegate = self; //make the current object the event handler for view [self.view addSubview:myTable]; [myTable release]; And the data has stored in an array "dataArray". dataArray has collection of arrays, where each array represent a section. Currently I have only one section with 100 records. When I installed my app onto my IPhone, I observed that this UITableView is consuming 20 MB of IPhone memory. If I changed the table view style to "UITableViewStylePlain", then it is consuming only 4MB of memory. I'm trying to figure it out, where is the exact problem, but not. What was wrong with "UITableViewStyleGrouped"? Regards, prathumca.

  • How to use will_paginate with a nested resource in Rails?

    - by Sue Petersen
    I'm new to Rails, and I'm having major trouble getting will_paginate to work with a nested resource. I have two models, Statement and Invoice. will_paginate is working on Statement, but I can't get it to work on Invoice. I know I'd doing something silly, but I can't figure it out and the examples I've found on google won't work for me. statement.rb class Statement < ActiveRecord::Base has_many :invoices def self.search(search, page) paginate :per_page => 19, :page => page, :conditions => ['company like ?', "%#{search}%"], :order => 'date_due DESC, company, supplier' end end statements_controller.rb <irrelevant code clipped for readability> def index #taken from the RAILSCAST 51, will_paginate podcast @statements = Statement.search(params[:search], params[:page]) end I call this in the view like so, and it works: <%= will_paginate @statements %> But I can't figure out how to get it to work for Invoices: invoice.rb class Invoice < ActiveRecord::Base belongs_to :statement def self.search(search, page) paginate :per_page => 19, :page => page, :conditions => ['company like ?', "%#{search}%"], :order => 'employee' end end invoices_controller.rb class InvoicesController < ApplicationController before_filter :find_statement #TODO I can't get will_paginate to work w a nested resource def index #taken from the RAILSCAST 51, will_paginate podcast @invoices = Invoice.search(params[:search], params[:page]) end def find_statement @statement_id = params[:statement_id] return(redirect_to(statements_url)) unless @statement_id @statement = Statement.find(@statement_id) end end And I try to call it like this: <%= will_paginate (@invoices) % The most common error message, as I play with this, is: "The @statements variable appears to be empty. Did you forget to pass the collection object for will_paginate?" I don't have a clue what the problem is, or how to fix it. Thanks for any help and guidance!

  • Ajax model binding of a complex type

    - by David G
    I am trying to do something along the lines of the following where I have a Controller with an method similar to: public ActionResult Insert(Author author) { //do something... } Where the Author type looks like: public class Author { public string FirstName { get; set; } public string LastName { get; set; } public Book[] Books { get; set; } public Author() { Books = new Book[0]; } } public class Book { public string Title { get; set; } public int NumberOfPages { get; set; } } From a page I want to submit data using JQuery and Ajax something like function addAuthor() { var auth = { 'FirstName': 'Roald', 'LastName': 'Dahl', 'Books': [ { 'Title': 'Charlie and the Chocolate Factory', 'NumberOfPages': 264 }, { 'Title': 'The Twits', 'NumberOfPages': 316 } ] }; $.ajax({ type: "GET", url: "/Insert", data: auth }); } MVC binds the Author object (FirstName and LastName are set) but doesn't bind the Books property. Why is that and how can I submit an object containing an Array (or a Collection) as a property through AJAX?

  • ASP.NET Event delegation between user controls

    - by Ishan
    Give the following control hierarchy on a ASP.NET page: Page HeaderControl       (User Control) TitleControl       (Server Control) TabsControl       (User Control) other controls I'm trying to raise an event (or some notification) in the TitleControl that bubbles to the Page level. Then, I'd like to (optionally) register an event handler at the Page codebehind that will take the EventArgs and modify the TabsControl in the example above. The important thing to note is that this design will allow me to drop these controls into any Page and make the entire system work seamlessly if the event handler is wired up. The solution should not involve a call to FindControl() since that becomes a strong association. If no handler is defined in the containing Page, the event is still raised by TitleControl but is not handled. My basic goal is to use event-based programming so that I can decouple the user controls from each other. The event from TitleControl is only raised in some instances, and this seemed to be (in my head) the preferred approach. However, I can't seem to find a way to cleanly achieve this. Here are my (poor) attempts: Using HttpContext.Current.Items Add the EventArgs to the Items collection on TitleControl and pick it up on the TabsControl. This works but it's fundamentally hard to decipher since the connection between the two controls is not obvious. Using Reflection Instead of passing events, look for a function on the container Page directly within TitleControl as in: Page.GetType().GetMethod("TabControlHandler").Invoke(Page, EventArgs); This will work, but the method name will have to be a constant that all Page instances will have to defined verbatim. I'm sure that I'm over-thinking this and there must be a prettier solution using delegation, but I can't seem to think of it. Any thoughts?

  • Can FluentNHibernate be used with .Net4?

    - by stiank81
    I have a WPF application running with .Net3.5 using FluentNHibernate, and all works fine. When I upgraded to VS2010 I ran into some odd problems, but after changing to use x64 variant of SQLite it worked fine again. Now I want to change to use .Net4, but this has turned into a more painful experience then I expected.. First I met a problem which required that I set a [SecurityCritical] attribute. Fine - I fixed this. But the reason this was exposed was because an exception was thrown in the first place. And the exception thrown was the following - when calling FluentConfiguration.BuildConfiguration: FluentConfigurationException unhandled An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail The inner exception gives us more information: Message = "Could not create the driver from NHibernate.Driver.SQLite20Driver, NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4." This is what I saw in my own project when moving to VS2010. I have tried changing Fluent to use the x64 variant of SQLite, but this doesn't change anything. Does it sound like it might be related to mixing of 32bit and 64bit assemblies? I see that there are also others that have seen this problem, but I haven't really seen any solution yet. Anyone out there using Fluent with .Net4 and SQLite - on a 64bit machine - successfully? Help! I'm lost...

  • Does NHibernate LINQ support ToLower() in Where() clauses?

    - by Daniel T.
    I have an entity and its mapping: public class Test { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual string Description { get; set; } } public class TestMap : EntityMap<Test> { public TestMap() { Id(x => x.Id); Map(x => x.Name); Map(x => x.Description); } } I'm trying to run a query on it (to grab it out of the database): var keyword = "test" // this is coming in from the user keyword = keyword.ToLower(); // convert it to all lower-case var results = session.Linq<Test> .Where(x => x.Name.ToLower().Contains(keyword)); results.Count(); // execute the query However, whenever I run this query, I get the following exception: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Am I right when I say that, currently, Linq to NHibernate does not support ToLower()? And if so, is there an alternative that allows me to search for a string in the middle of another string that Linq to NHibernate is compatible with? For example, if the user searches for kap, I need it to match Kapiolani, Makapuu, and Lapkap.

  • Expression Tree with Property Inheritance causes an argument exception

    - by Adam Driscoll
    Following this post: link text I'm trying to create an expression tree that references the property of a property. My code looks like this: public interface IFoo { void X {get;set;} } public interface IBar : IFoo { void Y {get;set;} } public interface IFooBarContainer { IBar Bar {get;set;} } public class Filterer { //Where T = "IFooBarContainer" public IQueryable<T> Filter<T>(IEnumerable<T> collection) { var argument = Expression.Parameter(typeof (T), "item"); //... //where propertyName = "IBar.X"; PropertyOfProperty(argument, propertyName); } private static MemberExpression PropertyOfProperty(Expression expr, string propertyName) { return propertyName.Split('.').Aggregate<string, MemberExpression>(null, (current, property) => Expression.Property(current ?? expr, property)); } } I receive the exception: System.ArgumentException: Instance property 'X' is not defined for type 'IBar' ReSharper turned the code in the link above into the condensed statement in my example. Both forms of the method returned the same error. If I reference IBar.Y the method does not fail.

  • After rewrite Model sales/order_collection it works except in Admin section, why?

    - by latvian
    Hi, I rewrite the sales/order_collection Model or, perhaps, correctly said the Resource. I did that to add filter that filters orders by store_ids. Please see my post to see how i did it http://stackoverflow.com/questions/2426986/how-to-rewrite-collection My new model works and here is how i tested $path = '../magento'; require_once('app/Mage.php'); umask(0); $app = Mage::app('base','website'); $col = Mage::getResourceModel('sales/order_collection')->addAttributeToSelect('*'); echo "<br>Size of the colletion: ".$col->getSize(); This new Model filters and returns # of orders just like i want. It returns # of orders also when i run it inside any of my created modules, but not in Admin section then it returns 0 orders In Admin section the same line is called as above ( Mage::getResourceModel('sales/order_collection')-addA....) from Mage_Adminhtml_Block_Sales_Order_Grid class (line 50) . It can be initiated when going Admin-Sales-Orders. However, it is returning 0 orders instead of # of orders How is it that the new Model returns orders anywhere else but from Admin section? What is done differently in Admin section?..please help. I have spent hours and hours and any pointers will help Thank you, Margots

  • MVVM Light - master / child views and dependency properties

    - by Carl Dickinson
    I'm getting an odd problem when implementing a master / child view and custom dependency properties. Within my master view I'm binding the view model declaratively in the XAML as follows: DataContext="{Binding MainViewModelProperty, Source={StaticResource Locator}}" and my MainViewModel is exposing an observable collection which I'm binding to an ItemsControl as follows: <ItemsControl ItemsSource="{Binding Lists}" Height="490" Canvas.Top="10" Width="70"> <ItemsControl.ItemTemplate> <DataTemplate> <Canvas> <local:TaskListControl Canvas.Left="{Binding ListLeft}" Canvas.Top="{Binding ListTop}" Width="{Binding ListWidth}" Height="{Binding ListHeight}" ListDetails="{Binding}"/> </Canvas> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> TaskListControl in turn declares and bind to it's ViewModel and I've also defined a dependency property for the ListDetails property. The ListDetails property is not being set and if I remove the declarative reference to it's viewmodel the dependency property's callback does get fired. Is there a conflict with declaratively binding to viewmodels and definig dependency properties? I really like MVVM Light's blendability and want to perserve with this problem so any help would be apprectiated. If you'd like to receive the source for my project then please ask

  • Unexpected Event Behavior When Using VB6 with COM Interop (C#)

    - by Randal
    We are using a COM Interop (C#) to allow for a VB6 application to send data to a server. Once the server receives the data, the managed code will raise a DataSent event. This event is only fired after a correlation ID is returned to the original caller. About 1% of the time, we've encountered VB6 executing the raised event before finishing the function that originally sent the data. Using the following code: ' InteropTester.COMEvents is the C# object ' Dim WithEvents m_ManagedData as InteropTester.COMEvents Private Sub send_data() Set m_ManagedData = new COMEvents Dim id as Integer ' send 5 to using the managed interop object ' id = m_ManagedData.SendData(5) LogData "ID " & id & " was returned" m_correlationIds.Add id End Sub Private Sub m_ManagedData_DataSent(ByVal sender as Variant, ByVal id as Integer) LogData "Data was successfully sent to C#" ' check if the returned ID is in the m_correlationIds collection goes here' End Sub We can verify that the id is returned with a value when we call m_ManagedData.SendData(5), but the logs then show that the m_ManagedData_DataSent is occasionally called before send_data ends. How is possible for VB6 to access the Message Loop to know that the DataSent event was raised before exiting send_data()? We are not calling DoEvents and everything within VB6 is synchronous. Thanks in advance for your help.

  • How to avoid loading a LINQ to SQL object twice when editting it on a website.

    - by emzero
    Hi guys I know you are all tired of this Linq-to-Sql questions, but I'm barely starting to use it (never used an ORM before) and I've already find some "ugly" things. I'm pretty used to ASP.NET Webforms old school developing, but I want to leave that behind and learn the new stuff (I've just started to read a ASP.NET MVC book and a .NET 3.5/4.0 one). So here's is one thing I didn't like and I couldn't find a good alternative to it. In most examples of editing a LINQ object I've seen the object is loaded (hitting the db) at first to fill the current values on the form page. Then, the user modify some fields and when the "Save" button is clicked, the object is loaded for second time and then updated. Here's a simplified example of ScottGu NerdDinner site. // // GET: /Dinners/Edit/5 [Authorize] public ActionResult Edit(int id) { Dinner dinner = dinnerRepository.GetDinner(id); return View(new DinnerFormViewModel(dinner)); } // // POST: /Dinners/Edit/5 [AcceptVerbs(HttpVerbs.Post), Authorize] public ActionResult Edit(int id, FormCollection collection) { Dinner dinner = dinnerRepository.GetDinner(id); UpdateModel(dinner); dinnerRepository.Save(); return RedirectToAction("Details", new { id=dinner.DinnerID }); } As you can see the dinner object is loaded two times for every modification. Unless I'm missing something about LINQ to SQL caching the last queried objects or something like that I don't like getting it twice when it should be retrieved only one time, modified and then comitted back to the database. So again, am I really missing something? Or is it really hitting the database twice (in the example above it won't harm, but there could be cases that getting an object or set of objects could be heavy stuff). If so, what alternative do you think is the best to avoid double-loading the object? Thank you so much, Greetings!

  • How can I save an entire list of items true or false?

    - by JZ
    I'm following Ryan Bates, Railscast episode 52 and I've translated relevant parts of the code to work with Rails 3.0.0.beta2. In Ryan's case, he simply marks items incomplete and saves a timestamp. If an Item contains a timestamp the model returns the item in the completed list. I'm attempting to save ALL values true or false, depending on whether the check_box_tag is selected or not (using boolean). I am able to save ONLY selected items, true or false. How can I save an entire list of items true or false, depending on whether the checkbox is selected? The following is my attempt: controller logic: def yardsign Add.update_all(["yardsign=?", true], :id => params[:yard_ids]) redirect_to adds_path end html.erb: <%= form_tag yardsign_adds_path, :method => :put do %> <% @adds.each do |add| %> <td><%= check_box_tag "yard_ids[]", add.id %></td> <% end %> <% end %> routes.rb resources :adds do collection do put :yardsign end end Terminal Started POST "/adds/yardsign" for 127.0.0.1 at 2010-04-15 19:22:49 Processing by AddsController#yardsign as HTML Parameters: {"commit"=>"Update", "yardsigntakers"=>["1", "2"], "authenticity_token"=>"3arhsxg/Ky+0W7RNM2T3QditMTJmOnLR5CqmMYWN4Qw="} User Load (0.3ms) SELECT "users".* FROM "users" WHERE ("users"."id" = 1) LIMIT 1 SQL (1.8ms) UPDATE "adds" SET yardsign='t' WHERE ("adds"."id" IN (1, 2)) Redirected to http://localhost:3000/adds

  • WPF, C# - Making Intellisense/Autocomplete list, fastest way to filter list of strings

    - by user559548
    Hello everyone, I'm writing an Intellisense/Autocomplete like the one you find in Visual Studio. It's all fine up until when the list contains probably 2000+ items. I'm using a simple LINQ statement for doing the filtering: var filterCollection = from s in listCollection where s.FilterValue.IndexOf(currentWord, StringComparison.OrdinalIgnoreCase) >= 0 orderby s.FilterValue select s; I then assign this collection to a WPF Listbox's ItemSource, and that's the end of it, works fine. Noting that, the Listbox is also virtualised as well, so there will only be at most 7-8 visual elements in memory and in the visual tree. However the caveat right now is that, when the user types extremely fast in the richtextbox, and on every key up I execute the filtering + binding, there's this semi-race condition, or out of sync filtering, like the first key stroke's filtering could still be doing it's filtering or binding work, while the fourth key stroke is also doing the same. I know I could put in a delay before applying the filter, but I'm trying to achieve a seamless filtering much like the one in Visual Studio. I'm not sure where my problem exactly lies, so I'm also attributing it to IndexOf's string operation, or perhaps my list of string's could be optimised in some kind of index, that could speed up searching. Any suggestions of code samples are much welcomed. Thanks.

  • Overriding equals method without breaking symmetry in a class that has a primary key

    - by Kosta
    Hi, the answer to this question is probably "not possible", but let me ask regardless :) Assuming we have a very simple JAVA class that has a primary key, for example: class Person { String ssid; String name; String address; ... } Now, I want to store people in a collection, meaning I will have to override the equals method. Not a completely trivial matter, but on a bare basis I will have something along the lines of: @Override public boolean equals (Object other) { if(other==this) return true; if(!other.getClass().equals(this.getClass()) return false; Person otherPerson = (Person)other; if(this.ssid.equals(otherPerson.getSsid()) return true; } Excuse any obvious blunders, just typing this out of my head. Now, let's say later on in the application I have a ssid I obtained through user input. If I want to compare my ssid to a Person, I would have to call something like: String mySsid = getFromSomewhere(); Person myPerson = getFromSomewhere(); if(myPerson.equals(new Person(mySsid)) doSomething(); This means I have to create a convenience constructor to create a Person based on ssid (if I don't already have one), and it's also quite verbose. It would be much nicer to simply call myPerson.equals(mySsid) but if I added a string comparison to my Person equals class, that would break the symmetry property, since the String hasn't got a clue on how to compare itself to a Person. So finally, the big question, is there any way to enable this sort of "shorthand" comparisons using the overriden equals method, and without breaking the symmetry rule? Thanks for any thoughts on this!

  • WCF contracts - namespaces and SerializationExceptions

    - by qntmfred
    I am using a third party web service that offers the following calls and responses http://api.athirdparty.com/rest/foo?apikey=1234 <response> <foo>this is a foo</foo> </response> and http://api.athirdparty.com/rest/bar?apikey=1234 <response> <bar>this is a bar</bar> </response> This is the contract and supporting types I wrote [ServiceContract] [XmlSerializerFormat] public interface IFooBarService { [OperationContract] [WebGet( BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "foo?key={apikey}")] FooResponse GetFoo(string apikey); [OperationContract] [WebGet( BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "bar?key={apikey}")] BarResponse GetBar(string apikey); } [XmlRoot("response")] public class FooResponse { [XmlElement("foo")] public string Foo { get; set; } } [XmlRoot("response")] public class BarResponse { [XmlElement("bar")] public string Bar { get; set; } } and then my client looks like this static void Main(string[] args) { using (WebChannelFactory<IFooBarService> cf = new WebChannelFactory<IFooBarService>("thirdparty")) { var channel = cf.CreateChannel(); FooResponse result = channel.GetFoo("1234"); } } When I run this I get the following exception Unable to deserialize XML body with root name 'response' and root namespace '' (for operation 'GetFoo' and contract ('IFooBarService', 'http://tempuri.org/')) using XmlSerializer. Ensure that the type corresponding to the XML is added to the known types collection of the service. If I comment out the GetBar operation from IFooBarService, it works fine. I know I'm missing an important concept here - just don't know quite what to look for. What is the proper way to construct my contract types, so that they can be properly deserialized?

  • SharePoint Designer Workflow: Unruly 'Collect User Data' Action

    - by Jeremy
    I'm a student in a SharePoint class online. This problem has riddled everyone I've discussed it with, including the teacher. There seems to be some sort of problem when I create a workflow with the collect data action. I can create workflows that send e-mails and use the other actions just fine. What could be causing this problem? My reproduction steps are simple: Create a new Site Collection with the Blank Site template. Create a new Custom List. In SharePoint Designer, start a new workflow on the Custom List. Add the collect data action to the workflow. Set the user to the one that created the task. Set the data to anything. A single check box, a string, Choice, doesn't matter. Leave the output variable as default. Mystery error appears! When the Check Workflow button is pressed, nothing happens. No message box appears at all. The warning icon in the Steps panel merely points out that there are some errors, it isn't specific as to what they are. Additionally, when I click on the data object again after it's been created, it doesn't populate the form with the old values. It goes back to the default name with no fields. So there's definitely something going wrong here. I've narrowed the problem down to the data object, but I don't know what to do about it. The workflow acts like normal for other activities. For example, delete the Collect Data action and add a Send Email one instead and it compiles and runs successfully.

  • Autocomplete Error Question - Ruby on Rails

    - by bgadoci
    I have built a very simple blog application using Ruby on Rails. New to both Ruby and Rails so excuse the stupid questions. I currently have two tables that relate to this question. I have a Post table and a Tag table. Basically I set it up such that Post has_many :tags and Tag belongs_to :post. I am using AJAX to process and display the tags in the show view of the post. I installed the auto_complete plugin and I am getting an error when I enter the letters in the text_field_with_auto_complete for tag creation. My suspicion is this is because the form is a remote_form_for or something I am doing wrong in the routes.rb. Here is the error and code: Error Processing PostsController#show (for 127.0.0.1 at 2010-04-13 23:25:46) [GET] Parameters: {"tag"=>{"tag_name"=>"f"}, "id"=>"auto_complete_for_tag_tag_name"} Post Load (0.1ms) SELECT * FROM "posts" WHERE ("posts"."id" = 0) ActiveRecord::RecordNotFound (Couldn't find Post with ID=auto_complete_for_tag_tag_name): app/controllers/posts_controller.rb:22:in `show' Rendered rescues/_trace (26.0ms) Rendered rescues/_request_and_response (0.2ms) Rendering rescues/layout (not_found) remote_form_for located in /views/posts/show.html.erb <% remote_form_for [@post, Tag.new] do |f| %> <p> <%= f.label :tag_name, "Tag" %><br/> <%= text_field_with_auto_complete :tag, :tag_name, {}, {:method => :get} %> </p> <p><%= f.submit "Add Comment" %></p> <% end %> tags_controller.rb (I'll spare you all the actions but added the following here) auto_complete_for :tag, :tag_name routes.rb map.resources :posts, :has_many => :comments map.resources :posts, :has_many => :tags map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get }

  • How do I change the CellErrorStyle for an Xceed Datagrid?

    - by Bob
    So in the Xceed documentation there is a code example that does not work for me. It may be because my grid is bound to a DataGridCollectionView. The objects in the collection used by the datagridcollection are what implement IDataErrorInfo. The errors are showing up just fine. The problem is that they are using the default orange background for errors...I need a red border. Below is the XAML instantiation of my grid. I set the DataCell background property to red just so I could be sure I had access to the grid's properties... I do. I just can't find the way to identify the cell's w/ errors so I can style them.

  • Show me your Linq to SQL architectures!

    - by Brad Heller
    I've been using Linq to SQL for a new implementation that I've been working on. I have about 5000 lines of code and am a little ways from a solid demo. I've been pretty satisfied with Linq to SQL so far -- the tools are excellent and pretty painless and it allows you to get a DAL up and running quickly. That said, there are some major draw backs that I just keep hitting over and over again. Namely how to handle separation of concerns between my DAL and my business layer and juggling that with different data contexts. Here is the architecture I've been using: My repositories do all my data access and they return Linq to SQL objects. Each of my Linq to SQL objects implements an IDetachable interface. A typical implementation looks like this: partial class PaymentDetail : IDetachable { #region IDetachable Members public bool IsAttached { get { return PropertyChanging != null; } } public void Detach() { if (IsAttached) { PropertyChanged = null; PropertyChanging = null; Transaction.Detach(); } } #endregion } Every time I do a DAL operation in my repository I "detach" when I'm done with the object (and it should theoretically detach from any child objects) to remove the DataContext's context. Like I said, this works pretty well, but there are some edge cases that seem to be a big pain in the ass. For instance, my Transaction object has many PaymentDetails. Even when there are no PaymentDetails in that collection it's still attached to the DataContext's context! Thus, if I try to update (I update by Attach()ing to the object and then SubmitChanges()) I get that dreaded "An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. This is not supported." message. Anyway, I'm starting to doubt that this technology was a good gamble. Has anyone got a decent architecture that they're willing to share? I'd really love to use this technology but I feel like I spend 1/3 of my time just debugging is retarded quirks!

  • JPA/Hibernate query with class name?

    - by Petteri Hietavirta
    In this example com.test.Cat extends com.test.Animal and there is no field DB in CAT table of com.test.Cat explicitly defining its type (it wasn't me). When I query my animals from DB I get a collection of Animals. It is possible to sort them by class name: order by r.class but is there a way to use class name as a criteria? For example I would like to get all animals expect dogs. But no luck - even this does not work: where r.class = ? (String "ccc.test.Cat") as I get an exception: Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer at org.hibernate.type.IntegerType.set(IntegerType.java:64) at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:154) at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:136) at org.hibernate.param.PositionalParameterSpecification.bind(PositionalParameterSpecification.java:62) at org.hibernate.loader.hql.QueryLoader.bindParameterValues(QueryLoader.java:514) at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1589) at org.hibernate.loader.Loader.doQuery(Loader.java:696) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:259) at org.hibernate.loader.Loader.doList(Loader.java:2228) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2125) at org.hibernate.loader.Loader.list(Loader.java:2120) at org.hibernate.loader.hql.QueryLoader.list(QueryLoader.java:401) at org.hibernate.hql.ast.QueryTranslatorImpl.list(QueryTranslatorImpl.java:361) at org.hibernate.engine.query.HQLQueryPlan.performList(HQLQueryPlan.java:196) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1148) at org.hibernate.impl.QueryImpl.list(QueryImpl.java:102) at org.hibernate.ejb.QueryImpl.getResultList(QueryImpl.java:67)

  • NSOutlineView/NSTreeController - calculate sum of column

    - by matei
    I have a NSOutlineView bound to a NSTreeController. My data items are a custom class , let's call them "Row", and suppose a Row contains a "name" and a numeric field called "number" . All these "Rows" are found in let's say a "RowContainer" which has a "rows" mutable array holding the parent (level 0) rows. Each row also has a "children" NSMutableArray member which holds it's children. I have this working, and I want to display under the outlineview a textfield with the sum of all the "number" values of the rows. I bound this textfield to a "total" property of the "RowContainer". Now the problem is how or from where to trigger the recalculation of the "total" property, since this involves a recursive walk on the tree of rows, and I always get a "Collection was mutated while being enumerated" error. I've tried making a method "recalculateTotal", and calling it from the "setNumber" method of the "Row" class , but same error occurs. If I put the recalculation logic in the "total" getter, I can't trigger it to do the math. I'm sure the solution is simple but I can't see it

  • Using Build Manager Class to Load ASPX Files and Populate its Controls

    - by Sandhurst
    I am using BuildManager Class to Load a dynamically generated ASPX File, please note that it does not have a corresponding .cs file. Using Following code I am able to load the aspx file, I am even able to loop through the control collection of the dynamically created aspx file, but when I am assigning values to controls they are not showing it up. for example if I am binding the value "Dummy" to TextBox control of the aspx page, the textbox remains empty. Here's the code that I am using protected void Page_Load(object sender, EventArgs e) { LoadPage("~/Demo.aspx"); } public static void LoadPage(string pagePath) { // get the compiled type of referenced path Type type = BuildManager.GetCompiledType(pagePath); // if type is null, could not determine page type if (type == null) throw new ApplicationException("Page " + pagePath + " not found"); // cast page object (could also cast an interface instance as well) // in this example, ASP220Page is a custom base page System.Web.UI.Page pageView = (System.Web.UI.Page)Activator.CreateInstance(type); // call page title pageView.Title = "Dynamically loaded page..."; // call custom property of ASP220Page //pageView.InternalControls.Add( // new LiteralControl("Served dynamically...")); // process the request with updated object ((IHttpHandler)pageView).ProcessRequest(HttpContext.Current); LoadDataInDynamicPage(pageView); } private static void LoadDataInDynamicPage(Page prvPage) { foreach (Control ctrl in prvPage.Controls) { //Find Form Control if (ctrl.ID != null) { if (ctrl.ID.Equals("form1")) { AllFormsClass cls = new AllFormsClass(); DataSet ds = cls.GetConditionalData("1"); foreach (Control ctr in ctrl.Controls) { if (ctr is TextBox) { if (ctr.ID.Contains("_M")) { TextBox drpControl = (TextBox)ctr; drpControl.Text = ds.Tables[0].Rows[0][ctr.ID].ToString(); } else if (ctr.ID.Contains("_O")) { TextBox drpControl = (TextBox)ctr; drpControl.Text = ds.Tables[1].Rows[0][ctr.ID].ToString(); } } } } } } }

  • Quick MEF + SL4 question

    - by Tom Allen
    I'm working on an app in the Silverlight 4 RC and i'm taking the oppertunity to learn MEF for handling plugin controls. I've got it working in a pretty basic manor, but it's not exactly tidy and I know there is a better way of importing multiple xap's. Essentially, in the App.xaml of my host app, I've got the following telling MEF to load my xap's: AggregateCatalog catalog = new AggregateCatalog(); DeploymentCatalog c1 = new DeploymentCatalog(new Uri("TestPlugInA.xap", UriKind.Relative)); DeploymentCatalog c2 = new DeploymentCatalog(new Uri("TestPlugInB.xap", UriKind.Relative)); catalog.Catalogs.Add(c1); catalog.Catalogs.Add(c2); CompositionHost.Initialize(catalog); c1.DownloadAsync(); c2.DownloadAsync(); I'm sure I'm not using the AggregateCatalog fully here and I need to be able to load any xap's that might be in the directory, not just hardcoding Uri's obviously.... Also, in the MainPage.xaml.cs in the host I have the following collection which MEF puts the plugin's into: [ImportMany(AllowRecomposition = true)] public ObservableCollection<IPlugInApp> PlugIns { get; set; } Again, this works, but I'm pretty sure I'm using ImportMany incorrectly.... Finally, the MainPage.xaml.cs file implements IPartImportsSatisfiedNotification and I have the following for handling the plugin's once loaded: public void OnImportsSatisfied() { sp.Children.Clear(); foreach (IPlugInApp plugIn in PlugIns) { if (plugIn != null) sp.Children.Add(plugIn.GetUserControl()); } } This works, but it seems filthy that it runs n times (n being the number of xap's to load). I'm having to call sp.Children.Clear() as if I don't, when loading the 2 plugin's, my stack panel is populated as follows: TestPlugIn A TestPlugIn A TestPlugIn B I'm clearly missing something here. Can anyone point out what I should be doing? Thanks!

  • Silverlight Toolkit ListBoxDragTarget Only One Way

    - by Tom Allen
    I've got a Silverlight 3 app that has two ListBoxes that I need to be able to drag items between. I've got the toolkit control working so that I can drag from ListBox lbA to ListBox lbB but i then can't drag the item from lbB back to lbA. <toolkit:ListBoxDragDropTarget mswindows:DragDrop.AllowDrop="True"> <ListBox x:Name="lbA" Style="{StaticResource ListBoxStyle}"> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding DisplayMember}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </toolkit:ListBoxDragDropTarget> <toolkit:ListBoxDragDropTarget mswindows:DragDrop.AllowDrop="True"> <ListBox x:Name="lbB" Style="{StaticResource ListBoxStyle}" Width="350"> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding DisplayMember}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </toolkit:ListBoxDragDropTarget> I'm binding lbA to an ObservableCollection of MyObject items which is a parent class for objects MyObjectA and MyObjectB (and there is a mix of ChildObjectA and ChildObjectB items). Is the one way behaviour I'm seeing due to binding to a collection MyObjects or something else i'm missing?
