  • Using FluentValidation with Castle Windsor and Entity Framework 4.0 (POCO) in MVC2

    - by Brian McCord
    This isn't a very simple question, but hopefully someone has run across it. I am trying to get the following things working together: MVC2 FluentValidation Entity Framework 4.0 (POCO) Castle Windsor I've pretty much gotten everything working. I have Castle Windsor implemented and working with the Controllers being served up by the WindsorControllerFactory that is part of MVCContrib. I also have Castle serving up the FluentValidation validators as is described by this article: http://www.jeremyskinner.co.uk/2010/02/22/using-fluentvalidation-with-an-ioc-container/ My problem comes in when I try to use Html.EditorForModel or EditorFor on a view. When I try to do that I get this error message: No component for supporting the service FluentValidation.IValidator`1[[System.Data.Entity.DynamicProxies.State_71C51A42554BA6C3CF05105DA05435AD209602C217FC4C34CA52ACEA2B06B99B, EntityFrameworkDynamicProxies-BrindleyInsurance.BusinessObjects, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]] was found This is due to using the POCO generation on Entity Framework 4.0. At runtime, the generated classes get wrapped with a Dynamic Proxy so tracking and lazy loading can happen. Apparently, when using EditorForModel or EditorFor, it tries to ask Windsor to create a validator for the dynamic proxy type instead of the underlying real type. Does anyone know what I can do to solve this issue?

  • How to change ErrorMessage property of the DataAnnotation validation in MVC2.0

    - by Raj Aththanayake
    My task is to change the ErrorMessage property of the DataAnnotation validation attribute in MVC2.0. For example I should be able to pass an ID instead of the actual error message for the Model property and use that ID to retrieve some content(error message) from a another service e.g database, and display that error message in the View instead of the ID. In order to do this I need to set the DataAnnotation validation attribute’s ErrorMessage property. [StringLength(2, ErrorMessage = "EmailContentID.")] [DataType(DataType.EmailAddress)] public string Email { get; set; } It seems like an easy task by just overriding the DataAnnotationsModelValidatorProvider ‘s protected override IEnumerable GetValidators(ModelMetadata metadata, ControllerContext context, IEnumerable attributes) However it seems to be a complicated enough. a. MVC DatannotationsModelValidator’s ErrorMessage property is read only. So I cannot set anything here b. System.ComponentModel.DataAnnotationErrorMessage property(get and set) which is already set in MVC DatannotationsModelValidator so we cannot set again. If you try to set you get “The property cannot set more than once…” error message appears. public class CustomDataAnnotationProvider : DataAnnotationsModelValidatorProvider { protected override IEnumerable GetValidators(ModelMetadata metadata, ControllerContext context, IEnumerable attributes) { IEnumerable validators = base.GetValidators(metadata, context, attributes); foreach (ValidationAttribute validator in validators.OfType<ValidationAttribute>()) { validator.ErrorMessage = "Error string from DB"; } //...... } Can anyone please help me on this?

  • Wordpress SQL Select Multiple Meta Values / Meta Keys / Custom Fields

    - by Wes
    I am trying to modify a wordpress / MySQL function to display a little more information. I'm currently running the following query that selects the post, joins the 'postmeta' and gets the info where the meta_key = _liked function most_liked_posts($numberOf, $before, $after, $show_count) { global $wpdb; $request = "SELECT ID, post_title, meta_value FROM $wpdb->posts, $wpdb->postmeta"; $request .= " WHERE $wpdb->posts.ID = $wpdb->postmeta.post_id"; $request .= " AND post_status='publish' AND post_type='post' AND meta_key='_liked' "; $request .= " ORDER BY $wpdb->postmeta.meta_value+0 DESC LIMIT $numberOf"; $posts = $wpdb->get_results($request); foreach ($posts as $post) { $post_title = stripslashes($post->post_title); $permalink = get_permalink($post->ID); $post_count = $post->meta_value; echo $before.'<a href="' . $permalink . '" title="' . $post_title.'" rel="nofollow">' . $post_title . '</a>'; echo $show_count == '1' ? ' ('.$post_count.')' : ''; echo $after; } } The important part being: $post_count = $post->meta_value; But now I want to also grab a value that is attached to each post called wbphoto How do I specify that $post_count = _liked and $photo = wbphoto ?

  • nHibernate Mapping with Oracle Varchar2 Data Types

    - by Blake Blackwell
    I am new to nHibernate and having some issues getting over the learning curve. My current question involves passing a string value as a parameter to a stored sproc. The error I get is: Input string is not in correct format. My mapping file looks like this: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="MyCompany.MyProject.Core" namespace="MyCompany.MyProject.Core" > <class name="MyCompany.MyProject.Core.MyTable" table="My_Table" lazy="false"> <id name="Id" column="Id"></id> <property name="Name" column="Name" /> </class> <sql-query name="sp_GetTable" callable="true"> <query-param name="int_Id" type="int"/> <query-param name="vch_MyId" type="String"/> <return class="MyCompany.MyProject.Core.MyTable" /> call procedure MYPKG.MYPROC(:int_Id,:vch_MyId) </sql-query> </hibernate-mapping> When I debug nHibernate it looks like it is not an actual string value, but instead just an object value. Not sure about that though... EDIT: Adding additional code for clarification: UNIT Test List<ProcedureParameter> parms = new List<ProcedureParameter>(); parms.Add( new ProcedureParameter { ParamName = "int_Id", ParamValue = 1} ); parms.Add( new ProcedureParameter { ParamName = "vch_MyId", ParamValue = "{D18BED07-84AB-494F-A94F-6F894E284227}" } ); try { IList<MyTable> myTables = _context.GetAllByID<MyTable>( "sp_GetTable", parms ); Assert.AreNotEqual( 0, myTables.Count ); } catch( Exception ex ) { throw ex; } Data Context Method IQuery query = _session.GetNamedQuery( queryName ); foreach( ProcedureParameter parm in parms ) { query.SetParameter(parm.ParamName, "'" + parm.ParamValue + "'"); } return query.List<T>(); Come to think of it, it may have something to do with my DataContext method.

  • Best practise to send mass email within application (ASP.NET MVC 2, C#)?

    - by gurdan
    Whats the best way to implement mass email sending feature within web app? Two major cases: Email messages for separate registered users depending on their activities (just sending short reminders to user for ex about new posts in his created topic) "Send email for all registered users" functionality, it will be nice to have feature for system administrator to send some messages for all registered users. Of course adding all emails to recipient isn't the way we can go, because email addresses for each user are anonimous. As i understand for case nr1 there is no problem just create some email message via System.Net.Mail by creating new mail message and sending it... but what about case nr 2??? i guess smth like this: foreach(var emailAddress in emailAddresses) { MailMessage mail = new MailMessage(); mail.From = new MailAddress("[email protected]"); mail.To.Add(emailAddress); mail.Subject = "test"; mail.Body = "test"; SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587); smtp.Send(mail); } isn't the good way :) so the question is what is the best way to achieve this ? btw we have no possiblity to deploy some serive for email sending, this should be integrated into web application.

  • Zend Studio Debugger returns Application Error

    - by Keyne
    When I run debug for my public/index.php I got an application error as output. I've seen that it occurs at this line: foreach($feed->findFeedEntries($entriesLimit) as $entry) If I put a breakpoint before this, all works as expected, I mean, the error is after the line above. If I remove findFeedEntries() method, I can perform debugging without erros. To clarify, this method is in my row object as described bellow: This is the error <?php class Model_DbTable_FeedEntries extends Zf_Db_Table { public function fetchNewEntries($feed_id) { $Feeds = new Model_DbTable_Feeds(); $Feed = $Feeds->getById($feed_id); // ERROR IS HERE! The colum doesn't exists! // And this is only on zend-debugger!!! var_dump($Feed->link) // ... } } I'm completely lost about what's happening, once my application has no errors, the problem is with zend-debugger. The error is: An error occurred Application error Exception information: Message: Specified column "link" is not in the row Stack trace: #0 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\FeedEntries.php(75): Zend_Db_Table_Row_Abstract->__get('link') #1 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\FeedEntries.php(50): Model_DbTable_FeedEntries->fetchNewEntries('1') #2 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\models\DbTable\Row\Feed.php(15): Model_DbTable_FeedEntries->getAllByFeedId('1', 1) #3 C:\Program Files\xampp\htdocs\desenvolvimentistas\application\modules\default\controllers\IndexController.php(41): Model_DbTable_Row_Feed->findFeedEntries(1) #4 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Action.php(513): IndexController->indexAction() #5 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Dispatcher\Standard.php(289): Zend_Controller_Action->dispatch('indexAction') #6 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Controller\Front.php(954): Zend_Controller_Dispatcher_Standard->dispatch(Object(Zend_Controller_Request_Http), Object(Zend_Controller_Response_Http)) #7 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Application\Bootstrap\Bootstrap.php(97): Zend_Controller_Front->dispatch() #8 C:\Program Files\xampp\htdocs\ZendFramework-1.10.0-minimal\library\Zend\Application.php(366): Zend_Application_Bootstrap_Bootstrap->run() #9 C:\Program Files\xampp\htdocs\desenvolvimentistas\public\index.php(54): Zend_Application->run() #10 C:\Users\RAPOSO\AppData\Local\Temp\dummy.php(1): include('C:\Program File...') #11 {main} I've notice that when I get the row object my colums names are not right.

  • Why is my WPF splash screen progress bar out of sync with the execution of the startup steps?

    - by denny_ch
    Hello, I've implemented a simple WPF splash screen window which informs the user about the progress of the application startup. The startup steps are defined this way: var bootSequence = new[] { new {Do = (Action) InitLogging, Message = "Init logging..."}, new {Do = (Action) InitNHibernate, Message = "Init NHibernate..."}, new {Do = (Action) SetupUnityContainer, Message = "Init Unity..."}, new {Do = (Action) UserLogOn, Message = "Logon..."}, new {Do = (Action) PrefetchData, Message = "Caching..."}, }; InitLogging etc. are methods defined elsewhere, which performs some time consuming tasks. The boot sequence gets executed this way: foreach (var step in bootSequence) { _status.Update(step.Message); step.Do(); } _status denotes an instance of my XAML splash screen window containing a progress bar and a label for status information. Its Update() method is defined as follows: public void Update(string status) { int value = ++_updateSteps; Update(status, value); } private void Update(string status, int value) { var dispatcherOperation = Dispatcher.BeginInvoke( DispatcherPriority.Background, (ThreadStart) delegate { lblStatus.Content = status; progressBar.Value = value; }); dispatcherOperation.Wait(); } In the main this works, the steps get executed and the splash screen shows the progress. But I observed that the splash screen for some reasons doesn't update its content for all steps. This is the reason I called the Dispatcher async and wait for its completion. But even this didn't help. Has anyone else experienced this or some similar behaviour and has some advice how to keep the splash screen's update in sync with the execution of the boot sequence steps? I know that the users will unlikely notice this behaviour, since the splash screen is doing something and the application starts after booting is completed. But myself isn't sleeping well, because I don't know why it is not working as expected... Thx for your help, Denny

  • Castle Windsor and its own configuration file

    - by Coppermill
    I am using Castle Windsor for IoC, and have the configuration held in the web.config/app.config, using the following factory: public static TYPE Factory(string component) { var windsorContainer = new WindsorContainer(new XmlInterpreter()); var service = windsorContainer.Resolve<TYPE>(component); if (service == null) throw new ArgumentNullException(string.Format("Unable to find container {0}", component)); return service; } and my web.config looking like this: <configuration> <configSections> <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor"/> </configSections> <castle> <components> <component id="Data" service="Data.IData, Data" type="Data.DataService, Data"/> </components> </castle> <appSettings>....... Which works fine, but I'd like to place the configuration for Castle Windsor in a file called castle.config. How do I do this?

  • Custom activity in WF 4.0: WorkflowItemsPresenter wont show converted array

  • Suggestions for doing async I/O with Task Parallel Library

    - by anelson
    I have some high performance file transfer code which I wrote in C# using the Async Programming Model (APM) idiom (eg, BeginRead/EndRead). This code reads a file from a local disk and writes it to a socket. For best performance on modern hardware, it's important to keep more than one outstanding I/O operation in flight whenever possible. Thus, I post several BeginRead operations on the file, then when one completes, I call a BeginSend on the socket, and when that completes I do another BeginRead on the file. The details are a bit more complicated than that but at the high level that's the idea. I've got the APM-based code working, but it's very hard to follow and probably has subtle concurrency bugs. I'd love to use TPL for this instead. I figured Task.Factory.FromAsync would just about do it, but there's a catch. All of the I/O samples I've seen (most particularly the StreamExtensions class in the Parallel Extensions Extras) assume one read followed by one write. This won't perform the way I need. I can't use something simple like Parallel.ForEach or the Extras extension Task.Factory.Iterate because the async I/O tasks don't spend much time on a worker thread, so Parallel just starts up another task, resulting in potentially dozens or hundreds of pending I/O operations; way too much! You can work around that by Waiting on your tasks, but that causes creation of an event handle (a kernel object), and a blocking wait on a task wait handle, which ties up a worker thread. My APM-based implementation avoids both of those things. I've been playing around with different ways to keep multiple read/write operations in flight, and I've managed to do so using continuations that call a method that creates another task, but it feels awkward, and definitely doesn't feel like idiomatic TPL. Has anyone else grappled with an issue like this with the TPL? Any suggestions?

  • eclipse tomcat debug mode slow - pegs cpu

    - by andersonbd1
    Running Tomcat through eclipse works fine in non-debug mode, but not in debug mode. When I try to start the Tomcat server in debug mode, the console output looks fine for a while, but then starts slowing down and eventually just stops, pegging the cpu at 100%. I don't think it's relevant, but just in case - here's the console output right about when it starts slowing down and eventually stopping (by stopping I mean no more console output, but still 100% cpu). 2009-09-02 14:35:30,859 INFO NONE org.springframework.context.weaving.DefaultContextLoadTimeWeaver:72 - Found Spring's JVM agent for instrumentation 2009-09-02 14:35:49,562 INFO NONE org.springframework.beans.factory.support.DefaultListableBeanFactory:414 - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@ed889d: defining beans [... 2009-09-02 14:37:31,031 INFO NONE org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean:221 - Building JPA container EntityManagerFactory for persistence unit ... I tried everything I could think of to fix it: cleanesd tomcat working directory restarted eclipse restarted Windows refreshed/cleaned all projects I first had this problem last week using eclipse ganymede. I had been running fine in debug-mode for several months prior to this issue. I didn't make any significant changes to our project that would cause this. Eventually, I upgraded to eclipse galileo which solved my problem. Now 2 days later, I'm having the same problem in galileo. Like I said it works fine in non-debug mode. Any help is much appreciated. I should add that other things work in debug mode - for instance junit tests, so it is something specific to tomcat.

  • Youtube API - How to limit results for pagination?

    - by worchyld
    I want to grab a user's uploads (ie: BBC) and limit the output to 10 per page. Whilst I can use the following URL: http://gdata.youtube.com/feeds/api/users/bbc/uploads/?start-index=1&max-results=10 The above works okay. I want to use the query method instead: The Zend Framework docs: http://framework.zend.com/manual/en/zend.gdata.youtube.html State that I can retrieve videos uploaded by a user, but ideally I want to use the query method to limit the results for a pagination. The query method is on the Zend framework docs (same page as before under the title 'Searching for videos by metadata') and is similar to this: [code] $yt = new Zend_Gdata_YouTube(); $query = $yt-newVideoQuery(); $query-setTime('today'); $query-setMaxResults(10); $videoFeed = $yt-getUserUploads( NULL, $query ); // Output print ''; foreach($videoFeed as $video): print '' . $video-title . ''; endforeach; print ''; [/code] The problem is I can't do $query-setUser('bbc'). I tried setAuthor but this returns a totally different result. Ideally, I want to use the query method to grab the results in a paginated fashion. How do I use the $query method to set my limits for pagination? Thanks.

  • How do I get folder size with Exchange Web Services 2010 Managed API?

    - by Adam Tuttle
    I'm attempting to use EWS 2010 Managed API to get the total size of a user's mailbox. I haven't found a web service method to get this data, so I figured I would try to calculate it. I found one seemingly-applicable question on another site about finding mailbox sizes with EWS 2007, but either I'm not understanding what it's asking me to do, or that method just doesn't work with EWS 2010. Noodling around in the code insight, I was able to write what I thought was a method that would traverse the folder structure recursively and result in a combined total for all folders inside the Inbox: private int traverseChildFoldersForSize(Folder f) { int folderSizeSum = 0; if (f.ChildFolderCount > 0) { foreach (Folder c in f.FindFolders(new FolderView(10000))) { folderSizeSum += traverseChildFoldersForSize(c); } } folderSizeSum += (int)f.ManagedFolderInformation.FolderSize; return folderSizeSum; } (Assumes there aren't more than 10,000 folders inside a given folder. Figure that's a safe bet...) Unfortunately, this doesn't work. I'm initiating the recursion with this code: Folder root = Folder.Bind(svc, WellKnownFolderName.Inbox); int totalSize = traverseChildFoldersForSize(root); But a Null Pointer Exception is thrown, essentially saying that [folder].ManagedFolderInformation is a null object reference. For clarity, I also attempted to just get the size of the root folder: Console.Write(root.ManagedFolderInformation.FolderSize.ToString()); Which threw the same NPE exception, so I know that it's not just that once you get to a certain depth in the directory tree that ManagedFolderInformation doesn't exist. Any ideas on how to get the total size of the user's mailbox? Am I barking up the wrong tree?

  • .NET converting simple arrays to List Generics

    - by Manish Sinha
    This question might seem trivial and also stupid at the first glance, but it is much more than this. I have an array of any type T (T[]) and I want to convert it into a List generic (List<T>). Is there any other way apart from creating a Generic list, traversing the whole array and adding the element in the List? Present Situation: string[] strList = {'foo','bar','meh'}; List<string> listOfStr = new List<string>(); foreach(string s in strList) { listOfStr.Add(s); } My ideal situation: string[] strList = {'foo','bar','meh'}; List<string> listOfStr = strList.ToList<string>(); Or: string[] strList = {'foo','bar','meh'}; List<string> listOfStr = new List<string>(strList); I am suggesting the last 2 method names as I think compiler or CLR can perform some optimizations on the whole operations if It want inbuilt. P.S.: I am not talking about the Array or ArrayList Type

  • Kohana 3: How to find the active item in a dynamic menu

    - by Svish
    Maybe not the best explanation, but hear me out. Say I have the following in a config file called menu.php: // Default controller is 'home' and default action is 'index' return array( 'items' => array( 'Home' => '', 'News' => 'news', 'Resources' => 'resources', ), ); I now want to print this out as a menu, which is pretty simple: foreach(Kohana::config('menu.items') as $title => $uri) { echo '<li>' . HTML::anchor($uri, $title) . '</li>'; } However, I want to find the $uri that matches the current controller and action. And if the action is the default one or not. What I want to end up with is that menu item should have id="active-item" if it is the linking to the current controller, but the default action. And id="active-subitem if it is linking to the current controller and the action is not the default one. Hope that made sense... Anyone able to help me out here? Both in how to do this in Kohana 3 and also how it should be done in Kohana 3. I'm sure there are lots of ways, but yeah... any help is welcome :) Examples: domain.com -- Home should be active-item since it is the default controller domain.com/home -- Home should be active-item domain.com/home/index -- Home should be active-item since index is the default action domain.com/resources -- Resources should be active-item domain.com/resources/get/7 -- Resources should be active-subitem since get is not the default action

  • How to Process Lambda Expressions Passed as Argument Into Method - C# .NET 3.5

    - by Sunday Ironfoot
    My knowledge of Lambda expressions is a bit shaky, while I can write code that uses Lambda expressions (aka LINQ), I'm trying to write my own method that takes a few arguments that are of type Lambda Expression. Background: I'm trying to write a method that returns a Tree Collection of objects of type TreeItem from literally ANY other object type. I have the following so far: public class TreeItem { public string Id { get; set; } public string Text { get; set; } public TreeItem Parent { get; protected set; } public IList<TreeItem> Children { get { // Implementation that returns custom TreeItemCollection type } } public static IList<TreeItem> GetTreeFromObject<T>(IList<T> items, Expression<Func<T, string>> id, Expression<Func<T, string>> text, Expression<Func<T, IList<T>>> childProperty) where T : class { foreach (T item in items) { // Errrm!?? What do I do now? } return null; } } ...which can be called via... IList<TreeItem> treeItems = TreeItem.GetTreeFromObject<Category>( categories, c => c.Id, c => c.Name, c => c.ChildCategories); I could replace the Expressions with string values, and just use reflection, but I'm trying to avoid this as I want to make it strongly typed. My reasons for doing this is that I have a control that accepts a List of type TreeItem, whereas I have dozens of different types that are all in a tree like structure, and don't want to write seperate conversion methods for each type (trying to adhere to the DRY principle). Am I going about this the right way? Is there a better way of doing this perhaps?

  • Silverlight async calls and anonymous methods....

    - by JLewis
    I know there are a couple of debates on this kind of thing.... At any rate, I have several cases where I need to populate combobox items based on enumerations returned from the WCF service. In an effort to keep code clean, I started this approach. After looking into it more, I don't think the this works as well is initially thought... I am throwing this out to get recommendations/advice/code snippets on how you would do this or how you currently do this. I may be forced to have a seperate, non anonymous method, procedure. I hate doing this for something like this but at the moment, don't see it working another way... EventHandler<GetEnumerationsForTypeCompletedEventArgs> ev = null; ev = delegate(object eventSender, GetEnumerationsForTypeCompletedEventArgs eventArgs) { if (eventArgs.Error == null) { //comboBox.ItemsSource = eventArgs.Result; // populate combox for display purposes (for now) foreach (Enumeration e in eventArgs.Result) { ComboBoxItem cbi = new ComboBoxItem(); cbi.Content = e.EnumerationValueDisplayed; comboBox.Items.Add(cbi); } // remove event so we don't keep adding new events each time we need an enumeration proxy.GetEnumerationsForTypeCompleted -= ev; } }; proxy.GetEnumerationsForTypeCompleted += ev; proxy.GetEnumerationsForTypeAsync(sEnumerationType); Basically in this example we use ev to hold the anonymous method so we can then use ev from within the method to remove it from the events once called. This prevents this method from getting called more than one time. I suspect that the comboBox local var declared before this call, but within the same method, is not always the combobox originally intended but can't really verify that yet. I may add a tag to it to do some tests and populating to verify. Sorry if this is not clear. I can elaborate more if needed. Thanks Jeff

  • Multiple Conditions in Lambda Expressions at runtime C#

    - by Ryan
    Hi, I would like to know how to be able to make an Expression tree by inputting more than one parameter Example: dataContext.Users.Where(u => u.username == "Username" && u.password == "Password") At the moment the code that I did was the following but would like to make more general in regards whether the condition is OR or AND public Func<TLinqEntity, bool> ANDOnlyParams(string[] paramNames, object[] values) { List<ParameterExpression> paramList = new List<ParameterExpression>(); foreach (string param in paramNames) { paramList.Add(Expression.Parameter(typeof(TLinqEntity), param)); } List<LambdaExpression> lexList = new List<LambdaExpression>(); for (int i = 0; i < paramNames.Length; i++) { if (i == 0) { Expression bodyInner = Expression.Equal( Expression.Property( paramList[i], paramNames[i]), Expression.Constant(values[i])); lexList.Add(Expression.Lambda(bodyInner, paramList[i])); } else { Expression bodyOuter = Expression.And( Expression.Equal( Expression.Property( paramList[i], paramNames[i]), Expression.Constant(values[i])), Expression.Invoke(lexList[i - 1], paramList[i])); lexList.Add(Expression.Lambda(bodyOuter, paramList[i])); } } return ((Expression<Func<TLinqEntity, bool>>)lexList[lexList.Count - 1]).Compile(); } Thanks

  • C# - Get values of static properties from static class

    - by JamesW
    I'm trying to loop through some static properties in a simple static class in order to populate a combo box with their values, but am having difficulties. Here is the simple class: public static MyStaticClass() { public static string property1 = "NumberOne"; public static string property2 = "NumberTwo"; public static string property3 = "NumberThree"; } ... and the code attempting to retrieve the values: Type myType = typeof(MyStaticClass); PropertyInfo[] properties = myType.GetProperties( BindingFlags.Public | BindingFlags.Static | BindingFlags.DeclaredOnly); foreach (PropertyInfo property in properties) { MyComboBox.Items.Add(property.GetValue(myType, null).ToString()); } If I don't supply any binding flags then I get about 57 properties including things like System.Reflection.Module Module and all sorts of other inherited things I don't care about. My 3 declared properties are not present. If I supply various combinations of other flags then it always returns 0 properties. Great. Does it matter that my static class is actually declared within another non-static class? Please help! What am I doing wrong?

  • Scaling gwt's "Contacts" (sample project) AppController with MVP

    - by brad
    I'm just learning GWT so I'm still trying to sort out all of its quirks and features. I'm reading through the example they give illustrating the MVP pattern, and I pretty much get it, except I'm wondering about one thing. The AppController they use implements the ValueChangeHandler interface and the onValueChange method is triggered when history changes. My problem is with this onValueChange in the AppController (i've included it below for anyone who hasn't seen the sample project). It's doing a string comparison on the history token sent in and instantiating the appropriate presenter to handle the action. This is all fine and dandy for the sample app with 3 actions, but how would one scale this to a real app with many more actions? Sticking to this pattern would lead to a pretty large/ugly else if, but I'm still too new to GWT (and java) to infer a better pattern for larger apps. Any help is greatly appreciated! public class AppController implements Presenter, ValueChangeHandler<String> { ... public void onValueChange(ValueChangeEvent<String> event) { String token = event.getValue(); if (token != null) { Presenter presenter = null; if (token.equals("list")) { presenter = new ContactsPresenter(rpcService, eventBus, new ContactsView()); } else if (token.equals("add")) { presenter = new EditContactPresenter(rpcService, eventBus, new EditContactView()); } else if (token.equals("edit")) { presenter = new EditContactPresenter(rpcService, eventBus, new EditContactView()); } if (presenter != null) { presenter.go(container); } } } }

  • How can I dynamically access user control properties?

    - by rahkim
    Im trying to create a "user control menu" where links to a page's usercontrols are placed at the top of the page. This will allow me to put several usercontrols on a page and allow the user to jump to that section of the page without scrolling so much. In order to do this, I put each usercontrol in a folder (usercontrols) and gave each control a Description property (<%@ Control Language="C#" Description = "Vehicles" .... %>). My question is how can I access this description dynamically? I want to use this description as the link in my menu. So far, I have a foreach on my page that looks in the ControlCollection for a control that is of the ASP.usercontrols type. If it is I would assume that I could access its attributes and grab that description property. How can I do this? (Im also open to a better way to achieve my "user control menu", but maybe thats another question.) Should I use ((System.Web.UI.UserControl)mydynamiccontrol).Attributes.Keys?
