  • Silverlight 4 Overriding the DataForm Autogenerate to insert Combo Boxes bound to Converters.

    - by kmacmahon
    I've been working towards a solution for some time and could use a little help. I know I've seen an example of this before, but tonight I cannot find anything close to what I need. I have a service that provides me all my DropDownLists, either from Cache or from the DomainService. They are presented as IEnumerable, and are requested from the a repository with GetLookup(LookupId). I have created a custom attribute that I have decorated my MetaDataClass that looks something like this: [Lookup(Lookup.Products)] public Guid ProductId I have created a custom Data Form that is set to AutoGenerateFields and I am intercepting the autogenerate fields. I am checking for my CustomAttribute and that works. Given this code in my CustomDataForm (standard comments removed for brevity), what is the next step to override the field generation and place a bound combobox in its place? public class CustomDataForm : DataForm { private Dictionary<string, DataField> fields = new Dictionary<string, DataField>(); public Dictionary<string, DataField> Fields { get { return this.fields; } } protected override void OnAutoGeneratingField(DataFormAutoGeneratingFieldEventArgs e) { PropertyInfo propertyInfo = this.CurrentItem.GetType().GetProperty(e.PropertyName); foreach (Attribute attribute in propertyInfo.GetCustomAttributes(true)) { LookupFieldAttribute lookupFieldAttribute = attribute as LookupFieldAttribute; if (lookupFieldAttribute != null) { // Create a combo box. // Bind it to my Lookup IEnumerable // Set the selected item to my Field's Value // Set the binding two way } } this.fields[e.PropertyName] = e.Field; base.OnAutoGeneratingField(e); } } Any cited working examples for SL4/VS2010 would be appreciated. Thanks

  • Box2d: Set active and inactive

    - by Rosarch
    I'm writing an XNA game in C# using the XNA port of Box2d - Box2dx. Entities like trees or zombies are represented as GameObjects. GameObjectManager adds and removes them from the game world: /// <summary> /// Does the work of removing the GameObject. /// </summary> /// <param name="controller">The GameObject to be removed.</param> private void removeGameObjectFromWorld(GameObjectController controller) { controllers.Remove(controller); worldState.Models.Remove(controller.Model); controller.Model.Body.SetActive(false); } public void addGameObjectToWorld(GameObjectController controller) { controllers.Add(controller); worldState.Models.Add(controller.Model); controller.Model.Body.SetActive(true); } controllers is a collection of GameObjectController instances. worldState.Models is a collection of GameObjectModel instances. When I remove GameObjects from Box2d this way, this method gets called: void IContactListener.EndContact(Contact contact) { GameObjectController collider1 = worldQueryUtils.gameObjectOfBody(contact.GetFixtureA().GetBody()); GameObjectController collider2 = worldQueryUtils.gameObjectOfBody(contact.GetFixtureB().GetBody()); collisionRecorder.removeCollision(collider1, collider2); } worldQueryUtils: // this could be cached if we know bodies never change public GameObjectController gameObjectOfBody(Body body) { return worldQueryEngine.GameObjectsForPredicate(x => x.Model.Body == body).Single(); } This method throws an error: System.InvalidOperationException was unhandled Message="Sequence contains no elements" Source="System.Core" StackTrace: at System.Linq.Enumerable.Single[TSource](IEnumerable`1 source) at etc Why is this happening? What can I do to avoid it? This method has been called many times before the body.SetActive() was called. I feel that this may be messing it up.

  • JavaScriptSerializer().Serialize(Entity Framework object)

    - by loviji
    May be, it is not so problematic for you. but i'm trying first time with json serialization. and also read other articles in stackowerflow. I have created Entity Framework data model. then by method get all data from object: private uqsEntities _db = new uqsEntities(); //get all data from table sysMainTableColumns where tableName=paramtableName public List<sysMainTableColumns> getDataAboutMainTable(string tableName) { return (from column in _db.sysMainTableColumns where column.TableName==tableName select column).ToList(); } my webservice: public string getDataAboutMainTable() { penta.DAC.Tables dictTable = new penta.DAC.Tables(); var result = dictTable.getDataAboutMainTable("1"); return new JavaScriptSerializer().Serialize(result); } and jQuery ajax method $('#loadData').click(function() { $.ajax({ type: "POST", url: "WS/ConstructorWS.asmx/getDataAboutMainTable", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { $("#jsonResponse").html(msg); var data = eval("(" + msg + ")"); //do something with data }, error: function(msg) { } }); }); problem with data, code fails there. and i think i'm not use JavaScriptSerializer().Serialize() method very well. Please, tell me, what a big mistake I made in C# code?

  • WCF Publish/Subscribe and using callbacks to send data to specific users

    - by manemawanna
    Hello thanks for looking, I'm working on a project at the moment and have become a little stuck. I'm creating a client server app, which allows a client to subscribe to the server to have messages forwarded to it. The issue I'm having is that when the client subscribes I wish for them to only recieve updates that relate to them. The system basically passes messages from a SQL server DB which the server monitors. When a new message is recieved the server should only forward the message to the clients that it applys to, based on whos logged on the client machine. I've had a look and found code samples which sign up for messages to be broadcast across all clients who have subscribed, but not any that show how to identify individual clients and if messages apply to them. If anyone could help or point me in the right direction it would be appreciated. You can now find some of my code below: namespace AnnouncementServiceLibrary { [ServiceContract(CallbackContract = typeof(IMessageCallback))] public interface IMessageCheck { [OperationContract] void MessageCheck(); } } namespace AnnouncementServiceLibrary { public interface IMessageCallback { [OperationContract(IsOneWay = true)] void OnNewMessage(Mess message); } } public bool Subscribe() { try { IMessageCallback callback = OperationContext.Current.GetCallbackChannel<IMessageCallback>(); //If they dont already exist in the subscribers list, adds them to it if (!subscribers.Contains(callback)) subscribers.Add(callback); return true; } catch { //Otherwise if an error occurs returns false return false; } } Subscribe/Unsubscribe: private static readonly List<IMessageCallback> subscribers = new List<IMessageCallback>(); /// <summary> /// Unsubscribes the user from recieving new messages when they become avaliable /// </summary> /// <returns>Returns a bool that indicates whether the operation worked or not</returns> public bool Unsubscribe() { try { IMessageCallback callback = OperationContext.Current.GetCallbackChannel<IMessageCallback>(); //If they exist in the list of subscribers they are then removed if (subscribers.Contains(callback)) subscribers.Remove(callback); return true; } catch { //Otherwise if an error occurs returns false return false; } } Finally this at the moment isnt't working as basically when a user subscribes as it loops through I want it to filter based on the users userID: #region IMessageCheck Members /// <summary> /// This method checks for new messages recieved based on those who have subscribed for the service /// </summary> public void MessageCheck() { //A continuous loop to keep the method going while(true) { //Changes the thread to a sleep state for 2 mins? Thread.Sleep(200000); //Go through each subscriber based on there callback information subscribers.ForEach(delegate(IMessageCallback callback) { //Checks if the person who wanted the callback can still be communicated with if (((ICommunicationObject)callback).State == CommunicationState.Opened) { //Creates a link to the database and gets the required information List<Mess> mess = new List<Mess>(); List<Message> me; List<MessageLink> messLink; AnnouncementDBDataContext aDb = new AnnouncementDBDataContext(); me = aDb.Messages.ToList(); messLink = aDb.MessageLinks.ToList(); //Query to retrieve any messages which are newer than the time when the last cycle finished var result = (from a in messLink join b in me on a.UniqueID equals b.UniqueID where b.TimeRecieved > _time select new { b.UniqueID, b.Author, b.Title, b.Body, b.Priority, a.Read, b.TimeRecieved }); //Foreach result a new message is created and returned to the PC that subscribed foreach (var a in result) { Mess message = new Mess(a.UniqueID, a.Author, a.Title, a.Body, a.Priority, (bool)a.Read, a.TimeRecieved); callback.OnNewMessage(message); } } //If the requesting PC can't be contacted they are removed from the subscribers list else { subscribers.Remove(callback); } }); //Sets the datetime so the next cycle can measure against to see if new messages have been recieved _time = DateTime.Now; } } #endregion

  • Hibernate + PostgreSQL : relation does not exist - SQL Error: 0, SQLState: 42P01

    - by tommy599
    Hello, I am having some problems trying to work with PostgreSQL and Hibernate, more specifically, the issue mentioned in the title.

Everything is lowercase, so I don't think that it's that issue. If I switch to MySQL, the same code same project (I only change driver,URL, authentication), it works. In Eclipse Datasource Explorer, I can ping the DB and it succeeds. Weird thing is that I can't see the tables from there either. It expands the public schema but it doesn't expand the tables. Could it be some permission issue? Thanks!

  • C# WCF - Failed to invoke the service.

    - by Keith Barrows
    I am getting the following error when trying to use the WCF Test Client to hit my new web service. What is weird is every once in awhile it will execute once then start popping this error. Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.

  • Can I set a <probing> privatePath in ~/subdir/web.config without access to the root application .con

    - by Bago
    In ASP.NET, is it possible to set a path from a web.config in a subdir that is not setup as a virtual directory? In other words, can I reference a private assembly in the ~/subdir/bin folder? Take a look at my setup below, and let me know if I'm doing something wrong, please. Let me explain why I'm doing this: my page is setup in ~/subdir. I don't have write access to the root. I only have FTP access to the server (i.e., I am not an IIS admin and I can't login to the machine) I am trying to use FCKeditor in my subdir application Here is my folder structure: / | -subdir | | - Bin | | | *FredCK.FCKeditorV2.dll | | *Default.aspx | | *web.config Here is the <runtime> section of ~/subdir/web.config: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="subdir;subdir/bin" /> </dependentAssembly> </assemblyBinding> </runtime> I've tried all sorts of things to get to work. However, upon checking the Fusion logs, my subdir never shows up in the probing paths.

  • Update text in StatusBar in wpf using C#

    - by Archie
    hello, I have a TextBox in StatusBar in wpf which i want to update. I have a list of files in ListBox. On each file I would be doing some operation by calling say method ProcessFile(). So whenever the file processing is completed I want to show that file's name in the StatusBar text. I have tried something like this: private void button_Click(object sender, RoutedEventArgs e) { statusBar.Visibility = Visibility.Visible; DispatcherFrame frame = new DispatcherFrame(); Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Background, new DispatcherOperationCallback(TimeConsumingMethod), frame); Dispatcher.PushFrame(frame); statusBar.Visibility = Visibility.Collapsed; } public object TimeConsumingMethod(Object arg) { ((DispatcherFrame)arg).Continue = false; foreach (string fileName in destinationFilesList.Items) { txtStatus.Text = fileName.ToString(); //Assume that each process takes some time to complete System.Threading.Thread.Sleep(1000); } return null; } But i can only see the last file's name in the StatusBar. Whats wrong with the code? Can somebody correct it? Thanks.

  • Html.DropDownListFor<> and complex object in ASP.NET MVC2

    - by dagda1
    Hi, I am looking at ASP.NET MVC2 and trying to post a complex object using the new EditorFor syntax. I have a FraudDto object that has a FraudCategory child object and I want to set this object from the values that are posted from the form. Posting a simple object is not a problem but I am struggling with how to handle complex objects with child objects. I have the following parent FraudDto object whcih I am binding to on the form: public class FraudDto { public FraudCategoryDto FraudCategory { get; set; } public List<FraudCategoryDto> FraudCategories { get; private set; } public IEnumerable<SelectListItem> FraudCategoryList { get { return FraudCategories.Select(t => new SelectListItem { Text = t.Name, Value = t.Id.ToString() }); } The child FraudCategoryDto object looks like this: public class FraudCategoryDto { public int Id { get; set; } public string Name { get; set; } } On the form, I have the following code where I want to bind the FraudCategoryDto to the dropdown. The view is of type ViewPage: <td class="tac"> <strong>Category:</strong> </td> <td> <%= Html.DropDownListFor(x => x.FraudCategory, Model.FraudTypeList)%> </td> I then have the following controller code: [HttpPost] public virtual ViewResult SaveOrUpdate(FraudDto fraudDto) { return View(fraudDto); } When the form is posted to the server, the FraudCategory property of the Fraud object is null. Are there any additional steps I need to hook up this complex object? Cheers Paul

  • Named query not known error trying to call a stored proc using Fluent NHibernate

    - by Hamman359
    I'm working on setting up NHibernate for a project and I have a few queries that, due to their complexity, we will be leaving as stored procedures. I'd like to be able to use NHibernate to call the sprocs, but have run into an error I can't figure out. Since I'm using Fluent NHibernate I'm using mixed mode mapping as recommended here. However, when I run the app I get a "Named query not known: AccountsGetSingle" exception and I can't figure out why. I think I might have a problem with my HBM mapping since I'm not very familiar with using them but I'm not sure. My NHibernate configuration code is: private ISessionFactory CreateSessionFactory() { return Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005 .ConnectionString((conn => conn.FromConnectionStringWithKey("CIDB"))) .ShowSql()) .Mappings(m => { m.HbmMappings.AddFromAssemblyOf<Account>(); m.FluentMappings.AddFromAssemblyOf<Account>(); }) .BuildSessionFactory(); } My hbm.xml file is: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <sql-query name="AccountsGetSingle"> <return alias="Account" class="Core, Account"></return> exec AccountsGetSingle </sql-query> </hibernate-mapping> And the code where I am calling the sproc looks like this: public Account Get() { return _conversation.Session .GetNamedQuery("AccountsGetSingle") .UniqueResult<Account>(); } Any thoughts or ideas would be appreciated. Thanks.

  • Why were namespaces removed from ECMAScript consideration?

    - by Bob
    Namespaces were once a consideration for ECMAScript (the old ECMAScript 4) but were taken out. As Brendan Eich says in this message: One of the use-cases for namespaces in ES4 was early binding (use namespace intrinsic), both for performance and for programmer comprehension -- no chance of runtime name binding disagreeing with any earlier binding. But early binding in any dynamic code loading scenario like the web requires a prioritization or reservation mechanism to avoid early versus late binding conflicts. Plus, as some JS implementors have noted with concern, multiple open namespaces impose runtime cost unless an implementation works significantly harder. For these reasons, namespaces and early binding (like packages before them, this past April) must go. But I'm not sure I understand all of that. What exactly is a prioritization or reservation mechanism and why would either of those be needed? Also, must early binding and namespaces go hand-in-hand? For some reason I can't wrap my head around the issues involved. Can anyone attempt a more fleshed out explanation? Also, why would namespaces impose runtime costs? In my mind I can't help but see little difference in concept between a namespace and a function using closures. For instance, Yahoo and Google both have YAHOO and google objects that "act like" namespaces in that they contain all of their public and private variables, functions, and objects within a single access point. So why, then, would a namespace be so significantly different in implementation? Maybe I just have a misconception as to what a namespace is exactly.

  • WPF derived ComboBox SelectedValuePath issue

    - by opedog
    In our application we have a very large set of data that acts as our data dictionary for ComboBox lists, etc. This data is staticly cached and keyed off of 2 variables, so I thought it wise to write a control that derived from ComboBox and exposed the 2 keys as DPs. When those 2 keys have proper values I set the ItemsSource of the ComboBox automatically from the data dictionary list it corresponds to. I also automatically set the SelectedValuePath and DisplayMemberPath to Code and Description, respectively. Here's how an example of how an item in the ItemsSource from the data dictionary list always looks: public class DataDictionaryItem { public string Code { get; set; } public string Description { get; set; } public string Code3 { get { return this.Get.Substring(0, 3); } } } The value of Code is always 4 bytes long, but sometimes I only need to bind 3 bytes of it. Hence, the Code3 property. Here's how the code looks inside my custom combobox to set the ItemsSource: private static void SetItemsSource(CustomComboBox combo) { if (string.IsNullOrEmpty(combo.Key1) || string.IsNullOrEmpty(combo.Key2)) { combo.ItemsSource = null; return; } List<DataDictionaryItem> list = GetDataDictionaryList(combo.Key1, combo.Key2); combo.ItemsSource = list; } Now, my problem is, when I change the SelectedValuePath in the XAML to Code3, it doesn't work. What I bind to SelectedValue still gets the full 4 character Code from DataDictionaryItem. I even tried rerunning SetItemsSource when the SelectedValuePath was changed and no dice. Can anyone see what I need to do to get my custom combobox to wake up and use the SelectedValuePath provided if it's overridden in the XAML? Tweaking the value in the property setter in my SelectedValue bound business object is not an option.

  • AWS Amazon EC2 - password-less SSH login for non-root users using PEM keypairs

    - by Mark White
    We've got a couple of clusters running on AWS (HAProxy/Solr, PGPool/PostgreSQL) and we've setup scripts to allow new slave instances to be auto-included into the clusters by updating their IPs to config files held on S3, then SSHing to the master instance to kick them to download the revised config and restart the service. It's all working nicely, but in testing we're using our master pem for SSH which means it needs to be stored on an instance. Not good. I want a non-root user that can use an AWS keypair who will have sudo access to run the download-config-and-restart scripts, but nothing else. rbash seems to be the way to go, but I understand this can be insecure unless setup correctly. So what security holes are there in this approach: New AWS keypair created for user.pem (not really called 'user') New user on instances: user Public key for user is in ~user/.ssh/authorized_keys (taken by creating new instance with user.pem, and copying it from /root/.ssh/authorized_keys) Private key for user is in ~user/.ssh/user.pem 'user' has login shell of /home/user/bin/rbash ~user/bin/ contains symbolic links to /bin/rbash and /usr/bin/sudo /etc/sudoers has entry "user ALL=(root) NOPASSWD: ~user/.bashrc sets PATH to /home/user/bin/ only ~user/.inputrc has 'set disable-completion on' to prevent double tabbing from 'sudo /' to find paths. ~user/ -R is owned by root with read-only access to user, except for ~user/.ssh which has write access for user (for writing known_hosts), and ~user/bin/* which are +x Inter-instance communication uses 'ssh -o StrictHostKeyChecking=no -i ~user/.ssh/user.pem user@ sudo ' Any thoughts would be welcome.

  • NHibernate SubclassMap gives DuplicateMappingException

    - by stiank81
    I'm using NHibernate to handle my database - with Fluent configuration. I'm not using Automappings. All mappings are written explicitly, and everything is working just fine. Now I wanted to add my first mapping to a subclass, using the SubclassMap, and I run into problems. With the simplest possible setup an Nhibernate DuplicateMappingException is thrown, saying that the subclass is mapped more than once: NHibernate.MappingException : Could not compile the mapping document: (XmlDocument) ---- NHibernate.DuplicateMappingException : Duplicate class/entity mapping MyNamespace.SubPerson I get this with my simple classes written for testing: public class Person { public int Id { get; set; } public string Name { get; set; } } public class SubPerson : Person { public string Foo { get; set; } } With the following mappings: public class PersonMapping : ClassMap<Person> { public PersonMapping() { Not.LazyLoad(); Id(c => c.Id); Map(c => c.Name); } } public class SubPersonMapping : SubclassMap<SubPerson> { public SubPersonMapping() { Not.LazyLoad(); Map(m => m.Foo); } } Any idea why this is happening? If there were automappings involved I guess it might have been caused by the automappings adding a mapping too, but there should be no automapping. I create my database specifying a fluent mapping: private static ISession CreateSession() { var cfg = Fluently.Configure(). Database(SQLiteConfiguration.Standard.ShowSql().UsingFile("unit_test.db")). Mappings(m => m.FluentMappings.AddFromAssemblyOf<SomeClassInTheAssemblyContainingAllMappings>()); var sessionSource = new SessionSource(cfg.BuildConfiguration().Properties, new TestModel()); var session = sessionSource.CreateSession(); _sessionSource.BuildSchema(session); return session; } Again; note that this only happens with SubclassMap. ClassMap's are working just fine!

  • How to implement EntityDataSource Where IN entity sql clause

    - by TonyS
    I want to pass a number of values into a parameter of the EntityDataSource, e.g.: Where="it.ORDER_ID IN {@OrderIdList}" (this is a property on the EntityDataSource) <WhereParameters> <asp:ControlParameter Name="OrderIdList" Type="Int16" ControlID="OrderFilterControl" PropertyName="OrderIdList" /> </WhereParameters> This doesn't work as ORDER_ID is of type int32 and I need to pass in multiple values, e.g. {1,2,3} etc The next thing I tried was setting the Where clause in code-behind and this all works except I can't get data binding on DropDownLists to work. By this I mean no value is returned from the bound dropdownlists in the EntityDataSource Updating Event. My ideal solution would be to use a WhereParameter on the EntityDataSource but any help is appreciated. Thanks, Tony.

  • Is Appcelerator Titanium now banned on the iPhone?

    - by altuzar
    This question has been answered quite clearly for MonoTouch here: http://stackoverflow.com/questions/2604033/is-monotouch-now-banned-on-the-iphone But what about Appcelerator Titanium? The new TOS from Apple and their iPhone 4 OS: 3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited). Titanium uses JavaScript but is not executed be the iPhone OS WebKit engine directly. In their Developer blog, Jeff Haynie says Titanium is on the clear, but I don't know if they are in denial. It’s our belief that we are fully in compliance with iPhone OS 4.0 ToS as we interpret them. I haven't found any official word by Apple, only opinions. And I'm quite confussed. I'm not writing another line of code for my App until... you know.

  • ASP.Net MVC2 (RTM) breaks response filtering - "Filtering is not allowed"

    - by womp
    I've just done a test run of upgrading a project to ASP.Net MVC 2 (RTM) in anticipation of the full official .Net 4.0 release coming later this month. Our application is using a minimizer for our CSS and javascript. To do so, it is making use of the HttpResponse.Filter property to set a custom filter. With the upgrade, the setter for this property is throwing an HttpException saying "Filtering is not allowed." Looking that the HttpResponse.Filter property in reflector shows this: set { if (!this.UsingHttpWriter) { throw new HttpException(SR.GetString("Filtering_not_allowed")); } ... private bool UsingHttpWriter { get { return ((this._httpWriter != null) && (this._writer == this._httpWriter)); } } Clearly something has changed in the way the HttpResponse is writing to the output stream in MVC2. Does anyone know what the change is, or at least a workaround for this? EDIT: This seems pretty radical. Some further investigation shows that ASP.Net MVC 2 RTM is using a System.Web.Mvc.ViewPage.SwitchWriter as the Output property of an HttpResponse, whereas MVC 1 was using a plain old HttpWriter. That explains why the exception is being thrown. But that doesn't explain why they've chosen to completely break this functionality. This thread seems to indicate that this is just temporary... but this makes me pretty nervous... this is the RTM after all. Any further comments appreciated on this.

    I don't know if this is ASP.NET 4.0 specific but I don't recall having this problem in previous versions. I have very simple user control called "TestModal" that contains a PlaceHolder control which I use to instantiate a template in. When I put an UpdatePanel inside this UserControl on the page the updatepanel only does full postbacks and not partial postbacks. What gives? USER CONTROL MARKUP: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TestModal.ascx.cs" Inherits="MyProject.UserControls.TestModal" %> <div id="<%= this.ClientID %>"> <asp:PlaceHolder ID="plchContentTemplate" runat="server"></asp:PlaceHolder> </div> USER CONTROL CODE BEHIND: public partial class TestModal : System.Web.UI.UserControl { private ITemplate _contentTemplate; [TemplateInstance(TemplateInstance.Single)] [PersistenceMode(PersistenceMode.InnerProperty), TemplateContainer(typeof(TemplateControl))] public ITemplate ContentTemplate { get { return _contentTemplate; } set { _contentTemplate = value; } } protected override void OnInit(EventArgs e) { base.OnInit(e); if (_contentTemplate != null) _contentTemplate.InstantiateIn(plchContentTemplate); } } ASPX PAGE MARKUP: <ajaxToolkit:ToolkitScriptManager ID="scriptManager" EnablePartialRendering="true" AllowCustomErrorsRedirect="true" CombineScripts="true" EnablePageMethods="true" ScriptMode="Release" AsyncPostBackTimeout="180" runat="server"></ajaxToolkit:ToolkitScriptManager> <uc1:TestModal ID="testModal" ClientIDMode="Static" runat="server"> <ContentTemplate> <asp:UpdatePanel ID="upAttachments" UpdateMode="Conditional" ChildrenAsTriggers="true" runat="server"> <ContentTemplate> <asp:LinkButton ID="lnkRemoveAttachment" runat="server"><img src="/images/icons/trashcan.png" style="border: none;" /></asp:LinkButton> </ContentTemplate> </asp:UpdatePanel> </ContentTemplate> </uc1:TestModal>

  • How to use Application Verifier to find memory leaks

    - by Patrick
    I want to find memory leaks in my application using standard utilities. Previously I used my own memory allocator, but other people (yes, you Neil) suggested to use Microsoft's Application Verifier, but I can't seem to get it to report my leaks. I have the following simple application: #include <iostream> #include <conio.h> class X { public: X::X() : m_value(123) {} private: int m_value; }; void main() { X *p1 = 0; X *p2 = 0; X *p3 = 0; p1 = new X(); p2 = new X(); p3 = new X(); delete p1; delete p3; } This test clearly contains a memory leak: p2 is new'd but not deleted. I build the executable using the following command lines: cl /c /EHsc /Zi /Od /MDd test.cpp link /debug test.obj I downloaded Application Verifier (4.0.0665) and enabled all checks. If I now run my test application I can see a log of it in Application Verifier, but I don't see the memory leak. Questions: Why doesn't Application Verifier report a leak? Or isn't Application Verifier really intended to find leaks? If it isn't which other tools are available to clearly report leaks at the end of the application (i.e. not by taking regular snapshots and comparing them since this is not possible in an application taking 1GB or more), including the call stack of the place of allocation (so not the simple leak reporting at the end of the CRT) If I don't find a decent utility, I still have to rely on my own memory manager (which does it perfectly).

  • C#: Struct Constructor: "fields must be fully assigned before control is returned to the caller."

    - by Rosarch
    Here is a struct I am trying to write: public struct AttackTraits { public AttackTraits(double probability, int damage, float distance) { Probability = probability; Distance = distance; Damage = damage; } private double probability; public double Probability { get { return probability; } set { if (value > 1 || value < 0) { throw new ArgumentOutOfRangeException("Probability values must be in the range [0, 1]"); } probability = value; } } public int Damage { get; set; } public float Distance { get; set; } } This results in the following compilation errors: The 'this' object cannot be used before all of its fields are assigned to Field 'AttackTraits.probability' must be fully assigned before control is returned to the caller Backing field for automatically implemented property 'AttackTraits.Damage' must be fully assigned before control is returned to the caller. Consider calling the default constructor from a constructor initializer. Backing field for automatically implemented property 'AttackTraits.Distance' must be fully assigned before control is returned to the caller. Consider calling the default constructor from a constructor initializer. What am I doing wrong?
