  • sharp architecture question

    - by csetzkorn
    I am trying to get my head around the sharp architecture and follow the tutorial. I am using this code: using Bla.Core; using System.Collections.Generic; using Bla.Core.DataInterfaces; using System.Web.Mvc; using SharpArch.Core; using SharpArch.Web; using Bla.Web; namespace Bla.Web.Controllers { public class UsersController { public UsersController(IUserRepository userRepository) { Check.Require(userRepository != null,"userRepository may not be null"); this.userRepository = userRepository; } public ActionResult ListStaffMembersMatching(string filter) { List<User> matchingUsers = userRepository.FindAllMatching(filter); return View("ListUsersMatchingFilter", matchingUsers); } private readonly IUserRepository userRepository; } } I get this error: The name 'View' does not exist in the current context I have used all the correct using statements and referenced the assemblies as far as I can see. The views live in Bla.Web in this architecture. Can anyone see the problem? Thanks. Christian

  • IoC and dataContext disposing in asp.net mvc 2 application

    - by zerkms
    I have the Global.asax like the code below: public class MvcApplication : System.Web.HttpApplication { public static void RegisterRoutes(RouteCollection routes) { // .... } protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); ControllerBuilder.Current.SetControllerFactory(typeof(IOCControllerFactory)); } } public class IOCControllerFactory : DefaultControllerFactory { private readonly IKernel kernel; public IOCControllerFactory() { kernel = new StandardKernel(new NanocrmContainer()); } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { if (controllerType == null) return base.GetControllerInstance(requestContext, controllerType); var controller = kernel.TryGet(controllerType) as IController; if (controller == null) return base.GetControllerInstance(requestContext, controllerType); var standartController = controller as Controller; if (standartController is IIoCController) ((IIoCController)standartController).SetIoc(kernel); return standartController; } class NanocrmContainer : Ninject.Modules.NinjectModule { public override void Load() { // ... Bind<DomainModel.Entities.db>().ToSelf().InRequestScope().WithConstructorArgument("connection", "Data Source=lims;Initial Catalog=nanocrm;Persist Security Info=True;User ID=***;Password=***"); } } } In this case if somewhere it is the class, defined like: public class UserRepository : IUserRepository { private db dataContext; private IUserGroupRepository userGroupRepository; public UserRepository(db dataContext, IUserGroupRepository userGroupRepository) { this.dataContext = dataContext; this.userGroupRepository = userGroupRepository; } } then the dataContext instance is created (if no one was created in this request scope) by Ninject. So the trouble now is - where to invoke dataContext method .Dispose()?

  • StackOverFlowException - but oviously NO recursion/endless loop

    - by user567706
    Hi there, I'm now blocked by this problem the entire day, read thousands of google results, but nothing seems to reflect my problem or even come near to it... i hope any of you has a push into the right direction for me. I wrote a client-server-application (so more like 2 applications) - the client collects data about his system, as well as a screenshot, serializes all this into a XML stream (the picture as a byte[]-array]) and sends this to the server in regular intervals. The server receives the stream (via tcp), deserializes the xml to an information-object and shows the information on a windows form. This process is running stable for about 20-25 minutes at a submission interval of 3 seconds. When observing the memory usage there's nothing significant to see, also kinda stable. But after these 20-25 mins the server throws a StackOverflowException at the point where it deserializes the tcp-stream, especially when setting the Image property from the byte[]-array. I thoroughly searched for recursive or endless loops, and regarding the fact that it occurs after thousands of sucessfull intervals, i could hardly imagine that. public byte[] ImageBase { get { MemoryStream ms = new MemoryStream(); _screen.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); return ms.GetBuffer(); } set { if (_screen != null) _screen.Dispose(); //preventing well-known image memory leak MemoryStream ms = new MemoryStream(value); try { _screen = Image.FromStream(ms); //<< EXCEPTION THROWING HERE } catch (StackOverflowException ex) //thx to new CLR management this wont work anymore -.- { Console.WriteLine(ex.Message + Environment.NewLine + ex.StackTrace); } ms.Dispose(); ms = null; } } I hope that more code would be unnecessary, or it could get very complex... Please help, i have no clue at all anymore thx Chris

  • [ASP.NET] Change CulturalInfo after button click

    - by Bart
    Hello, i have multilingual asp.net site. there is masterpage and default.aspx in masterpage i put two buttons one to click when i want to change the language to english, second for polish. I want to change the language after click on these buttons (and all changes should appear automatically on the page) here is a code for both: protected void EnglishButton_Click(object sender, ImageClickEventArgs e) { string selectedLanguage = "en-US"; //Sets the cookie that is to be used by InitializeCulture() in content page HttpCookie cookie = new HttpCookie("CultureInfo"); cookie.Value = selectedLanguage; Response.Cookies.Add(cookie); Server.Transfer(Request.Path); } protected void PolishButton_Click(object sender, ImageClickEventArgs e) { string selectedLanguage = "pl-PL"; //Sets the cookie that is to be used by InitializeCulture() in content page HttpCookie cookie = new HttpCookie("CultureInfo"); cookie.Value = selectedLanguage; Response.Cookies.Add(cookie); Server.Transfer(Request.Path); } in default.aspx.cs i have InitializeCulture(): protected override void InitializeCulture() { HttpCookie cookie = Request.Cookies["CultureInfo"]; // if there is some value in cookie if (cookie != null && cookie.Value != null) { Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(cookie.Value); Thread.CurrentThread.CurrentUICulture = new CultureInfo(cookie.Value); } else // if none value has been sent by cookie, set default language { Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("pl-PL"); Thread.CurrentThread.CurrentUICulture = new CultureInfo("pl-PL"); } base.InitializeCulture(); } i added resource files and in one label i show actual culture: Welcome.Text = "Culture: " + System.Globalization.CultureInfo.CurrentCulture.ToString(); the problem is that when i run this app and click e.g. english button (default language is polish), there is no effect. if i click it second time or press F5, the changes are applies and in the label is Culture: en-US. the same happens if i want to change language back to polish (it works after second click (or one click and refresh)). What am i doing wrong? Regards, Bart

  • jQuery: script remember values between times it is triggered?

    - by Marius
    Hello there, I am writing an ajax script in jQuery. The script gets new or previous page from a php documents that returns HTML. If, located on page 1, I click next, the script IS able to find the next page number (page2), but when I click it AGAIN, the script again has to be able to find the next page number (page3) and at the minute it doesnt. I was wondering how I can save a variable between time a script is triggered, so that I can just + 1 to each time somebody clicks "next", and -1 when somebody clicks "previous". This is my code: $('.buttonNeste').click(function(event){ event.preventDefault(); if (page == null || id == null ) { var page = parseInt($(this).closest('.paginationFullWidth').attr('id')) + 1; var id = $(this).closest('.paginationFullWidth').siblings('.jtextfill').children('h1').attr('id'); } else { var page = page + 1; } var target = $(this); $.post( 'http://www.example.com/controllers/foo.php', { 'page': ( page ), 'id': id }, function(data) { $(target).closest('.paginationFullWidth').siblings('.commentsContainer').html(data); }); }); Thank you for your time. Kind regards, Marius

  • Proxy is created, and interceptor is in the __interceptors array, but the interceptor is never calle

    - by drewbu
    This is the first time I've used interceptors with the fluent registration and I'm missing something. With the following registration, I can resolve an IProcessingStep, and it's a proxy class and the interceptor is in the __interceptors array, but for some reason, the interceptor is not called. Any ideas what I'm missing? Thanks, Drew AllTypes.Of<IProcessingStep>() .FromAssembly(Assembly.GetExecutingAssembly()) .ConfigureFor<IProcessingStep>(c => c .Unless(Component.ServiceAlreadyRegistered) .LifeStyle.PerThread .Interceptors(InterceptorReference.ForType<StepLoggingInterceptor>()).First ), Component.For<StepMonitorInterceptor>(), Component.For<StepLoggingInterceptor>(), Component.For<StoreInThreadInterceptor>() public abstract class BaseStepInterceptor : IInterceptor { public void Intercept(IInvocation invocation) { IProcessingStep processingStep = (IProcessingStep)invocation.InvocationTarget; Command cmd = (Command)invocation.Arguments[0]; OnIntercept(invocation, processingStep, cmd); } protected abstract void OnIntercept(IInvocation invocation, IProcessingStep processingStep, Command cmd); } public class StepLoggingInterceptor : BaseStepInterceptor { private readonly ILogger _logger; public StepLoggingInterceptor(ILogger logger) { _logger = logger; } protected override void OnIntercept(IInvocation invocation, IProcessingStep processingStep, Command cmd) { _logger.TraceFormat("<{0}> for cmd:<{1}> - begin", processingStep.StepType, cmd.Id); bool exceptionThrown = false; try { invocation.Proceed(); } catch { exceptionThrown = true; throw; } finally { _logger.TraceFormat("<{0}> for cmd:<{1}> - end <{2}> times:<{3}>", processingStep.StepType, cmd.Id, !exceptionThrown && processingStep.CompletedSuccessfully ?

  • Java 1.4 singleton containing a mutable field

    - by Philippe
    Hi, I'm working on a legacy Java 1.4 project, and I have a factory that instantiates a csv file parser as a singleton. In my csv file parser, however, I have a HashSet that will store objects created from each line of my CSV file. All that will be used by a web application, and users will be uploading CSV files, possibly concurrently. Now my question is : what is the best way to prevent my list of objects to be modified by 2 users ? So far, I'm doing the following : final class MyParser { private File csvFile = null; private static Set myObjects = Collections.synchronizedSet(new HashSet); public synchronized void setFile(File file) { this.csvFile = file; } public void parse() FileReader fr = null; try { fr = new FileReader(csvFile); synchronized(myObjects) { myObjects.clear(); while(...) { // foreach line of my CSV, create a "MyObject" myObjects.add(new MyObject(...)); } } } catch (Exception e) { //... } } } Should I leave the lock only on the myObjects Set, or should I declare the whole parse() method as synchronized ? Also, how should I synchronize - both - the setting of the csvFile and the parsing ? I feel like my actual design is broken because threads could modify the csv file several times while a possibly long parse process is running. I hope I'm being clear enough, because myself am a bit confused on those multi-synchronization issues. Thanks ;-)

  • What sorting algorithm is this?

  • SqlBulkCopy causes Deadlock on SQL Server 2000.

    - by megatoast
    I have a customized data import executable in .NET 3.5 which the SqlBulkCopy to basically do faster inserts on large amounts of data. The app basically takes an input file, massages the data and bulk uploads it into a SQL Server 2000. It was written by a consultant who was building it with a SQL 2008 database environment. Would that env difference be causing this? SQL 2000 does have the bcp utility which is what BulkCopy is based on. So, When we ran this, it triggered a Deadlock error. Error details: Transaction (Process ID 58) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. I've tried numerous ways to try to resolve it. like temporarily setting the connection string variable MultipleActiveResultSets=true, which wasn't ideal, but it still gives a Deadlock error. I also made sure it wasn't a connection time out problem. here's the function. Any advice? /// <summary> /// Bulks the insert. /// </summary> public void BulkInsert(string destinationTableName, DataTable dataTable) { SqlBulkCopy bulkCopy; if (this.Transaction != null) { bulkCopy = new SqlBulkCopy ( this.Connection, SqlBulkCopyOptions.TableLock, this.Transaction ); } else { bulkCopy = new SqlBulkCopy ( this.Connection.ConnectionString, SqlBulkCopyOptions.TableLock | SqlBulkCopyOptions.UseInternalTransaction ); } bulkCopy.ColumnMappings.Add("FeeScheduleID", "FeeScheduleID"); bulkCopy.ColumnMappings.Add("ProcedureID", "ProcedureID"); bulkCopy.ColumnMappings.Add("AltCode", "AltCode"); bulkCopy.ColumnMappings.Add("AltDescription", "AltDescription"); bulkCopy.ColumnMappings.Add("Fee", "Fee"); bulkCopy.ColumnMappings.Add("Discount", "Discount"); bulkCopy.ColumnMappings.Add("Comment", "Comment"); bulkCopy.ColumnMappings.Add("Description", "Description"); bulkCopy.BatchSize = dataTable.Rows.Count; bulkCopy.DestinationTableName = destinationTableName; bulkCopy.WriteToServer(dataTable); bulkCopy = null; }

  • javascript class calling XMLHttpRequest internally, then handling onreadystatechange

    - by Radu M
    this thing almost works: function myClass(url) { this.source = url; this.rq = null; this.someOtherProperty = "hello"; // open connection to the ajax server this.start = function() { if (window.XMLHttpRequest) { this.rq = new XMLHttpRequest(); if (this.rq.overrideMimeType) this.rq.overrideMimeType("text/xml"); } else this.rq = new ActiveXObject("Microsoft.XMLHTTP"); try { this.rq.onreadystatechange = connectionEvent; this.rq.open("GET", this.source, true); this.rq.send(null); this.state = 1; } catch (err) { // some error handler here } } function connectionEvent() { alert("i'm here"); alert("this doesnt work: " + this.someOtherProperty); } } // myClass so it's nothing more than having the XMLHttpRequest object as a member of my class, instead of globally defined, and invoking it in the traditional way. however, inside my connectionEvent callback function, the meaning of "this" is lost, even though the function itself is scoped inside myClass. i also made sure that the object that i instantiate from myClass is kept alive long enough (declared global in the script). in all the examples of using javascript classes that i saw, "this" was still available inside the inner functions. for me, it is not, even if i take my function outside and make it a myClass.prototype.connectionEvent. what am i doing wrong? thank you.

  • .htpasswd under IIS - does it work?

    - by Cyrcle
    I'm trying to password protect a directory on a server that's running IIS. I've put the following in the .htaccess file in that directory - AuthName "Restricted Area" AuthType Basic AuthUserFile /path/.htpasswd AuthGroupFile /dev/null require valid-user I've tried a whole bunch of different paths and although it's asking for a username and password it won't take it. I've tried using the path provided by _SERVER["PATH_TRANSLATED"] but that's no help either. Is this a problem with my path, or does IIS just not support .htpasswd?

  • GridViewColumn not subscribing to PropertyChanged event in a ListView

    - by Chris Wenham
    I have a ListView with a GridView that's bound to the properties of a class that implements INotifyPropertyChanged, like this: <ListView Name="SubscriptionView" Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="2" ItemsSource="{Binding Path=Subscriptions}"> <ListView.View> <GridView> <GridViewColumn Width="24" CellTemplate="{StaticResource IncludeSubscriptionTemplate}"/> <GridViewColumn Width="150" DisplayMemberBinding="{Binding Path=Name}" Header="Subscription"/> <GridViewColumn Width="75" DisplayMemberBinding="{Binding Path=RecordsWritten}" Header="Records"/> <GridViewColumn Width="Auto" CellTemplate="{StaticResource FilenameTemplate}"/> </GridView> </ListView.View> </ListView> The class looks like this: public class Subscription : INotifyPropertyChanged { public int RecordsWritten { get { return _records; } set { _records = value; if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs("RecordsWritten")); } } private int _records; ... } So I fire up a BackgroundWorker and start writing records, updating the RecordsWritten property and expecting the value to change in the UI, but it doesn't. In fact, the value of PropertyChanged on the Subscription objects is null. This is a puzzler, because I thought WPF is supposed to subscribe to the PropertyChanged event of data objects that implement INotifyPropertyChanged. Am I doing something wrong here?

  • Can't send client certificate via SslStream

    - by Jonathan
    I am doing an SSL3 handshake using an SslStream, but, in spite of my best efforts, the SslStream never sends a client certificate on my behalf. Here is the code: SSLConnection = new System.Net.Security.SslStream(SSLInOutStream, false, new System.Net.Security.RemoteCertificateValidationCallback(AlwaysValidRemoteCertificate), new System.Net.Security.LocalCertificateSelectionCallback(ChooseLocalCertificate)); X509CertificateCollection CC = new X509CertificateCollection(); CC.Add(Org.BouncyCastle.Security.DotNetUtilities.ToX509Certificate(MyLocalCertificate)); SSLConnection.AuthenticateAsClient("test", CC, System.Security.Authentication.SslProtocols.Ssl3, false); and then I have AlwaysValidRemoteCertificate just returning true, and ChooseLocalCertificate returning the zeroth element of the array. The code probably looks a little weird because the project is a little weird, but I think that is beside the point here. The SSL handshake completes. The issue is that instead of sending a certificate message on my behalf (in the handshake process), with the ASN.1 encoded certificate (MyLocalCertificate), the SslStream sends an SSL alert number 41 (no certificate) and then carries on. I know this from packet sniffing. After the handshake is completed, the SslStream marks IsAuthenticated as true, IsMutuallyAuthenticated as false, and its LocalCertificate member is null. I feel like I'm probably missing something pretty obvious here, so any ideas would be appreciated. I am a novice with SSL, and this project is off the beaten path, so I am kind of at a loss. P.S. 1: My ChooseLocalCertificate routine is called twice during the handshake, and returns a valid (as far as I can tell), non-null certificate both times. P.S. 2: SSLInOutStream is my own class, not a NetworkStream. Like I said, though, the handshake proceeds mostly normally, so I doubt this is the culprit... but who knows?

  • Problems with native Win32api RichEdit control and its IRichEditOle interface

    - by Michael
    Hi All! As part of writing custom command (dll with class that implements Interwoven command interface) for one of Interwoven Worksite dialog boxes,I need to extract information from RichEdit textbox. The only connection to the existing dialog box is its HWND handle; Seemingly trivial task , but I got stuck : Using standard win32 api functions (like GetDlgItemText) returns empty string. After using Spy++ I noticed that the dialog box gets IRichEditOle interface and seems to encapsulate the string into OLE object. Here is what I tried to do: IRichEditOle richEditOleObj = null; IntPtr ppv = IntPtr.Zero; Guid guid = new Guid("00020D00-0000-0000-c000-000000000046"); Marshal.QueryInterface(pRichEdit, ref guid, out ppv); richEditOleObj = (IRichEditOle)Marshal.GetTypedObjectForIUnknown(ppv,typeof(IRichEditOle)); judging by GetObjectCount() method of the interface there is exactly one object in the textbox - most likely the string I need to extract. I used GetObject() method and got IOleObject interface via QueryInterface : if (richEditOleObj.GetObject(0, reObject, GetObjectOptions.REO_GETOBJ_ALL_INTERFACES) == 0) //S_OK { IntPtr oleObjPpv = IntPtr.Zero; try { IOleObject oleObject = null; Guid objGuid = new Guid("00000112-0000-0000-C000-000000000046"); Marshal.QueryInterface(reObject.poleobj, ref objGuid, out oleObjPpv); oleObject = (IOleObject)Marshal.GetTypedObjectForIUnknown(oleObjPpv, typeof(IOleObject)); To negate other possibilites I tried to QueryInteface IRichEditOle to ITextDocument but this also returned empty string; tried to send EM_STREAMOUT message and read buffer returned from callback - returned empty buffer. And on this point I got stuck. Googling didn't help much - couldn't find anything that was relevant to my issue - it seems that vast majority of examples on the net about IRichEditOle and RichEdit revolve around inserting bitmap into RichEdit control... Now since I know only basic stuff about COM and OLE , I guess I am missing something important here. I would appreciate any thoughts suggestions or remarks.

  • Syncronization Exception

    - by Kurru
    Hi I have two threads, one thread processes a queue and the other thread adds stuff into the queue. I want to put the queue processing thread to sleep when its finished processing the queue I want to have the 2nd thread tell it to wake up when it has added an item to the queue However these functions call System.Threading.SynchronizationLockException: Object synchronization method was called from an unsynchronized block of code on the Monitor.PulseAll(waiting); call, because I havent syncronized the function with the waiting object. [which I dont want to do, i want to be able to process while adding items to the queue]. How can I achieve this? Queue<object> items = new Queue<object>(); object waiting = new object(); 1st Thread public void ProcessQueue() { while (true) { if (items.Count == 0) Monitor.Wait(waiting); object real = null; lock(items) { object item = items.Dequeue(); real = item; } if(real == null) continue; .. bla bla bla } } 2nd Thread involves public void AddItem(object o) { ... bla bla bla lock(items) { items.Enqueue(o); } Monitor.PulseAll(waiting); }

  • Using StringBuilder to process csv files to save heap space

    - by portoalet
    I am reading a csv file that has about has about 50,000 lines and 1.1MiB in size (and can grow larger). In Code1, I use String to process the csv, while in Code2 I use StringBuilder (only one thread executes the code, so no concurrency issues) Using StringBuilder makes the code a little bit harder to read that using normal String class. Am I prematurely optimizing things with StringBuilder in Code2 to save a bit of heap space and memory? Code1 fr = new FileReader(file); BufferedReader reader = new BufferedReader(fr); String line = reader.readLine(); while ( line != null ) { int separator = line.indexOf(','); String symbol = line.substring(0, seperator); int begin = separator; separator = line.indexOf(',', begin+1); String price = line.substring(begin+1, seperator); // Publish this update publisher.publishQuote(symbol, price); // Read the next line of fake update data line = reader.readLine(); } Code2 fr = new FileReader(file); StringBuilder stringBuilder = new StringBuilder(reader.readLine()); while( stringBuilder.toString() != null ) { int separator = stringBuilder.toString().indexOf(','); String symbol = stringBuilder.toString().substring(0, separator); int begin = separator; separator = stringBuilder.toString().indexOf(',', begin+1); String price = stringBuilder.toString().substring(begin+1, separator); publisher.publishQuote(symbol, price); stringBuilder.replace(0, stringBuilder.length(), reader.readLine()); }
