  • jquery ui 1.7 autocomplete show dialog on select

    - by Daniel S
    Hello, I am using an autocomplete widget, and would like a dialog to show when an item is selected. The dialog does show up, but I want a field in the dialog to receive focus when it opens. Here is what I have tried so far: //HTML <form action="#"> <p><input id="busca" /></p> </form> <div id="agregar" title="Agregar Parte"> <label for="cantidad">Cantidad:</label> <input name="cantidad" id="cantidad" size="3" /> </div> //jquery $(function(){ $("#agregar").dialog({ autoOpen: false, //also tried open: function(){$("#cantidad").focus()} } ); //.bind("dialogfocus", ... ) does not work either $("#agregar").bind("focus", function(){ $("#cantidad").focus(); }); $("#busca").autocomplete({ source: "/carrito/autocomplete/", minLength: 1, select: function(e, ui) { $("#agregar").dialog("open"); } }); }); I think autoselect's default behavior is still doing something as the autoselect widget receives focus after the dialog is shown. Any help would be greatly appreciated.

  • WPF Designer has bug with parsing generic control with overrided property

    - by Ivan Laktyunkin
    I've created a generic lookless control with virtual property: public abstract class TestControlBase<TValue> : Control { public static readonly DependencyProperty ValueProperty; static TestControlBase() { ValueProperty = DependencyProperty.Register("Value", typeof(TValue), typeof(TestControlBase<TValue>)); } protected TestControlBase() { Focusable = false; Value = default(TValue); } public virtual TValue Value { get { return (TValue)GetValue(ValueProperty); } set { SetValue(ValueProperty, value); } } } Then I've made a control derived from it and overrided Value property: public class TestControl : TestControlBase<int> { public override int Value { get { return base.Value; } set { base.Value = value; } } } So I use it in a Window XAML: <TestControls:TestControl /> When I open window in designer all is OK, but when I put mouse cursor to this line, or to this control in designer I receive exception: Exception has been thrown by the target of an invocation. at System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.RuntimeMethodHandle.InvokeMethodFast(Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) at System.Delegate.DynamicInvokeImpl(Object[] args) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) Ambiguous match found. at System.RuntimeType.GetPropertyImpl(String name, BindingFlags bindingAttr, Binder binder, Type returnType, Type[] types, ParameterModifier[] modifiers) at System.Type.GetProperty(String name) at MS.Internal.ComponentModel.DependencyPropertyKind.get_IsDirect() at MS.Internal.ComponentModel.DependencyPropertyKind.get_IsAttached() at MS.Internal.ComponentModel.APCustomTypeDescriptor.GetProperties(Attribute[] attributes) at MS.Internal.ComponentModel.APCustomTypeDescriptor.GetProperties() at System.ComponentModel.TypeDescriptor.TypeDescriptionNode.DefaultExtendedTypeDescriptor.System.ComponentModel.ICustomTypeDescriptor.GetProperties() at System.ComponentModel.TypeDescriptor.GetPropertiesImpl(Object component, Attribute[] attributes, Boolean noCustomTypeDesc, Boolean noAttributes) at System.ComponentModel.TypeDescriptor.GetProperties(Object component) at MS.Internal.Model.ModelPropertyCollectionImpl.GetProperties(String propertyNameHint) at MS.Internal.Model.ModelPropertyCollectionImpl.<GetEnumerator>d__0.MoveNext() at MS.Internal.Designer.PropertyEditing.Model.ModelPropertyMerger.<GetFirstProperties>d__0.MoveNext() at MS.Internal.Designer.PropertyEditing.PropertyInspector.UpdateCategories(Selection selection) at MS.Internal.Designer.PropertyEditing.PropertyInspector.OnSelectionChangedIdle() Who know this problem? Please explain :) I have no ideas except that WPF Designer doesn't like generics. If I replace generics by Object all is OK.

  • How to limit traffic using multicast over localhost

    - by Shane Holloway
    I'm using multicast UDP over localhost to implement a loose collection of cooperative programs running on a single machine. The following code works well on Mac OSX, Windows and linux. The flaw is that the code will receive UDP packets outside of the localhost network as well. For example, sendSock.sendto(pkt, ('192.168.0.25', 1600)) is received by my test machine when sent from another box on my network. import platform, time, socket, select addr = ("239.255.2.9", 1600) sendSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP) sendSock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, 24) sendSock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_IF, socket.inet_aton("127.0.0.1")) recvSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP) recvSock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, True) if hasattr(socket, 'SO_REUSEPORT'): recvSock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, True) recvSock.bind(("0.0.0.0", addr[1])) status = recvSock.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, socket.inet_aton(addr[0]) + socket.inet_aton("127.0.0.1")); while 1: pkt = "Hello host: {1} time: {0}".format(time.ctime(), platform.node()) print "SEND to: {0} data: {1}".format(addr, pkt) r = sendSock.sendto(pkt, addr) while select.select([recvSock], [], [], 0)[0]: data, fromAddr = recvSock.recvfrom(1024) print "RECV from: {0} data: {1}".format(fromAddr, data) time.sleep(2) I've attempted to recvSock.bind(("127.0.0.1", addr[1])), but that prevents the socket from receiving any multicast traffic. Is there a proper way to configure recvSock to only accept multicast packets from the 127/24 network, or do I need to test the address of each received packet?

  • Django | Python creating a JSON response

    - by MMRUser
    Hi, I'm trying to convert a server side AJAX response script in to an Django HttpResponse, but apparently it's not working. This is the server-side script /* RECEIVE VALUE */ $validateValue=$_POST['validateValue']; $validateId=$_POST['validateId']; $validateError=$_POST['validateError']; /* RETURN VALUE */ $arrayToJs = array(); $arrayToJs[0] = $validateId; $arrayToJs[1] = $validateError; if($validateValue =="Testuser"){ // validate?? $arrayToJs[2] = "true"; // RETURN TRUE echo '{"jsonValidateReturn":'.json_encode($arrayToJs).'}'; // RETURN ARRAY WITH success }else{ for($x=0;$x<1000000;$x++){ if($x == 990000){ $arrayToJs[2] = "false"; echo '{"jsonValidateReturn":'.json_encode($arrayToJs).'}'; // RETURN ARRAY WITH ERROR } } } And this is the converted code def validate_user(request): if request.method == 'POST': vld_value = request.POST.get('validateValue') vld_id = request.POST.get('validateId') vld_error = request.POST.get('validateError') array_to_js = [vld_id, vld_error, False] if vld_value == "TestUser": array_to_js[2] = True x = simplejson.dumps(array_to_js) return HttpResponse(x) else: array_to_js[2] = False x = simplejson.dumps(array_to_js) test = 'Error' return render_to_response('index.html',{'error':error},context_instance=RequestContext(request)) return render_to_response('index.html',context_instance=RequestContext(request)) I'm using simplejson to encode the Python list (so it will return a json array).Coudn't figure out the problem yet.But I think that I did something wrong about the 'echo'. Anyway I'm expecting an good answer it will help me a lot. Thanks.

  • JQuery Validation Plugin: Prevent validation issue on nested form

    - by Majid
    I have a form on which I use validation. This form has a section for photo upload. Initially this section contains six elements with the following code: <img class="photo_upload" src="image/app/photo_upload.jpg"> I have bound a function to the click event for the class of photo_upload. This function replaces the image with a minimal form with this code: Copy code <form onsubmit="startUploadImage();" target="control_target" enctype="multipart/form-data" method="post" action="index.php"> <input type="hidden" value="add_image" name="service"> <input type="hidden" value="1000000" name="MAX_FILE_SIZE"> <input type="file" size="10" name="photo" id="photo_file_upload"><br> <button onclick="javascript:cancel_photo_upload();return false;">Cancel</button> </form> So, essentially, after the image is clicked, I'd have a new form nested in my original, validated form. Now, when I use this new form and upload an image, I receive an error (repeated three times) saying: validator is undefined http://host.com/path/index.php Line 286 What is going on here? My guess is this Submit event bubbles up to the outer form As we have validation on that form, validation is triggered, Validation tries to find the form triggering it, Since we have not bound validation to the inner form it returns 'undefined' Now, is my assessment correct? Whether it is or not, how can I solve this issue?

  • Space in Directory Parameter of svcutil.exe

    - by Drew Frisk
    I'm attempting to download metadata for a WCF service using svcutil but I'm running into issues with the /directory:< parameter. The directory I want to save to has a space in it: C:\Service References\Logging so when I execute /t:metadata I receive the following error: Error: The directory 'C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\References\Logging' could not be found. Verify that the directory exists and that you have the appropriate permissions to read it. It looks to me like the space in "Service References" is causing the issue. From my understanding of command shell (which is very little) spaces act as delimiters for an executable. So I tried escaping the space with a carrot Service^ References and surrounding the path in double quotes "C:\Service References\Logging" but neither of those seem to be working, as the /directory: parameter doesn't recognize them as valid characters in the value. I haven't been able to find any direction in regards to this and svcutil, so I'm at a loss right now. I could download the files to a temp folder and then move them, but I would prefer not to take that approach. I would appreciate any direction that could be given on trying to resolve this. Thanks in advance.

  • Suggestions on how build an HTML Diff tool?

    - by Danimal
    In this post I asked if there were any tools that compare the structure (not actual content) of 2 HTML pages. I ask because I receive HTML templates from our designers, and frequently miss minor formatting changes in my implementation. I then waste a few hours of designer time sifting through my pages to find my mistakes. The thread offered some good suggestions, but there was nothing that fit the bill. "Fine, then", thought I, "I'll just crank one out myself. I'm a halfway-decent developer, right?". Well, once I started to think about it, I couldn't quite figure out how to go about it. I can crank out a data-driven website easily enough, or do a CMS implementation, or throw documents in and out of BizTalk all day. Can't begin to figure out how to compare HTML docs. Well, sure, I have to read the DOM, and iterate through the nodes. I have to map the structure to some data structure (how??), and then compare them (how??). It's a development task like none I've ever attempted. So now that I've identified a weakness in my knowledge, I'm even more challenged to figure this out. Any suggestions on how to get started? clarification: the actual content isn't what I want to compare -- the creative guys fill their pages with lorem ipsum, and I use real content. Instead, I want to compare structure: <div class="foo">lorem ipsum<div> is different that <div class="foo"><p>lorem ipsum<p><div>

  • Aliasing Resources (WPF)

    - by Noldorin
    I am trying to alias a resource in XAML, as follows: <UserControl.Resources> <StaticResourceExtension x:Key="newName" ResourceKey="oldName"/> </UserControl.Resources> oldName simply refers to a resource of type Image, defined in App.xaml. As far as I understand, this is the correct way to do this, and should work fine. However, the XAML code gives me the superbly unhelpful error: "The application XAML file failed to load. Fix errors in the application XAML before opening other XAML files." This appears when I hover over the StaticResourceExtension line in the code (which has a squiggly underline). Several other errors are generated in the actual Error List, but seem to be fairly irrelevant and nonsenical (such messages as "The name 'InitializeComponent' does not exist in the current context"), as they all disappear when the line is removed. I'm completely stumped here. Why is WPF complaining about this code? Any ideas as to a resolution please? Note: I'm using WPF in .NET 3.5 SP1. Update 1: I should clairfy that I do receive compiler errors (the aforementioned messages in the Error List), so it's not just a designer problem. Update 2: Here's the relevant code in full... In App.xaml (under Application.Resource): <Image x:Key="bulletArrowUp" Source="Images/Icons/bullet_arrow_up.png" Stretch="None"/> <Image x:Key="bulletArrowDown" Source="Images/Icons/bullet_arrow_down.png" Stretch="None"/> And in MyUserControl.xaml (under UserControl.Resources): <StaticResourceExtension x:Key="columnHeaderSortUpImage" ResourceKey="bulletArrowUp"/> <StaticResourceExtension x:Key="columnHeaderSortDownImage" ResourceKey="bulletArrowDown"/> These are the lines that generate the errors, of course.

  • Show NotifyIcon Context Menu and Control Its Position?

    - by Shawn O'Hern
    I'm trying to show a context menu when I left-click a NotifyIcon. Just calling NotifyIcon.ContextMenuStrip.Show() doesn't work very well. A solution has been posted here before that calls a secret method using Reflection: Dim mi As System.Reflection.MethodInfo = GetType(NotifyIcon).GetMethod("ShowContextMenu", Reflection.BindingFlags.Instance Or Reflection.BindingFlags.NonPublic) mi.Invoke(Icon, Nothing) This works great, except that I also need to control where the menu is shown. I want to wait for the SystemInformation.DoubleClickTime to elapse between receiving the NotifyIcon.MouseUp event and displaying the menu, so that I can handle single-clicks and double-clicks separately. But invoking the ShowContextMenu method displays the menu at the current mouse position when ShowContextMenu is called, not when the icon was actually clicked. Which means that if the mouse moved during the DoubleClickTime, the menu will be displayed in a different part of the screen. So if I can control where the menu is shown, I can just save the mouse coordinates when I receive the MouseUp event, and then I can ensure that the menu is displayed near the icon. Is there a way to do this? Thanks in advance.

  • jackson failing to map empty array with No content to map to Object due to end of input

    - by ijabz
    I send a query to an api and map the json results to my classes using Jackson. When I get some results it works fine, but when there are no results it fails with java.io.EOFException: No content to map to Object due to end of input at org.codehaus.jackson.map.ObjectMapper._initForReading(ObjectMapper.java:2766) at org.codehaus.jackson.map.ObjectMapper._readMapAndClose(ObjectMapper.java:2709) at org.codehaus.jackson.map.ObjectMapper.readValue(ObjectMapper.java:1854) at com.jthink.discogs.query.DiscogsServerQuery.mapQuery(DiscogsServerQuery.java:382) at com.jthink.discogs.query.SearchQuery.mapQuery(SearchQuery.java:37)* But the thing is the api isn't returning nothing at all, so I dont see why it is failing. Here is the query: http://api.discogs.com/database/search?page=1&type=release&release_title=nude+and+rude+the+best+of+iggy+pop this is what I get back { "pagination": { "per_page": 50, "pages": 1, "page": 1, "urls": {}, "items": 0 }, "results": [] } and here is the top level object Im trying to map to public class Search { private Pagination pagination; private Result[] results; public Pagination getPagination() { return pagination; } public void setPagination(Pagination pagination) { this.pagination = pagination; } public Result[] getResults() { return results; } public void setResults(Result[] results) { this.results = results; } } Im guessing the problem is something to do with the results array being returned being blank, but cant see what Im doing wrong EDIT: The comment below was correct, although I usually receive { "pagination": { "per_page": 50, "pages": 1, "page": 1, "urls": {}, "items": 0 }, "results": [] } and in these cases there is no problem but sometimes I seem to just get an empty String. Now Im wondering if the problem is how I read from the inputstream if (responseCode == HttpURLConnection.HTTP_OK) InputStreamReader in= new InputStreamReader(uc.getInputStream()); BufferedReader br= new BufferedReader(in); while(br.ready()) { String next = br.readLine(); sb.append(next); } return sb.toString(); } although I dont read until I get the response code, is it possible that the first time I call br.ready() that I call it before it is ready, and therefore I don't read the input EDIT 2: Changing above code to simply String line; while ((line = br.readLine()) != null) { sb.append(line); } resolved the issue.

  • Flash gets XML but the values are wrong, as3

    - by VideoDnd
    Flash receives the XML, but the values are wrong. How do I fix this? Problem I can see the XML loaded with no errors, but my output is way off. It's as though it's not receiving any values. Numbers in the output window and animation move rapidly. The Flash file runs as if it's variables where set to zero. I changed the order of my code, but that didn't help with this. Please explain how I can correct this.

  • Sharepoint BDC Error: The title property of entity tblStaff is set to an invalid value

    - by Christopher Rathermel
    I am just starting to create our Business Data Catalog(s) for our practice management system and I am running into an issue w/ our staff table. Background: I am using Business Data Catalog Definition Editor to create my ADF. I am using the RevertToSelf Authentication Mode. I have tried a few other tables and they seem to work just fine thus far.. only issue is w/ the staff table. If I removed all the columns for the staff entity except the ID and a few columns for the name it actually works. So it has a problem w/ one of my columns in tblStaff. I receive this error even when I set up an ADF w/ just this one entity. So w/ no associations.. When attempting to view the record: http://servername/ssp/admin/Content/tblstaff.aspx?StaffID={0} w/ {0} replaced w/ an actual staff ID I get the following error: The title property of entity tblStaff is set to an invalid value. Things I have tried: I noticed that I do have a column in my staff table called "Title" and removed it from ADF w/ no luck... Same error.. I tried to use bdc meta man to create my ADF and I got the same error... Any ideas? Chris

  • WCF events in server-side

    - by Eisenrich
    Hi all, I'm working on an application in WCF and want to receive events in the server side. I have a web that upon request needs to register a fingerprint. The web page request the connection of the device and then every second for 15 seconds requests the answer. The server-side code is apparently "simple" but doesn't work. Here is it: [ServiceContract] interface IEEtest { [OperationContract] void EEDirectConnect(); } class EETest : IEEtest { public void EEDirectConnect() { CZ ee = new CZ(); // initiates the device dll ee.Connect_Net("192.168.1.200", 4011); ee.OnFinger += new _IEEEvents_OnFingerEventHandler(ee_OnFinger); } public void ee_OnFinger() { //here i have a breakpoint; } } every time I put my finger, it should fire the event. in fact if I static void Main() { EETest pp = new EETest(); pp.EEDirectConnect(); } It works fine. but from my proxy it doesn't fire the event. do you have any tips, recommendations, or can you see the error? Thanks everyone.

  • JMS MessageCreator.createMessage() in Grails

    - by Hans Wurst
    Hi there, I am trying to implement jms to my grails application. I have several JMS consumer in a spring based enviroment listining on an ActiveMQ broker. I wrote a simple test commandline client which creates messages and receives them in an request response manner. Here is the snippet that sends a MapMessage in Spring JMS way. This works for me as long I am in my spring world. final String corrID = UUID.randomUUID().toString(); asyncJmsTemplate.send("test.RequestQ", new MessageCreator() { public Message createMessage(Session session) throws JMSException { try { MapMessage msg = session.createMapMessage(); msg.setStringProperty("json", mapper.writeValueAsString(List<of some objects>)); msg.setJMSCorrelationID(corrID); msg.setJMSReplyTo(session.createQueue("test.ReplyQ")); return msg; } catch (JsonGenerationException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (JsonMappingException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; } }); BUT when I tried to implement this methods to my grails test app I receive some METHOD_DEF exceptions. Sending simple TextMessages via the jmsTemplate.convertAndSende(Queue, Message) provided by the JMS Plugin works. Can any one help me? Is this a common problem? Cheers Hans

  • Android Home Screen Widget Failing with EditText

    Whenever I add an EditText widget to the layout of my home screen widget (confusing how the term "widget" is being used twice in the Android lexicon :-/ ), I receive the "Problem Loading Widget" error box. Here is the layout I'm attempting; if you remove the EditText, it works... < RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" <Button android:id="@+id/button_generate" android:layout_width="54px" android:layout_height="54px" android:text="Generate" android:textSize="10sp" android:gravity="center" android:layout_alignParentTop="true" android:layout_toRightOf="@+id/edittext_key"> </Button> <TextView android:id="@+id/textview_hash" android:layout_width="75px" android:layout_height="45px" android:text="Password" android:textSize="11sp" android:gravity="left" android:layout_alignParentTop="true" android:layout_toLeftOf="@+id/edittext_key"> </TextView> <EditText android:id="@+id/edittext_data2" android:layout_width="200px" android:layout_height="50px" android:textSize="12sp" android:layout_marginTop="20px" android:layout_alignParentTop="true" android:layout_centerHorizontal="true"> </EditText> </RelativeLayout> Now, the Google Search home screen widget has an EditText, so it's obviously legal to implement.

    Hi! I think I'm in a problem. I have two TCP apps connected to each other which use winsock I/O completion ports to send/receive data (non-blocking sockets). Everything works just fine until there's a data transfer burst. The sender starts sending incorrect/malformed data. I allocate the buffers I'm sending on the stack, and if I understand correctly, that's a wrong to do, because these buffers should remain as I sent them until I get the "write complete" notification from IOCP. Take this for example: void some_function() { char cBuff[1024]; // filling cBuff with some data WSASend(...); // sending cBuff, non-blocking mode // filling cBuff with other data WSASend(...); // again, sending cBuff // ..... and so forth! } If I understand correctly, each of these WSASend() calls should have its own unique buffer, and that buffer can be reused only when the send completes. Correct? Now, what strategies can I implement in order to maintain a big sack of such buffers, how should I handle them, how can I avoid performance penalty, etc'? And, if I am to use buffers that means I should copy the data to be sent from the source buffer to the temporary one, thus, I'd set SO_SNDBUF on each socket to zero, so the system will not re-copy what I already copied. Are you with me? Please let me know if I wasn't clear.

  • RegAsm for Class Library Used in VB6 Application

    - by michael.lukatchik
    To be short and to the point, I've built a C# class library that is both COM-Visible and Registered for COM Interop. I've compiled the library, which resulted in the generation of .dll and .tlb files. I have another machine that's running a VB6 application. So, I copied the .dll and .tlb files over to C:/Windows/system32 folder on the machine. I then registered those files using the following: C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm C:\Windows\system32\TestClass.dll /tlb:TestClass.tlb After the files were registered successfully, I added a project reference to the Test.tlb file from inside my VB6 app, then I tried to invoke a method in my new referenced class like so: Dim myObject As TestNamespace.TestClass Set myObject = New TestNamespace.TestClass MsgBox (myObject.TestMethod()) It doesn't work, and I receive a -2147024894 Automation Error. I've read that I shouldn't install the dll into a private folder like system32. I should either be registering in the GAC or I should be registering in another location using the "/codebase" option: C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm C:\TestClass.dll /tlb:TestClass.tlb /codebase Is there any reason I shouldn't be using system32? Past devs that have worked on this project have placed assembly files used by this VB6 project into system32 and there haven't seemed to be any issues. When I register my dll in the system32 location, I get the Automation Error. When I register my dll in another location (i.e. C:/), the method call into my class library from VB6 works as expected. What gives? I should mention that we will NOT be using the GAC to register any DLL's. That's just the way it is. Any help is appreciated. Mike

  • How to invalidate cache when benchmarking?

    - by Michael Buen
    I have this code, that when swapping the order of UsingAs and UsingCast, their performance also swaps. using System; using System.Diagnostics; using System.Linq; using System.IO; class Test { const int Size = 30000000; static void Main() { object[] values = new MemoryStream[Size]; UsingAs(values); UsingCast(values); Console.ReadLine(); } static void UsingCast(object[] values) { Stopwatch sw = Stopwatch.StartNew(); int sum = 0; foreach (object o in values) { if (o is MemoryStream) { var m = (MemoryStream)o; sum += (int)m.Length; } } sw.Stop(); Console.WriteLine("Cast: {0} : {1}", sum, (long)sw.ElapsedMilliseconds); } static void UsingAs(object[] values) { Stopwatch sw = Stopwatch.StartNew(); int sum = 0; foreach (object o in values) { if (o is MemoryStream) { var m = o as MemoryStream; sum += (int)m.Length; } } sw.Stop(); Console.WriteLine("As: {0} : {1}", sum, (long)sw.ElapsedMilliseconds); } } Outputs: As: 0 : 322 Cast: 0 : 281 When doing this... UsingCast(values); UsingAs(values); ...Results to this: Cast: 0 : 322 As: 0 : 281 When doing just this... UsingAs(values); ...Results to this: As: 0 : 322 When doing just this: UsingCast(values); ...Results to this: Cast: 0 : 322 Aside from running them independently, how to invalidate the cache so the second code being benchmarked won't receive the cached memory of first code? Benchmarking aside, just loved the fact that modern processors do this caching magic :-)

  • Cannot return view model after POST

    - by Interfector
    HI, I am trying to return a model after a POST but I receive the following error: Exception Details: System.InvalidOperationException: Operation is not valid due to the current state of the object. Line 29: public UsersModel getUser(Int32 id) { Line 30: return ( Line 31: from users in db.NUsers Line 32: join userSettings in db.NUsersSettings The code in the controller looks like this: [AcceptVerbs( HttpVerbs.Post )] public ActionResult Edit( NUsers user ) { //Other code that doesn't affect the error :) UsersModel userDetails = this.usersObj.getUser( user.UserID ); return View( userDetails ); } The getUser method looks like this: public UsersModel getUser(Int32 id) { return ( from users in db.NUsers join userSettings in db.NUsersSettings on users.UserID equals userSettings.UserID where users.UserID == id select new UsersModel { UserId = Convert.ToInt32( users.UserID ), Email = Convert.ToString( users.Email ), FirstName = Convert.ToString( users.FirstName ), LastName = Convert.ToString( users.LastName ), Language = Convert.ToString( userSettings.Language ), Phone = Convert.ToString( users.Phone ) } ).First(); } and finally the UsersModel if you think it is relevant: public class UsersModel { public int UserId; public string Email; public string FirstName; public string LastName; public string Language; public string Phone; public List<NLanguages> Languages; public UsersModel() { Models.Languages languagesObj = new Models.Languages(); Languages = languagesObj.getLanguages(); } } Any thoughts on what might be causing the error and what can I do to fix it? Thx

  • In C#, what thread will Events be handled in?

    - by Ben
    Hi, I have attempted to implement a producer/consumer pattern in c#. I have a consumer thread that monitors a shared queue, and a producer thread that places items onto the shared queue. The producer thread is subscribed to receive data...that is, it has an event handler, and just sits around and waits for an OnData event to fire (the data is being sent from a 3rd party api). When it gets the data, it sticks it on the queue so the consumer can handle it. When the OnData event does fire in the producer, I had expected it to be handled by my producer thread. But that doesn't seem to be what is happening. The OnData event seems as if it's being handled on a new thread instead! Is this how .net always works...events are handled on their own thread? Can I control what thread will handle events when they're raised? What if hundreds of events are raised near-simultaneously...would each have its own thread? Thank in advance! Ben

  • How do I Unit Test Actions without Mocking that use UpdateModel?

    - by Hellfire
    I have been working my way through Scott Guthrie's excellent post on ASP.NET MVC Beta 1. In it he shows the improvements made to the UpdateModel method and how they improve unit testing. I have recreated a similar project however anytime I run a UnitTest that contains a call to UpdateModel I receive an ArgumentNullException naming the controllerContext parameter. Here's the relevant bits, starting with my model: public class Country { public Int32 ID { get; set; } public String Name { get; set; } public String Iso3166 { get; set; } } The controller action: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Int32 id, FormCollection form) { using ( ModelBindingDataContext db = new ModelBindingDataContext() ) { Country country = db.Countries.Where(c => c.CountryID == id).SingleOrDefault(); try { UpdateModel(country, form); db.SubmitChanges(); return RedirectToAction("Index"); } catch { return View(country); } } } And finally my unit test that's failing: [TestMethod] public void Edit() { CountryController controller = new CountryController(); FormCollection form = new FormCollection(); form.Add("Name", "Canada"); form.Add("Iso3166", "CA"); var result = controller.Edit(2 /*Canada*/, form) as RedirectToRouteResult; Assert.IsNotNull(result, "Expected to be redirected on successful POST."); Assert.AreEqual("Show", result.RouteName, "Expected to redirect to the View action."); } ArgumentNullException is thrown by the call to UpdateModel with the message "Value cannot be null. Parameter name: controllerContext". I'm assuming that somewhere the UpdateModel requires the System.Web.Mvc.ControllerContext which isn't present during execution of the test. I'm also assuming that I'm doing something wrong somewhere and just need to pointed in the right direction. Help Please!

  • How do I POST/GET from rails to API with Nestful?

    - by Angela
    Hi, this is a pretty basic question but I'm not entirely clear how to do this. I am trying to use a third-party service that has web-based service. The service is called Postful. But I'm not clear what exactly to do? I've looked at ActiveResource (http://api.rubyonrails.org/classes/ActiveResource/Base.html) and rest-client, but I'm still not clear exactly what steps, code, and files to create. I'm trying to use Nestful but I'm not entirely clear how to make this work. http://github.com/maccman/nestful http://www.postful.com/service/mail is one of the services (details found http://www.postful.com/developer/guide#rest ), but to upload an image I have to post the following (but I'm not sure how I actually do this?). Thanks! > http://www.postful.com/service/upload > > Be sure to include the Content-Type > and Content-Length headers and the > image itself as the body of the > request. > > POST /upload HTTP/1.0 Content-Type: > application/octet-stream > Content-Length: 301456 > > ... file content here ... > > If the upload is successful, you will > receive a response like the following: > > <?xml version="1.0" encoding="UTF-8"?> > <upload> > <id>290797321.waltershandy.2</id> > </upload>
