  • Why might stable_sort be affecting my hashtable values?

    - by zebraman
    I have defined a struct ABC to contain an int ID, string NAME, string LAST_NAME; My procedure is this: Read in a line from an input file. Parse each line into first name and last name and insert into the ABC struct. Also, the struct's ID is given by the number of the input line. Then, push_back the struct into a vector masterlist. I am also hashing these to a hashtable defined as vector< vector , using first name and last name as keywords. That is, If my data is: Garfield Cat Snoopy Dog Cat Man Then for the keyword cash hashes to a vector containing Garfield Cat and Cat Man. I insert the structs into the hashtable using push_back again. The problem is, when I call stable_sort on my masterlist, my hashtable is affected for some reason. I thought it might be happening since the songs are being ordered differently, so I tried making a copy of the masterlist and sorting it and it still affects the hashtable though the original masterlist is unaffected. Any ideas why this might be happening?

  • T4MVC not generating an action

    - by Maslow
    I suspected there was some hidden magic somewhere that stopped what looks like actual method calls all over the place in T4MVC. Then I had a view fail to compile, and the stackTrace went into my actual method. [Authorize] public string Apply(string shortName) { if (shortName.IsNullOrEmpty()) return "Failed alliance name was not transmitted"; if (Request.IsAuthenticated == false || User == null || User.Identity == null) return "Apply authentication failed"; Models.Persistence.AlliancePersistance.Apply(User.Identity.Name, shortName); return "Applied"; } So this method isn't generating in the template after all. <%=Ajax.ActionLink("Apply", "Apply", new RouteValueDictionary() { { "shortName", item.Shortname } }, new AjaxOptions() { UpdateTargetId = "masterstatus" })%> <%=Html.ActionLink("Apply",MVC.Alliance.Apply(item.Shortname),new AjaxOptions() { UpdateTargetId = "masterstatus" }) %> The second method threw an exception on compile because the method Apply in my controller has an [Authorize] attribute so that if someone that isn't logged on clicks this, they get redirected to login, then right back to this page. There they can click on apply again, this time being logged in. And yes I realize one is Ajax.ActionLink while the other is Html.ActionLink I did try them both with the T4MVC version.

  • How can i use Google-o-Meter or Google Vizualisation API with Jenkins

    - by kamal
    Here is a sample that displays a static chart: google.load("visualization", "1.0", {packages:["imagechart"]}); google.setOnLoadCallback(drawChart); function drawChart() { var dataTable = new google.visualization.DataTable(); dataTable.addColumn('string'); dataTable.addColumn('number'); dataTable.addColumn('string'); // Row data is [chl, data point, point label] dataTable.addRows([ ['January',40,undefined], ['February',60,'Initial recall'], ['March',60,'Product withdrawn'], ['April',45,undefined], ['May',47,'Relaunch'], ['June',75,undefined], ['July',70,undefined], ['August',72,undefined] ]); var options = {cht: 'lc', chds:'0,160', annotationColumns:[{column:2, size:12, type:'flag', priority:'high'},]}; var chart = new google.visualization.ImageChart(document.getElementById('line_div')); chart.draw(dataTable, options); } How can i replace the static values and variables in dataTable.addRows([ with real live data ? In case the compete code is not visible, refer to : http://code.google.com/apis/visualization/documentation/gallery/genericimagechart.html When this Javascript is copied to the "Description" it renders a chart, what i want to know is how to replace the name/value in dataTable.addRows, to the name/values coming from Jenkins

  • Get an Arduino and Android phone to communicate over the web

    - by Saleem
    I am writing an Android application to communicate with my Arduino over the web. The Arduino is running a web server through an Ethernet shield. I am attaching my code, but I will explain it here so you will understand what I am trying to do. The Android sends an HTTP request in the format http://192.168.1.148/?Lights=1. The Arduino gets the request, executes the command (in this case turning on some lights) and then responds to the Android device by simply sending the string "Lights=On". The Android will then change the color of the button to notify the user that the command was executed successfully. The Arduino is getting the instruction and executing it and sending the response but my button color is not changing. I know that the Android device is getting the string because I added a debug line to change the text on the button to the received response. The relevant code for the Android device is: ((Button) v).setText(sb.toString()); //This works and the button text changes to "Lights=On". //Test response and update button if(sb.toString()=="Lights=On"){ v.getBackground().setColorFilter(0xFFFFFF00, PorterDuff.Mode.MULTIPLY); Drawable d = lightOff.getBackground(); lightOff.invalidateDrawable(d); d.clearColorFilter(); } The Arduino code is: if(s=="Lights"){ switch(client.read()){ case '0': digitalWrite(LightPin,0); client.print("Lights=Off"); //debug Serial.println("Lights=Off"); break; case '1': digitalWrite(LightPin,1); client.print("Lights=On"); Serial.println("Lights=On"); break; } } Please let me know if you need more of the code to answer this question.

  • LINQ Query please help C#.Net.

    - by Paul Matthews
    I'm very new to LINQ and struggling to find the answers. I have a simple SQL query. Select ID, COUNT(ID) as Selections, OptionName, SUM(Units) as Units FROM tbl_Results GROUP BY ID, OptionName. The results I got were: '1' '4' 'Approved' '40' '2' '1' 'Rejected' '19' '3' '2' 'Not Decided' '12' Due to having to encrypt all my data in the database I'm unable to do sums. Therefore I have now brought back the data and decrypt it in the application layer. Results would be: '1' 'Approved' '10' '3' 'Not Deceided' '6' '2' 'Rejected' '19' '1' 'Approved' '15' '1' 'Approved' '5' '3' 'Not Deceided' '6' '1' 'Approved' '10' using a simple class I have called back the above results, and put them in a list class. public class results { public int ID {get;set;} public string OptionName {get;set;} public int Unit {get;set;} } I almost have the LINQ query to bring back the results like the SQL query at the top var q = from r in Results group p.Unit by p.ID int g select new {ID = g.Key, Selections = g.Count(), Units = g.Sum()}; How do I ensure my LINQ query also give me the Option Name? Also if I created a class called Statistics to hold my results how would I modify the LINQ query to give me list result set? public class results { public int ID {get;set;} public int NumberOfSelections { get; set; } public string OptionName {get;set;} public int UnitTotal {get;set;} }

  • Background worker not working right

    - by vbNewbie
    I have created a background worker to go and run a pretty long task that includes creating more threads which will read from a file of urls and crawl each. I tried following it through debugging and found that the background process ends prematurely for no apparent reason. Is there something wrong in the logic of my code that is causing this. I will try and paste as much as possible to make sense. While Not myreader.EndOfData Try currentRow = myreader.ReadFields() Dim currentField As String For Each currentField In currentRow itemCount = itemCount + 1 searchItem = currentField generateSearchFromFile(currentField) processQuerySearch() Next Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException Console.WriteLine(ex.Message.ToString) End Try End While This first bit of code is the loop to input from file and this is what the background worker does. The next bit of code is where the background worker creates threads to work all the 'landingPages'. After about 10 threads are created the background worker exits this sub and skips the file input loop and exits the program. Try For Each landingPage As String In landingPages pgbar.Timer1.Stop() If VisitedPages.Contains(landingPage) Then Continue For Else Dim thread = New Thread(AddressOf processQuery) count = count + 1 thread.Name = "Worm" & count thread.Start(landingPage) If numThread >= 10 Then For Each thread In ThreadList thread.Join() Next numThread = 0 Continue For Else numThread = numThread + 1 SyncLock ThreadList ThreadList.Add(thread) End SyncLock End If End If Next

  • How to make Facebook Authentication from Silverlight secure?

    - by SondreB
    I have the following scenario I want to complete: Website running some HTTP(S) services that returns data for a user. Same website is additionally hosting a Silverlight 4 app which calls these services. The Silverlight app is integrating with Facebook using the Facebook Developer Toolkit (http://facebooktoolkit.codeplex.com/). I have not fully decided whether I want Facebook-integration to be a "opt-in" option such as Spotify, or if I want to "lock" down my service with Facebook-only authentication. That's another discussion. How do I protect my API Key and Secret that I receive from Facebook in a Silverlight app? To me it's obvious that this is impossible as the code is running on the client, but is there a way I can make it harder or should I just live with the fact that third parties could potentially "act" as my own app? Using the Facebook Developer Toolkit, there is a following C# method in Silverlight that is executed from the JavaScript when the user has fully authenticated with Facebook using the Facebook Connect APIs. [ScriptableMember] public void LoggedIn(string sessionKey, string secret, int expires, long userId) { this.SessionKey = sessionKey; this.UserId = userId; Obvious the problem here is the fact that JavaScript is injection the userId, which is nothing but a simple number. This means anyone could potentially inject a different userId in JavaScript and have my app think it's someone else. This means someone could hijack the data within the services running on my website. The alternative that comes to mind is authenticating the users on my website, this way I'm never exposing any secrets and I can return an auth-cookie to the users after the initial authentication. Though this scenario doesn't work very well in an out-of-browser scenario where the user is running the Silverlight app locally and not from my website.

  • Saving twice don't update my object in JDO

    - by Javi
    Hello I have an object persisted in the GAE datastore using JDO. The object looks like this: public class MyObject implements Serializable, StoreCallback { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) @Extension(vendorName="datanucleus", key="gae.encoded-pk", value="true") private String id; @Persistent private String firstId; ... } As usually when the object is stored for the first time a new id value is generated for the identifier. I need that if I don't provide a value for firstId it sets the same value as the id. I don't want to solve it with a special getter which checks for null value in firstId and then return the id value because I want to make queries relating on firstId. I can do it in this way by saving the object twice (Probably there's a better way to do this, but I'll do it in this way until I find a better one). But it is not working. when I debug it I can see that result.firstId is set with the id value and it seems to be persisted, but when I go into the datastore I see that firstId is null (as it was saved the first time). This save method is in my DAO and it is called in another save method in the service annotated with @Transactional. Does anyone have any idea why the second object in not persisted properly? @Override public MyObject save(MyObject obj) { PersistenceManager pm = JDOHelper.getPersistenceManagerFactory("transactions-optional"); MyObject result = pm.makePersistent(obj); if(result.getFirstId() == null){ result.setFirstId(result.getId()); result = pm.makePersistent(result); } return result; } Thanks.

  • WCF object parameter loses values

    - by Josh
    I'm passing an object to a WCF service and wasn't getting anything back. I checked the variable as it gets passed to the method that actually does the work and noticed that none of the values are set on the object at that point. Here's the object: [DataContract] public class Section { [DataMember] public long SectionID { get; set; } [DataMember] public string Title { get; set; } [DataMember] public string Text { get; set; } [DataMember] public int Order { get; set; } } Here's the service code for the method: [OperationContract] public List<Section> LoadAllSections(Section s) { return SectionRepository.Instance().LoadAll(s); } The code that actually calls this method is this and is located in a Silverlight XAML file: SectionServiceClient proxy = new SectionServiceClient(); proxy.LoadAllSectionsCompleted += new EventHandler<LoadAllSectionsCompletedEventArgs>(proxy_LoadAllSectionsCompleted); Section s = new Section(); s.SectionID = 4; proxy.LoadAllSectionsAsync(s); When the code finally gets into the method LoadAllSections(Section s), the parameter's SectionID is not set. I stepped through the code and when it goes into the generated code that returns an IAsyncResult object, the object's properties are set. But when it actually calls the method, LoadAllSections, the parameter received is completely blank. Is there something I have to set to make the proeprty stick between method calls?

  • Rails 2.3.2 trying to render ERB instead of HAML

    - by c00lryguy
    Rails is suddenly trying to render ERB instead of Haml and I can't figure out why. I've created new rails projects, reinstalled Haml, and reinstalled Rails. Here's exactly the steps I take when making my application (Rails 2.3.2): rails> rails test rails> cd test rails\test> haml --rails . rails\test> ruby script\generate model user email:string password:string rails\test> ruby script\generate controller users index rails\test> rake db:migrate Here's what the UsersController looks like: class UsersController < ApplicationController def index @users = User.all end end My routes: ActionController::Routing::Routes.draw do |map| map.resources :users end I now create views\users\index.html.haml: %table %th(style="text-align: left;") %h1 Users - for user in @users %tr %td= user.email %td= user.password Annnd run the server... I navigate to localhost:3000\users and I get this error message: Template is missing Missing template users/index.erb in view path app/views For some reason Rails is trying to find and render .erb files instead of .haml files. vendor\plugins\haml\init.rb exists, untouched. I've reinstalled Haml (Pretty Penny) multiple times and still get the same results. I've also tried adding config.gem 'haml' to my environment.rb but this also doesn't work. I can't figure out why suddenly rails will not render haml for me.

  • Why does findstr not handle case properly (in some circumstances)?

    - by paxdiablo
    While writing some recent scripts in cmd.exe, I had a need to use findstr with regular expressions - customer required standard cmd.exe commands (no GnuWin32 nor Cygwin nor VBS nor Powershell). I just wanted to know if a variable contained any upper-case characters and attempted to use: > set myvar=abc > echo %myvar%|findstr /r "[A-Z]" abc > echo %errorlevel% 0 When %myvar% is set to abc, that actually outputs the string and sets errorlevel to 0, saying that a match was found. However, the full-list variant: > echo %myvar%|findstr /r "[ABCDEFGHIJKLMNOPQRSTUVWXYZ]" > echo %errorlevel% 1 does not output the line and it correctly sets errorlevel to 1. In addition: > echo %myvar%|findstr /r "^[A-Z]*$" > echo %errorlevel% 1 also works as expected. I'm obviously missing something here even if it's only the fact that findstr is somehow broken. Why does the first (range) regex not work in this case? And yet more weirdness: > echo %myvar%|findstr /r "[A-Z]" abc > echo %myvar%|findstr /r "[A-Z][A-Z]" abc > echo %myvar%|findstr /r "[A-Z][A-Z][A-Z]" > echo %myvar%|findstr /r "[A]" The last two above also does not output the string!!

  • How to include a child object's child object in Entity Framework 5

    - by Brendan Vogt
    I am using Entity Framework 5 code first and ASP.NET MVC 3. I am struggling to get a child object's child object to populate. Below are my classes.. Application class; public class Application { // Partial list of properties public virtual ICollection<Child> Children { get; set; } } Child class: public class Child { // Partial list of properties public int ChildRelationshipTypeId { get; set; } public virtual ChildRelationshipType ChildRelationshipType { get; set; } } ChildRelationshipType class: public class ChildRelationshipType { public int Id { get; set; } public string Name { get; set; } } Part of GetAll method in the repository to return all the applications: return DatabaseContext.Applications .Include("Children"); The Child class contains a reference to the ChildRelationshipType class. To work with an application's children I would have something like this: foreach (Child child in application.Children) { string childName = child.ChildRelationshipType.Name; } I get an error here that the object context is already closed. How do I specify that each child object must include the ChildRelationshipType object like what I did above?

  • Can Castle.Windsor do automatic resolution of concrete types

    - by Anthony
    We are evaluating IoC containers for C# projects, and both Unity and Castle.Windsor are standing out. One thing that I like about Unity (NInject and StructureMap also do this) is that types where it is obvious how to construct them do not have to be registered with the IoC Container. Is there way to do this in Castle.Windsor? Am I being fair to Castle.Windsor to say that it does not do this? Is there a design reason to deliberately not do this, or is it an oversight, or just not seen as important or useful? I am aware of container.Register(AllTypes... in Windsor but that's not quite the same thing. It's not entirely automatic, and it's very broad. To illustrate the point, here are two NUnit tests doing the same thing via Unity and Castle.Windsor. The Castle.Windsor one fails. : namespace SimpleIocDemo { using NUnit.Framework; using Castle.Windsor; using Microsoft.Practices.Unity; public interface ISomeService { string DoSomething(); } public class ServiceImplementation : ISomeService { public string DoSomething() { return "Hello"; } } public class RootObject { public ISomeService SomeService { get; private set; } public RootObject(ISomeService service) { SomeService = service; } } [TestFixture] public class IocTests { [Test] public void UnityResolveTest() { UnityContainer container = new UnityContainer(); container.RegisterType<ISomeService, ServiceImplementation>(); // Root object needs no registration in Unity RootObject rootObject = container.Resolve<RootObject>(); Assert.AreEqual("Hello", rootObject.SomeService.DoSomething()); } [Test] public void WindsorResolveTest() { WindsorContainer container = new WindsorContainer(); container.AddComponent<ISomeService, ServiceImplementation>(); // fails with exception "Castle.MicroKernel.ComponentNotFoundException: // No component for supporting the service SimpleIocDemo.RootObject was found" // I could add // container.AddComponent<RootObject>(); // but that approach does not scale RootObject rootObject = container.Resolve<RootObject>(); Assert.AreEqual("Hello", rootObject.SomeService.DoSomething()); } } }

Here's the code: class Program { static void Main(string[] args) { using (var documentStore = new DocumentStore() { Url = "http://localhost:8080" }) { documentStore.Initialise(); documentStore.DatabaseCommands.PutIndex( "BasicEntityBySomeData", new IndexDefinition<BasicEntity, BasicEntity>() { Map = docs => from doc in docs where doc.SomeData != null select new { SomeData = doc.SomeData }, }); string entityId; using (var documentSession = documentStore.OpenSession()) { var entity = new BasicEntity() { SomeData = "Hello, World!", SomeOtherData = "This is just another property", }; documentSession.Store(entity); documentSession.SaveChanges(); entityId = entity.Id; var loadedEntity = documentSession.Load<BasicEntity>(entityId); Console.WriteLine(loadedEntity.SomeData); var docs = documentSession.Query<BasicEntity>("BasicEntityBySomeData") .Where("SomeData:Hello~") .WaitForNonStaleResults() .ToArray(); docs.ToList().ForEach(doc => Console.WriteLine(doc.SomeData)); Console.Read(); } } } It throws the 401 error when on the line that makes the PutIndex() call. Any ideas what permissions I need to apply? And where I need to apply them?

  • handling DATETIME values 0000-00-00 00:00:00 in JDBC

    - by Jason S
    I get an exception (see below) if I try to do resultset.getString("add_date"); for a JDBC connection to a MySQL database containing a DATETIME value of 0000-00-00 00:00:00 (the quasi-null value for DATETIME), even though I'm just trying to get the value as string, not as an object. I got around this by doing SELECT CAST(add_date AS CHAR) as add_date which works, but seems silly... is there a better way to do this? My point is that I just want the raw DATETIME string, so I can parse it myself as is. note: here's where the 0000 comes in: (from http://dev.mysql.com/doc/refman/5.0/en/datetime.html) Illegal DATETIME, DATE, or TIMESTAMP values are converted to the “zero” value of the appropriate type ('0000-00-00 00:00:00' or '0000-00-00'). The specific exception is this one: SQLException: Cannot convert value '0000-00-00 00:00:00' from column 5 to TIMESTAMP. SQLState: S1009 VendorError: 0 java.sql.SQLException: Cannot convert value '0000-00-00 00:00:00' from column 5 to TIMESTAMP. at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1055) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:956) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:926) at com.mysql.jdbc.ResultSetImpl.getTimestampFromString(ResultSetImpl.java:6343) at com.mysql.jdbc.ResultSetImpl.getStringInternal(ResultSetImpl.java:5670) at com.mysql.jdbc.ResultSetImpl.getString(ResultSetImpl.java:5491) at com.mysql.jdbc.ResultSetImpl.getString(ResultSetImpl.java:5531)

  • Extracting specific nodes from XML using XML::Twig

    - by pratz
    i was trying to extract a particular set of nodes from the following XML structure using XML::Twig, but have been stuck ever since. I need to extract the 'player' nodes from the following structure and do a string match/replace on each of these node values. <pep:record> <agency> <subrecord type="scout"> <isnum>123XXX (print)</isnum> <isnum>234YYY (mag)</isnum> </subrecord> <subrecord type="group"> </subrecord> </agency </record> I tried using the following code, but I get pointed to a hash reference rather than actual string. my $parser = XML::Twig->new(twig_handlers => { isnum => sub { print $_->text."::" }, }); foreach my $rec (split(/::/, $parser->parse($my_xml))) { if ($rec =~ m/print/) { ($print = $rec) =~ s/( \(print\))//; } elsif($rec =~ m/mag/) { ($mag = $rec) =~ s/( \(mag\))//; } }

  • WCF Callbacks often break

    - by cdecker
    I'm having quite some trouble with the WCF Callback mechanism. They sometimes work but most of the time they don't. I have a really simple Interface for the callbacks to implement: public interface IClientCallback { [OperationContract] void Log(string content); } I then implmenent that interface with a class on the client: [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)] [ServiceContract] internal sealed class ClientCallback : IClientCallback { public void Log(String content){ Console.Write(content); } } And on the client I finally connect to the server: NetTcpBinding tcpbinding = new NetTcpBinding(SecurityMode.Transport); EndpointAddress endpoint = new EndpointAddress("net.tcp://127.0.0.1:1337"); ClientCallback callback= new ClientCallback(); DuplexChannelFactory<IServer> factory = new DuplexChannelFactory<IServer>(callback,tcpbinding, endpoint); factory.Open(); _connection = factory.CreateChannel(); ((ICommunicationObject)_connection).Faulted += new EventHandler(RecreateChannel); try { ((ICommunicationObject)_connection).Open(); } catch (CommunicationException ce) { Console.Write(ce.ToString()); } To invoke the callback I use the following: OperationContext.Current.GetCallbackChannel().Log("Hello World!"); But it just hangs there, and after a while the client complains about timeouts. Is there a simple solution as to why?

  • Optimizing drawing on UITableViewCell

    - by Brian
    I am drawing content to a UITableViewCell and it is working well, but I'm trying to understand if there is a better way of doing this. Each cell has the following components: Thumbnail on the left side - could come from server so it is loaded async Title String - variable length so each cell could be different height Timestamp String Gradient background - the gradient goes from the top of the cell to the bottom and is semi-transparent so that background colors shine through with a gloss It currently works well. The drawing occurs as follows: UITableViewController inits/reuses a cell, sets needed data, and calls [cell setNeedsDisplay] The cell has a CALayer for the thumbnail - thumbnailLayer In the cell's drawRect it draws the gradient background and the two strings The cell's drawRect it then calls setIcon - which gets the thumbnail and sets the image as the contents of the thumbnailLayer. If the image is not found locally, it sets a loading image as the contents of the thumbnailLayer and asynchronously gets the thumbnail. Once the thumbnail is received, it is reset by calling setIcon again & resets the thumbnailLayer.contents This all currently works, but using Instruments I see that the thumbnail is compositing with the gradient. I have tried the following to fix this: setting the cell's backgroundView to a view whose drawRect would draw the gradient so that the cell's drawRect could draw the thumbnail and using setNeedsDisplayInRect would allow me to only redraw the thumbnail after it loaded --- but this resulted in the backgroundView's drawing (gradient) covering the cell's drawing (text). I would just draw the thumbnail in the cell's drawRect, but when setNeedsDisplay is called, drawRect will just overlap another image and the loading image may show through. I would clear the rect, but then I would have to redraw the gradient. I would try to draw the gradient in a CAGradientLayer and store a reference to it, so I can quickly redraw it, but I figured I'd have to redraw the gradient if the cell's height changes. Any ideas? I'm sure I'm missing something so any help would be great.

  • Is there a way to get an ASMX Web Service created in VS 2005 to receive and return JSON?

    - by Ben McCormack
    I'm using .NET 2.0 and Visual Studio 2005 to try to create a web service that can be consumed both as SOAP/XML and JSON. I read Dave Ward's Answer to the question How to return JSON from a 2.0 asmx web service (in addition to reading other articles at Encosia.com), but I can't figure out how I need to set up the code of my asmx file in order to work with JSON using jQuery. Two Questions: How do I enable JSON in my .NET 2.0 ASMX file? What's a simple jQuery call that could consume the service using JSON? Also, I notice that since I'm using .NET 2.0, I i'm not able to implement using System.Web.Script.Services.ScriptService. Here's my C# code for the demo ASMX service: using System; using System.Web; using System.Collections; using System.Web.Services; using System.Web.Services.Protocols; /// <summary> /// Summary description for StockQuote /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class StockQuote : System.Web.Services.WebService { public StockQuote () { //Uncomment the following line if using designed components //InitializeComponent(); } [WebMethod] public decimal GetStockQuote(string ticker) { //perform database lookup here return 8; } [WebMethod] public string HelloWorld() { return "Hello World"; } } Here's a snippet of jQuery I found on the internet and tried to modify: $(document).ready(function(){ $("#btnSubmit").click(function(event){ $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "http://bmccorm-xp/WebServices/HelloWorld.asmx", data: "", dataType: "json" }) event.preventDefault(); }); });

  • WCF and streaming requests and responses

    - by Cheeso
    Is it correct that in WCF, I cannot have a service write to a stream that is received by the client? My understanding is that streaming is supported in WCF for requests, responses, or both. Is it true that in all cases, the receiver of the stream must invoke Read ? I would like to support a scenario where the receiver of the stream can Write on it. Is this supported? Let me show it this way. The simplest example of Streaming in WCF is the service returning a FileStream to a client. This is a streamed response. The server code is like this: [ServiceContract] public interface IStreamService { [OperationContract] Stream GetData(string fileName); } public class StreamService : IStreamService { public Stream GetData(string filename) { FileStream fs = new FileStream(filename, FileMode.Open) return fs; } } And the client code is like this: StreamDemo.StreamServiceClient client = new WcfStreamDemoClient.StreamDemo.StreamServiceClient(); Stream str = client.GetData(@"c:\path\to\myfile.dat"); do { b = str.ReadByte(); //read next byte from stream ... } while (b != -1); (example taken from http://blog.joachim.at/?p=33) Clear, right? The server returns the Stream to the client, and the client invokes Read on it. Is it possible for the client to provide a Stream, and the server to invoke Write on it? In other words, rather than a pull model - where the client pulls data from the server - it is a push model, where the client provides the "sink" stream and the server writes into it. Is this possible in WCF, and if so, how? What are the config settings required for the binding, interface, etc? The analogy is the Response.OutputStream from an ASP.NET request. In ASPNET, any page can invoke Write on the output stream, and the content is received by the client. Can I do something similar in WCF? Thanks.

  • How to render a DateTime in a specific format in ASP.NET MVC 3?

    - by Slauma
    If I have in my model class a property of type DateTime how can I render it in a specific format - for example in the format which ToLongDateString() returns? I have tried this... @Html.DisplayFor(modelItem => item.MyDateTime.ToLongDateString()) ...which throws an exception because the expression must point to a property or field. And this... @{var val = item.MyDateTime.ToLongDateString(); Html.DisplayFor(modelItem => val); } ...which doesn't throw an exception, but the rendered output is empty (although val contains the expected value, as I could see in the debugger). Thanks for tips in advance! Edit ToLongDateString is only an example. What I actually want to use instead of ToLongDateString is a custom extension method of DateTime and DateTime?: public static string FormatDateTimeHideMidNight(this DateTime dateTime) { if (dateTime.TimeOfDay == TimeSpan.Zero) return dateTime.ToString("d"); else return dateTime.ToString("g"); } public static string FormatDateTimeHideMidNight(this DateTime? dateTime) { if (dateTime.HasValue) return dateTime.Value.FormatDateTimeHideMidNight(); else return ""; } So, I think I cannot use the DisplayFormat attribute and DataFormatString parameter on the ViewModel properties.

  • Mailing Address is forcing 2nd Record in CSV (DevExpress Controls)

    - by Gerhard Weiss
    My DevExpress CSV export has two lines per record. Rank Score,Prog.,Full Address 63.30 ,JIW ,1234 Whispering Pines Dr , ,Sometown MI 48316 62.80 ,JIW ,9876 Beagle Dr , ,Sometown Twp MI 48382 I would like to change it to one line because I want to do a Word Merge. (Unless Word can merge these two lines back together, which I do not thing it can do) Does the DevExpress XtraGrid ExportToText allow for this? A MemoEdit is being used by the XtraGrid and is initialized using the following code (Noticed the ControlChars.NewLine): Public ReadOnly Property FullAddress() As String Get Dim strAddress As System.Text.StringBuilder = New StringBuilder() If Not IsNullEntity Then strAddress.Append(Line1 + ControlChars.NewLine) If Not Line2 Is Nothing AndAlso Me.Line2.Length > 0 Then strAddress.Append(Line2 + ControlChars.NewLine) End If If Not Line3 Is Nothing AndAlso Me.Line3.Length > 0 Then strAddress.Append(Line3 + ControlChars.NewLine) End If strAddress.Append(String.Format("{0} {1} {2}", City, RegionCode, PostalCode)) If Me.Country <> "UNITED STATES" Then strAddress.Append(ControlChars.NewLine + Me.Country) End If End If Return strAddress.ToString End Get End Property Here is the export to CSV code: Dim saveFile As New SaveFileDialog With saveFile '.InitialDirectory = ClientManager.CurrentClient.Entity.StudentPictureDirectory .FileName = "ApplicantList.csv" .CheckPathExists = True .CheckFileExists = False .Filter = "All Files (*.*)|*.*" End With If saveFile.ShowDialog() = Windows.Forms.DialogResult.OK Then Dim PrintingTextExportOptions As New DevExpress.XtraPrinting.TextExportOptions(",", Encoding.ASCII) PrintingTextExportOptions.QuoteStringsWithSeparators = True ApplicantRankListViewsGridControl.ExportToText(saveFile.FileName, PrintingTextExportOptions) End If
