  • Model Binding, a simple, simple question

    - by Paul Hatcherian
    I have a struct which works much like the System.Nullable type: public struct SpecialProperty<T> { public static implicit operator T(SpecialProperty<T> value) { return value.Value; } public static implicit operator SpecialProperty<T>(T value) { return new TrackChanges<T> { Value = value }; } T internalValue; public T Value { get { return internalValue; } set { internalValue = value; } } public override bool Equals(object other) { return Value.Equals(other); } public override int GetHashCode() { return Value.GetHashCode(); } public override string ToString() { return Value.ToString(); } } I'm trying to use it with ASP.NET MVC binding. Using the default customer model binder the property will always yield null. I can fix this by adding ".Value" to the end of every form input name, but I just want it to bind to the new type directly using some sort of custom model binder, but all the solutions I've tried seemed needlessly complex. I feel like I should be able to extend the default binder and with a few lines of code redirect the property binding to the entire model using implicit conversion. I don't quite get the binding paradigm of the default binder, but it seems really stuck on this distinction between the model and model properties. What is the simplest method to do this? Thanks!

  • Code required to use foreach on my own custom appSettings

    - by jamauss
    I've searched the site and haven't found exactly what I'm looking for. Close, but no cigar. Basically I want to have a config section like this: <configSections> <section name="PhoneNotificationsSection" type="Alerts.PhoneAlertConfigSection,Alerts,Version=1.0.0.0,Culture=neutral,PublicKeyToken=null"/> </configSections> <PhoneNotificationsSection> <phones> <add phone="MyMobile" value="[email protected]" /> <add phone="OtherMobile" value="[email protected]" /> </phones> </PhoneNotificationsSection> Then I'd like to, in my appSettings consuming code, be able to write something like this (pseudo code): foreach (phone p in phones) { //'phone' attribute is just helpful/descriptive DoSomething(p.value); } I've done enough research to know I probably need a few of my own classes that implement and/or inherit from certain Configuration classes to make the above code possible. I just haven't found anything that clearly demonstrates this scenario and how to code for it - and when I try to learn the whole .NET configuration world my brain starts to hurt. Anyone have some code like what I'm looking for that they can share?

  • Creating A Single Generic Handler For Agatha?

    - by David
    I'm using the Agatha request/response library (and StructureMap, as utilized by Agatha 1.0.5.0) for a service layer that I'm prototyping, and one thing I've noticed is the large number of handlers that need to be created. It generally makes sense that any request/response type pair would need their own handler. However, as this scales to a large enterprise environment that's going to be A LOT of handlers. What I've started doing is dividing up the enterprise domain into logical processor classes (dozens of processors instead of many hundreds or possibly eventually thousands handlers). The convention is that each request/response type (all of which inherit from a domain base request/response pair, which inherit from Agatha's) gets exactly one function in a processor somewhere. The generic handler (which inherits from Agatha's RequestHandler) then uses reflection in the Handle method to find the method for the given TREQUEST/TRESPONSE and invoke it. If it can't find one or if it finds more than one, it returns a TRESPONSE containing an error message (messages are standardized in the domain's base response class). The goal here is to allow developers across the enterprise to just concern themselves with writing their request/response types and processor functions in the domain and not have to spend additional overhead creating handler classes which would all do exactly the same thing (pass control to a processor function). However, it seems that I still need to have defined a handler class (albeit empty, since the base handler takes care of everything) for each request/response type pair. Otherwise, the following exception is thrown when dispatching a request to the service: StructureMap Exception Code: 202 No Default Instance defined for PluginFamily Agatha.ServiceLayer.IRequestHandler`1[[TSFG.Domain.DTO.Actions.HelloWorldRequest, TSFG.Domain.DTO, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], Agatha.ServiceLayer, Version=1.0.5.0, Culture=neutral, PublicKeyToken=6f21cf452a4ffa13 Is there a way that I'm not seeing to tell StructureMap and/or Agatha to always use the base handler class for all request/response type pairs? Or maybe to use Reflection.Emit to generate empty handlers in memory at application start just to satisfy the requirement? I'm not 100% familiar with these libraries and am learning as I go along, but so far my attempts at both those possible approaches have been unsuccessful. Can anybody offer some advice on solving this, or perhaps offer another approach entirely?

  • setAnimationRepeatAutoreverses not behaved as I expected

    - by danielkwan
    I am starting to learn to use UIView animation. So I wrote the following lines: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2.0]; [UIView setAnimationRepeatCount:2]; [UIView setAnimationRepeatAutoreverses:YES]; CGPoint position = greenView.center; position.y = position.y + 100.0f; position.x = position.x + 100.0f; greenView.center = position; [UIView commitAnimations]; In this case, the UIView (a green box) moved back and fore 2 times. So far so good, BUT I found out that after the moving twice, the green box ended up jumped to the "new position" (position.x + 100.0f, position.y + 100.0f) instead of going back to the original position (position.x, position.y). That makes the animation look pretty odd (like after the box swing back to the original position caused by setAnimationRepeatAutoreverses, it jumps back to the new position in the last microsecond!) What is the best way to make the green box NOT jump to the new position at the very last minute?

  • Why is ExecuteFunction method only available through base.ExecuteFunction in a child class of Object

    - by Matt
    I'm trying to call ObjectContext.ExecuteFunction from my objectcontext object in the repository of my site. The repository is generic, so all I have is an ObjectContext object, rather than one that actually represents my specific one from the Entity Framework. Here's an example of code that was generated that uses the ExecuteFunction method: [global::System.CodeDom.Compiler.GeneratedCode("System.Data.Entity.Design.EntityClassGenerator", "4.0.0.0")] public global::System.Data.Objects.ObjectResult<ArtistSearchVariation> FindSearchVariation(string source) { global::System.Data.Objects.ObjectParameter sourceParameter; if ((source != null)) { sourceParameter = new global::System.Data.Objects.ObjectParameter("Source", source); } else { sourceParameter = new global::System.Data.Objects.ObjectParameter("Source", typeof(string)); } return base.ExecuteFunction<ArtistSearchVariation>("FindSearchVariation", sourceParameter); } But what I would like to do is something like this... public class Repository<E, C> : IRepository<E, C>, IDisposable where E : EntityObject where C : ObjectContext { private readonly C _ctx; // ... public ObjectResult<E> ExecuteFunction(string functionName, params[]) { // Create object parameters return _ctx.ExecuteFunction<E>(functionName, /* parameters */) } } Anyone know why I have to call ExecuteFunction from base instead of _ctx? Also, is there any way to do something like I've written out? I would really like to keep my repository generic, but with having to execute stored procedures it's looking more and more difficult... Thanks, Matt

  • ActiveMq NMS Disconnects after about 30 seconds

    - by Kelly
    'm trying to do simple pub/sub with ActiveMq. I can get it all working fine, but the subscriber disconnects after about 30 seconds. I've looked for a timeout type of value I can change but nothing seems to be working. Here is the subscriber: using System; using Apache.NMS; using Apache.NMS.ActiveMQ; using Apache.NMS.ActiveMQ.Commands; namespace ActiveMQCatcher { internal class Program { private static void Main(string[] args) { IConnectionFactory factory = new ConnectionFactory("tcp://localhost:61616/"); using (IConnection connection = factory.CreateConnection()) { connection.ClientId = "MYID"; connection.Start(); using (ISession session = connection.CreateSession()) { IMessageConsumer consumer = session.CreateConsumer(new ActiveMQTopic("MYTOPIC"), null, false); consumer.Listener += consumer_Listener; Console.ReadLine(); } connection.Stop(); } } private static void consumer_Listener(IMessage message) { Console.WriteLine("Got: " + ((ITextMessage) message).Text); } } } I tried this: connection.RequestTimeout = TimeSpan.MaxValue; But it didn't seem to change anything. To get the problem just run the program and sit waiting for about 30 seconds. You can see the connection disappear in the ActiveMQ Console (http://localhost:8161/admin/connections.jsp by default) Any ideas?

  • How can I mock this asynchronous method?

    - by Charlie
    I have a class that roughly looks like this: public class ViewModel { public ViewModel(IWebService service) { this.WebService = service; } private IWebService WebService{get;set;} private IEnumerable<SomeData> MyData{get;set;} private void GetReferenceData() { this.WebService.BeginGetStaticReferenceData(GetReferenceDataOnComplete, null); } private void GetReferenceDataOnComplete(IAsyncResult result) { this.MyData = this.WebService.EndGetStaticReferenceData(result); } . . . } I want to mock my IWebService interface so that when BeginGetStaticReferenceData is called it is able to call the callback method. I'm using Moq and I can't work out how to do this. My unit test set up code looks something like: //Arrange var service = new Mock<IWebService>(); service.Setup(x => x.BeginGetStaticReferenceData(/*.......don't know.....*/)); service.Setup(x => x.EndGetStaticReferenceData(It.IsAny<IAsyncResult>())).Returns(new List<SomeData>{new SomeData{Name="blah"}}); var viewModel = new ViewModel(service.Object); . .

  • ws-xmlrpc claims error on part of service but other clients work fine

    - by mludd
    I've been trying to connect to an rTorrent instance using ws-xmlrpc and it just isn't going too well. Now, the URL I'm using is the same that I've been using when making sure that rTorrent's XMLRPC support is fine (which it appears to be since both a native OS X application and a small python script I threw together appear to be able to talk to it just fine without any errors). However, when I try using ws-xmlrpc to connect I get org.apache.xmlrpc.XmlRpcException: Failed to create input stream: Unexpected end of file from serverat the top of my stack trace followed by a bunch of steps down to: java.net.SocketException: Unexpected end of file from server at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:769) ... So basically, it seems that ws-xmlrpc is convinced that the reply from rTorrent is malformed somehow but other libraries apparently have no problem with it. The code I use to call rTorrent is: private Object callRTorrent(String command, Object[] params) { Object result = null; try { // xmlrpcclient is an XmlRpcClient object and is instantied in // the class constructor result = xmlrpcclient.execute(command, params); } catch(XmlRpcException xre) { System.out.println("Unable to execute method "+command); xre.printStackTrace(); } return result; } With command set to system.listMethodsand params set to an empty Object[]. From reading documentation and googling my conclusion is that I'm not doing anything obviously wrong and this problem doesn't appear to be common, so does anyone have a clue what's going on here?

  • Visual Studio code metrics misreporting lines of code

    - by Ian Newson
    The code metrics analyser in Visual Studio, as well as the code metrics power tool, report the number of lines of code in the TestMethod method of the following code as 8. At the most, I would expect it to report lines of code as 3. [TestClass] public class UnitTest1 { private void Test(out string str) { str = null; } [TestMethod] public void TestMethod() { var mock = new Mock<UnitTest1>(); string str; mock.Verify(m => m.Test(out str)); } } Can anyone explain why this is the case? Further info After a little more digging I've found that removing the out parameter from the Test method and updating the test code causes LOC to be reported as 2, which I believe is correct. The addition of out causes the jump, so it's not because of braces or attributes. Decompiling the DLL with dotPeek reveals a fair amount of additional code generated because of the out parameter which could be considered 8 LOC, but removing the parameter and decompiling also reveals generated code, which could be considered 5 LOC, so it's not simply a matter of VS counting compiler generated code (which I don't believe it should do anyway).

  • Average function without overflow exception

    - by Ron Klein
    .NET Framework 3.5. I'm trying to calculate the average of some pretty large numbers. For instance: using System; using System.Linq; class Program { static void Main(string[] args) { var items = new long[] { long.MinValue + 100, long.MinValue + 200, long.MinValue + 300 }; try { var avg = items.Average(); Console.WriteLine(avg); } catch (OverflowException ex) { Console.WriteLine("can't calculate that!"); } Console.ReadLine(); } } Obviously, the mathematical result is 9223372036854775607 (long.MaxValue - 200), but I get an exception there. This is because the implementation (on my machine) to the Average extension method, as inspected by .NET Reflector is: public static double Average(this IEnumerable<long> source) { if (source == null) { throw Error.ArgumentNull("source"); } long num = 0L; long num2 = 0L; foreach (long num3 in source) { num += num3; num2 += 1L; } if (num2 <= 0L) { throw Error.NoElements(); } return (((double) num) / ((double) num2)); } I know I can use a BigInt library (yes, I know that it is included in .NET Framework 4.0, but I'm tied to 3.5). But I still wonder if there's a pretty straight forward implementation of calculating the average of integers without an external library. Do you happen to know about such implementation? Thanks!! UPDATE: The previous example, of three large integers, was just an example to illustrate the overflow issue. The question is about calculating an average of any set of numbers which might sum to a large number that exceeds the type's max value. Sorry about this confusion. I also changed the question's title to avoid additional confusion. Thanks all!!

  • MSTest Test Context Exception Handling

    - by Flip
    Is there a way that I can get to the exception that was handled by the MSTest framework using the TestContext or some other method on a base test class? If an unhandled exception occurs in one of my tests, I'd like to spin through all the items in the exception.Data dictionary and display them to the test result to help me figure out why the test failed (we usually add data to the exception to help us debug in the production env, so I'd like to do the same for testing). Note: I am not testing that an exception was SUPPOSED TO HAPPEN (I have other tests for that), I am testing a valid case, I just need to see the exception data. Here is a code example of what I'm talking about. [TestMethod] public void IsFinanceDeadlineDateValid() { var target = new BusinessObject(); SetupBusinessObject(target); //How can I capture this in the text context so I can display all the data //in the exception in the test result... var expected = 100; try { Assert.AreEqual(expected, target.PerformSomeCalculationThatMayDivideByZero()); } catch (Exception ex) { ex.Data.Add("SomethingImportant", "I want to see this in the test result, as its important"); ex.Data.Add("Expected", expected); throw ex; } } I understand there are issues around why I probably shouldn't have such an encapsulating method, but we also have sub tests to test all the functionality of PerformSomeCalculation... However, if the test fails, 99% of the time, I rerun it passes, so I can't debug anything without this information. I would also like to do this on a GLOBAL level, so that if any test fails, I get the information in the test results, as opposed to doing it for each individual test. Here is the code that would put the exception info in the test results. public void AddDataFromExceptionToResults(Exception ex) { StringBuilder whereAmI = new StringBuilder(); var holdException = ex; while (holdException != null) { Console.WriteLine(whereAmI.ToString() + "--" + holdException.Message); foreach (var item in holdException.Data.Keys) { Console.WriteLine(whereAmI.ToString() + "--Data--" + item + ":" + holdException.Data[item]); } holdException = holdException.InnerException; } }

  • AssemblyLoadException in postsharp, problem with arguments from referenced DLLs?

    - by RodH257
    I'm just starting out with postsharp/AOP. I want to make some instrumentation for C# to track the usage of some addins that I write for a peice of software. I am trying to use the OnMethodBoundaryAspect class to take note of the values of some of the parameters when the method is called. Those parameters are types which are referenced in an external DLL. When I add my attribute to the method, the project won't build, I get the following error Error 2 Unhandled exception (2.0.5.1204, 64 bit, CLR 2.0, Release): PostSharp.CodeModel.AssemblyLoadException: Error while loading the assembly "C:\Program Files\Autodesk\Revit Structure 2011\Program\RevitAPI.dll": Could not load file or assembly 'revitapi, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) The REvitAPI.dll is the file with the type in it. I've also tested just adding the attribute to the project but not applying it to any methods, this also causes the error. So it appears its not related to the method parameter types itself, but merely the existence of this DLL. Has anyone come across this issue before, or can anyone point me in the right direction of where to get some more info on this?

  • How to generating comments in hbm2java created POJO?

    - by jschoen
    My current setup using hibernate uses the hibernate.reveng.xml file to generate the various hbm.xml files. Which are then turned into POJOs using hbm2java. We spent some time while designing our schema, to place some pretty decent descriptions on the Tables and there columns. I am able to pull these descriptions into the hbm.xml files when generating them using hbm2jhbmxml. So I get something similar to this: <class name="test.Person" table="PERSONS"> <comment>The comment about the PERSONS table.</comment> <property name="firstName" type="string"> <column name="FIRST_NAME" length="100" not-null="true"> <comment>The first name of this person.</comment> </column> </property> <property name="middleInitial" type="string"> <column name="MIDDLE_INITIAL" length="1"> <comment>The middle initial of this person.</comment> </column> </property> <property name="lastName" type="string"> <column name="LAST_NAME" length="100"> <comment>The last name of this person.</comment> </column> </property> </class> So how do I tell hbm2java to pull and place these comments in the created Java files? I have read over this about editing the freemarker templates to change the way code is generated. I under stand the concept, but it was not to detailed about what else you could do with it beyond there example of pre and post conditions.

  • SDL_image/C++ OpenGL Program: IMG_Load() produces fuzzy images

    - by Kami
    I'm trying to load an image file and use it as a texture for a cube. I'm using SDL_image to do that. I used this image because I've found it in various file formats (tga, tif, jpg, png, bmp) The code : SDL_Surface * texture; //load an image to an SDL surface (i.e. a buffer) texture = IMG_Load("/Users/Foo/Code/xcode/test/lena.bmp"); if(texture == NULL){ printf("bad image\n"); exit(1); } //create an OpenGL texture object glGenTextures(1, &textureObjOpenGLlogo); //select the texture object you need glBindTexture(GL_TEXTURE_2D, textureObjOpenGLlogo); //define the parameters of that texture object //how the texture should wrap in s direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); //how the texture should wrap in t direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); //how the texture lookup should be interpolated when the face is smaller than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); //how the texture lookup should be interpolated when the face is bigger than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); //send the texture image to the graphic card glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, texture->w, texture->h, 0, GL_RGB, GL_UNSIGNED_BYTE, texture-> pixels); //clean the SDL surface SDL_FreeSurface(texture); The code compiles without errors or warnings ! I've tired all the files formats but this always produces that ugly result : I'm using : SDL_image 1.2.9 & SDL 1.2.14 with XCode 3.2 under 10.6.2 Does anyone knows how to fix this ?

  • How to get the stacktrace in a mobile device?

    - by Daniel Moura
    I'm getting a NullPointerException in a Nokia S40. I want to know what is causing this exception. The device shows: NullPointerException java/lang/NullPointerException This error only occurs in the device, running in the emulator the application works fine. I use microlog to debug my application. But the application works fine if the log is enabled. Is there a way to get the stack trace when I get this NullPointerException? I don't need all details like the line number just which method cause this exception. UPDATE: I installed the same application in another Nokia S40 and the same error didn't occur. Nokia 2660 - error Nokia 6131 - no error UPDATE 2: Somehow I find what was causing the NullPointerException. import javax.microedition.lcdui.Canvas; import javax.microedition.lcdui.Graphics; public class OuterClass extends Canvas { private Config config; public OuterClass() { this.config = new Config(); } public void paint(Graphics graphics) { HelperClass helper = new HelperClass(this.config); helper.doStuff(); } public void dispose() { this.config = null; } public class Config implements IConfig { public int getSomething() { // ... } } } public class HelperClass { private IConfig config; public HelperClass(IConfig) { this.config = config; } public doStuff() { config.getSomething(); // Here is thrown NullPointerException } } In some situations a thread is started and call the OuterClass.dispose() before the helper.doStuff() causing the NPE. I think when I enabled the log it made the thread slower and helper.doStuff() was called when I expected it to be called.

  • Not able to use 7-Zip to compress stdin and output with stdout?

    - by acidzombie24
    I get the error "Not implemented". I want to compress a file using 7-Zip via stdin then take the data via stdout and do more conversions with my application. In the man page it shows this example: % echo foo | 7z a dummy -tgzip -si -so /dev/null I am using Windows and C#. Results: 7-Zip 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Creating archive StdOut System error: Not implemented Code: public static byte[] a7zipBuf(byte[] b) { string line; var p = new Process(); line = string.Format("a dummy -t7z -si -so "); p.StartInfo.Arguments = line; p.StartInfo.FileName = @"C:\Program Files\7-Zip\7z.exe"; p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; p.StartInfo.CreateNoWindow = true; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true; p.StartInfo.RedirectStandardInput = true; p.Start(); p.StandardInput.BaseStream.Write(b, 0, b.Length); p.StandardInput.Close(); Console.Write(p.StandardError.ReadToEnd()); //Console.Write(p.StandardOutput.ReadToEnd()); return p.StandardOutput.BaseStream.ReadFully(); } Is there another simple way to read the file into memory? Right now I can 1) write to a temporary file and read (easy and can copy/paste some code) 2) use a file pipe (medium? I have never done it) 3) Something else.

  • Sharing sessions across applications using the ASP.NET Session State Service

    - by Dan
    I am trying to share sessions between two web applications, both hosted on the same server. One is a .net 2.0 web forms application the other is as .net 3.5 MVC2 application. Both apps have their session set up like this: <sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:42424" /> In the webform application I am posting the the session key to the MVC app: protected void LinkButton1_Click(object sender, EventArgs e) { Session["myvariable"] = "dan"; string sessionKey = HttpContext.Current.Session.SessionID; //Followed by some code that posts sessionKey to the other application } I then recieve it in the MVC application and try use the same session like this: [HttpPost] public void Recieve(string sessionKey ) { var manager = new SessionIDManager(); bool redirected; bool IsAdded; manager.SaveSessionID(HttpContext.ApplicationInstance.Context, Id, out redirected, out IsAdded); var sessionKey = Session["myvariable"]; } The key is being posted but the session does not seem to get loaded in the MVC app, i.e. sessionKey is null. Can what I am trying to do be done?

  • Is there a better way to create a generic convert string to enum method or enum extension?

    - by Kelsey
    I have the following methods in an enum helper class (I have simplified it for the purpose of the question): static class EnumHelper { public enum EnumType1 : int { Unknown = 0, Yes = 1, No = 2 } public enum EnumType2 : int { Unknown = 0, Dog = 1, Cat = 2, Bird = 3 } public enum EnumType3 : int { Unknown = 0, iPhone = 1, Andriod = 2, WindowsPhone7 = 3, Palm = 4 } public static EnumType1 ConvertToEnumType1(string value) { return (string.IsNullOrEmpty(value)) ? EnumType1.Unknown : (EnumType1)(Enum.Parse(typeof(EnumType1), value, true)); } public static EnumType2 ConvertToEnumType2(string value) { return (string.IsNullOrEmpty(value)) ? EnumType2.Unknown : (EnumType2)(Enum.Parse(typeof(EnumType2), value, true)); } public static EnumType3 ConvertToEnumType3(string value) { return (string.IsNullOrEmpty(value)) ? EnumType3.Unknown : (EnumType3)(Enum.Parse(typeof(EnumType3), value, true)); } } So the question here is, can I trim this down to an Enum extension method or maybe some type of single method that can handle any type. I have found some examples to do so with basic enums but the difference in my example is all the enums have the Unknown item that I need returned if the string is null or empty (if no match is found I want it to fail). Looking for something like the following maybe: EnumType1 value = EnumType1.Convert("Yes"); // or EnumType1 value = EnumHelper.Convert(EnumType1, "Yes"); One function to do it all... how to handle the Unknown element is the part that I am hung up on.
