  • Error when compiling c# project in VS2012 when using Postsharp

    - by Thewads
    I am currently working on a project where we were wanting to add PostSharp functionality. I have set up my Postsharp attribute as so [Serializable] public class NLogTraceAttribute : OnMethodBoundaryAspect { private readonly string _logLevel; ILogger logger; public NLogTraceAttribute(string logLevel) { _logLevel = logLevel; logger = new Logger("TraceAttribute"); } public override void OnEntry(MethodExecutionArgs args) { LogAction("Enter", args); } public override void OnExit(MethodExecutionArgs args) { LogAction("Leave", args); } private void LogAction(string action, MethodExecutionArgs args) { var argumentsInfo = args.GetArgumentsInfo(); logger.Log(_logLevel, "{0}: {1}.{2}{3}", action, args.Method.DeclaringType.Name, args.Method.Name, argumentsInfo); } } and trying to use it as [NLogTrace(NLogLevel.Debug)] However when compiling the project I am getting the following error: Error 26 Cannot serialize the aspects: Type 'NLog.Logger' in Assembly 'NLog, Version=2.0.0.0, Culture=neutral, PublicKeyToken=5120e14c03d0593c' is not marked as serializable.. Any help would be appreciated

  • using extends with Java Generics

    - by Sandro
    Lets say that I have the following code: public class Shelter<A extends Animal, B extends Animal> { List<A> topFloor = new Vector<A>(); List<B> bottomFloor = new Vector<B>(); public A getFirstTopFloorAnimal(){return topFloor.firstElement();} public B getFirstBottomFloorAnimal(){return bottomFloor.firstElement();} //This compiles but when I try to use it, it only returns objects public List<Animal> getAnimals() { Vector a = new Vector(topFloor); a.addAll(bottomFloor); return a; } } Now for somereason the following code compiles. But when I try to use getAnimals() I get a of objects instead of Animal. Any ideas why this is? Does this have to do with the List is NOT a List idea in the Generics tutorial? Thank you.

  • case insensitive mapping for Spring MVC @RequestMapping annotations

    - by Zahid Riaz
    I have Controller having multiple @RequestMapping annotations in it. @Controller public class SignUpController { @RequestMapping("signup") public String showSignUp() throws Exception { return "somejsp"; } @RequestMapping("fullSignup") public String showFullSignUp() throws Exception { return "anotherjsp"; } @RequestMapping("signup/createAccount") public String createAccount() throws Exception { return "anyjsp"; } } How can I map these @RequestMapping to case insensitive. i.e. if I use "/fullsignup" or "/fullSignup" I should get "anotherjsp". But this is not happening right now. Only "/fullSignup" is working fine.

  • Is it safe to access asp.net session variables through static properties of a static object?

    - by Ronnie Overby
    Is it safe to access asp.net session variables through static properties of a static object? Here is what I mean: public static class SessionHelper { public static int Age { get { return (int)HttpContext.Current.Session["Age"]; } set { HttpContext.Current.Session["Age"] = value; } } public static string Name { get { return (string)HttpContext.Current.Session["Name"]; } set { HttpContext.Current.Session["Name"] = value; } } } Is it possible that userA could access userB's session data this way?

  • SelectList in Asp-mvc and data from the database

    - by George
    Hello guys. I'm having some troubles with SelectList in ASP.MVC. Here is the issue: I have a Create View and begind a ViewModel model. The page load just fine (GET verb). But when posting, something happens, and my model is considered invalid, and it cannot insert. Here's what i've tried so far. public class DefinitionFormViewModel { private Repository<Category> categoryRepository = new Repository<Category>(); public Definition ViewDefinition { get; private set; } public SelectList Categories { get; private set; } public DefinitionFormViewModel(Definition def) { ViewDefinition = def; // here i wanted to place it directly, like shown in NerdDinner Tutorial // new SelectList(categoryRepository.All(),ViewDefinition.Category); Categories = new SelectList(categoryRepository.All(), "CategoryId", "CategoryName", ViewDefinition.CategoryId); } } // pageview which inherits DefinitionFormViewModel <div class=editor-field"> <%= Html.DropDownList("Category",Model.Categories) %> <%= Html.ValidationMessageFor(model => Model.ViewDefinition.Category) %> </div> // controller methods [Authorize] public ActionResult Create() { Definition definition = new Definition(); return View(new DefinitionFormViewModel(definition)); } [AcceptVerbs(HttpVerbs.Post), Authorize] public ActionResult Create(int id,Definition definition) { Term term = termRepository.SingleOrDefault(t => t.TermId == id); if (term == null) { return View("NotFound", new NotFoundModel("Termo não encontrado", "Termo não encontrado", "Nos desculpe, mas não conseguimos encontrar o termo solicitado.", "Indíce de Termos", "Index", "Term")); } else { if (ModelState.IsValid) { try { definition.TermId = term.TermId; definition.ResponsibleUser = User.Identity.Name; UpdateModel(definition); term.Definitions.Add(definition); termRepository.SaveAll(); return RedirectToAction("Details", "Term", new { id = term.TermId }); } catch (System.Data.SqlClient.SqlException sqlEx) { ModelState.AddModelError("DatabaseError", "Houve um erro na inserção desta nova definição"); } catch { foreach (RuleViolation rv in definition.GetRuleViolations()) { ModelState.AddModelError(rv.PropertyName, rv.ErrorMessage); } } } } return View(new DefinitionFormViewModel(definition)); } I'm sorry about the long post, but I cant figure this out. I got no graphic errors or exceptions. My execution terminates in if (ModelState.IsValid). Thanks for your time George

As follow: public class EccUDFLogLoader extends LoadFunc { @Override public InputFormat getInputFormat() { System.out.println("I am in getInputFormat function"); return new MyInputFormat(); } } public class MyInputFormat extends TextInputFormat { public RecordReader createRecordReader(InputSplit inputSplit, JobConf jobConf) throws IOException { System.out.prinln("I am in createRecordReader"); //MyRecordReader suppose to handle record boundary return new MyRecordReader((FileSplit)inputSplit, jobConf); } } For each mapper, it print out I am in getInputFormat function but not I am in createRecordReader. I am wondering if anyone can provide a hint on how to hoop up my costome MyInputFormat to PIG's UDF loader? Much Thanks. I am using PIG on Amazon EMR.

  • Good way to maintain Muliple level selection menu list in J2ME

    - by geoaxis
    Hello, I need a good way to maintain multiple form level data for menue selection. So for example If I have A and B, each might Have 1 2 3 so A A1 A2 A3 B B1 B2 B3 And this can continue for long, so that I could have A - A1 - A1.1 - A1.1.1 -.... I have the following class in place, works ok But I suspect we could have better. I just need to perform selection ni a selection tree like Widget, but each level of selection comes in another form (in J2ME) import java.util.Vector; public class Tag { private String tag; private Vector childTags; private Tag parent; Tag(String tag, Vector childtag) { this.tag = tag; this.childTags= childTags; } public void setChildTags(Vector childTags) { this.childTags = childTags; } public Vector getChildTags() { return this.childTags; } public String getTag() { return this.tag; } public String toString(int depth) { String a =""; if(depth==0) { a = a + this.getTag(); } if(this.getChildTags()!= null) { for(int k=0;k <this.getChildTags().capacity(); k++) { for (int i=0; i<depth; i++ ) { a = a + ("-"); } a = a+ ( ((Tag)this.getChildTags().elementAt(k)).toString(depth++)); } } return a; } }

  • Am I abusing Policies?

    - by pmr
    I find myself using policies a lot in my code and usually I'm very happy with that. But from time to time I find myself confronted with using that pattern in situations where the Policies are selected and runtime and I have developed habbits to work around such situations. Usually I start with something like that: class DrawArrays { protected: void sendDraw() const; }; class DrawElements { protected: void sendDraw() const; }; template<class Policy> class Vertices : public Policy { using Policy::sendDraw(); public: void render() const; }; When the policy is picked at runtime I have different choices of working around the situation. Different code paths: if(drawElements) { Vertices<DrawElements> vertices; } else { Vertices<DrawArrays> vertices; } Inheritance and virtual calls: class PureVertices { public: void render()=0; }; template<class Policy> class Vertices : public PureVertices, public Policy { //.. }; Both solutions feel wrong to me. The first creates an umaintainable mess and the second introduces the overhead of virtual calls that I tried to avoid by using policies in the first place. Am I missing the proper solutions or do I use the wrong pattern to solve the problem?

  • wrapping aspx user controls commands in a transaction

    - by Hans Gruber
    I'm working on heavily dynamic and configurable CMS system. Therefore, many pages are composed of a dynamically loaded set of user controls. To enable loose coupling between containers (pages) and children (user controls), all user controls are responsible for their own persistence. Each User Control is wired up to its data/service layer dependencies via IoC. They also implement an IPersistable interface, which allows the container .aspx page to issue a Save command to its children without knowledge of the number or exact nature of these user controls. Note: what follows is only pseudo-code: public class MyUserControl : IPersistable, IValidatable { public void Save() { throw new NotImplementedException(); } public bool IsValid() { throw new NotImplementedException(); } } public partial class MyPage { public void btnSave_Click(object sender, EventArgs e) { foreach (IValidatable control in Controls) { if (!control.IsValid) { throw new Exception("error"); } } foreach (IPersistable control in Controls) { if (!control.Save) { throw new Exception("error"); } } } } I'm thinking of using declarative transactions from the System.EnterpriseService namespace to wrap the btnSave_Click in a transaction in case of an exception, but I'm not sure how this might be achieved or any pitfalls to such an approach.

  • Rhino Mocks Partial Mock

    - by dotnet crazy kid
    I am trying to test the logic from some existing classes. It is not possible to re-factor the classes at present as they are very complex and in production. What I want to do is create a mock object and test a method that internally calls another method that is very hard to mock. So I want to just set a behaviour for the secondary method call. But when I setup the behaviour for the method, the code of the method is invoked and fails. Am I missing something or is this just not possible to test without re-factoring the class? I have tried all the different mock types (Strick,Stub,Dynamic,Partial ect.) but they all end up calling the method when I try to set up the behaviour. using System; using MbUnit.Framework; using Rhino.Mocks; namespace MMBusinessObjects.Tests { [TestFixture] public class PartialMockExampleFixture { [Test] public void Simple_Partial_Mock_Test() { const string param = "anything"; //setup mocks MockRepository mocks = new MockRepository(); var mockTestClass = mocks.StrictMock<TestClass>(); //record beahviour *** actualy call into the real method stub *** Expect.Call(mockTestClass.MethodToMock(param)).Return(true); //never get to here mocks.ReplayAll(); //this is what i want to test Assert.IsTrue(mockTestClass.MethodIWantToTest(param)); } public class TestClass { public bool MethodToMock(string param) { //some logic that is very hard to mock throw new NotImplementedException(); } public bool MethodIWantToTest(string param) { //this method calls the if( MethodToMock(param) ) { //some logic i want to test } return true; } } } }

  • new Statefull session bean instance without calling lookup

    - by kislo_metal
    Hi! Scenario: I have @Singleton UserFactory (@Stateless could be) , it`s method createSession() generating @Statefull UserSession bean by manual lookup. If I am injecting by DI @EJB - i will get same instance during calling fromFactory() method(as it should be) What I want - is to get new instance of UserSession without preforming lookup. Q1: how could I call new instance of @Statefull session bean? Code: @Singleton @Startup @LocalBean public class UserFactory { @EJB private UserSession session; public UserFactory() { } @Schedule(second = "*/1", minute = "*", hour = "*") public void creatingInstances(){ try { InitialContext ctx = new InitialContext(); UserSession session2 = (UserSession) ctx.lookup("java:global/inferno/lic/UserSession"); System.out.println("in singleton UUID " +session2.getSessionUUID()); } catch (NamingException e) { e.printStackTrace(); } } @Schedule(second = "*/1", minute = "*", hour = "*") public void fromFactory(){ System.out.println("in singleton UUID " +session.getSessionUUID()); } public UserSession creatSession(){ UserSession session2 = null; try { InitialContext ctx = new InitialContext(); session2 = (UserSession) ctx.lookup("java:global/inferno/lic/UserSession"); System.out.println("in singleton UUID " +session2.getSessionUUID()); } catch (NamingException e) { e.printStackTrace(); } return session2; } } As I understand, calling of session.getClass().newInstance(); is not a best idea Q2 : is it true? I am using glassfish v3, ejb 3.1.

  • Is it ok to dynamic cast "this" as a return value?

    - by Panayiotis Karabassis
    This is more of a design question. I have a template class, and I want to add extra methods to it depending on the template type. To practice the DRY principle, I have come up with this pattern (definitions intentionally omitted): template <class T> class BaseVector: public boost::array<T, 3> { protected: BaseVector<T>(const T x, const T y, const T z); public: bool operator == (const Vector<T> &other) const; Vector<T> operator + (const Vector<T> &other) const; Vector<T> operator - (const Vector<T> &other) const; Vector<T> &operator += (const Vector<T> &other) { (*this)[0] += other[0]; (*this)[1] += other[1]; (*this)[2] += other[2]; return *dynamic_cast<Vector<T> * const>(this); } } template <class T> class Vector : public BaseVector<T> { public: Vector<T>(const T x, const T y, const T z) : BaseVector<T>(x, y, z) { } }; template <> class Vector<double> : public BaseVector<double> { public: Vector<double>(const double x, const double y, const double z); Vector<double>(const Vector<int> &other); double norm() const; }; I intend BaseVector to be nothing more than an implementation detail. This works, but I am concerned about operator+=. My question is: is the dynamic cast of the this pointer a code smell? Is there a better way to achieve what I am trying to do (avoid code duplication, and unnecessary casts in the user code)? Or am I safe since, the BaseVector constructor is private?

  • Relative Paths in .htaccess, how to attach to a variable?

    - by devians
    I have a very heavy htaccess mod_rewrite file that runs my application. As we sometimes take over legacy websites, I sometimes need to support old urls to old files, where my application processes everything post htaccess. My ultimate goal is to have a 'Demilitarized Zone' for old file structures, and use mod rewrite to check for existence there before pushing to the application. This is pretty easy to do with files, by using: RewriteCond %{IS_SUBREQ} true RewriteRule .* - [L] RewriteCond %{ENV:REDIRECT_STATUS} 200 RewriteRule .* - [L] RewriteCond Public/DMZ/$1 -F [OR] RewriteRule ^(.*)$ Public/DMZ/$1 [QSA,L] This allows pseudo support for relative urls by not hardcoding my base path (I cant assume I will ever be deployed in document root) anywhere and using subrequests to check for file existence. Works fine if you know the file name, ie http://domain.com/path/to/app/legacyfolder/index.html However, my legacy urls are typically http://domain.com/path/to/app/legacyfolder/ Mod_Rewrite will allow me to check for this by using -d, but it needs the complete path to the directory, ie RewriteCond Public/DMZ/$1 -F [OR] RewriteCond /var/www/path/to/app/Public/DMZ/$1 -d RewriteRule ^(.*)$ Public/DMZ/$1 [QSA,L] I want to avoid the hardcoded base path. I can see one possible solutions here, somehow determining my path and attaching it to a variable [E=name:var] and using it in the condition. Any implementation that allows me to existence check a directory is more than welcome.

  • Problem with UserControl with custom Dependency Property

    - by Mathias Koch
    Hi, I'm writing a user control with a dependency property for a search text called SearchText. It is a dependency property because I want to allow consumers of the control to use data binding. The user control contains a WPF TextBox where the user can enter the search text. I could use data binding to connect the SearchText dependency property of the user control with the Text dependency property of the TextBox, but this binding only fires when the text box looses input focus. What I want is SearchText to be updated after every change of Text. So I have added a TextChanged event handler to the user control where I set SearchText to the value of Text. My Problem is, the SearchText binding doesn't work, the source never gets updated. What am I doing wrong? Here's the relevant part of the user controls code-behind: public partial class UserControlSearchTextBox : UserControl { public string SearchText { get { return (string)GetValue(SearchTextProperty); } set { SetValue(SearchTextProperty, value); } } public static readonly DependencyProperty SearchTextProperty = DependencyProperty.Register("SearchText", typeof(string), typeof(UserControlSearchTextBox), new UIPropertyMetadata("")); private void TextBox_TextChanged(object sender, TextChangedEventArgs e) { SearchText = ((TextBox)sender).Text; } ... } The window that contains an instance of the user control has its DataContext set to an object that has a property also called SearchText. <uc:UserControlSearchTextBox SearchText="{Binding SearchText}" /> The data context of the Window: public class DataSourceUserManual : DataSourceBase { private string _searchText; public string SearchText { get { return _searchText; } set { _searchText = value; ... OnPropertyChanged("SearchText"); } } } Unfortunately, this setter is not called when I type into the text box. Any ideas?

  • vsts load testing wcf app

    - by ashish.s
    I have a simple test written like this public class Test { [ThreadStatic] private static ServiceClient client; [TestMethod] public void TestCase1() { If( client == null) { .... //instantiate client } client.CallMyServiceMethod() } [TestMethod] public void TestCase2() { using(var newClient = new ServiceClient()) { newClient.CallMyServiceMethod() } } The percentage of new users is set to 100 % for the test, and the user load is constant load of 1. But the response time for TestCase1 is about 3 times better than TestCase2. Can someone see what i am missing here ? many thanks

  • How can I map stored procedure result into a custom class with linq-to-sql?

    - by Remnant
    I have a stored procedure that returns a result set (4 columns x n Rows). The data is based on multiple tables within my database and provides a summary for each department within a corporate. Here is sample: usp_GetDepartmentSummary DeptName EmployeeCount Male Female HR 12 5 7 etc... I am using linq-to-sql to retrieve data from my database (nb - have to use sproc as it is something I have inherited). I would like to call the above sproc and map into a department class: public class Department { public string DeptName {get; set;} public int EmployeeCount {get; set;} public int MaleCount {get; set;} public int FemaleCount {get; set;} } In VS2008, I can drag and drop my sproc onto the methods pane of the linq-to-sql designer. When I examine the designer.cs the return type for this sproc is defined as: ISingleResult<usp_GetDepartmentSummaryResult> What I would like to do is amend this somehow so that it returns a Department type so that I can pass the results of the sproc as a strongly typed view: <% foreach (var dept in Model) { %> <ul> <li class="deptname"><%= dept.DeptName %></li> <li class="deptname"><%= dept.EmployeeCount %></li> etc... Any ideas how to achieve this? NB - I have tried amending the designer.cs and dbml xml file directly but with limited success. I admit to being a little out of my depth when it comes to updating those files directly and I am not sure it is best practice? Would be good to get some diretion. Thanks much
