  • Is there a way to unit test an async method?

    - by Jiho Han
    I am using Xunit and NMock on .NET platform. I am testing a presentation model where a method is asynchronous. The method creates an async task and executes it so the method returns immediately and the state I need to check aren't ready yet. I can set a flag upon finish without modifying the SUT but that would mean I would have to keep checking the flag in a while loop for example, with perhaps timeout. What are my options?

  • String generation with regex criteria

    - by menjaraz
    I wonder wether it is feasible to implement an optimal string generator Class meeting the following requirements: Generation criteria using regex Lexicographical order enumeration. Count propetry Indexed access I don't feel comfortable with regular expression: I cannot come up with a starting piece of code but I just think of a naive implementation using a TList as a base class and use a filter (Regex) against "brute force" generated string. Thank you.

  • Add a build number to TFS 2010

    - by Vaccano
    I have a lot of legacy Delphi 5 & 6 Code. We want to test this code using the new Microsoft Test Manager (part of VS2010) To effectively track your testing using this tool you need to use build numbers. To get Delphi 5 or 6 building in TFS Build 2010 is a huge task. One that I am not sure I want to take on. Is there a way I can just insert my build numbers in to tfs?

  • How do I get the entity framework to work with archive flags?

    - by Orion Adrian
    I'm trying to create a set of tables where we don't actually delete them, but rather we set the archive flags instead. When we delete an entity, it shouldn't be deleted, it should be marked as archived instead. What are the programming patterns to support this? I would also prefer not to have to roll out my own stored procs for every table that have these archive flags if there is another solution.

  • which collaborative tools do you use to communicate between team members [closed]

    - by john
    I work for a small company and would like to set up some sort of a collaborative tool so that team members can share thoughts, upload documents...something like sharepoint maybe, but not that suffisticated. Only good option I've seen so far is joomla CMS. Just want to get an opinion of the community on which tools they have used for these purposes. I know this is not programming related but I thought stackoverflow community would be good to get an opinion on this.

  • Is the board game "Go" NP complete?

    - by sharkin
    There are plenty of Chess AI's around, and evidently some are good enough to beat some of the world's greatest players. I've heard that many attempts have been made to write successful AI's for the board game Go, but so far nothing has been conceived beyond average amateur level. Could it be that the task of mathematically calculating the optimal move at any given time in Go is an NP-complete problem?

  • Action Item shown only in Landscape?

    - by roboguy12
    I was just wondering if it were at all possible for an Action Bar icon to only be shown when the device is in landscape mode? In portrait I have an onscreen button for a certain task, but in order to take advantage of all of the screen-space in landscape, that button won't fit. So I was wondering if I could put it in the Action Bar, but it would only be necessary when the device is in landscape. Thanks!

  • WCF Self Host Service - Endpoints in C#

    - by Kyle
    My first few attempts at creating a self hosted service. Trying to make something up which will accept a query string and return some text but have have a few issues: All the documentation talks about endpoints being created automatically for each base address if they are not found in a config file. This doesn't seem to be the case for me, I get the "Service has zero application endpoints..." exception. Manually specifying a base endpoint as below seems to resolve this: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; using System.ServiceModel.Description; namespace TestService { [ServiceContract] public interface IHelloWorldService { [OperationContract] string SayHello(string name); } public class HelloWorldService : IHelloWorldService { public string SayHello(string name) { return string.Format("Hello, {0}", name); } } class Program { static void Main(string[] args) { string baseaddr = "http://localhost:8080/HelloWorldService/"; Uri baseAddress = new Uri(baseaddr); // Create the ServiceHost. using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress)) { // Enable metadata publishing. ServiceMetadataBehavior smb = new ServiceMetadataBehavior(); smb.HttpGetEnabled = true; smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15; host.Description.Behaviors.Add(smb); host.AddServiceEndpoint(typeof(IHelloWorldService), new BasicHttpBinding(), baseaddr + "SayHello"); //for some reason a default endpoint does not get created here host.Open(); Console.WriteLine("The service is ready at {0}", baseAddress); Console.WriteLine("Press to stop the service."); Console.ReadLine(); // Close the ServiceHost. host.Close(); } } } } I still think I'm doing something wrong as I don't get the normal "This is a web service...etc..." page when I load up the url How would I go about setting this up to return the value of name in SayHello(string name) when requested thusly: localhost:8080/HelloWorldService/SayHello?name=kyle Do I have to create an endpoing for the SayHello contract as well? I'm trying to walk before running, but this just seems like crawling...Service has zero application endpoints...

  • will_paginate with named_scopes

    - by Lowgain
    I'm using will_paginate for pagination, which has been working well so far, except for this one thing. If I try to paginate a scope, for instance class User < ActiveRecord::Base named_scope :scope, lambda { etc } end User.scope.paginate({:page => params[:page], :per_page => 10}) That will tell me paginate is an undefined method. I'd rather not have to use a second solution for only this scope, is there something I can do here?

  • Xsd recursion of complexTypes

    - by Hatch
    I am just learning XML/XSD and am struggling with the implementation of an XML-schema which models a folder structure. What I had in mind was defining a complexType for the folder which can have additional folder instances that represent subfolders. Using the xsd schema validator here always returns that the schema is invalid. I tried defining the complexType up front and then using the ref keyword for subfolders: <xs:complexType name="tFolder"> <xs:sequence> <xs:element name="Path" type="tFolderType" msdata:Ordinal="0" /> <xs:element ref="Folder" minOccurs="0" maxOccurs="unbounded" /> <xs:element name="File" nillable="true" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:simpleContent msdata:ColumnName="File_Text" msdata:Ordinal="0"> <xs:extension base="xs:string"> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> </xs:sequence> <xs:attribute name="Type" type="tFolderType" /> As for the element itself: <xs:element name="Folder" type="tFolder" /> The error returned by the validator is: "Cannot resolve the name 'Folder' to a(n) 'element declaration' component." and the error occurs at the line <xs:element ref="Folder" minOccurs="0" maxOccurs="unbounded" /\> Defining the complexType within the element itself yields the exact same error: <xs:element name="Folder"> <xs:complexType> <xs:sequence> <xs:element name="Path" type="tFolderType" msdata:Ordinal="0" /> <xs:element ref="Folder" minOccurs="0" maxOccurs="unbounded" /> <xs:element name="File" nillable="true" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:simpleContent msdata:ColumnName="File_Text" msdata:Ordinal="0"> <xs:extension base="xs:string"> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> </xs:sequence> <xs:attribute name="Type" type="tFolderType" /> </xs:complexType> </xs:element> What I've read, this kind of recursion should work using ref. Can anyone tell me what I've done wrong? Maybe the xsd validator is just faulty? If so, does anyone know a better alternative? I've tried using the one from w3.org as well, but it seems to be taken offline...

  • Schema qualified tables with SQLAlchemy, SQLite and Postgresql?

    - by Chris Reid
    I have a Pylons project and a SQLAlchemy model that implements schema qualified tables: class Hockey(Base): __tablename__ = "hockey" __table_args__ = {'schema':'winter'} hockey_id = sa.Column(sa.types.Integer, sa.Sequence('score_id_seq', optional=True), primary_key=True) baseball_id = sa.Column(sa.types.Integer, sa.ForeignKey('summer.baseball.baseball_id')) This code works great with Postgresql but fails when using SQLite on table and foreign key names (due to SQLite's lack of schema support) sqlalchemy.exc.OperationalError: (OperationalError) unknown database "winter" 'PRAGMA "winter".table_info("hockey")' () I'd like to continue using SQLite for dev and testing. Is there a way of have this fail gracefully on SQLite?

    In my base.html file, I am using {% if user.is_authenticated %} <a href="#">{{user.username}}</a> {% else %} <a href="/acc/login/">log in</a> Here, even if the user is logged in, the log in button shows up. Now when I click on the log in link, it shows the username and also the normal login view, saying user is logged in. So, what's wrong?

  • SonarJ like tool for .NET

    - by J. Random Coder
    I'm looking for a tool like SonarJ but for .NET instead of Java. SonarJ helps you to find deviations between he architecture and the code within minutes. It can be integrated into your IDE to help you avoid the introduction of new architetural violations to your code base. You can also use it to maintain metric based software quality rules which will keep complexity under control. I googled and searched SO without satisfying results.

  • Can one Python project use both 2.x and 3.x code?

    - by Begbie00
    Hi all - I'm going to start on a long (~1-year) programming project in Python. I want to use wxPython for my GUI (supports 2.6), but I also want to use 3.1 for the rest of the project (to start using the 3.x syntax). Is there any way for me to design a project that mixes 2.x and 3.x modules? Or should I just bite the bullet and use either 2.x (preferred, since I really want to learn wxPython) or 3.x throughout? Thanks, Mike

  • Evaluating software estimates: sure signs of unrealistic figures?

    - by Totophil
    Whilst answering “Dealing with awful estimates” posted by Ash I shared a few tips that I learned and personally use to spot weak estimates. But I am certain there must be many more! What heuristics to use in the scenario when one needs to make a quick evaluation of software project estimate that has been compiled by a third-party (a colleague, a business partner or an external company)? What are the obvious and not so obvious signs of weak software estimates that can be spotted without much detailed knowledge of task at hand?
