  • NHibernate Tutorial Run-Time Error: HibernateException

  • Sunspot_Rails Rake Aborted When Running Reindex

    - by Walter Chen
    I'm getting the following output after running rake sunspot:reindex. I'm a novice at Rails. I want to add sunspot_rails to my project to add search functionality (with the hope of deploying the project with Heroku). I'm using Rails 3. I followed the instructions here: https://github.com/outoftime/sunspot/blob/master/sunspot_rails/README.rdoc. My various other attempts to diagnose the problem included: installing sunspot in addition to sunspot_rails. I ended up with sunspot_rails v. 1.2.0 and 1.2.1 so I uninstalled 1.2.1 because I have sunspot_rails 1.2.0. installed the nokogiri gem which I understand is a dependency for sunspot_rails. installed libxml2 separately following the instructions here to install nokogiri: http://www.engineyard.com/blog/2010/getting-started-with-nokogiri/ ** Invoke sunspot:reindex (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute sunspot:reindex rake aborted! undefined local variable or method counter' for [removed pound]<Class:0x10359aef8> /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/base.rb:1008:inmethod_missing' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/searchable.rb:235:in solr_index' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/relation/batches.rb:71:infind_in_batches' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/base.rb:440:in __send__' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/base.rb:440:infind_in_batches' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/searchable.rb:234:in solr_index' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/searchable.rb:184:insolr_reindex' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/tasks.rb:57 /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/tasks.rb:56:in each' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/tasks.rb:56 /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:636:incall' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:636:in execute' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:631:ineach' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:631:in execute' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:597:ininvoke_with_call_chain' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/monitor.rb:242:in synchronize' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:590:ininvoke_with_call_chain' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:583:in invoke' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2051:ininvoke_task' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in top_level' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:ineach' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in top_level' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:instandard_exception_handling' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2023:in top_level' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2001:inrun' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:in standard_exception_handling' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:1998:inrun' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/bin/rake:31 /usr/bin/rake:19:in `load' /usr/bin/rake:19 This is what I have in class I'd like to search: searchable do text :fname text :mname text :lname, :default_boost => 2 end Any help would be greatly appreciated!

  • AD-DirectoryServices: .NET2.0 - Speaking architecture, approach and best practices... Suggestions?

    - by Will Marcouiller
    I've been mandated to write an application to migrate the Active Directory access models to another environment. Here's the context: I'm stuck with VB.NET 2005 and .NET Framework 2.0; The application must use the Windows authenticated user to manage AD; The objects I have to handle are Groups, Users and OrganizationalUnits; I intend to use the Façade design pattern to provider ease of use and a fully reusable code; I plan to write a factory for each of the objects managed (group, ou, user); The use of Attributes should be useful here, I guess; As everything is about the DirectoryEntry class when accessing the AD, it seems a good candidate for generic types. Obligatory features: User creates new OUs manually; User creates new group manually; User creates new user (these users are services accounts) manually; Application reads an XML file which contains the OUs, groups and users to create; Application informs the user about the OUs, groups and users that shall be created; User specifies the domain environment where to migrate the XML input file designated objects; User makes changes if needed, and launches the task operations; Application performs required by the XML input file operations against the underlying AD as specified by the user; Application informs the user upon completion. Linear features: User fetches OUs, groups, users; User changes OUs, groups, users; User deletes OUs, groups, users; The application logs AD entries and operations performed, plus errors and exceptions; Nice-to-have features: Application rollbacks operations on error or exception. I've been working for weeks now to get acquainted with the AD and the System.DirectoryServices assembly. But I don't seem to find a way to be fully satisfied with what I'm doing and always looking for better. I have studied Bret de Smet's Linq to AD on CodePlex, but then again, I can't use it as I'm stuck with .NET 2.0, so no Linq! But I've learned about Attributes, and seen that he's working with generic types as he codes a DirectorySource class to perform the operations for OUs, groups and users. I have been able to add groups to the AD; I have been able to add users to the AD; The created user is automatically disabled? I seem to get confused with the use of a LDAP path to add objects. For instance, one needs two instances of a System.DirectoryServices.DirectoryEntry class to add a group, for instance. Why this? Any suggestions? Thanks for any help, code sample, ideas, architural solution, everything!

  • Nice, clean, simple way of getting a dataset from ASP.NET to plain HTML jQuery or JavaScript library

    - by David S
    I know this is a probable open ended question, and I have tried looking around so much over the last year or two... maybe I am looking for a perfect place that doesn't exist! of course it's all about perception no less.. Anyway, just to clarify what I am trying to do and why: I want to be able to use (primarily for the moment) ASP.NET or services thereof to get a dataset - whatever the source data, I can obviously get a dataset of rows/Columns. I want to be able to, as simply as possible, get that data over to the client via xml/json/whatever, to then use in a "variety" of ways. "Variety" of ways meaning I would like to "easily" bind that data to say a grid, or a combo dropdown or just simply render to a textbox - BUT by referencing the dataset as I would say on the serverside. Now I know this all sounds simplistic, and I know there are lots of complications.. so I have tried the following so far over the last year or so: ExtJS - very good, nice solid framework, but just found it a bit too much to use in everyday basic apps - great if I was building a whole application with it Yahoo YUI - not looked recently, but I guess some of the concepts with ExtJS were similar? JQuery - of course to get data etc, it was ok, and I guess there are so many 3rd party plugins, that a mix and match might work? Adobe SPRY - ironically this was as close to getting a dataset style structure to Javascript/client, although it seemed to drop off/go quiet..? I maybe wrong.. I did have a very cursory play with Tibco GI and another one I cannot remember the name of! but again, it felt like it was great to build a whole app perhaps? Anyway, I am very amazed by all of the technologies coming out, and really not biased one way or the other, I really just want a very simple way of getting data from the server, and having a basic/very flexible way of working with that data in the client without using server technologies.. I need to keep the server flexible as I may need to use PHP, or java technologies not just .NET So again, sorry for the rambles, but if anyone out there has had a simple experience, or would like to share some ideas, it would be very welcomed!! David.

  • iPhone reachability checking

    - by Sneakyness
    I've found several examples of code to do what I want (check for reachability), but none of it seems to be exact enough to be of use to me. I can't figure out why this doesn't want to play nice. I have the reachability.h/m in my project, I'm doing #import <SystemConfiguration/SystemConfiguration.h> And I have the framework added. I also have: #import "Reachability.h" at the top of the .m in which I'm trying to use the reachability. Reachability* reachability = [Reachability sharedReachability]; [reachability setHostName:@"http://www.google.com"]; // set your host name here NetworkStatus remoteHostStatus = [reachability remoteHostStatus]; if(remoteHostStatus == NotReachable) {NSLog(@"no");} else if (remoteHostStatus == ReachableViaWiFiNetwork) {NSLog(@"wifi"); } else if (remoteHostStatus == ReachableViaCarrierDataNetwork) {NSLog(@"cell"); } This is giving me all sorts of problems. What am I doing wrong? I'm an alright coder, I just have a hard time when it comes time to figure out what needs to be put where to enable what I want to do, regardless if I want to know what I want to do or not. (So frustrating) Update: This is what's going on. This is in my viewcontroller, which I have the #import <SystemConfiguration/SystemConfiguration.h> and #import "Reachability.h" set up with. This is my least favorite part of programming by far. FWIW, we never ended up implementing this in our code. The two features that required internet access (entering the sweepstakes, and buying the dvd), were not main features. Nothing else required internet access. Instead of adding more code, we just set the background of both internet views to a notice telling the users they must be connected to the internet to use this feature. It was in theme with the rest of the application's interface, and was done well/tastefully. They said nothing about it during the approval process, however we did get a personal phone call to verify that we were giving away items that actually pertained to the movie. According to their usually vague agreement, you aren't allowed to have sweepstakes otherwise. I would also think this adheres more strictly to their "only use things if you absolutely need them" ideaology as well. Here's the iTunes link to the application, EvoScanner.

  • Choosing the right .NET architecture. WCF? WPF/Forms, ASP.NET (MVC)?

    - by Tommy Jakobsen
    I’m in the situation that I have to design and implement a rather big system from the bottom. I’m having some (a lot actually) questions about the architecture that I would like your comments and thoughts on. I don’t hope that I’ve written too much here, but I wanted to give you all an idea of what the system is. Quick info about the applications, read if you want: I can’t share much detail about the project, but basically it’s a system where we offer our customer a service to manage their users. We have a hotline where the users call and our hotline uses an (windows) application (intranet) to manage the user’s data, etc. The customer also has a web application where they can see reports, information about their business and users, and the ability to modify their data. Modifying data is not just user data like address and so, but also information about the products/services the user has, which can be complicated. The applications will be built on Microsoft .NET Framework 4, with a MS SQL Server 2008 database. There will be a few applications that have to access this database, such as: Intranet application (used by us and our hotline) Customer web application type 1 Customer web application type 2 Customer web application type n different applications) … Now my big problem is what .NET parts I should use for such a system. For the “backend” I’ve considered using Windows Communication Foundation: Would WCF be a good choice? The intranet application will be an application that has to edit lots of records in the database. It has to be easy to navigate using the keyboard (fast to work with). Has a feature such as “find customer, find that, lookup this, choose this and update that”. What would be the best choice to develop this application in? Would it be WPF or good old Windows Forms? I don’t need all of the fancy graphics features in WPF, like 3D, but the application has to look nice (maybe something like the new Visual Studio/Office tools). And the same question goes for the web pages. They have much the same work to do, but not as many features as the intranet application, and not the same amount of data (much less). That is my questions for now. I’m hoping to get a discussion going that will open my eyes to some of these technologies, helping me decide architecture to go with. I would like to say thanks in advance, and let you all know that any thoughts will be much appreciated.

  • Hotfixing Code running inside Web Container with Groovy

    - by raoulsson
    I have a webapp running that has a bug. I know how to fix it in the sources. However I cannot redeploy the app as I would have to take it offline to do so. (At least not right now). I now want to fix the code "at runtime". Surgery on the living object, so to speak. The app is implemented in Java and is build on top of Seam. I have added a Groovy Console to the app previous to the last release. (A way to run arbitrary code at runtime) The normal way of adding behaviour to a class with Groovy would be similar to this: String.metaClass.foo= { x -> x * x } println "anything".foo(3) This code added the method foo to java.lang.String and prints 9. I can do the same thing with classes running inside my webapp container. New instances will thereafter show the same behaviour: com.my.package.SomeService.metaClass.foo= { x -> x * x } def someService = new com.my.package.SomeService() println someService.foo(3) Works as excpected. All good so far. My problem is now that the container, the web framework, Seam in this case, has already instantiated and cached the classes that I would like to manipulate (that is change their behaviour to reflect my bug fix). Ideally this code would work: com.my.package.SomeService.metaClass.foo= { x -> x * x } def x = org.jboss.seam.Component.getInstance(com.my.package.SomeService) println x.foo(3) However the instantiation of SomeService has already happened and there is no effect. Thus I need a way to make my changes "sticky". Has the groovy magic gone after my script has been run? Well, after logging out and in again, I can run this piece of code and get the expected result: def someService = new com.my.package.SomeService() println someService.foo(3) So the foo method is still around and it looks like my change has been permanent... So I guess the question that remains is how to force Seam to re-instantiate all its components and/or how to permanently make the change on all living instances...?

  • symfony/zend integration - blank screen

    - by user142176
    Hi, I need to use ZendAMF on a symfony project and I'm currently working on integrating the two. I have a frontend app with two modules, one of which is 'gateway' - the AMF gateway. In my frontend app config, I have the following in the configure function: // load symfony autoloading first parent::initialize(); // Integrate Zend Framework require_once('[MY PATH TO ZEND]\Loader.php'); spl_autoload_register(array('Zend_Loader', 'autoload')); The executeIndex function my the gateway actions.class.php looks like this // No Layout $this->setLayout(false); // Set MIME Type $this->getResponse()->setContentType('application/x-amf; charset='.sfConfig::get('sf_charset')); // Disable cause this is a non-html page sfConfig::set('sf_web_debug', false); // Create AMF Server $server = new Zend_Amf_Server(); $server->setClass('MYCLASS'); echo $server->handle(); return sfView::NONE; Now when I try to visit the url for the gateway module, or even the other module which was working perfectly fine until this attempt, I only see a blank screen, with not even the symfony dev bar loaded. Oddly enough, my symfony logs are not being updated as well, which suggests that Synfony is not even being 'reached'. So presumably the error has something to do with Zend, but I have no idea how to figure out what the error could be. One thing I do know for sure is that this is not a file path error, because if I change the path in the following line (a part of frontendConfiguration as shown above), I get a Zend_Amf_Server not found error. So the path must be correct. Also if I comment out this very same line, the second module resumes to normality, and my gateway broadcasts a blank x-amf stream. spl_autoload_register(array('Zend_Loader', 'autoload')); Does anyone have any tips on how I could attach this problem? Thanks P.S. I'm currently running an older version of Zend, which is why I am using Zend_Loader instead of Zend_autoLoader (I think). But I've tried switching to the new lib, but the error still remains. So it's not a version problem as well.

  • Do Websites need Local Databases Anymore?

    - by viatropos
    If there's a better place to ask this, please let me know. Every time I build a new website/blog/shopping-cart/etc., I keep trying to do the following: Extract out common functionality into reusable code (Rubygems and jQuery plugins mostly) If possible, convert that gem into a small service so I never have to deal with a database for the objects involved (by service, I mean something lean and mean, usually built with the Sinatra Web Framework with a few core models). My assumption is, if I can remove dependencies on local databases, that will make it easier and more scalable in the long run (scalable in terms of reusability and manageability, not necessarily database/performance). I'm not sure if that's a good or bad assumption yet. What do you think? I've made this assumption because of the following reason: Most serious database/model functionality has been built on the internet somewhere. Just to name a few: Social Network API: Facebook Messaging API: Twitter Mailing API: Google Event API: Eventbrite Shopping API: Shopify Comment API: Disqus Form API: Wufoo Image API: Picasa Video API: Youtube ... Each of those things are fairly complicated to build from scratch and to make as optimized, simple, and easy to use as those companies have made them. So if I build an app that shows pictures (picasa) on an Event page (eventbrite), and you can see who joined the event (facebook events), and send them emails (google apps api), and have them fill out monthly surveys (wufoo), and watch a video when they're done (youtube), all integrated into a custom, easy to use website, and I can do that without ever creating a local database, is that a good thing? I ask because there's two things missing from the puzzle that keep forcing me to create that local database: Post API RESTful/Pretty Url API While there's plenty of Blogging systems and APIs for them, there is no one place where you can just write content and have it part of some massive thing. For every app, I have to use code for creating pretty/restful urls, and that saves posts. But it seems like that should be a service! Question is, is that what the website is? ...That place to integrate the worlds services for my specific cause... and, sigh, to store posts that only my site has access to. Will everyone always need "their own blog"? Why not just have a profile and write lots of content on an established platform like StackOverflow or Facebook? ... That way I can write apps entirely without a database and know that I'm doing it right. Note: Of course at some point you'd need a database, if you were doing something unique or new. But for the case where you're just rewiring information or creating things like videos, events, and products, is it really necessary anymore??

  • Calling 32 bit unmanaged dlls from C# randomly failing

    - by Bert
    Hi, I'm having an issue when calling 32 bit delphi dll's from c# web site. The code generally runs fine, but occasionally I get an error Unable to load DLL '': The specified module could not be found. (Exception from HRESULT: 0x8007007E). This issue persists until I recycle the app pool for the site, and then it works fine again. On the same server, there is also a web service that is calling the same set of dlls. This web service doesn't seem to have the same issue that the web site has. Both applications are using .net framework 3.5, separate app pools on IIS. Here is the code I'm using to wrap the dlls: public sealed class Mapper { static Mapper instance = null; [DllImport("kernel32.dll")] private static extern bool SetDllDirectory(string lpPathName); private Mapper() { SetDllDirectory(ConfigManager.Path); } public static Mapper Instance { get { if (instance == null) { instance = new Mapper(); } return instance; } } public int Foo(string bar, ref double val) { return Loader.Foo(bar, ref val); } } public static class Loader { [DllImport("some.dll", CallingConvention = CallingConvention.StdCall, CharSet = CharSet.Unicode, EntryPoint = "foo")] public static extern int Foo(string bar, ref double val); } Then I call it like this: double val = 0.0; Mapper.Instance.Foo("bar", ref val); Any ideas as to why it would "randomly" Unable to load DLL '': The specified module could not be found. (Exception from HRESULT: 0x8007007E). The other problem is that I haven't been able to replicate the issue in the development environment. I thought that due to 2 applications calling the same dlls, that there could be some locks occurring. To replicate this, I created an app that spawned multiple threads and repeatedly called the 32bit dlls, and then used the web site to call these same dlls. I still couldn't replicate the issue. Some possible fixes that I can think of: Wrap the 32 bit dlls in web service (because the webservice doesn't seem to suffer from the same problem). But this may be worthless if it turns out that the web service also fails. Set up state server for the session state and periodically recycle the app pool for the site.This isn't fixing the problem, only avoiding it. Wrap the dll's in exe, and call that exe. Then I shouldn't get the same issue. But this also seems like a hacky solution. Implement the mapper class differently ? But how else should I be doing the call? The other draw back is that other applications are using this mapper, so I'd need to change there code too. Thanks

  • Forcing a checkbox bound to a DataSource to update when it has not been viewed yet.

    Here is a test framework to show what I am doing: create a new project add a tabbed control on tab 1 put a button on tab 2 put a check box paste this code for its code (use default names for controls) public partial class Form1 : Form { private List<bool> boolList = new List<bool>(); BindingSource bs = new BindingSource(); public Form1() { InitializeComponent(); boolList.Add(false); bs.DataSource = boolList; checkBox1.DataBindings.Add("Checked", bs, ""); this.button1.Click += new System.EventHandler(this.button1_Click); this.checkBox1.CheckedChanged += new System.EventHandler(this.checkBox1_CheckedChanged); } bool updating = false; private void button1_Click(object sender, EventArgs e) { updating = true; boolList[0] = true; bs.ResetBindings(false); Application.DoEvents(); updating = false; } private void checkBox1_CheckedChanged(object sender, EventArgs e) { if (!updating) MessageBox.Show("CheckChanged fired outside of updating"); } } The issue is if you run the program and look at tab 2 then press the button on tab 1 the program works as expected, however if you press the button on tab 1 then look at tab 2 the event for the checkbox will not fire untill you look at tab 2. The reason for this is the controll on tab 2 is not in the "created" state, so its binding to change the checkbox from unchecked to checked does not happen until after the control has been "Created". checkbox1.CreateControl() does not do anything because according to MSDN CreateControl does not create a control handle if the control's Visible property is false. You can either call the CreateHandle method or access the Handle property to create the control's handle regardless of the control's visibility, but in this case, no window handles are created for the control's children. I tried getting the value of Handle(there is no public CreateHandle() for CheckBox) but still the same result. Any suggestions other than have the program quickly flash all of my tabs that have data-bound check boxes when it first loads? EDIT-- per Jaxidian's suggestion I created a new class public class newcheckbox : CheckBox { public new void CreateHandle() { base.CreateHandle(); } } I call CreateHandle() right after updating = true same results as before.

  • Extending Enums, Overkill?

    - by CkH
    I have an object that needs to be serialized to an EDI format. For this example we'll say it's a car. A car might not be the best example b/c options change over time, but for the real object the Enums will never change. I have many Enums like the following with custom attributes applied. public enum RoofStyle { [DisplayText("Glass Top")] [StringValue("GTR")] Glass, [DisplayText("Convertible Soft Top")] [StringValue("CST")] ConvertibleSoft, [DisplayText("Hard Top")] [StringValue("HT ")] HardTop, [DisplayText("Targa Top")] [StringValue("TT ")] Targa, } The Attributes are accessed via Extension methods: public static string GetStringValue(this Enum value) { // Get the type Type type = value.GetType(); // Get fieldinfo for this type FieldInfo fieldInfo = type.GetField(value.ToString()); // Get the stringvalue attributes StringValueAttribute[] attribs = fieldInfo.GetCustomAttributes( typeof(StringValueAttribute), false) as StringValueAttribute[]; // Return the first if there was a match. return attribs.Length > 0 ? attribs[0].StringValue : null; } public static string GetDisplayText(this Enum value) { // Get the type Type type = value.GetType(); // Get fieldinfo for this type FieldInfo fieldInfo = type.GetField(value.ToString()); // Get the DisplayText attributes DisplayTextAttribute[] attribs = fieldInfo.GetCustomAttributes( typeof(DisplayTextAttribute), false) as DisplayTextAttribute[]; // Return the first if there was a match. return attribs.Length > 0 ? attribs[0].DisplayText : value.ToString(); } There is a custom EDI serializer that serializes based on the StringValue attributes like so: StringBuilder sb = new StringBuilder(); sb.Append(car.RoofStyle.GetStringValue()); sb.Append(car.TireSize.GetStringValue()); sb.Append(car.Model.GetStringValue()); ... There is another method that can get Enum Value from StringValue for Deserialization: car.RoofStyle = Enums.GetCode<RoofStyle>(EDIString.Substring(4, 3)) Defined as: public static class Enums { public static T GetCode<T>(string value) { foreach (object o in System.Enum.GetValues(typeof(T))) { if (((Enum)o).GetStringValue() == value.ToUpper()) return (T)o; } throw new ArgumentException("No code exists for type " + typeof(T).ToString() + " corresponding to value of " + value); } } And Finally, for the UI, the GetDisplayText() is used to show the user friendly text. What do you think? Overkill? Is there a better way? or Goldie Locks (just right)? Just want to get feedback before I intergrate it into my personal framework permanently. Thanks.

  • Mocking a concrete class : templates and avoiding conditional compilation

    - by AshirusNW
    I'm trying to testing a concrete object with this sort of structure. class Database { public: Database(Server server) : server_(server) {} int Query(const char* expression) { server_.Connect(); return server_.ExecuteQuery(); } private: Server server_; }; i.e. it has no virtual functions, let alone a well-defined interface. I want to a fake database which calls mock services for testing. Even worse, I want the same code to be either built against the real version or the fake so that the same testing code can both: Test the real Database implementation - for integration tests Test the fake implementation, which calls mock services To solve this, I'm using a templated fake, like this: #ifndef INTEGRATION_TESTS class FakeDatabase { public: FakeDatabase() : realDb_(mockServer_) {} int Query(const char* expression) { MOCK_EXPECT_CALL(mockServer_, Query, 3); return realDb_.Query(); } private: // in non-INTEGRATION_TESTS builds, Server is a mock Server with // extra testing methods that allows mocking Server mockServer_; Database realDb_; }; #endif template <class T> class TestDatabaseContainer { public: int Query(const char* expression) { int result = database_.Query(expression); std::cout << "LOG: " << result << endl; return result; } private: T database_; }; Edit: Note the fake Database must call the real Database (but with a mock Server). Now to switch between them I'm planning the following test framework: class DatabaseTests { public: #ifdef INTEGRATION_TESTS typedef TestDatabaseContainer<Database> TestDatabase ; #else typedef TestDatabaseContainer<FakeDatabase> TestDatabase ; #endif TestDatabase& GetDb() { return _testDatabase; } private: TestDatabase _testDatabase; }; class QueryTestCase : public DatabaseTests { public: void TestStep1() { ASSERT(GetDb().Query(static_cast<const char *>("")) == 3); return; } }; I'm not a big fan of that compile-time switching between the real and the fake. So, my question is: Whether there's a better way of switching between Database and FakeDatabase? For instance, is it possible to do it at runtime in a clean fashion? I like to avoid #ifdefs. Also, if anyone has a better way of making a fake class that mimics a concrete class, I'd appreciate it. I don't want to have templated code all over the actual test code (QueryTestCase class). Feel free to critique the code style itself, too. You can see a compiled version of this code on codepad.

  • LINQ Query Returning Multiple Copies Of First Result

    - by Mike G
    I'm trying to figure out why a simple query in LINQ is returning odd results. I have a view defined in the database. It basically brings together several other tables and does some data munging. It really isn't anything special except for the fact that it deals with a large data set and can be a bit slow. I want to query this view based on a long. Two sample queries below show different queries to this view. var la = Runtime.OmsEntityContext.Positions.Where(p => p.AccountNumber == 12345678).ToList(); var deDa = Runtime.OmsEntityContext.Positions.Where(p => p.AccountNumber == 12345678).Select(p => new { p.AccountNumber, p.SecurityNumber, p.CUSIP }).ToList(); The first one should hand back a List. The second one will be a list of anonymous objects. When I do these queries in entities framework the first one will hand me back a list of results where they're all exactly the same. The second query will hand me back data where the account number is the one that I queried and the other values differ. This seems to do this on a per account number basis, ie if I were to query for one account number or another all the Position objects for one account would have the same value (the first one in the list of Positions for that account) and the second account would have a set of Position objects that all had the same value (again, the first one in it's list of Position objects). I can write SQL that is in effect the same as either of the two EF queries. They both come back with results (say four) that show the correct data, one account number with different securities numbers. Why does this happen??? Is there something that I could be doing wrong so that if I had four results for the first query above that the first record's data also appears in the 2-4th's objects??? I cannot fathom what would/could be causing this. I've searched Google for all kinds of keywords and haven't seen anyone with this issue. We partial class out the Positions class for added functionality (smart object) and some smart properties. There are even some constructors that provide some view model type support. None of this is invoked in the request (I'm 99% sure of this). However, we do this same pattern all over the app. The only thing I can think of is that the mapping in the EDMX is screwy. Is there a way that this would happen if the "primary keys" in the EDMX were not in fact unique given the way the view is constructed? I'm thinking that the dev who imported this model into the EDMX let the designer auto select what would be unique. Any help would give a haggered dev some hope!

  • Constructor versus setter injection

    - by Chris
    Hi, I'm currently designing an API where I wish to allow configuration via a variety of methods. One method is via an XML configuration schema and another method is through an API that I wish to play nicely with Spring. My XML schema parsing code was previously hidden and therefore the only concern was for it to work but now I wish to build a public API and I'm quite concerned about best-practice. It seems that many favor javabean type PoJo's with default zero parameter constructors and then setter injection. The problem I am trying to tackle is that some setter methods implementations are dependent on other setter methods being called before them in sequence. I could write anal setters that will tolerate themselves being called in many orders but that will not solve the problem of a user forgetting to set the appropriate setter and therefore the bean being in an incomplete state. The only solution I can think of is to forget about the objects being 'beans' and enforce the required parameters via constructor injection. An example of this is in the default setting of the id of a component based on the id of the parent components. My Interface public interface IMyIdentityInterface { public String getId(); /* A null value should create a unique meaningful default */ public void setId(String id); public IMyIdentityInterface getParent(); public void setParent(IMyIdentityInterface parent); } Base Implementation of interface: public abstract class MyIdentityBaseClass implements IMyIdentityInterface { private String _id; private IMyIdentityInterface _parent; public MyIdentityBaseClass () {} @Override public String getId() { return _id; } /** * If the id is null, then use the id of the parent component * appended with a lower-cased simple name of the current impl * class along with a counter suffix to enforce uniqueness */ @Override public void setId(String id) { if (id == null) { IMyIdentityInterface parent = getParent(); if (parent == null) { // this may be the top level component or it may be that // the user called setId() before setParent(..) } else { _id = Helpers.makeIdFromParent(parent,getClass()); } } else { _id = id; } } @Override public IMyIdentityInterface getParent() { return _parent; } @Override public void setParent(IMyIdentityInterface parent) { _parent = parent; } } Every component in the framework will have a parent except for the top level component. Using the setter type of injection, then the setters will have different behavior based on the order of the calling of the setters. In this case, would you agree, that a constructor taking a reference to the parent is better and dropping the parent setter method from the interface entirely? Is it considered bad practice if I wish to be able to configure these components using an IoC container? Chris

  • Why does my JSF + Spring web application output JSF source code instead of interpreted HTML page?

    - by Corvus
    I'm new to both JSF and Spring Framework and I'm trying to figure out how to make them work together. My current problem is that application outputs my JSF files without interpreting them. Here are some snippets of my code which I believe might be relevant: dispatcher-servlet.xml <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="login.htm">loginController</prop> </props> </property> </bean> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/pages/" p:suffix=".xhtml" /> <bean name="loginController" class="controller.LoginController" /> loginController public class LoginController extends MultiActionController { public ModelAndView login(HttpServletRequest request, HttpServletResponse response) throws Exception { System.out.println("LOGIN"); return new ModelAndView("login"); } WEB-INF/pages/login.xhtml <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"> <h:head> <title>#{message.log}</title> </h:head> <h:body> <h:form> <h:outputLabel value="#{message.username}" for="userName"> <h:inputText id="userName" value="#{User.name}" /> </h:outputLabel> <h:commandButton value="#{message.loggin}" action="#{User.login}" /> </h:form> </h:body> </html> Any ideas where the problem might be? Does this code make any sense at all? I'm well aware of fact, that probably completely sucks and I'll be glad to here WHY it sucks and how to make it better. Thanks :)

  • How do I integrate a new MVC C# Project with an existing Web Forms VB.NET Web Application Project?

    - by Jordan Rieger
    We have a corporate website with a large amount of dynamic business application pages (e.g. Shopping Cart, Helpdesk, Product/Service management, Reporting, etc.) The site was built as an ASP.Net Web Application Project (WAP). Our systems have evolved over the years to use .NET 4.5 and various custom business logic DLLs (written in a mix of C# and VB.NET). However, the site itself is still using VB.NET Web Forms. We now have done a few side projects in MVC 4 using Razor/C#, and we want to use this framework for new pages on the main corporate site going forward. What would be the easiest way to achieve this? I found this nice list of steps to integrate MVC 4 into an existing Web Forms app. The problem is that because our existing app is a VB.NET WAP, it compiles into a single DLL, and .NET allows only one language per DLL. The site is way too big for us to contemplate converting it to C# all at once (yes, I've looked at the conversion tools, and they're good, but even 99% accuracy would leave us a huge amount of cleanup work.) I thought about converting the existing WAP into a Web Site Project (WSP) which does allow mixing languages and then following the steps above, but after a few pages of Google results, I couldn't find any steps for converting a WAP to WSP. (Plenty of sites offer the reverse steps: converting a WSP to a WAP.) Another idea I had was to create a completely separate MVC project, and then somehow squish them together into the same folder structure, where they would share the bin folder but compile to separate DLL's. I have no idea if this is possible, because certain files would collide (e.g. Global.asax, web.config, etc.) Finally, I can imagine a compromise solution where we keep all the MVC stuff in its own separate application under a subfolder of the main solution. We already use our own custom session state solution, so it wouldn't be difficult to pass data between the old site to the new pages. Which of the ideas above do you think makes the most sense for us? Is there another solution that I'm missing?

  • Why no switch on pointers?

    - by meeselet
    For instance: #include <stdio.h> void why_cant_we_switch_him(void *ptr) { switch (ptr) { case NULL: printf("NULL!\n"); break; default: printf("%p!\n", ptr); break; } } int main(void) { void *foo = "toast"; why_cant_we_switch_him(foo); return 0; } gcc test.c -o test test.c: In function 'why_cant_we_switch_him': test.c:5: error: switch quantity not an integer test.c:6: error: pointers are not permitted as case values Just curious. Is this a technical limitation? EDIT People seem to think there is only one constant pointer expression. Is that is really true, though? For instance, here is a common paradigm in Objective-C (it is really only C aside from NSString, id and nil, which are merely a pointers, so it is still relevant — I just wanted to point out that there is, in fact, a common use for it, despite this being only a technical question): #include <stdio.h> #include <Foundation/Foundation.h> static NSString * const kMyConstantObject = @"Foo"; void why_cant_we_switch_him(id ptr) { switch (ptr) { case kMyConstantObject: // (Note that we are comparing pointers, not string values.) printf("We found him!\n"); break; case nil: printf("He appears to be nil (or NULL, whichever you prefer).\n"); break; default: printf("%p!\n", ptr); break; } } int main(void) { NSString *foo = @"toast"; why_cant_we_switch_him(foo); foo = kMyConstantObject; why_cant_we_switch_him(foo); return 0; } gcc test.c -o test -framework Foundation test.c: In function 'why_cant_we_switch_him': test.c:5: error: switch quantity not an integer test.c:6: error: pointers are not permitted as case values It appears that the reason is that switch only allows integral values (as the compiler warning said). So I suppose a better question would be to ask why this is the case? (though it is probably too late now.)

  • Hide a base class method from derived class, but still visible outside of assembly

    - by clintp
    This is a question about tidyness. The project is already working, I'm satisfied with the design but I have a couple of loose ends that I'd like to tie up. My project has a plugin architecture. The main body of the program dispatches work to the plugins that each reside in their own AppDomain. The plugins are described with an interface, which is used by the main program (to get the signature for invoking DispatchTaskToPlugin) and by the plugins themselves as an API contract: namespace AppServer.Plugin.Common { public interface IAppServerPlugin { void Register(); void DispatchTaskToPlugin(Task t); // Other methods omitted } } In the main body of the program Register() is called so that the plugin can register its callback methods with the base class, and then later DispatchTaskToPlugin() is called to get the plugin running. The plugins themselves are in two parts. There's a base class that implements the framework for the plugin (setup, housekeeping, teardown, etc..). This is where DispatchTaskToPlugin is actually defined: namespace AppServer.Plugin { abstract public class BasePlugin : MarshalByRefObject, AppServer.Plugin.Common.IAppServerPlugin { public void DispatchTaskToPlugin(Task t) { // ... // Eventual call to actual plugin code // } // Other methods omitted } } The actual plugins themselves only need to implement a Register() method (to give the base class the delegates to call eventually) and then their business logic. namespace AppServer.Plugin { public class Plugin : BasePlugin { override public void Register() { // Calls a method in the base class to register itself. } // Various callback methods, business logic, etc... } } Now in the base class (BasePlugin) I've implemented all kinds of convenience methods, collected data, etc.. for the plugins to use. Everything's kosher except for that lingering method DispatchTaskToPlugin(). It's not supposed to be callable from the Plugin class implementations -- they have no use for it. It's only needed by the dispatcher in the main body of the program. How can I prevent the derived classes (Plugin) from seeing the method in the base class (BasePlugin/DispatchTaskToPlugin) but still have it visible from outside of the assembly? I can split hairs and have DispatchTaskToPlugin() throw an exception if it's called from the derived classes, but that's closing the barn door a little late. I'd like to keep it out of Intellisense or possibly have the compiler take care of this for me. Suggestions?

  • How to listen for file system changes MAC - kFSEventStreamCreateFlagWatchRoot

    - by Cocoa Newbie
    Hi All, I am listening for Directory and disk changes in a COCOA project using FSEvents. I need to get events when a root folder is renamed or deleted. So, I passed kFSEventStreamCreateFlagWatchRoot while creating the FSEventStream.But even if I delete or rename the root folder I am not getting corresponding FSEventStreamEventFlags. Any idea what could possibly be the issue. I am listening for changes in a USB mounted device. I used both FSEventStreamCreate and FSEventStreamCreateRelativeToDevice. One thing I notices is when I try with FSEventStreamCreate I get the following error message while creating FSEventStream: (CarbonCore.framework) FSEventStreamCreate: watch_all_parents: error trying to add kqueue for fd 7 (/Volumes/NO NAME; Operation not supported) But with FSEventStreamCreateRelativeToDevice there are no errors but still not getting kFSEventStreamEventFlagRootChanged in event flags. Also, while creation using FSEventStreamCreateRelativeToDevice apple say's if I want to listen to root path changes pass emty string "". But I am not able to listen to root path changes by passing empty string. But when I pass "/" it works. But even for "/" I do not get any proper FSEventStreamEventFlags. I am pasting the code here: -(void) subscribeFileSystemChanges:(NSString*) path { PRINT_FUNCTION_BEGIN; // if already subscribed then unsubscribe if (stream) { FSEventStreamStop(stream); FSEventStreamInvalidate(stream); /* will remove from runloop */ FSEventStreamRelease(stream); } FSEventStreamContext cntxt = {0}; cntxt.info = self; CFArrayRef pathsToWatch = CFArrayCreate(NULL, (const void**)&path, 1, NULL); stream = FSEventStreamCreate(NULL, &feCallback, &cntxt, pathsToWatch, kFSEventStreamEventIdSinceNow, 1, kFSEventStreamCreateFlagWatchRoot ); FSEventStreamScheduleWithRunLoop(stream, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode); FSEventStreamStart(stream); } call back function: static void feCallback(ConstFSEventStreamRef streamRef, void* pClientCallBackInfo, size_t numEvents, void* pEventPaths, const FSEventStreamEventFlags eventFlags[], const FSEventStreamEventId eventIds[]) {? char** ppPaths = (char**)pEventPaths; int i; for (i = 0; i < numEvents; i++) { NSLog(@"Event Flags %lu Event Id %llu", eventFlags[i], eventIds[i]); NSLog(@"Path changed: %@", [NSString stringWithUTF8String:ppPaths[i]]); } } Thanks a lot in advance.

  • Using a Button to navigate to another Page in a NavigationWindow

    I'm trying to use the navigation command framework in WPF to navigate between Pages within a WPF application (desktop; not XBAP or Silverlight). I believe I have everything configured correctly, yet its not working. I build and run without errors, I'm not getting any binding errors in the Output window, but my navigation button is disabled. Here's the app.xaml for a sample app: <Application x:Class="Navigation.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" StartupUri="First.xaml"> </Application> Note the StartupUri points to First.xaml. First.xaml is a Page. WPF automatically hosts my page in a NavigationWindow. Here's First.xaml: <Page x:Class="Navigation.First" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="First"> <Grid> <Button CommandParameter="/Second.xaml" CommandTarget="{Binding RelativeSource= {RelativeSource FindAncestor, AncestorType={x:Type NavigationWindow}}}" Command="NavigationCommands.GoToPage" Content="Go!"/> </Grid> </Page> The button's CommandTarget is set to the NavigationWindow. The command is GoToPage, and the page is /Second.xaml. I've tried setting the CommandTarget to the containing Page, the CommandParameter to "Second.xaml" (First.xaml and Second.xaml are both in the root of the solution), and I've tried leaving the CommandTarget empty. I've also tried setting the Path to the Binding to various navigational-related public properties on the NavigationWindow. Nothing has worked so far. What am I missing here? I really don't want to do my navigation in code. Clarification. If, instead of using a button, I use a Hyperlink: <Grid> <TextBlock> <Hyperlink NavigateUri="Second.xaml">Go! </Hyperlink> </TextBlock> </Grid> everything works as expected. However, my UI requirements means that using a Hyperlink is right out. I need a big fatty button for people to press. That's why I want to use the button to navigate. I just want to know how I can get the Button to provide the same ability that the Hyperlink does in this case.

  • Move namespace declaration from payload to envelope on an axis created web service

    - by rmarimon
    I just created a web service client using axis and eclipse that does not work with my web service provider. The message created by the web service client looks like this: <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <enviarMensajeRequest xmlns="http://www.springframework.org/spring-ws/Imk-Zenkiu-Services"> <usuario>someuser</usuario> <clave>somepassword</clave> <mensaje>somemessage</mensaje> <contacto> <buzonSMS>somenumber</buzonSMS> <primerNombre>somefirstname</primerNombre> <primerApellido>somelastname</primerApellido> </contacto> </enviarMensajeRequest> </soapenv:Body> </soapenv:Envelope> I see nothing wrong with the message but my provider insists the message should be: <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:imk="http://www.springframework.org/spring-ws/Imk-Zenkiu-Services"> <soapenv:Body> <imk:enviarMensajeRequest> <imk:usuario>someuser</imk:usuario> <imk:clave>somepassword</imk:clave> <imk:mensaje>somemessage</imk:mensaje> <imk:contacto> <imk:buzonSMS>somenumber</imk:buzonSMS> <imk:primerNombre>somefirstname</imk:primerNombre> <imk:primerApellido>somelastname</imk:primerApellido> </imk:contacto> </imk:enviarMensajeRequest> </soapenv:Body> </soapenv:Envelope> Notice the namespace declaration moving from the enviarMensajeRequest to the soapenv:Envelope and the qualification with imk: on the parameters. I've tried many combinations on the process but my web service, wsdl and xml knowledge is very limited. The provider says that they can't help beyond telling me this. Any ideas? Perhaps a different framework that I can use to create the correct client.
