  • Is there a SortedList<T> class in .net ? (not SortedList<Key,Value> which is actually a kind of Sort

    - by Brann
    I need to sort some objects according to their contents (in fact according to one of their properties, which is NOT the key and may be duplicated between different objects) .net provides two classes (SortedDictionnary and SortedList), and both are some kind of Dictionaries. The only difference (AFAIK) is that SortedDictionnary uses a binary tree to maintain its state whereas SortedList does not and is accessible via an index. I could achieve what I want using a List, and then using its Sort() method with a custom implementation of IComparer, but it wouldn't be time-efficient as I would sort the whole List each time I insert a new object, whereas a good SortedList would just insert the item at the right position. What I need is a SortedList class with a RefreshPosition(int index) to move only the changed (or inserted) object rather than resorting the whole list each time an object inside changes. Am I missing something obvious ?

  • Visual Studio Pre build events and batch set

    - by helloworld922
    Hi, I'm trying to create call a batch file which sets a bunch of environment variables prior to building. The batch file looks something like this (it's automatically generated before-hand to detect ATI Stream SDK or NVidia CUDA toolkit): set OCL_LIBS_X86="%ATISTREAMSDKROOT%libs\x86" set OCL_LIBS_X64="%ATISTREAMSDKROOT%libs\x86_64" set OCL_INCLUDE="%ATISTREAMSDKROOT%include" However, the rest of the build doesn't seem to have access to these variables, so when I try to reference $(OCL_INCLUDE) in the C/C++GeneralAdditional include directories, it will first give me warning that environment variable $(OCL_INCLUDE) was not found, and when I try to include CL/cl.hpp the compile will fail with: fatal error C1083: Cannot open include file: 'CL/cl.hpp': No such file or directory I know that I could put these variables into the registry if I wanted to access them from the visual studio GUI, but I would really prefer not to do this. Is there a way to to get these environment variables to stick after the pre-build events? I can't reference $(ATISTREAMSDKROOT) directly because the project must be able to build for both ATI Stream and NVidia Cuda.

  • Entity Fremework serialization

    - by Alexandr
    Hello guys! I was confused with my problem. I'm using Entity Framework and want to save entities on hard disk and then to restore them. I have no problem with Serializing/Deserializing but i get an exception "The object cannot be added to the ObjectStateManager because it already has an EntityKey. Use ObjectContext.Attach to attach an object that has an existing key" when i try to add deserialized object to my datacontext. And nothing happens when i just Attach my entity to datacontext How to achieve my goal? Thx in advance! -Alexandr-

  • Actionscript 3: How to remove all black pixels from BitmapData ?

    - by Adnan Doric
    Hello, Let say I have a BitmapData with different pixels representing an object, and some black pixels around it that I want to remove. I would like to obtain a new BitmapData, with width and height of the object represented by non-black pixels. For example, let say I have a BitmapData 400x400px, but the object represented by non-black pixels occupies the rect: x=100, y=100, width=200, height=200. I want to get new BitmapData representing that rect, all black pixels should be removed. Any idea on how to do this please ?

  • listing the functions of a web service

    - by Jankhana
    hi, I wanted to make an application that will take either the path of the dll or Webservice and list me all the functions present in that dll. I accomplished the listing of the function using this but I am not able to list the functions of the Webservices. Using Assembly.GetMembers() it's listing the Function Name with the Parameters Type and I am not able to get the Parameters Name. How shall i get that? While debugging I found that m_parameters is a nonpublic member and i'm not able to get the Parameter name. Is that possible??? And one more question is how shall i list the functions available in the web service without including the web reference or service reference in the windows application using C#.

  • Isn't the C++ standard library backward-compatible?

    - by Chris Metzler
    Hi. I'm working on a 64-bit Linux system, trying to build some code that depends on third-party libraries for which I have binaries. During linking, I get a stream of undefined reference errors for one of the libraries, indicating that the linker couldn't resolve references to standard C++ functions/classes, e.g.: librxio.a(EphReader.o): In function `gpstk::EphReader::read_fic_data(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)': EphReader.cpp:(.text+0x27c): undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::__ostream_insert<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*, long)' EphReader.cpp:(.text+0x4e8): undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::__ostream_insert<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*, long)' I'm not really a C++ programmer, but this looks to me like it can't find the standard library. Doing some more research, I got the following when I looked at librxio's dependency for the standard library: $ ldd librxio.so.16.0 ./librxio.so.16.0: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by ./librxio.so.16.0) libm.so.6 => /lib64/libm.so.6 (0x00002aaaaad45000) libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00002aaaaafc8000) libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00002aaaab2c8000) libc.so.6 => /lib64/libc.so.6 (0x00002aaaab4d7000) /lib64/ld-linux-x86-64.so.2 (0x0000555555554000) So I read that as saying that librxio (one of the third-party libraries) requires at least v3.4.9 of the standard library. But the version I have installed is 4.1.2: $ rpm -qa | grep libstdc compat-libstdc++-33-3.2.3-61.x86_64 libstdc++-devel-4.1.2-14.el5.i386 libstdc++-devel-4.1.2-14.el5.x86_64 libstdc++-4.1.2-14.el5.x86_64 libstdc++-4.1.2-14.el5.i386 Shouldn't this work? The shared object major number is 6, same as for v3.4.9. At this level, shouldn't this be backward compatible? It seems like the third-party library is looking for an earlier version of the standard library than what I have installed; but isn't there backward compatibility between versions with the same major number for the shared library? Again, I'm not really a C++ programmer; but I don't see what the problem is. Any advice greatly appreciated. Thanks.

  • Drupal: Content in blocks from node_reference fields?

    - by Marco
    After only a few weeks of working with Drupal I've come up with a recurring problem, which I don't really have an optimal solution to, so I'm hoping that someone here might be able to give some best practice pointers. What I have is a region inside my node.tpl.php, which is populated with blocks that display content from two different CCK fields of the type node_reference. This works fine when displaying a single node. The problem appears when I need to use a view. For example, lets say I have a news listing, and a single news item view. When I display the single news item I can use the news node node_reference field to reference whatever material I would like to have in my sidebar, but when on the news listing view I would like to reference nodes separately. What would be the best practice to solve this? I'm having a few ideas, but none seem like the logical choice, how would you do?

  • Fleunt NHibernate not working outside of nunit test fixtures

    - by thorkia
    Okay, here is my problem... I created a Data Layer using the RTM Fluent Nhibernate. My create session code looks like this: _session = Fluently.Configure(). Database(SQLiteConfiguration.Standard.UsingFile("Data.s3db")) .Mappings( m => { m.FluentMappings.AddFromAssemblyOf<ProductMap>(); m.FluentMappings.AddFromAssemblyOf<ProductLogMap>(); }) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); When I reference the module in a test project, then create a test fixture that looks something like this: [Test] public void CanAddProduct() { var product = new Product {Code = "9", Name = "Test 9"}; IProductRepository repository = new ProductRepository(); repository.AddProduct(product); using (ISession session = OrmHelper.OpenSession()) { var fromDb = session.Get<Product>(product.Id); Assert.IsNotNull(fromDb); Assert.AreNotSame(fromDb, product); Assert.AreEqual(fromDb.Id, product.Id); } My tests pass. When I open up the created SQLite DB, the new Product with Code 9 is in it. the tables for Product and ProductLog are there. Now, when I create a new console application, and reference the same library, do something like this: Product product = new Product() {Code = "10", Name = "Hello"}; IProductRepository repository = new ProductRepository(); repository.AddProduct(product); Console.WriteLine(product.Id); Console.ReadLine(); It doesn't work. I actually get pretty nasty exception chain. To save you lots of head aches, here is the summary: Top Level exception: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.\r\n\r\n The PotentialReasons collection is empty The Inner exception: The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found. Ensure that the assembly System.Data.SQLite is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use element in the application configuration file to specify the full name of the assembly. Both the unit test library and the console application reference the exact same version of System.Data.SQLite. Both projects have the exact same DLLs in the debug folder. I even tried copying SQLite DB the unit test library created into the debug directory of the console app, and removed the build schema lines and it still fails If anyone can help me figure out why this won't work outside of my unit tests it would be greatly appreciated. This crazy bug has me at a stand still.

  • OpenCMS - Best approach for showing rotating references

    - by user197127
    Hi, I would like to add on the right column of my site a rotating references section. Each reference would have some text + name of person + company name. It does not need to be structured (open text is also ok). I would then want opencms to rotate between 20 difference references each time a page is displayed. I can keep a session scope counter holding which reference we last showed. I need a way to manage the references (users not programmers) over time. My question is which would be the best way to do so? Thanks

  • How can I pass a javaScript function to a Java Method to act as a callback (Rhino)

    - by Dan Howard
    Hi everyone, Basically I'm trying to pass a javaScript function to a Java method to act as a callback to the script. I can do it - sort of - but the object I receive is a sun.org.mozilla.javascript.internal.InterpretedFunction and I don't see a way to invoke it. Any ideas? Here's what I have so far: var someNumber = 0; function start() { // log is just an log4j instance added to the Bindings log.info("started...."); someNumber = 20; // Test is a unit test object with this method on it (taking Object as a param). test.callFromRhino(junk); } function junk() { log.info("called back " + someNumber); }

  • Can DBRefs contain additional fields?

    - by Soviut
    I've encountered several situations when using MongoDB that require the use of DBRefs. However, I'd also like to cache some fields from the referenced document in the DBRef itself. {$ref:'user', $id:'10285102912A', username:'Soviut'} For example, I may want to have the username available even though the user document is referenced. This would provide me all the benefits of a single document approach; Faster querying and eliminating the need to do manual dereferencing in my code. While at the same time allowing me to use references where they make sense. The idea being that when the referenced document is updated (a user changes their name, for example) my business layer can automatically update all the documents that reference it. Ultimately, I'm wondering if it's considered good form to store additional fields on my DBRefs? Will it break anything? Will I lose my data each time a reference is rewritten? Will drivers like pymongo support it?

  • What trick will give most reliable/compatible sound alarm in a browser window for most browsers

    - by Dirk Paessler
    I want to be able to play an alarm sound using Javascript in a browser window, preferably with the requirement for any browser plugins (Quicktime/Flash). I have been experimenting with the tag and the new Audio object in Javascript, but results are mixed: As you can see, there is no variant that works on all browsers. Do I miss a trick that is more cross-browser compatible? This is my code: // mp3 with Audio object var snd = new Audio("/sounds/beep.mp3");snd.play(); // wav with Audio object var snd = new Audio("/sounds/beep.wav");snd.play(); // mp3 with EMBED tag $("#alarmsound").empty().append ('<embed src="/sounds/beep.mp3" autostart="true" loop="false" '+ 'volume="100" hidden="true" width="1" height="1" />'); // wav with EMBED tag $("#alarmsound").empty().append ('<embed src="/sounds/beep.wav" autostart="true" loop="false" '+ 'volume="100" hidden="true" width="1" height="1" />'); }

  • How to access SharePoint web part properties?

    - by shannon.stewart
    I have created a feature for SharePoint 2007 that has a web part. I have added a custom property to the web part like so: [Personalizable(PersonalizationScope.Shared)] [WebBrowsable(true)] [Category("My Custom Properties")] [WebDisplayName("ServiceURL")] [WebDescription("The URL for the Wcf service")] public string ServiceURL { get; set; } Along with this web part, I've added a custom page that the web part will have a link to. I would like to reference the web part property from the custom page, but I don't know where these properties are stored. I've tried to access it using the code below, but both property collections don't have any properties stored. SPFeaturePropertyCollection spProperties = SPContext.Current.Site.Features[this.FeatureGuid].Properties; or SPFeaturePropertyCollection spProperties = SPContext.Current.Site.Features[this.FeatureGuid].Definition.Properties; My question is how can I get a reference to the web part property from other pages?

  • Spring/Hibernate: InvocationTargetException when deleting entity

    - by niklassaers
    I'm sorry if this question is a bit vague, but I'm quite confused. I've got a controller that calls a service to delete an entity and then create an entity in its place. In the service, I've got my DAO, and my entity, and I want to delete my entity, so I call DAO.delete(entity); Then, seemingly out of nowhere, I get an InvocationTargetException. The parameters here are: method: public org.springframework.web.servlet.ModelAndView tld.myproject.view.web.controller.MyController.replaceEntity(org.springframework.web.multipart.MultipartFile,javax.servlet.http.HttpServletRequest) target: tld.myproject.view.web.controller.MyController@185918e args: [org.springframework.web.multipart.commons.CommonsMultipartFile@14812a6, org.springframework.web.multipart.support.DefaultMultipartHttpServletRequest@c08a64] ex: java.lang.reflect.InvocationTargetException private Object doInvokeMethod(Method method, Object target, Object[] args) throws Exception { ReflectionUtils.makeAccessible(method); try { return method.invoke(target, args); } catch (InvocationTargetException ex) { ReflectionUtils.rethrowException(ex.getTargetException()); } throw new IllegalStateException("Should never get here"); } Does anyone have a suggestion to what's going on? Anything I can use in my debugging? Cheers Nik

  • ASP.NET - Themes and Relative Referencing

    - by user70192
    Hello, I have an ASP.NET application that uses themes. Let's pretend I have a theme named "MySkin". I have a page that is in a sub-directory of my application. When I reference a page that uses "MySkin", I noticed that ASP.NET renders a link element that walks up to the root of the site and then down into the App_Themes directory. Here is an example link element I found in a rendered ASP.NET page: <link href="../../App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is there a reason that the rendered link element does not use the following instead: <link href="/App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is this a browser compatibility issue or is there another reason? The reason I am asking is because I am rendering my ASP.NET page using Server.Execute and storing the result in a different directory. Because of this, I would prefer to use the second way to reference my theme's css. Thank you!

  • WCF reuse types in referenced assemblies does not reuse the ServiceContract Interface

    - by Matt
    I have three seperate projects: -MyUserControl (Needs a reference to a service implementing IMyService) -MyService (Implements IMyService) -MySharedInterfaces (IMyUserControl and IMyService) -MyWebApp The user control needs to be dynamically loaded at runtime. This implements IMyUserControl and has a property of type IMyService which will be set at runtime. The trouble is even with the option to reuse types the WebApp isn't reusing the IMyServiceType, it always generates it again from the Service Reference. This wouldn't be an issue if I could cast it to MySharedInterfaces.IMyService (which I can't understand, since it should be exactly the same). The user control is expecting something of type IMyService, is there anyway to either cast the WebServiceReference.IMyService back to MySharedInterface.IMyServiceReference or force the WebServiceReference to reuse the MySharedInterface.IMyServiceReference? Thanks

  • setting value to the instance of primitive types

    - by Samreen
    I have a function which performs some operation i.e. fetches some data from database. The generic it takes is primitive type always i.e. int, char, bool, string etc. I can easily create its instance. But I can't set the value that I have fetched from database to this instance. public T PerformOperation<T>() { object instance = (T)Activator.CreateInstance(typeof(T)); object result=FetchData(); instance = (T)result; //It gives error on this statement } The function is called as: int result = PerformOperation<int>(); Is there some way of casting the object Type to any generic type which is always primitive?

  • How do I Moq It.IsAny for an array in the setup of a method?

    - by Graham
    I'm brand new to Moq (using v 4) and am struggling a little with the documentation. What I'm trying to do is to Moq a method that takes a byte array and returns an object. Something like: decoderMock.Setup(d => d.Decode(????).Returns(() => tagMock.Object); The ???? is where the byte[] should be, but I can't work out how to make it so that I don't care what's in the byte array, just return the mocked object I've already set up. Moq.It.IsAny expects a generic. Any help please?

  • [Java] - Problem having my main thread sleeping

    - by Chris
    I'm in a Java class and our assignment is to let us explore threads in Java. So far so good except for this one this one problem. And I believe that could be because of my lack of understanding how Java threads work at the moment. I have the main thread of execution which spawns new threads. In the main thread of execution in main() I am calling Thread.sleep(). When I do I get an Unhandled exception type InterruptedException. I am unsure of why I am getting this? I thought this was because I needed a reference to the main thread so I went ahead and made a reference to it via Thread.currentThread(). Is this not the way to have the thread sleep? What I need to do is have the main thread wait/sleep/delay till it does it required work again. Any help would be much appreciated.

  • Humor in code

    - by pfranza
    When you are writing code or naming products, which sources of cultural references are you most likely to draw from? Which reference sources do you think are more likely to be universally understood? For example when findbugs sees that you've implemented equals() without overriding hashCode() it suggest that you implement it by returning 42 (a reference from HHGTTG) Or why we have big endian vs little endian encoding, referencing Gulliver's Travels Not that we should act unprofessionally with our code, but if you going to tell a person that they could only (watch/read/...) one (book/movie/show/...) which one would allow them to 'get' the most jokes?

  • Multiple Controls on a Page with Multiple Instances of Javascript

    - by mattdell
    I have created a Web Control in ASP for use in integrating with Telligent CommunityServer. The control is written in ASP with some 10 lines of C# backend for controlling visibility of the UI elements based on permissions, but I'd say 90% of the functionality is straight-up Javascript. The control works beautifully, until you drop two instances of the Control on the same page--since they reference the exact same Javascript functions, only one control works. How can I take this functionality that I have, this 1200 lines of Javascript, and make it so that each instance of the control can reference its each unique instance of Javascript?

  • Swift CMutablePointers in factories e.g. NewMusicSequence

    - by Gene De Lisa
    How do you use C level factory methods in Swift? Let's try using a factory such as NewMusicSequence(). OSStatus status var sequence:MusicSequence status=NewMusicSequence(&sequence) This errors out with "error: variable 'sequence' passed by reference before being initialized". Set sequence to nil, and you get EXC_BAD_INSTRUCTION. You can try being explicit like this: var sp:CMutablePointer<MusicSequence>=nil status=NewMusicSequence(sp) But then you get a bad access exception when you set sp to nil. If you don't set sp, you get an "error: variable 'sp' used before being initialized" Here's the reference.
