  • VSTS 2010 SGEN : error : Could not load file or assembly (Exception from HRESULT: 0x80131515)

    - by Developer IT
    Hi ! I am experiencing a strange issue with VS2010. We use TFS to build our API dlls and we used to reference them in our projects usign a mapped network drive that was fully trusted. We have been working like that for at least two years and everything worked perfectly. Today, I converted a webapp to vs2010 and when I compile it in Release, it's giving me: SGEN : error : Could not load file or assembly 'file:///L:\Api\Release API_20100521.1\Release\CS.API.Exceptions.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) The strange thing is that it's working when it's under the Debug profile... I tried adding the <runtime> <loadFromRemoteSources enabled="true" /> </runtime> into app.config and still no luck (See http://social.msdn.microsoft.com/Forums/en/msbuild/thread/d12f6301-85bf-4b9e-8e34-a06398a60df0 and http://msdn.microsoft.com/en-us/library/dd409252(VS.100).aspx) I am pretty sure that this issue is from visual studio or msbuild, as our code won't run from a network share when in prod because all the referenced dll's are copied into the bin folder. If anyone has an solution (or just an idea for a search path) please let me know !

  • NullPointerException when showing JFileChooser

    - by Geo
    I show a JFileChooser with this snippet: public File getDestination() { JFileChooser chooser = new JFileChooser(); chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); int option = chooser.showSaveDialog(null); if(option == JFileChooser.APPROVE_OPTION) { return chooser.getSelectedFile().getAbsolutePath(); } return new File("."); } Usually, the first time it's showed, it displays & works correctly. The second time, it will always throw this exception: Exception in thread "Basic L&F File Loading Thread" java.lang.NullPointerException at sun.awt.shell.Win32ShellFolder2.pidlsEqual(Unknown Source) at sun.awt.shell.Win32ShellFolder2.equals(Unknown Source) at sun.awt.shell.Win32ShellFolderManager2.isFileSystemRoot(Unknown Source) at sun.awt.shell.ShellFolder.isFileSystemRoot(Unknown Source) at javax.swing.filechooser.FileSystemView.isFileSystemRoot(Unknown Source) at javax.swing.filechooser.WindowsFileSystemView.isTraversable(Unknown Source) at javax.swing.JFileChooser.isTraversable(Unknown Source) at javax.swing.plaf.basic.BasicDirectoryModel$LoadFilesThread.run0(Unknown Source) at javax.swing.plaf.basic.BasicDirectoryModel$LoadFilesThread.run(Unknown Source) Java -version says: java version "1.6.0_20" Java(TM) SE Runtime Environment (build 1.6.0_20-b02) Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing) And the thread I found here says I should downgrade the Java version. Should I follow their advice, or is there something I could have done wrong?

  • close long poll connection, jQuery-ajax

    - by MyGGaN
    Background I use a Tornado-like server with support for long-polls. Each web pages a user clicks around to sets up a long poll to the server like this: $.ajax({ type: 'GET', url: "/mylongpollurl/", dataType: 'application/json', success: function(json) { // I do stuff here }, error: function(xhr, errText, ex) { // If timeout I send a new long-poll request } }); Problem I will now rely on data that I get from Fiddler monitoring all requests made from my browser (FF at the moment). Page 1 is loaded and the long poll request is made, now idling at server side. I click a link to page 2 and that page is loaded and setting up a long poll request, BUT the long poll request from page 1 is still idling at server side (according to Fiddler). This means that I will stack all long poll calls when clicking around the page, thus end up with lots of active connections on the server (or are they maybe sharing connection?) My thoughts - As it's a Tornado-like server (using epoll) it can handle quite a lot of connections. But this fact is not to exploit in my opinion. What I mean is that I prefer not to have a timeout on the server for this case (were the client disappears). - I know those stand alone pages better uses a common head and only swap content via ajax calls but this design we use today was not my call... - The best way to solve this would probably be to have the connection reused (hard to pull off I think) or closed as soon as the browser leaves the page (you click to another page). Thanks -- MyGGaN

  • Is this a good implementation of DefaultHttpClient and ThreadSafeClientConnManager in Android?

    - by johnrock
    In my Android app I am sharing one httpclient for all activities/threads. All requests are made by callling getHttpClient().execute(httpget) or getHttpClient().execute(httppost). Is this implementation complete/correct and safe for multiple threads? Is there anything else missing i.e. Do I have to worry about releasing connections at all? private static HttpClient httpclient ; public static HttpClient getHttpClient() { if(httpclient == null){ return getHttpClientNew(); } else{ return httpclient; } } public static synchronized HttpClient getHttpClientNew() { HttpParams params = new BasicHttpParams(); ConnManagerParams.setMaxTotalConnections(params, 100); HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); HttpProtocolParams.setContentCharset(params, "UTF_8"); HttpProtocolParams.setUseExpectContinue(params, false); HttpConnectionParams.setConnectionTimeout(params, 10000); HttpConnectionParams.setSoTimeout(params, 10000); SchemeRegistry schemeRegistry = new SchemeRegistry(); schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80)); ClientConnectionManager cm = new ThreadSafeClientConnManager(params, schemeRegistry); httpclient = new DefaultHttpClient(cm, params); return httpclient; } This is an example of how the httpclient is used: private void update() { HttpGet httpget = new HttpGet(URL); httpget.setHeader(USER_AGENT, userAgent); httpget.setHeader(CONTENT_TYPE, MGUtils.APP_XML); HttpResponse response; try { response = getHttpClient().execute(httpget); HttpEntity entity = response.getEntity(); if (entity != null) { // parse stuff } } catch (Exception e) { } }

  • Git subtree not properly using .gitignore when doing a partial clone

    - by D W
    I am a graduate student with many scripts, bibliography data in bibtex, thesis draft in latex, presentations in open office, posters in scribus, and figures and result data. I would like to put everything in one project under version control. Then when I need to work on a portion such as the bibliography data, I would like to check that subdirectory out, modify it as necessary and merge it back.I would like the ability to check out one version to my home computer, and a different one to my work computer and make changes to each independently and eventually merge them back. I would also like to be able to check out a piece of code from this big project and import it with versioning into a separate project. If I may changes I'd like to be able to merge them back to the original project. Based on my understanding git subtree can do this. http://github.com/apenwarr/git-subtree There is an example that is along the lines of what I'm trying to do at: http://psionides.jogger.pl/2010/02/04/sharing-code-between-projects-with-git-subtree/ Say the trunk of my project contained the directories: (bib bin cfg data fig src todo). When I use git subtree split -P bib -b export git checkout export I get a the bib directory, plus all files that should have been ignored or considered binary based on .gitignore such as the src directory and everything in it that ends in a tilde or the ./data directory. dwickrama@DWwork:~/research/trunk$ ls * -r biblography.bib JabRef src: script1.sh~ README~ script2.sh~ script3.sh~ script4.R~ script5.awk~ script5.py~ cfg: cfgFile1.ini~ cfgFile2.ini~ cfgFile3.ini~ bin: bigBinaryPackage1 bigBinaryPackage2 dwickrama@DWwork:~/research/trunk$ My .gitignore file is as follows: *.doc diff=word *.tex diff=tex *.bib diff=bibtex *.py diff=python *.eps binary *.jpg binary *.png binary ./bin/* binary *~ How do I prevent this?

  • Web application development platform recommendation

    - by TK.Maxi
    Hi all I did a year's worth of Pascal, Visual Basic and C++ 15 years ago, so suffice it to say that I'm a complete n00b & lamer when it comes to this. I really do hope that this question doesn't canned, but if it does, please be so kind as to point me in the direction of where it should be posted. I have an idea, like so many others, for a web app. I don't necessarily have the capital to outsource the development of the app right now, and I probably wouldn't want to, since non-disclosure agreements can be expensive to enforce, especially in this day and age of intercontinental outsourcing. I need the app to be usable on any mobile device (eventually), primarily on the major mobile platforms at first, on the web, (pc/mac/*ix) obviously, on mobile web browsers like opera mobile, etc. I envisage the app interacting with the major social networks like fb, orkut, msn im, twitter, et al in a way where friend's are messaged and/or wall posted, a message is posted to the users wall. Geo-location functionality is a plus, considering the service/app can be location sensitive in two ways, 1, the immediate location of the user, 2. the desired location of the user. I'd like to incorporate OpenID sign on, and the flip-side, the service will require that people (service providers) list their specialities/specialisations/interests/areas of expertise, so that matches to user requests can be made by the service, while users' requests are posted into the web universe. I've probably described a glut of apps out there, but I'd appreciate feedback on the sort of platform that I should look at using, be it hosted on something like Google's app engine, or written in android friendly code, or whatever. I'm a firm believer in herd mentality, especially at the start of a project that I have very little experience in. The more opinions, the merrier! I can't get very much more specific, since that would give the idea away. Thanks for your time and I look forward to hearing from wise and experienced and the fresh and innovative alike. Thanks

  • R and version control for the solo data analyst

    - by Jeromy Anglim
    Many data analysts that I respect use version control. For example: http://github.com/hadley/ See comments on http://permut.wordpress.com/2010/04/21/revision-control-statistics-bleg/ However, I'm evaluating whether adopting a version control system such as git would be worthwhile. A brief overview: I'm a social scientist who uses R to analyse data for research publications. I don't currently produce R packages. My R code for a project typically includes a few thousand lines of code for data input, cleaning, manipulation, analyses, and output generation. Publications are typically written using LaTeX. With regards to version control there are many benefits which I have read about, yet they seem to be less relevant to the solo data analyst. Backup: I have a backup system already in place. Forking and rewinding: I've never felt the need to do this, but I can see how it could be useful (e.g., you are preparing multiple journal articles based on the same dataset; you are preparing a report that is updated monthly, etc) Collaboration: Most of the time I am analysing data myself, thus, I woudln't get the collaboration benefits of version control. There are also several potential costs involved with adopting version control: Time to evaluate and learn a version control system A possible increase in complexity over my current file management system However, I still have the feeling that I'm missing something. General guides on version control seem to be addressed more towards computer scientists than data analysts. Thus, specifically in relation to data analysts in circumstances similar to those listed above: Is version control worth the effort? What are the main pros and cons of adopting version control? What is a good strategy for getting started with version control for data analysis with R (e.g., examples, workflow ideas, software, links to guides)?

  • How to share session cookies between Internet Explorer and an ActiveX components hosted in a webpage

    - by jerem
    I am currently working on a .Net application which makes HTTP requests to some web applications hosted on a IIS server. The application is deployed through ClickOnce and is working fine on simple networks architectures. One of our customers has a very complex network involving a custom authentication server on which the user has first to log himself in order to be authenticated and get access to other applications on this network. Once authenticated on this server, a session cookie is created and sent to the user. Every time the user then makes a request on a secured server of the network, this cookie is checked to grant access to the user. If this cookie is not sent with the request, the user is redirected to the login page. The only browser used is Internet Explorer. This cookie cannot be accessed from our .net application since it is executed in another process than the Internet Explorer process which was used to log the user in, and thus is not sent with our requests, which cannot be completed since the server redirects every of our requests to the login page. I had a look at embedding my application into Internet Explorer by making the main control COM visible and creating it on an HTML page with an tag. It is working properly, however the sessions cookies set earlier in the browser are not sent when the ActiveX control makes web requests. I was hoping this sharing of the session information would be automatic (although I didn't really believe it). So my questions are : Is it possible to have access to this cookie in the embedded ActiveX? How? Does it make a difference to use a .Net COM-interop component instead of a "true" ActiveX control? Also, are there specific security words to describe this kind of behaviors (given that I am not an expert at all on security topics, this lack of proper terminology makes it a lot harder to find the needed resources)? My goal is to have my application's requests look the same from the requests made by the host browser's requests, and I thought that embedding the application as an ActiveX control into the browser was the only way to achieve this, however any suggestion on another to do this is welcome.

  • Android SDK fails to install

    - by Paul Breed
    When I try to install the android SDK it fails to install. My OS is Windows XP I just downloaded and installed Java JDK 1.6 Java -version from the command line returns: http://stackoverflow.com/questions/ask java version "1.6.0_17" Java(TM) SE Runtime Environment (build 1.6.0_17-b04) Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode, sharing) My environment vars have: JAVA_HOME=c:\progra~1\java\jdk1.6.0_11 I downloaded android-sdk-r04-windows.zip I unziped it in V:\AndroidInstall\ When I go to the V:\androindinstall\android-sdk-windows and type "SDK Install.exe" nothing happens... If I go this from graph When I do this from a graphical file viewer I get a quick flash that looks like a command line window and nothing.... When I try to run android list targets from the tool directory I get: Error: Error parsing the sdk. Error: V:\androindinstall\android-sdk-windows\platforms is missing. Error: Unable to parse SDK content. So the basic install setup is not happening. Additional clues: I have a G1 and Android 1.0 was running on this machine. (Almost a year ago) I've updated my G1 to 1.6 so I thought I'd update my SDK before starting new development. When I tried to upgrade it tried and then died as the "directory was in use" So I cleaned out all the android directories, rebooted and redownloaded everythign from scratch. Now it won't run at all. I've clearly got something in an unhappy state, but I've cleaned up all the directories and no remanants seem to be running I've rebooted.... I've missed somethign I just can't figure out what. Paul

  • issues make a persistent object in Objective C

    - by oden
    Attempting to make a NSObject called 'Person' that will hold the login details for my application (nothing to fancy). The app is made of a navigation controller with multiple table views but I am having issues sharing the Person object around. Attempted to create a static object like this: + (Person *)sharedInstance { static Person *sharedInstance; @synchronized(self) { if(!sharedInstance) sharedInstance = [[Person alloc] init]; return sharedInstance; } return nil; } And here is the header // Person.h #import <Foundation/Foundation.h> @interface Person : NSObject { NSString *fullName; NSString *firstName; NSString *lastName; NSString *mobileNumber; NSString *userPassword; } @property(nonatomic, retain) NSString *fullName; @property(nonatomic, retain) NSString *firstName; @property(nonatomic, retain) NSString *lastName; @property(nonatomic, retain) NSString *mobileNumber; @property(nonatomic, retain) NSString *userPassword; + (Person *)sharedInstance; -(BOOL) setName:(NSString*) fname; -(BOOL) setMob:(NSString*) mnum; -(BOOL) setPass:(NSString*) pwd; @end This object setters and getters are needed in different parts of the application. I have been attempting to access them like this Person * ThePerson = [[Person alloc] init]; ThePerson = nil; NSString * PersonsName; PersonsName = [[Person sharedInstance] firstName]; Everything works well at the login screen but it dies at the next use. usually EXC_BAD_ACCESS (eek!). Clearly I am doing something very wrong here. Is there an easier way to share objects between different a number view controllers (both coded and xib)?

  • Python progression path - From apprentice to guru

    - by Morlock
    Hi all, I've been learning, working, and playing with Python for a year and a half now. As a biologist slowly making the turn to bio-informatics, this language has been a the very core of all the major contributions I have made in the lab. (bash and R scripts have helped some too. My C++ capabilities are very not functional yet). I more or less fell in love with the way Python permits me to express beautiful solutions and also with the semantics of the language that allows such a natural flow from thoughts to workable code. What I would like to know from you is your answer to a kind of question I have seldom seen in this or other forums. Let me sum up what I do NOT want to ask first ;) I don't want to know how to QUICKLY learn Python Nor do I want to find out the best way to get acquainted with the language Finally, I don't want to know a 'one trick that does it all' approach. What I do want to know your opinion about, is: What are the steps YOU would recommend to a Python journeyman, from apprenticeship to guru status (feel free to stop wherever your expertise dictates it), in order that one IMPROVES CONSTANTLY, becoming a better and better Python coder, one step at a time. The kind of answers I would enjoy (but feel free to surprise the readership :P ), is formatted more or less like this: Read this (eg: python tutorial), pay attention to that kind of details Code for so manytime/problems/lines of code Then, read this (eg: this or that book), but this time, pay attention to this Tackle a few real-life problems Then, proceed to reading Y. Be sure to grasp these concepts Code for X time Come back to such and such basics or move further to... (you get the point :) This process depicts an iterative Learn/Code cycle, and I really care about knowing your opinion on what exactly one should pay attention to, at various stages, in order to progress CONSTANTLY (with due efforts, of course). If you come from a specific field of expertise, discuss the path you see as appropriate in this field. Thanks a lot for sharing your opinions and good Python coding!

  • Thrift,.NET,Cassandra - Is this is right combination?

    - by Vadi
    I've been evaluating technology stack for developing a social network based application. Below are the stack I think could well suitable for this application type of application: GUI -- ASP.NET MVC, Flash (Flex) Business Services -- Thrift based services One of the advantage of using Thrift is to solve scaling problems that will come in future when the user base increases rapidly. All the business logic can be exposed as a services using REST,JSON etc., This also allows us to go with C++ or Erlang based services when situation demands. Database -- mySQL, CasSandara mySQL can be used for storing the data which needs to be persisted. Cassandara will be used for storing global identifiers to the persisted data. Since Cassandara is also very good at scaling by introducing more nodes this will leverage Thrift based services as well. And also there is native support between Cassandara and Thrift Cache Server -- Memcached Any requests from Business Services will only talk to Memcached if any non-dirty data is required, otherwise there will be some background jobs that will invalidate the cache from database. The question is: Is the Thrift which is open-sourced one is production-ready? Is it the right stack for services layer to choose when the application (GUI) is primarily gets developed in ASP.NET and DB is mysql? Is there any other caveats that anyone here experienced? One of the main objective behind this stack is to easily scale up with more nodes and also this helps us to use Linux boxes, it will reduce our cost significantly Thoughts please ..

  • Android Share - Facebook SDK - ShareActionProvider

    - by Vlasto Benny Lava
    I am trying to implement sharing a simple string inside my application. Obviously everything other than Facebook works. As far as I know, now I have to use their Facebook SDK to post statuses on a wall. However, if I do implement it using their SDK, is there a way to have it incorporated into the chooser (default or ShareActionProvider) and somehow override it and insert the Facebook SDK's implementation? Or do I have to create a dedicated button? //EDIT package com.example.shareactionproviderdemo; import android.app.Activity; import android.content.Intent; import android.os.Bundle; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Intent sharingIntent = new Intent(Intent.ACTION_SEND); sharingIntent.setType("text/plain"); sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Test message"); startActivity(Intent.createChooser(sharingIntent, "Share using")); } }

  • WCF - Increase ReaderQuoatas on REST service

    - by Christo Fur
    I have a WCF REST Service which accepts a JSON string One of the parameters is a large string of numbers This causes the following error - which is visible by tracing and using SVC Trace Viewer There was an error deserializing the object of type CarConfiguration. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Now I've read all sorts of articles advising how to rectify this All of them recommend increasing various config settings on the server and client e.g. http://stackoverflow.com/questions/65452/error-serializing-string-in-webservice-call http://bloggingabout.net/blogs/ramon/archive/2008/08/20/wcf-and-large-messages.aspx http://social.msdn.microsoft.com/Forums/en/wcf/thread/f570823a-8581-45ba-8b0b-ab0c7d7fcae1 So my config file looks like this <webHttpBinding> <binding name="webBinding" maxBufferSize="5242880" maxReceivedMessageSize="5242880" > <readerQuotas maxDepth="5242880" maxStringContentLength="5242880" maxArrayLength="5242880" maxBytesPerRead="5242880" maxNameTableCharCount="5242880"/> </binding> </webHttpBinding> ... ... ... <endpoint address="/" binding="webHttpBinding" bindingConfiguration="webBinding" My problem is that I can change this on the server, but there are no WCF config settings on the client as its a REST service and I'm just making a http request using the WebClient object any ideas?

  • Restarting explorer from a batch file only opens an explorer window

    - by Ben Hooper
    In one part of a batch file (kind of), I need to restart Explorer. I use the following method to accomplish this: taskkill /f /im explorer.exe >nul explorer.exe :: I have also tried: %winDir%\explorer.exe :: start %winDir%\explorer.exe :: start /b %winDir%\explorer.exe :: start /d %winDir%\explorer.exe (as suggested by panda-34) :: :: I've even tried delaying the above commands with: ping localhost -n 11 >nul Then this happens: explorer.exe is successfully terminated (denoted by the lack of taskbar and desktop) An explorer window opens, which I am left with indefinitely (see Image 1) I can only then restart explorer by manually starting a new process from Task Manager (Win + R doesn't respond), even though explorer.exe is actually already in the process list, strangely enough.. (see Image 2)   Now, I say "kind of" as I'm running the batch file from a self-executing SFX archive, created with WinRAR. When executed, the contents of the archive are extracted to %temp% and a user-defined bootstrapper (in this case, my batch file) is run upon successful extraction. The strangest thing about it, though, is that if you manually extract the contents of the archive and run the batch file then explorer restarts correctly. It only ever glitches when called from an SFX. I'm experiencing this glitch on Windows 7 x64.   Link to an SFX archive demonstrating this, if anyone wants it: https://dl.dropbox.com/u/27573003/Social%20Distribution/restart-explorer.exe Image 1: Image 2:

  • Enterprise SSO & Identity management / recommendations

    - by Maxim Veksler
    Hello Friends, We've discussed SSO before. I would like to re-enhance the conversation with defined requirements, taking into consideration recent new developments. In the past week I've been doing market research looking for answers to the following key issues: The project should should be: Requirements SSO solution for web applications. Integrates into existing developed products. has Policy based password security (Length, Complexity, Duration and co) Security Policy can be managed using a web interface. Customizable user interface (the password prompt and co. screens). Highly available (99.9%) Scalable. Runs on Red Hat Linux. Nice to have Contains user Groups & Roles. Written in Java. Free Software (open source) solution. None of the solutions came up so far are "killer choice" which leads me to think I will be tooling several projects (OWASP, AcegiSecurity + X??) hence this discussion. We are ISV delivering front-end & backend application suite. The frontend is broken into several modules which should act as autonomous unit, from client point of view he uses the "application" - which leads to this discussion regrading SSO. I would appreciate people sharing their experience & ideas regarding the appropriete solutions. Some solutions are interesting CAS Sun OpenSSO Enterprise JBoss Identity IDM JOSSO Tivoli Access Manager for Enterprise Single Sign-On Or more generally speaking this list Thank you, Maxim.

  • Bing maps silverlight control pushpin scaling problems.

    - by Rares Musina
    Baiscally my problem is that i've adapted a piece of code found here http://social.msdn.microsoft.com/Forums/en-US/vemapcontroldev/thread/62e70670-f306-4bb7-8684-549979af91c1 which does exactly what I want it to do, that is scale some pushpin images according to the map's zoom level. The only problem is that I've adapted this code to run with the bing maps silverlight control (not virtual earth like in the original example) and now the images scale correclty, but they are repositioned and only reach the desired position when my zoom level is maximum. Any idea why? Help will be greatly appreciated :) Modified code below: var layer = new MapLayer(); map.AddChild(layer); //Sydney layer.AddChild(new Pin { ImageSource = new BitmapImage(new Uri("pin.png", UriKind.Relative)), MapInstance = map }, new Location(-33.86643, 151.2062), PositionMethod.Center); becomes something like layer.AddChild(new Pin { ImageSource = new BitmapImage(new Uri("pin.png", UriKind.Relative)), MapInstance = map }, new Location(-33.92485, 18.43883), PositionOrigin.BottomCenter); I am assuming it has something to do with a different way in which bing maps anchors its UIelements. Details on that are also very userful. Thank you!

  • nth ugly number

    - by Anil Katti
    Numbers whose only prime factors are 2, 3 or 5 are called ugly numbers. Example: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, ... 1 can be considered as 2^0. I am working on finding nth ugly number. Note that these numbers are extremely sparsely distributed as n gets large. I wrote a trivial program that computes if a given number is ugly or not. For n 500 - it became super slow. I tried using memoization - observation: ugly_number * 2, ugly_number * 3, ugly_number * 5 are all ugly. Even with that it is slow. I tried using some properties of log - since that will reduce this problem from multiplication to addition - but, not much luck yet. Thought of sharing this with you all. Any interesting ideas? Using a concept similar to "Sieve of Eratosthenes" (thanks Anon) for (int i(2), uglyCount(0); ; i++) { if (i % 2 == 0) continue; if (i % 3 == 0) continue; if (i % 5 == 0) continue; uglyCount++; if (uglyCount == n - 1) break; } i is the nth ugly number. Even this is pretty slow. I am trying to find 1500th ugly number.

  • Linq-to-sql Compiled Query returns object NOT belonging to submitted DataContext ?

    Compiled query: public static class Machines { public static readonly Func<OperationalDataContext, short, Machine> QueryMachineById = CompiledQuery.Compile((OperationalDataContext db, short machineID) => db.Machines.Where(m => m.MachineID == machineID).SingleOrDefault() ); public static Machine GetMachineById(IUnitOfWork unitOfWork, short id) { Machine machine; // Old code (working) //var machineRepository = unitOfWork.GetRepository<Machine>(); //machine = machineRepository.Find(m => m.MachineID == id).SingleOrDefault(); // New code (making problems) machine = QueryMachineById(unitOfWork.DataContext, id); return machine; } It looks like compiled query is returning result from another data context [TestMethod] public void GetMachinesTest() { using (var unitOfWork = IoC.Get<IUnitOfWork>()) { // Compile Query var machine = Machines.GetMachineById(unitOfWork, 3); } using (var unitOfWork = IoC.Get<IUnitOfWork>()) { var machineRepository = unitOfWork.GetRepository<Machine>(); // Get From Repository var machineFromRepository = machineRepository.Find(m => m.MachineID == 2).SingleOrDefault(); var machine = Machines.GetMachineById(unitOfWork, 2); VerifyHuskyHostMachine(machineFromRepository, 2, "Machine 2", "222222", "H400RS", "MachineIconB.xaml", false, true, LicenseType.Licensed, InterfaceType.HuskyHostV2, "10.0.97.2:8080", "10.0.97.2", 8080, "4.0"); VerifyHuskyHostMachine(machine, 2, "Machine 2", "222222", "H400RS", "MachineIconB.xaml", false, true, LicenseType.Licensed, InterfaceType.HuskyHostV2, "10.0.97.2:8080", "10.0.97.2", 8080, "4.0"); Assert.AreSame(machineFromRepository, machine); // FAIL } } If I run other (complex) unit tests I'm getting as expected: An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext.

  • Comparing objects with IDispatch to get main frame only (BHO)

    - by shaimagz
    I don't know if anyone familiar with BHO (Browser Helper Object), but an expert in c++ can help me too. In my BHO I want to run the OnDocumentComplete() function only on the main frame - the first container and not all the Iframes inside the current page. (an alternative is to put some code only when this is the main frame). I can't find how to track when is it the main frame that being populated. After searching in google I found out that each frame has "IDispatch* pDisp", and I have to compare it with a pointer to the first one. This is the main function: STDMETHODIMP Browsarity::SetSite(IUnknown* pUnkSite) { if (pUnkSite != NULL) { // Cache the pointer to IWebBrowser2. HRESULT hr = pUnkSite->QueryInterface(IID_IWebBrowser2, (void **)&m_spWebBrowser); if (SUCCEEDED(hr)) { // Register to sink events from DWebBrowserEvents2. hr = DispEventAdvise(m_spWebBrowser); if (SUCCEEDED(hr)) { m_fAdvised = TRUE; } } } else { // Unregister event sink. if (m_fAdvised) { DispEventUnadvise(m_spWebBrowser); m_fAdvised = FALSE; } // Release cached pointers and other resources here. m_spWebBrowser.Release(); } // Call base class implementation. return IObjectWithSiteImpl<Browsarity>::SetSite(pUnkSite); } This is where I want to be aware whether its the main window(frame) or not: void STDMETHODCALLTYPE Browsarity::OnDocumentComplete(IDispatch *pDisp, VARIANT *pvarURL) { // as you can see, this function get the IDispatch *pDisp which is unique to every frame. //some code } I asked this question on Microsoft forum and I got an answer without explaining how to actually implement that: http://social.msdn.microsoft.com/Forums/en-US/ieextensiondevelopment/thread/7c433bfa-30d7-42db-980a-70e62640184c

  • Why does Facebook iOS dialog for feed publish disappear after login?

    - by Mason G. Zhwiti
    I'm trying to use the Facebook iOS "feed" dialog call to allow my app's user to share something on their Facebook wall. When the facebook app is not installed, it attempts to let them authenticate within the app (presumably using a web view). The issue is that this dialog just disappears once they authenticate. I was expecting the web view to return to the "feed" sharing view. How do I detect that they authenticated so that I can re-open the feed dialog? I've added fbDidLogin to my app delegate, but it's not being called. (I wasn't sure if this would normally be called or not, but I read several people recommending this.) SBJSON *jsonWriter = [SBJSON new]; // The action links to be shown with the post in the feed NSArray* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys: @"More Videos",@"name",@"http://www.example.com/",@"link", nil], nil]; NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks]; NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: @"Test Caption", @"caption", @"Test Description", @"description", @"https://s3.amazonaws.com/example/images/test.png", @"source", self.video.blogLink, @"link", @"01234567890123", @"app_id", actionLinksStr, @"actions", nil]; [delegate facebook].sessionDelegate = delegate; [[delegate facebook] dialog:@"feed" andParams:params andDelegate:self];

  • How to explain to users the advantages of dumb primary key?

    - by Hao
    Primary key attractiveness I have a boss(and also users) that wants primary key to be sophisticated/smart/attractive control number(sort of like Social Security number, or credit card number format) I just padded the primary key(in Views) with zeroes to appease their desire to make the control number sophisticated,smart and attractive. But they wanted it as: first 2 digits as client code, then 4 digits as year year, then last 4 digits as transaction number on that client on a given year, then reset the transaction number of client to 1 when next year flows. Each client's transaction starts with 1. e.g. WM20090001, WM20090002, BB2009001, WM20100001, BB20100001 But as I wanted to make things as simple as possible, I forgo embedding their suggested smartness in primary key, I just keep the primary key auto increments regardless of client and year. But to make it not dull-looking(they really are adamant to make the primary key as smart control number), I made the primary key appears to them smart, on view query, I put the client code and four digit year code on front of the eight-zero padded autoincrement key, i.e. WM200900000001. Sort of slug-like information on autoincremented primary key. Keeping primary key autoincrement regardless of any other information, we are able keep other potential side effects problem when they edit a record, for example, if they made a mistake of entering the transaction on WM, then they edit the client code to BB, if we use smart primary key, the primary keys of WM customer will have gaps in their control number. Or worse yet, instead of letting the control numbers have gaps/holes, the user will request that subsequent records of that gap should shift up to that gap and have their subsequent primary keys re-adjust(decremented). How do you deal with these user requests(reasonable or otherwise)? Do you yield to their request? Or just continue using dumb primary key and explain them the repercussions of having a very smart/sophisticated primary key and educate them the significant advantages of having a dumb primary key? P.S. quotable quote(http://articles.techrepublic.com.com/5100-10878_11-1044961.html): "If you hold your tongue the first time users ask what is for them a reasonable request, things will work a lot better in the end."
