• Configuring IoC container from modules/plug-ins ?

  - by rouen

  Hi guys, i am in big dilema.. I am working on highly modular web app in ASP.NET MVC 2 (in fact, core will be super lightweight, all work on modules/plugins). I found MEF pretty useful for modules discovery, but i dont want to us it as IoC container. There is pretty good chance that I will need advanced features of "true" IoC container, so I would like to use Unity. And here is the problem : how to allow modules to configure container (programatically) = register their own types (mvc controllers, custom implementations of services...) at application start without making hard dependency on Unity in all modules ? I know about Common Service Locator project, and it seems pretty good, but this interface co container only allows resolving types, not registering them (afaik). I really hope you can understand my point, I know my english is terrible (I am from non english speaking country :) Thanks a lot !

• How to access a variable in other class?

  - by Christine

  Hi! I've problem regarding GUI with one Menu and one Order Class. I've created a variable to store how many items have been selected in the Menu Class. private int totalSelected; The var totalSelected is live updated. It can be changed anytime depending on actionPerformed() function.(Exp: totalSelected will add up all the selected items) In the Order Class, how can I access to the live update variable totalSelected in order to retrieve the live update value? When I invoke getTotalSelected() function inside the Menu Class, I will only obtain a 0 value. Thanks for your help ^^! Please allow me to specify my question clearer. public class MenuTab extends JPanel { private JLabel display; private int totalSelected; public MenuTab() { .... } } public getTotalSelected(){ return totalSelected; } private class SelectedListener implements ActionListener { public void actionPerformed() { ....... //Assume that totalSelected has been updated! display = new JLabel("Total: " + totalSelected); // OK to display totalSelected live value here. } } // A new class is the confirmation of order public class OrderConfirmedTab extends JPanel{ private JLabel displayTotal; private MenuTab order = new MenuTab(); public OrderConfirmedTab() { ...... int totalSelected = order.getTotalSelected(); displayTotal = new JLabel("Total: " + totalSelected); // Problem to display totalSelected live value here. // Will obtain 0; // How can I obtain the live updated value from class MenuTab? Thanks! } }

• Graph diffing and versioning tool

  - by hashable

  I am working with a team that edits large DAGs represented as single files. Currently we are unable to work with multiple users concurrently modifying the DAG. Is there a tool (somewhat like the Eclipse SVN plugin) that can do do revision control on the file (manage timestamps/revision stamps) to identify incoming/outgoing/conflicting changes (Node/Link insertion/deletion/modification) and merge changes just like programmers do with source code files? The system should be able to do dependency management also. E.g. an incoming Link must not be accepted when one of the two Nodes is absent. That is, it should not "break" the existing DAG by allowing partial updates. If there is a framework to do this using generic "Node" and "Link" interfaces? Note: I am aware of Protege and its plugins. They currently do not satisfy my requirements.

• What is a good way to sync code files between computer?

  - by erotsppa

  I have a need to code from two computers during the week. What is the best way to sync the two computers (mac)? I've started using source control, like SVN. It works pretty good, except sometimes I check in code that I want to sync but they don't compile and it interferes with other people on the team working on the same project. I don't want to use branch. It wouldn't make sense to branch every night when I head home from office.

• Programming style: should you return early if a guard condition is not satisfied?

  - by John Topley

  One thing I've sometimes wondered is which is the better style out of the two shown below (if any)? Is it better to return immediately if a guard condition hasn't been satisfied, or should you only do the other stuff if the guard condition is satisfied? For the sake of argument, please assume that the guard condition is a simple test that returns a boolean, such as checking to see if an element is in a collection, rather than something that might affect the control flow by throwing an exception. // Style 1 public SomeType aMethod() { SomeType result = null; if (!guardCondition()) { return result; } doStuffToResult(result); doMoreStuffToResult(result); return result; } // Style 2 public SomeType aMethod() { SomeType result = null; if (guardCondition()) { doStuffToResult(result); doMoreStuffToResult(result); } return result; }

• Python: Access dictionary value inside of tuple and sort quickly by dict value

  - by Aquat33nfan

  I know that wasn't clear. Here's what I'm doing specifically. I have my list of dictionaries here: dict = [{int=0, value=A}, {int=1, value=B}, ... n] and I want to take them in combinations, so I used itertools and it gave me a tuple (Well, okay it gave me a memory object that I then used enumerate on so I could loop over it and enumerate gave ma tuple): for (index, tuple) in enumerate(combinations(dict, 2)): and this is where I have my problem. I want to identify which of the two items in the combination has the bigger 'int' value and which has the smaller value and assign them to variables (I'm actually using more than 2 in the combination so I can't just say if tuple[0]['int'] tuple[1]['int'] and do the assignment because I'd have to list this out a bunch of times and that's hard to manage). I was going to assign each 'int' value to a variable, sort it in a list, index the 'int' value in the list by 1, 2, 3, 4, 5 ... etc., then go back and access the dictionary I wanted by the int value and then assign the dictionary to a variable so I knew which was bigger. But I have a big list and lists and variable assignments are resource intensive and this is taking a long time (I had only a little bit of that written and it was taking forever to run). So I was hoping someone knew a fast way to do this. I actually could list out every possible combination of assignmnets using the if/thens but it's just like 5 pages of if/thens and assignments and is hard to read and manage when I want to change it. You've probably gathered this, but I"m new at programming. thx

• Google Chrome does not honor cache-policy in page header if the page is displayed in a FRAME

  - by Tim

  No matter what I do: <meta http-equiv="Cache-Control" content="no-cache" /> <meta http-equiv="Expires" content="Fri, 30 Apr 2010 11:12:01 GMT" /> <meta http-equiv="Expires" content="0" /> <HTTP-EQUIV="PRAGMA" CONTENT="NO-STORE" /> Google Chrome does not reload any page according to the page's internal cache policy if the page is displayed in a frame. It is as though the meta tags are not even there. Google Chrome seems to be ignoring these tags. Since I've gotten answers to this question on other forums where the person responding has ignored the operative condition, I will repeat it: this behavior occurs when the page is displayed in a frame. I was using the latest released version and have since upgraded to 5.0.375.29 beta but the behavior is the same in both versions. Would someone please care to confirm one way or another the behavior you are seeing with framesets and the caching/expiration policies given in meta tags? Thanks

• Facebook offline access step-by-step

  - by Ben

  After searchinge litteraly 1 day on fb and google for an up-to-date and working way to do something seemingly simple: I am looking for a step-by-step explanation to get offline_access for a user for a facebook app and then using this (session key) to retrieve offline & not within a browser friends & profile data. Preferrably doing this in the Fb Java API. Thanks. And yes I did check the facebook wiki. Update: Anyone? this: http://www.facebook.com/authorize.php?api_key=<api-key>&v=1.0&ext_perm=offline_access gives me offline_Access, however how to retrieve the session_key? Why can't facebook just do simple documentation, I mean there are like 600 people working there? The seemingly same question: http://stackoverflow.com/questions/617043/getting-offlineaccess-to-work-with-facebook Does not answer how to retrieve the session key Edit: I am still stuck with that. I guess nobody really tried such a batch access out yet...

• Clarification of atomic memory access for different OSs

  - by murrekatt

  I'm currently porting a Windows C++ library to MacOS as a hobby project as a learning experience. I stumbled across some code using the Win Interlocked* functions and thus I've been trying to read up on the subject in general. Reading related questions here in SO, I understand there are different ways to do these operations depending on the OS. Interlocked* in Windows, OSAtomic* in MacOS and I also found that compilers have builtin (intrinsic) operations for this. After reading gcc builtin atomic memory access, I'm left wondering what is the difference between intrinsic and the OSAtomic* or Interlocked* ones? I mean, can I not choose between OSAtomic* or gcc builtin if I'm on MacOS when I use gcc? The same if I'd be on Windows using gcc. I also read that on Windows Interlocked* come as both inline and intrinsic versions. What to consider when choosing between intrinsic or inline? In general, are there multiple options on OSs what to use? Or is this again "it depends"? If so, what does it depend on? Thanks!

• Replacement for Hamachi for SVN access

  - by Piers

  My company has been using Hamachi to access our SVN repository for a number of years. We are a small yet widely distributed development team with each programmer in a different country working from home. The server is hosted by a non-techie in our central office. Hamachi is useful here since it has a GUI and supports remote management. This system worked well for a while, but recently I have moved to a country with poor internet speeds. Hamachi will no longer connect 99% of the time - instead I get a "Probing..." message that doesn't resolve. It's certain to be a latency issue, as the same laptop will connect without problems when I cross the border and connect using a different ISP with better speeds. So I really need to replace Hamachi with some other VPN/protocol that handles latency better. The techie managing the repository is not comfortable installing and configuring Apache or IIS, so it looks like HTTP is out. I tried to convince my boss to go for a web hosting company, but he doesn't trust a 3rd party with our source. Any other recommended options / experiences out there for accessing our SVN repos that would be as simple as Hamachi for setup; but be more tolerant of network latency issues?

• How to create project specific respository post-commit actions

  - by Pacifika

  Presently, we've got several main projects each in their own repository. We will have to version-control up to a dozen additional projects. VisualSVN recommends to create 1 respository for our company and then vc all projects inside that. It's a good practice to create one repository for the entire company or department and store all your projects in this repository. Creating separate repository for each project is not a good idea because in that case you will not be able to perform Subversion operations like copy, diff and merge cross-project. VisualSvn.com Currently we're using post-commit hooks to update the testing server with the latest commit and do other project specific actions (such as emailing certain people for one project but not for others) depending on which project has been committed. As post-commit runs for the whole repository, is this still possible in such a situation? How would I go about decerning which project has changes? filter folder structure?

• How to access valuestack objects within struts iterator?

  - by Monika Michael

  I have following code - <s:iterator value="reviews"> <img src="<s:property value="#request.restaurant.portalImage.url" />" /> <s:property value="user.firstName" /> <s:property value="user.lastName" /> <s:property value="rating" /> <s:property value="review" /> </s:iterator> reviews is a list of review objects which contain details of a review, such as rating and name of user. My problem is that i'm not able to access any of the objects present on the valuestack within the loop. Outside the loop <s:property value="#request.restaurant.portalImage.url" /> works correctly. But within the loop it prints null. AFAIK an iterator pushes it's collection on the valuestack so that all ognl expressions resolve against it. But I've used # which means I'm explicitly specifying the root object for resolution. Why is it still not working?

• How to redirect registry access of a dll loaded by my program

  - by dummzeuch

  I have got a dll that I load in my program which reads and writes its settings to the registry (hkcu). My program changes these settings prior to loading the dll so it uses the settings my program wants it to use which works fine. Unfortunately I need to run several instances of my program with different settings for the dll. Now the approach I have used so far no longer works reliably because it is possible for one instance of the program to overwrite the settings that another instance just wrote before the dll has a chance to read them. I haven't got the source of the dll in question and I cannot ask the programmer who wrote it to change it. One idea I had, was to hook registry access functions and redirect them to a different branch of the registry which is specific to the instance of my program (e.g. use the process id as part of the path). I think this should work but maybe you have got a different / more elegant. In case it matters: I am using Delphi 2007 for my program, the dll is probably written in C or C++.

• Permission denied to access property 'toString'

  - by Anders

  I'm trying to find a generic way of getting the name of Constructors. My goal is to create a Convention over configuration framework for KnockoutJS My idea is to iterate over all objects in the window and when I find the contructor i'm looking for then I can use the index to get the name of the contructor The code sofar (function() { constructors = {}; window.findConstructorName = function(instance) { var constructor = instance.constructor; var name = constructors[constructor]; if(name !== undefined) { return name; } var traversed = []; var nestedFind = function(root) { if(typeof root == "function" || traversed[root]) { return } traversed[root] = true; for(var index in root) { if(root[index] == constructor) { return index; } var found = nestedFind(root[index]); if(found !== undefined) { return found; } } } name = nestedFind(window); constructors[constructor] = name; return name; } })(); var MyApp = {}; MyApp.Foo = function() { }; var instance = new MyApp.Foo(); console.log(findConstructorName(instance)); The problem is that I get a Permission denied to access property 'toString' Exception, and i cant even try catch so see which object is causing the problem Fiddle http://jsfiddle.net/4ZwaV/

• Backing up locally modified and new source files

  - by eran

  I'm wondering how other programmers are backing up changes that are not under source control yet, be it new files or modified ones. I'm mostly referring to medium size jobs - hardly worth the effort of making a private branch, but taking more than a day to complete. This is not a vendor-specific question - I'd like to see if various products have different solutions to the problem. I'd appreciate answers referring to SVN and distributed SCCs, though. I'm mostly wondering about that latters (Mercurial, GIT etc.) - it's great that you have your own local repo, but do you back it up on a regular basis along with your source files? Note - I'm not asking about a general backup strategy. For that, we have IT. I'm seeking the best way to keep locally modified stuff backed-up before they are checked back into the main repo.

• CanCan polymorphic resource access problem

  - by Call 'naive' True

  Hi everybody, i don't quite understand how to restrict access to links in this particular case with CanCan. I always get "Edit" link displayed. So i believe the problem is in my incorrect definition of cancan methods(load_ and authorize_). I have CommentsController like that: class CommentsController < ApplicationController before_filter :authenticate_user! load_resource :instance_name => :commentable authorize_resource :article def index @commentable = find_commentable #loading our generic object end ...... private def find_commentable params.each { |name, value| if name =~ /(.+)_id$/ return $1.classify.constantize.includes(:comments => :karma).find(value) end } end end and i have in comments/index.html.erb following code that render file from other controller: <%= render :file => "#{get_commentable_partial_name(@commentable)}/show.html.erb", :collection => @commentable %> you can think about "#{get_commentable_partial_name(@commentable)}" like just "articles" in this case. Content of "articles/show.html.erb": <% if can? :update, @commentable %> <%= link_to 'Edit', edit_article_path(@commentable) %> | <% end %> my ability.rb: class Ability include CanCan::Ability def initialize(user) user ||= User.new # guest user if user.role? :admin can :manage, :all elsif user.role? :author can :read, [Article, Comment, Profile] can :update, Article, :user_id => user.id end end end relations with models is: class Comment < ActiveRecord::Base belongs_to :commentable, :polymorphic => true, :dependent => :destroy ... end class Article < ActiveRecord::Base has_many :comments, :as => :commentable, :dependent => :destroy ... end i have tried debug this issue like that user = User.first article = Article.first ability = Ability.new(user) ability.can?(:update, article) and i always get "= true" in ability check Note: user.role == author and article.user_id != user.id if you need more information please write thank's for your time && sorry for my english

• Experience with SVN vs. Team Foundation Server?

  - by bcwood

  A few months back my team switched our source control over to Subversion from Visual SourceSafe, and we haven't been happier. Recently I've been looking at Team Foundation Server, and at least on the surface, it seems very impressive. There is some great integration with Visual Studio, and lots of great tools for DBA's, testers, project managers, etc. The most obvious difference between these two products is price. It's hard to beat Subversion (free). Team Foundation Server is quite expensive, so the extra features would really have to kick Subversion in the pants. My question is: does anyone have practical experience with both? How do they compare, and is Team Foundation Server actually worth all the money?

• Sequential access to asynchronous sockets

  - by Lars A. Brekken

  I have a server that has several clients C1...Cn to each of which there is a TCP connection established. There are less than 10,000 clients. The message protocol is request/response based, where the server sends a request to a client and then the client sends a response. The server has several threads, T1...Tm, and each of these may send requests to any of the clients. I want to make sure that only one of these threads can send a request to a specific client at any one time, while the other threads wanting to send a request to the same client will have to wait. I do not want to block threads from sending requests to different clients at the same time. E.g. If T1 is sending a request to C3, another thread T2 should not be able to send anything to C3 until T1 has received its response. I was thinking of using a simple lock statement on the socket: lock (c3Socket) { // Send request to C3 // Get response from C3 } I am using asynchronous sockets, so I may have to use Monitor instead: Monitor.Enter(c3Socket); // Before calling .BeginReceive() And Monitor.Exit(c3Socket); // In .EndReceive I am worried about stuff going wrong and not letting go of the monitor and therefore blocking all access to a client. I'm thinking that my heartbeat thread could use Monitor.TryEnter() with a timeout and throw out sockets that it cannot get the monitor for. Would it make sense for me to make the Begin and End calls synchronous in order to be able to use the lock() statement? I know that I would be sacrificing concurrency for simplicity in this case, but it may be worth it. Am I overlooking anything here? Any input appreciated.

• Access Controller Context/ TempData from business objects

  - by thanikkal

  I am trying to build a session/tempdata provider that can be swapped. The default provider will work on top of asp.net mvc and it needed to access the .net mvc TempData from the business object class. I know the tempdata is available through the controller context, but i cant seem to find if that is exposed through HttpContext or something. I dont really want to pass the Controller context as an argument as that would dilute my interface definition since only asp.net based session provider needs this, other (using NoSQL DB etc) doesn't care about Controller Context. To clarify further, adding little more code here. my ISession interface look like this. and when this code goes to production, the session/tempdata is expected to work using NoSql db. But i also like to have another implementation that works on top of asp.net mvc session/tempdata for my dev testing etc. public interface ISession { T GetTempData<T>(string key); void PutTempData<T>(string key, T value); T GetSessiondata<T>(string key); void PutSessiondata<T>(string key, T value); }

• MVC 2 Beta DefaultControllerFactory with Areas

  - by stoto

  Why default factory WON'T return full name of the controllers (with namespaces)? I'm using Service Locator and autofac. using System.Web.Mvc; using Microsoft.Practices.ServiceLocation; namespace Application.Core.MVC { public override IController CreateController(System.Web.Routing.RequestContext requestContext, string **controllerName**) { return ServiceLocator.Current.GetInstance<IController>(controllerName); } } I had two home controllers (one under area Blog) http://localhost/Home http://localhost/Blog/Home controllerName return only "Home" without full qualified name for both in above code. This creates a problem when I try to regiser controllers' names for dependency injection. Here is how I register controllers right now according to this situation. Even this brings up the pages without exception. But When I access http://localhost/Home, both controllers invoked regardlessly. foreach (var tp in currentAssemblyControllersTypes) builder.Register(tp).FactoryScoped().Named(tp.Name.Replace("Controller", "")); Anyone can help?Thanks.

• Convert my aspx page to png image

  - by Izabela

  I am generating an aspx page which then I need to convert to png and store it somewhere. A similiar situation with mine was asked before here but got still no response. I tried also the code that the Swapnil Fegade has asked but the code is looping continually making request to loading page and no conversion is actually being done. I found some solutions on the web also but they require WebBrowser control which i understood can be used in windows form but i am building a web project. Can you give me any hint or suggest any article that shows a full example doing this task. Thank you guys in advance.

• Building out a well-structured service layer

  - by Chris Stewart

  First, I want to say that it has been awhile since I've gotten into the kind of detail I am at currently. Lately, I've been very much in the SharePoint world and my entire thought process was focused there for quite some time. I'm very glad to be creating databases again, writing "lower level" code to deal with data access, and so forth. I'm working on a very simple web application and taking the opportunity to reacquaint myself with the way I used to structure my projects and various layers of code. For instance, I might have created something like this the last time I went about building something basic from scratch: - MyProject/ -- Domain/ --- Impl/ ---- Person -- Model/ --- IPersonRepository --- Impl/ ---- PersonRepository : IPersonRepository -- Services --- IPersonService --- Impl/ ---- PersonService : IPersonService That would have been the project I did the real work in, and then referenced in the ASP.NET project. My approach was very much inspired by what I saw from the CodeCampServer project as at that time ASP.NET MVC was still very new and it was the only open project I could find actively being developed, and by solid people at that. What ways are you going about structuring your projects and code, when it comes to a general problem you're working on? Certainly various problems can put constraints on this, but assume it's a basic problem without specific needs that affect the structure and layout of your code.

• Hosted SVN - RepositoryHosting.com

  - by SVN User

  I'm currently reviewing repositoryhosting.com for possibly hosting our company code, however, I'm weary about pushing forward for a few reasons. First, if the company goes under, I have no assurance that I will have access to grab backups of the code prior. Secondly, their terms state this: "User agrees that Repository Hosting shall not be liable for any direct, indirect, incidental, special, consequential or exemplary damages, including but not limited to, damages for loss of profits, goodwill, use, data or other intangible losses resulting from the use of or inability to use the Service." Basically, I want to ensure that our data is safe. I understand that they do offsite backups and such, however, if there were to be a catastrophic loss of data that was their fault, would we be left with just a "sorry"? What about your thoughts on hosted svn and is it better to just continue to do it yourself?

• How to improve multi-threaded access to Cache (custom implementation)

  - by Andy

  I have a custom Cache implementation, which allows to cache TCacheable<TKey> descendants using LRU (Least Recently Used) cache replacement algorithm. Every time an element is accessed, it is bubbled up to the top of the LRU queue using the following synchronized function: // a single instance is created to handle all TCacheable<T> elements public class Cache() { private object syncQueue = new object(); private void topQueue(TCacheable<T> el) { lock (syncQueue) if (newest != el) { if (el.elder != null) el.elder.newer = el.newer; if (el.newer != null) el.newer.elder = el.elder; if (oldest == el) oldest = el.newer; if (oldest == null) oldest = el; if (newest != null) newest.newer = el; el.newer = null; el.elder = newest; newest = el; } } } The bottleneck in this function is the lock() operator, which limits cache access to just one thread at a time. Question: Is it possible to get rid of lock(syncQueue) in this function while still preserving the queue integrity?
