• How to use the LINQ where expression?

  - by NullReference

  I'm implementing the service \ repository pattern in a new project. I've got a base interface that looks like this. Everything works great until I need to use the GetMany method. I'm just not sure how to pass a LINQ expression into the GetMany method. For example how would I simply sort a list of objects of type name? nameRepository.GetMany( ? ) public interface IRepository<T> where T : class { void Add(T entity); void Update(T entity); void Delete(T entity); void Delete(Expression<Func<T, bool>> where); T GetById(long Id); T GetById(string Id); T Get(Expression<Func<T, bool>> where); IEnumerable<T> GetAll(); IEnumerable<T> GetMany(Expression<Func<T, bool>> where); } public virtual IEnumerable<T> GetMany(Expression<Func<T, bool>> where) { return dbset.Where(where).ToList(); }

  There's Active directory on windows 2000 advance server, I have a web server on Windows 2008 server Enterprise Edition, the following code works fine in Winsows 2003 server but when I installed Win 2008 server, it gives me the following error, the webserver is not subdomain of the AD server. but they have the same range IP address. A local error has occurred.\r\n"} System.Exception system.DirectoryServices.DirectoryServicesCOMException} I want to Authenticate Via AD from my webserver, I even test the port 389 and it was open(by telnet), I even added port 389 UDP and TCP to firewall of webserver to be sure it is open, even I turned the firewall off but nothing changed. I don't know what's wrong with Windows 2008 server that cannot run my code, I search Internet but I found nothing. any solution would be helpful.

• Is it possible to disable/bypass the login popup caused by mod_auth_ntlm_winbind (Single Sign On) an

  - by cvack

  I have an intranet on a remote Web server. This will be integrated with Active Directory on our local server. The web server is running Apache / Linux and the AD server is running Windows 2003. This is all done with VPN. Login to the intranet is conducted in two ways: 1. Users who are logged in to AD to be logged in automatically with SSO. 2. Users who are NOT logged in to AD to be logged in using a common login form. In order to auto login (SSO) I use mod_auth_ntlm_winbind. The problem here is that the users not logged in to AD will get a popup box where they must enter their DOMAIN/username + AD password. If I disable this popup, there is no way to get $_SERVER['REMOTE_USER'] Then my question: Is it possible to turn off this popup box and still get the REMOTE_USER? Or: If possible, can I use AJAX to check if http://my-intranet/auth returns 401 error (non-AD users). If so, do not go to the /auth folder.

• Double hashing passwords - client & server

  - by J. Stoever

  Hey, first, let me say, I'm not asking about things like md5(md5(..., there are already topics about it. My question is this: We allow our clients to store their passwords locally. Naturally, we don't want them stored in plan text, so we hmac them locally, before storing and/or sending. Now, this is fine, but if this is all we did, then the server would have the stored hmac, and since the client only needs to send the hmac, not the plain text password, an attacker could use the stored hashes from the server to access anyone's account (in the catastrophic scenario where someone would get such an access to the database, of course). So, our idea was to encode the password on the client once via hmac, send it to the server, and there encode it a second time via hmac and match it against the stored, two times hmac'ed password. This would ensure that: The client can store the password locally without having to store it as plain text The client can send the password without having to worry (too much) about other network parties The server can store the password without having to worry about someone stealing it from the server and using it to log in. Naturally, all the other things (strong passwords, double salt, etc) apply as well, but aren't really relevant to the question. The actual question is: does this sound like a solid security design ? Did we overlook any flaws with doing things this way ? Is there maybe a security pattern for something like this ?

• WIN32 Logon question

  - by Lalit_M

  We have developed a ASP.NET 3.5 web application with Web Server 2008 and has implemented a custom authentication solution using active directory as the credentials store. Our front end application uses a normal login form to capture the user name and password and leverages the Win32 LogonUser method to authenticate the user’s credentials. When we are calling the LogonUser method, we are using the LOGON32_LOGON_NETWORK as the logon type. The issue we have found is that user profile folders are being created under the C:\Users folder of the web server. The folder seems to be created when a new user who has never logged on before is logging in for the first time. As the number of new users logging into the application grows, disk space is shrinking due to the large number of new user folders getting created. I need to get the token back after the authentication (authenticated \ password locked \ wrong password ) its futher use and based on logic showing different web pages Has anyone seen this behavior with the Win32 LogonUser method? Please answer the following issue: Is it possible to disable this behavior to create the folder as taking 2.78 MB of space for every new user and it eating my disck space? I have tried LOGON32_LOGON_BATCH but it was giving an error 1385 in authentication user. For any solution related to LOGON32_LOGON_BATCH, can you please confirm if that will stop creating the folders at location C:\users. Also for any possible solution I need either I am able to disable the folder to be created at C:\user or Any other option to authenticated user which will not creat folders.

• F# How to tokenise user input: separating numbers, units, words?

  - by David White

  I am fairly new to F#, but have spent the last few weeks reading reference materials. I wish to process a user-supplied input string, identifying and separating the constituent elements. For example, for this input: XYZ Hotel: 6 nights at 220EUR / night plus 17.5% tax the output should resemble something like a list of tuples: [ ("XYZ", Word); ("Hotel:", Word); ("6", Number); ("nights", Word); ("at", Operator); ("220", Number); ("EUR", CurrencyCode); ("/", Operator); ("night", Word); ("plus", Operator); ("17.5", Number); ("%", PerCent); ("tax", Word) ] Since I'm dealing with user input, it could be anything. Thus, expecting users to comply with a grammar is out of the question. I want to identify the numbers (could be integers, floats, negative...), the units of measure (optional, but could include SI or Imperial physical units, currency codes, counts such as "night/s" in my example), mathematical operators (as math symbols or as words including "at" "per", "of", "discount", etc), and all other words. I have the impression that I should use active pattern matching -- is that correct? -- but I'm not exactly sure how to start. Any pointers to appropriate reference material or similar examples would be great.

• Project Naming Convention Feedback Please

  - by Sam Striano

  I am creating a ASP.NET MVC 3 application using Entity Framework 4. I am using the Repository/Service Pattern and was looking for feedback. I currently have the following: MVC Application (GTG.dll) GTG GTG.Controllers GTG.ViewModels Business POCO's (GTG.Business.dll) This contains all business objects (Customer, Order, Invoice, etc...) EF Model/Repositories (GTG.Data.dll) GTG.Business (GTG.Context.tt) I used the Entity POCO Generator Templates. GTG.Data.Repositories Service Layer (GTG.Data.Services.dll) GTG.Data.Services - Contains all of the service objects, one per aggregate root. The following is a little sample code: Controller Namespace Controllers Public Class HomeController Inherits System.Web.Mvc.Controller Function Index() As ActionResult Return View(New Models.HomeViewModel) End Function End Class End Namespace Model Namespace Models Public Class HomeViewModel Private _Service As CustomerService Public Property Customers As List(Of Customer) Public Sub New() _Service = New CustomerService _Customers = _Service.GetCustomersByBusinessName("Striano") End Sub End Class End Namespace Service Public Class CustomerService Private _Repository As ICustomerRepository Public Sub New() _Repository = New CustomerRepository End Sub Function GetCustomerByID(ByVal ID As Integer) As Customer Return _Repository.GetByID(ID) End Function Function GetCustomersByBusinessName(ByVal Name As String) As List(Of Customer) Return _Repository.Query(Function(x) x.CompanyName.StartsWith(Name)).ToList End Function End Class Repository Namespace Data.Repositories Public Class CustomerRepository Implements ICustomerRepository Public Sub Add(ByVal Entity As Business.Customer) Implements IRepository(Of Business.Customer).Add End Sub Public Sub Delete(ByVal Entity As Business.Customer) Implements IRepository(Of Business.Customer).Delete End Sub Public Function GetByID(ByVal ID As Integer) As Business.Customer Implements IRepository(Of Business.Customer).GetByID Using db As New GTGContainer Return db.Customers.FirstOrDefault(Function(x) x.ID = ID) End Using End Function Public Function Query(ByVal Predicate As System.Linq.Expressions.Expression(Of System.Func(Of Business.Customer, Boolean))) As System.Linq.IQueryable(Of Business.Customer) Implements IRepository(Of Business.Customer).Query Using db As New GTGContainer Return db.Customers.Where(Predicate) End Using End Function Public Sub Save(ByVal Entity As Business.Customer) Implements IRepository(Of Business.Customer).Save End Sub End Class End Namespace

• Store Business Rules in XML Document, Validate afterwards in Java, how?

  - by JavaPete

  Example XML Rules document: <user> <username> <not-null/> <capitals value="false"/> <max-length value="15"/> </username> <email> <not-null/> <isEmail/> <max-length value="40"/> </email> </user> How do I implement this? I'm starting from scratch, what I currently have is a User-class, and a UserController which saves the User object in de DB (through a Service-layer and Dao-layer), basic Spring MVC. I can't use Spring MVC Validation however in our Model-classes, I have to use an XML document so an Admin can change the rules I think I need a pattern which dynamically builds an algorithm based on what is provided by the XML Rules document, but I can't seem to think of anything other than a massive amount of if-statements. I also have nothing for the parsing yet and I'm not sure how I'm gonna (de)couple it from the actual implementation of the validation-process.

• Should Service Depend on Many Repositories, or Break Them Up?

  - by Josh Pollard

  I'm using a repository pattern for my data access. So I basically have a repository per table/class. My UI currently uses service classes to actually get things done, and these service classes wrap, and therefore depend on repositories. In many cases my services are only dependent upon one or two repositories, so things aren't too crazy. Unfortunately, one of my forms in the UI expects the user to enter data that will span five different tables. For this form I made a single service class that depends upon five repositories. Then the methods within the service for saving and loading the data call the appropriate methods on all of the corresponding repositories. As you can imagine, the save and load methods in this service are really big. Also, unit testing this service is getting really difficult because I have to setup so many fake repositories. Would it have been a better choice to break this single service apart into a few smaller services? It would put more code at the UI layer, but would make the services smaller and more testable.

• Given the presentation model pattern, is the view, presentation model, or model responsible for adding child views to an existing view at runtime?

  - by Ryan Taylor

  I am building a Flex 4 based application using the presentation model design pattern. This application will have several different components to it as shown in the image below. The MainView and DashboardView will always be visible and they each have corresponding presentation models and models as necessary. These views are easily created by declaring their MXML in the application root. <s:HGroup width="100%" height="100%"> <MainView width="75% height="100%"/> <DashboardView width="25%" height="100%"/> </s:HGroup> There will also be many WidgetViewN views that can be added to the DashboardView by the user at runtime through a simple drop down list. This will need to be accomplished via ActionScript. The drop down list should always show what WidgetViewN has already been added to the DashboardView. Therefore some state about which WidgetViewN's have been created needs to be stored. Since the list of available WidgetViewN and which ones are added to the DashboardView also need to be accessible from other components in the system I think this needs to be stored in a Model object. My understanding of the presentation model design pattern is that the view is very lean. It contains as close to zero logic as is practical. The view communicates/binds to the presentation model which contains all the necessary view logic. The presentation model is effectively an abstract representation of the view which supports low coupling and eases testability. The presentation model may have one or more models injected in in order to display the necessary information. The models themselves contain no view logic whatsoever. So I have a several questions around this design. Who should be responsible for creating the WidgetViewN components and adding these to the DashboardView? Is this the responsibility of the DashboardView, DashboardPresentationModel, DashboardModel or something else entirely? It seems like the DashboardPresentationModel would be responsible for creating/adding/removing any child views from it's display but how do you do this without passing in the DashboardView to the DashboardPresentationModel? The list of available and visible WidgetViewN components needs to be accessible to a few other components as well. Is it okay for a reference to a WidgetViewN to be stored/referenced in a model? Are there any good examples of the presentation model pattern online in Flex that also include creating child views at runtime?

• Is there a Design Pattern for preventing dangling references?

  - by iFreilicht

  I was thinking about a design for custom handles. The thought is to prevent clients from copying around large objects. Now a regular handle class would probably suffice for that, but it doesn't solve the "dangling reference problem"; If a client has multiple handles of the same object and deletes the object via one of them, all the others would be invalid, but not know it, so the client could write or read parts of the memory he shouldn't have access to. Is there a design pattern to prevent this from happening? Two ideas: An observer-like pattern where the destructor of an object would notify all handles. "Handle handles" (does such a thing even exist?). All the handles don't really point to the object, but to another handle. When the object gets destroyed, this "master-handle" invalidates itself and therefore all that point to it.

• Is there a good design pattern for this messaging class?

  - by salonMonsters

  Is there a good design pattern for this? I want to create a messaging class. The class will be passed: the type of message (eg. signup, signup confirmation, password reminder etc) the client's id The class needs to then look up the client's messaging preferences in the db (whether they want communication by email, sms or both) Then depending on the client's preference it will format the message for the medium (short version for sms, long form for email) and send it through our mail or sms provider's API. Because the fact that we want to be able to change out email and sms providers if need be I wondered if the Command Pattern would be a good choice.

• Is there a name for this functional programming construct/pattern?

  - by dietbuddha

  I wrote a function and I'd like to find out if it is an implementation of some functional programming pattern or construct. I'd like to find out the name of this pattern or construct (if it exists)? I have a function which takes a list of functions and does this to them: wrap(fn1, fn2, fn3, fn4) # returns partial(fn4, partial(fn3, partial(fn2, fn1))) There are strong similarities to compose, reduce, and other fp metaprogramming constructs, since the functions are being arranged together and returned as one function. It also has strong similarities to decorators and Python context managers since it provides a way to encapsulate pre and post execution behaviors in one function. Which was the impetus for writing this function. I wanted the ability that context managers provide, but I wanted to be able to have it defined in one function, and to be able to layer function after function on top.

• Does this factory method pattern example violate open-close?

  - by William

  In Head-First Design Patterns, they use a pizza shop example to demonstrate the factory method pattern. public abstract class PizzaStore { public Pizza orderPizza(String type) { Pizza pizza; pizza = createPizza(type); pizza.prepare(); pizza.bake(); pizza.cut(); pizza.box(); return pizza; } abstract Pizza createPizza(String type) } public class NYPizzaStore extends PizzaStore { Pizza createPizza(String item) { if (item.equals("cheese") { return new NYStyleCheesePizza(); } else if (item.equals("veggie")) { return new NYStyleVeggiePizza(); } else if (item.equals("clam")) { return new NYStyleClamPizza(); } else if (item.equals("pepperoni")) { return new NYStylePepperioniPizza(); } else return null; } } I don't understand how this pattern is not violating open-close. What if we require a beef Pizza, then we must edit the if statement in the NYPizzaStore class.

• Is there a 'design pattern' type listing of common algorithms?

  - by KevinM1

  Is there a 'design pattern' styled listing of common/popular algorithms anywhere? Specifically, something that has a similar format along the lines of: Algorithm Name: e.g., Quick Sort, Bubble Sort, etc. Problem: A description of the stereotypical problem the algorithm is supposed to address Description: Description of the solution Implementation: Code examples of the solution Big O Rating: Self-explanatory Similar Algorithms: Algorithms that address the same problem in different ways, or similar problems I really like the GoF design pattern listing style, and I think it would help me learn various algorithms better/easier if I could find a resource that was similar in terms of organization.

• How to Grab MAC Address of Active Ethernet Connection in Bash Script?

  - by Huy Tran

  Simple Question: How do I grab the MAC address of the active Ethernet connection in a bash script? I currently have: set - `/sbin/ifconfig eth0 | head -1` MAC=$5 Which outputs the MAC address of the eth0, but if it's eth1 that's active, I want that instead. Could I beforehand execute ifconfig | grep inet but that wouldn't tell me which interface is active, just that one is active. I need to grab the line above it to tell me which one is the active connection. Any help would be much appreciated. Thank you!

• How to simulate :active css pseudo class in android on non-link elements?

  - by chas s.

  I'd like to be able to mimic the behavior of the :active pseudo class on all elements in Android webkit. Currently, the :active syntax only works on a elements (links). Nearly all of the actionable elements in the app I'm working on are something other than a standard link tag. iOS webkit supports :active on all elements. /* works on both android iOS webkit */ a:active { color: blue; } /* works on iOS webkit, does not work on android webkit */ div:active { color: red; } I've found a couple of resources [1,2] that solve similar problems, but they're both a bit heavy, and I'm wondering if there's a lighter weight solution that I'm just not able to find. http://cubiq.org/remove-onclick-delay-on-webkit-for-iphone http://code.google.com/intl/ro-RO/mobile/articles/fast_buttons.html

• How to get httrack to work with SSL on mac os x? (libssl.so not found)

  - by cwd

  I'm trying to use httrack website copier but the program is running and reporting "no-ssl" (ie: it does not have the capability to copy secure sites). From looking over this thread, it seems that the problem is either when I make & configure the program, or when I run the program, it is not finding the lib-ssl / open-ssl that I have installed. I think it is looking for /var/root/lib/libssl.so.1.0 The user on that forum states that he created a symlink which allowed httrack to find the ssl library in the non-default location. Perhaps that's what I need to do - but where do I create the link from and to? I'm not seeing that I have any libssl.so files installed on my system. Do I need the development package? If so, how do I install that? I used macports to install the current version of openssl that I have. I'm running OS X 10.6. Reserch I have run this command to try and debug: dtruss httrack 2&1 | grep ssl and that outputs this: stat64("libssl.so.1.0\0", 0x7FFF5FBFEE30, 0x7FFF5FBFF470) = -1 Err#2

• get local groups and not the primary groups for a domain user

  - by user175084

  i have a code to get the groups a user belongs to. try { DirectoryEntry adRoot = new DirectoryEntry(string.Format("WinNT://{0}", Environment.UserDomainName)); DirectoryEntry user = adRoot.Children.Find(completeUserName, "User"); object obGroups = user.Invoke("Groups"); foreach (object ob in (IEnumerable)obGroups) { // Create object for each group. DirectoryEntry obGpEntry = new DirectoryEntry(ob); listOfMyWindowsGroups.Add(obGpEntry.Name); } return true; } catch (Exception ex) { new GUIUtility().LogMessageToFile("Error in getting User MachineGroups = " + ex); return false; } the above code works fine when i have to find the groups of a local user but for a domain user it returns a value "Domain User" which is kind of wierd as it is a part of 2 local groups. Please can some1 help in solving this mystery. thanks Research I did some finding and got that i am being returned the primary group of the domain user called "Domain User" group but what i actually want is the groups of the local machines the domain user is a part of... i cannot get that.. any suggestions another code using LDAP string domain = Environment.UserDomainName; DirectoryEntry DE = new DirectoryEntry("LDAP://" + domain, null, null, AuthenticationTypes.Secure); DirectorySearcher search = new DirectorySearcher(); search.SearchRoot = DE; search.Filter = "(SAMAccountName=" + completeUserName + ")"; //Searches active directory for the login name search.PropertiesToLoad.Add("displayName"); // Once found, get a list of Groups try { SearchResult result = search.FindOne(); // Grab the records and assign them to result if (result != null) { DirectoryEntry theUser = result.GetDirectoryEntry(); theUser.RefreshCache(new string[] { "tokenGroups" }); foreach (byte[] resultBytes in theUser.Properties["tokenGroups"]) { System.Security.Principal.SecurityIdentifier mySID = new System.Security.Principal.SecurityIdentifier(resultBytes, 0); DirectorySearcher sidSearcher = new DirectorySearcher(); sidSearcher.SearchRoot = DE; sidSearcher.Filter = "(objectSid=" + mySID.Value + ")"; sidSearcher.PropertiesToLoad.Add("distinguishedName"); SearchResult sidResult = sidSearcher.FindOne(); if (sidResult != null) { listOfMyWindowsGroups.Add((string)sidResult.Properties["distinguishedName"][0]); } } } else { new GUIUtility().LogMessageToFile("no user found"); } return true; } catch (Exception ex) { new GUIUtility().LogMessageToFile("Error obtaining group names: " + ex.Message + " Please contact your administrator."); // If an error occurs report it to the user. return false; } this works too but i get the same result "Domain Users" . Please can some1 tell me how to get the local machine groups...????

• Another design-related C++ question

  - by Kotti

  Hi! I am trying to find some optimal solutions in C++ coding patterns, and this is one of my game engine - related questions. Take a look at the game object declaration (I removed almost everything, that has no connection with the question). // Abstract representation of a game object class Object : public Entity, IRenderable, ISerializable { // Object parameters // Other not really important stuff public: // @note Rendering template will never change while // the object 'lives' Object(RenderTemplate& render_template, /* params */) : /*...*/ { } private: // Object rendering template RenderTemplate render_template; public: /** * Default object render method * Draws rendering template data at (X, Y) with (Width, Height) dimensions * * @note If no appropriate rendering method overload is specified * for any derived class, this method is called * * @param Backend & b * @return void * @see */ virtual void Render(Backend& backend) const { // Render sprite from object's // rendering template structure backend.RenderFromTemplate( render_template, x, y, width, height ); } }; Here is also the IRenderable interface declaration: // Objects that can be rendered interface IRenderable { /** * Abstract method to render current object * * @param Backend & b * @return void * @see */ virtual void Render(Backend& b) const = 0; } and a sample of a real object that is derived from Object (with severe simplifications :) // Ball object class Ball : public Object { // Ball params public: virtual void Render(Backend& b) const { b.RenderEllipse(/*params*/); } }; What I wanted to get is the ability to have some sort of standard function, that would draw sprite for an object (this is Object::Render) if there is no appropriate overload. So, one can have objects without Render(...) method, and if you try to render them, this default sprite-rendering stuff is invoked. And, one can have specialized objects, that define their own way of being rendered. I think, this way of doing things is quite good, but what I can't figure out - is there any way to split the objects' "normal" methods (like Resize(...) or Rotate(...)) implementation from their rendering implementation? Because if everything is done the way described earlier, a common .cpp file, that implements any type of object would generally mix the Resize(...), etc methods implementation and this virtual Render(...) method and this seems to be a mess. I actually want to have rendering procedures for the objects in one place and their "logic implementation" - in another. Is there a way this can be done (maybe alternative pattern or trick or hint) or this is where all this polymorphic and virtual stuff sucks in terms of code placement?

• Asp.net MVC and MOSS 2010 integration

  - by Robert Koritnik

  Just a sidenote: I'm not sure whether I should post this to serverfault as well, because some MOSS admin may have some info for me as well? A bit of explanation first (without Asp.net MVC) Is it possible to integrate the two? Is it possible to write an application that would share at least credential information with MOSS? I have to write a MOSS application that has to do with these technologies: MOSS 2010 Personal client certificates authentication (most probably on USB keys) Active Directory Federation Services Separate SQL DB that would serve application specific data (separate as not being part of MOSS DB) How should it work? Users should authenticate using personal certificates into MOSS 2010 There would be a certain part of MOSS that would be related to my custom application This application should only authorize certain users via AD FS - I guess these users should have a certain security claim attached to them This application should manage users (that have access to this app) with additional (app specific) security claims related to this application (as additional application level authorization rights for individual application parts) This application should use custom SQL 2008 DB heavily with its own data This application should have the possibility to integrate with external systems as well (Exchange for instance to inject calendar entries, ERP systems etc) This application should be able to export its data (from its DB) to files. I don't know if it's possible, but it would be nice if the app could add these files to MOSS and attach authorization info to them so only users with sufficient rights would be able to view/open these files. Why Asp.net MVC then? I'm very well versed in Asp.net MVC (also with the latest version) and I haven't done anything on Sharepoint since version 2003 (which doesn't do me no good or prepare me for the latest version in any way shape or form). This project will most probably be a death march project so I would rather write my application as a UI rich Asp.net MVC application and somehow integrate it into MOSS. But not only via a link, because I would like to at least share credentials, so users wouldn't need to re-login when accessing my app. Using Asp.net MVC I would at least have the possibility to finish on time or be less death marching. Is this at all possible? Questions Is it possible to integrate Asp.net MVC into MOSS as described above? If integration is not possible, would it be possible to create a completely MOSS based application that would work as described? Which parts of MOSS 2010 should I use to accomplish what I need?

• How to do role-based access control for a franchise business?

  - by FreshCode

  I'm building the 2nd iteration of a web-based CRM+CMS for a franchise service business in ASP.NET MVC 2. I need to control access to each franchise's services based on the roles a user is assigned for that franchise. 4 examples: Receptionist should be able to book service jobs in for her "Atlantic Seaboard" franchise, but not do any reporting. Technician should be able to alter service jobs, but not modify invoices. Managers should be able to apply discount to invoices for jobs within their stores. Owner should be able to pull reports for any franchises he owns. Where should franchise-level access control fit in between the Data - Services - Web layer? If it belongs in my Controllers, how should I best implement it? Partial Schema Roles class int ID { get; set; } // primary key for Role string Name { get; set; } Partial Franchises class short ID { get; set; } // primary key for Franchise string Slug { get; set; } // unique key for URL access, eg /{franchise}/{job} string Name { get; set; } UserRoles mapping short FranchiseID; // related to franchises table Guid UserID; // related to Users table int RoleID; // related to Roles table DateTime ValidFrom; DateTime ValidUntil; Background I built the previous CRM in classic ASP and it runs the business well, but it's time for an upgrade to speed up workflow and leave less room for error. For the sake of proper testing and better separation between data and presentation, I decided to implement the repository pattern as seen in Rob Conery's MVC Storefront series. Controller Implementation Access Control with [Authorize] attribute If there was just one franchise involved, I could simply limit access to a controller action like so: [Authorize(Roles="Receptionist, Technician, Manager, Owner")] public ActionResult CreateJob(Job job) { ... } And since franchises don't just pop up over night, perhaps this is a strong case to use the new Areas feature in ASP.NET MVC 2? Or would this lead to duplicate Views? Controllers, URL Routing & Areas Assuming Areas aren't used, what would be the best way to determine which franchise's data is being accessed? I thought of this: {franchise}/{controller}/{action}/{id} or is it better to determine a job's franchise in a Details(...) action and limit a user's action with [Authorize]: {job}/{id}/{action}/{subaction} {invoice}/{id}/{action}/{subaction} which makes more sense if any user could potentially have access to more than one franchise without cluttering the URL with a {franchise} parameter. Any input is appreciated.

• Socket server with multiple clients, sending messages to many clients without hurting liveliness

  - by Karl Johanson

  I have a small socket server, and I need to distribute various messages from client-to-client depending on different conditionals. However I think I have a small problem with livelyness in my current code, and is there anything wrong in my approach: public class CuClient extends Thread { Socket socket = null; ObjectOutputStream out; ObjectInputStream in; CuGroup group; public CuClient(Socket s, CuGroup g) { this.socket = s; this.group = g; out = new ObjectOutputStream(this.socket.getOutputStream()); out.flush(); in = new ObjectInputStream(this.socket.getInputStream()); } @Override public void run() { String cmd = ""; try { while (!cmd.equals("client shutdown")) { cmd = (String) in.readObject(); this.group.broadcastToGroup(this, cmd); } out.close(); in.close(); socket.close(); } catch (Exception e) { System.out.println(this.getName()); e.printStackTrace(); } } public void sendToClient(String msg) { try { this.out.writeObject(msg); this.out.flush(); } catch (IOException ex) { } } And my CuGroup: public class CuGroup { private Vector<CuClient> clients = new Vector<CuClient>(); public void addClient(CuClient c) { this.clients.add(c); } void broadcastToGroup(CuClient clientName, String cmd) { Iterator it = this.clients.iterator(); while (it.hasNext()) { CuClient cu = (CuClient)it.next(); cu.sendToClient(cmd); } } } And my main-class: public class SmallServer { public static final Vector<CuClient> clients = new Vector<CuClient>(10); public static boolean serverRunning = true; private ServerSocket serverSocket; private CuGroup group = new CuGroup(); public void body() { try { this.serverSocket = new ServerSocket(1337, 20); System.out.println("Waiting for clients\n"); do { Socket s = this.serverSocket.accept(); CuClient t = new CuClient(s,group); System.out.println("SERVER: " + s.getInetAddress() + " is connected!\n"); t.start(); } while (this.serverRunning); } catch (IOException ex) { ex.printStackTrace(); } } public static void main(String[] args) { System.out.println("Server"); SmallServer server = new SmallServer(); server.body(); } } Consider the example with many more groups, maybe a Collection of groups. If they all synchronize on a single Object, I don't think my server will be very fast. I there a pattern or something that can help my liveliness?
