  • Custom roles in ASP.NET

    - by MainMa
    Hi, I am working on an ASP.NET website which uses forms authentication with a custom authentication mechanism (which sets e.Authenticated programmatically on protected void Login_Authenticate(object sender, AuthenticateEventArgs e)). I have an ASP.NET sitemap. Some elements must be displayed only to logged in users. Others must be displayed only to one, unique user (ie. administrator, identified by a user name which will never change). What I want to avoid: Set a custom role provider: too much code to write for a such basic thing, Transform the existing code, for example by removing sitemap and replacing it by a code-behind solution. What I want to do: A pure code-behind solution which will let me assign roles on authenticate event. Is it possible? How? If not, is there an easy-to-do workaround?

  • How to determine which class has called a function

    - by dannyc
    Hi, I am working on a Flex Front End at the moment, and have been using the Parsley framework for passing messages/events around. I was wondering if there is a simple way for a function (in this case, an event's constructor) to obtain a reference to the object which called it? This is to ensure that a certain event that I am defining can only be dispatched by one specified class. My thinking is to check the caller of the constructor somehow, and throw an error if it is not of the correct type. I am open to suggestions of alternative approaches here, but I would ideally like to stick to using the Parsley 'MessageHandler' approach if at all possible. Thanks for reading guys..

  • Erubis block helper throwing error with concat

    - by DEfusion
    I have a couple of block helpers, here's a simple example of what I'm doing: def wrap_foo foo, &block data = capture(&block) content = " <div class=\"foo\" id=\"#{foo}\"> #{data} </div>" concat( content ) end I'm just trying out erubis and it's giving me the following error: You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.<< Removing the call to concat removes the error but ends up with my wrapper not being rendered Using: Rails 2.3.5 Erubis 2.6.5 And tried this gem that helps Erubis (though 2.6.4) and Rails 2.3 play better together

    - by Sr.Richie
    I've just discovered a bug in my app, it looks like a Flash player bug, i would like to know if anyone has found a workaround or something.

Do you think there's any workaround for this? Is it really a flash bug?

  • ASP.NET - Manual authentication system

    - by Gal V
    Hello all, Wer'e developing an ASP.NET C# application, which will contain an authentication system that authenticates users in multiple levels (user, admin, super-admin, etc.). Our idea is NOT to use the built in ASP.NET forms authentication feature. Our plan is to create a whole 'new' system for it- based on the Session object, and SQL database contains users' info such as username & password. Is there any SERIOUS different between our idea to the Forms authentication feature? What security risks do we take? How do we solve them? Is this a good alternative for the forms authentication feature? Thanks in advance !

  • Is the first persistance of an Entity Data Model in EF 4.0 slower due to the connection cost ?

    - by Scott Davies
    Hi, I've got a console app written that persists an object graph via Entity Framework 4.0. I loop through this to dump the execution times for each persistance. The first persistance is always the largest. Is this due to EF making the initial connection to the database and/or JIT'ing ? Here's a sample of the output: Persisted graph in **3318** millseconds. Persisted graph in 25 millseconds. Persisted graph in 26 millseconds. Persisted graph in 22 millseconds. Thanks, Scott

  • How to override j_security_check in glassfish?

    - by Alex B
    I'm currently using FORM based authentication in glassfish v2.1 to log users in and it works fine. I want to switch to ProgrammaticLogin and I want to be able to get the initially requested URL (i.e. before redirecting to login page) and use it in my programmatic login code so that the user is redirected back to the requested page after authentication. I've seen the source code for j_security_check - in my case that's FormAuthenticator (catalina codebase) and it saves the initial request in a SavedRequest object in the session but that session is a StandardSession rather than HttpSession so there's no direct way to access it. Or should I change the authentication mechanism from FORM to something else? Thanks!

  • WPF/MVVM - should we create a different Class for each ViewModel ?

    - by FMFF
    I'm attempting the example from the excellent "How Do I" video for MVVM by Todd Miranda found in MSDN. I'm trying to adapt the example for my learning purpose. In the example, he has a ViewModel called EmployeeListViewModel. Now if I want to include Departments, should I create another ViewModel such as DepartmentListViewModel? The example has EmployeeRepository as the Data Source. In my case, I'm trying to use an Entity object as the datasource (Employees.edmx in Model folder and EmployeeRepository.cs in DataAccess folder). If I want to display the list of Departments, should I create a separate class called DepartmentRepository and put all department related method definitions there? What if I want to retrieve the employee name and their department's name together? Where should I place the methods for this? I'm very new to WPF and MVVM and please let me know if any of the above needs to be re-phrased. Thank you for all the help.

  • Javascript clears a variable after there is no further reference it

    - by Praveen Prasad
    It is said, javascript clears a variable from memory after its being referenced last. just for the sake of this question i created a JS file with only one variable; //file start //variable defined var a=["Hello"] //refenence to that variable alert(a[0]); // //file end no further reference to that variable, so i expect javascript to clear varaible 'a' Now i just ran this page and then opened firebug and ran this code alert(a[0]); Now this alerts the value of variable, If the statement "Javascript clears a variable after there is no further reference it" is true how come alert() shows its value. Is it because all variable defined in global context become properties of window object, and since even after the execution file window objects exist so does it properties.

  • Use the [Serializable] attribute or subclassing from MarshalByRefObject?

    - by Theo Lenndorff
    I'd like to use an object across AppDomains. For this I can use the [Serializeable] attribute: [Serializable] class MyClass { public string GetSomeString() { return "someString" } } Or subclass from MarshalByRefObject: class MyClass: MarshalByRefObject { public string GetSomeString() { return "someString" } } In both cases I can use the class like this: AppDomain appDomain = AppDomain.CreateDomain("AppDomain"); MyClass myObject = (MyClass)appDomain.CreateInstanceAndUnwrap( typeof(MyClass).Assembly.FullName, typeof(MyClass).FullName); Console.WriteLine(myObject.GetSomeString()); Why do both approaches seem to have the same effect? What is the difference in both approaches? When should I favor the one approach over the other? EDIT: At the surface I know that there are differences between both mechanisms, but if someone jumped out of a bush and asked me the question I couldn't give him a proper answer. The questions are quite open questions. I hoped that someone can explain it better than I could do.

  • Using Interfaces in an action signature of ASP.NET MVC controller

    - by Dmitry Borovsky
    Hello, I want to use interface in Action signature. So I've tried make own ModelBinder by deriving DefaultModelBinder: public class InterfaceBinder<T> : DefaultModelBinder where T: new() { protected override object CreateModel(ControllerContext controllerContext, ModelBindingContext bindingContext, Type modelType) { return base.CreateModel(controllerContext, bindingContext, typeof(T)); } } public interface IFoo { string Data { get; set; } } public class Foo: IFoo /*other interfaces*/ { /* a lot of other methods and properties*/ public Bar Data{get;set;} string IFoo.Data { get{return Data.ToString()}; set{Data = new Bar(value)}; } } public class MegaController: Controller { public ActionResult Process([ModelBinder(typeof(InterfaceBinder<Foo>))]IFoo foo){/*bla-bla-bla*/} } But it doesn't work. Does anybody have idea how release this behaviour? And yes, I know that I can make my own implementation of IModelBinder, but I'm looking for easier way.

  • Rails - How do i update a records value in a join model ?

    - by ChrisWesAllen
    I have a join model in a HABTM relationship with a through association (details below). I 'm trying to find a record....find the value of that records attribute...change the value and update the record but am having a hard time doing it. The model setup is this User.rb has_many :choices has_many :interests, :through => :choices Interest.rb has_many :choices has_many :users, :through => :choices Choice.rb belongs_to :user belongs_to :interest and Choice has the user_id, interest_id, score as fields. And I find the ?object? like so @choice = Choice.where(:user_id => @user.id, :interest_id => interest.id) So the model Choice has an attribute called :score. How do I find the value of the score column....and +1/-1 it and then resave? I tried @choice.score = @choice.score + 1 @choice.update_attributes(params[:choice]) flash[:notice] = "Successfully updated choices value." but I get "undefined method score"......What did i miss?

  • Is there a standard .NET exception to throw when a class doesn't implement a required attribute?

    - by a typing monkey
    Suppose I want to throw a new exception when invoking a generic method with a type that doesn't have a required attribute. Is there a .NET exception that's appropriate for this situation, or, more likely, one that would be a suitable ancestor for a custom exception? For example: public static class ClassA { public static T DoSomething<T>(string p) { Type returnType = typeof(T); object[] typeAttributes = returnType.GetCustomAttributes(typeof(SerializableAttribute), true); if ((typeAttributes == null) || (typeAttributes.Length == 0)) { // Is there an exception type in the framework that I should use/inherit from here? throw new Exception("This class doesn't support blah blah blah"); // Maybe ArgumentException? That doesn't seem to fit right. } } } Thanks.

  • EXT JS toLayout on Viewport doesnt show anything...

    - by Nazariy
    After reading many example about adding new components in to existing container without reloading whole page I run in to small problem while combining tree and tabs inside Viewport component. What I'm trying to do is to register on click event to tree node and load in to content container new component, depending on node type it can be tabpanel, gridpanel or any other available component. here is short example of tree object: { xtype: 'treepanel', id: 'tree-panel', listeners: { click: function(n) { var content = Ext.getCmp('content-panel'); content.setTitle(n.attributes.qtip); //remove all components from content-panel content.removeAll(); content.add(dummy_tabs2); content.doLayout(); return; } }} All DOM manipulation went fine, everything registered properly, new Title shown, but dummy_tabs2 are not shown. I did try to set various properties for doLayout(true|false, true|false) but nothing happens. Am I doing something wrong?

  • adhoc struct/class in C#?

    - by acidzombie24
    Currently i am using reflection with sql. I find if i want to make a specialize query it is easiest to get the results by creating a new class inheriting from another and adding the 2 members/columns for my specialized query. Then due to reflections in the lib in my c# code i can write foreach(var v in list) { v.AnyMember and v.MyExtraMember) Now instead of having the class scattered around or modifying my main DB.cs file can i define a class inside a function? I know i can create an anonymous object by writing new {name=val, name2=...}; but i need a to pass this class in a generic function func(query, args);

  • declaring a 2D array of pointer objects

    - by Tyler Stennette
    I'm having a tough time figuring out how to instantiate a 2D array of pointer objects. Here is how I'm doing it: Pieces* chessBoard[9][9]; When I want to set it to an actual object pointer, I'm doing the following: chessBoard[1][1] = new Rook(p1Rook); Rook is a class that inherits attributes from the Pieces class and p1Rook is a char variable set to 'R'. This class also implements virtual functions (not pure virtual) from Pieces such as move() or getPiece() that are unique to the particular chess piece. However, when I compile my program, I get the following error: ChessBoard.cpp:69: error: expected type-specifier before ‘Rook’ ChessBoard.cpp:69: error: cannot convert ‘int*’ to ‘Pieces*’ in assignment Can someone please explain what I should change to get rid of this rather annoying persistent error? I would appreciate it.

Then the line e.Cancel = true is executed and the form is not closed. Now the thing is, after this if i close the application from task manager the close reason is UserClosing !!! Why? Shouldn't it be TaskManagerClosing?

  • How to select a dynamic datepicker instance in order to extend it with jQuery

    - by JaredC
    I'm trying to control positioning of a jQuery datepicker element. I like the solution offered at http://stackoverflow.com/questions/1818670/how-to-control-positioning-of-jqueryui-datepicker for overriding the _checkOffset fn: $.extend(window.DP_jQuery.datepicker,{_checkOffset:function(inst,offset,isFixed){return offset}}); However, this results in a 'window.DP_jQuery is undefined' error. Upon inspection, I can see that the DP_jQuery object in the DOM gets named with a random string, like so: DP_jQuery_123456. If I use this full name in the above code, it works wonderfully. My question is whether there's a way to exend the _checkOffset fn for a datepicker instance without knowing before-hand what the instance name is? For example, can I use some sort of wildcard to select all datepicker instances that begin with 'DP_jQuery_'? Thanks

  • ASP.NET MVC: Route to URL

    - by JamesBrownIsDead
    What's the easiest way to get the URL (relative or absolute) to a Route in MVC? I saw this code here on SO but it seems a little verbose and doesn't enumerate the RouteTable. Example: List<string> urlList = new List<string>(); urlList.Add(GetUrl(new { controller = "Help", action = "Edit" })); urlList.Add(GetUrl(new { controller = "Help", action = "Create" })); urlList.Add(GetUrl(new { controller = "About", action = "Company" })); urlList.Add(GetUrl(new { controller = "About", action = "Management" })); With: protected string GetUrl(object routeValues) { RouteValueDictionary values = new RouteValueDictionary(routeValues); RequestContext context = new RequestContext(HttpContext, RouteData); string url = RouteTable.Routes.GetVirtualPath(context, values).VirtualPath; return new Uri(Request.Url, url).AbsoluteUri; } What's a better way to examine the RouteTable and get a URL for a given controller and action?

  • Does Hibernate's GenericGenerator cause update and saveOrUpdate to always insert instead of update?

    When using GenericGenerator to generate unique identifiers, do Hibernate session methods update() and saveOrUpdate() always insert instead of update table rows, even when the given object has an existing identifier (where the identifier is also the table primary key)? Is this the correct behaviour? public class User { private String id; private String name; public User(String id, String name) { this.id = id; this.name = name; } @GenericGenerator(name="generator", strategy="guid")@Id @GeneratedValue(generator="generator") @Column(name="USER_ID", unique=true, nullable=false) public String getId() { return this.id; } public void setId(String id) { this.id = id; } @Column(name="USER_NAME", nullable=false, length=20) public String getUserName() { return this.userName; } public void setUserName(String userName) { this.userName = userName; } } class UserDao extends AbstractDaoHibernate { public void updateUser(final User user) { HibernateTemplate ht = getHibernateTemplate(); ht.saveOrUpdate(user); } }
