  • ASP.NET Webforms site using HTTPCookie with 100 year timeout times out after 20 minutes

    - by Rob
    I have a site that is using Forms Auth. The client does not want the site session to expire at all for users. In the login page codebehind, the following code is used: // user passed validation FormsAuthentication.Initialize(); // grab the user's roles out of the database String strRole = AssignRoles(UserName.Text); // creates forms auth ticket with expiration date of 100 years from now and make it persistent FormsAuthenticationTicket fat = new FormsAuthenticationTicket(1, UserName.Text, DateTime.Now, DateTime.Now.AddYears(100), true, strRole, FormsAuthentication.FormsCookiePath); // create a cookie and throw the ticket in there, set expiration date to 100 years from now HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, FormsAuthentication.Encrypt(fat)) { Expires = DateTime.Now.AddYears(100) }; // add the cookie to the response queue Response.Cookies.Add(cookie); Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false)); The web.config file auth section looks like this: <authentication mode="Forms"> <forms name="APLOnlineCompliance" loginUrl="~/Login.aspx" defaultUrl="~/Course/CourseViewer.aspx" /> </authentication> When I log into the site I do see the cookie correctly being sent to the browser and passed back up: However, when I walk away for 20 minutes or so, come back and try to do anything on the site, the login window reappears. This solution was working for a while on our servers - now it's back. The problem doesn't occur on my local dev box running Cassini in VS2008. Any ideas on how to fix this?

  • Check malicious Redirect URL in ASP.NET

    - by acidzombie24
    I heard of sites using other site to redirect users either to their own site or to hide behind another site. In my code i redirect in a few places such as post a comment (its easier to use a return url then figure out the page using data given). How do i check if the return URL is my own url? I think i use absolute paths so i can easily check if the first character is '/' but then i will lose relative flexibility. This also disallows me from doing http://mysite.com/blah in the redirect url. I could patch the url by adding mysite + string but i'll need to figure out if string is a relative url or already a mysite.com url. Whats the easiest way to ensure i am only redirecting to my site?

  • Separate functionality depending on Role in ASP.NET MVC

    - by Andrew Bullock
    I'm looking for an elegant pattern to solve this problem: I have several user roles in my system, and for many of my controller actions, I need to deal with slightly different data. For example, take /Users/Edit/1 This allows a Moderator to edit a users email address, but Administrators to edit a user's email address and password. I'd like a design for separating the two different bits of action code for the GET and the POST. Solutions I've come up with so far are: Switch inside each method, however this doesn't really help when i want different model arguments on the POST :( Custom controller factory which chooses a UsersController_ForModerators and UsersController_ForAdmins instead of just UsersController from the controller name and current user role Custom action invoker which choose the Edit_ForModerators method in a similar way to above Have an IUsersController and register a different implementation of it in my IoC container as a named instance based on Role Build an implementation of the controller at runtime using Castle DynamicProxy and manipulate the methods to those from role-based implementations Im preferring the named IoC instance route atm as it means all my urls/routing will work seamlessly. Ideas? Suggestions?

  • .NET C# Explicit implementation of grandparent's interface method in the parent interface

    - by Cristi Diaconescu
    That title's a mouthful, isn't it?... Here's what I'm trying to do: public interface IBar { void Bar(); } public interface IFoo: IBar { void Foo(); } public class FooImpl: IFoo { void IFoo.Foo() { /*works as expected*/ } //void IFoo.Bar() { /*i'd like to do this, but it doesn't compile*/ } void IBar.Bar() { /*works as expected*/ } } So... Is there a way to declare IFoo.Bar(){...} in my class, other than basically merging the two interfaces into one? And, if not, why?

  • How do I 'donut cache' in ASP.NET MVC for something more than a date

    - by Simon_Weaver
    All the examples for donut caching I've seen are just like this : <%= Html.Substitute( c => DateTime.Now.ToString() )%> Thats fine if I just want the date, but what other options are there? I know there is a delegate 'MvcSubstitutionCallback' which has the following signature : public delegate string MvcSubstitutionCallback(HttpContextBase httpContext); but RenderAction and RenderPartial returns void so i cant just return them from the delegate method. How can I effectively use this callback for more complex situations. I've looked at both of Phil Haacked's articles here and here, but neither seems to do exactly what I want.

  • .NET: How to know when serialization is completed?

    - by Ian Boyd
    When I construct my control (which inherits DataGrid), I add specific rows and columns. This works great at design time. Unfortunately, at runtime I add my rows and columns in the same constructor, but then the DataGrid is serialized (after the constructor runs) adding more rows and columns. After serialization is complete, I need to clear everything and re-initialize the rows and columns. Is there a protected method that I can override to know when the control is done serializing? Of course, I'd prefer to not have to do the work in the constructor, throw it away, and do it again after (potential) serialization. Is there a preferred event that is the equivalent of "set yourself up now", so that it is called once whether I'm serialized or not? The serialization i speak of comes from the InitializeComponent() method in the form's code-behind file. #region Windows Form Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { ... } It would have been perfect if InitializeComponent was a virtual method defined by Control, then i could just override it and then perform my processing after i call base: protected override void InitializeComponent() { base.InitializeComponent(); InitializeMe(); } But it's not an ancestor method, it's declared only in the code-behind file. i notice that InitializeComponent calls SuspendLayout and ResumeLayout on various Controls. i thought it could override ResumeLayout, and perform my initialization then: public override void ResumeLayout() { base.ResumeLayout(); InitializeMe(); } But ResumeLayout is not virtual, so that's out. Anymore ideas? i can't be the first person to create a custom control.

  • .NET Assembly Diff / Compare Tool - What's available?

    - by STW
    I'd like to be able to do a code-level diff between two assemblies; the Diff plug-in for Reflector is the closest thing I've found so far, but to compare the entire assembly is a manual process requiring me to drill-down into every namespace/class/method. The other tools I've found so far appear to be limited to API-level (namespaces, classes, methods) differences--which won't cut it for what I'm looking for. Does anyone know of such a tool? My requirements (from highest to lowest) are: Be able to analyze / reflect the code content of two versions of the same assembly and report the differences Accept a folder or group of assemblies as input; quickly compare them (similar to WinMerge's folder diff's) Quick ability to determine if two assemblies are equivalent at the code level (not just the API's) Allow easy drill-down to view the differences Exporting of reports regarding the differences (Personally I like WinMerge for text diffs, so an application with a similar interface would be great)

  • ADO.NET parameters from TextBox

    - by Geo Ego
    I'm trying to call a parameterized stored procedure from SQL Server 2005 in my C# Winforms app. I add the parameters from TextBoxeslike so (there are 88 of them): cmd.Parameters.Add("@CustomerName", SqlDbType.VarChar, 100).Value = CustomerName.Text; I get the following exception: "System.InvalidCastException: Failed to convert parameter value from a TextBox to a String. ---> System.InvalidCastException: Object must implement IConvertible." The line throwing the error is when I call the query: cmd.ExecuteNonQuery(); I also tried using the .ToString() method on the TextBoxes, which seemed pointless anyway, and threw the same error. Am I passing the parameters incorrectly?

  • RenderPartial missing from Html Helper in ASP.NET MVC 2

    - by Guy
    I've just converted an application from MVC 1 to MVC 2 using the VS2010 wizard. Not found is the Html.RenderPartial which I have sprinkled around a number of views. I am guessing that this is something that I've done wrong because I see no mention of this as a breaking change in the white papers and docs. Everything I'm using is RTM/RTW and no beta or RC versions.

It needs to render the html like this: All Leads <i>(include Archive &amp; Trash)</i> How can I fix this? Thanks.

  • ASP.NET MVC grid/table

    - by nivlam
    public class Person { public string First { get; set; } public string Last { get; set; } public int Age { get; set; } public IEnumerable<Child> Children { get; set; } } public class Child { public string First { get; set; } public string Last { get; set; } public int Age { get; set; } } I'm searching for a way to render a table from my model, which is of type IEnumerable<Person>. I'm trying to generate the following table: <table> <tr class="person"> <td>First 1</td> <td>Last 1</td> <td>1</td> </tr> <tr class="child"> <td>First 1</td> <td>Last 1</td> <td>1</td> </tr> <tr class="child"> <td>First 2</td> <td>Last 2</td> <td>2</td> </tr> ... ... </table> Each person is a row and each of their children would be individual rows under the person row. This would repeat for each person in IEnumerable<Person>. Are there any grids or components that generate a table like this? I found MvcContrib's grid component, but it doesn't appear to be able to generate these child rows. Is there a way to extend MvcContrib's grid to do this?

  • ASP.NET - fast Segmented downoad of file through webservice

    - by H4mm3rHead
    Hi, Im doing this project where i need to download files through a webservice (images, videos). The download MUST go through an existing webservice. The existing webservice was made when there were no need to upload and download files but the project has changed and now we need to do It through a webservice. Right now I have implemented the download as a method that returns a byte[], I open a streamreader and resds the entire file into a byte[] and returns it to my method. This is working file on small files <~1Mb, above it takes too long time. I want to show some progress (e.g. when the user downlaods a 20Mb video) which i cannot do right now. And i want to make it download much faster (is a strategy to use multithreading and several threads that downloads a part of the file?). It is within a WPF application i need to do this. Any ideas on how to approach this?

  • Interesting interview question. .Net

    - by rahul
    Coding Problem NumTrans There is an integer K. You are allowed to add to K any of its divisors not equal to 1and K. The same operation can be applied to the resulting number and so on. Notice that starting from the number 4, we can reach any composite number by applying several such operations. For example, the number 24 can be reached starting from 4 using 5 operations: 468121824 You will solve a more general problem. Given integers n and m, return the minimal number of the described operations necessary to transform n into m. Return -1 if m can't be obtained from n. Definition Method signature: int GetLeastCount (int n, int m) Constraints N will be between 4 and 100000, inclusive. M will be between N and 100000, inclusive. Examples 1) 4 576 Returns: 14 The shortest order of operations is: 468121827365481108162243324432576 2) 8748 83462 Returns: 10 The shortest order of operations is: 874813122196832624439366590497873283106834488346083462 3) 4 99991 Returns: -1 The number 99991 can't be obtained because it’s prime!

  • ASP.Net MVC Outbound Route Matching Problem When Using ActionLink

    - by Godders
    Hi there, Hoping for some help after reading into MVC routing and not coming up with the answer myself. I have the following routes registered: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( null, "YourFeedback/Article/{resourceId}", new { controller = "YourFeedback", action = "Index", contentTypeId = new Guid(ConfigurationManager.AppSettings["ArticleLibraryId"]) }); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I have the following ActionLink in an aspx view: <%=Html.ActionLink("Your Feedback", "Article", "YourFeedback", new { resourceId = Model.ContentId.ResourceId }, new { @class = "yourFeedback" })%> My understanding of MVC routing is that this would render a anchor link with href of "/YourFeedback/Article/101" where 101 comes from Model.ContentId.ResourceId. Yet the anchor link href is rendered as "YourFeedback/Article/resourceId=101". Any ideas where I'm going wrong? Thanks in advance.
