• Using Windows Integrated Auth & Anonymous during redirect on IIS7

  - by James Black

  I have an application we bought that I need to integrate, and it uses jakarta connection to get to the application from IIS. So, the basic operation is: user goes to the url Gets redirected to the application SSO is enabled, so redirected back to IIS for fetching of domain credentials Back to application If username is blank show login page, else let user in. This is a simplification of all the steps, but the basic idea is here. My difficulty is that I need both Windows Integrated Auth and anonymous on, as some users won't have credentials, and need to be prompted for a username/password. I have looked at: http://stackoverflow.com/questions/2068546/iis-windows-authentication-before-anonymous already, but the user doesn't get to click on a link to decide. The application goes back to IIS looking for login.aspx and from there I want to either get their domain credentials or pass back to the application empty strings to signify that there are no credentials. It seems this isn't going to be possible though as if anonymous is on it doesn't make the 401 request so the credentials aren't passed. If I can't get this to work with just using an ASP page, could it be done using an ISAPI filter, or a module?

• VS2010 Intellisense on class files

  - by rlb.usa

  I have a Web Application Project that I'm working on. My solution looks like this : ./MyProject/ ./MyProject/dataobjects.cs <- no intellisense ./MyProject/sqlquerying.cs <- no intellisense ./MyProject/default.aspx <- intellisense works here ./MyProject/default.aspx.cs <- intellisense works here ./MyProject/mypage.aspx <- intellisense works here ./MyProject/mypage.aspx.cs <- intellisense works here Visual Studio 2010 doesn't give me any intellisense options when I work on non-code-behind files like Business Logic Layers and Data Logic Layers . In VS2008, I placed these files in the App_Code folder and intellisense worked fine. What can I do? Is there a specific folder I need to put these files in to get intellisense?

• Unable to read in my custom .config section

  - by Pure.Krome

  Hi folks, NOTE: this is very very similar to this SO question, but I need some more help. i'm trying to make the following section in my .config file, but i get an exception when trying to access this section. .config file <configSections> <section name="foos" type="Ackbar.Mvc.Models.Foo.FooCollection, Ackbar.Mvc" requirePermission="false"/> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler" requirePermission="false" /> </configSections> <foos> <add name="aaa" something="zzz"/> <add name="bbb" something="yyy"/> <add name="ccc" something="xxx"/> </foos> Ok, so this means i need to make two classes classes public class FooCollection : ConfigurationElementCollection { ... with my custom overrides, etc. ... } and public class FooElement : ConfigurationElement { [ConfigurationProperty("Name", IsRequired = true)] public string Name { .. } [ConfigurationProperty("Something ", IsRequired = true)] public string Something { .. } [ConfigurationProperty("IsDefault ", IsRequired = false, DefaultValue = false)] public bool IsDefault { .. } } Kewl. Now, when i do the following .... var whatever = ConfigurationManager.GetSection("foos") is throws the following exception :- An error occurred creating the configuration section handler for foos: Type 'Ackbar.Mvc.Models.Foos.FooCollection' does not inherit from 'System.Configuration.IConfigurationSectionHandler'. Can someone please help me? I don't want to wrap the collection INSIDE a parent section. Cheers :)

• How to design shape class

  - by Tomek Tarczynski

  I want to design shape class. I need to distinguish several different shapes: -Point -Line -Triangle -Circle -Polygons The main purpose of this class is to calculate distance between two shapes. I've all methods for calculating those distances, but I want to have a single method that can be used, it should looks like this: float Distance(Shape a, Shape b) Simplest way to do it is to put a lot of if statements and then invoke proper method but this is deffinitely not OOP. How to design such class in OOP style?

• How to create a numeric textbox in Silverlight?

  - by Mark Ingram

  As the title says really. I've had a look at inheriting from TextBox, but the only sensible override was "OnKeyDown", but that just gives me a key from the Key enum (with no way to use Char.IsNumeric()).

• How do I set the ItemsSource of a DataGrid in XAML?

  - by Ben McCormack

  I'm trying to set the ItemsSource property of a DataGrid named dgIssueSummary to be an ObservableCollection named IssueSummaryList. Currently, everything is working when I set the ItemsSource property in my code-behind: public partial class MainPage : UserControl { private ObservableCollection<IssueSummary> IssueSummaryList = new ObservableCollection<IssueSummary> public MainPage() { InitializeComponent(); dgIssueSummary.ItemsSource = IssueSummaryList } } However, I'd rather set the ItemsSource property in XAML, but I can't get it to work. Here's the XAML code I have: <sdk:DataGrid x:Name="dgIssueSummary" AutoGenerateColumns="False" ItemsSource="{Binding IssueSummaryList}" > <sdk:DataGrid.Columns> <sdk:DataGridTextColumn Binding="{Binding ProblemType}" Header="Problem Type"/> <sdk:DataGridTextColumn Binding="{Binding Count}" Header="Count"/> </sdk:DataGrid.Columns> </sdk:DataGrid> What do I need to do to set the ItemsSource property to be the IssueSummaryList in XAML rather than C#?

• BackgroundWorker.ReportProgress() not updating property and locking up the UI

  - by Willem

  i am using a backgroundWorker to do a long running operation: BackgroundWorker backgroundWorker = new BackgroundWorker() { WorkerSupportsCancellation = true, WorkerReportsProgress = true }; backgroundWorker.RunWorkerCompleted += delegate(object s, RunWorkerCompletedEventArgs args) { }; backgroundWorker.ProgressChanged += delegate(object s, ProgressChangedEventArgs args) { someViewModel.SomeProperty.Add((SomeObject)args.UserState); }; backgroundWorker.DoWork += delegate(object s, DoWorkEventArgs args) { someViewModel.SomeList.ForEach(x => { someViewModel.SomeInterface.SomeMethod(backgroundWorker, someViewModel, someViewModel.SomeList, x); }); }; backgroundWorker.RunWorkerAsync(); Then in SomeInterface.SomeMethod: public void SomeMethod(BackgroundWorker backgroundWorker, SomeViewModel someViewModel//....) { //Filtering happens backgroundWorker.ReportProgress(0, someObjectFoundWhileFiltering); } So, when it comes to: backgroundWorker.ProgressChanged += delegate(object s, ProgressChangedEventArgs args) { someViewModel.SomeProperty.Add((SomeObject)args.UserState);//Adding the found object to the Property in the VM }; On the line someViewModel.SomeProperty.Add((SomeObject)args.UserState);, the set on the Property is not firering and the UI just locks up. What am i doing wrong? Is this the correct way to update the UI thread?

• How do I tweet, using the DotNetOpenAuth library?

  - by MedicineMan

  I just downloaded the DotNetOpenAuth library and ran the AuthConsumer demo. It is an excellent library so far! Everything worked as advertised, which has not been my experience with a lot of Facebook and Twitter sample code that I have been working with recently. What I am trying to figure out is: How do I tweet using this library? I am currently planning to implement this in ASP MVC, but my initial thoughts is that the presentation platform doesn't matter all that much at the level I'm looking at.

• Resolution Problem with HttpRequestScoped in Autofac

  - by Page Brooks

  I'm trying to resolve the AccountController in my application, but it seems that I have a lifetime scoping issue. builder.Register(c => new MyDataContext(connectionString)).As<IDatabase>().HttpRequestScoped(); builder.Register(c => new UnitOfWork(c.Resolve<IDatabase>())).As<IUnitOfWork>().HttpRequestScoped(); builder.Register(c => new AccountService(c.Resolve<IDatabase>())).As<IAccountService>().InstancePerLifetimeScope(); builder.Register(c => new AccountController(c.Resolve<IAccountService>())).InstancePerDependency(); I need MyDataContext and UnitOfWork to be scoped at the HttpRequestLevel. When I try to resolve the AccountController, I get the following error: No scope matching the expression 'value(Autofac.Builder.RegistrationBuilder`3+<c__DisplayClass0[...]).lifetimeScopeTag.Equals(scope.Tag)' is visible from the scope in which the instance was requested. Do I have my dependency lifetimes set up incorrectly?

• How can I make the modal popup scroll its contents with the page?

  - by Middletone

  I've got a modal popup and when it loads contents that are taller than the browser height I am unable to scroll down to view the rest of the information. Instead the background can scroll but the popup won't. Instead I'd like to have the popup stay put and when the user scrolls up or down it leave the popup in place and let them scroll to the bottom of the contents. If you make a super long post on Facebook the popup works correctly and I'd like to know how I can get this same effect with this control.

• Does Windows Azure support the Application Warm-Up module or something similar?

  - by Corey O'Brien

  We have a Web Role that we are hosting in Windows Azure that uses an old ASMX based Web Reference to contact an external system. The Web Reference proxy code is big enough that instantiating it the first time has a significant cost. We'd like to be able to have this run when the Web Role starts instead of on the first request. I know IIS 7.5 has an Application Warm-Up module that would allow us to achieve this, but I'm having trouble figuring out if something similar exists with hosting on Windows Azure. Thanks, Corey

• How to use multiple instances of a usercontrol (with jquery) on the same page

  - by Julian

  Hi All, I've been working on an usercontrol with a jquery timer in it. At first I had the jquery within the usercontrol. But when I add 2 of those controls to my page the second usercontrol isn't showing it's data very well. Now I've put the jquery into the mainpage and the usercontrol only uses the id's of the jquery. Here is my usercontrol: <%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %> <style type="text/css"> #mainpanel { width: 145px; height: 123px; } </style> <div id="mainpanel"> <div> test</div> <div id="shortly" style="background-color: #FFFFFF"> </div> <button id="resetButton"> Reset </button> </div> Mainpage: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <%@ Register Src="WebUserControl.ascx" TagName="WebUserControl" TagPrefix="uc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>hoi</title> <script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="Scripts/jquery-ui-1.8.1.custom.min.js" type="text/javascript"></script> <link href="Css/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script> <script type="text/javascript" src="Scripts/jquery.countdown.js"></script> <script type="text/javascript"> $(document).ready(function () { $(function() { $("#mainpanel"); }); shortly = new Date(); shortly.setSeconds(shortly.getSeconds() + 5.5); $('#shortly').countdown({ until: shortly, onExpiry: liftOff, layout: '{sn}', }); $('#resetButton').click(function () { $('#mainpanel').effect("highlight", {}, 700 ); $('#shortly').effect("highlight", {}, 700 ); shortly = new Date(); shortly.setSeconds(shortly.getSeconds() + 5.5); $('#shortly').countdown('change', { until: shortly }); }); function liftOff() { // refresh the page window.location = window.location; } }); </script> </head> <body> <uc1:WebUserControl ID="WebUserControl1" runat="server" /> </body> </html> But still my usercontrols are acting weird, now my question is: "How can I make the SAME usercontrols work properly on ONE page?" Both of those use the same jquery code but the buttons etc. should only work within the usercontrol itself.

• How do you tell if your migrations are up to date with migratordotnet?

  - by Lance Fisher

  I'm using migratordotnet to manage my database migrations. I'm running them on application setup like this, but I would also like to check on application startup that the migrations are up to date, and provide the option to migrate to latest. How do I tell if there are available migrations that need to be applied? I see that I can get the migrations that were applied like this var asm = Assembly.GetAssembly(typeof(Migration_0001)); var migrator = new Migrator.Migrator("SqlServer", setupInfo.DatabaseConnectionString, asm); var applied = migrator.AppliedMigrations; I like to do something like this: var available = migrator.AvailableMigrations; //this property does not exist.
