  • Silverlight 4 Default Button Service

    - by Mark Cooper
    For a few months I have been successfully using David Justices Default Button example in my SL 3 app. This approach is based on an attached property. After upgrading to SL4, the approach no longer works, and I get a XAML exception: "Unknown parser error: Scanner 2148474880" Has anyone succesfully used this (or any other) default button attached behaviours in SL4? Is there any other way to achieve default button behaviour in SL4 with the new classes that are available? Thanks, Mark

  • Understanding AddHandler and pass delegates and events.

    - by Achilles
    I am using AddHandler to wire a function to a control's event that I dynamically create: Public Sub BuildControl(EventHandler as System.Delegate) dim objMyButton as new button AddHandler objMyButton.Click, EventHandler end Sub This code is generating a run-time exception stating: Unable to cast object of type 'MyEventHandlerDelegate' to type 'System.EventHandler' What am I not understanding about System.Delegate even though AddHandler takes as an argument of type "System.Delegate"? What Type does "EventHandler need to be to cast to a type that AddHandler can accept? Thanks for your help!

  • Connection Refused running multiple environments on Selenium Grid 1.04 via Ubuntu 9.04

    - by ReadyWater
    Hello, I'm writing a selenium grid test suite which is going to be run on a series of different machines. I wrote most of it on my macbook but have recently transfered it over to my work machine, which is running ubuntu 9.04. That's actually my first experience with a linux machine, so I may be missing something very simple (I have disabled the firewall though). I haven't been able to get the multienvironment thing working at all, and I've been trying and manual reviewing for a while. Any recommendations and help would be greatly, greatly appreciated! The error I'm getting when I run the test is: [java] FAILED CONFIGURATION: @BeforeMethod startFirstEnvironment("localhost", 4444, "*safari", "http://remoteURL:8080/tutor") [java] java.lang.RuntimeException: Could not start Selenium session: ERROR: Connection refused I thought it might be the mac refusing the connection, but using wireshark I determined that no connection attempt was made on the mac .

  • Turn off iPhone/Safari input element rounding

    - by Alex
    My website renders well on the iPhone/Safari browser, with one exception: My text input fields have a weird rounded style which doesn't look good at all with the rest of my website. Is there a way to instruct Safari (via CSS or metadata) not to round the input fields and render them rectangular as intended?

  • Good event calendaring / scheduling design guide?

    - by Neil McF
    Hello, In an application I'm designing, the user has to be able to specify rather complex event scheduling (continuous time-block vs. daily time-blocks, exception date/times, recurrence patterns etc.) Does anyone know of a good design page for such a thing online? For example, I was highly impressed with this page's description of how to do database audit trails, and would love something similar. Thanks.

  • App.Config Best Practices ?

    - by abmv
    Normally when you have a application configuration file in your application and your application is expected to read from it. Is it good to check initially at start up if this file exists and raise an error and not to proceed at all ? (Worse case senarios) Or leave it to the unhandled exception manager to handle it and shut down the application? (WPF/Winforms etc)

  • How to bind DataTable to Chart series?

    - by user175908
    Hello, How to do bind data from DataTable to Chart series? I get null reference exception. I tried binding with square brackets and it did not worked either. So, how to do the binding? Thanks. P.S: I included DataGrid XAML and CS which works just fine. Converting data to List<KeyValuePair<string,int>> works good but it is kinda slow and is unnessesary trash in code. I use WPFToolkit (the latest version).

  • How do you handle EF Data Contexts combined with asp.net custom membership/role providers

    - by KallDrexx
    I can't seem to get my head around how to implement a custom membership provider with Entity Framework data contexts into my asp.net MVC application. I understand how to create a custom membership/role provider by itself (using this as a reference). Here's my current setup: As of now I have a repository factory interface that allows different repository factories to be created (right now I only have a factory for EF repositories and and in memory repositories). The repository factory looks like this: public class EFRepositoryFactory : IRepositoryFactory { private EntitiesContainer _entitiesContext; /// <summary> /// Constructor that generates the necessary object contexts /// </summary> public EFRepositoryFactory() { _entitiesContext = new EntitiesContainer(); } /// <summary> /// Generates a new entity framework repository for the specified entity type /// </summary> /// <typeparam name="T">Type of entity to generate a repository for </typeparam> /// <returns>Returns an EFRepository</returns> public IRepository<T> GenerateRepository<T>() where T : class { return new EFRepository<T>(_entitiesContext); } } Controllers are passed an EF repository factory via castle Windsor. The controller then creates all the service/business layer objects it requires and passes in the repository factory into it. This means that all service objects are using the same EF data contexts and I do not have to worry about objects being used in more than one data context (which of course is not allowed and causes an exception). As of right now I am trying to decide how to generate my user and authorization service layers, and have run against a design roadblock. The User/Authization service will be a central class that handles the logic for logging in, changing user details, managing roles and determining what users have access to what. The problem is, using the current methodology the asp.net mvc controllers will initialize it's own EF repository factory via Windsor and the asp.net membership/role provider will have to initialize it's own EF repository factory. This means that each part of the site will then have it's own data context. This seems to mean that if asp.net authenticates a user, that user's object will be in the membership provider's data context and thus if I try to retrieve that user object in the service layer (say to change the user's name) I will get a duplication exception. I thought of making the repository factory class a singleton, but I don't see a way for that to work with castle Windsor. How do other people handle asp.net custom providers in a MVC (or any n-tier) architecture without having object duplication issues?
