  • Variable scope and the 'using' statement in .NET

    - by pete the pagan-gerbil
    If a variable is at class level (ie, private MyDataAccessClass _dataAccess;, can it be used as part of a using statement within the methods of that class to dispose of it correctly? Is it wise to use this method, or is it better to always declare a new variable with a using statement (ie, using (MyDataAccessClass dataAccess = new MyDataAccessClass()) instead of using (_dataAccess = new MyDataAccessClass()))?

  • is there an easy way to convert jquery code to javascript?

    - by davidsleeps
    hopefully the question doesn't sound stupid, but there are lots of examples out there of achieving certain things in javascript/dom using jQuery. Using jQuery is not always an option (or even a want) which can make understanding the examples of javascript solutions written in jQuery hard. Is there an easy way to convert jQuery code to regular javascript? I guess without having to access or understand the jQuery source code... edit (future readers): pretend there is a logical reason why jQuery isn't available!

  • Overriding initial value in ModelForm

    - by schneck
    Hi, in my Django (1.2) project, I want to prepopulate a field in a modelform, but my new value is ignored. This is the snippet: class ArtefactForm(ModelForm): material = CharField(widget=AutoCompleteWidget('material', force_selection=False)) def __init__(self, *args, **kwargs): super(ArtefactForm, self).__init__(*args, **kwargs) self.fields['material'].initial = 'Test' I also tried with self.base_fields, but no effect: there is always the database-value displaying in the form. Any ideas?

  • How to set Win32 window as owner of WPF window?

    - by Sam
    I want to use WPF windows in a legacy win32 application. I'd like to behave them in a similar way, like the WPF window always being displayed on top of the win32 window. For this I'd like to set the owner of the WPF window to the win32 windows, but I got no idea how to achieve this. Any help here?

  • Detecting jQuery UI autocomplete

    - by Soldarnal
    How can I detect whether or not an input box is currently a jQuery UI autocomplete? There doesn't seem to be a native method for this, but I'm hoping there is something simple like this: if ($("#q").autocomplete) { //Do something } That conditional, however, seems to always return true.

  • What language is .NET Framework written in?

    - by chester89
    The question I always wanted to ask and was afraid to, actually - what language is .NET Framework written in? I mean library itself. It seems to me that it was C and C++ mostly. (I hope Jon Skeet is reading this one, it`ll be very interesting to hear what he thinks about it)

  • How deep are your unit tests?

    - by John Nolan
    The thing I've found about TDD is that its takes time to get your tests set up and being naturally lazy I always want to write as little code as possible. The first thing I seem do is test my constructor has set all the properties but is this overkill? My question is to what level of granularity do you write you unit tests at? ..and is there a case of testing too much?

  • Using Entity Framework 4.0 with Code-First and POCO: How to Get Parent Object with All its Children

    - by SirEel
    I'm new to EF 4.0, so maybe this is an easy question. I've got VS2010 RC and the latest EF CTP. I'm trying to implement the "Foreign Keys" code-first example on the EF Team's Design Blog, http://blogs.msdn.com/efdesign/archive/2009/10/12/code-only-further-enhancements.aspx. public class Customer { public int Id { get; set; public string CustomerDescription { get; set; public IList<PurchaseOrder> PurchaseOrders { get; set; } } public class PurchaseOrder { public int Id { get; set; } public int CustomerId { get; set; } public Customer Customer { get; set; } public DateTime DateReceived { get; set; } } public class MyContext : ObjectContext { public RepositoryContext(EntityConnection connection) : base(connection){} public IObjectSet<Customer> Customers { get {return base.CreateObjectSet<Customer>();} } } I use a ContextBuilder to configure MyContext: { var builder = new ContextBuilder<MyContext>(); var customerConfig = _builder.Entity<Customer>(); customerConfig.Property(c => c.Id).IsIdentity(); var poConfig = _builder.Entity<PurchaseOrder>(); poConfig.Property(po => po.Id).IsIdentity(); poConfig.Relationship(po => po.Customer) .FromProperty(c => c.PurchaseOrders) .HasConstraint((po, c) => po.CustomerId == c.Id); ... } This works correctly when I'm adding new Customers, but not when I try to retrieve existing Customers. This code successfully saves a new Customer and all its child PurchaseOrders: using (var context = builder.Create(connection)) { context.Customers.AddObject(customer); context.SaveChanges(); } But this code only retrieves Customer objects; their PurchaseOrders lists are always empty. using (var context = _builder.Create(_conn)) { var customers = context.Customers.ToList(); } What else do I need to do to the ContextBuilder to make MyContext always retrieve all the PurchaseOrders with each Customer?

  • Crackers - How do they do it, how do we fight back?

    - by zedo
    As someone who is interested in learning more about the security side of technology, I ask you all the following questions: How is it that crackers crack software? What techniques are used to do so? I would imagine that the cracking methods depend upon the language the software is written in, right? Aside from using something like cloud-based security for SaaS ((software as a service) which isn't always an option), what choices does one have to prevent their software from being compromised?

  • In 2011 is it truly necessary to still degrade js?

    - by 0plus1
    Serious question. I tried most of the famous websites (including facebook) and I can say that tons of functionality doesn't degrade at all with js disabled. I've been always told that js should degrade gracefully, but does this still applies in these day and age? ie6 support is being dropped by several sites, and most of the web2.0 relies heavily on js (especially ajax, I even found some sites that doesn't let you login without js enabled). What are your thought about it?

  • Cannot open a .tif with color using .Net Image or Bitmap classes

    - by Tom Regan
    I am attempting to open .tif files that have color in them (300 dpi, PixelFormat.Format24bppRgb) using the .Net Image and Bitmap classes. I always get an "invalid parameter" error when the tiffs have color (works fine for black and white tiffs). If anyone has source code on how to open a .tif with color in it I'd deeply appreciate it. Below is what I'm attempting to do; this also fails when calling Bitmap.FromStream: using (FileStream fs = File.OpenRead(fileName)) { using (Image img = Image.FromStream(fs)) {} }
