  • Under what circumstances is jQuery's document.ready() not required?

    - by Phil.Wheeler
    While John Resig's recommendation is, quite rightly, to declare all events within a jquery.document.ready() function, I know that you don't actually have to put everything in there. In fact, there are cases where it may be more appropriate to deliberately put methods outside of the ready event. But what are those cases? Obviously best practice dictates that all events are declared within the ready event, so what would best practice be for declarations outside that event?

  • Placeholder for UITextView

    - by Gill Bates
    Anyone ever implements something in UITextView that stopping it from receiving future inputs when the text length is smaller than certain threshold? I plan to implement a textview like we have in the mail composer interface. We have a placeholder "Subject" there, and the cursor starts after. Placeholder in UITextView Inspired from this question, I wonder if there are some methods which could be used to stop changing the text in the UITextView once the cursor is moving back to the placeholder string. Any ideas?

  • Best way to return result from business layer to presentation layer when using LINQ-to-SQL

    - by samsur
    I have a business layer that has DTOs that are used in the presentation layer. This application uses entity framework. Here is an example of a class called RoleDTO: public class RoleDTO { public Guid RoleId { get; set; } public string RoleName { get; set; } public string RoleDescription { get; set; } public int? OrganizationId { get; set; } } In the BLL I want to have a method that returns a list of DTO. I would like to know which is the better approach: returning IQueryable or list of DTOs. Although I feel that returning IQueryable is not a good idea because the connection needs to be open. Here are the 2 different methods using the different approaches: First approach public class RoleBLL { private servicedeskEntities sde; public RoleBLL() { sde = new servicedeskEntities(); } public IQueryable<RoleDTO> GetAllRoles() { IQueryable<RoleDTO> role = from r in sde.Roles select new RoleDTO() { RoleId = r.RoleID, RoleName = r.RoleName, RoleDescription = r.RoleDescription, OrganizationId = r.OrganizationId }; return role; } Note: in the above method the DataContext is a private attribute and set in the constructor, so that the connection stays opened. Second approach public static List<RoleDTO> GetAllRoles() { List<RoleDTO> roleDTO = new List<RoleDTO>(); using (servicedeskEntities sde = new servicedeskEntities()) { var roles = from pri in sde.Roles select new { pri.RoleID, pri.RoleName, pri.RoleDescription }; //Add the role entites to the DTO list and return. This is necessary as anonymous types can be returned acrosss methods foreach (var item in roles) { RoleDTO roleItem = new RoleDTO(); roleItem.RoleId = item.RoleID; roleItem.RoleDescription = item.RoleDescription; roleItem.RoleName = item.RoleName; roleDTO.Add(roleItem); } return roleDTO; } } Please let me know, if there is a better approach.

  • Load a list of localized strings at once in IOS

    - by Victor Ronin
    I want to show a table with the list of strings which are localized. The straightforward method would be: a) Point data source to my ViewController b) Define an array c) Allocate the array in my ViewController and init (arrayWithObjects) it with the strings from localized resources (NSLocalizedString) d) Use this array in UITableViewDataSource delegated methods Mainly my concern is item b). The construction looks quite heavy and I wonder whether I can somehow specify and load whole list of localized string at once.

  • Java: JPQL search -similar- strings

    - by bguiz
    What methods are there to get JPQL to match similar strings? By similar I mean: Contains: search string is found within the string of the matches entity Case-insensitive Small mispellings: e.g. "arow" matches "arrow" I suspect the first two will be easy, however, I would appreciate help with the last one Thank you

  • ASP.NET MVC validation in weakly typed views

    - by Eedoh
    Hello. I have a problem validating data on view that is not strongly typed. I'm updating data from 3 different models on that view, and I have validation methods that work on them, but I don't know how to display the validation message. Where should I put validation messages (on strongly typed views I put them in ModelState, I presume that does not make sense in this case), and how should I display them (I doubt that I will be able to use "validationmessagefor", maybe "validationmessage" somehow)?

  • OpenMP implementations in VC++ 2008, 2010

    - by John
    Depending on implementation, OMP can be quite useful to parallelize fairly arbitrary bits of code - e.g a parallel section inside a method that calls two independent methods - or it can be bad. It depends on how threads are created/cached, I think. How does the VC++ 2008 implementation work? And is the 2010 implementation significantly different in terms of features and performance/flexibility?

  • How do you draw a string centered vertically in Java?

    - by Paul Alexander
    I know it's a simple concept but I'm struggling with the font metrics. Centering horizontally isn't too hard but vertically seems a bit difficult. I've tried using the FontMetrics getAscent, getLeading, getXXXX methods in various combinations but no matter what I've tried the text is always off by a few pixels. Is there a way to measure the exact height of the text so that it is exactly centered.

  • Are regexes really maintainable?

    - by Rich Bradshaw
    Any code I've seen that uses Regexes tends to use them as a black box: Put in string Magic Regex Get out string This doesn't seem a particularly good idea to use in production code, as even a small change can often result in a completely different regex. Apart from cases where the standard is permanent and unchanging, are regexes the way to do things, or is it better to try different methods?

  • Tab-Bar not hiding on all views

    - by Sheehan Alam
    I have a tab-bar controller that loads a RootView. The RootView has 4 buttons that will load a UITableView I don't want my tab-bar to be visible in the RootView so I added the following code: -(void)viewDidLoad{ self.hidesBottomBarWhenPushed = YES; } When I initially load the app the tab-bar doesn't appear, but when I click on a button, and go back to the RootView the tab-bar still appears. I have tried placing this code in viewWillAppear and other application lifecycle methods but no luck.

  • Abstract classes and Pod::Coverage

    - by Ken Williams
    I've recently started to try to use Dist::Zilla for maintaining Path::Class. I added the [PodCoverageTests] plugin, and it's reporting some failures in the Path::Class::Entity class, which is the abstract base class for Path::Class::File and Path::Class::Dir. What I'd like is some way to tell the testing code that Entity doesn't need docs, but its two derived classes do - even though the methods are only defined in the parent class. Anyone know some way to do that?

  • how can I get instance from the property.

    - by viky
    In my application I have a class which has properties of user-defined types like this: class MyType { public A MyProperty { get; set; } } class A { .....some methods and proeprties } for some operations that I need to perform from my main program, I create a List of MyProperty whenever creating object of MyType and pass it to my main program and there I perform different operation on these properties which reflects in there instances also. Is there any way by which I could get the object instance for any particular MyProperty from that property in the list.

  • Calling a webservice in javascript

    - by user303052
    So, I am trying to make a firefox extension which will use a webservice. I was looking online to find a way to do this. I was wondering if someone could explain what the following objects/methods do: service.useService(_, _); service.<`Service Name.callService(); If there is an alternative that does not include these objects, I would be happy to hear about it. Thank you very much

  • Why are static classes considered “classes” and “reference types”?

    - by Timwi
    I’ve been pondering about the C# and CIL type system today and I’ve started to wonder why static classes are considered classes. There are many ways in which they are not really classes: A “normal” class can contain non-static members, a static class can’t. In this respect, a class is more similar to a struct than it is to a static class, and yet structs have a separate name. You can have a reference to an instance of a “normal” class, but not a static class (despite it being considered a “reference type”). In this respect, a class is more similar to an interface than it is to a static class, and yet interfaces have a separate name. The name of a static class can never be used in any place where a type name would normally fit: you can’t declare a variable of this type, you can’t use it as a base type, and you can’t use it as a generic type parameter. In this respect, static classes are somewhat more like namespaces. A “normal” class can implement interfaces. Once again, that makes classes more similar to structs than to static classes. A “normal” class can inherit from another class. It is also bizarre that static classes are considered to derive from System.Object. Although this allows them to “inherit” the static methods Equals and ReferenceEquals, the purpose of that inheritance is questionable as you would call those methods on object anyway. C# even allows you to specify that useless inheritance explicitly on static classes, but not on interfaces or structs, where the implicit derivation from object and System.ValueType, respectively, actually has a purpose. Regarding the subset-of-features argument: Static classes have a subset of the features of classes, but they also have a subset of the features of structs. All of the things that make a class distinct from the other kinds of type, do not seem to apply to static classes. Regarding the typeof argument: Making a static class into a new and different kind of type does not preclude it from being used in typeof. Given the sheer oddity of static classes, and the scarcity of similarities between them and “normal” classes, shouldn’t they have been made into a separate kind of type instead of a special kind of class?

  • current transform being applied by canvas

    - by Allain Lalonde
    How can I determine the current transform that's being applied by an html5 canvas. It seems that it only supports two methods for dealing with transforms "transform", "setTransform" but I can't seem to discover the results of applying the transforms. Short of tracking them all myself and duplicating the the matrix mathematics that it must be doing natively, how can I figure out the current transform?

  • runModalForWindow throttles http requests

    - by Nikita Rybak
    I have url connection, which normally works fine NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:delegate]; But when I create a modal window, no request ever receives response: [NSApp runModalForWindow:window]; If I comment this line out, thus creating a 'standard' window, everything works. I tried implementing all methods from NSURLConnectionDelegate, not a single of them called. I suspect this is something about 'run loops', but have little experience in this area. Does anybody have experience in this? Thank you

    - by DarkSprout
    Using VBA and a toolbar button, I'd like to be able to Switch between FROM and Conversation View, but I just work how to or find any code to do this. I tried the Sort Methods but, they only work in memory and don't re-sort the actual inbox. I use Conversation View for GMail style functionality with my Sent items BCC'd to myself, but want to switch to 'From' with all Groups Collapsed - so that I can find emails from certain people quickly. Any Ideas? With Thanks =|)arkSprout=
