  • Prevent ASP.NET MVC Bundles Loading more than once

    - by Tim
    is there an inbuilt method of tracking if a bundle has already been loaded? I have several edit views which forexample require jquery and jquery.Validate etc libraries. Which i don't need to reference on the main layout page. Since a page could consist of several different conditional libraries ... ideally i would like @scripts.Render to know if i have already referenced a library and prevent its reloading. Cheers Tim

  • ASP MVC: Custom Validation Attribute

    - by user323395
    I'm trying to write my own Custom Validation attribute but i'm having some problems. The attribute i'm trying to write is that when a user logs in, the password will be compared against the confirmation password. namespace EventCompanion.Data.Attributes { public class ComparePassword : ValidationAttribute { public string PasswordToCompareWith { get; set; } public override bool IsValid(object value) { if (PasswordToCompareWith == (string)value) { return true; } return false; } } Now my problem is when i'm trying to set the attribute like this in the model file: [Required] [ComparePassword(PasswordToCompareWith=ConfirmPassword)] public string Password { get; set; } [Required] public string ConfirmPassword { get; set; } } I get the following error: Error 1 An object reference is required for the non-static field, method, or property 'Project.Data.Models.GebruikerRegistreerModel.ConfirmPassword.get' It seems that VS is not accepting the confirmpassword in the "PasswordToCompareWith=ConfirmPassword" part Now my question: What am i doing wrong? Thanks in advance!!!

  • String of KML needs to be converted to java objects

    - by spartikus
    I have a string of kml coming in on a request object. I have used xjc to create the kml java objects. I am looking for an easy way to create the kml nested java objects from this string. I could parse the string and create each object in the tree by hand but wouldn't it be cool if there was a library or something that would create the java objects for me? Something like KmlType type = parseKML(mykmlStringFromTheRequest); Then type would be a Tree of kml objects. Thanks for the help all.

    Hi All I just setup up member ship roles and registration on my website with visual web developer using the tutorial on msdn.

  • strerror_r returns trash when I manually set errno during testing

    - by Robert S. Barnes
    During testing I have a mock object which sets errno = ETIMEDOUT; The object I'm testing sees the error and calls strerror_r to get back an error string: if (ret) { if (ret == EAI_SYSTEM) { char err[128]; strerror_r(errno, err, 128); err_string.assign(err); } else { err_string.assign(gai_strerror(ret)); } return ret; } I don't understand why strerror_r is returning trash. I even tried calling strerror_r(ETIMEDOUT, err, 128) directly and still got trash. I must be missing something. It seems I'm getting the gnu version of the function not the posix one, but that shouldn't make any difference in this case.

  • NuGet Update Error?

    - by Myles McDonnell
    Using the NuGet package manager dialog at the solution level in the normal course of updating a package reference once the process is complete there is a green tick on the item and the update button disappears. However, with certain of my packages the update process completes, as far as I can tell successfully, but no green tick and the update button remains. Press it again and the next dialog shows that no projects require an update for that package. Am I missing something here or is this a bug?

  • Any simple Java way to pass parts of a hashmap to another hashmap?

    - by Arvanem
    Hi folks, For my trading program, a Merchant object has a qualities HashMap of enumerated Qualities with Boolean values. public class Merchants { private Map<Qualities, Boolean> qualities = new HashMap<Qualities, Boolean>(); I would like to give each Merchant object a further ratedQualities HashMap of True Qualities with Byte or Integer values representing the Rating of those Qualities. For example, a given Merchant could have a "1" Rating associated with their True Stockbroking Quality. The problem is Java does not let me do this easily. The following code demonstrates my intentions but doesn't compile: private Map<qualities-TRUE, Byte> ratedQualities = new HashMap<qualities-TRUE, Byte>(); According to this link text one solution is to create a Wrapper for the qualities HashMap. Is this the only solution or is there a better way? Thanks in advance for your help.

  • What's the .proto equivalent of List<T> in protobuf-net?

    - by Marc Bollinger
    To keep some consistency, we use code generation for a lot of our object models, and one of the offshoots of that has been generating the .proto files for ProtocolBuffers via a separate generation module. At this point though, I'm stumped at how to implement the generation for when it happens upon a List<T> object. It looks like this is possible via contracts: [ProtoMember(1)] public List<SomeType> MyList {get; set;} but outside of that, I'm not sure how or if it's possible to do this only from creating the .proto file/using the VS custom tool. Any thoughts?

  • PHP PDO: Fetching data as objects - properties assigned BEFORE __construct is called. Is this correc

    - by Erik
    The full question should be "Is this correct or is it some bug I can't count on?" I've been working with PDO more and in particular playing with fetching data directly into objects. While doing so I discovered this: If I fetch data directly into an object like this: $STH = $DBH->prepare('SELECT first_name, address from people WHERE 1'); $obj = $STH->fetchAll(PDO::FETCH_CLASS, 'person'); and have an object like this: class person { public $first_name; public $address; function __construct() { $this->first_name = $this->first_name . " is the name"; } } It shows me that the properties are being assigned before the __construct is being called -- because the names all have " is the name" appended. Is this some bug (in which case I can't/won't count on it) or is this The Way It Should Be. Because it's really quite a nice thing the way it works currently.

  • Invoking play on a QTMovie causes screensaver to deactivate on Snow Leopard

    - by ressaw
    I'm trying to port a working Leopard screensaver to Snow Leopard but it's deactivating after about half a second. The screensaver seems to deactivate upon invoking play on a QTMovie. And it deactivates both upon -play on the QTMovie object itself, and -play:self on the QTMovieView. If I don't actually call -play on the object, the screensaver does not deactivate and sits still on the first frame of the movie. Setting up the same code in a regular Cocoa Application works fine, and the screensaver also works fine in preview mode in the System Preferences. Any help is greatly appreciated.

  • How to drop a primary key using ActiveRecord migrations

    - by knoopx
    Due to a mistake I forgot to add :id => false to a has_many :trough table creation migration. Now I reverted the association back to a has_and_belongs_to_many and ActiveRecord throws an exception complaining about the presence of the primary key. I couldn't find any reference on the ActiveRecord documentation so, do you know if there is any standard, clean way of doing it?

  • How can I update a row and insert a new one automatically in NHibernate with one call to Save?

    - by snicker
    Let's say I have a Type II SCD database, that is basically append only. I am using NHibernate to persist objects to my database. I have an object like so: Pony |- int Id |- Guid EntityId |- string PonyName |- string PonyColor |- int RevisionValidFrom |- int RevisionValidTo Here's a typical scenario: Pony myLittlePony = myStable.GetLatestPonyByGuid("0f1ac08a-3328-43db-b278-77c272e4fea3"); myLittlePony.PonyColor = "Fish"; myNHSession.Save(myLittlePony); I want to be able to call Session.Save(myLittlePony) and have NHibernate UPDATE the old entity's RevisionValidTo to whatever I specify and then INSERT the modified Pony as a new row with a new Id, basically as if it were a brand new object being persisted to the DB.
