  • Jabber .net rostertree error

    - by Farooq
    Hi, Whenever I add the rostertree control to my form, I can see that the PresenceManager and RosterManager property values for it have this error listed: "Unable to cast object of type 'System.Windows.Forms.DataGridViewTextBoxColumn' to type 'System.ComponentModel.Component'." I can compile the solution and all but this error keeps popping up randomly. Can someone advice when this may happen. I'm thinking it has to do with the controls not being added properly. I'm using Visual Studio 2008. Thanks.

  • ASP.NET Model Binder and base type

    - by user137348
    My model inherits from an interface: public interface IGrid { ISearchExpression Search { get; set; } . . } public interface ISearchExpression { IRelationPredicateBucket Get(); } The model: public class Project : IGrid { public ISearchExpression Search { get; set; } public Project() { this.Search = new ProjectSearch(); } } The ProjectSearch: public class ProjectSearch: ISearchExpression { public string Name { get; set; } public string Number { get; set; } public IRelationPredicateBucket Get() {...} } And the strong typed partialview in the main view: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<ProjectSearch>" %> <%= Html.TextBoxFor(x=>x.Name)%> <%= Html.TextBoxFor(x => x.Number)%> .... When I submit the form, the Search property don't get bound properly. Everything is empty.The action takes an argument of ProjectSearch type. Why the Search don't get bound as supposed ?

  • Testing the context in asp.net mvc

    - by user252160
    I got pretty experienced with testing controllers, my question here is though, aren't we supposed to test the data context as well, and how ? I mean, there are a lot of relationships and constraints coming from the DB that simply testing controllers does not cover. On the other hand, testing against the DB is not considered a good practice - what then ? Simply testing without db.SubmitChanges() or what ?

  • asp.net MVC - how to get complete local and global resources

    - by Buthrakaur
    I'm localizing application and need to provide JSON representation of local and global resources for JS part of application for all views. My current idea is I'd implement HtmlHelper extension methods like GetLocalResourcesJSON/GetGlobalResourcesJSON which should encode all resource keys+values and return them JSON encoded as string (I'd implement caching as well). At the moment I'm able to retrieve single specific key from global or local resource belonging to current view (using httpContext.GetGlobalResourceObject/GetLocalResourceObject), but I'm not able to find out how to retrieve whole resource object and iterate all its keys+values. Is there any method how to achieve this? it looks like ResourceProviderFactory could be the the key to this problem, but it's not accessible publicly anywhere. I could instantiate ResourceExpressionBuilder and use reflection to retrieve the provider using GetLocal/GlobalResourceProvider() methods, but I don't like using reflection here at all...

  • asp.net MVC Partial Views how to initialise javascript

    - by Simon G
    Hi, I have an edit form that uses an ajax form to submit to the controller. Depending on the data submitted I redirect the user to one of two pages (by returning a partial view). Both pages rely on javascript/jquery and neither use anything common between the pages. What is the best way to initialise these javascripts on each page? I know there is the AjaxOption OnComplete but both pages are quite dynamic depending on the Model passed and I would rather keep the javascript for both pages seperate rather than having a common method. Thanks

  • Help with ASP.NET 4.0 routing and subfolders

    - by pixel3cs
    If I use routing with 2 query parameters, like this: System.Web.Routing.RouteTable.Routes.MapPageRoute("HomeRoute", "home/{f1}/{f2}", "~/Home.aspx"); My image does not appear on my Home.aspx page: <img src="~/img/img.jpg" /> or <img src="img/img.jpg" /> But it does appear when I access the http://localhost:3760/Website/Home.aspx URL I tried using Routing.Ignore with no luck. I look for a solution wich should work for an unlimited number of subfolders: "home/{f1}/{f2}/.../{fn}"

  • .NET - downloading multiple pages from a website with a single DNS query

    - by lampak
    I'm using HttpRequest to download several pages from a website (in a loop). Simplifying it looks like this: HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create( "http://sub.domain.com/something/" + someString ); HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); //do something I'm not quite sure actually but every request seems to resolve the address again (I don't know how to test if I'm right). I would like to boost it a little and resolve the address once and then reuse it for all requests. I can't work out how to force HttpRequest into using it, though. I have tried using Dns.GetHostAddresses, converting the result to a string and passing it as the address to HttpWebRequest.Create. Unfortunately, server returns error 404 then. I managed to google that's probably because the "Host" header of the http query doesn't match what the server expects. Is there a simple way to solve this?

  • .NET PostSubmitter sends backslashes

    - by Stefan N.
    Hi, I'm using C# to send JSON to a PHP-Script, like this: string json = "{"; json += "\"prop\":\"some text\""; json += "}"; PostSubmitter post = new PostSubmitter(); post.Url = "http://localhost/synch/notein.php"; post.Type = PostSubmitter.PostTypeEnum.Post; post.PostItems.Add("note", json); post.Post(); Of course I'll have to escape the inner quotes, but they get sended to the script! To make things worse: There is text, which already has quotation marks, so those must be escaped to be valid JSON. In this case I want the backslashes to be transmitted. Any idea to accomplish this?

  • Using implicit conversion as a substitute for multiple inheritance in .NET

    - by Daniel Plaisted
    I have a situation where I would like to have objects of a certain type be able to be used as two different types. If one of the "base" types was an interface this wouldn't be an issue, but in my case it is preferable that they both be concrete types. I am considering adding copies of the methods and properties of one of the base types to the derived type, and adding an implicit conversion from the derived type to that base type. Then users will be able treat the derived type as the base type by using the duplicated methods directly, by assigning it to a variable of the base type, or by passing it to a method that takes the base type. It seems like this solution will fit my needs well, but am I missing anything? Is there a situation where this won't work, or where it is likely to add confusion instead of simplicity when using the API?

  • Deserializing a type at the current stream position with protobuf-net

    - by Arne Claassen
    I'm serializing several objects into a single stream, but when i try to read them back, i can't seem to get anything but the last object: ProtoBuf.Serializer.Serialize(stream, postA1); ProtoBuf.Serializer.Serialize(stream, postB2); stream.Position = 0; var postA2 = ProtoBuf.Serializer.Deserialize<Post>(stream); var postB2 = ProtoBuf.Serializer.Deserialize<Post>(stream); The first deserialize moves the stream to the end and postA2 contains the value of postB2, while postB2 is just an uninitialized instance. Is this expected behavior, and if so, how do you deserialize an object from a random position in a stream?

  • DataTable vs. Collection in .Net

    - by B Pete
    I am writing a program that needs to read a set of records that describe the register map of a device I need to communicate with. Each record will have a handfull of fields that describe the properties of each register. I don't really need to edit or modify the data in my VB or C# program, though I would like to be able to display the data on a grid. I would like to store the data in a CSV file, or perhaps an XML file. I need to enable users to edit the data off-line, preferably in excel. I am considering using a DataTable or a Collection of "Register" objects (which I would define). I prototyped a DataTable, and found I can read/write XML easily using the built in methods and I can easily bind to a DataGridView. I was not able to find a way to retreive info on a single register without using a query that returns a collection of rows, even though I defined a unique primaty key column. The syntax to get a value from a column is also complex, though I could be missing something on both counts. I'm tempted to use a collection of "Register" objects that I can access via a unique key. It would be a little more coding up front, but seems like a cleaner solution overall. I should still be able to use LINQ to dataset to query subsets of registers when I need them, but would also be able to grab a single field using a the key value, something like this: Registers(keyValue).fieldName). Which would be a cleaner approach to the problem? Is there a way to read/write XML into a Collection without needing custom code? Could this be accomplished using String for a key?

  • Dependency Injection Question - ASP.NET

    - by Paul
    I'm starting a web application that contains the following projects: Booking.Web Booking.Services Booking.DataObjects Booking.Data I'm using the repository pattern in my data project only. All services will be the same, no matter what happens. However, if a customer wants to use Access, it will use a different data repository than if the customer wants to use SQL Server. I have StructureMap, and want to be able to do the following: Web project is unaffected. It's a web forms application that will only know about the services project and the dataobjects project. When a service is called, it will use StructureMap (by looking up the bootstrapper.cs file) to see which data repository to use. An example of a services class is the error logging class: public class ErrorLog : IErrorLog { ILogging logger; public ErrorLog() { } public ErrorLog(ILogging logger) { this.logger = logger; } public void AddToLog(string errorMessage) { try { AddToDatabaseLog(errorMessage); } catch (Exception ex) { AddToFileLog(ex.Message); } finally { AddToFileLog(errorMessage); } } private void AddToDatabaseLog(string errorMessage) { ErrorObject error = new ErrorObject { ErrorDateTime = DateTime.Now, ErrorMessage = errorMessage }; logger.Insert(error); } private void AddToFileLog(string errorMessage) { // TODO: Take this value from the web.config instead of hard coding it TextWriter writer = new StreamWriter(@"E:\Work\Booking\Booking\Booking.Web\Logs\ErrorLog.txt", true); writer.WriteLine(DateTime.Now.ToString() + " ---------- " + errorMessage); writer.Close(); } } I want to be able to call this service from my web project, without defining which repository to use for the data access. My boostrapper.cs file in the services project is defined as: public class Bootstrapper { public static void ConfigureStructureMap() { ObjectFactory.Initialize(x => { x.AddRegistry(new ServiceRegistry()); } ); } public class ServiceRegistry : Registry { protected override void configure() { ForRequestedType<IErrorLog>().TheDefaultIsConcreteType<Booking.Services.Logging.ErrorLog>(); ForRequestedType<ILogging>().TheDefaultIsConcreteType<SqlServerLoggingProvider>(); } } } What else do I need to get this to work? When I defined a test, the ILogger object was null. Thanks,

  • MS SQL and .NET Typed Dataset AllowDBNull Metadata

    - by Christian Pena
    Good afternoon, I am generating a typed dataset from a stored procedure. The stored procedure may contain something like: select t1.colA, t2.colA AS t2colA from t1 inner join t2 on t1.key = t2.key When I generate the typed dataset, the dataset knows whether t1.colA allows NULLs, but it always puts FALSE in AllowDBNull for t2.colA even if t2.colA allows NULL. Is this because the column is aliased? Is there any way, from SQL, to hint to VS that the column allows NULL? We currently have to go in and update the column's AllowDBNull if we regenerate the table. Thanks in advance. Christian

  • .NET Form_load priority

    - by mtranda
    So, the problem is such as this: I have a method that does stuff and updates a progress bar. If I call the method after the form is fully loaded (i.e.: by assigning it to a button on the form) everything works fine. The problem is that I need the method to start working as soon as the form loads, by itself, so I would place it in the Form_Load method. The problem is that even though I call Application.DoEvents() right before calling that method from within Form_Load, the form doesn't show up until the method has completed everything. As I said, if I let the form load first and call the method from another UI element for instance, everything works fine. Thanks in advance.

  • References between ASP.NET web applications.

    - by mcoolbeth
    I have a Visual Studio solution containing two web applications. I would like the first to depend on the second (pages in the first may contain links to, or possibly post to pages in the second). Furthermore, I would like to be able to launch the first project on a development server (standard debugging procedure for web apps in VS) and have the references to the second project be fully functional. Does anyone know the best way to achieve this? Thanks.
