  • Subsonic 3.0 - .Net - Error : Can not ceate an instance of an interface

    - by George
    Hi, I am new to Subsonic, I have configured Subsonic3.0 T4 Template and created classes for my project. I have taken GridView and Object Datasource. Object datasource will connect to the one of the classes which is created from subsonic. I have set object datasource for g\fetch, Insert, Update and delete methods. Then i set the datasource of grid witht he object datasource. Grid view successfully showing me all the records. But at the time of Update, Insert or delete it throws an exception that "Can not ceate an instance of an interface". And also i am not able to dwbug in the code of the subsonic. May be because of partial classes. Can anyone please let me know what is happening at the backgrund? Or may be one can give me sample example which contains subsonic 3.0 and grid add, edit and delete so it will be really helpful for me.... Please... :) Thanks, George

  • ASP.NET MVC: Route to URL

    - by JamesBrownIsDead
    What's the easiest way to get the URL (relative or absolute) to a Route in MVC? I saw this code here on SO but it seems a little verbose and doesn't enumerate the RouteTable. Example: List<string> urlList = new List<string>(); urlList.Add(GetUrl(new { controller = "Help", action = "Edit" })); urlList.Add(GetUrl(new { controller = "Help", action = "Create" })); urlList.Add(GetUrl(new { controller = "About", action = "Company" })); urlList.Add(GetUrl(new { controller = "About", action = "Management" })); With: protected string GetUrl(object routeValues) { RouteValueDictionary values = new RouteValueDictionary(routeValues); RequestContext context = new RequestContext(HttpContext, RouteData); string url = RouteTable.Routes.GetVirtualPath(context, values).VirtualPath; return new Uri(Request.Url, url).AbsoluteUri; } What's a better way to examine the RouteTable and get a URL for a given controller and action?

  • NHibernate session management in ASP.NET MVC

    - by Kevin Pang
    I am currently playing around with the HybridSessionBuilder class found on Jeffrey Palermo's blog post: http://jeffreypalermo.com/blog/use-this-nhibernate-wrapper-to-keep-your-repository-classes-simple/ Using this class, my repository looks like this: public class UserRepository : IUserRepository { private readonly ISessionBuilder _sessionBuilder; public UserRepository(ISessionBuilder sessionBuilder) { _sessionBuilder = sessionBuilder; } public User GetByID(string userID) { using (ISession session = _sessionBuilder.GetSession()) { return session.Get<User>(userID); } } } Is this the best way to go about managing the NHibernate session / factory? I've heard things about Unit of Work and creating a session per web request and flushing it at the end. From what I can tell, my current implementation isn't doing any of this. It is basically relying on the Repository to grab the session from the session factory and use it to run the queries. Are there any pitfalls to doing database access this way?

  • ADO.NET parameters from TextBox

    - by Geo Ego
    I'm trying to call a parameterized stored procedure from SQL Server 2005 in my C# Winforms app. I add the parameters from TextBoxeslike so (there are 88 of them): cmd.Parameters.Add("@CustomerName", SqlDbType.VarChar, 100).Value = CustomerName.Text; I get the following exception: "System.InvalidCastException: Failed to convert parameter value from a TextBox to a String. ---> System.InvalidCastException: Object must implement IConvertible." The line throwing the error is when I call the query: cmd.ExecuteNonQuery(); I also tried using the .ToString() method on the TextBoxes, which seemed pointless anyway, and threw the same error. Am I passing the parameters incorrectly?

  • Deserializing JSON in WCF throws xml errors in .Net 4.0

    - by Syg
    Hi there. I'm going slidely mad over here, maybe someone else can figure out what's going on here. I have a WCF service exposing a function using webinvoke, like so: [OperationContract] [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "registertokenpost" )] void RegisterDeviceTokenForYoumiePost(test token); The datacontract for the test class looks like this: [DataContract(Namespace="Zooma.Test", Name="test", IsReference=true)] public class test { string waarde; [DataMember(Name="waarde", Order=0)] public string Waarde { get { return waarde; } set { waarde = value; } } } When sending the following json message to the service, { "test": { "waarde": "bla" } } the trace log gives me errors (below). I have tried this with just a string instead of the datatype (void RegisterDeviceTokenForYoumiePost(string token); ) but i get the same error. All help is appreciated, can't figure it out. It looks like it's creating invalid xml from the json message, but i'm not doing any custom serialization here. The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'RegisterDeviceTokenForYoumiePost'. Unexpected end of file. **Following elements are not closed**: waarde, test, root.</Message><StackTrace> at System.ServiceModel.Dispatcher.OperationFormatter.DeserializeRequest(Message message, Object[] parameters)

  • ASP.NET MVC pass information from controller to view WITHOUT ViewData, ViewModel, or Session

    - by josh
    I have a unique scenario where I want a base controller to grab some data and store it in a list. The list should be accessible from my views just as ViewData is. I will be using this list on every page and would like a cleaner solution than just shoving it in the ViewDataDictionary. After attempting to come up with a solution, I thought I would create a custom ViewPage with a property to hold my list. My custom ViewPage would inherit from System.Web.MVC.ViewPage. However, I do not know where MVC passes the viewdata from the controller off to the view. More importantly, how do I get it to pass my list down to the view? Thanks for the help.

  • Matching .NET References to Namespaces

    - by maxp
    This seems confusing to me - im creating a class library, and adding all the necessary references for the source files contained in it. Now, off the bat, there were over 300 compiler errors complaining about missing namespaces. The library will now compile after i just added all of the System.* references, however this is obviously not the best way. I.e. if a classes needs using System.Web.Script;, there is no System.Web.Script reference, how would i find out which one of these references contained it? System.Web didnt.

  • .NET Remoting Connecting to Wrong Host

    - by Dark Falcon
    I have an application I wrote which has been running well for 4 years. Yesterday they moved all their servers around and installed about 60 pending Windows updates, and now it is broken. The application makes use of remoting to update some information on another server (10.0.5.230), but when I try to create my remote object, I get the following exception: Note that it is trying to connect to 127.0.0.1, not the proper server. The server (10.0.5.230) is listening on port 9091 as it should. This same error is happening on all three terminal servers where this application is installed. Here is the code which registers the remoted object: public static void RegisterClient() { string lServer; RegistryKey lKey = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Shoreline Teleworks\\ShoreWare Client"); if (lKey == null) throw new InvalidOperationException("Could not find Shoretel Call Manager"); object lVal = lKey.GetValue("Server"); if (lVal == null) throw new InvalidOperationException("Shoretel Call Manager did not specify a server name"); lServer = lVal.ToString(); IDictionary props = new Hashtable(); props["port"] = 0; string s = System.Guid.NewGuid().ToString(); props["name"] = s; ChannelServices.RegisterChannel(new TcpClientChannel(props, null), false); RemotingConfiguration.RegisterActivatedClientType(typeof(UpdateClient), "tcp://" + lServer + ":" + S_REMOTING_PORT + "/"); RemotingConfiguration.RegisterActivatedClientType(typeof(Playback), "tcp://" + lServer + ":" + S_REMOTING_PORT + "/"); } Here is the code which calls the remoted object: UpdateClient lUpdater = new UpdateClient(Settings.CurrentSettings.Extension.ToString()); lUpdater.SetAgentState(false); I have verified that the following URI is passed to RegisterActivatedClientType: "tcp://10.0.5.230:9091/" Why does this application try to connect to the wrong server?

  • Why .NET Boolean has TrueLiteral and TrueString?

    - by user309937
    Why in Boolean type there are two fields with the same value? internal const int True = 1; internal const int False = 0; internal const string TrueLiteral = "True"; internal const string FalseLiteral = "False"; and public static readonly string TrueString; public static readonly string FalseString; static Boolean() { TrueString = "True"; FalseString = "False"; } in reflector generated code, methods don't use those strings but: public string ToString(IFormatProvider provider) { if (!this) { return "False"; } return "True"; } would't it be better to use those const values?

  • [ASP.NET] IIS7 downloading file length

    - by GTD
    I've following code for file download: FileInfo fileInfo = new FileInfo(filePath); context.Response.Clear(); context.Response.ContentType = "application/octet-stream"; context.Response.AddHeader("Content-Disposition", "attachment; filename=" + System.IO.Path.GetFileName(filePath)); context.Response.AddHeader("Content-Length", fileInfo.Length.ToString()); context.Response.WriteFile(filePath); context.Response.End(); When I run it on my local IIS6 it works fine. Web browser (tested on IE8, Firefox 3.5.2, Opera 10) shows file length before I start download the file. When I run this code on remote IIS7, web browser doesn't shows file length. File length is unknown. Why I don't get file length when this code runs under IIS7?

  • RenderPartial missing from Html Helper in ASP.NET MVC 2

    - by Guy
    I've just converted an application from MVC 1 to MVC 2 using the VS2010 wizard. Not found is the Html.RenderPartial which I have sprinkled around a number of views. I am guessing that this is something that I've done wrong because I see no mention of this as a breaking change in the white papers and docs. Everything I'm using is RTM/RTW and no beta or RC versions.
