  • Passing through lists from jQuery to the service

    - by thedixon
    I'm sure I've done this in another solution, but I can't seem to find any solution as to do it again and wondered if anyone can help me... This is my WebAPI code: public class WebController : ApiController { public void Get(string telephone, string postcode, List<Client> clients) { } } And, calling this from jQuery: function Client(name, age) { this.Name = name; this.Age = age; } var Clients = []; Clients.push(new Client("Chris", 27)); $.ajax({ url: "/api/Web/", data: { telephone: "999", postcode: "xxx xxx", clients: Clients } }); But the "clients" object always comes back as null. I've also tried JSON.stringify(Clients), and this is the same result. Can anyone see anything obvious I'm missing here?

  • Undocumented feature of Dictionary?

    - by Jon
    Dictionary<string, int> testdic = new Dictionary<string, int>(); testdic.Add("cat", 1); testdic.Add("dog", 2); testdic.Add("rat", 3); testdic.Remove("cat"); testdic.Add("bob", 4); Fill the dictionary and then remove the first element. Then add a new element. Bob then appears at position 1 instead of at the end, therefore it seems to remember removed entries and re-uses that memory space? Is this documented anywhere because I can't see it on MSDN and has caused me a day of grief because I assumed it would just keep adding to the end.

  • How can I get the assembly last modified date?

    - by Juan Manuel Formoso
    I want to render (for internal debugging/info) the last modified date of an assembly, so I know when was a certain website deployed. Is it possible to get it though reflection? I get the version like this, I'm looking for something similar: Assembly.GetExecutingAssembly().GetName().Version.ToString(); ie: I don't want to open the physical file, get its properties, or something like that, as I'll be rendering it in the master page, and don't want that kind of overhead.

  • Customer provider Password Reset client.

    - by ProfK
    I'm looking for guidence on writing a custom password reset UI, but it must fit the Provider 'Pattern', or degrade silently to built-in defaults. E.g. my Reset Control must collect extra information, and perform differently to the standard Password Recovery Control. It must close as possible use the standard MembershipProvider interface for standard functions, and only use an extended interface for the non-standard stuff. I'd like some reading on issues such as, what must I ask the Membership Provider for, and what must I do myself. What must I tell the provider (service?) about what I do? Etc.

  • Declaring an object of a conditional type with a System.Type

    - by Chapso
    I am attempting to launch a specific form depending on the selected node of a treeview on the doubleclick event. The code I need to use to launch the form is a little bulky becuase I have to ensure that the form is not disposed, and that the form is not already open, before launching a new instance. I'd like to have all of this checking happen in one place at the end of the function, which means that I have to be able to pass the right form type to the code at the end. I'm trying to do this with a System.Type, but that doesn't seem to be working. Could someone point me in the right direction, please? With TreeView.SelectedNode Dim formType As Type Select Case .Text Case "Email to VPs" formType = EmailForm.GetType() Case "Revise Replacers" formType = DedicatedReplacerForm.GetType() Case "Start Email" formType = EmailForm.GetType() End Select Dim form As formType Dim form As formType Try form = CType(.Tag, formType) If Not form.IsDisposed Then form.Activate() Exit Sub End If Catch ex As NullReferenceException 'This will error out the first time it is run as the form has not yet ' been defined. End Try form = New formType form.MdiParent = Me .Tag = form CType(TreeView.SelectedNode.Tag, Form).Show() End With

  • MVC4 not binding a list of basic types

    - by admanb
    I cannot, for the life of me, get this data to bind. Here's my JavaScript: var params = { 'InvItemIDs': ["188475", "188490"]}; $.post("api/Orders/OrderFromInventory?" + $.param(params)) and the Controller action: public HttpResponseMessage OrderFromInventory(IList<int> InvItemIDs) { return new HttpResponseMessage(); } I've built the query string so that it's sending: ?InvItemIDs=188475&InvItemIDs=188490 as well as ?InvItemIDs[]=188475&InvItemIDs[]=188490 and even ?InvItemIDs[0]=188475&InvItemIDs[1]=188490 and none of them are binding. InvItemIDs is always null. What am I doing wrong? EDIT: So it turns out all this is a bug (or something) in the new Web API controller code in MVC4. As soon as I moved the exact same code over to a standard controller it started working. I'm still interested if anyone has any insight as to why the Web API would break this binding.

  • How to pass a variable through url and use it inside a controller

I have another ActionResult just like this except taking in an int id as parameter and it works fine with the first url format.

  • Enum.TryParse with Flags attribute

    - by Sunny
    I have written code to TryParse enum either by value or by its name as shown below. How can I extend this code to include parsing enums with Flags attribute? public static bool TryParse<T>(this T enum_type, object value, out T result) where T : struct { return enum_type.TryParse<T>(value, true, out result); } public static bool TryParse<T>(this T enum_type, object value, bool ignoreCase, out T result) where T : struct { result = default(T); var is_converted = false; var is_valid_value_for_conversion = new Func<T, object, bool, bool>[]{ (e, v, i) => e.GetType().IsEnum, (e, v, i) => value != null, (e, v, i) => Enum.GetNames(e.GetType()).Any(n => String.Compare(n, v.ToString(), i) == 0) || Enum.IsDefined(e.GetType(), v) }; if(is_valid_value_for_conversion.All(rule => rule(enum_type, value, ignoreCase))){ result = (T)Enum.Parse(typeof(T), value.ToString(), ignoreCase); is_converted = true; } return is_converted; } Currently this code works for the following enums: enum SomeEnum{ A, B, C } // can parse either by 'A' or 'a' enum SomeEnum1 : int { A = 1, B = 2, C = 3 } // can parse either by 'A' or 'a' or 1 or "1" Does not work for: [Flags] enum SomeEnum2 { A = 1, B = 2, C = 4 } // can parse either by 'A' or 'a' // cannot parse for A|B Thanks!

  • Can someone tell me why my dataset wont save correctly to the database in simple winforms app?

    - by Mike
    I have been struggling with this all day and I know it is probably something stupid. My code is below. If I call save then exit my program and start again I can save images to my events but if I just call save when I try to add an image and call save again I get a foreign key error. From what I know I thought my save method was updating the database from my dataset so the event associated with the image should exist. Anyway here is my save method... Private Sub Save() Me.Validate() EventsBindingSource.EndEdit() ImagesBindingSource.EndEdit() TableAdapterManager.UpdateAll(EventDataSet) EventDataSet.AcceptChanges() End Sub Am I doing this wrong? Is this enough detail?

  • HttpSessionState Where, How, Advantages?

    - by blgnklc
    You see the code below, how I did use the session variable; So the three questions are; 1- Where are they stored? (Server or Client side) 2- Are they unique for each web page visitor? 3- Can I remove it using ajax or simple js code when my job is done with it? or it will be removed automatically..? sbyte[][] arrImages = svc.getImagesForFields(new String[] { "CustomerName", "CustomerSurName" }); Dictionary<string, byte[]> smartImageData = new Dictionary<string, byte[]>(); int i = 0; foreach (sbyte[] bytes in arrImages) { smartImageData.Add(fieldNames[i], ConvertToByte(bytes)); i++; } Session.Add("SmartImageData", smartImageData);

  • Browser App - RAD UI Development - Is it possible?

    - by Randy Minder
    I've been away from building browser applications for a long time. I'm now interested in creating one for a hobby of mine. I dread having to deal with HTML, JavaScript etc. to build a high quality browser based user interface. I've got the full suite of Telerik controls. Is it possible to build a polished, somewhat feature rich browser UI while being sheltered from the archaic environment of HTML and JavaScript? I'd love to be able to simply drag-drop components, much like building a Win UI and have the exact HTML, JavaScript code created for me. Thanks!

  • What is the easiest way to deploy a MVC2 application from Visual Studio 2010 to IIS 7.5?

    - by Richard
    I´ve tried a couple of different ways to deploy a application to a IIS 7.5 running on my machine for testing purposes and i´ve sort of hit a wall. Nothing works out of the box. Everything assumes I have knowledge I don't have and would prefer not to have to aqquire. Google isn't really helping either with answers ranging from "copy files by hand" to "install teamcity and set it up for CI". I have set up TeamCity for java projects before and it's really over kill for my needs at the moment. So anyone know of a fast, simple and easy way to deploy a application during testing/building?

  • Adding Controls Programatically

    - by Mike Keller
    I have a page I need to build out where depending on the selection the user made on a form on the page prior it displays a different set of questions for them to answer. So say the user selects Reason A from the form on page edit, then it needs to display Questions 1 and 2 on page edit_confirmation. But if they select Reason B then it needs to display Questions 3 and 4. I'm grabbing the reason code from the query string and have a switch statement set up, but I can't find anywhere how to output different controls. If Questions 1 and 2 are supposed to show up, one could be a text box and the other a checkbox, but if questions 3 and 4 are supposed to show up one may need to be a dropdown list and a checkbox.
