    - by Paul Suart
    I have the following route: routes.MapRoute( "Search", // Route name "Search/{affiliateId}", // URL with parameters new { controller = "Syndication", action = "Search" } // Parameter defaults ); Is there a way I can ensure "affiliateId" is a valid Guid?

  • ASP.NET MVC & Web Services

    - by ANaimi
    Hello, Does adding a Web Service to my ASP.NET MVC project break the whole concept of MVC? That Web Service (WCF) depends on the Model layer from my MVC project to communicate with the back-end (so it looks to me like it needs to be part of the MVC solution). Should I add this to the Controller or Model layer?

  • ASP.NET MVC : Good Replacement for User Control?

    - by David Lively
    I found user controls to be incredibly useful when working with ASP.NET webforms. By encapsulating the code required for displaying a control with the markup, creation of reusable components was very straightforward and very, very useful. While MVC provides convenient separation of concerns, this seems to break encapsulation (ie, you can add a control without adding or using its supporting code, leading to runtime errors). Having to modify a controller every time I add a control to a view seems to me to integrate concerns, not separate them. I'd rather break the purist MVC ideology than give up the benefits of reusable, packaged controls. I need to be able to include components similar to webforms user controls throughout a site, but not for the entire site, and not at a level that belongs in a master page. These components should have their own code not just markup (to interact with the business layer), and it would be great if the page controller didn't need to know about the control. Since MVC user controls don't have codebehind, I can't see a good way to do this. Update FINALLY, a good (and, in retrospect, obvious) way to accomplish this. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace K.ObjectModel.Controls { public class TestControl : ViewUserControl { protected override void Render(System.Web.UI.HtmlTextWriter writer) { writer.Write("Hello World"); base.Render(writer); } } } Create a new class which inherits ViewUserControl Override the .Render() method as shown above. Register the control via its associated ASCX as you would in a webForm: <%@ Register TagName="tn" TagPrefix="k" Src="~/Views/Navigation/LeftBar.ascx"%> Use the corresponding tag in whatever view or master page that you need: <k:tn runat="server"/> Make sure your .ascx inherits your new control: <%@ Control Language="C#" Inherits="K.ObjectModel.Controls.TestControl" %> Voila, you're up and running. This is tested with ASP.NET MVC 2, VS 2010 and .NET 4.0. Your custom tag references the ascx partial view, which inherits from the TestControl class. The control then overrides the Render() method, which is called to render the view, giving you complete control over the process from tag to output. Why does everyone try to make this so much harder than it has to be?

  • Ajax problem after deleting a div, then creating a new one

    - by Matt Nathanson
    I'm building a custom CMS where you can add and delete clients using ajax and jquery 1.4.2. My problem lies after I delete a div. The ajax is used to complete this and refresh automatically.. But when I go to create a new div (without a hard refresh) it puts it back in the slot of the div I just deleted. How can I get this to completely forget about the div i just deleted and place the new div in the next database table? link for reference: http://staging.sneakattackmedia.com/cms/ //Add New client // function AddNewClient() { dataToLoad = 'addClient=yes'; $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, target: ('#clientssidebar'), async: false, success: function(html){ $(this).click(function() {reInitialize()}); //$('#clientssidebar').html(html); $('div#' + clientID).slideDown(800); $(this).click(function() { ExpandSidebar()});}, error: function() { alert('An error occured! 222');} });}; //Delete Client // function DeleteClient(){ var yes = confirm("Whoa there chief! Do you really want to DELETE this client?"); if (yes == 1) { dataToLoad = 'clientID=' + clientID + '&deleteClient=yes', $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, success: function(html) { alert('Client' + clientID + ' should have been deleted from the database.'); $(this).click(function() {reInitialize()}); $('div#' +clientID).slideUp(800); }, error: function() { alert('error'); }});};}; //Re Initialize // function reInitialize() { $('#addnew').click(function() {AddNewClient()}); $('.deletebutton').click(function() {clientID = $(this).parent().attr('id'); DeleteClient()}) $('.clientblock').click(function() {clientID = $(this).attr('id'); ExpandSidebar()});}; //Document Ready // $(document).ready(function(){ if ($('isCMS')){ editCMS = 1; $('.deletebutton').click(function() {clientID = $(this).parent().attr('id'); DeleteClient()}); $('#addnew').click(function() {AddNewClient()}); $('.clientblock').click(function() {clientID = $(this).attr('id'); ExpandSidebar()}); $('.clientblock').click(function() {if (clickClient ==true) { $(this).css('background-image', 'url(/images/highlightclient.png)'); $(this).css('margin-left' , '30px'); }; $(this).click(function(){ $(this).css('background-image', ''); }); $('.uploadbutton').click(function(){UploadThings()}); }); } else ($('#clientscontainer')) { $('#editbutton').css('display', 'none'); }; }); Please help!!!

  • How to install Multiple ActiveX Controls per one step?

    - by Eugene
    My .ocx contains two ActiveX controls and I use both of them on one page. When user comes to page he gets two install confirmations for the same binary. After the first installation and page reload he gets one control displayed and “the website wants to run the following add-on...” yellow bar with control’s run confirmation for the other. I have only two possible solutions: Adding my CLSID’s to IE’s pre-approved control list, but I guess I cannot do it in the case of Non-Admin installation. Besides I consider this way as unreliable. Use the third control-container for hosting all other controls. It seems to my too complicated. Actually I’m not sure it can be done. Controls are used from the WEB, so I cannot use any administrative tools for installation. Is it possible to do all installation actions with one step without twice installation or run confirmation? Are there any “Best practices” for my case?

  • Active directory logonCount is 0, though the user has logged in

    - by Arun
    For a user in active directory, the properties hold values for lastlogontime & lastlogontimestamp but the logoncount is 0. I am having only one domain controller in that domain. I found from surfing, that logonCount value of 0 indicates that the value is unknown. But I am totally confused with why it is unknown. Is that an issue with AD.

  • Generating Dynamic web pages without server side scripting

    - by Microkernel
    Hi guys, I am trying to control a media device which has lot of multimedia content that it can play using another device(remote control device) like an ipad connected to the LAN. (UPnP) I want the media device to be able to send the content listing to the remote device so that it will be rendered as a webpage on the remote controller. And actions on the webpages needs to be sent to the the device as commands to execute (like play, pause, next etc). The media device is an embedded device, hence can't have any server side scripting, all has to be done on the client side. I want the page rendered to be HTML5. So, is it possible to generate dynamic HTML5 pages using just client side scripting? Thanks a lot. I am an embedded systems developer hence clueless about the web designing stuff.

  • How to run an executable as a system service?

    - by byanity
    I've got a file and data distribution application written in .NET 2.0 I've written similar to Steam. This application will need to run in Windows 7 and will need to be able to run and install applications that require administrator rights. However the users will not have admin rights. My thought was to run the application as a Local System Service. I figured by doing this the application could perform admin rights actions (registry edits, launching apps, etc) when the user isn't an admin. Are my assumptions correct? What steps do I need to take to have this app install as a Local System Service? An Administrator will be installing the application but it will be run by a user without Administrator rights. Thanks in advance!

  • I am looking for an actual functional web browser type control for .NET, maybe a C++ LIBRARY#$??$?

    - by Joshua
    I am trying to emulate a web browser in order to execute JavaScript code and then parse the DOM. The System.Windows.Forms.WebBrowser object does not give me the functionality I need. It let's me set the headers, but you cannot set the proxy or clear cookies. Well you can, but it is not ideal and messes with IE's settings. I've been extending the WebBrowser control pinvoking native windows functions so far, but it is really one hack on top of another. I can mess with the proxy and also clear cookies and such, but this control has its issues as I mentioned. I found something called WebKit .NET (http://webkitdotnet.sourceforge.net/), but I don't see support for setting proxies or cookie manipulation. Can someone recommend a c++/.NET/whatever library to do this: Basically tell me what I need to do to get an interface to similar this in .NET: string FetchBrowserParsedHtml(Uri url, WebProxy p, int timeoutSeconds, byte[] headers, byte[] postdata); void ClearCookies(); I am not responsible for my actions.

  • Creating a generic NotFound View in ASP.MVC

    - by George
    Hello guys, I'm having a problem to create a generic View to represent NotFound pages. The view is created and it's fine. I need to know how i can direct the user to the NotFound view in my Controllers and how to render a specific "Return to Index" in each controller. Here is some code: public class NotFoundModel { private string _contentName; private string _notFoundTitle; private string _apologiesMessage; public string ContentName { get; private set; } public string NotFoundTitle { get; private set; } public string ApologiesMessage { get; private set; } public NotFoundModel(string contentName, string notFoundTitle, string apologiesMessage) { this._contentName = contentName; this._notFoundTitle = notFoundTitle; this._apologiesMessage = apologiesMessage; } } // NotFound View <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Geographika.Models.NotFoundModel>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> <%= Html.Encode(Model.ContentName) %> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2><%= Html.Encode(Model.NotFoundTitle) %></h2> <p><%= Html.Encode(Model.ApologiesMessage) %></p> <!-- How can i render here a specific "BackToIndexView", but that it's not bound to my NotFoundModel? --> </asp:Content> // Controller piece of code // // GET: /Term/Details/2 public ActionResult Details(int id) { Term term = termRepository.SingleOrDefault(t => t.TermId == id); if (term == null) return View("NotFound"); // how can i return the specific view that its not bound to Term Model? // the idea here would be something like: // return View("NotFound",new NotFoundModel("a","b","c")); else return View("Details", term); } I'm not sure how to redirect to a whole different page. Can anyone give me any pointers? Thanks

  • Running ASP.NET MVC application behind a proxy with different root relative path

    - by Wiebe
    Hi All, I'm having trouble with paths in a ASP.NET MVC application that's running behind a proxy. Our IIS Application root path is for example http://server/MyApp/ meaning that all urls using the application root ("~/",Url.Action("MyAction","MyController")) are resolved to "/MyApp" Now we're running behind a proxy server that forwards all requests, but changes the application root to something like this: "/Secury/Proxy/RubbishUrl/MyApp" Because the original url is only available on the client, I thought of creating a cookie with the path prefix, and insert this before each generated URL on the server. Now the question is, what's the best location in code to modify each URL that's resolved/sent to the client (to resources, controller actions, images etc)? Every path in the application is resolved with the MVC methods (Url.Content, Url.Action etc).

  • MooTools - Programmatically fired events not working with event delegation

    - by Anurag
    Would really appreciate if anyone can help me figure out why I am unable to fire events programmatically when using event delegation in MooTools (from the Element.Delegation class). There is a parent <div> that has a change listener on some child <input> elements. When the change event is triggered by user actions, the handler on the parent div gets triggered, but when I fire it programmatically with fireEvent on any child input, nothing happens. The basic setup is: html <div id="listener"> <input type="text" id="color" class="color" /> ????????????????????????????????????????????????????????????????</div>??????????? js $("listener").addEvent("change:relay(.color)", function() { alert("changed!!"); }); $("color").fireEvent("change"); // nothing happens The event handler on the parent div does not get called. Any help is appreciated. Cheers!

  • Can the memory used by MKMapView be released some how?

    - by gdr
    I am using an MKMapView in my iPhone application. When I load this view, the activity monitor instrument shows that the real memory of my App is increasing significantly. It keeps going up as you move the map around or zoom in and out. Once the View controller that loads this view is removed, the memory that was allocated due to the usage of the mapView does not get freed up. Is there something that can be done to get all this memory back?
