  • ASP.NET web site running in IIS and hosting WCF service fails to get connections on the TCP server

    - by Salil
    I am using the combination of Silverlight client application along with ASP.NET web site running in IIS and hosting WCF service. This WCF service uses the library that starts a TCP server and and initiates requests to the connected TCP clients when the silverlight client application makes the WCF async requests. When I use this library in a local WPF application, the TCP server is able to receive client connection requests and I can get info from these clients. But when I use the same library from the implementation of the WCF service inside the ASP .NET web site project (+ Silverlight client), the server strangely does not receive any connection requests i.e. when I create TcpListener object and issue a start, nothing happens (nor an exception is generated). My setup is I am using the Ethernet for the Internet and Wi-Fi for the TCP clients. Is the WCF service getting confused because of this? Is there any special WCF settings I should put in for TcpListener.Start to work?

  • Asp.Net (C#) MVC Routing - Trying avoid using the same controller in different places and think rout

    - by sheefy
    Hi Guys, I'm currently building a site which has a bunch of main categories and in each category you can perform a search. Basically, I want my addresses to work like this... When the website loads (as in when someone goes to www.mySite.com) it will redirect them to the default category. www.mySite.com/Category Then when you search within a category, the results would come up in a page like the following. www.mySite.com/Category/Search I want to put everything in one controller and have one main view for the Category and one for the Search, I would then render these based on which category is currently being viewed. Can this be done, maybe with routing? I don't want to have to create a different controller for each category as it's just duplicating a lot of the code. Thanks in advance for your help.

  • Working with three dimensional data in an HTML (ASP.NET) table.

    - by ProfK
    I am working on the prototype for a scheduling application on an intranet system. The application is for scheduling and tracking promotional workers at various locations on various dates (hence location, date, workers dimensions). Currently, only for prototyping, I am generating a data table of location/date, and from this I iteratively build an HTML table (asp:Table control). On visiting each cell, I query for people working that location-date and populate the cell accordingly. This is very inefficiant, and will at worst be improved by querying cached data for the whole location/date grid. I'm looking around for established patterns and techniques for dealing with scenarios like this in HTML in general, maybe a visualisation library for jQuery or something, and for ASP.NET in particular, maybe a library for implementation on a GridView etc. Am I going in the right direction with this, and if so, what recomendations are there regarding the previous paragraph?

  • Pass object from JSON into MVC Controller - its always null ?

    - by SteveCl
    Hi I have seen a few questions on here related to the a similar issue, I have read them, followed them, but still i have the same problem. I am basically creating an object in javascript and trying to call a method on the controller that will return a string of html. Not JSON. I've been playing around with dataType and contentType but still no joy. So apologies if the code snippets are a bit messy. Build the object in JS. function GetCardModel() { var card = {}; card.CardTitle = $("#CardTitle").val(); card.TopicTitle = $("#TopicTitle").val(); card.TopicBody = $("#TopicBody").data("tEditor").value(); card.CardClose = $("#CardClose").val(); card.CardFromName = $("#CardFromName").val(); return card; } Take a look at the object - all looks good and as it should in JSON. var model = GetCardModel(); alert(JSON.stringify(GetCardModel())); Make the call... $.ajax({ type: "POST", url: "/Postcard/Create/Preview/", dataType: "json", //contentType: "application/json", date: GetCardModel(), processData: true, success: function (data) { alert("im back"); alert(data); }, error: function (xhr, ajaxOptions, error) { alert(xhr.status); alert("Error: " + xhr.responseText); //alert(error); } }); Always when I step into the controller, the object is ALWAYS there, but with null values for all the properties.

  • Typed DataSet connection - required to have one in the .xsd file?

    - by Kyralessa
    In the .xsd file for a typed DataSet in .NET, there's a <Connections> section that contains a list of any data connections I've used to set up the DataTables and TableAdapters. There are times when I'd prefer not to have those there. For instance, sometimes I prefer to pass in a connection string to a custom constructor and use that rather than look for one in settings, .config, etc. But it seems like if I remove the connection strings from that section (leaving it empty), or remove the section entirely, the DataSet code-generation tool freaks out. Whereas if I don't remove them, the DataSet gripes when I put it in a different project because it can't find the settings for those connection strings. Is there any way I can tell a typed DataSet not to worry about any connections? (Obviously I'll have to give it a connection if I change any TableAdapter SQL or stored procs, but that should be my problem.)

  • What is your prefered way to return XML from an ActionMethod in Asp.net MVC?

    - by serbrech
    I am displaying charts that load the data asynchronously because the searches are the work to fetch the data is quite heavy. The data has to be return as XML to make the chart library happy. My ActionMethods return a ContentResult with the type set as text/xml. I build my Xml using Linq to XML and call ToString. This works fine but it's not ideal to test. I have another idea to achieve this which would be to return a view that builds my XML using the XSLT View engine. I am curious and I always try to do the things "the right way". So how are you guys handling such scenarios? Do you implement a different ViewEngine (like xslt) to build your XML or do you Build your XML inside your controller (Or the service that serves your controller)?

  • How to Not alter font in webpage after opening a file (pdf or jpg) in ASP.NET C#? [closed]

    - by Victor
    Possible Duplicate: How to not alter font in webpage after opening a pdf in ASP.NET C#? Previously I posted this question: How to open files from a specific route in ASP-NET c#? in fact, I have already asked this however it was only a minor question so I guess it wasn't that important in the previous post, so I will ask here. Whenever I open a pdf with: Response.Write("<script>window.open('FilePath');</script>"); All of the font in the page is altered, example, the letter's size increases and some of the letter's colors are switched to black instead of the font that I assigned. Is there a way that I can work around that?? http://imageshack.us/a/img838/5145/beforeja.png http://imageshack.us/a/img546/4760/afterw.png Oh and I noticed that this also happens when you open images like jpg

  • T4MVC Optional Parameter Inferred From Current Context

    - by Itakou
    I have read the other post about this at T4MVC OptionalParameter values implied from current context and I am using the latest T4MVC (2.11.1) which is suppose to have the fix in. I even checked checked to make sure that it's there -- and it is. I am still getting the optional parameters filled in based on the current context. For example: Let's say I have a list that is by default ordered by a person's last name. I have the option to order by first name instead with the URL http://localhost/list/stuff?orderby=firstname When I am in that page, I want to go back to order by first name with the code: @Html.ActionLink("order by last name", MVC.List.Stuff(null)) the link I wanted was simply http://localhost/list/stuff without any parameters to keep the URL simple and short - invoking default behaviors within the action. But instead the orderby is kept and the url is still http://localhost/list/stuff?orderby=firstname Any help would be great. I know that in the most general cases, this does remove the query parameter - maybe I do have a specific case where it was not removed. I find that it only happens when I have the URL inside a page that I included with RenderPartial. My actual code is <li>@Html.ActionLink("Recently Updated", MVC.Network.Ticket.List(Model.UI.AccountId, "LastModifiedDate", null, null, null, null, null))</li> <li>@Html.ActionLink("Recently Created", MVC.Network.Ticket.List(Model.UI.AccountId, "CreatedDate", null, null, null, null, null))</li> <li>@Html.ActionLink("Most Severe", MVC.Network.Ticket.List(Model.UI.AccountId, "MostSevere", null, null, null, null, null))</li> <li>@Html.ActionLink("Previously Closed", MVC.Network.Ticket.List(Model.UI.AccountId, "LastModifiedDate", null, "Closed", null, null, null))</li> the problem happens when someone clicks Previously Closed and and go to ?status=closed. When they click Recently Updated, which I want to the ?status so that it shows the active ones, the ?status=closed stays. Any insight would be greatly appreciated.

  • Single Sign On with 3 applications

    - by John H.
    I'm building three web applications in .NET that will all share a users database and login information. Lets pretend that application 1 is the "parent" application and applications "A" and "B" are the "child" applications. All users have to be logged into application 1 to have access to applications A and B. Authorization, Authentication, and MachineKey sections of all web configs are present and work correctly. I have the correct web.config settings in all applications to achieve Single Sign On except one problem remains: what do I put in the "loginUrl" attribute of the forms tag in Applications A and B. Assume that the url for the login to application 1 is "www.johnsapp.com/login.aspx" How can I get applications A and B to send the user back to application 1 for authentication using only settings in web.config?

  • Can I add a spring mvc filter using jetty with a jar file?

    - by Juan Manuel
    I have a simple web application disguised as a java application (as in, it's a .jar instead of a .war), and I'd like to use a filter for my requests. If it was a .war, I could initialize it with a WebAppContext and specify a web.xml file where I'd have my filter declaration like this <filter> <filter-name>myFilter</filter-name> <filter-class>MyFilterClass</filter-class> </filter> <filter-mapping> <filter-name>myFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> However, I'm using a simple Context to initialize my application with Spring. Server server = new Server(8082); Context root = new Context(server, "/", Context.SESSIONS); DispatcherServlet dispatcherServlet = new DispatcherServlet(); dispatcherServlet.setContextConfigLocation("classpath:application-context.xml"); root.addServlet(new ServletHolder(dispatcherServlet), "/*"); server.start(); Is there a way to programmatically specify filters for the spring servlet, without using a web.xml file?

  • What are the differences between MVP, Presentation Model, MVVM and MVC?

    - by Nicholas
    I have a pretty good idea how each of these patterns work some of the minor differences between them, but are they really all that different from each other? It seems to me that the Presenter, Presentation Model, ViewModel and Controller are essentially the same concept. Why couldn't I classify all of these concepts as controllers? I feel like it might simplify the entire idea a great deal. Can anyone give a clear description of their differences? I want to clarify that I do understand how the patterns work, and have implemented most of them in one technology or another. What I am really looking for is someone's experience with one of these patterns, and why they would not consider their ViewModel a controller for instance.
