  • WCF REST vs. ADO.NET Data Services

    - by ray247
    Hi there, Could someone compare and contrast on WCF Rest services vs. ADO.NET Data Services? What is the difference and when to use which? Thanks, Ray. Edit: thanks to the first answer, just to give a bit background on what I'm looking to do: I have a web app I plan to put in the cloud (someday), the DAL is built with ADO.NET Entity Framework. And, I need to figure which web service data access technology would best fit my case.

  • Multiple skins in ASP.NET MVC using StringTemplate

    - by Jamie
    I am considering the StringTemplate view engine for my ASP.NET MVC application. This application will be built with one skin, but I then expect many more, often very similar skins to be developed for it. This is primiarly the reason for my choice of StringTemplate as the view engine, as there will be zero logic in the views. In my head, I envisaged having each skin in a directory under the 'Views' directory in the folder structure, then maintaining a data structure which maps hostnames to skin directories. An obvious disadvantage of this approach is that I will have to explicitly specify my view files - an alternative might be to hack the implementation of the View() method to change the /views/controller/action standard path and insert an extra layer. Is anyone aware of any examples of implementations along these lines using ASP.NET MVC and StringTemplate at present? Can anyone forsee any potential problems with my approach? Thanks in advance.

  • Random "Not Found" error with Silverlight accessing ASP.NET Web Services

    - by user245822
    I'm developing an application with Silverlight 3 and ASP.NET Web Services, which uses Linq to SQL to get data from my SQL Server database. Randomly when the user causes an action to get information from any of my web service methods, Silverlight throws the exception "The remote server returned an error: NotFound.", of type "CommunicationException", with the InnerException status of "System.Net.WebExceptionStatus.UnknownError". Almost 10% of requests gets this error. If the user tries to get the same information again, normally the request has no erros and the user gets the data. When debugging in Visual Studio only Silverlight stops on the exception, and I see no reason for the web service not being found.

  • MVP on Asp.Net WebForms

    - by Nicolas Irisarri
    I'm not clear about this.... When having a gridview on the View, is the controller who has to set up the Data source, columns, etc? or I just have to expose the DataBinding stuff, fire it from the controller and let the html/codebehind on the view handle all the rendering and wiring up? To be more precise: on the view should I have private GridView _gv public _IList<Poco> Source { get {_gv.DataSource;} set {_gv.DataSource = value; _gv.DataBind();} } Or should it be (from http://stackoverflow.com/questions/153222/mvp-pattern-passive-view-and-exposing-complex-types-through-iview-asp-net-web) private GridView _datasource; public DataSource { get { return _datasource; } set { _datasource = value; _datasource.DataBind(); } } Maybe I'm having it all wrong .... Where can I find an example that is not a "Hello world" example on MVP for ASP.Net???

  • Integrating FedEx Web Services into .Net, stuck at step 1

    - by Matt Dawdy
    I'm signed up, I've downloaded sample code, I've got a WSDL...and yet I have no idea how to get this stuff into my existing .Net application. The WSDL was in a zip file, not a URL so I can't just "Add Web Reference." I've run the wsdl tool from the .Net command prompt, and it made a nice class for me...yet dropping that into my web_reference folder doesn't give me any kind of instantiatable class. I know I'm missing something stupid. Can someone point me in the right direction please?

  • Debugging ASP.NET Strings Downloaded to Browser (Montréal instead of Montréal)

    - by jdk
    I'm downloading a vCard to the browser using Response.Write to output .NET strings with special accented characters. Mime type is text/x-vcard and French characters are appearing wrong in Outlook, for example Montréal;Québec .NET string shows as Montréal Québec in browser. I'm using this vCard generator code from CodeProject.com I've played with the System.Encoding sample code at the bottom of this linked MSDN page to convert the unicode string into bytes and then write the ascii bytes but then I get Montr?al Qu?bec (progress but not a win). Also I've tried setting content type to both us-ascii and utf-8 of the response. If I open the downloaded vCard in Windows Notepad and save it as ANSI text (instead of default unicode format) and open in Outlook it's okay. So my assumption is I need to cause download of ANSI charset but am unsure if I'm doing it wrong or have a misunderstanding of where to start. Update: Looking at the raw HTTP, it appears my French characters are being downloaded in the unexpected format so it looks like I need to do some work on the server side... (full size)

  • protobuf-net - backticks, Dictionaries & .proto files

    - by JosephH
    I'm trying to talk to a C# program that uses protobuf-net from an iphone using http://code.google.com/p/metasyntactic/wiki/ProtocolBuffers Unfortunately the .proto file I've been given (generated from the C# source code) includes an a line that protoc is rejecting: repeated Pair_Guid_List`1 Local = 6; It appears that this is because the source data is a C# Dictionary, with a Guid key and a class as the value. Is there a way to cope with this better? The protobuf-net version in use is r278.zip. (The C# sending and receiving these protobufs all works fine, it's just when we add the iphone into the mix that this becomes an issue.)

  • WCF: WSDL-first approach: Problems with generating fault types

    - by Juri
    Hi, I'm currently in the process of creating a WCF webservice which should be compatible with WS-I Basic Profile 1.1. I'm using a wsdl-first approach (actually for the first time), defining first the xsd for the complex types, the WSDL and then using svcutil.exe for generating the according server as well as client-side interfaces/proxies. So far everything works fine. Then I decided to add a fault to my WSDL. Regenerating with svcutil succeeded, but then I noticed that my generated fault doesn't have the properties I defined in my xsd file (which is imported by my WSDL). Fault XSD definition <?xml version="1.0" encoding="UTF-8"?> <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://product.mycompany.com/groupsfault_v1.xsd" xmlns:tns="http://product.mycompany.com/groupsfault_v1.xsd"> <complexType name="groupsFault"> <sequence> <element name="code" type="int"/> <element name="message" type="string"/> </sequence> </complexType> </schema> Generated .Net fault object [System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")] [System.Xml.Serialization.XmlSchemaProviderAttribute("ExportSchema")] [System.Xml.Serialization.XmlRootAttribute(IsNullable=false)] public partial class groupFault : object, System.Xml.Serialization.IXmlSerializable { private System.Xml.XmlNode[] nodesField; private static System.Xml.XmlQualifiedName typeName = new System.Xml.XmlQualifiedName("groupFault", "http://sicp.services.siag.it/groups_v1.wsdl"); public System.Xml.XmlNode[] Nodes { get { return this.nodesField; } set { this.nodesField = value; } } public void ReadXml(System.Xml.XmlReader reader) { this.nodesField = System.Runtime.Serialization.XmlSerializableServices.ReadNodes(reader); } public void WriteXml(System.Xml.XmlWriter writer) { System.Runtime.Serialization.XmlSerializableServices.WriteNodes(writer, this.Nodes); } public System.Xml.Schema.XmlSchema GetSchema() { return null; } public static System.Xml.XmlQualifiedName ExportSchema(System.Xml.Schema.XmlSchemaSet schemas) { System.Runtime.Serialization.XmlSerializableServices.AddDefaultSchema(schemas, typeName); return typeName; } } Is this ok?? I'd expect to have an object created that contains properties for "code" and "message" s.t. you can then throw it by using something like ... throw new FaultException<groupFault>(new groupFault { code=100, message="error" }); ... (sorry for the lower-case type definitions, but this is generated code from the WSDL) Why doesn't the svcutil.exe generate those properties?? Some sources on the web suggested to add the /useSerializerForFaults option. I tried it, it doesn't work giving me an exception that the fault type is missing on the wsdl:portType declaration. Validation with several other tools succeeded however. Any help is VERY appreciated :) thx

  • How to use PDFBox 1.0 in .net / C# environment using IKVM

    - by Evan
    Id like to use PDFBox to generate PDF highlight files in my .net project. PDFBox states that it can be used in .net via IKVM http://www.pdfbox.org/userguide/dot_net.html BUT running ikvmc (latest version) to generate the DLLs on PDFBOX.1.0.0.jar generates a whole lot of NoClassDefFound warnings. How should I fix this, and what other DLLs do I need to include in my project? It seems as though file names have changed from the older documentation/articles I have read on the matter. thanks in advance.

  • .net activeX object

    - by Ali YILDIRIM
    Hi, I am trying to use my .net image editor user control as an activeX object in a web form. After internet search, I created a asp.net web site from VS2008 and added the following code <object classid="res/ImageEditor.dll#ImageEditor.Editor" height="400" width="400" id="myControl1" name="myControl1" > </object> <INPUT id="Button1" type="button" value="Btn" name="Btn" onclick="return Button1_onclick()"> </script> <script language=javascript> function Button1_onclick() { alert(document.getElementById("myControl1").WatermarkText); } </script> I have two problems 1-) When i first create the project i see the user control on browser but, after rebuilding the user control and changing the dll file at web site, the object no more appears on browser. Instead i see something like an error image. 2-) i can not access public properties. The user control is marked as "make com visible", and register for com is checked at properties.

  • Asp.net RenderControl method not rendering autopostback for dropdownlist

    - by Tanya
    Hi all, i am bit confused as to why asp.net does not render a dropdownlist with the autopostback property set to true when using the RenderControl method. eg Dim sw As New IO.StringWriter Dim tw As New HtmlTextWriter(sw) Dim table As New Table table.Rows.Add(New TableRow) Dim tr As TableRow = table.Rows(0) tr.Cells.Add(New TableCell) Dim tc As TableCell = tr.Cells(0) Dim ddlMyValues As New DropDownList ddlMyValues.ID = "ddl1" ddlMyValues.Items.Add("Test1") ddlMyValues.Items.Add("Test2") ddlMyValues.Items.Add("Test3") ddlMyValues.AutoPostBack = True tc.Controls.Add(ddlMyValues) table.RenderControl(tw) Debug.WriteLine(sw.ToString) my output renders the dropdown list without the onchange="javascript:setTimeout('__doPostBack(\ddl1\',\'\')', 0)" that is generated by asp.net when using the dropdownlist normally. Is there a work around to this?

  • Response.TransmitFile() with UNC share (ASP.NET)

    - by frankadelic
    In the comments of this page: http://msdn.microsoft.com/en-us/library/12s31dhy.aspx ..it says that TransmitFile() cannot be used with UNC shares. As far as I can tell, this is the case; I get this error in Event Log when I attempt it: TransmitFile failed. File Name: \\myshare1\e$\file.zip, Impersonation Enabled: 0, Token Valid: 1, HRESULT: 0x8007052e The suggested alternative is to use WriteFile(), however, this is problematic because it loads the file into memory. In my application, the files are 200MB, so this is not going to scale. Is there a method in ASP.NET for streaming files to users that's: scalable (doesn't read entire file into RAM or occupy ASP.NET threads) works with UNC shares Mapping a network drive as a virtual directory is not an option for us. I would like to avoid copying the file to the local web server as well. Thanks

  • Thrift and .NET - Is this is right combination?

    - by Vadi
    I've been evaluating various technologies for a Social Networking project. The Thrift kind of interested me to evaluate. The advantage I see using Thrift is I can even come with C++ services when the computation in any such business is huge and may not fits with .NET etc., Please suggest your comments. My Questions: Is the open-sourced one is production-ready? Is it the right stack for services layer to choose when the application (GUI) is primarily gets developed in ASP.NET and DB is SQL Server? Is there any other caveats

  • Most popular classroom, bootcamp, or online training for ASP.NET 3.5

    - by Curtis White
    What are the most popular and highest quality training sources for ASP.NET 3.5. I am interested in both "boot camp" class room training and online self-paced training. I am interested in both training that can be applied to certification but also non certification based training in the following areas: ASP.NET 3.5, AJAX, and web security. The training should be geared to real world projects and not memorization. I am most interested to hear from Microsoft MVP's on the matter and those who personally have attended or scheduled such training.

  • How to use HTML-5 data-* attributes in ASP.NET MVC

    - by sleepy
    I am trying to use HTML5 data- attributes in my ASP.NET MVC 1 project. (I am a C# and ASP.NET MVC newbie.) <%= Html.ActionLink("« Previous", "Search", new { keyword = Model.Keyword, page = Model.currPage - 1}, new { @class = "prev", data-details = "Some Details" })%> The "data-details" in the above htmlAttributes give the following error: CS0746: Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access. It works when I use data_details, but I guess it need to be starting with "data-" as per the spec. My questions: Is there any way to get this working and use HTML5 data attributes with Html.ActionLink or similar Html helpers ? Is there any other alternative mechanism to attach custom data to an element? This data is to be processed later by JS.
