  • Deploying Asp.Net MVC 2 /C# 4.0 application on IIS 6

    - by Mose
    Hi, I got a problem migrating from VS.Net 2008 / MVC 1 to VS.NET 2010 (+C# 4.0) / MVC 2 The web.config has been updated, the site runs well in Cassini, but my problem now is deploying on IIS 6. I updated the web site to run using ASP.Net 4, but whatever URL I try, I always have a 404 error. It's as if the routing was not taken into account (yes, the wildcard mapping has been done). I do not understand this mess and could not google anything interesting... Thanks for your suggestions ! O.

  • Most used .NET namespace

    - by Michael Prewecki
    What is your most commonly used namespace in .NET. I know it will vary greatly based upon the types of projects you develop but the stack overflow audience should provide a fairly decent sample set for the types of .NET projects being developed. I'm simply interest in the name of the namespace (one namespace per answer and no one person should have more than one answer, if someone else has the same answer as you then just upvote their answer). Try to be as specific as possible (so answering System, isn't helpful). I'm after this information to help new developers focus their attention on the most common .NET namespaces...there are after all thousands of them! To start off mine is almost certainly System.Collections.Generic, I use lists of things everywhere.

  • How should I provide access to this custom DAL?

    - by Casey
    I'm writing a custom DAL (VB.NET) for an ordering system project. I'd like to explain how it is coded now, and receive some alternate ideas to make coding against the DAL easier/more readable. The DAL is part of an n-tier (not n-layer) application, where each tier is in it's own assembly/DLL. The DAL consists of several classes that have specific behavior. For instance, there is an Order class that is responsible for retrieving and saving orders. Most of the classes have only two methods, a "Get" and a "Save," with multiple overloads for each. These classes are marked as Friend and are only visible to the DAL (which is in it's own assembly). In most cases, the DAL returns what I will call a "Data Object." This object is a class that contains only data and validation, and is located in a common assembly that both the BLL and DAL can read. To provide public access to the DAL, I currently have a static (module) class that has many shared members. A simplified version looks something like this: Public Class DAL Private Sub New End Sub Public Shared Function GetOrder(OrderID as String) as OrderData Dim OrderGetter as New OrderClass Return OrderGetter.GetOrder(OrderID) End Function End Class Friend Class OrderClass Friend Function GetOrder(OrderID as string) as OrderData End Function End Class The BLL would call for an order like this: DAL.GetOrder("123456") As you can imagine, this gets cumbersome very quickly. I'm mainly interested in structuring access to the DAL so that Intellisense is very intuitive. As it stands now, there are too many methods/functions in the DAL class with similar names. One idea I had is to break down the DAL into nested classes: Public Class DAL Private Sub New End Sub Public Class Orders Private Sub New End Sub Public Shared Function Get(OrderID as string) as OrderData End Function End Class End Class So the BLL would call like this: DAL.Orders.Get("12345") This cleans it up a bit, but it leaves a lot of classes that only have references to other classes, which I don't like for some reason. Without resorting to passing DB specific instructions (like where clauses) from BLL to DAL, what is the best or most common practice for providing a single point of access for the DAL?

  • Decrypting PKCS#7 encrypted data in C#

    - by Johnny Egeland
    I am working on a solution that needs to decrypt PKCS#7 encrypted data, preferably in C#. As far as I can see, the .NET api has support for this through the System.Security.Cryptography.Pkcs namespace. However it seems that the implementation can only work on byte arrays. So what do I do when I have a large encrypted file that does not fit into the memory? Am I missing something here, or is there another way to do this on a Stream level instead of using bytearrays?

  • Loginview control asp.net mvc

    - by vikitor
    Hello all, I have been searching and haven't got luck, I got a tutorial to use the loginview control in order to display or hide parts of the views to different user roles in my application. The thing is that the tutorial I've found is for ASP.NET and I've been told by one of my colleages that it is the same framework for ASP.NET MVC but the way to use it is different. Have you got any good tutorial to recommend? EDIT: I've got all my application set up, and the login and the roles already configured (via asp.net membership provider). This is all already running. The thing is that if I have role a and role b I want role a to be able to actually see the links to the actions it is authorized to work with, and not b for example. If in the Index of my application I've got a link to "Edit" and only the role a can access to the action, then it will be displayed just for logged in users that belong to role a, and not to those who belong to role b Thank you, Vikitor

  • Silverlight Cannot find XML data source

    - by Nick
    Hello.. I am very new to Silverlight development. I understand that this is client side technology therefore the paradyme is differant from that of conventional ASP.NET development. Having said that, I don't understand where my server side code is deployed. I have a silver light \ MVC application. I am trying to read an XML document from within my 'Models' folder. The following peice of code is executed from within a class that is in the same location as the XML document, 'Models'. The load() results in a SystemIOFileNotFound exception. I noticed that when building the application the XML document is not laid down in the same location as the web project's assembly. I assume this is specific to the fact that this is a Silverlight project. Can someone tell me what I'm missing? _xdoc = new XDocument(); _xdoc = XDocument.Load(new Uri("videos.xml",UriKind.Relative).ToString());

  • Using C# and VB.NET in one solution

    - by Younes
    I'm busy on a small project to convert an Access2003 db to .NET. I am trying to integrate my functionality in an excisting project that is being used for Administration of some kind. The code in this project is vb.net. I started by setting up my Data Access Layer, which seems to work fine. I can make new web pages that acces the data I need. However when i start to use class files to set up my Business Logic Layer i can't build my project when using C# instead of VB. I Dislike VB and like to program in C# as i know the syntax alot better etc. Is it possible to program using C# knowing that VB.NET was the language chosen to buold the entire project on? If not, what will be the smartest way to integrate my module into the project using my favorite programming language? (Make a project and reference to the dll?)

  • ASP.NET MVC as a service host for SOA like architecture

    - by Delucia
    I'm creating a distributed application that includes a lot of services and I'm looking for the technology that allows me to create and manage a lot of services easily. I know managing and deploying windows services is not fun. I'm thinking of using ASP.NET MVC as service host of my services where each controller action becomes essentially a service and I can communicate with a service via simple HTTP request and responses and not have to deal with complexity if i use something like WCF. Services need to be isolated and asp.net requests are isolated as far as i know, i.e. if a request throws an exception it will not effect other running requests. But I still have questions about the management of the services. How will it be possible to see which services are running, stopping and resuming services. Also ASP.NET MVC are passive, i.e. they only do something upon a request but what if i want to service that initiates work by itself?

  • Unable to send email on production server with ASP.NET MVC

    - by Davide Vosti
    I have a simple ASP.NET MVC application with a contact page. In my development machine (local) I can send successfully emails (I specify host and credentials), but on the production server this doesn't work and I get this error: System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: Requested action not taken: mailbox unavailable or not local at System.Net.Mail.SmtpTransport.SendMail... The server is in my LAN (the mail server too). I tried with multiple accounts but I have errors every time. Credentials for the account are provided at runtime with smtp.Credentials = new NetworkCredential("username", "password"); Any idea? Thanks

  • Best 3D Graphics Engine for .NET

    - by George Stocker
    I've been thinking about tinkering with 3D graphics programming in .NET. In the past, I've thought about Truevision3D, and XNA, but I've not used either of these. I scanned Stackoverflow for the exact question, but neither of the (almost) relevant question (such as this question about rendering graphics, and this question about Learning Game Programming) answer my specific question. Out of the graphics engine APIs you've used for .NET, which is the easiest to use, which has the most features, and which is the cheapest? Which would you recommend for a .NET programmer to learn first?

  • .NET : Targeting the runtime

    - by contactmatt
    I'm starting to read in-depth on the .NET framework, and its Common Language Runtime. I'm reading a .NET overview by Microsoft and I'm not sure what is meant by this statement. Code that targets the runtime is known as managed code, while code that does not target the runtime is known as unmanaged code. How do you target the Common Language Runtime? I know its defaulted when developing in Visual Studio, but how would you specifically target the CLR? What code when developing a .NET application wouldn't target the CLR, and thereby be called unmanaged code?

  • AES Encryption. From Python (pyCrypto) to .NET

    - by Why
    I am currently trying to port a legacy Python app over to .NET which contains AES encrpytion using from what I can tell pyCrpyto. I have very limited Python and Crypto experience. The code uses the snippet from the following page. http://www.djangosnippets.org/snippets/1095/ So far I believe I have managed to work out that it that it calls Crypto.Cipher with AES and the first 32 character of our secret key as the password, but no mode or IV. It also puts a prefix on the encrpyed text when it is added to database. What I can't work out is how I can decrypt the existing ecrypted database records in .NET. I have been looking at RijndaelManaged but it requires an IV and can't see any reference to one in python. Can anyone point me in the dirrection to what method could be used in .NET to get the desired result.

  • Change Visual Studio Default Browser in an ASP.NET MVC project

    - by Kirschstein
    FireFox is set to my Windows default browser. I want to change the default browser used by Visual Studio for debugging. Normally the route I'd take to do this is right clicking on an .aspx file and setting the default from the Browse With... dialog. Unfortunately, ASP.NET MVC Views don't have the Browse With... option. What other ways can you set the default browser for ASP.NET MVC projects? Related, but NOT ASP.NET MVC Specific: Visual Studio opens default browser instead of IE

  • WCF web service Data Members defaulting to null

    - by James
    I am new to WCF and created a simple REST service to accept an order object (series of strings from XML file), insert that data into a database, and then return an order object that contains the results. To test the service I created a small web project and send over a stream created from an xml doc. The problem is that even though all of the items in the xml doc get placed into the stream, the service is nullifying some of them when it receives the data. For example lineItemId will have a value but shipment status will show null. I step through the xml creation and verify that all the values are being sent. However, if I clear the datamembers and change the names around, it can work. Any help would be appreciated. This is the interface code [ServiceContract] public interface IShipping { [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "/Orders/UpdateOrderStatus/", BodyStyle=WebMessageBodyStyle.Bare)] ReturnOrder UpdateOrderStatus(Order order); } [DataContract] public class Order { [DataMember] public string lineItemId { get; set; } [DataMember] public string shipmentStatus { get; set; } [DataMember] public string trackingNumber { get; set; } [DataMember] public string shipmentDate { get; set; } [DataMember] public string delvryMethod { get; set; } [DataMember] public string shipmentCarrier { get; set; } } [DataContract] public class ReturnOrder { [DataMember(Name = "Result")] public string Result { get; set; } } This is what I'm using to send over an Order object: string lineId = txtLineItem.Text.Trim(); string status = txtDeliveryStatus.Text.Trim(); string TrackingNumber = "1x22-z4r32"; string theMethod = "Ground"; string carrier = "UPS"; string ShipmentDate = "04/27/2010"; XNamespace nsOrders = "http://tempuri.org/order"; XElement myDoc = new XElement(nsOrders + "Order", new XElement(nsOrders + "lineItemId", lineId), new XElement(nsOrders + "shipmentStatus", status), new XElement(nsOrders + "trackingNumber", TrackingNumber), new XElement(nsOrders + "delvryMethod", theMethod), new XElement(nsOrders + "shipmentCarrier", carrier), new XElement(nsOrders + "shipmentDate", ShipmentDate) ); HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:3587/Deposco.svc/wms/Orders/UpdateOrderStatus/"); request.Method = "POST"; request.ContentType = "application/xml"; try { request.ContentLength = myDoc.ToString().Length; StreamWriter sw = new StreamWriter(request.GetRequestStream()); sw.Write(myDoc); sw.Close(); using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { StreamReader reader = new StreamReader(response.GetResponseStream()); string responseString = reader.ReadToEnd(); XDocument.Parse(responseString).Save(@"c:\DeposcoSvcWCF.xml"); } } catch (WebException wEx) { Stream errorStream = ((HttpWebResponse)wEx.Response).GetResponseStream(); string errorMsg = new StreamReader(errorStream).ReadToEnd(); }

  • JSP/JSF conversion to ASP.NET

I already converted the Java code to C# code manually and also using JCLA (Java Language Conversion Assistant from Microsoft). What is the best way to convert the JSF part to ASP.NET? Is there any tool that can help shorten the work? For example convert JSF <t:dataList> to ASP.NET datagrid, or converting panelGroup to asp:panel, etc...

  • Sharing ASP.NET State databases between multiple apps

    - by MikeWyatt
    Is it better for a collection of ASP.NET web apps to share the same session database, or should each one have its own? If there is no significant difference, having a single database would be preferable due to easier maintenance. Background My team has an assortment of ASP.NET web apps, all written in either Monorail 1.1 or ASP.NET MVC 1.0. Each app currently uses a dedicated session state database. I'm working on adding a new site to that list, and am debating whether I should create another new session database, or just share an existing one with another app.

  • .Net opening and closing database connections

    - by Dan
    I designed the data access portion of our framework so that every time a business object needs to interact with the database it would have to open a connection, invoke the data access layer (to execute the query), and then close the connection. Then if it needed to run in a transaction it would open the connection, begin the transaction, invoke the data access layer (to execute the query) and then commit the transaction, close the transaction, and finally close the connection. I did it this way with the mindset of open late and close early... but what if I needed to call other BO's to submit data in a single transaction? Is there a better way to handle opening and closing connections as well as working with transactions? I'm a rookie in designing application architecture so I hope I'm not doing this wrongly... any help is appreciated.

  • Access to variables in an asp.net user control vs an include file

    - by user204588
    I've asked this question before but couldn't get the answer I was looking for so I'm going to try it again. I'm translating pages from old asp to asp.net and I don't want to do this any other way so I really just want to know if this can be done. In asp, I'd assign a variable on one page <% myVar = "something" %> I could assign many variables here and then use an include <!--#include file="Test2.aspx"--> then in test2 file, I could access all the variables without having to pass all the variables into the control or declaring them again, like <% myVar = "something else" %> I want to do this the dot net way but I have some thirty variables on the page and i don't want to pass a bunch into the user control and I don't want to have to keep declaring the same variables. All I really want to know is if there is some way to replicate the behavior above in asp.net?

  • WCF without NET 3.0

    - by Murat
    Hello there, Does anyone tell me if it's possible to use WCF without .NET 3.0? Our company develops a 3-tier client-server end-user solution based on .Remoting. One of the limitation of our project is using .NET 2.0. Unfortunately .NET 3.0 framework is too large to be included in our installation package and I don't know if MS license allows this. But WCF might helps us to drastically reduce our efforts in some tasks. Does anyone have a chance to use WCF from Mono? Thanks in advance -- Murat
