  • How to host customer developed code server side

    - by user963263
    I'm developing a multi-tenant web application, most likely using ASP.NET MVC5 and Web API. I have used business applications in the past where it was possible to upload custom DLL's or paste in custom code to a GUI to have custom functions run server side. These applications were self hosted and single-tenant though so the customer developed bits didn't impact other clients. I want to host the multi-tenant web application myself and allow customers to upload custom code that will run server side. This could be for things like custom web services that client side JavaScript could interact with, or it could be for automation steps that they want triggered server side asynchronously when a user takes a particular action. Additionally, I want to expose an API that allows customers' code to interact with data specific to the web application itself. Client code may need to be "wrapped" so that it has access to appropriate references - to our custom API and maybe to a white list of approved libraries. There are several issues to consider - security, performance (infinite loops, otherwise poorly written code, load balancing, etc.), receive compiled DLL's or require raw code, etc. Is there an established pattern for this sort of thing or a sample project anyone can point to? Or any general recommendations?

  • Business Logic Layer in MVC Application

    - by Subin Jacob
    In my ASP MVC application I decided to add another Business Layer and made the model only to have properties. All other functionality like save to db, get from db is done on this new Business layer. So now the controller will be calling this business layer and model for various operations. Is it a good approach to design like this? I decided not to use model for this purpose because I would need a number of models for different actions. (for eg, one for edit and other for create)

  • Implementation review for a MVC.NET app with custom membership

    - by mrjoltcola
    I'd like to hear if anyone sees any problems with how I implemented the security in this Oracle based MVC.NET app, either security issues, concurrency issues or scalability issues. First, I implemented a CustomOracleMembershipProvider to handle the database interface to the membership store. I implemented a custom Principal named User which implements IPrincipal, and it has a hashtable of Roles. I also created a separate class named AuthCache which has a simple cache for User objects. Its purpose is simple to avoid return trips to the database, while decoupling the caching from either the web layer or the data layer. (So I can share the cache between MVC.NET, WCF, etc.) The MVC.NET stock MembershipService uses the CustomOracleMembershipProvider (configured in web.config), and both MembershipService and FormsService share access to the singleton AuthCache. My AccountController.LogOn() method: 1) Validates the user via the MembershipService.Validate() method, also loads the roles into the User.Roles container and then caches the User in AuthCache. 2) Signs the user into the Web context via FormsService.SignIn() which accesses the AuthCache (not the database) to get the User, sets HttpContext.Current.User to the cached User Principal. In global.asax.cs, Application_AuthenticateRequest() is implemented. It decrypts the FormsAuthenticationTicket, accesses the AuthCache by the ticket.Name (Username) and sets the Principal by setting Context.User = user from the AuthCache. So in short, all these classes share the AuthCache, and I have, for thread synchronization, a lock() in the cache store method. No lock in the read method. The custom membership provider doesn't know about the cache, the MembershipService doesn't know about any HttpContext (so could be used outside of a web app), and the FormsService doesn't use any custom methods besides accessing the AuthCache to set the Context.User for the initial login, so it isn't dependent on a specific membership provider. The main thing I see now is that the AuthCache will be sharing a User object if a user logs in from multiple sessions. So I may have to change the key from just UserId to something else (maybe using something in the FormsAuthenticationTicket for the key?).

  • ASP MVC.Net 3 RC2 bug ?

    - by Jarek Waliszko
    Hello, so far I've been using ASP.Net 3 BETA. Everything was working fine till the update to RC2 version. Of course I've read ScottGu's article about RC2. My problem is following. Basically I have 2 controllers: public class DynamicPageController : Controller { public ActionResult Redirect(string resource, int? pageNumber, int? id) { } } public class SystemController : Controller { public ActionResult Index() { } } In the Globals.asax I have routes like this: public static void RegisterRoutes(RouteCollection routes) { routes.MapRoute( "SystemRoute", "System/{action}", new { controller = "System", action = "Index" } ); routes.MapRoute( "PageRoute", "{resource}/{id}/{pageNumber}", new { controller = "DynamicPage", action = "Redirect", resource = UrlParameter.Optional, pageNumber = UrlParameter.Optional, id = UrlParameter.Optional } ); } In the code, I have simple link creation: System.Web.Mvc.UrlHelper u = new System.Web.Mvc.UrlHelper(context); string url = u.Action("Index", "System"); and the url is "/my_app/System" in both versions (BETA and RC2) But the code below (the syntax is the same as above, only controller and action names are different): string url = u.Action("Redirect", "DynamicPage", new RouteValueDictionary(new { resource = "Home" })); gives url which is null in RC2. It should be (and in fact in BETA was) "/my_app/Home" Why ? Is it a bug ? How can I create url for my "DynamicPage" controller ? Regards BTW: From where can I now download ASP.Mvc BETA version along with ASP.Net Web Pages 1.0 installers ? Since RC2 announcement I have problems finding mentioned 2 installers. Normally I would upgrade my code but this issue described above makes me stay with BETA for a while, since I have no time for migration and testing everything now.

  • How can I display an ASP.NET MVC html part from one application in another

    - by Frank Sessions
    We have several asp.net MVC apps in the following setup SecurityApp (root application - handles forms auth for SSO and has a profile edit page) Application1 (virtual directory) Application2 (virtual directory) Application3 (virtual directory) so that domain.com points to SecurityApp and domain.com/Application1 etc point to their associated virtual directories. All of our Single Sign On (SSO) is working properly using forms authentication. Based on the users permissions when logging in a menu that lists their available applications and a logout link will be generated and saved in the cache - this menu displays fine whenever the user is in the SecurityApp (editing their profile) but we cannot figure out how to get the Applications in the virtual directories to display the same application menu. We have tried: 1) Using JSONP to do an request that will return the html for the menu. The ajax call returns the HTML with the html; however, because User.IsAuthenticated is false the menu comes back empty. 2) We created a user control and include it along with the dll's for the SecurityApp project and this works; however, we dont want to have to include all the dlls for the SecurityApp project in every application that we create (along with all the app settings in the web.config) We would like this to be as simple as possible to implement so that anyone creating a new app can add the menu to their application in as few steps as possible... Any ideas? To Clarify - we are using ASP.NET MVC 1.0 since these apps are in production and we do not have the okay to go to ASP.NET MVC 2.0 (unfortunately)

  • Button Onclick event (which is in codbehind) doesn't get triggered in MVC 2

    - by rksprst
    I had an MVC 1.0 web application that was in VS 2008; I just upgraded the project to VS 2010 which automatically upgraded MVC to 2.0. I have a bunch of viewpages have codebehind files that were manually added. The project worked fine before the upgrade, but now the onclick even't don't get triggered. I.e. I have an asp:button with an onclick event that points to a method in the codebehind. When you click the button, the onclick event doesn't get triggered. In fact, when you look at the Page variable, IsPostBack is false. This is really bizarre and I'm wondering if anyone know what happened and how to fix it. I'm thinking it has something to do with the changes in MVC 2.0; but I'm not sure. Any help is really appreciated, I've been trying to figure this out for a while. (deleting the codebehinds and moving that to the controller is not really an option since there is so many pages, moving back to vs 2008 is a last resort as I want to make use of some of the VS 2010 features like performance testing.)

  • Creating vCard action result

    - by DigiMortal
    I added support for vCards to one of my ASP.NET MVC applications. I worked vCard support out as very simple and intelligent solution that fits perfectly to ASP.NET MVC applications. In this posting I will show you how to send vCards out as response to ASP.NET MVC request. We need three things: some vCard class, vCard action result, controller method to test vCard action result. Everything is very simple, let’s get hands on. vCard class As first thing we need vCard class. Last year I introduced vCard class that supports also images. Let’s take this class because it is easy to use and some dirty work is already done for us. NB! Take a look at ASP.NET example in the blog posting referred above. We need it later when we close the topic. Now think about how useful blogging and information sharing with others can be. With this class available at public I saved pretty much time now. :) vCardResult As we have vCard it is now time to write action result that we can use in our controllers. Here’s the code. public class vCardResult : ActionResult {     private vCard _card;       protected vCardResult() { }       public vCardResult(vCard card)     {         _card = card;     }       public override void ExecuteResult(ControllerContext context)     {         var response = context.HttpContext.Response;         response.ContentType = "text/vcard";         response.AddHeader("Content-Disposition", "attachment; fileName=" + _card.FirstName + " " + _card.LastName + ".vcf");           var cardString = _card.ToString();         var inputEncoding = Encoding.Default;         var outputEncoding = Encoding.GetEncoding("windows-1257");         var cardBytes = inputEncoding.GetBytes(cardString);           var outputBytes = Encoding.Convert(inputEncoding,                                 outputEncoding, cardBytes);           response.OutputStream.Write(outputBytes, 0, outputBytes.Length);     } } And we are done. Some notes: vCard is sent to browser as downloadable file (user can save or open it with Outlook or any other e-mail client that supports vCards), File name is made of first and last name of contact. Encoding is important because Outlook may not understand vCards otherwise (don’t know if this problem is solved in Outlook 2010). Using vCardResult in controller Now let’s tale a look at simple controller method that accepts person ID and returns vCardResult. public class ContactsController : Controller {       // ... other controller methods ...       public vCardResult vCard(int id)     {         var person = _partyRepository.GetPersonById(id);         var card = new vCard                 {                     FirstName=person.FirstName,                     LastName = person.LastName,                     StreetAddress = person.StreetAddress,                     City = person.City,                     CountryName = person.Country.Name,                       Mobile = person.Mobile,                     Phone = person.Phone,                     Email = person.Email,                 };           return new vCardResult(card);     } } Now you can run Visual Studio and check out how your vCard is moving from your web application to your e-mail client. Conclusion We took old code that worked well with ASP.NET Forms and we divided it into action result and controller method that uses vCard as bridge between our controller and action result. All functionality is located where it should be and we did nothing complex. We wrote only couple of lines of very easy code to achieve our goal. Do you understand now why I love ASP.NET MVC? :)

  • What version of the .NET framework ahould I target?

    - by MiffTheFox
    I'm a desktop C# developer (that is not ASP) and am wondering about version targeting for small personal projects. These are, of course, trying to reach as wide an audience as possible, and so I've been targeting .NET 3.0 (which is the latest version on a Windows Vista system without any service packs) and 2.0 (which is simply the most compatible version compatible with VS2008). Unfortunately, this precludes me from learning any technologies such as LINQ introduced post 3.0, and, with an upcoming switch to VS2010, I'm wondering if I should target the new 4.0 platform at the expense of uses without the latest and greatest, or should I just stick to trying to reach as wide a userbase as possible?

  • Cannot get net 4.5rc to work

    - by ThomasD
    I have installed .net 4.5rc from http://msdn.microsoft.com/en-us/netframework/hh854779.aspx because I would like to use the new spatial features when developing with visual visual web developer 2010 express. But when I want to change the target framework to .net 4.5 in the project properties it is not there. I have checked the directory in C:\Windows\Microsoft.NET\Framework64 and can see that there is no v4.5 folder but the v4.0 directory has been updated with a timestamp corresponding to when I installed v4.5. The version of the v4.0 directory is v4.0.30319. I am running windows 7 on my computer. Any ideas why I cannot find v4.5 ? thanks Thomas *UPDATE Based on the comment below I have found out that I am running 4.5. For others reading this post, .net 4.5 replaces the files in the .net 4.0 directory but without renaming the directory to .net 4.5 (a bit confusing). To check whether your assemblies have been updated check the product version of eg. system.dll (right click - details). According to this post http://www.west-wind.com/weblog/posts/2012/Mar/13/NET-45-is-an-inplace-replacement-for-NET-40 if the product version is above 17000 it is running 4.5.

  • Getting 404 error on MVC web-site

    - by RB
    I have an IIS7.5 web-site, on Windows Server 2008, with an ASP.NET MVC2 web-site deployed to it. The website was built in Visual Studio 2008, targeting .NET 3.5, and IIS 5.1 has been successfully configured to run it as well, for local testing. We've installed the world's simplest MVC application (the one which is created when you create a new MVC2 project in Visual Studio), and we are getting 404s on any page we try and access - e.g. <my_server>/Home/About will generate a 404. I've asked this question on StackOverflow as well, but that was before I knew it was a server issue. I have checked the following things: There are 404 entries in the IIS log, corresponding to each request. The application pool for the web-site is set to use the Integrated pipeline. The "customErrors" mode is set to off. .NET 3.5 SP1 is installed ASP.NET MVC 2 is installed I've used MVC Diagnostics to confirm all MVC DLLs are being found. ASP.NET is enabled in IIS, which we've demonstrated by running the MVC Diagnostics page. KB 2023146 did highlight that HTTP Redirection was off, so we've turned it on, but no joy. Any ideas will be greatly appreciated! Someone did suggest that there might be problems running it caused by Windows Server 2008 being 64-bit - does anyone know anything about this?

  • Facebook IFrame Application issues for certain users

    - by Kon
    We have a strange issue with running an Facebook IFrame application (using MVC 2). When I run my app and log into Facebook, I get to the application just fine. But when my coworker does it, she gets the following error: API Error Code: 100 API Error Description: Invalid parameter Error Message: Requires valid next URL. Typically this error is resolved by updating the "New Data Permissions" setting of the Facebook application. However, in this case it doesn't help. We've also tried logging in with our accounts from different computers and it seems that neither computer nor which one the MVC ASP.NET app is running from matters. The only difference is who is logged into Facebook. We've looked at our Facebook account settings, but couldn't find any obvious differences. We both have Developer access to the FB application and we both can edit its settings. However, only one of us can actually run the application without getting the above mentioned error message. Any idea what could be happening here?

  • Full Circle

    - by capgpilk
    Things have been a little bit hectic these past 6 months hence the lack of posts. My excuse is a good one though, my wife gave birth to our first son Tom back in September and it has been one hell of a rollercoaster ride since then. Things have settled back down now thank hevens.My last development gig didn't quite work out so now I have took the plunge and started contracting. It turns out my first contract is with the NHS trust that I started my development career with, which seems a bit wierd as that was 10 years ago. A lot has changed in the techniques and tools the NHS now use to develop with, there is a lot more .net with a slant towards the web side of the spectrum (at least in this NHS trust). They are really getting to grips with the MVC platform, so you will hopefully see some MVC posts coming up. The really suprising thing is that the Intranet I developed back in 2001 (classic asp migrated to .net 1.0) is still up and running and will finally be fazed out these coming weeks (to Sharepoint). It is like seeing an old friend all grown up.

  • Does MVC apply only to web

    - by Deeptechtons
    It is almost and instantaneous whenever I talk to developers about Model View Controller (MVC) they say you make a request to a url the server builds a entity (MODEL) and provides you with visual representation of that model. So does this mean MVC is only for the web or have I been meeting people who are just developers who employ MVC for writing web applications? Are there usages for MVC on desktop style applications? I for one am new to paradigm and would like to know of any super-set to MVC

  • MVC Authorize Attribute + HttpUnauthorizedResult + FormsAuthentication

    - by Anthony
    After browsing the MVC section on CodePlex I noticed that the [Authorize] attribute in MVC returns a HttpUnauthorizedResult() when authorization fails (codeplex AuthorizeAttribute class). In the source of HttpUnauthorizedResult() from CodePlex is the code (I'm not allowed to enter another URL as my rep isn't high enough, but replace the numbers on the URL above with 22929#266476): // 401 is the HTTP status code for unauthorized access - setting this // will cause the active authentication module to execute its default // unauthorized handler context.HttpContext.Response.StatusCode = 401; In particular, the comment describes the authentication module's default unauthorized handler. I can't seem to find any information on this default unauthorized handler. In particular, I'm not using FormsAuthentication and when authorization fails I get an ugly IIS 401 error page. Does anyone know about this default unauthorized handler, and in particular how FormsAuthentication hooks itself in to override it? I'm writing a really simple app for my football team who confirm or deny whether they can play a particular match. If I enable FormsAuthentication in the web.config the redirect works, but I'm not using FormsAuthentication and I'd like to know if there's a workaround.

  • Using LLBL as Model in MVC

    - by Quentin J S
    I have settled on trying to use ASP.NET MVC but the first part I want to replace is the Model. I am using LLBL Pro for the model. I have a table called "Groups" that is a simple look up table. I want to take thhe results of the table and populate a list in MVC. Something that should be very simple... or so I thought.... I've tried all kinds of things as I was getting errors like: The model item passed into the dictionary is of type 'System.Collections.Generic.List1[glossary.EntityClasses.GroupEntity]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable1[glossary.CollectionClasses.GroupCollection]'. private GroupCollection gc = new GroupCollection(); public ActionResult Index() { gc.GetMulti(null); return View( gc.?????? ); } This is all I am trying to do, I've tried lots of variations, but my goal is simply to take the data and display it.

  • Controller Index methods with different signatures

    I am trying to get my URLs in files/id format. I am guessing I should have two Index methods in my controller, one with a parameter and one with not. But I get this error message in browser below. Anyway here is my controller methods: public ActionResult Index() { return Content("Index "); } // // GET: /Files/5 public ActionResult Index(int id) { File file = fileRepository.GetFile(id); if (file == null) return Content("Not Found"); return Content(file.FileID.ToString()); } Error: Server Error in '/' Application.
