  • LINQ to SQL for tables across databases. Or View?

    - by BritishDeveloper
    I have a Message table and a User table. Both are in separate databases. There is a userID in the Message table that is used to join to the User table to find things like userName. How can I create this in LINQ to SQL? I can't seem to do a cross database join. Should I create a View in the database and use that instead? Will that work? What will happen to CRUD against it? E.g. if I delete a message - surely it won't delete the user? I'd imagine it would throw an error. What to do? I can't move the tables into the same database!

  • How can I ajax load new pages/views into MainContent when using a master page

    - by antevirus
    Hello. Instead of using Html.ActionLink to load subpages into MainContent, I would like to load them with ajax. For example (taken from Site.Master): <%= Ajax.ActionLink("HOME", "Index", "Home", new AjaxOptions() { UpdateTargetId = "main" })% <%= Ajax.ActionLink("ABOUT ME", "Index", "About", new AjaxOptions() { UpdateTargetId = "main" })% <%= Ajax.ActionLink("VIEW MY WORK", "Index", "Work", new AjaxOptions() { UpdateTargetId = "main" })% <%= Ajax.ActionLink("SERVICES", "Index", "Services", new AjaxOptions() { UpdateTargetId = "main" })% <%= Ajax.ActionLink("CONTACT", "Index", "Contact", new AjaxOptions() { UpdateTargetId = "main" })% This works, but when i click one of the links it seems to load the master page all over again. http://emma.jabit.se Click a link and see what happens. Any ideas how to solve this?

  • Membership systems for MVC4 that support RavenDB

    - by brad oyler
    I create a lot of quick "proof of concept" MVC apps and I actually found the SimpleMembership provider that shipped with the MVC4 templates to be very handy since it gets me up and running with user registration & OAuth in a matter of minutes. But...I've started to use RavenDb (on RavenHQ for a lot for my projects). So, I starting trying to implement my own "custom membership provider" based on the ExtendedMembershipProvider and while doing that I realized that didn't make much sense. I later stumbled upon 2 interesting projects that try to solve this exact problem: WorldDomination.Web.Auth: https://github.com/PureKrome/WorldDomination.Web.Authentication MemFlex: https://github.com/OdeToCode/Memflex Both are pretty interesting recent efforts and was wondering if these are the only ones being built right now. I'm essentially looking for nuget pkg that I can drop into a MVC4 app, connect to my RavenDb and be done. I'm willing to build this thing but don't want to duplicate any efforts that are already in motion. Thx!

  • I cannot make log4net work in my web application :(

    - by vtortola
    Hi, I'm trying to set up log4net but I cannot make it work. I've put this in my Web.config: <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="logfile.log" /> <appendToFile value="true" /> <rollingStyle value="Composite" /> <maxSizeRollBackups value="14" /> <maximumFileSize value="15000KB" /> <datePattern value="yyyyMMdd" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" /> </layout> </appender> <root> <level value="DEBUG" /> <appender-ref ref="RollingFileAppender" /> <appender-ref ref="TraceAppender" /> </root> (StackOverflow is not rendering correctly the code I've pasted, I don't know why) Then, in my code I execute: log4net.Config.XmlConfigurator.Configure(new FileInfo(HttpContext.Current.Server.MapPath("~/Web.config"))); ILog log = LogManager.GetLogger("MainLogger"); if(log.IsDebugEnabled) log.Debug("lalala"); But nothing happen. I check the "log" variable, and contains an LogImpl object, that has all the logging levels enabled. I get no error or configuration warning, I cannot see any file in the root, in the bin or anywhere. What do I have to do to make it work? Cheers.

  • HTML input not working correctly with AJAX update panels used else where on page

    - by Sean P
    I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout. Here is my code: <div id="divFileInputs" runat="server"> <input id="file1" name="fileInput" type="file" runat="server" size="50" style="width: 50em" onfocus="AddFileInput()" class="textbox" /></div> <select id="selectFileList" name="ListBox1" size="5" style="width: 50em; text-align: left;" class="textbox" /> <input id="RemoveAttachmentButton" type="button" value="Remove" onclick="RemoveFileInput()" class="removebutton " /> </div> Here is my code behind: Protected Sub CopyAttachments(ByVal issueId As String) Dim files As HttpFileCollection = Request.Files Dim myStream As System.IO.Stream Dim service As New SubmitService.Service For i As Integer = 0 To files.Count - 1 Dim postedFile As HttpPostedFile = files(i) Dim fileNameWithoutPath As String = System.IO.Path.GetFileName(postedFile.FileName) If fileNameWithoutPath.Length > 0 And issueId.Length > 0 Then Dim fileLength As Integer = postedFile.ContentLength Dim fileContents(fileLength) As Byte ' Read the file into the byte array. Send it to the web service. myStream = postedFile.InputStream myStream.Read(fileContents, 0, fileLength) service.ClearQuestAttachToIssue(issueId, fileNameWithoutPath, fileContents) End If Next service = Nothing End Sub When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded. Anyone know how to fix this?

  • implementing security with session variables, how it is insecure

    - by haansi
    I am doing web based projects in dotnet. Currently I am implementing security using session variables. I keep current user id and user type in session and authenticate user from these session variables (say Session["UserId"],Session["UserName"] and Session["UserType"]). Please help me understand how this could be insecure. I've heard that such security can be broken and applications can be hacked very easily, like it is possible to get session id and directly connect to that session id etc. Please guide me on this.

  • How to use StructureMap to inject repository classes to the controller?

    - by Lorenzo
    In the current application I am working on I have a custom ControllerFactory class that create a controller and automatically sets the Elmah ErrorHandler. public class BaseControllerFactory : DefaultControllerFactory { public override IController CreateController( RequestContext requestContext, string controllerName ) { var controller = base.CreateController( requestContext, controllerName ); var c = controller as Controller; if ( c != null ) { c.ActionInvoker = new ErrorHandlingActionInvoker( new HandleErrorWithElmahAttribute() ); } return controller; } protected override IController GetControllerInstance( RequestContext requestContext, Type controllerType ) { try { if ( ( requestContext == null ) || ( controllerType == null ) ) return base.GetControllerInstance( requestContext, controllerType ); return (Controller)ObjectFactory.GetInstance( controllerType ); } catch ( StructureMapException ) { System.Diagnostics.Debug.WriteLine( ObjectFactory.WhatDoIHave() ); throw new Exception( ObjectFactory.WhatDoIHave() ); } } } I would like to use StructureMap to inject some code in my controllers. For example I would like to automatically inject repository classes in them. I have already created my repository classes and also I have added a constructor to the controller that receive the repository class public FirmController( IContactRepository contactRepository ) { _contactRepository = contactRepository; } I have then registered the type within StructureMap ObjectFactory.Initialize( x => { x.For<IContactRepository>().Use<MyContactRepository>(); }); How should I change the code in the CreateController method to have the IContactRepository concrete class injected in the FirmController? EDIT: I have changed the BaseControllerFactory to use Structuremap. But I get an exception on the line return (Controller)ObjectFactory.GetInstance( controllerType ); Any hint?

  • How to handle null {id} on route?

    - by MattSlay
    What if a user hits my site with http://www.mysite.com/Quote/Edit rather than http://www.mysite.com/Quote/Edit/1000 In other words, they do not specify a value for {id}. If they do not, I want to display a nice "Not Found" page, since they did not give an ID. I currentl handle this by accepting a nullable int as the parameter in the Controller Action and it works fine. However, I'm curious if there a more standard MVC framework way of handling this, rather than the code I presently use (see below). Is a smoother way to handle this, or is this pretty mush the right way to do it? [HttpGet] public ActionResult Edit(int? id) { if (id == null) return View("QuoteNotFound"); int quoteId = (int)id; var viewModel = new QuoteViewModel(this.UserId); viewModel.LoadQuote(quoteId); if (viewModel.QuoteNo > 0) { return View("Create", viewModel.Quote.Entity); } else return View("QuoteNotFound"); }

  • Using DisplayFor inside a display template

    - by Oenotria
    I've created a htmlhelper extension to reduce the amount of repetitive markup when creating forms: public static MvcHtmlString RenderField<TModel, TValue>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TValue>> expression) { return htmlHelper.DisplayFor(expression, "formfield"); } The idea being that inside my views I can just write @Html.RenderField(x=>x.MyFieldName) and it will print the label and the field's content with the appropriate div tags in place already. Inside the displaytemplates folder I have created formfield.cshtml containing the following: <div class="display-group"> <div class="display-label"> @Html.LabelFor(x => x) </div> <div class="display-field"> @Html.DisplayFor(x => x) </div> </div> Unfortunately it doesn't appear that it is possible to nest DisplayFor inside a display template (it doesn't render anything). I don't want to just using @Model because then I won't get checkboxes for boolean values, calendar controls for dates etc. Is there a good way around this?

  • What are the different methods for injecting cross-cutting concerns?

    - by Stacy Vicknair
    What are the different methods for injecting cross-cutting concerns into a class so that I can minimize the coupling of the classes involved while keeping the code testable (TDD or otherwise)? For example, consider if I have a class that requires both logging functionality and centralized exception management. Should I use DIP and inject both required concerns via an interface into the class that requires them? Should I use a service locater that I pass to each class that will require some cross cutting functionality? Is there a different solution altogether? Am I asking the wrong question entirely?

  • Using Public/Private keys in reverse

    - by Wizzarding
    Hi, I have a situation where I need to make some data available for reading by anyone from a specific device, where the data is pre-loaded on the device, but I cannot allow anyone to create their own device and populate it with their own data in the same format. I know this sounds a little crazy, but there is a good reason! I was planning to use Public Key cryptography, encrypting the data with a public key, but then publishing the private key to anyone who wants to read the data. However, after looking at the RSACryptoServiceProvider and how it works it looks like I cannot just publish the private key as the private key can be used to create the public key. Could someone confirm that suspicion, or give me some hints on how I might be able to make this work! Many Thanks.

  • Redirect in Application_Error redundant if using customErrors?

    - by Ek0nomik
    If I have a customErrors section in my Web.config that says to redirect to Error.html, then putting code in the Application_Error method in the Global.asax to redirect to Error.html is redundant is it not? Technically, I could bypass the Web.config by redirecting to a different page in the Application_Error method if I wanted to, but since I don't want to go to a separate page I don't think I need the code.

The application will involve sending data to and from a database, user login, import export to csv, txt files, and print function. What security features do I need to consider for such an application. (SQL injection for starters) ?
