• Adding AllowPartiallyTrustedCallersAttribute To Paypal ASP.NET SDK

  - by snwr

  Currently, I cannot use Paypal Pro on my host (GoDaddy) because it requires Full trust level. After digging in Google, it seems a workaround is possible by adding AllowPartiallyTrustedCallersAttribute to the Paypal assembly. I have seen code samples that use AllowPartiallyTrustedCallersAttribute in their AssemblyInfo.cs file, however, I've yet to run into a code example that also happens to be using PayPal. My question is where should the AllowPartiallyTrustedCallersAttribute be added in my project if my objective is to make the PayPal assembly work? I have tried adding it to my AssemblyInfo.cs for the project that contains the entire website, but I have not been successful. At this point, any insight or shot in the dark would be greatly appreciated. Even if someone could point me in the general direction of some documentation I would be grateful. AllowPartiallyTrustedCallersAttribute Reference: http://msdn.microsoft.com/en-us/library/system.security.allowpartiallytrustedcallersattribute.aspx

• ASP.NET custom routes for simple requirements management tool

  - by Andrew

  I am implementing a very simple requirements management tool. I want the URLs to look like this: Shows home page for "Project One": http://projectmanager/Project/Project%20One Shows a list of requirements being worked on for "Project One" http://projectmanager/Project/Project%20One/Requirements Shows requirement 1 for "Project One" http://projectmanager/Project/Project%20One/Requirement/1 How could I set up routes so that http://projectmanager/Project/Project%20One is handled by the project controller http://projectmanager/Project/Project%20One/Requirements and http://projectmanager/Project/Project%20One/Requirements/1 is handled by the requirements controller. Is it even possible?

• Setting objects (not users) inactive after period of time in asp.net mvc

  - by bastijn

  This question is mainly to verify my current idea. I have a series of objects which I want to be active for a specified amount of time. For instance objects like ads which are shown in the ad space only for the amount of time bought, objects in search results which should only pop up when active, and frontpage posts which should be set to inactive after a prespecified time. My current idea is to just give those type of objects a StartDate and EndDate and filter the search routines to only show results which fall in the range StartDate < currentDate < EndDate. Is this the normal structure or should there be some sort of auto-routine which routinely checks for objects which are "over-time" and set a property "inactive" to true or something. Seems like this approach is such a hassle since I need a checker which runs say, every 5 minutes, to scan all DB objects. Seems like a bad idea to me. So is the first structure the most commonly used or are there any other options? When searching on google or SO the search queries only return results setting users inactive.

• DateTime from Javascript post to Controller in ASP.NET results in null (01/01/0001)

  - by Geoffrey

  This is driving me crazy, similar to this. If I use a standard form and no javascript the controller correctly binds the datetime. However when I'm posting from a form it always binds as null: "MyObject.Name": "Test name", "MyObject.Date": "5/1/2001" I've tried a couple of variations, 5-1-2001, etc. but cannot seem to get it to take. I can confirm that it is being passed to the server as it shows up in the Request.Form string. My culture is Gregorian and I've set: Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture; In Application_BeginRequest(). What gives?

• ASP.NET MVC Return to Previous Page

  - by Jason Enochs

  I have a basic Edit method in my controller that redirects back to a top level listing (“Index”) when the edit succeeds. Standard setup after scaffolding. I am trying to change this Edit method to redirect back to the previous page (not Index). Since my Edit method is not using the default mapped input parameter “id”, I am using that to pass the previous URL. In my Edit “get” method, I use this line to grab the previous URL and it works fine: ViewBag.ReturnUrl = Request.UrlReferrer.AbsoluteUri; I send this return URL to the Edit “post” method by using my form tag like this: @using (Html.BeginForm(new { id = ViewBag.ReturnUrl })) Now this is where the wheels fall off. I can't seem to get the URL parsed from the id parameter properly. UPDATE**** Using Gary's example as a guide, I changing my parameter name from "id" to "returnUrl" and used a hidden field to pass my parameter. Lesson: Only use the id parameter how it was intended to be used...keep it simple. It works now... Here is my updated code. // // GET: /Question/Edit/5 public ActionResult Edit(int id) { Question question = db.Questions.Find(id); ViewBag.DomainId = new SelectList(db.Domains, "DomainId", "Name", question.DomainId); ViewBag.Answers = db.Questions .AsEnumerable() .Select(d => new SelectListItem { Text = d.Text, Value = d.QuestionId.ToString(), Selected = question.QuestionId == d.QuestionId }); ViewBag.returnUrl = Request.UrlReferrer; ViewBag.ExamId = db.Domains.Find(question.DomainId).ExamId; ViewBag.IndexByQuestion = string.Format("IndexByQuestion/{0}", question.QuestionId); return View(question); } // // POST: /Question/Edit/5 [HttpPost] public ActionResult Edit(Question question, string returnUrl) { int ExamId = db.Domains.Find(question.DomainId).ExamId; if (ModelState.IsValid) { db.Entry(question).State = EntityState.Modified; db.SaveChanges(); //return RedirectToAction("Index"); return Redirect(returnUrl); } ViewBag.DomainId = new SelectList(db.Domains, "DomainId", "Name", question.DomainId); return View(question); } and I changed my form tag to this: @using (Html.BeginForm()) { <input type="hidden" name="returnUrl" value="@ViewBag.returnUrl" /> Thanks Gary

• Relationship Modelling in Core Data

  - by Stevie

  Hi there, I'm fairly new to Objective C and Core Data and have a problem designing a case where players team up one-on-one and have multiple matches that end up with a specific result. With MySQL, I would have a Player table (player primary key, name) and a match table (player A foreign key, player B foreign key, result). Now how do I do this with Core Data? I can easily tie a player entity to a match entity using a relationship. But how do I model the inverse direction for the second player ref. in the match entity? Player Name: Attribute Match: Relationship Match Match Result: Attribute PlayerA: Relationship to Player (<- Inverse to Player.Match) PlayerB: Relationship to Player (<- Inverse to ????) Would be great if someone could give me an idea on this! Thanks, Stevie.

• Force lowercase property names from Json() in ASP.NET MVC

  - by kouPhax

  Given the following class, public class Result { public bool Success { get; set; } public string Message { get; set; } } I am returning one of these in a Controller action like so, return Json(new Result() { Success = true, Message = "test"}) However my client side framework expects these properties to be lowercase success and message. Without actually having to have lowercase property names is that a way to acheive this thought the normal Json function call?

• Storing links to internal content pages in ASP.NET MVC

  - by mare

  I'm using a route like this routes.MapRoute( "PageBySlug", RouteType.Regular, "{slug}", new {controller = "Page", action = "Display", slug = "Default"}, null ); to map request to ~/Some-Page-Slug to ~/Page/Display/Some-Page-Slug. When adding content, user can choose to link to existing pages to create references and I then store those links in this format in the datastore: "/Some-Page-Slug". When I run the app in Cassini and pull the link out from datastore and attach it to A tag it looks like this http://localhost:93229/Some-Page-Slug and this link works. But when running the application in virtual directory under some website in IIS, the attached link generates this URL http://localhost/Some-Page-Slug, when it should be http://localhost/virtualdir/Some-Page-Slug. Of course, this generates 404 error. How can I solve this to be universally useful and working under all circumstances? Should I store it differently in the database or should I transform it into correct form in my Views at runtime and how to do that?

• Add Core Data Index to certain Attributes via migration

  - by steipete

  For performance reasons, i want to set the Indexed Attribute to some of my entities. I created a new core data model version to perform the changes. Core Data detects the changes and migrates my model to the new version, however, NO INDEXES ARE GENERATED. If I recreate the database from scratch, the indexes are there. I checked with SQLite Browser both on the iPhone and on the Simulator. The problem only occurs if a database in the prior format is already there. Is there a way to manually add the indexes? Write some sql for that? Or am I missing something? I did already some more critical migrations, no problems there. But those missing indexes are bugging me. Thanks for helping!

• How to structure controller to sort multiple criteria asp.net mvc

  - by Solomon

  Hi, What's the best way to set up a controller to sort by many (possibly null) criteria? Say for example, I was building a site that sold cars. My CarController has a function Index() which returns an IList of cars to the view, and details on each car are rendered with a partial view. What's the best way to structure this? Especially if there are a lot of criteria: Car Type (aka SUV), Car Brand, Car Model, Car Year, Car Price, Car Color, bool IsNew, or if I want to sort by closest to me etc... I'm using NHibernate as my ORM. Should I have just a ton of possible NHibernate queries and figure out which one to choose based on if/then's in the controller? Or is there a simpler way. Thanks so much for the help.

• Generate links for routes with non-parameter url segments on ASP.NET MVC 2

  - by spapaseit

  I have a route defined with several hardcoded (non-parameter) segments: routes.MapRoute(null, "suggestion/list/by/{tag}", new { controller = "Suggestion", action = "List", tag = UrlParameter.Optional }); Suppose I'm in the Index view of SuggestionController, which has a Suggestion object for Model, how can I create a link that matches that route? I'd rather use one of the provided helpers and keep the route name as null in order to avoid hard-coding to much on my views, but I can't figure out how to user these non-parameter segments in Html.ActionLink or RouteLink methods. I've even tried to render the link using plain ol' html <a href="/suggestion/list/by/<%=Model.Tag %>"><%=Model.Tag %></a> but this somehow didn't match the route either. There's probably a very simple solution and I might be over-complicating things in mi mind, but I'm at a loss. Any ideas? Thanks in advance.

• ASP.NET MVC: Triggering an action before posting to Paypal payment gateway

  - by ajbeaven

  I'm in the middle of developing an e-commerce site that is using Paypal as it's payment gateway. All I want to do is run some code before the user heads off to Paypal to pay for their order, but I have no idea how to do it. The user should click a submit button, changes are made (in this case, the status of the order), and then the user is redirected to the payment gateway. Eg: [AcceptVerbs(HttpVerbs.Post)] public ActionResult GoToPaypal(FormCollection collection) { //change order status //send user to paypal where they pay for their order } So my question is how do you do application stuff and then redirect to paypal's payment gateway? Example HTML and C# would be lovely :)

• ASP.NET MVC Populating a DropDownList with a value from the view

  - by lomaxx

  In my controller I have this: ViewData["maskList"] = new SelectList(equipmentRepository.GetMasks(), "Id", "DisplayName"); and then I bind it to my view using <div each="var nfa in mfa.NasalFittingAssessment"> ${Html.DropDownList("NasalMaskTypeId", ViewData["maskList"] as IEnumerable<System.Web.Mvc.SelectListItem>, new { class = "ddl" })} </div> Note that I'm using the spark view engine so this DropDownList is getting rendered to the page via a loop. This means that the selected value of the dropdown list will change on each iteration of the loop. What I can't work out is how to pass in the value I want to set the DropDownList to based on the value that is currently being rendered to the screen.

• Help choose a code generation tools for ASP.NET

  - by Kintaro

  Hello, I am new to the code generation tools and I would like to know how does a tool like LLBGen Pro compares with the Entity Framework? On top of that my boos is really looking into a tool called CodeOnTime http://codeontime.com/default.aspx because he likes their good UI support. I am asking here because I really want an unbiased opinion. I am not sure if LLBGen can also generate the UI. So far all the development in the house we do it the classic way coding each layer manually. However we are in need of a fast prototyping tool. Any advice to help me choose wisely will be much appreciated thanks in advance.

• Updating a DLL in a Production ASP.NET Web Site bin folder

  - by Josh Stodola

  I want to update a class library (a single DLL file) in a production web application. This web app is pre-compiled (published). I read an answer on StackOverflow (sorry, can't seem to find it anymore because the Search function does not work very well), that led me to believe that I could just paste the new DLL in the bin folder and it would be picked up without problems (this would cause the WP to recycle, which is fine with me because we do not use InProc session state). However, when I tried this, my site blows up and gives a FileLoadException saying that the assembly manifest definition does not match the assembly reference. What in the world is this?! Updating the DLL in Visual Studio and re-deploying the entire site works just fine, but it is a huge pain in the rear. What is the point of having a separate DLL if you have to re-deploy the entire site to implement any changes? Here's the question: How can I update a DLL on a production web site without breaking the app and without re-deploying all of the files?

• Alternative to COM blind aggregation in .NET for class with private interface

  - by Philip

  When extending a COM class in unmanaged C++ where the original class has private interfaces, one way to do this is through the concept of blind aggregation. The idea is that any interface not explicitly implemented on the outer aggregating class is 'blindly' forwarded to the inner aggregated class. Now .NET as far as I can figure out does not support COM aggregation natively. A somewhat tedious workaround is to create a .NET class where you implement all the required COM interfaces directly on the .NET class and simply forward to an instance of the actual COM class for any methods you don't want to override. The problem I have is when the original COM object has one or more private interfaces, i.e. undocumented interfaces that are nonetheless used by some consumers of the original class. Using blind aggregation in unmanaged C++ this is a non-issue as the calls to the private interfaces are automatically forwarded to the original class, however I can't find any way of doing the same thing in .NET. Are there any other ways of accomplishing this with .NET?

• Switching AM/PM in ASP.NET AJAX MaskedEdit localization

  - by Greg

  The sample page for the MaskedEdit says "Tip: Type 'A' or 'P' to switch AM/PM". Are these keys hardcoded? Does the control automatically change itself for cultures that use 12-hour designators that don't start with A or P? Or is just broken for those? example: Arabic (Saudi Arabia) - AM: ? Arabic (Saudi Arabia) - PM: ? Chinese (Taiwan) - AM: ?? Chinese (Taiwan) - PM: ?? Greek (Greece) - AM: pµ Greek (Greece) - PM: µµ Korean (Korea) - AM: ?? Korean (Korea) - PM: ?? Albanian (Albania) - AM: PD Albanian (Albania) - PM: MD Persian (Iran) - AM: ?.? Persian (Iran) - PM: ?.? Vietnamese (Vietnam) - AM: SA Vietnamese (Vietnam) - PM: CH Afrikaans (South Africa) - PM: nm Punjabi (India) - AM: ????? Punjabi (India) - PM: ??? Syriac (Syria) - AM: ?.? Syriac (Syria) - PM: ?.? If this control doesn't handle this situation, does anyone know of a control that does?

• Setting the ASP.NET version via MSBUILD

  - by dovholuk

  I am trying to create a new website on a remote server via msbuild (I like to call it "msdeploy"). I've downloaded and used the SDC tasks, the MSBuildExtension tasks and the MSBuildCommunity tasks but I simply can't get it right. I figure that WebDirectorySetting (from MSBuild.Community.Tasks.IIS) is my best bet but I can't find the right SettingName to pass. I'd like to use some sort of MSBuild task to accomplish this but maybe it just doesn't exist. Custom VBS or WMI are my last resort... Thanks
