  • Mixing .NET 3.5 with 4/4.5 assemblies in the same process

    - by lysergic-acid
    Our team builds a .NET 3.5 WinForms based application that we'd like to migrate to the latest .NET version (4.5). Our application uses many "external" components (can be thought of as plugins) that are also currently .NET 3.5 based. I'd like to know what runtime/core libraries are used in case we convert ONLY THE APPLICATION to compile using .NET 4.5? Should this scenario properly work? (loading .NET 3.5 assemblies in a 4.5 process)? * The plugin assemblies are loaded via reflection. How does the CLR runtime handle such a scenario? is this a safe practice?

  • Checking for nulls in ASP.NET MVC Controllers

    - by Brian McCord
    Another opinion question: What is the proper (in your opinion) to check for nulls in an MVC controller. For instance, if you have an edit controller that fetches a record from the db based on an id, what do you do if that record is not found? I found this article, but I'm not sure I like that method. Do you just check for it with an if statement and redirect to a 404 page? What solution do you use?

  • Asp.net control inside of fancybox modal is not "working"

    - by studiothat
    Your typical "It doesn't work" freak out going on over here. Any direction would help. I have a login control on my master page and I'm trying to only display it using jquery fancybox and then redirect the user once they are logged in. But any buttons or controls that should do "something" when pressed when I put inside the fancy box are not responding. If I keep the div visible and then use the control not using fancybox I get the expected result. What are my options?

  • get and set for class in model - MVC 2 asp.net

    - by bergin
    Hi there, I want to improve the program so it has a proper constructor but also works with the models environment of MVC. I currently have: public void recordDocument(int order_id, string filename, string physical_path, string slug, int bytes) { ArchiveDocument doc = new ArchiveDocument(); doc.order_id = order_id; doc.filename = filename; doc.physical_path = physical_path; doc.slug = slug; doc.bytes = bytes; db.ArchiveDocuments.InsertOnSubmit(doc); } This obviously should be a constructor and should change to the leaner: public void recordDocument(ArchiveDocument doc) { db.ArchiveDocuments.InsertOnSubmit(doc); } with a get & set somewhere else - not sure of the syntax - do I create a partial class? so: creating in the somewhere repository - ArchiveDocument doc = new ArchiveDocument(order_id, idTaggedFilename, physical_path, slug, bytes); and then: namespace ordering.Models { public partial class ArchiveDocument { int order_id, string filename, string physical_path, string slug, int bytes; public archiveDocument(int order_id, string filename, string physical_path, string slug, int bytes){ this.order_id = order_id; etc } } How should I alter the code?

  • Querystring formatting in asp.net MVC 2

    - by Stuart
    Seems like a straitforward question but I can't quite figure it out myself... I have an actionlink like so Html.ActionLink( "Test", "test", new { q = "search+twitter" } ) This produces a url string as follows http://myserver/test?q=search%2Btwitter But i would like to preserve the plus sign (which i assume is being UrlPathEncoded) so that I get the following url http://myserver/test?q=search+twitter Is there an easy way to do this whilst still using Html.ActionLink ?

  • ASP.NET Compiles on page load, but not on Ctrl+Shift+B

    - by Steve Syfuhs
    during debug in cassini the code runs fine, but when I explictly build it, the compile breaks on an object saying it can't find the reference. During a breakpoint shows the proper reference to the object, and I can view the debug intellisense. The code itself is simple using CFTW.Controls; ... controls_LatestPresentations c = LoadControl("~/controls/LatestPresentations.ascx") as controls_LatestPresentations; c.loadContent(); return RenderControl(c); The control is a simple user control, with the namespace CFTW.Controls. The calling code is in a webcontrol, which lives in the same folder. I even tried adding the calling code to the same namespace.

  • ASP.NET MVC 2 - Custom route doesn't find controller action

    - by mcfroob
    For some reason my application isn't routing to my controller method correctly. I have a routelink like this in my webpage - <%= Html.RouteLink("View", "Blog", new { id=(item.BlogId), slug=(item.Slug) }) %> In global.asax.cs I have the following routes - routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "MoreBlogs", "Blog/Page/{page}", new { controller = "Blog", action = "Index" } ); routes.MapRoute( "Blog", "Blog/View/{id}/{slug}", new { controller = "Blog", action = "View"} ); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Blog", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); And then I have a class BlogController that has a method - public ActionResult View(int id, string slug) { ... etc. } I put a breakpoint in the first line of the View method but it's not getting hit at all. I checked with a route debugger for the format localhost/Blog/View/1/test and it matched my custom route. All I'm getting is a 404 while running this, I can't work out why the route won't post to the view method in my controller - any ideas?

  • Generating jquery 'rules' from business model to UI in asp.net mvc

    - by jim
    Hi all, I've had a good look around and am certain that there's no matching question on SO, so here goes. Has anyone created a 'helper' method on their model that generates jquery (or plain javascript) rules validation dynamically, based on the criteria/rules that are contained within the object and taken from a repository (i.e. DB). What i'm thinking of is a discrete set of partial views (and associated models) that have rules at the business logic 'level' and rather than (or in combination with) validating the rule(s) at postback, translating the same rules into tightly focussed jquery methods that work identically at client (js) and server (c#) levels. I can see benefits here re performance. Also, the rules definitions could be created in a single place (in c#) and the jquery generated off of that, thus allowing single edits to update both code streams. I appreciate that there would be limitations imposed by language specific contstraints but the general principle could be quite interesting if used appropriately. I'm also aware that testibility could be an issue when using two different language structures and hoping to achieve similar test outcomes - but those aside... any thoughts or experiences of similar out there?? cheers jimi

  • ASP.Net mysterious behaviour

    - by kalan
    Does anyone have any idea why this works (expression in the if-clause) if (!(childNode.Roles != null && !Helper.HasEqualElements((string[])childNode.Roles, System.Web.Security.Roles.GetRolesForUser()))) AddNode(childNode, parentNode); And this doesn't if (childNode.Roles == null || Helper.HasEqualElements((string[])childNode.Roles, System.Web.Security.Roles.GetRolesForUser())) AddNode(childNode, parentNode); The problem is that the second if-clause sometimes doesn't work. Though it always works in debug mode, but it sometimes fails while running. And the strange thing is that these two pieces of code seems absolutely equal for me.

I am obviously missing something basic, any help?

  • ASP.MVC 2 Model Data Persistance

    - by toccig
    I'm and MVC1 programmer, new to the MVC2. The data will not persist to the database in an edit scenario. Create works fine. Controller: // // POST: /Attendee/Edit/5 [Authorize(Roles = "Admin")] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Attendee attendee) { if (ModelState.IsValid) { UpdateModel(attendee, "Attendee"); repository.Save(); return RedirectToAction("Details", attendee); } else { return View(attendee); } } Model: [MetadataType(typeof(Attendee_Validation))] public partial class Attendee { } public class Attendee_Validation { [HiddenInput(DisplayValue = false)] public int attendee_id { get; set; } [HiddenInput(DisplayValue = false)] public int attendee_pin { get; set; } [Required(ErrorMessage = "* required")] [StringLength(50, ErrorMessage = "* Must be under 50 characters")] public string attendee_fname { get; set; } [StringLength(50, ErrorMessage = "* Must be under 50 characters")] public string attendee_mname { get; set; } } I tried to add [Bind(Exclude="attendee_id")] above the Class declaration, but then the value of the attendee_id attribute is set to '0'. View (Strongly-Typed): <% using (Html.BeginForm()) {%> ... <%=Html.Hidden("attendee_id", Model.attendee_id) %> ... <%=Html.SubmitButton("btnSubmit", "Save") %> <% } %> Basically, the repository.Save(); function seems to do nothing. I imagine it has something to do with a primary key constraint violation. But I'm not getting any errors from SQL Server. The application appears to runs fine, but the data is never persisted to the Database.
