ADO.NET :: Open Project And Model.Designer.cs Has So Many Errors
Mar 7, 2011
The first time I created my model, I thought a manual fix would keep it okay. But everytime I open my project, the model is updated and the Designer.cs is formatted weird. The following picture shows the main problem: I'm just not sure how to permanently fix it other than going through and deleting the "System.Data." and "System.whatever" paths when they are referenced. That is the only way the build/publish succeeds, and it's very time consuming to complete each time.
My current Web Site does not have any designer.cs files. (Yes it is not a Web Application)The site is complete but now I added 2 Clases to my site and all good but when I want to make use of my GridView it tells me this:This is because I wrapped my code with the same namespace as in my classes like so....
namespace samrasWebPortalSQL { public partial class GridView : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Functions.RemoveCaching(this); [code]...
I was using VS2008 everything ws going well but one day because of some problem i have to reload the windows and VS2008 and since then i am unable to open the designer.It does not give me any error message but i am unable to use any of the feature after clicking design or view designer from solution explorer.I have tried reinstalling the VS2008 but it does not solve my problem.
when I try to open the view designer in my windows application project I get an error msg - there is no editor available for 'C:documents and setting....Form1.vb' Make sure the application for the file type (.vb) is installed.
If I pass in true to the ValidationSummary() helper so that it only displays model-level errors, how can I get the summary to display custom errors I add to ModelState?For instance, here is what I am after. I want my data annotation errors to display next to the textbox's using the ValidationMessage helper, but in my business layer I may throw an exception that I want to display in the validation summary.
We're migrating from the web site to the web application model. Is there a way to allow the designer to use ftp to upload a single aspx page (foo.aspx and foo.aspx.cs) without requiring the use of the VS2008 Publish feature? We're a small shop and haven't bothered using source control as it wasn't much of an issue with the web site model. If the designer uses the Publish feature my binaries will be overwritten. I know that static pages are compiled at run time so I thought this would be possible but my tests result in errors. I've clicked around for some guidance but come up empty handed.
i am using VS 2005 with Sql Server 2005 Business Inteligance Studio. All my reports are by default open in Xml editor, not in Report Desginer. how to change it to Report Desginer , i don't find any open with option .
I'm wondering what the best practice is in reporting back to the browser about application or model state errors that would be displayed to the user. Can you throw an exception and handle it in the error handler of the jquery post? For example, consider this method:
[HandlerErrorWithAjaxFilter, HttpPost] public ActionResult RetrievePassword(string email) { User user = _userRepository.GetByEmail(email); if (user == null) throw new ClientException("The email you entered does not exist in our system. Please enter the email address you used to sign up."); string randomString = SecurityHelper.GenerateRandomString(); user.Password = SecurityHelper.GetMD5Bytes(randomString); _userRepository.Save(); EmailHelper.SendPasswordByEmail(randomString); if (Request.IsAjaxRequest()) return Json(new JsonAuth { Success = true, Message = "Your password was reset successfully. We've emailed you your new password.", ReturnUrl = "/Home/" }); else return View(); }
Is it correct to throw an exception in this case when the user is null? Or should I instead do this and handle it in the success handler of the jquery post: return Json(new JsonAuth { Success = false, Message = "The email you entered does not exist in our system. Please enter the email address you used to sign up.", ReturnUrl = "/Home/" });
Curious what the best practice is for returning errors to a view from a controller where the error isn't really a validation error, but more like "user not found" or "service timeout" type of errors. (in ASP.NET MVC2 framework)
I've been adding them to the ModelState's model errors, but that doesn't seem appropriate. (although easy to implement and maintain)
Example - A user tries to log in, and their credentials do not match a known user.
I just started my first MVC 2 project in VS 2010. I decided to start the debugger, just to see the default controllers in action, and have received several of the following kinds of errors for the test unit project:
Error 1 The type or namespace name 'Controllers' does not exist in the namespace 'MajorProductions' (are you missing an assembly reference?) c:userskevindocumentsvisual studio 2010ProjectsMajorProductionsMajorProductions.TestsControllersHomeControllerTest.cs 8 24 MajorProductions.Tests
From what I can see, however, MajorProductions.Controllers does exist, as it's created by default in my regular/non-test project.The unit test code in question is:
[Code]....
And the error is being triggered by the using MajorProductions.Controllers line. I have similar errors elsewhere in my unit test project, so I figure if I can fix this, I can fix the others.
I created a small mvc site using framwork 4.0. I found my hosting company uses 3.5. I changed my project and compiled and there were no errors. Now when I run, I get this error on all pages: How can I get it to work in .net 3.5?

How do you delete more than one entity at the same time in the designer Entities list. it seems that the designer interface only allows the selection of 1 entity at a time....
For the first time in my career, I'm working on an ASP.Net (v3.5) project that has been set up as a Visual Studio 2008/10 Web Site Project.
I'm not keen on this way of working this way for various reasons but for the moment and until such time as the company sees the virtue in working in an environment with namespaces, designer and project files etc., I have to continue with the existing codebase.
I've run into some odd issues since I began this but perhaps the oddest one of all is that althought VS lets me build the code, it doesn't reliably pick up compilation errors so these are not noticed until runtime.
I know the website model allows dynamic/hot compilation when a request is made for a specific but I can't see why it wouldn't do this when I manually (F5) build/rebuild the project. Its immensely annoying as you can imagine and I can't find a workaround.
I have decided to go back to an old project that I had placed on hold, to get familiar with MVC 3 Razor. It is a Jokes website (some of you already know). I have been watching these video tutorials on Code First Entity Framework 4, and I have managed to build my model in a project of its own. Then I went and created another project (this time MVC 3 Razor Blank Project) and linked the two togther. I am trying to simply list the joke, but I get the error saying:
CS0012: The type 'System.Data.Objects.DataClasses.EntityObject' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. public class _Page_Views_Home_Index_cshtml : System.Web.Mvc.WebViewPage<IEnumerable<LNModel.Joke>> {
Here is the code in my HomeController:
[Code]....
I know what the error means, I am missing a { using System.Data.Entity; } statement somewhere. But I can't understand why ! according to the video, if I have referenced my projects to that statement, I shouldn't be having this problem !
I am trying to find a way to have my Entity Framework model in a seperate project within my ASP.NET solution.
Currently I have my DataManager project (which contains my EF model and some classes) and a second project which contains all my web project files.
The problem that I have come across is that I have a database connection string in a App.Config file in my DataManager project and the same connection string in my Web.Config from my web project. I basically have a duplicate connection string.
Is there a way to only use only one connection string in my project (preferably from my web.config)?
My only concern is that when it comes to compiling my project I will not be able to change the connection string in the App.Config contained in my DataManager project.
i am loading a page when we click a button .i am require a loadimage.show when i div laoding time and disapper when i div loaded but model form content is not show
on my desktop computer, i first installed VS 2005.. after few weeks i installed VS 2008.. i created a project on VS 2008..on my laptop, i installed VS 2008..i transferred the project from my desktop to my laptop but i can't open it.. one of my clasm8s said told me that even if i created it on VS 2008 on my desktop, it still uses framework 3.0 because VS 2005 was the first installed.. is he correct? what should i do?
I wasn't sure which subforum to post this in as it appears to be a complex widespread issue. I have a WebApplication that was mostly coded in VB but had two C# classes and everything was working fine and it was created in VisualStudio 2005 as a Website. I finally finished converting the existing WebApplication as it was to C# and everything compiled fine. Trying to organize and such I created new Classes, DAL and BLL and migrated the existing classes into the appropriate location. Still compiled fine. Here's where the problems started.
Wanting to move from a Website to a Project, I created a new project WebApplication and migrated all the files from the Website into the Project. I re-added the references to the classes and .Net components and updated all the project settings to mirror what was in place before. Now when I try to compile. BAM. 171 Errors, mostly "The name '' does not exist in the current context." It appears most of them are in regard to Profile or accessing page components (Labels, Textboxes, etc) I can provide more detail about specific errors if needed but I was hoping maybe I just didn't do something incorrectly when moving to a Project from a website.
here's what i did. on my desktop computer, i first installed VS 2005.. after few weeks i installed VS 2008.. i created a project on VS 2008. on my laptop, i installed VS 2008. i transferred the project from my desktop to my laptop but i can't open it.. one of my clasm8s said told me that even if i created it on VS 2008 on my desktop, it still uses framework 3.0 because VS 2005 was the first installed.. is he correct? what should i do?
