This was done:$("#ref-show").click(function (e) { e.preventDefault(); $.ajax({ url: "Test.aspx/GetTable", type: "POST", contentType: "application/json; charset=utf-8", dataType: "json", success: function (data) { $("#ref-content").html(data.d); } }); return false; _From the server, I return the line: [WebMethod] public static string GetTable() { Table result = new Table(); // Формирую html таблицу result = Provider.CreateHtmlDataTable(); StringWriter sw = new StringWriter(); result.RenderControl(new HtmlTextWriter(sw)); return sw.ToString(); } Maybe someone needs it.

If you use MVM. Let's just say we add a class library. In it, we will keep the Model and ViewModels. And all other projects will contain View.ASP.Net should work, too. ♪ ♪

Take a data collection to transform into a model, right? If that's the case, I've faced a problem like this, and I haven't broken my head for one hour, and it's like,<div class="row row-counter"> <input hidden type="text" name="adreses[@i].id" value="@adreses[i].id"> <div class="col-sm-5"> <input type="text" name="adreses[@i].key" class="form-control" value="@adreses[i].key" placeholder="Салон"> </div> <div class="col-sm-5"> <input type="text" name="adreses[@i].value" class="form-control" value="@adreses[i].value" placeholder="Салон"> </div> <div class="col-sm-2"> <div class="btn btn-danger col-sm-12 row-del">X</div> </div> </div> It's a clipping from the idea that a collection for a successful change in View should be like,__[grunting]Index]Field"Directly for your example: model♪Orders[grunting]i]UserName♪ where model - is the name of the parameter taken in the shape processing device:[HttpPost] public ActionResult EditAutosalon(IndexViewModel model)

Try it like that, you wrote it to me, but the point should be understood.var users = db.Users.Select(s=> new {Id=s.id, Name= s.FirstName + " " + s.Patronymic}).ToList(); model.Users = new SelectList(users, "ID", "Name");

<form action="form.php" method="post"> <input type="radio" name="summa" value="100">100 <br/> <input type="radio" name="summa" value="200">200 <br/> <input type="radio" name="summa" value="400">400 <br/> <br/> <input class="button" type="submit" value="Отправить" /> </form>

Get the assembly on the project. Microsoft.mshtml.dllvar wb = new WebBrowser(); // ... var doc = wb.Document as mshtml.IHTMLDocument2; doc.execCommand("Print", true, 0); and if have to be called from javascript on the web page,document.execCommand('print', false);

Element authentication It can only be used in an application level configuration file, it cannot be used on a virtual path.If it's basically two different websites, why did you put them in one project? Do two separate projects and deploy them to the required addresses.To be clearer than that. I'm putting my local IIS in pictures below. There. goodsMark-stats - it's just a file. trash - it's a virtual catalogue. A Sc.Web - it's a web application.So that's the element. authentication I've been working for Patient and Co-worker to be web applications. This can't be done in a special way to lay down the files - it can only be done by IIS.PS is the simplest way to create a web application if all the files are in place:

The problem is, when you published the IIS application, it works on behalf of the user under which the app is launched.You can solve this problem in several ways: Bad route: to launch an application pool on behalf of a user who has rights to establish a database.Good road: Install a record with the necessary privileges in the database, remove Integrated Security=True from the connection and add the User Id (name of the user created) and Password (parole of the user created).In this case, the connection line shall be approximately such: <connectionStrings> <add name="StudentsContext" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename='|DataDirectory|\Students.mdf';User Id=username;Password=userpassword;" providerName="System.Data.SqlClient" /> </connectionStrings>

that js is a purely client language that is not true, it is a language of general use of ECMAScript, and it also works (JavaScript, JScript and ActionScript) and node js uses v8. If you're writing tests, you're looking towards selenium the most powerful thing. If you write the passer and you need the results of AJAX, you'll have the code , the good is that all the browsers are built for the FF and you'll need the pages of the AJAX processors separately.

Maybe you should write that.Dim a() as integer = {1,2,3}

I think you just don't have a SMTP server or he doesn't answer.How do you have the properties of SmtpMail.Host and SmtpMail.Port... you have to check them through the phone?

According to the code, every challenge to the method will work with a unique file. So you don't have shared resources here.Therefore, there is no need for security.If it is necessary to synchronize access to common files, it may be: https://ru.stackoverflow.com/q/1243324/373567

On the question of complexity, the listed should not be compared with one parameter.You know, you know, it's a thing that treats one class of technology and that makes it easy to compare.To figure this out, we have to go back to the past.ASP was first. It was a "slightly subdirected php-cheek from Microsoft," where the html and code were blended, but there was already a strict typology and the possibility of connecting COM-components.This has opened up a great deal of opportunities to post the websites with active content of technology server-side, because the JS was at this point very well conceived only to draw snowflies on the front page between December and March.Then, as the ASP abrreviat has already been known to the audience (and Microsoft is very fond of the three-block abreviations) ASP appeared. NETThis was a huge step forward that allowed NET Framework to be applied on the Web server. The "possibility" here means the possibilities of languages (C#, VB.NET, and it seems F# - and they're all in an intermediate byte-code, which was done with NET runtime. But since the NET Framework (versions 1, 2, 3, 3.5, 4, 4.5, 4.51, 4.52, 4.6, 4.7 and 4.8) was only under the vindu, it was nailed to IIS and Microsoft Server, which, of course, caused ironic laughter in all bearded linux-admins.At the same time, ASP.NET MVC emerged, which identified the application of the Model-View-Sontroller template in ASP.NET. In fact, instead of a randomly grouped code, it was suggested that the code should be divided into essentially Model, View or Controller.NET Core was born in order to become a paid-up. Who works the same way on both vinda and the linux. It's a huge freymvork, of scale comparable to Spring' from the Java world. Its part relevant to WEB is named ASP.NET Core. It had the possibility of using the MVC template, which was likely to imply ASP.NET Core MVC.Because it's boring to write a lot of abstracts, names have narrowed down, for example, from ASP.NET Core MVC to NET Core MVC and, in fact, who's in the middle.In fact, there are:♪ NET Core is the whole frimevork.ASP. NET Core is part of the fraimvor buried under WEB.ASP. NET Core MVC is part of the foam box stored under WEB, using the MVC templateTherefore, in returning to the question, the comparison should be based on such a scheme:There is ASP or ASP in the name of technology. NET? If so, then this technology has something to do with WEB. If it's just "ASP" - it's likely NET's just forgotten to sign 'cause ASP technology is very old and it's no longer in use.Is there a Core in the name of technology? If so, the technology is cross-splatform and is based on the foil of NET Core. If there is a Framework in the name of technology or simply no Core word - it is likely that there is a NET Framefork that only operates WindowsIs there a MVC in the name of technology? If yes, the model-View-Controller division template is applied, if not, to the extent that it is not. Or cut down some of the abbreviations, considering everyone's gonna figure it out.So the answer to you. current The question (and prior to the questioning, you mentioned the use of the MVC template) as follows:| Название технологии | WEB или общего назначения? | Кроссплатформенная? | | | | | | ASP.NET Core | WEB | да | | | | | | .NET Core | общего назначения | да | | | | | | ASP.NET? | WEB | нет, только Windows | Is that clearer?

It's overwhelmed.public async Task<BaseNewsContentItem[]> GetContentItemRMMultipleAsync(IEnumerable<int> itemIds, UserKey user, bool needGetInfoByChat = true) { var items = await _feedDataService.GetItemsWithDependenciesAsync(itemIds, user); if (items == null || !items.Any()) return null; var tasks = new List&lt;Task&lt;BaseNewsContentItem&gt;&gt;(); foreach(var item in items) { tasks.Add(ToContentItemAsync(item, user?.ToUserIdVM(), needGetInfoByChat)); } return await Task.WhenAll(tasks); } Accepted IEnumerable There's a point, for universality, but to return, no, so I'll get the mass back. And where there are lots, you better work with the masses, don't pack in. IEnumerablethe compiler will reward you for this more streamlined code.And there's a way to kill a car of nature.private Task<BaseNewsContentItem> ToContentItemAsync(BaseItem item, UserIdVM user, bool needGetInfoByChat = true) { if (item == null) return Task.FromResult<BaseNewsContentItem>(null); if (item.CommunityId.HasValue) return GetContentItem(item, user, needGetInfoByChat); if (item.RegionGuid.HasValue) return GetContentItemByRegionGuid(item, user, needGetInfoByChat); return GetContentItemFromChats(item, user, needGetInfoByChat); } You can rewrite like that.private Task<BaseNewsContentItem> ToContentItemAsync(BaseItem item, UserIdVM user, bool needGetInfoByChat = true) => item switch { null => Task.FromResult<BaseNewsContentItem>(null), _ when item.CommunityId.HasValue => GetContentItem(item, user, needGetInfoByChat), _ when item.RegionGuid.HasValue => GetContentItemByRegionGuid(item, user, needGetInfoByChat), _ => GetContentItemFromChats(item, user, needGetInfoByChat) }; But who likes it as much.

Under Windows, use the IIS hosting: https://docs.microsoft.com/ru-ru/aspnet/core/host-and-deploy/iis/?view=aspnetcore-3.1 Under Linux, you can sit under Kestel: https://docs.microsoft.com/ru-ru/aspnet/core/fundamentals/servers/kestrel?view=aspnetcore-3.1 It's just that, using RID linux-x64, threw it in linux, created a demon that's gonna be launched and everything is ready! (Don't forget to dotnet runtime)Well, the best way is to docker a container under some apache, nginx or HAProxy: https://docs.microsoft.com/ru-ru/aspnet/core/host-and-deploy/linux-nginx?view=aspnetcore-3.1

Judging by the mistake, you don't have CORS for the Api server Web. What you wrote in the counteraller:HttpContext.Current.Response.AppendHeader("Access-Control-Allow-Origin", "*"); must make Middleware before the request is processed. CORS in ASP.NET Web Api is implemented and accessible from under the bonnet.To include CORS, you need to set up nuget-packet. Microsoft.AspNet.WebApi.Cors and method WebApiConfig.Register add EnableCors♪ There are two different ways of adding CORS:Add CORS for all api-Controllers;Add CORS for the right controller/method.Mode No. 1Only one change required WebApiConfig.Register:public static class WebApiConfig { public static void Register(HttpConfiguration config) { var cors = new EnableCorsAttribute("*", "*", "*") { SupportsCredentials = true // По дефолту, false. Если cross-origin запрос должен отправлять еще и данные для аутентификации (например, Cookie), то нужно выставить это поле в true }; config.EnableCors(cors); config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{action}/{id}", defaults: new { id = RouteParameter.Optional } ); } } In fact, this method adds to each api-Controller and api-method CORS policy. [EnableCors(origins: "", headers: "", methods: "*", SupportsCredentials = true)])Mode No. 2♪ WebApiConfig.Register:public static class WebApiConfig { public static void Register(HttpConfiguration config) { config.EnableCors(); config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{action}/{id}", defaults: new { id = RouteParameter.Optional } ); } } And... FileApiController.cspublic class FileApiController : ApiController { [HttpPost] [EnableCors(origins: "", headers: "", methods: "*", SupportsCredentials = true)] [Route("api/FileApi/uploadData")] public void UploadData([FromBody] AccrualPayment [] accrualPayment) { //... } } Details EnableCors Can be read in Microsoft: https://docs.microsoft.com/en-us/aspnet/web-api/overview/security/enabling-cross-origin-requests-in-web-api

Changed the language of Visual Studio 2019, from Russian to English, and now it's working great, browser opens.

Yeah, use the sss, like that. center > a{ display: none; } If you give me a link or a code that's on the way out, I'll be able to say exactly what and where to write. I think the point is understandable.
