Hi,
End point (HttpPost) calls a different web request by URL from the call.
It uses HttpWebRequest.GetRequestStream(...). Sometimes URL of HttpWebRequest is not available and it terminates by HttpWebRequest time out (100 sec by default) and HTTP queue can be filled up.
How can I fix it?

Assuming you're using a relatively recent version of WebAPI, make the handler async and use the HttpClient class[^] instead of HttpWebRequest.
By using async and await, you won't be blocking the request thread waiting for a response from the remote server. It will be free to return to the pool and service more requests.

Thank you for your answer.
I tried to use PostAsJsonAsync of httpClient. The same story. On localhost: ASP:NET-Request Current=3, CurrentQueueSize=4 (MAX = 10). I don't know how can I handle a bad URL ...
And ... PostAsJsonAsync doesn't exit at all.
|
|
|
|
|
To get the PostAsJsonAsync method, you'll need to add a reference to the System.Net.Http.Formatting NuGet package[^].
And if you haven't got the method, I don't see how you could have tested it yet.

I can call the method ( response = await httpClient.PostAsJsonAsync(ud.Url, byteData) ) but it doesn't return any data, just hangs.
I'm using my API like a proxy.

Well, if the URL isn't valid, it's still going to take just as long to time out.
The difference is, you're not blocking a thread from the request queue while you're waiting. Using an async endpoint, you should be able to keep serving other requests without the queue filling up.

You are right. But I can see that I can't call more than 10 requests (for limited queue = 10). I don't know why but IIS can start just 3 requests at one time (with the func). (Please note that URL is not valid. I don't know how I can handle it)

Are you running this on your local workstation?
If I recall correctly, IIS Express and the full IIS version that ships with "client" versions of Windows are deliberately limited to a maximum of 10 concurrent requests. When you deploy to a proper server version of Windows, that limit should go away.

I have a webgrid that I need to export the data to excel, that part I done in code:
@{
Layout = null;
Response.AddHeader("Content-disposition", "attachment; filename=report.xls");
Response.ContentType = "application/octet-stream";
}
Question is how do I format the columns so that:
1. I click on a row and only that row is exported to an ms excel spreadsheet,
2. The first four columns are read-only, next three is where user input data,
3. And the gridline are displayed.
How do I do or is there website example or tutorial?

You're not "exporting to Excel". You're sending HTML content, but telling the browser to open it in Excel.
Excel will do its best to import the HTML, but you'll have virtually no control over the formatting and layout.
If you want precise formatting control, you need to export a real Excel file. There are several libraries which will let you do this - for example:
NB: Don't be tempted to try Office Interop. Apart from the fact that you'd need to install and license Office on the server, it's not supported:
Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

I have to start with a new project which is asp.net web application. I have great experience working on this kind of apps, but for PC users only on company level and company network.
Now I have to make the web application to be accessed from everywhere, especially from Mobile Browsers on Android and iOS like Chrome and Safari.
In my experience I know that an aspx can't be opened through browsers on mobile devices.
So I need help on how to overcome this obstacle. Should I include something in the project or push it to open in HTML somehow.
It's a very complex project with a lot of data accessed directly from Amazon AWS ans SQL Server Database so this makes it difficult to keep the functionality trough ordinary HTML.
Please help me with this. What should I do and what should I get?
P.S. I am not asking about paying solutions or if it has to be...maybe a cheaper one 
Thanks to all of you in advance.

Hi all,
I am getting the following errors when I am trying to create a small AngualJS 2.0 application, errors are as follows

I am searching in the google, there is no much help, any help would be very greatly helpful
Thanks,

I haven't worked with AngualJS 2.0 at all but the error message seems to indicate that it cannot find your include file, Manager.ttinclude. If it is on your desktop then it may not have permission to get to it since the website is probably not running with an account that would have access to your desktop.
I suggest moving code into a folder, perhaps c:\code and setting proper permissions on it.

I don't know the reason but when I closed the VS and opened it back this error has gone, but other errors still showing up though. I wish all script-configuration related errors could go like this .
Any idea for these errors buddy? these are the only errors remaining right now
The OutputLogFile parameter is not supported by the VsTsc task. Verify the parameter exists on the task, and it is a settable public instance property
The VsTsc task could not be initialized with its input parameters
But when I am running the application its giving me the following error:
Build:Unknown compiler option listemittedfiles. BSCSecurityAddressBookWeb C:\Users\aaleem01\Desktop\Angular2Apps\BSCSecurityAddressBookWeb\BSCSecurityAddressBookWeb\tsc
Thanks,

I wrote my own identity attribute for MVC, but it has 1 flaw in it.
So when I create links to the users account, if they haven't logged in, the attribute catches it and redirects them to login.
In the attribute, I change the filter context to RedirectToRouteResult and send them to Login.
But after they login, they return to the original page and not the page I sent them to in the first place.
I guess I'm looking for a way to capture the original destination and pass it to the Login Page, so the controller can move them on their way to the proper destination.
I've seen Amazon do it in a query string. Any thoughts?
So this is a OnActionExecuting call
filterContext.Result = new RedirectToRouteResult(
new RouteValueDictionary{
{ "controller", "Account" },
{ "action", "SignIn" }
});
If it ain't broke don't fix it

I googled around and didn't find anything on the subject.
Then while I was thinking about creating the route, I thought that there must already be a route that can be captured every time the attribute fires. The destination I was sending them to in the first place.
Thus ...
string rUrl = "/" + (string)filterContext.RouteData.Values["controller"] + "/" + (string)filterContext.RouteData.Values["action"];
Then while experimenting with creating the new route, I just added another key value pair.
So on OnActionExecuting()
filterContext.Result = new RedirectToRouteResult(
new RouteValueDictionary{
{ "controller", "Account" },
{ "action", "SignIn" },
{ "rUrl", rUrl }
});
My SignIn program already had the mechanics to handle the rUrl query string so that was not a problem.
This is really cool at the moment unless it backfire on me later down the road.
I think this is going to bite me back if I send the user to simply login and return to the same page.
I need to figure out how to read a query string, perhaps that would be in the route values as well.
[Edit]
I like this version now. For some reason this puts a big smile on my face!
The ability to write these attributes in MVC is amazing. Saves so much work in the long run.
string rUrl = filterContext.HttpContext.Request.QueryString["rUrl"] != null ? (string)filterContext.HttpContext.Request.QueryString["rUrl"] : null;
string goUrl = "/" + (string)filterContext.RouteData.Values["controller"] + "/" + (string)filterContext.RouteData.Values["action"];
filterContext.Result = new RedirectToRouteResult(
new RouteValueDictionary{
{ "controller", "Account" },
{ "action", "SignIn" },
{ "rUrl", rUrl != null ? rUrl : goUrl }
});
If it ain't broke don't fix it

Excel interop (or any Office interop) is not supported on asp.net. Look at the XML SDK or the Excel ODBC driver.

I know that there are many answers on google, I tried many but nothing worked! I have a CodeMirror text editor and a list of files.I want to display the contents of a file when click on it.This is my first time using Javasctipt so I can't figure out what's wrong with my code.
This is the code I wrote so far:
controller:
public ActionResult Index()
{
StudentsCodes model = new StudentsCodes();
model.Student = (Student)CurrentUser;
var user = UserManager.FindById(((Student)CurrentUser).InstructorID);
model.Instructor =(Instructor) user;
return View(model);
}
public PartialViewResult DevelopmentPartial (StudentsCodes path )
{
return PartialView(path);
}
Main view:
<script type="text/javascript" src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
<script type="text/javascript" src="~/Scripts/jquery-3.1.1.js"></script>
<ul id="tree">
@foreach (var file in Directory.GetFiles(Server.MapPath("~/Content/" + Model.Student.UserName + "/CompilerProject/" + name)))
{
var filename = Path.GetFileName(file);
<li id="filelist" onclick="@(Model.path = "~/Content/" + Model.Student.UserName + "/CompilerProject/src/" + @filename)">
@filename
/li>
}
<div id="partial">
@{
Html.RenderPartial("DevelopmentPartial",null);
}
</div>
<script>
$(document).ready(function () {
$("#filelist").click(function (e) {
@{Html.RenderAction("DevelopmentPartial", Model);
}
});
});
</script>
PartialView:
@using (Html.BeginForm())
{
var fileContents= "";
if (Model==null)
{
fileContents = "";
}
else
{
fileContents = System.IO.File.ReadAllText(Server.MapPath(Model.path));
}
@Html.TextArea("code", fileContents, new { id = "code" })
}
The result was a non-clickable list elements , 3 text editors overlap each other, and display only the contents of the last file in the list. What am I doing wrong?
