I'm trying to upload a file to my MVC 2.0 app, but I keep getting connection resets. I know that the file size limit can cause these, but it's currently set at 20MB in the web.config and the file I'm trying to upload is only 3MB...
I'm not sure how to diagnose this issue and I can't look into error handling on the MVC side since the request never makes it there...
I've read several questions explaining how to handle file uploads in asp.net mvc. I am trying to submit both the file as well as form fields describing it. That might be the issue. I'll go write to the code:
View code:
<% using (Html.BeginForm("CreateFile", "Video", FormMethod.Post, new { enctype = "multipart/form-data" }))
{%>
<fieldset>
<legend>Fields</legend>
<p>
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
</p>
<p>
<label for="Password">Password:</label>
<%= Html.TextBox("Password")%>
<%= Html.ValidationMessage("Password", "*")%>
</p>
<p>
<label for="Description">Description:</label>
<%= Html.TextBox("Description")%>
<%= Html.ValidationMessage("Description", "*")%>
</p>
<p>
<label for="DateUploaded">DateUploaded:</label>
<%= Html.TextBox("DateUploaded")%>
<%= Html.ValidationMessage("DateUploaded", "*")%>
</p>
<p>
<label for="DateRecorded">DateRecorded:</label>
<%= Html.TextBox("DateRecorded")%>
<%= Html.ValidationMessage("DateRecorded", "*")%>
</p>
<p>
<input type="submit" value="Submit" />
</p>
</fieldset>
<% } %>
Controller code:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult CreateFile(VideoDTO video, HttpPostedFileBase f) //[Bind(Exclude="VideoId")]
{
foreach (string file in Request.Files)
{
HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;
if (hpf.ContentLength == 0)
continue;
string savedFileName = Server.MapPath("Videos") + Path.GetFileName(hpf.FileName);
hpf.SaveAs(savedFileName);
video.FileName = hpf.FileName;
}
repository.CreateVideo(video);
return RedirectToAction("Index");
}
I've seen several examples, but haven't come across one that is trying to submit both a file and other form data. Some other things of note is other examples seem to not put a HttpVerb attribute on the action method at all and have an empty parameter string. The files I'm looking to accept will be video files of various types but they can be anywhere from 100-300 mb. The files I've attempted to use (locally) have been rather small comparatively (50 or so mb).I know it's been asked but I feel like my issue here is different somehow. When I submit the page I see:
The connection was reset
The connection to the server was reset while the page was loading.
In an asp.net web form, I keep getting a connection reset error message. The page is doing a some long running processing (about 2-5 minutes).
I have no problem when the web request comes from the same machine as the web server. But when the request originates across the network, I get a connection reset error about 1:30 or 2 minutes into waiting for a response.
I have set the in web.config for this application and put the application it's own application pool.
What else can I try?
Edit
The purpose of this page is to accept input from the user, calculate something, and send the result back to them. The long running calculation isn't something I can offload until a later time.

On an ASP.NET Web Application I have an upload file functionality. I'm restricting the file size up to 10 MB by configuring the inside web.config the maxAllowedContentLength attribute. (I'm using IIs 7.0 BTW).
It get the desired HTTP Error when I access the application from the local machine:
HTTP Error 404.13 - Not Found The request filtering module is configured to deny a request that exceeds the request content length.
When I access the application from another machine I get
The connection was reset The connection to the server was reset while the page was loading.
How can I get a more descriptive error when my application is accessed remotely?
When am Exporting Huge data From datagridview to Excel am getting this kind of Problem.

same code will work to export the small amount of data..

But on uploading file with size more than the max filesize it is showing "connection reset" error.
How should i do this.
Scenario:Own rolled jQuery Ajax post to validate an input field on unfocus Standard submit button for post on form
If I cause validation to fire and wait until I see it complete in firebug then click save all is fine. If however I leave a change in a field and then click the submit button directly (so both ajax and standard post happen at almost the same time) the request hangs in the browser before returning a 'connection reset'. If running in VS debug I see nothing unless I hit pause. I am then presented with the following callstack:
System.Web.dll!System.Web.Hosting.IIS7WorkerRequest.ReadEntityCoreSync(byte[] buffer, int offset, int size) + 0x23 bytes
System.Web.dll!System.Web.Hosting.IIS7WorkerRequest.ReadEntityBody(byte[] buffer, int size) + 0x18 bytes
System.Web.dll!System.Web.HttpRequest.GetEntireRawContent() + 0x2d4 bytes
System.Web.dll!System.Web.HttpRequest.GetMultipartContent() + 0x45 bytes
System.Web.dll!System.Web.HttpRequest.FillInFormCollection() + 0xad bytes

System.Web.dll!System.Web.HttpRequest.HasForm.get() + 0x46 bytes
System.Web.dll!System.Web.UI.Page.GetCollectionBasedOnMethod(bool dontReturnNull) + 0x62 bytes
Background:ASP.NET 4 MVC 2 Web application with some legacy webforms pages (the page involved in both the ajax post and standard post is the same webforms page) running locally on Win7/IIS7.
I could potentially disable the submit button while the ajax validation fires. However even if I do that I'm intrigued to know what has caused this seemingly time based/concurrent request problem.
I am using upload feature in my asp website. So i am using file input type. But this control add a default upload button browse and a textbox where path is shown after selecting file in Internet explorer. I don't want to show browse button etc. So what i did is add a button "Attach a File" and i have written script 'triggerFileUpload' function where i make it to click on upload control.
So now when i click on "Attach a File" button browse for file windows appears and can select file to upload. But when i click on submit button the file upload control becomes reset and file is not uploaded. Error is that on clicking to submit button the file control becomes null. It happens only in internet explorer.
Below is code which can show the problem i am facing in IE.Same problem comes if i use asp:FileUpload control also. (my plan is to hide the file control and show only attach file button to user).

I am experiencing the following page error when trying to use the FileUpload control on my web page to upload files larger than 3MB or so. The error is as follows:"Problem loading page The connection was reset The connection to the server was reset while the page was loading.
* The site could be temporarily unavailable or too busy. Try again in a few moments.
* If you are unable to load any pages, check your computer's network connection.
* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."I suspect this may be due to a timout issue. If so, how can I increase the timeout period for this control / process? I am coding in VB.NET.
my asp.net app uses dynamic stylesheets. so each of my pages uses a pre_init method to load the relevant stylesheet. the stylesheet is the same for ALL users of the app.for each page load, i don't want to query the database to determine which stylesheet to use. therefore, I simply load the stylesheet from a STATIC variable that I store when the app starts.
works fine locally. however, on the production server the STATIC variable is reset to Null after about 5 minutes. why is that?? is there a better way for me to handle this? Should I change something in IIS? Should I change the methodolgoy I am using to retreive the stylesheet?
Each .aspx page includes:

I have implemented a HttpModule in ASP.NET (framework 2.0).From my logging on the server, I can see that the http request is being picked up by my HttpModule, and my code runs successfully (writing content back to the Response stream).However, the web browser (IE, FF, Chrome, all the same) just give me a "connection reset" error message.I've checked the Event Log on the server; there are no related errors or messages there.EXTRA INFO: When I use the "Live HTTP Headers" plugin in FF, it does not even display my client request (although I am sure it reaches the server, due to the request being captured in the server log).

I have created a website (VB) on my local host. A couple of pages on this website use gridviews or detailsviews with an AccessDataSource connection to a MS Access database. This works perfectly. But now I want to move this website to a hosting provider. And on this hosting provider my website works well but not the pages with a connection to the Access database. I searched the whole internet for a solution but I didn't found it.
Folder structure on the host:
- db > Access databases (name: testdemo.mdb)
- logs
-wwwroot > website (for example, the gridview is placed on index.aspx).
I think AccessDataSource didn't work, but what kind of code may I use in the index.aspx and web.config? My hosting provider said only, use a direct link to the database and not a relative, for example: E:xxx.comdb estdemo.mdb
I have created a ASP.NET 4 application in VS 2010 using Silverlight and RIA Services.
After finishing the first release on my development pc, I'm starting some deployment testing in a server in my local network.
After sucessfully published the web application using the Visual Studio FTP publishing option, I notice two strange things:
1 - On the IIS properties of the website I have uploaded my files to, you can see now a connection string, named as LocalSqlServer that points to the aspnetdb.mdf database file. I had a look in the web.config file and I could not find this connection strind defined there. So, where is it located? Where did IIs got it from?
2 - As the aspnetdb.mdf file is not deployed withtin the web application and I a musing SQL express in my testing server, where can I drop the mdf and ldf files so they can be attached when the applicaiton runs? I know I can perform an attach operation using management studio,but I'm wandering where is the DataDirectory folder ASP.NET looks for to attach it at runtime?
i have done a project using ASP.NET and SQL database...and it's working good.but everytime i run the project in other computers i need to set connection path to database.without set connection how to run the project.using "App Path"? please let me how to set App Path in ASP.NET PROJECT.
View 2 RepliesI'm using Visual Studio 2008, and my database is SQL Server 2000.
I want to add a connection to the Server Explorer in VS. The Data source is Microsoft SQL Server (SqlClient). After entering in all my information and I click Test Connection, it is successful.
But when I click OK, I get the error:
Unable to add data connection. ExecuteScalar requires an open and available connection. The connection's current state is closed.
Seems one have to configure your connection a bit different in NHibernate configuration. In my web.config I'll have it like this (and it work):
Quote:
<add name="ApplicationServices" providerName="System.Data.SqlClient" connectionString="Data Source=72.118.116.71,1511;Initial Catalog=xxx;User Id=xxxx;Password=xxxx;" />
The sample I'm using (Trying to figure out NHibernate) configure a local database like this:
Code:
<property name="connection.connection_string">
server=.SQLExpress;database=NHibernateSample;
Integrated Security=true;
</property>
I've been trying various variations of this and cant get it to work:
Code:
<property name="connection.connection_string">
server=72.118.116.71,1511;database=xxxx;User Id=xxxx;Password=xxxxx;
Integrated Security=true;
</property>
Keep getting this errror:
The login is from an untrusted domain and cannot be used with Windows authentication."
Right now, when I am copying the website to host server, I am changing the connection string in webconfig file and at each location of a sqldatasource or a query .. thats like more than 30 places where I am doing this.
When I am done copying the website, I have to change all the connection strings back to dev server for me to keep working on the dev copy....
I have an application 'A' builded by VS2005 and Framework 2.0.50727 before.And I am fixing an application 'B' builded by VS2003 with Framework 1.0, so I installed 1.0 yesterday.Everything worked fine but today when I was running 'B', it showed "Visual Studio cannot create or open the application because the Web server on this computer is not running. Start the Web serber before proceeding."Even if I reintall 1.0, VS2003 still shows this message.Then I closed VS2003 and open VS2005 to run application 'A' to see if app 'A' works fine.
But after I run app 'A', the IE says cannot display web page.So I checked my Default Web Site in IIS, it says 'The connection to the server was lost. Do you want to attempt to reconnect?'I tried solutions from internet to solve running app 'A' :1. Type C:WINDOWSMicrosoft.NETFrameworkv2.0.50727 -i or -u in command.2. Checked the World Wide Web Publishing status is startedThe running app 'A' still gave me cannot display IE picture.Does anyone know how can I do for it?
I have decrypted my connection string in web.config file of the application programatically. But after deployment under the ASP.net tab of application virtual directory when I click edit configuration the connection strings in web.config file are visible in decrypted format i.e readable form.
View 3 RepliesI have been preparing for a conversion of an old application to an ASP.NET webapplication at beginning of the year. Generally, the development version of the webapp will also be the webapp that goes into production. We here make "clones" of the database server, assign new name, etc, which is then used for development, training, and so on without any threat of changing data on the real db (sql server 2005). I know it is possible to have more then one connection string in the web.config. My question centers around if there is a simple method for allow multiple connection strings and pick the one that is to be used for dev, production, training, and so on? I originally thought about constructing some type of admin form that the connection string can be selected from.
View 2 RepliesI have an app that is a bit old and will eventiall be rewritten but until I get the time it needs to continue to be patched. THe app is desgined broken into three layers (Web, DAL, BLL) The web site uses the DAL.DLL and BLL.DLL and the Website has some dataaccess and the sonnection string is saved in the web.config. For the DAL it is stored in the app.settings. Is there a way for the DAL to use the connection string that is stored in the Web.config even thought it is in DLL for the production site?
