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.

View 2 RepliesI am trying to change the text of a asp:textbox and collapse some ajaxToolkit:CollapsiblePanelExtenders within some ascx controls on my page as well as output a dynamically generated file. I have no problem collapsing the CollapsiblePanelExtenders and changing the text of the textbox from the codebehind or outputting a file. The problem arises when I want BOTH of these events to happen on the same postback. Unfortunately using Response.Write negates all of the other changes to the page.

View 4 RepliesI'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...
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.
connection to server reset after uploadting files more than 5mb.
View 3 RepliesOn 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?

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.Form.get() + 0x45 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 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.

View 1 RepliesIs it possible to choose a specific database that will be used with the entity framework? At this time, I use the connection string in the Web.Config as database authentication.
I have twelve databases, each of them has the same structure and the same stored procedure.
There is one database for each client. When a client wants to login into the system, he needs to choose his database name from a listbox.
I would like to create a dynamic connection string which will include the database name chosen by the client.
just for my testing purpose i know i can define both the connection's outside in a single web config file by different name's and access them in my front end according to it but what if i want to have seprate for both connection's web.config situation is like this see image so i want to access my connections from second web config file how i can do that.

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).

View 2 RepliesI am downloading file from database using the following code. This code downloads an excel file from the database which has a macro attached to it when it is opened. This macro reads file name of the excel file and uses it for its computation. Everthing works file if user saves the file on his harddisk and then open if but if he directly opens the file from the dialog(by hitting 'Open' button) then file name of the opened excel file comes out be the name of the webform that has the above code and this leads to error in the macro. Is there any option through which i can control the name of the file if user directly opens the file from dialog or the option to disable or remove 'Open' button form the dialog?

View 1 RepliesI 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).
