What is better way to large upload file.using a web service or in application itself.If in application, how can we check that files is to upload in a regular interval.actually i dont want user to wait for complete uploading, when it starts uploading user will get response of uploaded and uploading will be done in backgroud.I am not sure this type of task can be done in webservice also so that user doesnot need to wait for complete uploading.and one more query which event fires when the page redirects to another page.Is it Page_UnLoad or Dispose
I am trying to upload file in WCF.When I try to upload file I am getting following error message. System.ServiceModel.CommunicationException:The socket connection was aborted.
I have a scenario which I am looking at where large files which are about 30-40 MB are being FTPed to a server. I am looking at creating a .net screen with the FTP control to upload the file to a Unix server. I need to know how much of a performance hit it is to work with such large files, is it a feasible option in this scenario? I might have to create a .net component for the same and call from ASP application. Is it doable?
I have standard asp.net file upload control on a page. If a user try to upload large file they get all the cryptic error messages like page not found etc.I dont want them to be able to upload large files, but still want to show gracefull error message saying that file is too large to upload or something like that. Is there any way to do that?
i have a large excel file which has 1 lakh row , i want to insert these data in my table i am using entity framework for insert but it takes more than 45 minutes to insert which is too much, i want to speed up the uploading process what should i do. can I use multithreading for it if yes then how i can use? if any other way to do this process.
I need large file upload support in my hosted (godaddy) medium trust asp.net app.It obviously needs to be responsive with indication of progress, so handling the stream myself is important.This all seems pretty simple and works well when in full trust:
1.Write an HttpModule that listens for file uploads.
2.Get the HttpWorkerRequest object from the Context using reflection.
3.Write out stream to a FileStream
All very well and good except that I keep getting permission exceptions when trying to get the HttpWorkerRequest object from the context in medium trust. Whether I use reflection or I use System.IServiceProvider.GetService() to get the object (which is clearly using reflection), I get the same error.
I have also tried using System.Web.HttpPostedFile. It has a property InputStream. But it seems this object is uploading the entire file on initialization, so no good.I have googled myself tired, and can't find another alternative.
Even if it is a security risk to let users have the HttpWorkerRequest object, surely the framework provides another way to handle the stream of files when Method="POST" and enctype="multipart/form-data"
My problem is Asyncfileupload control is working fine when i debug the application and upload large file...but when i run this from iis it only upload file less then 5 kb. why is that so?? i did try adding Httpruntime maxRequestLength="4096" i tried to find on search but no help... did m i mising any settings..??
This works in other browsers but not in chrome. I am trying to allow users to upload large files and have an ajax call to update them on the progress of the file upload.
So a unique ID is generated on the client side and added to the action of the form before sending. Then the form is submitted (form only contains a file upload input) and an ajax call is made to get the progress of the upload. The ajax call goes to another page and uses the ID to lookup the upload.
I am using JQuery 1.5.1. Debugging this and putting something on the error function give me nothing other than "error". Not very helpful. I used Chrome's debugger and it just says failed to load resource xxxx.aspx. xxx.aspx is the URL i needed. Turns out that there seems to be some sort of conflict between the form and the ajax call.
I am using the async file upload control to upload to a image file. I want the user to upload only jpg files. And for that I am checking the uploadedfile content type in server side, after the upload complets. I wanna check this, before upload starts. There is one javascript method
function startUpload(sender, args){}
but how to access the content type of the file selected by user.
internet Explorer cannot display the webpage when trying to upload a large image.I have a webform for inserting images. There are four FileUpload controls on the page, allowing the user to upload 4 images at the same time. It inserts them directly into database, in Image field, but before that I am resizing them to 200px x 160 px.
The problem I am having is as follows: If I try to upload larger images (over 2MB), one at the time, everything goes fine. But if I try to upload 2 or more larger images at the same time, I get the message: Internet Explorer cannot display the webpage, and there is a button below: Diagnose Connection Problems.
Can you please point me to what could be an issue? It obviously has something to do with the image size, but I have no idea what.
We use the MojoPortal to a website and have some problems to upload files that is around 100 MB with the upload module. (Pleas note that this has probably nothing to do with MojoPortal but with the ASP.NET and the IIS)
The MojoPortal is set to use regular file Upload(not Neat Uploader) and to be able to upload big files we have set the following :
The problem is that the upload will cacel after a couple of minuts (Aborted).
Is there any other values that I need to set to make this possible? The MojoPortal itself should not have any settings for this as far as I know so its regular ASP.NET 4.0.
Anyone got some good pointers at an open source (article for creating your own would even be better) component to upload large files.SlickUpload for instance works great, and surely worth the money, but as this is for a pet project, a paid solution is just not what I'm after.
I am building a website where i need a page where user can upload large video files, i have created WCF service with streaming but i am calling that WCF service from Button_Click event of web page.
I have used below mentioned article for WCF service creation
WCF Streaming
I have used streaming as it should be efficient and should not be buffered in memory of server.
Now questions
1) I am having doubts that the entire file is uploaded to the web server and then it is transferred to WCF Service server...if this is true then i am not getting advantage of streaming as well as iis and web server will be down very soon if user uploads large file or multiple user are uploading files con currently
2) Is there any other efficient way to do same operation with some other technique
EDIT :
If I am not calling WCF Service method from ASP .Net code in that case also it is transferring bytes to the web server which i have checked with HTTPFox
I have checked above thing with upload control and putting one button on UI whose click event is bound to one method in code behind.
So, still i am having that confusion that how data is transferred
Client Machine - Web Server (ASP .Net Application) - Service Server (WCF Service) Client Machine - Service Server (WCF Service)
NOTE : If i am putting a debug point on button_click and uploading 10 kb file it hits that in less then 1 sec. but if i am uploading 50 mb file then it is taking time.
I placed code of calling WCF service inside that button_click event
I need to create an upload site to upload large files over 2GB I want ot create a site like [URL]. Once these files get upload i want them to have a link to the file created but the link encrypted. I know there is a limit to http upload. I have used a bunch of the flash upload web apps but are capped at a specfic mb becuase of .net. What options are out there.
We'd like to restrict the maximum upload file size in our web site. We've already set the appropriate limits in our web.config. The problem we're encountering is if a really large file (1 GB, for example) is uploaded, the entire file is uploaded before a server-side error is generated, and the type of the error is different whether the file is huge or not. Is there a way to detect the size of a pending file upload before the actual upload takes place?
Here's my relevant web.config settings that restrict requests to 16 MB:
[Code]....
Update:
I know that client-side technologies like Flash can detect file sizes before upload, but we need a server-side workaround because we're wanting to target platforms that have no Flash/Java/ActiveX/Silverlight support. I believe that IIS or ASP.NET has a bug that's allowing large files to be uploaded despite the limits, so I've filed a bug here.
Would an ISAPI extension give me more control over request processing than HTTP modules and handlers, such as allowing me to abort an upload if the Content-Length header is seen to be larger than the allowed limit?
Update 2:
Sigh. Microsoft has closed the bug I filed as a duplicate but has provided no additional information. Hopefully they didn't just drop the ball on this.
I want to upload files to the web servers from the client machines.
Can i upload a file on a network share folder using file upload control?
I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?
Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?
I am trying to figure out a solution to upload large files under a web page. I know WCF + Streaming is a proper solution for large file transfers, but I am not sure how to get the WCF client implemented under ASP.NET. Here is the link: [URL] Besides, is there anyway I could implement a progress bar showing the upload progress while the file is being uploaded, and voiding page timeout?
I am uploading file through ftp using asp.net,c#. If my file size is small(3 MB) then it is uploading file bit if my file size is large then it is not uploading all file. it is uploading only about 3500 kb. i am using the following code.

I have a requirement by my client to be able to upload extremely large files.
I'm talking about 7 GB files. The website they are currently running on is a ASP.NET 4.0 app, so obviously the standard upload scheme for my web app is not going to work.
I'm tossing around multiple options trying to figure out what the best route to go would be.
One option I'm thinking about seeing if I can do would be to have a BitTorrent Uploader. The end users for this app will typically have the same file on hand, so the idea would be that an end user would go to the site, say that they wanted to upload a file. At that point, they would pick the file, and then the server would immediately mark that person as a seed for that file. Then, my web app would go to a preconfigured leech on our side, and instruct the leech to download the file. I would expect at some point during or after this process the torrent would do some magic to find other seeders on the client's network, or wherever, but that's the idea.
Is there any technology out there already that does this? Or am I describing something that I'm going to have to build from the ground up?
