Flash - Inaccurate Progress Bar When Uploading Large Files Using ASP.NET And Uploadify?

Feb 10, 2010

I've got an ASP.NET web application (utilizing WebForms) and am using Uploadify to handle uploading large files. This is done by posting the file to an HttpHandler.

Example of code (simplified for demonstration purposes):


the progress bar being displayed doesn't actually reflect the progress of the upload, and shows the upload as being complete long before the file is actually uploaded. Therefore, the user interface effectively appears like it is doing nothing while the progress bar stays at 100%, until the file is complete.

In some cases, the upload simply fails after reaching 100%, with the OnComplete event never getting fired, almost like the response from the HttpHandler is getting lost in transit, even though the file is saved.I've tried both Flajaxian and SWFUpload, and experienced similar issues with the progress bar being completely out of sync with actual upload progress, indicating completion well before the upload was actually complete.

This problem is not apparent when testing locally, or with small files (typically under a few megabytes) as these tend to upload fairly quickly and there's little or no lag between the file being uploaded and the progress bar completing.Is there any way of using a Flash upload solution (such as Uploadify) with an ASP.NET web application and have the progress bar better represent the actual progress of the upload?

Update: Eventually, I gave up trying to use a flash based uploader as they seemed a bit too awkward, especially the progress bar, which didn't represent the actual progress of the upload at all. Replaced this with Brettle NeatUpload instead which works much better.

Uploading Files Asynchronously In .NET (AsyncFileUpload And Flash Controls Not Suitable)

Jan 20, 2011

I have looked at various options for uploading files asynchronously in ASP.NET. the default Microsoft control does full postback, AsyncFileUpload control has only one button and cannot change the text and appearance and I need two buttons browse and upload. not interested in flash based controls. I found this


html close to what I need. it uses iframe to achieve this, but I would like a simplified version of this. I just want to display an image while uploading, I don't need number of bytes transferred etc. how can I achieve this? I just need to upload the file asynchronously without page flickering and save the file to the server and update the page contents after the upload is complete.

Getting Request Timed Out Error When Uploading Large Files?

Oct 6, 2010

We have page that allows the users to upload documents (multiple). When the upload takes a long time - either due to the size of the files or due to slow upload speeds - we get a exception saying "Request timed out".

We found that the exception is thrown as soon as the upload is complete. So we have modified the executionTimeout config entry to 6000 secs. But this error still shows up consistently. We are running IIS6, .net 3.5 sp1 (asp .net 2.0).

Update.I'm able to reproduce this issue with relatively small files (multiple files with total of 75MB)

Web Forms :: Upload Large Files - Stop Waiting For Uploading?

Sep 24, 2010

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. 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.

C# - How To Calculate The Optimum Chunk Size For Uploading Large Files

Sep 9, 2010

Is there such a thing as an optimum chunk size for processing large files? I have an upload service (WCF) which is used to accept file uploads ranging from several hundred megabytes.

I've experimented with 4KB, 8KB through to 1MB chunk sizes. Bigger chunk sizes is good for performance (faster processing) but it comes at the cost of memory.

So, is there way to work out the optimum chunk size at the moment of uploading files. How would one go about doing such calculations? Would it be a combination of available memory and the client, CPU and network bandwidth which determines the optimum size?

EDIT: Probably should mention that the client app will be in silverlight.

How To Capture Posted Image From Flash / Swf For Uploading

Sep 1, 2010

This is the first time I've come across this kind of problem before and I'm having trouble approaching it.

I have a swf developed by someone else that posts an image and I have to create a handler of some kind to capture it, name it, then upload it to a directory. I've tried a couple ways and nothing is working.

this is a quick an dirty approach, just an aspx file

<%@ Page Language="C#" %>
<%@ Import Namespace="Components" %>
<%@ Import Namespace="System.IO" %>
<script runat="server">
public partial class upload : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)
string uploadDirectory;
uploadDirectory = Server.MapPath(@"images/");
string imageName = "image.jpg";
string uploadPath = uploadDirectory + imageName;
//FileUpload imageUpload = new FileUpload();
// Get the data from the POST array
string Email = Request["email"];
HttpPostedFile imageFile = _context.Request.Files["image"];

this is another approach using a handler.

<%@ WebHandler Language="C#" %>
using System.IO;
using System.Web;
using System.Web.Configuration;
using System.Web.IHttpHandler;
public class Uploader : IHttpHandler.i
public void ProcessRequest( HttpContext _context )
string uploadDirectory;
uploadDirectory = Path.Combine(_context.Request.PhysicalApplicationPath, @"images");
//uploadDirectory = Server.MapPath(@"images/");
string imageName = "image.jpg";
string uploadPath = uploadDirectory + imageName;
//FileUpload imageUpload = new FileUpload();
// Get the data from the POST array
string Email = _context.Request["email"];
HttpPostedFile imageFile = _context.Request.Files["image"];
