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)
I use file upload control.........and below this there is upload button which include programming to upload file.........
It is working fine for file size of less than 2mb but when i pick file of 5 mb(say) and i click on file upload button or any other button then outcome is
Internet Explorer cannot display the webpage
I placed break point on upload button but control doesn't go their..........
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. Is it Page_UnLoad or Dispose.
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):
$(".uploadify").uploadify({[CODE]....
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.
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.
i want to check my fileuploas size . if bigger then 2mbm error message will popup, this is my some of my code
If file_newimage.HasFile = True Then Dim ext As String ext = System.IO.Path.GetExtension(file_newimage.FileName).ToString If ext <> ".jpg" And ext <> ".png" And ext <> ".bmp" And ext <> ".jpeg" Then MessageUser("Photo uploaded must be in .jpg/.png/.bmp/.gif or .jpeg format") Else If file_newimage.PostedFile.ContentLength > 2097000.0 Then
[Code]....
but when i input image 12MB, just to check my coding my page went "Page cant be displayed" ...
I've checked many threads about this but I'm not sure how to fix this:When I try to upload a 33 mb file while debuggin, control directly falls into application_endrequest even when I've a breakpoint set to first line in application_beginrequest in my global.asax.cs. I can see the page in non-postback case.My maxRequestEntityAllowed is set to 400000, and in web.config I got
<httpRuntime maxRequestLength="1024000"/>
What else do I need to fix? I can upload a 25mb file btw.platform: IIS7, Windows 7 64 bit, .NET framework 2.0, integrated pipeline
have developed a Asp.net application which uploads data from Excell Sheet and then Inserts those data after doing several Checks to the Mysql data base.The Issue which Iam facing is that when Iam uplading lage amount of data at a time say around that 10000, the application crashes and gives the Unable to Open connection to server Error.The same app works well 1000-2000 data.
Is there a way of filtering large CSS files for the only required selectors on a page, and creating css files that contain just these selectors?
Case: I have a very large CSS file that I want to filter on a per page basis, so that the file size is cut down and can be cached by mobile devices. I was thinking along the lines of something like a server side dust me selectors tool.The particular project I am working on is using ASP.NET MVC.
How can we upload video to Youtube without using its api in asp.net? My requirement is that user uploads video to our site and after admin approval that video is uploaded to Youtube. I'm using ASP.NET
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.
I'm using a web form that allows users to upload media files. The code works great on small to medium size files, but I've found that if a file is really big(like bigger than 15MB), the user will get a 404 error. Currently I'm using the code below to handle the file. Does .NET provide another way to handle larger files?
I used this sample to work around the issue we were having with large files. [URL] Unfortunately, when I attempt to download large files of 30MBs or more, the download times out and the user gets a partial download. It doesn't seem to be a consistant percentage of the download either. I attempted to download a 50MB file and got to 33MB. When trying a 30MB file, I downloaded 24MB.Below is my code.
if (File.Exists(strFilePath)) { fileName = System.IO.Path.GetFileName(strFilePath); Response.Clear(); system.IO.Stream iStream = null; byte[] buffer = new Byte[10000]; int length; long dataToRead; try { iStream = new System.IO.FileStream(strFilePath, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.Read); dataToRead = iStream.Length; //FileInfo file = new FileInfo(strFilePath); Response.ContentType = "application/octet-stream"; Response.AddHeader("Content-Length", iStream.Length.ToString()); Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName.Replace(" ", string.Empty)); while (dataToRead > 0) { if (Response.IsClientConnected) { length = iStream.Read(buffer, 0, 10000);..................
I'm testing a very simple aspx page on Visual Studio's own ASP.NET Development Server(the local server). On the webpage there is a FileUpload control which can upload jpg file up to 2MB without problems. On uploading bigger files, the browser immidiately show "The web page cannot be displayed". It does not show any exception which really puzzles me. "The web page cannot be displayed" is normally caused by network problem, but in this case it's a local server and it can handle smaller jpg file fine. Whta's the problem here?
We have a problem with some people working from home where when uploading 30-40mb (max upload is 50mb) they are timing out. Naturally when these people are on site they have no problems because of the network speed with have. What are peoples thoughts about extening the time out period, working on an 250k upload speed from home, we would be thinking about 20 to 30 mins.
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 have an RSS-reader in one of my webservices. I then utilize the webservice using javascript and everything works fine with small to moderately sized RSS-feeds.
But the webservice keeps timing out when I'm trying to use larger RSS-feeds.
ie. this feed from Youtube: [URL]
Javascript VideoModule = { LoadVideos: function () { var ret = RSSService.GetFeed("http://gdata.youtube.com/feeds/base/users/TheOnion/uploads?alt=rss&
I'm new to this forum, infact this is the first forum i hav ever joined. I need some help urgently as i'm reaching the deadline of my project.I created an asp.net website, where administrator will upload files to SQL database which is connected to the webpage. From the web page there will be a download link to download those uploaded files. I have been successful in uploading files to the database. But nothing is striking in my mind regarding how to download files directly from database using asp.net C#.
