Web Forms :: Uploading Large Files Results In Page Cannot Be Displayed
Dec 9, 2013
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" ...
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.
My Development Server has: Windows 7 Home Premium 64 Bit IIS 7.5 ASP.Net 4.0
When I attempt to upload 1 file under 4mb, everything works wonderful When I attempt to upload 1, 2 or 3 files with a total size under 4mb, everything works wonderful When I attempt to upload 1 file, over 4mb or When I attempt to upload 1, 2, or 3 files that total over 4mb, a problem arises! And Continue to read and not assume it's just my Web.Config file, for I did attempt to set the maximum upload size to higher than 4mb, a copy of my Web.Config is included below!
Here is my Problem:
I have a need to upload 3 Files, 1 File being a .jpg file and the other 2 files will be .mp3 files. If I try to upload 1 file that is over 4mb or if the sum of the 3 files is over 4mb, I get a> The Regular Debug Message:
Maximum request length exceeded.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: Maximum request length exceeded.
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
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..........
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 designed a web page in that i'm getting the query and executing the query, if a single user enters some query then the time won't be a matter, but if more than one person is accessing the webpage, then it will make delays to execute the queries,
how can i improve the performance of this page like making the results to be displayed more faster?
I am facing the issue "The page was not displayed because the request entity is too large."I am using ASP.Net 3.5, Sql server2008, IIS 7.5 and OS Windows 2008.I am finding the issue on following scenario:1. The error only shows up if the page is viewed as HTTPS (SSL).2. After login in the application if user waits for 1 min or more before doing a postback.Page size is about 200kb. It is running quite fine on Http.
I have one page that has a FileUpload control with a "Upload Photo" button and underneath that is a ListView control. I would like for the user to be able to browse for a photo and when they click the "Upload Photo" button, that photo displays, along with text boxes that are linked to my database (title, description, photodate) in the listview. The user can then repeat the uploading so that the user can upload as many photos as they want and they show up in the listview (all of them). After the user has uploaded all the photos he wants and has filled out all the information into the boxes of the corresponding photo, the user will then click a button ("Publish") the will publish all the photos that are in the listview.
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.
When we include Javascript files in our aspx files. either we write all the Javascript code in the Head section of aspx or we link to an external Javascript file.
So when the clinet makes a call to that page. Does that mean that all the Javascript will be loaded on the client side?
If that is the case then does not that mean that it will slow down the loading of page as all the Javascript has to be loaded on the client machine?
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.
I have a simple update query to a access database. Works perfectly on my localhost but when I upload it to the server it displays this. The weird thing in the "
monstababy.MailingList.btnSubmit_Click(Object sender, EventArgs e) in C:inetpubwwwrootmonstababymonstababymonstababyMailingList.aspx.cs:26" mention of my
local host settings on the server. I have spoken to my host and they have set permissions for the data folder etc but this still prevails. I am positive it
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);..................
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.
