FileUpload Web Control Can't Handle Large Jpg Files (5MB)?
Jun 22, 2010
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?
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..........
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.
There is a requirement like in a web page having FileUpload control and button. I need to upload excel records to sql database. If the excel file having less than 1000 records then it is executing fine and if the excel file having more than 1000 records then it's giving me the error message like bad request (error code: 400). As per my requirement need to upload minimum 4000 to 5000 records on button click. Some times it is working fine in IE browser but not all the times. In mozilla not at all working if records having more than 1000. How can i over come this issue.
Can I upload files without having a fileupload control? I was looking at the HttpFileCollection class, but I believe that only works with the fileupload control.
We need to upload multiple files using ASP.Net in one go. One option is to use the ASP.Net FileUpload control but it seems that it can't upload multiple files in one go. Any other option or ASP.Net FileUpload control can do multiple uploads in one go with some tuning?
I'm trying to use an asp:FileUpload Control to allow users to upload files (.doc, .gif, .xls, .jpg) to a server that is outside of our DMZ and not the Web Server. We want to have the ability to look at these files for viruses, structure, etc prior to saving them into another directory that would allow access to outside users. From what I have read about this control is that it will allow for files to be uploaded to the web server. Can this control be used to upload files to a server other than the web server? If it can be done where should I look for this type of functionality or how do I force it to go to https:servernamefolder name (Where server name is not the web server)? Would I have to read the file then write it to the other server?
In continuation to my previous research at this link : Security Risks or concerns with the use of FileUpload control of asp.net - how to Scan files during upload, also how to intimate user if file is virus affected and abort the operation. In addition to above, we have McAfee Antivirus installed on our servers. I heard that there is some APIS for this work for Symantac Antivirus but I am not sure about McAfee antivirus.
In my website,I have a home page in which by clicking on an image button,I get redirected to a different .apsx page .This page consists of a FileUpload control and 2 buttons(ATTACH,CANCEL).When a user selects/browses a file from his local machine and click ATTACH button,I display that file in a GRIDVIEW and also push the details of that file like Filename into a DATATABLE. The user in this way can browse multiple files and all of them are added to GridView and also pushed to DATATABLE.Now when the user clickes CANCEL button,I am sending the whole DATATABLE in a session object to the HOME page.Upon clicking SAVE button in the home page,the files in the DATATABLE must get stored in a physical location that I mention in the code. The problem that I am facing is that when I write
The files are not at all getting saved in the location. However If I pass the FileUpload control using Session from the second page,
FileUpload fl=(FileUpload)Session["FileUpload"]
The files are getting saved with the correct filenames but the content of all the files consists of the content of the latest uploaded file.I know what the problem is but unable to get a solution. My Requirement is to save the files in a physical path only after clicking the Save button in the home page.
I have a webpage where by user can upload jpg file through browse control on my server. Functionality working fine.
I have concern that if any one create virus and assemble it in a form of jpg and upload it on my server which can crash the hard disk or any other disaster.
the first file selected uploads perfectly - every subsequent file is 0bytes. The code for the upload button is presented below.
Protected Sub cmdUpload_Click(sender As Object, e As EventArgs) Handles cmdUpload.Click Dim hfc As HttpFileCollection = Request.Files For i As Integer = 0 To hfc.Count - 1 If i < 9 Then team = "/Team0" & i + 1 & "/" If i > 8 Then team = "/Team" & i + 1 & "/" Dim myFtpWebRequest As FtpWebRequest
I had implemented FileUpload code. In which for every particular Id, it creates Folder/Directory (if not exist) on Page _load.Then inside that particular Id's folder it will upload single or multiple files.
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.
Please help to understand this RegEx statement in details. It's supposed to validate filename from ASP.Net FileUpload control to allow only jpeg and gif files. It was designed by somebody else and I do not completely understand it. It works fine in Internet Explorer 7.0 but not in Firefox 3.6.
[URL] .... I am referring to the link given mentioned above, i want to save image details into database of each file, if i select two files i want to save filename in database in each row. ist file in 1 row , second file in next row with file name.
I have a standard ASMX web service which uses a lock object to process the first request it receives and reject other requests that come in before processing completes. The web service is hosted on a Windows Server 2003 box with a single-core processor. To test whether this works as expected, I wrote a client that spawns 100 threads. Each thread makes an asynchronous POST call to the web server (i.e., HttpWebRequest.BeginGetResponse()). From my own logging, what I'm seeing on IIS is that two threads are spawned. Let's say thread IDs 1 and 7. Thread 1 is assigned a small number of requests. It accepts and processes them, one after another. Thread 7 is assigned a large number of requests. It rejects them. Does anyone have theories on the following: Why are two threads spawned? And not four or a hundred? Why does there seem to be thread discrimination? Thread 1 looks like it has control of the lock object at all times.
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.

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.
