i have a fileUpload in my web page but it's not supporting all files eg:
when i browse xls file it's working for small size files but when i go for a little bigger files let's say 50-60k it won't work and will give me an offline web page, i have tried the input HTML on server mode and still having the same problem.
Iam using a file upload control for uploading files in my asp.net application. iam using the following code to impersonate the users who do not have permission for the files to upload. The code works fine for all the files, but it is not working for the files which are in desktop.
Code in .cs file:
System.Security.Principal.WindowsImpersonationContext impersonationContext;
impersonationContext =
((System.Security.Principal.WindowsIdentity)User.Identity).Impersonate();
//Insert your code that runs under the security context of the authenticating user here.
impersonationContext.Undo();
In web.config iam using the following:
<identity impersonate="true" />
Im using a file uploader to upoad files to a folder used for upload.But the problem is this folder is a linux folder. I have made it a shared folder so that I can access from windows by samba. So, file transfer is successful when I'm using os but when I try to upload something from my websites uploader to this folder, this process is not successful. I have given all permissions to this folder.Don't know whats the problem.I have used both type of slashes for directory but still it is not successful.

i am trying to upload files through the ASP.NET File Upload control.
Every thing is working fine, except for the fact that when i try to upload the file on the server i am getting an error: (probably some authorization exception).
do i need to give some rights to the upload up there on the server. If so then for which account and do i need to restart the server after giving rights?

I have a form with a few fields that the user has to fill, and then an upload field that allows the user to upload their article (I haven't added the code to check for file size and format yet; trying to get it to save first!)

I know the asp.net file upload control only allows users to select one file at a time, however i am looking for another way using asp.net to allow the users to select multiple files?
View 1 RepliesI am selecting the file in the file uploader and when i press the button,the page gets postbacked and the selected files in the file uploader gets removed. I need to remain the selected file in the file uploader even thought the button clicked.
View 1 RepliesUntil the Dec 29th my website was working fine. Then My fileupload problems started happening. My fileupload page would simply quit and say the page can not be found. I maximized all my timeout settings and that did not work. I called my hosting company and apparently they have no problem using my page to upload files from their geographical area. So then I concluded it might be a network problem. I ran a trace route and could not really figure out where the problem was. So, I have no idea what is going on. Is it possible that my site is being blocked by some black list out there somewhere?
View 3 RepliesI have a simple file input field that utilizes a File.Copy routine to move the file from the local store to the server. This part of the application works fine in staging but in production I had to establish a work around in order to get it to work. I have the users do a Save As on the file they want to upload and then slightly change the name of the file and then it will upload. I do not have to do this in staging with the same file in order for it to work. I am racking my brain as to whether this is a permissions issue or code issue or what.

We are going to start accepting resumes online but I need to know if the uploaded files will be virus scanned before I park them into the database. I thought this would be a server thing but the server admin and the security guy both said they didn't know. We already have a firewall and antivirus software, I just want to know how things work with native ASP.Net controls and not a product to try.

I'm trying to use below simple code for ajax postback. With file upload, neither javascript the "function startRequest" ever triggers, the file control shows null value somemore.Earlier I had Update progress which didn't work with file upload ever so I removed it. Now I just want to disable the button as the file is uploaded and its inputs are processed in the background. Once the response comes back, the "submit" button is re-enabled.But the file-upload with Updatepanel doesn't work at all. What am I doing wrong,

I do not want to change the default settings for file upload, 4Mb is more than enough for the project I'm working on. After quite a bit of searching I found two approaches that were purported to work but neither one is preventing the "Maximum request length exceeded" error. The first approach[see ref. #1 below] performs validation with a custom validator and in code behind on the page that contains the FileUpload control. It doesn't work. The second approach [see ref #2 below] performs validation in the Application_BeginRequest event in Global.asax. The author stated that validation must be handled by this event. Quoting: "The way to get past is to use your Application_BeginRequest event to handle the problem.. This event takes place for each request to your application BEFORE the data has been completely uploaded. Here you can check for the content length of the request and then redirect to the some error page or the same page with some value in session or query string so that the page can show appropriate message to the user." Here is my code from Golbal.asax based on the above. As noted, this approach doesn't work either.
protected void Application_BeginRequest(object sender, EventArgs e)
{
const int maxFileSize = 4 * 1000000; // Slightly less than 4Mb
if (Request.ContentLength > maxFileSize)
{
Response.Redirect("~/FileUploadError.aspx");
}
}
One comment by a reader of the Global.asax approach was that the value returned by Request.Content.Length would include everything on the page, i.e. viewstate, image and text content, etc. I suppose one work-around would be to set the limit higher in web.config but validate for max. file size in code behind, but that seems kind of silly because I'm manipulating the uploaded files (images) to reduce the size anyway; storage space isn't the issue, performance is. Has anyone managed to solve this poblem?

View 2 RepliesI have an ASP.NET file upload control which sits as part of a form. The file upload control is on the content page while the form definition is on a master page across the site. I've added multipart/form-enc to the form on the master page.I'm using jQuery to submit the form as I show a dialog box from jQuery UI.When I post, no file is returned to the server. The file upload control has no file and HttpFileCollection is empty.

This file should be seen such a way that it can be deleted, if i wanted to. And also i should be able to upload another file from the File Upload control.All these files should be uploaded to a location when i use a button click event in the end.

I have a web application which has 2 different versions deployed. 1 is an ASP.Net web forms version and the other is an ASP.Net MVC version
I have a File Upload page which dynamically creates a directory folder for the target location of the file to be uploaded to.
The application is using Forms Authentication for outside users and Integrated Windows Authentication for inside the network users.
I have an issue where a user can upload a file in the ASP.Net Web Forms version fine. But when the same user tries to upload the file in the MVC version the user gets a File.IO permission error.
Here's the kicker: I can upload the same file in both versions. The user is in a remote location but I believe they're still inside the network because they can work on the other parts of the application just fine.
Possible clues: In the event log there's an info that says Event code:4005 Forms authentication failed for the request. Reason: Ticket supplied was invalid.
What would be your initial thoughts on why this is happening?
