How to Upload big file size in asp.net ?
I have an application that lets the use upload a pdf, I wanted to put a limit on the size the pdf can be. If the user tried to upload something too big I wanted to display a message to the user. I am trying to use a custom validator where it checks the size of the file and if it is too big it will set the "IsValid" to false. Is this the correct way to go about doing this? Is there a better way? When I test it, everything works in IE 8 and FF, but it does not work in IE 7 and can't figure out why.Here is what I have so far, this is on my aspx page:

And this is the code behind:
[Code]....
In my application the user uploads three files ( Resume, Cover Letter, Selection Creteria).
I want users not to upload more then 4 MB files, so In my web.confing file I have allowed max of 5 MB. <httpRuntime maxRequestLength="5000"/>. I did this so that I can validate the file and give user a message that they are trying to upload more then 4 MB file.
It all works fine if the user is only uploading resume. But if the user uploads all three files of size 4MB then my validation does not work and it goes to connection time out.
How can i handle the validation to check the file size of all 3 files?
currently we are configured execution Timeout="1200" (The default is 110 seconds) and maxRequestLength="12288" (The default is 4096 KB)but some times users upload files above 12MB so we are getting "Maximum request length exceeded" error.we are checking the file size using client side javascript ActiveXObject object. but ActiveXObject only works in IE not in others like mozilla,crome,..Jacescript Code are

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?
I use fileupload control to upload image below is code:

My client is uploading file more then 1 GB through application. I know i can only upload only 100mb using asp.net MVC application.

i am getting error at byte[] data = new byte[st.Length]; because st.Length=1330768612
Error - "Exception of type 'System.OutOfMemoryException' was thrown."
Is there any way i can upload more then 1gb file?
Why we can define maxRequestLength= 0 - 2097151 in webconfig,
So we're having this problem. A user goes to upload a file, and if it's above 10MB, it just kind of times out the page, and clears, and no good error is thrown to describe what happened. Ideally, we would like to examine the file size when the user chooses the file they want to upload but I don't know if this is even possible. Our framework is built with ASP.NET, VB.NET, and Javascript (and ExtJS 3.0), and it runs in IE.
