Get The File Size Before Uploading Perhaps Using AJAX

Mar 15, 2011

I have figured out that javascript cannot obtain the filesize of a to-be-uploaded file because it is a security risk and it is not allowed access to the clients HD. But I want to see if it is possible to get the file size before uploading the file, perhaps using AJAX.

So by looking at the requests, when you click the submit button on a form that contains a input type=file, the Request actually has the filesize inside of it, so you could therefore get the first request, cancel the request there, and send the file-size data back to the client without actually uploading the file.

I want to do this via AJAX so that it doesn't post back and also without clicking the submit button. It seems impossible to create a submit request with javascript because there is no way to get the file size. But is there a way to fake a submit? How does the submit button get the information? Is there any documentation on how the submit button actually works?

AJAX :: Capture The Full File Path From Async File Uploader Control?

Sep 2, 2010

I have an Async File Uploader control inside a Repeater which is inside an update panel. Now,I am uploading the file into ftp,so I am not uploading the video file,using SaveAs() method. For uploading the file in ftp,I have this UploadFile method which takes these four parameter:FileName, UploadPath, FTPUser, FTPPassword.Now this FileName,I have to send the full file path. My UploadComplete event looks like this:

<pre lang="cs">protected void AsyncVideoUpload_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{//VideoPath is a session variable
VideoPath = string.Empty;
if (AsyncVideoUpload.HasFile)
// string filepath = AsyncVideoUpload.PostedFile.FileName;
string filepath = e.filename;//above two captures only the file name,but I want the total path,like c:/MyDocuments/...
UploadFile(filepath, "","test","Value*12");
VideoPath = AsyncVideoUpload.PostedFile.FileName;

Web Forms :: Finding Client File Size Before Uploading?

Sep 28, 2010

I need to upload images from client to server as follows:

1. Server is passing the client a file name
2. Client is checking file extensins to ensure it's an image then issues a __dopostback to the server.
3. Server uses the FileUpload control to save the image on the server.

I have that all covered, but, if image is too large, the upload fails with the following error: 'System.Web.HttpException: Maximum request length exceeded.'

Is there a way to check file size on the client (without the use of ActievX which also errors out), before it is passed back to the server?

AJAX :: Page Is Posted Back Due To Asynchronous File Uploader Control ?

Nov 22, 2010

I am using Asynchronous File uploader ajax toolkit control.I want to get knowledge of whether page is posted back due to File uploader or not in Page_Load event of my aspx page.

For that i tried to use Page properties IsAsync, IsCallBack but even page is posted back on responce of File Upload these properties are false,only IsPostback property is True.

Why IsAsync and IsCallBack properties are false ?

I was thinking that since this control upload files Asyncronously, so atleast on File Upload IsAsync property should be True.But that is also false .

HttpHandlers / Modules :: How To Disable File Checking On The Server

May 30, 2009

I have a httpModule that takes a url like http://www.my-msi.net/Admin and translates it to http://www.my-msi.net/Default.aspx by converting the member name, Admin, to a number and then storing that number in a cookie on the ressponse stream.

Everything works as it should in development, but on the production server, it returns a page doesn't exist error before my httpHandler gets control.

I know that the handler is working because I have a method tied to app.EndRequest that just puts a tag line on every page on the site and that works just fine.

Also, for .aspx and .jpg files the method handling app.BeginRequest simply returns without doing anything, but this seems to be causing a page error to be reported to the end user. This is something the I'd really like to get fixed. The code to skip these two file types is:


So my two questions are:

How to disable file existance checking on the server?

- and -

What is the minimum amount of work that an HttpHandler is expected to accomplish?
