Get The File Size Before Uploading Perhaps Using AJAX

Mar 15, 2011 03:11 AM

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 02, 2010 06:16 AM

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 01:44 PM

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 11:37 AM

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 01:43 AM

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?

Configuration :: Uploading File Using Fileupload To Another Server?

Oct 12, 2010 04:21 PM

I am using the fileupload control to upload an excel file to a server, but I am getting a
"Access to the path '\<server>importResponses.xls' is denied" when I try to use fileUploader.SaveAs(filepath). The filepath I use is \<server>importResponses.xls, so I am actually saving it to a share on a different server.My environment consists of a web server and a database server. I am trying to upload the excel file to a share on the database server. A stored procedure then takes that excel file and imports the data from it into a table. So the problem isn't with being unable to save a file to a share on the web server, but it's a problem with being unable to save a file to a share on the database server. It used to work, but now it doesn't and I have no idea why. What process(es) on the database server do I need grant write access for in order for the fileupload control to successfully save the excel file?Right now, I only have the Network Service account with read/write access to the share on the database server. I tried adding other accounts, such as the ASPNET and IUSR_<server name> accounts, but nothing seems to work.The web application that does the actual uploading is configured like this:

<authentication mode="Windows"/>
<identity impersonate="true"/>

Could that have anything to do with it?If you're asking why I'm trying to save an excel file on the database server instead of on the web server, this was the only way I got this to work. If anyone has a better suggestion on how to programatically import excel data into a SQL table, I am all ears.
