Hi there,
I've been reading all I could find on the control 'input type=file' and all
the trouble that it comes when uploading large binary files (>4MB) to a DB
server or server path.
I've seen plenty of examples about it, and they all agree that to make
possible the upload of those files, it's mandatory to change the web.config
(or machine.config) for the maxRequestLength attribute of the <httpRuntime>
element.
What I'd need though, is a way for NOT allowing content larger than those
4MB to be uploaded. I've tryed the following on my code, but it's not
working (probably because I've also read that when submitting the webform,
the content is already sent to the server, thus if you send 50MB you'll have
to wait until the server returns an error)
if( FileInputAttachment.PostedFile.ContentLength ) > 1024
{
//change a label text to display an error
}
Is there a way of querying for the PostedFile.ContentLength BEFORE posting
the data to the server? This way I could warn the users not to upload files
larger than a MB or so...
Thanks!! 4 1215
Hi ricardo,
Wiothout some sort of ActiveX control or Java applet on the client side,
there is no way to determine the length of the file prior to upload. The
input only contains the path to the file to be uploaded on the client.

I feared so...Do you know of any third party (and hopefully free) ActiveX
control I could use?

HTTP expectations (status code 100) are meant for that purpose,
although it still requires a (cheap) roundtrip. And it also requires
your web clients to play along nicely -- I have no idea if IE or
Firefox even use this header before posting (large) entities.
System.Net.HttpWebRequest does by default.
