Hi, John

The problem with progress bar and upload from the browser is that the
browser does not have any means -- in scripting that is -- to open and
read the contents of a file.

There are several samples of code in the web that uses ADODB.Stream
(working only in IE), or with some other applet (be it Java, or
Firefox extension).

For security reasons the only way to access a file is through the
INPUT type=file tag. And, as we know, it does not provide any mean of
control over the way it uploads to the server.

The IIS also does not help us there, specially the ASP.NET platform
because it requires to read the whole Request in order to parse it and
present us with all the nice properties that we use in our coding.

Even if you create a custom HttpHandler, writing it from scratch (i.e.
writing a handler that is not an ASPX page) the Request object that
the handler gets is the parsed one.

So from an ASPX perspective, there is no way to upload a file with
progress bar through the browser.

As someone said in another thread here: any upload control with
progress bar in ASP.NET is fake.

If you want to take a look in an Asynchronous Upload, I've one in my
site: http://pjondevelopment.50webs.com/articles/asyncupload.html

It works in both IE and Firefox.
