Re: FN-FORUM: classic asp and file uploads

date posted 24th July 2007 13:06

Hi Guys,

I used to work on secure networks for the MOD, so we were never allowed to
use third party tools, only what came with NT/2000 server. This mean't we
had to script everything by hand. To prevent you from going through the same
heart ache as myself, here's a rough set of instructions to upload files
with ASP.

The first place to always look for ASP stuff is this respected website,
here's the link which gives information on ASP uploads:

http://4guysfromrolla.com/webtech/LearnMore/Upload.asp

Another place to look, is the W3Schools website, it's a superb site for
beginners to advanced guys. It's like the little black book us developer
geeks carry in our smoking jackets top pocket. This link gives an insight
into ASP's file objects:

http://www.w3schools.com/asp/asp_ref_filesystem.asp

Last of all, this is Microsofts way of uploading without third party tools.
It takes a file, then using HTTP post, reads the file as binary and
reconstructs it onto the webserver. Now word of warning, make sure you test
the file type, as you could upload anything! Also make sure you've setup the
MIME types to allow upto a certain file size limit. I think it's set to
something silly like a meg as default. Anyway here's the link:

Now if you've got your head around those, I'll give you the AJAX. But first
make sure the aboves working, as AJAX is a headache. Then we'll go the next
step.
