If you just want a small bit uploaded to a website... Try making an ASP page with a querystring input that reads pages with ? headers:

mysite.com/myasp.asp?usersInput=something+new

then make your vb6 program use MS INET or the WEBBROWSER control to connect to the asp page and add the small bit of information after the ? ...

or instead of the ? style, try the "POST" method... Probably the easiest way to upload something to the internet...
