Nadya,
I'll send you the shell of a page using the code. You simply set it up, and if the user does not have the necessary controls they are downloaded.
It works great - however the project I was on had to support Macs, and IE on the MAC does not support active-x. We ended up with a much more expensive solution ($1500 a server on a web farm vs $150 for the whole package from Chado. It is real nice, though the documentation is a bit lacking. If you need help, drop me a line.
