Got it downloaded and we will put that to work right away! We purchased a .Net twain control set for a custom written application using cameras about three years ago. We found Vintasoft in an Internet search. When we updating the software, we purchased the newer version that we needed.

Our developer had said it was well written code. Thank you once again.
