[[ASP]] is about creating applications that work on the internet in a web browser. To create applications that work in a web browser, then you will need to generate [[HTML]] and use a web server (to use Visual DataFlex you will need [http://en.wikipedia.org/wiki/Internet_Information_Services IIS] ) | [[ASP]] is about creating applications that work on the internet in a web browser.
