> Are you sure this cant be easily done? No, I'm no web expert. We've not found a way so far, and I've not seen something like this on the web, but I'd be happy to be proven wrong. edit: to clarify, I don't doubt one can get 150 fields in a view on the web. But can one dev do it in one day and have it look great?
I know nothing about Delphi, but I guarantee that I could take any UI you designed in a day in Delphi and get something equivalent on the web in the same amount of time. Sticking a bunch of inputs on a page (even with some nesting) isn't complex at all. I think you are doing your customers a great disservice by not learning about web development.
Win32 is bedrock, the web is quicksand. Look at "HTTPS everywhere" and "you don't need FTP any more", which did little in terms of actual security, but broke almost everything in some small way.
The web doesn't value legacy. It's a petulant 22 year old, that thinks it knows everything, and does stuff deliberately against the advice of those with more experience.
