I am building an ASP application with many different kinds of components for the user to use in their custom built homepages that they build using my engine. Though my client now wants a sort of Excel component that would allow the user and visiters to work on the browser and sum stuff up just like excel would do, but all through the browser. Also it would save the data somehow in their own folder. Whew! Just wondered if anyone came across anything like that and what sort of possiblities you might think are out there for this app. Thanks for any info.
