I'm not sure what exactly you mean by an edit box. Ways of reading csv
files have all kinds of tradeoffs. I personally sell a component
designed to read csv files correctly and quickly,
http://www.geocities.com/shriop/index.html . There are other options,
like the Jet driver or the Microsoft Text Driver, but these are not
very quick or efficient as I describe on my benchmarks page. As for how
to display multiple csv files at once, you'd have to give a better
description of the application. It shouldn't be anything different than
wanting to display the contents of 2 different tables at once, but this
seems like a kind of rare situation. I'd just recomment multiple data
grids, one for each csv file. Now if you were wanting to get up to
displaying like 10 at once, you'd probably want to have like a tab
interface, or maybe a tree view that loads the data grid with the
corresponding data, but again, you'll have to give a better description
of the problem.
