Guys

I'm new to all this .net business. I'm currently building a bulk mailer and want to make it usable from a number of different datasources (text, csv, excel, access and sql server). I've got it working with text and csv and am currently working on the excel option however before I go on I want to know if there is a ready-made component that I can use to present the user with the option to choose any data source (oledb, ado, text etc).

Thanks
