I have a desktop app that I'm making and I want users to have to login before the program can be used to its fullest extent. I have created a database on www.winhost.com (where my site's hosted), but now I don't know what to do. I've been on google and msdn and I would like to know how to programmatically add new rows/colums to this new database which is currently empty. And how I can update the database with new account info/get information from it.
I'm not expecting code or anything, just maybe a few good simple tutorials or something, since I haven't found what I'm looking for yet...
