VS 2008 Working With Datatables Created In Code

I'm working on making a game using VB, and part of the game involves being able to cast magic. What I did was put all the magic spells into a table in a database with the various properties I'll need at one point or another.The problem is that I need to only be able to select from a list of certain spells (Namely those your character is strong enough to be able to cast), and have it display the cost of the spell in a text box. My way of getting the right spells was as follows..first mak the structure of the table: [code] how can I use that usableSpells table I made as though it were in a database (IE making a textbox have something like "usableSpells.Spell_Cost" and making it display the relevant cost)? Trying to do it directly gives me "'Spell_Cost' is not a member of 'System.Data.DataTable'.,
