[2008] Access DB issues with 2008

OK, so I earned how to connect a DB in school using 2003.
If I'm not mistaken, things are done totally different in 2008?

This was two years ago, so I forget what I did, and I lost the code accidentally, but I had it to where a DataGridView was displaying queries to the table.
For some reason, I can't figure out how to do this in 2008.

Can someone please tell me exactly what I need to be looking at online that will help me understand this? Like the different parts I should be reviewing?

I can't find any good references for starting from scratch, and I'm not 100% sure what I need to start looking up to get going with this.

Well the first thing you need to do is establish what type of database you are trying to access - if its a Microsoft Access database (MDB) then you need to look into using the ODBCClient class but if its SQL server then you need to look into how to use the SQLClient class.
The first thing you will need to do is visit www.connectionstrings.com and find the correct connection string for the type of database you are accessing and set the ConnectionString property of your SQLclient/ODBCClient class accordingly.
