In VB.net I have used the Data area in the toolbar to set up a dataconnection, dataadapter and dataset to a sql database. In the code I use patronsda.Fill(Patronsds1) to fill my datasets. Does this hold a connection open? I see alot of code with conn.close and conn.open i havn't had to use any of them. Just want to make sure I'm not hurting the database.
