If you are connecting to a SQL Server database you can create a connection object like this:

Dim con As SqlConnection = New SqlConnection("Data Source={db server};Initial Catalog={Table};User Id={ID};Password={password}")

replacing the {} with your database specifics.

You can then create a command that contains the SQL you want to execute against the database:

Dim cmd As SqlCommand = New SqlCommand({Query}, con)

The query is just a string type, e.g. "SELECT * FROM dbo.Users WHERE UserID = '123'"

Then execute the query, e.g. if you are returning a dataset:

 Dim dt As DataTable = New DataTable()
            Dim da As SqlDataAdapter = New SqlDataAdapter(cmd)

Or if you are not returning anything with your query use:


MSDN will be able to go into allot more detail.

You could use OLEDB, ODBC types of connection objects instead of SQL but the same logic applies.
