"Data Source=C:\ASPNET20\data\Northwind.mdb"
Dim dbConnection As New OleDbConnection(connectionString)
dbConnection.Open()

Dim commandString As String = "INSERT INTO Employees(FirstName, LastName) " & _
"Values(@.FirstName, @.LastName)"

Dim dbCommand As New OleDbCommand(commandString, dbConnection)

Dim firstNameParam As New OleDbParameter("@.FirstName", OleDbType.VarChar, 10)
firstNameParam.Value = txtFirstName.Text
dbCommand.Parameters.Add(firstNameParam)

Dim lastNameParam As New OleDbParameter("@.LastName", OleDbType.VarChar, 20)
