'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Reference the AdventureWorks database.
Dim db As Database
db = srv.Databases("AdventureWorks")
'Define a FileGroup object called SECONDARY on the database.
Dim fg1 As FileGroup
fg1 = New FileGroup(db, "SECONDARY")
'Call the Create method to create the file group on the instance of SQL Server.
fg1.Create()
'Define a DataFile object on the file group and set the FileName property.
Dim df1 As DataFile
df1 = New DataFile(fg1, "datafile1")
df1.FileName = "c:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\datafile2.ndf"
