Change SQL Server Authentication method programmatically

Hi,
Does anyone here know whether it is possible to change the
authentication method of a SQL server instance programmatically, rather
than going through enterprise manager.
I am using SQL-DMO (under C#) for some other things, but the
documentation is so bad that I can't find out whether what I want to do
can be done. I have also tried googling but came up empty handed.
I hope that someone can help me.
Cheers
JonoThe only thing I know about, though I am not quite familar with SQL-DMO is
to change the regkey:, using the XP xp_regwrite
For registry changing try this regkey:
Default instance:
" HKEY_LOCAL_MACHINE\Software\M_icrosoft\M
SSqlserver\MSSqlServ_er\LoginMode"
to 2 for mixed-mode or 1 for integrated.
HTH, Jens Suessmeyer.

This is a VB solution (with SQLDMO). You'll have to translate this to C#
yourself.
On Error GoTo ErrSec
Dim srv As SQLDMO.SQLServer2
Set srv = New SQLDMO.SQLServer2
' integrated security login
srv.LoginSecure = True
' or standard security login
srv.LoginSecure = False
srv.Login = "sa"
srv.Password = "MyPassword"
srv.Connect "MyServer"
' switch to integrated
srv.IntegratedSecurity.SecurityMode = SQLDMOSecurity_Integrated
' or switch to mixed mode
srv.IntegratedSecurity.SecurityMode = SQLDMOSecurity_Mixed
' restart server: shutdown looses the connection and generates an error.
' we catch that error in the error section and restart the server.
srv.Shutdown
Exit Function
ErrSec:
srv.Disconnect
srv.Start (True) ' true reconnects automatically|||See SQLServer->ServerLoginMode()
