Dim srv As Server
srv = New Server

'Reference the AdventureWorks2012 database.
Dim db As Database
db = srv.Databases("AdventureWorks2012")

'Shrink the database without truncating the log.
db.Shrink(20, ShrinkMethod.NoTruncate)

'Truncate the log.
db.TruncateLog()

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
