Well, I found the following http://www.devx.com/vb2themax/Tip/18459 and I found some code in Sergey's message:

LOCAL oSQL AS "SQLDMO.SQLServer", ;
  oDatabase AS "SQLDMO.Database"

oSQL = CREATEOBJECT('SQLDMO.SQLServer')
oSQL.Connect(< server name >, < user name >, < password >)
oDatabase = oSQL.DataBases("pubs")
lcCmd = "DBCC CheckDB"
lcMsg = ""
oDatabase.ExecuteWithResultsAndMessages(lcCmd,, @lcMsg)
