My experience with VB# in this area is pretty much null, but if
Server.CreateObject works in ASP.NET the way it does on classic ASP then
"iPower" is definitely not a valid progid and that's what the error is
telling you ("the object is not registered").

You need to use a fully qualified ProgID, like "ADODB.Recordset" or
"Scripting.FileSystemObject"
