Finding beginning or ending of database

[SuperChris9]

OK, to find out if you are at the end or beginning of a database after an sql you would use say:

if objrs.bof or objrs.eof then
      alert("Record was not found.", "No Record", vbokonly)
else
      'do something here
end if

How do you accomplish this in say VB.NET or ASP.NET?
