Your users enter a string to txtText1 and click cmdBtn to do a search for say name in rsData

Private cmdBtn.Clink....
'
' Test user entered something
'
If len(trim(txtText1)) > 0 then
rsData.FindFirst("Fieldname = '" & txtText1 & "'")
if rs.nomatch then
.
else
data found do whatever
end if
.

You can shorten this with the use of SQL to do a complete sweep of the recordset. If you want an example email me at [email protected]
