Mosaddeq,
You are referring to an Incremental Search. That is not possible in Access
if you are trying to enter data directly into a table. As Rick mentioned it
is possible if you are entering data on a form. The easiest way to implement
an Incremental Search function on a form is to use a ComboBox. It is also
possible to implement an Incremental Search function using a text box on a
form but that requires a high level of VBA experience. If you must have this
function then a ComboBox is usually the better way to go.
A note of caution: An Incremental Search works very nicely in Excel because
the records are probably in main Memory at the time that you are doing the
search. That is not necessarily true in Access. The records will usually be
on a hard drive. This means that a good typist will type faster than the
system can respond and the results are unusable.
This problem is particularly acute for a workstation on a network. Even a
poor typist will overrun the system response time and the users will cease to
use the function. You may very well end up wasting your development time
pursuing this function.
