using input parameter in .NET with ms access database

i've tried to solve the problem about how to use input parameter when i'm using .NET and accessing MS ACCESS database (*.mdb).
for about a day, i look on internet, asked my friend, and blah...blah...
however, there is no answer...
until... enlightenment comes... the answer appears..

i don't remember the www address where i got the solution..
but it's OK..

here the answer:

instead of using @parameter as in SQLServer database, we should use question mark to mark an input parameter

example:
SQL Server 2005:
SELECT * FROM EMPLOYEES WHERE first_Name = @First name

MS Access Database through ODBC in .NET
SELECT * FROM EMPLOYEES WHERE first_Name = ?


may this post be helpful for you who's looking for this problem..
