Hi,
My goal is to perform a single SQL query (“select xxx from yyyy etc etc”) to a Database over a LAN, using BORLAND C++ 4.5 and managing (runtime) USERNAME and PASSWORD.

I tried 2 methods :

Method N.1) I used “Tquery”, TdataSource and TDBedit components linked togheter and I succeeded but….I need to manage USERNAME and PASSWORD runtime so I’m trying the following method N.2

Method N.2) I’m using TdataBase Component. Although I can Open the DataBase I don’t know how to perform the SQL Query. Do I have to use the Tquery component? In which way? How can I refer the Tquery to the Tdatabase component?
I suppose I have to use the following components :
TDataBase, Tquery, TDataSource and a Data Control such as TDBedit...is it correct?
Can you give me a simple example?

Thank you a lot!

exactly how do you mean manipulating the username and passwords?
Adding users to acces data ????

iff you are wanting to add users while you or enybody else is atached to a database or datatable you will not be succesful only on posting or an updating the database/table ,
