Is there a way to do this (I hope that someone understanding my problem !!!) ??? Thanks Silvana Back to top Jayme Jeffman Filho Guest Posted: Tue Nov 16, 2004 11:29 am    Post subject: Re: New connection Hello Silvana, You just have to drop down a TDatabase component, if you're using BDE, and set its properties at runtime. This is quite simple when using dBase or Paradox database systems, if you're using ODBC you should first set up an ODBC DNS at runtime. HTH Jayme.

I must open an Access dataBase, but one time the name is Dati.mdb, another time is DatiX.mdb, ... (the operator choose the name run-time); I try with a TDatabase object and I put DriverName=Microsoft Access Driver (*.mdb) and DatabaseName=Dati.mdb, but when I try to connected, compare the message "Invalid parametrs". You wrote that I must set up an ODBC DSN at runtime but ... I don't know what can I do this !!! Can you help me again ?

Earlier versions of MS Access require an ODBC connection or you should use ADO connection components, which I've never used, also I've never set up any ODBC data source at run time, I only know how to do it at design time. Take a look at OTL : http://otl.sourceforge.net/home.htm and Jerry Bloomfield's Code Central at : http://cc.borland.com/ccweb.exe/ I bet you'll find out a solution . HTH Jayme.
