Epsylon's Points.

The code that you both gave me was good code, just not really 100% what I asked for.  A few bodges and it worked great.

Thanks for your help Eps

Thank you too. Always glad to help   :o)

Just for my reference and in case they fix the search engine   :o)

Create access ODBC DSN programmatically

(* NOTE: THIS EXAMPLE IS NOT COMPLETE !!! *)

(*
 This example shows one way to load the ODBC
 Administrator's DLL (ODBCCP32.DLL) to create
 an Access MDB file and ODBC DSN pointing at
 it.  Note that it assumes current directory
 for both the DLL and the MDB, but the DLL
 will be found if in the WinSys directory which
 is where it normally is anyway.

 Similar operation applies to most driver types,
 with some modifications. eg: Access requires
 the MDB file to exist so you can hook the DSN
 to it.

 Note also that the "CREATE_DB" call is an Access
 special (MS Jet Engine) and has other variants
 like COMPACT_DB and REPAIR_DB. For a full list
 see either the Jet Engine Programmers Guide or
 the MSDN and search for "CREATE_DB".

 This was originally written in MSVC6 and was
 ported to Delphi 5.

 Full documentation can be found in the MSDN
 at http://msdn.microsoft.com/.
