changing native driver settings via code

Does anyone out there know how to check and set BDE Native Driver info
through code for MSSQL?  I can set the check and set Local Share and
similar properties through Delphi code but I don't know what exactly to
do for native driver settings (specifically schema caching for MSSQL).
I need to check these setting when the app loads and change them
immediately if they're not correct.  Any help would be greatly
appreciated.

TIA,
