Hi Peter,

It is actually the default file: idapi32.cfg which is migrated with the 
BDE into C:\BDE32 unless you customize the installer with your own 
target location (which you can do by modifying bdesupp.ini).

and yes I know paradox weirdly allows you to specify a specific cfg file 
to use at launch but as I have said many times way back in the past, 
this actually causes issues when there are multiple BDE applications 
running at the same time. Sometimes even the "multiple cfg files in use" 
error.

Best practice is to allow the BDE to use the default idapi cfg and then 
check/set the specific setting you require (even MAXHANDLELIMIT) at 
runtime via the API (and not by directly reading/updating the Registry, 
a big no no)

I even check that Local Share is TRUE when my application launches for 
example.

FWIW
Leslie.
