Creating DAO Interface for Custom ISAM

[GopalGokhale]

Sir,
I have a problem as under :
01. I am developing a big system which should support ANY database
at wish of a cusomer ( Say Btrieve,Custom ISAM
etc.). The code is in vb6 and for developement purposes we
are using DAO for MS ACCESS (DAO 3.51)
02. I have an excellent custom ISAM which gives a dll supporting
normal read/write/update/delete options on indexes
03. But the said ISAM does not have a DAO/ODBC interface and
datafile contains index pages as well (like Btrieve)
It is not a RDBMS
04. I would like to retain code of application programs. The
application does not define RecordSets directly but get the
Recordset through a activex dll and thereafter the
application uses DAO syntax like .movenext .update etc.
05. Is it possible to connect the custom ISAM/Database DLL to DAO
engine so that I get a recordset and thereafter
I will use normal recordset syntax using ISAM dll in the
background
I shall be greatful if you can guide me in the matter
Thanks and Regards
