Need help on ADO connection with DBF file performace.

Asked by alphaau in VB Database Programming

Tags: dbf, ado, connection

Dear all,

     I've got a problem on ADO connection with foxpro dbf file. i use a udl file to point to the dbf file, that's fine.  But the problem is the access is very slow, it use about 5 min to run a select statement, can someone throw me some light on how to improve the performace?

The dbf file is 700Mb and containing more than 600k row of data.
the connection is using:
Provider=MSDASQL.1;Persist Security Info=False;Extended Properties="DSN=PVoucher;UID=;SourceDB=c:\;SourceType=DBF;Exclusive=No;BackgroundFetch=Yes;Collate=Machine;Null=Yes;Deleted=Yes;"

i was told that the performance would be better if i use the seek/seek and replace method than the select/update method, is it true?

Thx in advance
