Dear Ramesh,
in my old post slowness You write this

A small suggestion to you to try.

can I send you a private mail containing a very little source code?and a question?

These are decisions of your customer I think.
The question is: your application will remain as fast as it currently is?
Do they have good connectivity?

Have a nice day

Silvio,
have you some records in which the year of field named "data" is 2024
In the screenshot I see 1971

Bye

Silvio,
what return code do you have?

Some benchmarks using a table opened by other user containing 6000 records indexed in a lan
0.06 seconds using Enrico's technique and 11.57 seconds using a normal DO WHILE !EOF() ; SKIP ; ENDDO cicle

If table is opened only by this test program the speed is the same 0.06 seconds

Thanks Again

GOTO aRec[ i , 1 ]
NEXT i

and not by this one that is very slow if cdx is opened by other person

DO WHILE !EOF()
SKIP
ENDDO

But I would hope that ...

Hi to all,
I'm wondering which is the best/fastest way to load an array containing all records numbers in a dbf table indexed by a particular order
Obviously not this one ot this one because as written in my previous post it is very slow if opened by other users.
I don't know how cdx are ...
