Hi Gerges,
Thank you so much for this first reply
YES, the recoards are sorted with the first field !
I wrote this :
AddObject "newObjects.utilctls.SFMain", "FS"
Set File = FS.OpenFile("\my documents\pda.txt")
and the result is :
Microsoft VBScript compliation error - line 2,cahr 12
cannot use parens when calling a sub
I understand that my call is not well formulated but how openning the file that
is in this diectory ?
What is difference between POS ans SEEK function ?
Considering the size of my datafile I was thinking of using loop seach using
upper/lower comparison with my reading Hexcode and positionning the reading on
middle of previous interval; so this should cut seaching time in something
around 20 reading loop to find the correct line for my 100.000 lines file ; am
I right ?
Is ther any book or literature in (better in French) about NSBasic avaialble ?
Many thanks again for your precious help
