How to put a big file into a variable?

[Raymond H.]

Hello,
I'm not able to put a big file (600Mo) into VarDonnéesDuFic hier3 .
With the MsgBox line, VarDonnéesDuFic hier3 displays zero (o). Where is my
problem? Is there an other way to open a big file (600Mo) into
VarDonnéesDuFic hier3 (with the special data like a mpeg) ?

Dim VarDonnéesDuFic hier3 as String
NumFichier = FreeFile
Open Text2.Text For Binary Access Read As #NumFichier
VarDonnéesDuFic hier3 = Space$(LOF(NumF ichier))
MsgBox VarDonnéesDuFic hier3 'VarDonnéesDuFi chier3 gave zero (0) with a 600
Mo file.
Get #NumFichier, 1, VarDonnéesDuFic hier3
Close #NumFichier
=============== =============== ==========

Uh, yea, no kidding! For a messagebox, try 250 or so characters, not 600mo
(whatever a mo is).

To open and read a large file use Binary file access and do the reading in
chunks of 64k.

Hello,
mo is MegaBytes in french (MB). Do you have an axample about your
'chunks of 64k'?

Why would you want to ??? No human will like to read 600Mb just
like that ;-)

And in a Msgbox ???

Did you try using a Richtextbox instead?
Maybe there is a better way of reading 600Mb worth of data. If you elaborate
why you need it in a continuous string maybe someone can figure out an
alternative way.
