Hi to all,
I'm a JScript user, but this time I've a problem with someone else
code, written in VBScript. The problem is: using the script I join to
force the download of a .pdf file, works fine except with a certain pdf
file of 7 mb: with this very pdf, it results in a zero byte download.
The file is not corrupted and opens finely in Acrobat if I download it
the usual way. The problems arise only when downloaded via this -
usually well working - script. The application is not mine and I cannot
rewrite it in Jscript :-D. Any idea or suggestion? Thank you alot!!
J.
PS the fact that the file is bigger than usual can count?
