Thread-topic: FTP with URLSimpleDownload isn't working for me
Hi,
I'm developing a
plugin for Adobe Acrobat 6.0 that needs to use FTP to fetch some data files
from a server on the LAN.
Since Acrobat 6.0
plugins are based on Carbon, I have been trying to get URLSimpleDownload
working, but keep getting errors. In my testing, I have found that file:
and http: URLs work fine, but ftp: URLs don't. They typically return a
result code of -30785 (Extension failed to load).
And to top it off,
I'm not even sure if URLSimpleDownload would do what I need even if it was
working.
Ultimately, what I
need to work is this:
- Login to
an FTP server on the LAN using a username and password (not
anonymous).
- Get a listing
of a specific directory relative to the server's root directory which
is *not* below the logged in user's home directory. (can an ftp: URL
even do this?) The logged in user does have permission to list this
directory.
- Download data
files from that directory in ASCII or BIN mode, selectable by
me.
Details about my
environment:
Mac OS X
10.3.7
CodeWarrior
9.3
Adobe Acrobat 6.0
SDK
XCode 1.5 is loaded,
but I'm not using it directly.
Other things I've
tried:
- Apple provides
sample code for doing FTP using CoreFoundation, but I can't use it because
Acrobat 6.0 Plugins aren't Mach-O and thus can't use any of the .framework
stuff. (Unless I'm missing something here...)
- I found source
code for a command line FTP client written in ANSI C using direct sockets
calls, but it's such a mess that I'd have to rewrite the whole thing to do
anything useful and I'd just as soon avoid that if at all
possible.
If anyone has any
thoughts or suggestions on how I can get something working that satisfies my
project requirements, I'd really appreciate it.
Thanks,
Terry
