ftp file pointers - help
|
|
|
| Help!
I am trying to write to a file on the web. I am using InternetWriteFile, is
there a file pointer function so that I can go to a location in the file and
write to it? Or do I have to keep writing the whole file?
Any help would be appreciated.

| For wininet related questions use
microsoft.public.inetsdk.programming.wininet NG.
InternetWriteFile does not support setting file pointer, you may use file
pointers only for reading from the web (InternetSetFilePointer with
InternetReadFile).

FTP protocol does not support writing arbitrary portions of the file.
You can append to the end of an existing file with APPE command. See KB
Article KB182316 "INFO: FTP Append Functionality not Available from
WinInet".

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925

| Thanks.
Is there another way of writing to a file apart from ftp so that I can have
a file pointer?

What are you trying do to? What is your server capable of? Do you have
any control over the code running on the server?
If you have a local copy of the file that is very similar to a remote
copy (perhaps you downloaded and modified it) and you want to
synchronize the remote copy, look into setting up an rsync server:
http://www.samba.org/rsync/
