DirDetails() vs dir()

Question

I have a program that iterated through files in a folder on an FTP server.

3 weeks ago it suddenly stopped finding files. There were no updates to the program. It worked for 4 months and one day it just stopped doing it. DirDetails always returned 0 files.

I replaced the code with the Dir() method and everything worked again. I included code below. (warning evil VB.. ;-) )

What could have caused this?

It is possible that there was something changed on the FTP server itself. How ever I don't have control over it.

Thanks
Wouter


<code>
Dim ftp As New FTPClient(FTPHost)
ftp.ParsingCulture = New CultureInfo(FTPLocale)
ftp.User(FTPUser)
ftp.Password(FTPPass)

ftp.ConnectMode = FTPConnectMode.PASV
ftp.TransferType = FTPTransferType.BINARY


For Each file As String In ftp.Dir(TARFolder)
' This code works
Next

For Each file As FTPFile In ftp.DirDetails(TARFolder)
' this loop is never done since DirDetails fails to find files.
Next
</code>

Are you sure there are visible files present in "/"?

What does typing "dir" in a command line FTP client give you?

Answer 7

sure ! 43 files and folders !

dir in / :

drw-rw-rw- 1 ftp ftp 0 May 22 00:27 .
drw-rw-rw- 1 ftp ftp 0 May 22 00:27 ..
dr--r--r-- 1 ftp ftp 0 May 22 00:33 Mes images
........

but other problem is that dir("/"); returns 0 files
only dir(); works !

Answer 8

i think i found the problem !
the FileParser :
we have to detect the good Parser to use

for example, connect to ftp.antesis.org, use :
FTPFileParser parser = new UnixFileParser();
FTPFileFactory fileFactory = new FTPFileFactory(parser);
client.setFTPFileFactory(fileFactory);
client.setParserLocale(Locale.US);
--> dirDetails("/"); works !!!

but with client.system(); this server returns
215 UNIX Type: L8
and my local server on windows xp returns
215 UNIX Type: L8

and this FileParser configuration doesn't work
i think we can't use system(); to find the good parser to use

then how can i find the good FileParser which is different for differents servers ??
