If you want ot get directory listing to get the file size, you are on the
wrong track. FTP has a sie command to get the size of a file. Use it.
Now if you really want to dir list for a file only, most FTP server use the
host file name as filter.

Subject: Re: [twsocket] Ftp-file corruption check
thanks for your kind reply,
but if I go with the stable version of the ICS which does not have XCRC
command support, I used the following code to achieve my aim
(recommended by FPiette),
1- upload file using ftpPutAsync()
2- use ftpDirAsync() and check the size of the file of interest if it is
same on the local machine and on the remote machine.
I used the following pseudo code:
procedure ftpRequestDone();
begin
case RqType of
ftpTypeSetAsync(): Begin
ftpCli.HostFileName:= '2.bin';
ftpCli.LocalFileName:= 'c:\2.bin';
ftpCli.HostDirName:= '/';
.
ftpCli.PutAsync();
End;
ftpPutAsync: Begin
ftpCli.HostFileName:= '2.bin';
ftpCli.LocalFileName:= '';
ftpCli.HostDirName:= '/';
ftpCli.LocalStream:= TMemoryStream.Create();
ftpCli.DirAsync();
End;
ftpDirAsync: Begin
ftpCli.LocalStream.Position:= 0;
SetLength(tempStr, ftpCli.LocalStream.Size);
{Get the directory response of the server into
tempStr string.}
CopyMemory(Pointer(tempStr)^,
TMemoryStream(ftpCli.LocalStream).Memory, ftpCli.LocalStream.Size);
if(Pos(FileSizeInString, tempStr)0) then
ShowMessage('Uploaded Correctly')
else showMessage('upload failure');
End;
...
end;
end;
but the problem with this code is; the server returns the whole directory
content (losts of file) but I only want to get the directory
listing for the specified file, to do that I used ftpCli.HostFileName:=
'2.bin'; before calling ftpcli.DirAsync() but it did not work.
Is there anyway to get the directory listing for the only specified file?
best regards,
Thanks

How to check if a file is either uploaded correctly or not, I know
that ftpCli supports MD5 command, but at the outside world there were
no commercial ftp hosting services that support MD5 command, I only
found one ftp hosting which supports XCRC and this is command as far
as I know, is not supported by ftpCli. (I am trying to build an ftp
client that is to be used to upload files to external ftp host.)

added XCRC command to get CRC32 for file (for servers without
MD5)
So get latest ICS-Beta, it's in both V5 and V6
