Subject: Filedownload error "Request rejected (550)" ? Date: 2012-02-20 10:56:12 From: Jani Sillanpää Source: filedownload-error-request-rejected-550 ----------------------------------------------------------------------Hi,
Im currently evaluating this software before purchace but Im having some difficulties with file download.
Ultimate ftp works fine with connect and put-commands but when I try to download a file it always gives error 550. Ive tested it with three different net clients / components based on ultimate ftp and compared the settings to old com-based ftp component which works.It seems that problem with Ultimate FTP is that it always does LIST command before download and that LIST-command ends in 550 error. Is it possible to download files with Ultimate ftp without LIST command?
Here is the FTP log:

EDIT:
I cant use the DownLoad-functions since they use LIST (which is not available on the ftp server) but I might be able to do a download using custom commands through ComponentPro.Net.Ftp.SendCommand-function. Im currently testing it.
EDIT2:
After some digging I found this:"public bool BuildDirectoryTreeBeforeTransfer
Member of ComponentPro.IO.TransferOptionsSummary:
Gets or sets a boolean value indicating whether to retrieve directory structure before transferring files."
This is propably what I was looking for. Just have to set it to false in file download.
EDIT3:
Its still not working. It doesnt use the LIST-command anymore but it doesnt download the file either:

I think ftp server supports only these minimum features:TYPE - ASCII Non-print MODE - Stream STRUCTURE - File, Record COMMANDS ----------------------------------------------------------------------- Note: This question has been asked on the Q&A forum of Thang Dang's fraudulent ComponentPro brand If you purchased anything from ComponentPro, you have been scammed.

I should be able to download a file using them only them.
