[twsocket] ICS FTP Client
I'm sure this problem is simple to solve but I am tearing my hair out trying to solve it. Imagine I have an FTP site that contains a folder called Test1. In this folder I have a file called abc.dat and another folder just called abc. So I log on to the FTP site and change the directory (CwdAsync) to Test1. Now I do a directory listing and I get the file abc.dat and the folder abc. So far so good. Now I change the working directory to Test1/abc. I check with PwdAsync that it is correct and it responds with what I could expect. Next I try and do a directory listing on this folder. The response indicates no error, but the stream is of zero size. So something is obviously not right. Next test performed: I login into the FTP site and change directory straight to Test1/abc. Now if I do a directory listing, I get two directories returned, The single and double dot, but still no filenames. Any help much appreciated.

LIST only returns file in the current directory, so unless there are files in Test1/abc it will return a blank directory. If you want to list all files in sub-directories you have to traverse the directory free listing each directory and combine all the results, or use an FTP that lists all sub-directories in a single command, ie the ICS FTP server. You can try my File Transfer Components which are high level FTP and HTTP components using ICS that will list sub-directories and copy all the files with a single command. http://www.magsys.co.uk/delphi/magxfer.asp Angus -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] ICS FTP Client
I may well end up using your components, but in the meantime I need to determine what my problem is here. I use DirAsync to get the directory listing. If I set the directory to Test1 and do a DirAsync, I get all the files and folder names. Now If I set the CWD to one of these sub folders and do a DirAsync again, I get a zero length stream returned. I know there are files in the sub folder as I can see them with Windows Explorer. The curious thing is that when I CWD straight to the subfolder after the Connect event, the DirAsync now returns some data in the stream, but only the dot and double dot folders. Any more clues?

Re: [twsocket] ICS FTP Client
I may well end up using your components, but in the meantime I need to determine what my problem is here. The component includes an EXE demo, use that against the FTP server and the same root directory specifying get subdirs, and watch the FTP commands and responses the component uses to parse the directories. Or use a decent FTP client like FileZilla that lists commands and responses. If it also fails to list the subdirs, the FTP server is faulty or maybe set so you can only see the root directory. I know there are files in the sub folder as I can see them with Windows Explorer. Which does not have any FTP functionality, so is this a local FTP server?

You can browse FTP servers with Windows Explorer, you just need to type the address in the address bar. Ex.: ftp://usern...@ftpserver.com You can even tell it to use passive mode by going in Control Panel-Internet Options-Advanced tab hth -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] ICS FTP Client
I used the demo program from your website in conjunction with Wireshark to monitor what was going on in network land. I then tried my program and the problem was obvious. I knew it would be simple. After doing the GetAsync I had not cleared the HostFilename parameter. So the DirAsync still had this as a parameter. Thanks for all your input.

Re: [twsocket] ICS FTP Client
I had not cleared the HostFilename parameter. So the DirAsync still had this as a parameter. This is deliberate, the FTP command 'LIST directory' is valid, but not totally reliable with all FTP servers, it can save a lot of path commands. 'LIST filename' is also how to check if a specific file exists. The XDMLSD command supported by the ICS web server is the most efficient way of getting all directories in a single command.
