Re: [twsocket] FTP client and windows service problem
Maybe you have a file permission problem. Your service is logged under system account or another account. Check that it has the required permissions. Also a side problem I'm having is: do you know of a simple way to parse the results from the DIR command into a simple list of filenames, sizes, There is source code available at http://www.smatters.com/ics/. Rather old but still working. -- [EMAIL PROTECTED] http://www.overbyte.be - Original Message - From: Nikolay Simeonov [EMAIL PROTECTED] To: twsocket@elists.org Sent: Tuesday, April 26, 2005 1:44 AM Subject: [twsocket] FTP client and windows service problem Hello Francois, I'm writing a service and when I try to get the directory FTP1.Dir returns false.

I've just found something interisting here: http://www.ictrnid.org.uk/downloads/SIP/SIP-0.3.zip The stack uses Indy 9.0.14 :( why not ICS?

RE: [twsocket] FTP client and windows service problem
Hi Arno, I did use any possible way that occurred to my mind to figure out what the problem is without any success. And as I said - it's working just fine when I am testing it from a standart windows application, but when I start the service it's crashing. What I was getting from the DIR command is that it couldn't save the file. I also tried generating a random file name for the directory listing and it didn't help either. Is there another way to capture the directory listing without saving it to a file? I've downloaded a unit named ftpcommon.pas somewhere that helps parsing a lot, but I can't find the link at the moment:( If you can send me a copy ot this unit I would be eternally thankful to you :) Send it to my first name@my last name.net (not .com) Best Regards, Nikolay Simeonov -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Arno Garrels Sent: Tuesday, April 26, 2005 10:14 AM To: ICS support mailing Subject: Re: [twsocket] FTP client and windows service problem Nikolay Simeonov wrote: Hello Francois, I'm writing a service and when I try to get the directory FTP1.Dir returns false.

It definitely has the permissions because I ran it as an administrator.

RE: [twsocket] FTP client and windows service problem
But in this case FTPclient1.Dir would return true and in my case it's returning false. However no exception is thrown and I'm lost how to figure out WHY I'm getting false there and what the problem could be. Everything is working just fine as Windows Application - it's getting the folder listing, downloading the files etc., but when I use the same unit in a Service I'm getting false when I call the DIR function.

[twsocket] installation of ICS with BCB6.0
Perhaps a well known problem : I try to install ICS with BCB6.0 - Building of IcsBcb60.bpk is ok (no error) - Just after, i get a window stating that the following modification is mandatory : Add bcbie (Bcbie has the explicit unit Shdocvw_ocx)= It seems that the only choice i have is to push ok. - Then, i install IcsBcb60.bpl just produced above, and i get the message Cannot load IcsBcb60.bpl because it has the unit Shdocvw_ocx which is already in bcbie60. - If i uninstall bcbie60.bpl, i can then install IcsBcb60.bpl but it does not work properly.

[twsocket] [HELP] FtpServer : Long Process HOWTO
Hi everyone, here's my problem : still in my video server, i'm using the FtpServer component to download a set of images, taken from a camera, through one simple RETR call. On the OnGetProcessing event, i retrieve from a DB (the connection has already been made) all the images needed (range of images provided in the filename which is formatted) and push them into the Client.Datastream. for the algorithm, i have no problem. but what happens if several ftp client asks at the same time for a big amount of images (average : 1 image = 21Ko) let's say 1200 images ? Is Each OnGetProcessingEvent fired one after anoher ? which would then result in a queueing of each request... thanks for your help !
