Hi all. I'm developing a FTP server using Indy FTP Server. I want to do sth on the server as soon as the file uploading is finished. How can I capture this event?

There currently is no event available for that.  The only option is to
derive your own TStream class, instantiate it in the OnStoreFile event,
track what you need to while the file is being streamed, and then finally do
what you need to when the stream is being destroyed.

I think I may get a solution. There is a property "DataChannelThread" in TIdFTPServerThread, and I can handle its OnStopped. I tried and it seemed OK. :-)

The only problem with that approach is that you won't be told why the thread
is being stopped.  It could be for a successful transfer, but then again it
could also be for a failed transfer, as well as an aborted transfer.  There
is simply no way for your even handler to know which situation is actually
the case.

Also, that approach can only be applied to Indy 9.  Starting with Indy 10,
TIdFTPServer does not use separate threads to perform transfers anymore.
