Hi!

How can i detect if there are any active users on the server...like if
they are downloading something?

I want to turn of my server but how do i know that there aren anyone
downloading or something?

Can i see if any Tstreams are active...or maybe count the
usersLogins-disconnects=users left on server?

How can i be sure that when turning of the server i will not abort
somone downloading something?

Thanx in advance
Frankie

The same way you do with any other Indy TCP-based server - check the
server's Threads (Indy 9) or Contexts (Indy 10) list.


TIdFTPServer does not keep track of that information. You have to
keep track of that in your own code.


You have to track that yourself.


The server does keep track of that much for you.

And where do i find this list?


You mean i have to rewrite the Tstream class?


They do? Is there a value or something i can read from? Or is is the
Contexts List you where talking about earlier in this post?

It is a propety of TIdTCPServer. Please read the documentation.


That is part of it, as that is the only way to detect when a transfer
is finished. You will have to set up your own list of download
information, and then use the OnStoreFile and OnRetreiveFile events,
and the TStream destructor, to keep that list up-to-date.


Again, please read the documentation. In the Threads (Indy 9) or
Contexts (Indy 10) list, the server holds TIdFTPServerThread (Indy 9)
or TIdFTPServerContext (Indy 10) object instances, one for each
client. That will tell you how many clients are connected, and they
have a UserName property available, so you will know who is logged in.

Yeah, i read the docs...and it not easy when it says "Topic will be
explalined later" or something like that.

It isn easy to learn Indy when the demos absolutely suck 2....they are
more then 3 years old.

Why don you just tell me what property i should look for? I found:
FtpServer.Context but there are no User information there...all i got is
a locklist property/method

/Hope you understand my frusrtation...if you don i am willing to
explalin it more

I already have. Please re-read my earlier replies again more
carefully.


Then you did not pay attention to what I actually told you. I will
say it again:

TIdFTPServerContext ...
clients

For example:

uses
IdObjs;

var
List: TIdList;
I: Integer;
Ctx: TIdFTPServerContext;
begin
List := IdFTPServer1.Contexts.LockList;
try
for I := 0 to List.Count-1 do
begin
Ctx := TIdFTPServerContext(List[I]);
ShowMessage(Ctx.Username);
end;
finally
IdFTPServer1.Contexts.UnlockList;
end;
end;
