[DUG] Indy Sockets - How to Receive Asynchronously

[Ross Levis]

I would be interested as well as I currently use Indy to connect to an FTP
server, upload a fil,e and disconnect roughly every 4 minutes.  I do this in
a thread with every possible exception taken care of, but for some users,
the PUT procedure hangs occasionally and never returns, even with timeout
settings, and it seems to occur when the internet is slow and unreliable.

 

I have had to resort to code which checks if the thread is taking too long
and then freeing the TIdFTP instance from my main thread and forcefully
terminating it, and starting another one.

 

Ross.

Hi Paul,

 

May I ask if ICS can handle un reliable interterm connection robust enough?
i.e. FTP connection drop frequently etc

 

TIA

 

Have a nice day

 

Regards

Leigh

Yes, I am.

I write all my servers and client software with it.

It's very stable and fast

V7 works with D2009 with lot's of demo's

 

If you have questions, subscribe to the twsocket list (twsocket at elists.org)

You'll get good support there

 

Indy isn't bad either, but blocking only.

With ICS, a server can handle hundreds of connections in a single thread and
very fast.

 

Paul
