Hi all, firstly thanks again to all that has assisted me this
year it has been good. And for those who are down and out
I really wish you a great day today and that things
get better and better in the following year (honestly)!

Anyway I have a thread that is doing some Indy stuff.
First it connects then does what it has to do until
I terminate the thread.

Thing is I am doing testing with an invalid I.P. address
and want the connection to fail (no problem) also
the Connect() command may take a few seconds (5 to 10)
before it fails.

But within say 1-2 seconds I may change my mind and want
to close the thread, but this is in te middle of the Connect
method.

So the problem is how do I 'intercept' the Connect() method
while it is trying hard to connect to an invalid address
so that I can quickly exit my thread.
e.g. force time out the Connect method.

Thanks again!!!
And have a great new year!!

That is normal for TCP.  It can take awhile for a host to be detected
as invalid if it canot be reached right away.

You can disconnect the socket from within a different thread (such as
the thread that wants to terminate the worker thread), which will
cause Connect() to fail immediately within the worker thread that
called it.
