Hello all
First of all, I would like to congratulate the ICS team for the wonderful
job in creating a way to share windows handles for processing messages.
I´m now extensively using this mechanism in all our application.
One question though, why is the default limit of 100 messages

I currently use D2010 but I plan to migrate to XE2 soon
Anyway, D2010 already implements unicode and generics, so, supporting from
2010 to XE2 is a good option

Does this means that the new ICS works in MACOS?

If the reason that you call the Flush method is because you want to be

Yes, thats it, it is something like this

Hello all,
I want to discuss an architectural issue here
I´m debugging an application of mine and yesterday it has stopped working and I
got the following EurekaLog call stak information
|00507C4D|Servidor.exe|OverByteICSWSocket.pas|TCustomWSocket
|RaiseException
Éric,
Since ICS works asynchronous a reconnect-timer should be started from
event handler OnSessionClosed, is that the case?
Also the best place to destroy the object is from OnSessionClosed as
well.
But the OnSessionClosed event will be triggered if I try to connect to an
inacessible
You have to call Abort once Connect has been called and OnSessionClosed
has not been triggered yet to abort the session. Then in OnSessionClosed
start the timer or post a custom message if you want to reconnect at once.
Ok, now I undestood, I will try to implement on that way
Thank you Arno!
