When working with the RTC SDK (especially when using its default message-driven asynchronous sockets API), you should
NEVER
use
Application.ProcessMessages
,
ShowMessage
,
ShowModal
(or any other function or method which would allow messages from the OS to be processed while waiting) from any event triggered by RTC components.
If you ignore this rule, you are likely to end up with
Access Violations
and other kinds of Exceptions raised after your event returns back to the component, or while waiting and trying to use the component from inside the event, because RTC components are being dinamically created and
destroyed
based on messages
received from the OS.
