Procedure for stream detection

A stream is associated with the "Connection request of new stream" event. This event is run when a request to connect to an incoming stream is detected.
This event is run in one of the following cases:
  • if the Detection property applied to the stream is set to True.
  • if the option "Detection of active incoming streams" has been checked in the stream description window.
Remark: This event is run in a specific thread of WLanguage. Therefore, it is subject to limitations specific to the threads. For more details on threads, see Managing threads with WINDEV.
