OnNodeConnChangeEvent
Summary This event is generated whenever a connection is created or
modified, or whenever the ConnectDescTemplate used by a
connection is modified.
You can enable this event with the
BeginNodeConnChangeEvent method. You can disable this
event with the EndNodeConnChangeEvent method.
Once you have enabled this event, it will be fired whenever
an application invokes the Connect method to create or
modify a connection, or whenever an application invokes the
Disconnect method to remove a connection. It will also be
fired whenever the ConnectDescTemplate used by a
connection is modified.
When adding a new connection or removing a connection,
this event will be genereated once for the connection’s hub,
and once for each target that has been added to the
connection. When adding or removing a subset of targets
from a connection, this event will be generated once for each
of the affected targets. When this event is generated for a
connection hub, the value of the TargetDeviceHandle element
will match the value of the hubDeviceHandle element, and
the value of the TargetNvMtIndex element will match the
value of the HubNvMtIndex element.
