Purpose

SessionPropertyChanged event is fired to notify a change to a parent session property made by a child session.
 

Syntax

Operation

ParamMap PROIV Interface Map containing the parameters passed from the event producer.

hSessionID ID of the session that made the change.

nResourceID ID of the changed property.

Remarks

A call may be made to GetPropertyValue using the supplied resource ID and setting Session Handle to the value 2 to fetch the changed value. An acknowledgement may be sent to the session that raised the event by making a call to SetPropertyValue using the supplied session ID as the session handle. The resource ID and the value passed may be developer defined.

Care must be taken when calling SetPropertyValue from this event handler to ensure that a recursive event sequence is not created. This occurs if the parent session or a value of 2 is used for the call instead of the supplied hSessionID parameter.
