Raises the QueryCompositeInstancesStarting event.
Protected Overridable Sub OnQueryCompositeInstancesStarting(
ByVal e As QueryCompositeInstancesArgs
An QueryCompositeInstancesArgs that contains the event data.
Raising an event invokes the event handler through a delegate. The OnQueryCompositeInstancesStarting method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class. Notes to Inheritors: When overriding OnQueryCompositeInstancesStarting in a derived class, be sure to call the base class's OnQueryCompositeInstancesStarting method so that registered delegates receive the event.
