OnQueryCompositeInstancesStarting Method (StorageDbDataAccessAgent)
Summary
Raises the QueryCompositeInstancesStarting event.
Syntax
protected virtual void OnQueryCompositeInstancesStarting(QueryCompositeInstancesArgs e)
Protected Overridable Sub OnQueryCompositeInstancesStarting(ByVal e As QueryCompositeInstancesArgs)
protected:virtual void OnQueryCompositeInstancesStarting(QueryCompositeInstancesArgs^ e)
Parameters
e
An QueryCompositeInstancesArgs that contains the event data.
Remarks
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.
