OnQueryCompositeInstancesStarting Method

Raises the QueryCompositeInstancesStarting event.

Syntax

Visual Basic
C#
Objective-C
Java
C++

protected virtual void OnQueryCompositeInstancesStarting( 
   QueryCompositeInstancesArgs e
)

'Declaration
 
Protected Overridable Sub OnQueryCompositeInstancesStarting( _
   ByVal e As QueryCompositeInstancesArgs _
)

'Usage
 
Dim instance As StorageDbDataAccessAgent
Dim e As QueryCompositeInstancesArgs
 
instance.OnQueryCompositeInstancesStarting(e)

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.
