'Declaration
 
Overloads Sub BeginUpdate( _

   ByVal events As FileSystemEvents, _

   ByVal userData As Object _

) 

'Usage
 
Dim instance As IBatchUpdateable

Dim events As FileSystemEvents

Dim userData As Object

 

instance.BeginUpdate(events, userData)

void BeginUpdate( 

   FileSystemEvents events,

   object userData

)

Parameters

events

A FileSystemEvents object that will be used to raise events. Cannot be a null reference (Nothing in Visual Basic).

userData

Opaque data that will be passed back to the event handler when an event is raised.

A call to BeingUpdate must be accompanied by a subsequent call to EndUpdate, or desynchronization can occur. One mean of making sure that both calls stay synchronized is to use a finally block:

try 

{

  i.BeginUpdate();

  // Do some modifications to the folder

}

finally 

{

  i.EndUpdate();

}

In C#, the preferred way is to use the AutoBatchUpdate class in a using statement.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
