'Usage
 
Dim instance As ZipArchive
Dim events As FileSystemEvents
Dim userData As Object
 
instance.BeginUpdate(events, userData)

public void BeginUpdate( 
   FileSystemEvents events,
   object userData
)

Parameters

events

A Xceed.FileSystem.FileSystemEvents object that will be used to raise events. Cannot be NULL.

userData

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

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

try 
{
  i.BeginUpdate();
  // Do some modifications to the zip file
}
finally 
{
  i.EndUpdate();
}

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