SyncAgent Class

Synchronization Services - ADO.NET 1.0 SP1

The SyncAgent object orchestrates synchronization.

Namespace: Microsoft.Synchronization
Assembly: Microsoft.Synchronization.Data (in microsoft.synchronization.data.dll)

'Declaration
Public Class SyncAgent
	Implements IDisposable
'Usage
Dim instance As SyncAgent

public class SyncAgent implements IDisposable
public class SyncAgent implements IDisposable

The SyncAgent loops through each of the tables to be synchronized and calls the client synchronization provider to retrieve and apply changes at the client database. Then it calls the server synchronization provider to retrieve and apply changes at the server database.

The following code example creates a class that derives from SyncAgent. The class instantiates a client synchronization provider and a server synchronization provider, creates a synchronization group, and adds the Customer table. When adding the table, synchronization direction and a table creation option are also specified. To view this code in the context of a complete example, see How to: Exchange Bidirectional Incremental Data Changes Between a Client and Server.

        'Instantiate a server synchronization provider and specify it
        'as the remote provider for this synchronization agent.
        Me.RemoteProvider = New SampleServerSyncProvider()

        'Create a Customer SyncGroup. This is not required
        'for the single table we are synchronizing; it is typically
        'used so that changes to multiple related tables are 
        'synchronized at the same time.

        'Add the Customer table: specify a synchronization direction of
        'Bidirectional, and that an existing table should be dropped.
