The one class that we do not want to delete should be easy to find It inherits from SoapHttpClientProtocol, should be the first class in the code file, and should have a name that ends with SyncService So, open Referencecs and look for the following line of code:

We delete all other classes and add the following using statement at the top of the file:

We do not need to add references to the MicrosoftSynchronization libraries, for the Configure Data Synchronization Wizard has already done that for us When it comes to dealing directly with Visual Studio, its templates, and its wizards, we are done What is left for us to do is write the functionality of our application We ll add just enough functionality so that we can walk through the following scenario 1 2 3 4 5 6 Synchronize data with the server Make some nonconflicting changes at the device and on the server Synchronize data with the server Make some conflicting changes at the device and on the server Synchronize data with the server After each synchronization, examine results, data, and errors

Using Barcode generator for .NET Control to generate, create DataMatrix image in VS .NET applications.
We begin by opening the form in design mode and then adding a fullscreen docked DataGrid control plus a two-entry menu to it, as shown in Figure 826 Then we turn to the form s code file We ll need to add the following: namespace declarations for synchronization, for our proxy classes, and for our typed data set; a routine to modify some customer rows; a routine to synchronize our changes with the server; and code to display the results of that synchronization We add the namespace declarations at the start of the code thusly:

In the form s Load event we create a typed data set and a table adapter for later use, like so:

To modify some data at the device, modifications that will then need to be synchronized with the server, we iterate through the rows of the

Listing 812 shows the routine for doing the synchronization of our changes with the server s data store, via the service It is well annotated Any class name that contains the word Cust was written by one of the wizards that we walked through Any class name that contains the word Sync, but not the word Cust, is defined in one of the MicrosoftSynchronization libraries that the project references

Listing 812: The Data Synchronization Routine
private SyncStatistics SyncCustomers() { SyncStatistics syncStats; try { // Create a proxy object for the synch service // Use it to create a generic proxy object ServerSyncProviderProxy prxCustSync = new ServerSyncProviderProxy( new CustCacheSyncService()); // Create the sync agent // for the Customer table // Assign the proxy object to it // Set it for bi-directional sync CustCacheSyncAgent syncAgent = new CustCacheSyncAgent();
Synchronizing Mobile Data
syncAgentRemoteProvider = prxCustSync; syncAgentCustomersSyncDirection = SyncDirectionBidirectional; // Sync changes with the server syncStats = syncAgentSynchronize(); // The above call to syncAgentSynchronize // retrieved all Customer table changes // that had were made at the server // between the previous call and this // call and placed them in our // SQL Server CE Northwind database here // on the device // We need to display that table to // our user We will use a data bound // data table to do so daptCustFill(dsetNorthwindCustomers); dgridCustomersDataSource = dsetNorthwindCustomers; } catch (Exception exSync) { MessageBoxShow(exSyncMessage); throw; } return syncStats; }
Note that the routine first creates a proxy object for our service and then uses that proxy object in the creation of another, more generic, proxy object Then the SyncAgent is created and is passed a reference to the generic proxy object Once any other SynchAgent properties have been set, the agent knows what needs to be synchronized and what service to use to do it The agent s Synchronize method then does the synchronization and returns the results in a SyncStats structure The SynchAgent object is the keystone object of data synchronization Although it is located on the device, you want to think of it as sitting between the server-side data store and the client-side SQL Server CE database Anything that your application needs to do at runtime to influence or alter the behavior of a synchronization will be done by invoking methods of, or setting properties of, or responding to events raised by the SynchAgent object or one of its contained objects For example, later in this demo we will need to obtain information about rows that failed to synchronize We will do that by handling an
