SqlCeReplication Class

Initializes a new instance of the SqlCeReplication object. For more information about SQL Server replication, see the SQL Server Books Online. For more information about merge replication with SQL Server Compact 3.5 SP1, see the SQL Server Compact 3.5 SP1 Books Online.

Namespace: System.Data.SqlServerCe
Assembly: System.Data.SqlServerCe (in system.data.sqlserverce.dll)

SQL Server Compact 3.5 SP1 is not currently optimized to serve as a database for Web sites. By default, connections from ASP.NET-connected applications are blocked in SQL Server Compact 3.5 SP1. SQL Server Compact 3.5 SP1 is optimized for use as an embedded database within applications. Using SQL Server Compact 3.5 SP1 as a database for Web sites requires support for multiple users and concurrent data changes. This can cause performance problems. Therefore, these scenarios are not supported. Other editions of SQL Server, including SQL Server 2005 Express Edition and later versions, are optimized to serve as a database for Web sites.

SQL Server Compact 3.5 SP1 can be used with ASP.NET in application scenarios where ASP.NET is used to create SQL Server Compact 3.5 SP1 databases for synchronization scenarios. Use the following code to change the default behavior of SQL Server Compact 3.5 SP1 to work within ASP.NET.

AppDomain.CurrentDomain.SetData("SQLServerCompactEditionUnderWebHosting", true)


System.Object
  System.Data.SqlServerCe.SqlCeReplication

The following example shows how to synchronize data between a SQL Server Compact 3.5 SP1 Subscriber and a SQL Server Publisher. A SqlCeReplication object is created, numerous properties of the SqlCeReplication object are set, and then the Synchronize method is called.

SqlCeReplication repl = null;

try
{
    // Instantiate and configure SqlCeReplication object
    //
    //NOTE: when possible, prompt users to enter security 
    //credentials at runtime. If you store credentials in a file, 
    //you must secure the file to prevent unauthorized access.
    //
    repl = new SqlCeReplication();
    repl.InternetUrl = "http://www.adventure-works.com/sqlce/sqlcesa35.dll";
    repl.InternetLogin = "MyInternetLogin";
    repl.InternetPassword = "<enterStrongPassword>";
    repl.Publisher = "MyPublisher";
    repl.PublisherDatabase = "MyPublisherDatabase";
    repl.PublisherLogin = "MyPublisherLogin";
    repl.PublisherPassword = "<enterStrongPassword>";
    repl.Publication = "MyPublication";
    repl.Subscriber = "MySubscriber";
    repl.SubscriberConnectionString = "Data Source=MyDatabase.sdf";

    // Create a local SQL Mobile Database subscription
    //
    repl.AddSubscription(AddOption.CreateDatabase);

    // Synchronize to the SQL Server database
    //
    repl.Synchronize();
}
catch (SqlCeException)
{
    // Handle errors here
    //
}
finally
{
    // Dispose the repl object
    //
    repl.Dispose();
}
