SqlCeReplication Class

Initializes a new instance of the SqlCeReplication object. For more information about SQL Server replication, see the SQL Server 2005 Books Online. For more information about merge replication with SQL Server Compact Edition, see the SQL Server Compact Edition Books Online.

Remarks

SQL Server Compact Edition 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 Edition. SQL Server Compact Edition is optimized for use as an embedded database within applications. Using SQL Server Compact Edition 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 2005, including SQL Server 2005 Express Edition, are optimized to serve as a database for Web sites.

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

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

Example

The following example shows how to synchronize data between a Microsoft SQL Server 2005 Compact Edition 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.

Dim repl As SqlCeReplication = Nothing

Try
    ' Instantiate and configure SqlCeReplication object
    '
    repl = New SqlCeReplication()
    repl.InternetUrl = "https://www.adventure-works.com/sqlmobile/sqlcesa30.dll"
    repl.InternetLogin = "MyInternetLogin"
    repl.InternetPassword = "<password>"
    repl.Publisher = "MyPublisher"
    repl.PublisherDatabase = "MyPublisherDatabase"
    repl.PublisherLogin = "MyPublisherLogin"
    repl.PublisherPassword = "<password>"
    repl.Publication = "MyPublication"
    repl.Subscriber = "MySubscriber"
    repl.SubscriberConnectionString = "Data Source=MyDatabase.sdf"

    ' Create the local SQL Mobile Database subscription
    '
    repl.AddSubscription(AddOption.CreateDatabase)

    ' Synchronize to the SQL Server to populate the Subscription 
    '
    repl.Synchronize()
Catch
    ' Handle errors here
    '
Finally
    ' Dispose the repl object
    '
    repl.Dispose()
End Try

SqlCeReplication repl = null;

try
{
    // Instantiate and configure SqlCeReplication object
    //
    repl = new SqlCeReplication();
    repl.InternetUrl = "https://www.adventure-works.com/sqlmobile/sqlcesa30.dll";
    repl.InternetLogin = "MyInternetLogin";
    repl.InternetPassword = "<password>";
    repl.Publisher = "MyPublisher";
    repl.PublisherDatabase = "MyPublisherDatabase";
    repl.PublisherLogin = "MyPublisherLogin";
    repl.PublisherPassword = "<password>";
    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();
}
