Remarks

 is not currently optimized to serve as a database for Web sites. By default, connections from -connected applications are blocked in . is optimized for use as an embedded database within applications. Using 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 , including and later versions, are optimized to serve as a database for Web sites.

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

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

Examples

The following example shows how to synchronize data between a Subscriber and a 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
    '
    '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 = "https://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 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
    //
    //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 = "https://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();
