Comentários

Um sinalizador é marcado na tabela do sistema de assinaturas do SQL Server Compact 3.5 para indicar que, durante a próxima sincronização, a assinatura deverá ser reinicializada. Depois de chamar o método ReinitializeSubscription, o aplicativo deve chamar o método Synchronize para excluir a réplica existente e baixar uma nova réplica publicação para o dispositivo baseado no Windows Mobile.

Exemplos

Dim repl As SqlCeReplication = Nothing

Try
    ' Create SqlCeReplication instance
    '
    '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/sqlmobile/sqlcesa35.dll"
    repl.InternetLogin = "MyInternetLogin"
    repl.InternetPassword = "<enterStrongPassword>"
    repl.Publisher = "MyPublisher"
