    ' returns one error in the collection
    '
    repl.Synchronize()
Catch e As SqlCeException
    Dim err As SqlCeError
    For Each err In e.Errors
        ' Use SqlCeError properties if you need specific
        ' application logic depending on the error condition
        '
        If 28577 = [err].NativeError Then 'SSCE_M_SCHEMAHASCHANGED
            ' Error specific logic goes here...
            '
        End If

        ' Note: For native error numbers, refer to SQL Server Mobile Errors
        ' in the SQL Server Mobile Books Online

    Next err
End Try

try
{

    // SqlCeReplication may throw SqlCeException which contains a 
    // collection of errors; SQL Mobile database engine always

catch (SqlCeException e)

    foreach (SqlCeError error in e.Errors)
