support bidirectional traffic, so a receiver can send information back to the sender over the same pipe it reads from. Listing 8-18 shows an Object Pascal implementation of the sender. Object Pascal makes direct Win32 calls to create and manipulate pipes. A C++ program would make exactly the same calls. I didn t use C# for this example, because the .NET Framework doesn t support traditional pipes. In their place, there is an entire infrastructure called the Remoting Framework that provides much more functionality, and in an object-oriented way. Listing 8-18. Using Object Pascal to Fire Events Using a Pipe type TSender = class private NotificationPipe: THandle; public constructor Create; destructor Destroy; override; procedure FireEvent; end; implementation constructor TSender.Create; const PipeName = '\\.\pipe\mynamedpipe'; AccessMode = PIPE_TYPE_MESSAGE or PIPE_READMODE_MESSAGE or PIPE_WAIT; MaxPipeInstances = 2; InBufferSize = 4096; OutBufferSize = 0; ClientTimeout = NMPWAIT_USE_DEFAULT_WAIT; NoSecurityAttributes = nil; begin NotificationPipe := CreateNamedPipe(PipeName, PIPE_ACCESS_OUTBOUND, AccessMode, MaxPipeInstances, OutBufferSize, InBufferSize, ClientTimeout, NoSecurityAttributes); end; destructor TSender.Destroy; begin CloseHandle(NotificationPipe); end; procedure TSender.FireEvent; var BytesWritten: Cardinal; Payload, ErrorMessage: String; Success: Boolean; begin if NotificationPipe = INVALID_HANDLE_VALUE then Exit; excel code 39 barcode font Descargar complemento de código de barras para Microsoft Word ...

You need to index tables only if you think your queries will be selecting a small portion of the table. If your query is retrieving rows that are greater than 10 or 15 percent of the total rows in the table, you may not need an index. Remember that using an index prevents a full table scan, so it is inherently a faster means to traverse a table s rows. However, each time you want to access a particular row in an indexed table, first Oracle has to look up the column referenced in your query in its index. From the index, Oracle obtains the ROWID of the row, which is the logical address of its location on disk. If you choose to enforce uniqueness of the rows in a table, you can use a primary index on that table. By definition, a column that serves as a primary index must be non-null and unique. In addition to the primary index, you can have several secondary indexes. For example, the attribute LAST_NAME may serve as a primary index. However, if most of your queries include the CITY column, you may choose to index the CITY column as well. Thus, the addition of secondary indexes would enhance query descargar code 39 para excel 2013 Install Code 39 Fonts Add-In in Excel - BarCodeWiz

Using the Code 39 Barcode Font. To generate a Code 39 barcode from a font, the data-to-encode is to be surrounded by asterisks as the start and stop characters, i.e. *153969*. In Microsoft Word, the start and stop characters should be "!" instead of the asterisk because of a formatting issue, i.e. !153969!. performance. However, a cost is associated with maintaining additional secondary indexes. In addition to the additional disk space needed for large secondary indexes, remember that all inserts and updates to the table require that the indexes also be updated. If your system involves a large number of inserts and deletes, understand that too many indexes may be detrimental, because each DML causes changes in both the table and its indexes. Therefore, an OLTP-oriented database ought to keep its indexes to a minimum. A data warehouse, on the other hand, can have a much larger number of indexes because there is no penalty to be paid. That s because the data warehouse is a purely query-oriented database, not a transactional database. Payload := 'Notification Payload'; Success := WriteFile(NotificationPipe, PChar(Payload)^, Length(Payload), BytesWritten, nil); if not Success then ErrorMessage := SysErrorMessage(GetLastError); end; end. The sender opens a write-only pipe using the Windows API method CreateNamedPipe. To fire an event, the sender writes to the pipe as if it were a file, using the Windows API method WriteFile. The Object Pascal receiver implementation is shown in Listing 8-19. Listing 8-19. Using Object Pascal to Receive Notifications over a Pipe type TReceiver = class private NotificationPipe: THandle; public constructor Create; destructor Destroy; override; procedure Run; procedure DoRun; function WaitForNotifications: String; procedure HandleEvent(ThePayload: String); end; implementation constructor TReceiver.Create; const PipeName = '\\.\pipe\mynamedpipe'; PipeAccess = GENERIC_READ; NoPipeSharing = 0; NoSecurityAttributes = nil; DefaultPipeAttributes = 0; NoTemplateFile = 0; begin NotificationPipe := CreateFile(PipeName, PipeAccess, NoPipeSharing, NoSecurityAttributes, OPEN_EXISTING, DefaultPipeAttributes, NoTemplateFile); end; destructor TReceiver.Destroy; begin CloseHandle(NotificationPipe); end; procedure TReceiver.Run; begin while NotificationPipe <> INVALID_HANDLE_VALUE do DoRun; end; code 39 excel macro Free Code 39 Barcode Font Download - Fonts
