Redirect IO der Prozess Windows socket

Ich bin neu winsock, versuchte ich zu schreiben, einen server-socket, nimmt neue Verbindung, dann ruft es eine externe ausführbare Datei. Wie können wir die Umleitung von stdin und stdout der externen ausführbaren Datei an den client-socket angenommen. Ich gegoogelt und fand den folgenden code, aber es funktioniert nicht. Der neue Prozess wurde erfolgreich erstellt, aber der Kunde konnte nicht empfangen auch keine Daten aus dem neuen Verfahren. Ich bin mit Windows 7 und Visual Studio 2008 Express edition. Jeder hilft und die Kommentare werden geschätzt. Vielen Dank, sehr viel!
