This article shows the fine points of taking advantage of the Windows Overlapped API for asynchronous communication through named pipes. The greatest achievement of this code compared to other similar ones is that the server and client actually stop when you tell them to.

PipeListenner

Dim WithEvents Listenner As New _
    NamedPipes.PipeListener("myPipe")
Listenner.StartListenning

Private Sub Listenner_ClientConnected(ByVal sender As Object, _
        ByVal e As NamedPipes.ClientConnectedEventArgs) _
        Handles P.ClientConnected
    e.ClientStream.Read
    e.CleintStream.Write
    ...
End Sub

PipeClient

Dim Client As New NamedPipes.PipeClient("\\.\pipe\myPipe")
Client.Connect
Client.ClientStream.Read
Client.ClientStream.Write
    ...
