Enumerate named pipes?

Is there any way of listing the named pipes that are open on any given system?

Thanks in advance,
Duncan

I've asked this on every forum and on the public.microsoft.vb newsgroups with no success - surely this must be possible?

I barely understand your questions, so maybe the following is an out of topic suggestion; however, it seems as if Vbnet knows something...

Have you tried here?

(and search for "pipes")

No help in this particular case, but a very useful site to add to my bookmarks...

(and do not forget to give us solution to named pipes as soon as you find it. Btw, add a small description of what named pipes are: I will learn something more!);)

A named pipe is an inter-process communication method.

To connect to an existing named pipe (or create a new one) you call CreatenamedPipe


Declare Function CreateNamedPipe Lib "kernel32" Alias "CreateNamedPipeA" (byval lpName as string, & _
byval dwOpenMode as Long, byval dwPipeMode as Long, byval nMaxInstances as Long, byval nOutBufferSize as Long, & _
byval nInBufferSize as Long, byval nDefaultTimeOut as Long, lpSecurityAttributes as SECURITY_ATTRIBUTES) as Long




Typically a pipe's name would be \\.\pipe\pipename but you can connect to a named pipe on another machine if you put the name in the format \\servername\pipe\pipename

Once you have a pipe handle you can read and write to it to basically "talk" through the pipe.

This makes it very handy for inter process communication.

HTH,
Duncan
