Help with named pipes

Hi,

I start a named pipe in a server process:

pipe = CreateNamedPipe("\\\\.\\pipe\\Test", PIPE_ACCESS_DUPLEX | FILE_FLAG_WRITE_THROUGH, PIPE_TYPE_BYTE, PIPE_UNLIMITED_INSTANCES, 1000, 1000, 3000, NULL);


and use it in a client with:


pipe = CreateFile( "\\\\.\\pipe\\Test", GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);
WriteFile(pipe, buffer, 7, (DWORD*)&y, NULL);
CloseHandle(pipe);

I receive the data on the server side but the problem is that i cannot open the pipe from the client again. I always get an error.

Is there something that I am missing ?

I really appreciate any help on this.

Well...what error?

• A SDK function (e.g. CreateDirectory) failed. What I'm doing wrong?

Are you doing the CreateFile(...) again?

Is there a reason why you're closing the pipe immediately after doing the Write??

iam comparing various IPC mechanisms.wanted to know whether named pipes,mail slots,RPCs and Sockets are secure or not.Can anybody help me???
