Named-pipe Error: Unable to create named pipe w/err 0x0000007b



Unable to create named pipe w/err 0x0000007b


I am getting the above error when I try to connect the server and client on different machines.


The code I got from MSDN Link: http://code.msdn.microsoft.com/windowsdesktop/CppNamedPipeCommunication-7447a0bf


I am using Windows 7 machines to communicate.


#define FULL_PIPE_NAME L".pipeSamplePipe"


To communicate with different machines I changed the above line to:


#define FULL_PIPE_NAME L"My Machine's IP addresspipeSamplePipe"


Note: In the same machine itself, it will work only if the path is : L"

how to write to a named pipe and don't wait for reading the pipe
Programming Languages

i'm writing to a pipe until user enters the string "end". if the user enters the string "end", i suppose to go further. here I've to close the pipe and print the message "After Written to Pipe". But its not printing the line "After Written to Pipe" even i entered "end" string. How can i close the pipe and go further even-though there is no process to read the pipe?..


Hi here is my code.,


int main() {
int fd;
char *b, *c;
printf("Enter Str : ");
b = malloc(50);
gets(b);
while(strcmp(b,"end")!=0){
if(access("MSG",F_OK) != -1) // check pipe is already available.
{
fd =

Read from a named pipe in bash and pipe it into a java process
Programming Languages

I have a JAVA-Jar-File which is provided by a third-party-dev.
The File reads from STDIN and writes to STDOUT.


I was able to configure the JAR-File to write to a log file instead.


But I also have to rewrite the input-source from STDIN to a named pipe, so I can send commands to the java-pocess via my own application.


I already tried this two things to read from the pipeline (bash):


cat < pipeline_name | java -jar external_application.jar

This works fine for the first command. After receiving the first input line, the 'cat' terminates and I am not able so send commands a

controlling the name of a named pipe when hosting WCF net.pipe binding in IIS
Programming Languages

I have a service accessible via http and net.pipe. It is being hosted in IIS 7 (Server 2008). I may be hosting different instances of this service for several customers on the same machine and hence the HTTP is setup with virtual hostnames etc. This is all working fine.


I thought I would do similar for the net named pipe binding - using some form of
the customers 'virtualhostname' in the named pipe base address, therefore allowing me
to access the different customer instances with different net.pipe urns (I realize
the net.pipe names are URN's not URL's so they can be essentially arbitrary but
I thought I would follow a similar pattern to the HT

How can I have output from one named pipe fed back into another named pipe?
Programming Languages

I'm adding some custom logging functionality to a bash script, and can't figure out why it won't take the output from one named pipe and feed it back into another named pipe.


Here is a basic version of the script (http://pastebin.com/RMt1FYPc):


#!/bin/bash
PROGNAME=$(basename $(readlink -f $0))
LOG="$PROGNAME.log"
PIPE_LOG="$PROGNAME-$$-log"
PIPE_ECHO="$PROGNAME-$$-echo"
# program output to log file and optionally echo to screen (if $1 is "-e")
log () {
if [ "$1" = '-e' ]; then
shift
$@ > $PIPE_ECHO 2>&1
else
$@ > $PIPE_LOG 2>&1
WCF named pipe client notification/detection of pipe state change
Programming Languages

I have two .NET C# windows forms applications that are communicating with each other via WCF named pipes. One of the applications is hosting a WCF service and the other is the client. Communication is working fine, the client can call service methods and callbacks work fine, etc. However, one issue I am having is if the host application shuts down, the client is not able to detect that the pipe is no longer available. I have tried registering event handlers on the pipe for all events (Closing, Closed, Faulted), but these never get called when the host application shuts down. Also, if I try to check the pipe state in the client with the pipe.State property, I get back a state of Opene
