Pipes in Windows NT

Would anyone be able to tell me whether it's possible to create a named pipe from Java program under Windows NT? Or read from a named pipe created by a VisualBasic or C++ program in WinNT?

I've been using named pipes from Java under W2K. I suppose there should work on NT.
I open the pipe as any other file, this time called \pipe\yourname. You can prefix it with a server name. The Windows file system takes care of the rest.

Any way to disable the video preview/PIP window?

I would like to be able to disable the PIP/preview window during a chat...don't see any obvious way to do this...
can I?
Thanks

Consequently if you have a MAc account on two
computers and use the same full name in the Address
Book you will have problems.
There is also a secondary issue if the comptuers have
the same name.
hey Ralph-
yeah, I could understand that, but the 2 machines do NOT have the same name, and I've set up different address book entries...one doesn't have ANY accounts active...raw machine that I just want to get the Bonjour chatting to work...
interestingly, it works MUCH better on a computer to computer network than it does with the 2 machines just accessing a Airport express that is NOT connected to the internet.

Getting FMS to broadcast a media file being read via a named pipe.

I know you can broadcast partial AVI videos due to it's format. What I want to do, is feed an avi file to fms which is being generated by software on the local machine. If I create a named-pipe(on windows), will I be able to feed an avi file to fms while it's being read?

Thanks Balusc!!
I have made use of your code to display PDF files in an IFRAME tag too!!! I just dint believe that this would be possible. Please just take a look at my JSP page.

Named pipes?

Hi everyone,
Anyone knows how to implement a full named pipe using java?
i am wondering if it is possible to implement a named pipe in windows xp using .net which could "communicate" with a java app.
Many thanks,

Hi everyone,
here is where i am stuck in:
after reading the article i have a couple of questions:
how can the command mkfifo in java be implemented?
Besides, what i have done is as follows:
i have an app which is using the runtime to create another process in order to receive all the messages from some libraries. For the moment it is receiving all the messages and copying them into a file (this part works perfectly)
<Master Code>
FileOutputStream fos = new FileOutputStream("text.txt");//args[0]);
Runtime rt = Runtime.getRuntime();
//Process pipe = rt.exec("mkfifo pipe");
Process proc = rt.exec("java MainInterface");
StreamGobbler outputGobbler = new
StreamGobbler(proc.getInputStream(), "OUTPUT", fos);
// kick them off
outputGobbler.start();
<end Master Code>
<Thread which copyes into a file>
class StreamGobbler extends Thread
InputStream is;
String type;
OutputStream os;
StreamGobbler(InputStream is, String type, OutputStream redirect)
this.is = is;
this.type = type;
this.os = redirect;
public void run()
try
PrintWriter pw = null;
if (os != null)
pw = new PrintWriter(os);
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line=null;
while ( (line = br.readLine()) != null)
if (pw != null)
pw.println(line);
System.out.println(type + ">" + line);
pw.flush();
if (pw != null)
pw.flush();
} catch (IOException ioe)
ioe.printStackTrace();
<End Thread which copyes into a file>
And the app called by this master program, which should show the messages incoming in the pip in a text area:
<mainInterface>
public static void main(String[] args) throws IOException{
javax.swing.SwingUtilities.invokeLater(new Runnable() {
//Here should be the pipe called
public void run() {
createAndShowGUI();
<End mainInterface>
Now the point is how can be done to write instead in a file, into a pipe which the mainInterface could access
Many thanks

Reading / writing to named pipes in java created by C under WinNT

Hi,
i just wanted to know if im somehow able to read/write to a named pipe under WinNT. I've created a named pipe, but i cant seem to access it under java.
i tryed
File pipe = new File("\\\\.\\pipe\\myPipe");
but when i do pipe.exists() it returns false..
When i try to access this very same pipe from C it works like charm, but not from java.. Im 100% sure that the pipe exists, i have a tool that lists me all open pipes under windows and my pipe is listed there too.
I even tryed to use RandomAccessFile, but it just throws a FileNotFoundException..
Anyone was ever able to sucessfully read/write from named pipes in java under WinNT (any windoze ?)
Thanks

Thanks, but i always get a Pipe not found error (FileNotFoundException), im 100% sure the pipe exists, my .dll can write to it and read from it, im using the pipelist tool from http://www.sysinternals.com/ntw2k/info/tips.shtml#NamedPipes to list me all the pipes current open under WinNT - and my pipe is there...
My dll creates the pipe, here is the code :
g_hPipe = CreateNamedPipe(
lptstrPipeName , // name of pipe
//FILE_FLAG_OVERLAPPED |
PIPE_ACCESS_INBOUND, // pipe open mode
PIPE_TYPE_BYTE|
PIPE_READMODE_BYTE |
PIPE_WAIT, // pipe IO type
1,// number of instances
0, // size of outbuf (0 == allocate as necessary)
0, // size of inbuf
1000, // default time-out value
&sa); // security attributes WARNING: passing null
// all clients have the same security rights as the server
Is your CreateNamedPipe any different ? Or does it maybe only work under Win2k ? AFAIK named pipes under windows are not accessable through the file system.
Thanks again for your reply

Can't start mysql

when I type "rc.d start mysqld" it displays busy for a while, then fails. At this point it does not generate an error message. I have changed the permissions of /var/lib/mysql recursively to 777. I have also created the mysqld directory in /var/run and given it 777 permissions. I hope I have included all the relevant files.
I have read every suggestion on the internet and gotten nowhere. Please help a noobus out. Thanks in advance.

Hi,
I seem to have had an issue with mysql as well and it appears to be that I don't have a sock file as I have checked /var/run/mysqld for mysqld.sock and it does not exist so would that be what is stopping mysql server from starting and if so how do I create the sock file ??
Cheers
Quazza
Update - Actually I solved my problem to, it was to do with my log files filling up but that also led to the bigger problem of a failing HD oh what fun anyway got there before any major data loss.

Thread to read from external program

Hello Fellows,
Here it is, I'm trying to interact with other programs using Labview 8.0.
I have read lots of messages on Active X and threads to understand a bit on that functionnalities and can't figure out if I could or not do my program.
So image explains better than words, please look at the attached file to see my issue.
Other question is about the the Open System Command Pipe.vi, read From Pipe.vi, Close Pipe.vi etc. Are these vi's able to create a vrtual COM port as a pipe ?
And is this Vis available in LabVIEW 8.0 Full Dev ?
Thanks for your reply....see you

Hi
The Open System Command Pipe.vi, read From Pipe.vi, Close Pipe.vi etc are in Labview full but only linux and MAC OS version. You can not use pipe with Windows.

Shell cmd to take selected text as stdin

I'm trying to find a utility that I can use on a shell command line to
take selected text in any CDE/Solaris as stdin and just copy to stdout. What API can I use if I write this in java?
Any easier way to pipe selected window text into a program (e.g. lp)?
There used to be a get_selection command in Sun4, but it doesn't work in Sun5.
-willy
get_selection | lp

Ok, let me try this again.
I have a CDE windowing system running. On one of the windows, I simply select
text. It could be a shell window, a textedit window or whatever.
The old sun4 get_selection solution did not require pasting into the clipboard.
If I use cat in the way the responder suggests, then I need to copy and paste into the shell window as input to cat filling up the shell window unnecessarily. The window buffer may be limited which could cause overflow of desired lines.
Simply by selecting the text (which is now highlighted), get_selection would use that text as it's stdin so I can pipe it to any other program such as lp or save it in a file, e.g. get_selection > file.txt or get_selection | lp.
Having to juggle a temporary file is extra steps.
This is so basic, I am surprised it is missing from the current Sun offerings.
Also I tried to find the best Forum for user interface questions and to my surprise, there were none I could find. This forum was my best guess. Any other forum suggestions for this kind of question.
I didn't have the source for get_selection and it doesn't work in solaris 7.
I also searched for the API to access the selected text (the same text that 'copy' operates on), but couldn't locate it for use in my own program.
thanks for the responses so far.

Mysql upgrade issue

after upgrade i rebooted and ran mysql_upgrade as written on the main page. here's what I got:
mysql_upgrade
Looking for 'mysql' as: mysql
Looking for 'mysqlcheck' as: mysqlcheck
Running 'mysqlcheck' with connection arguments: '--port=3306' '--socket=/var/run/mysqld/mysqld.sock'
mysqlcheck: Got error: 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) when trying to connect
FATAL ERROR: Upgrade failed
I myself do not use mysql. It's installed as kde4 dependancy. Do i need to run mysql_upgrade?

How do I allow access of my mysql server to !localhost?

I just did an nmap of an arch box running mysql, but port 3306 isn't open. mysql is certainly running and local processes have no problem accessing it.
There are no entries in rc.allow or rc.deny, and I'm not running iptables.

Portability of VI's

I want to know about the portability of vi's. If I write a vi for a
LabView 6.1 for windows platform, can I run the same vi in the same
manner under LabView 6.1 for the Linux platform? (Assuming the same
hardware and such). The specific case I am thinking of is a computer
that dual-boots linux and win2k, and runs LabView under both, so the
hardware will be exactly identical.
My general question is, are LabView .VIs portable across different
platforms and architectures?
Thank you in advance,

Yes, but there are a few considerations.
(1) The first one that is likely to affect you is file paths. Never use strings to store file paths, as constants. The path separator ("\", "/", ":") is platform dependant. If you use a path data type to store your paths, as constants, then LabVIEW will automatically convert the path separators when it recompiles the application for the new target platform. If you store them as string constants, LabVIEW wont convert them.
(2) If you call shared libraries you need to make sure that you have a .so file in Linux, a .dll file for windows, and a .shlb file for Mac. The call library function will load whichever one it finds if you use a "*" character as the file extension when specifying the library path in your
Call Library Function node. For example, "MySharedLibrary.*".
(3) Don't use ActiveX; it isn't available on Mac, or Linux. LabVIEW's 3D Graph is an ActiveX Control, and won't work outside of Windows. Also, there are some LabVIEW add-on Toolkits, like the Database Connectivity Toolkit, that are windows only because they use ActiveX.
(4) Linux (and Solaris) has Pipes VI, windows doesn't
(5) Only windows has Windows Registry VIs
(6) If you use the Dialog Controls in your application, their appearance will change depending on the platform.
(7) Font problems are notorious, things resize and don�t display right, always. There are several methods of working around this problem, by choosing proper fonts, but none of them are perfect.
(8) You stated that they have the same �hardware and such�. NI doesn�t provide drivers for most of their hardware in platforms other than Windows. Even if drivers exist for Linux, most likely you will need to call different VIs in LabVIEW, t
han you will in Windows.
I am sure that there are a few more issues that I missed, but someone else will post them, no doubt.
Good luck and happy cross-platform wireworking,
