PING Example is not in that archive. This is only the actual PIPE function library. What you want to do is using "OGPIPE Open System Command" to create the pipe handles for stdin and stdout and optinally stderr. Then use "OGPIPE Write To Pipe" to write to stdin and "OGPIPE Read From Pipe" to read from stdout and optionally stderr. When finished close each opened pipe handle with "OGPIPE Close Pipe".

After installing the new Yosemite OS on my iMac I can no longer send email. I can receive email, but not send. I use gmail and can send email on the gmail (google) site, but not on "mail" on my iMac. Any others with this problem? What should we do?

After installing the new Yosemite OS on my iMac I can no longer send email. I can receive email, but not send. I use gmail and can send email on the gmail (google) site, but not on "mail" on my iMac. Any others with this problem? What should we do?

My gmail, which is correctly configured for Mail with gmail SMTP and Google IMAP, works for awhile on Mail, which I leave open while working on other applications. But several times a day I get msg from Google: "We recently blocked a sign-in attempt to your Google Account" . . . and requiring me to verify my account details, re-enter passwords, confirm security settings (or change them from "disable" to "enable less secure methods" and so on). In Mail I also have tried "taking all accounts online", and re-entering my gmail password inside Mail account settings. These steps successfully re-set comms between gmail and Mail ... for awhile, then it happens again. Enough occurrences over a work day that I just quit Mail and revert to accessing gmail directly. Apple Care advisor and an Apple knowledge base article say that Apple can't deal with this, as gmail is third-party app, and they refer me to gmail, and so far I've found nothing helpful there.
From today I also have several instances of a window saying "Mail has unexpectedly closed" and asking me to Re-open it.
I also use Yahoo mail, which stops working with Mac Mail at the same time as gmail, but I do not receive notices to re-verify from Yahoo.
I recently upgraded from Mavericks to Yosemite. The Mail problem happened occasionally with Mavericks but is far more frequent with Yosemite.

I cannot connect to my outgoing email server on my macBook pro, yet I can, for the same email account on my iPad. Also I can send emails from the other email account I have on my MacBook...really confused can anyone help?

Sometimes deleting the account and then re-creating it can solve this issue
Write down all the information in accounts before doing this
Highlight the account on the left and click the minus button
Then click the plus button to add the new account and follow the prompts

Other than iMovie, GB always incorporates the audio files into the GB package. So just save or move the GB project to the external drive, and you're done - anything you import, edit or record will be saved to the external drive.

How do I send email and web pages to a shared printer on home network. I verified that I can send documents to the shared printer.

My home network (one wireless computer using Windows 7--the other using Windows XP) share a printer, but I can't send web pages or email to the shared printer. I can send documents to the printer, so I know that connection is set up properly. Could Firefox be blocking this function? If so, how do I configure it. Both computers use Firefox exclusively.
== I never could share the printer when on websites.

How to use HyperTerminal to send characters to the cRIO

Hello, I built an RS232 serial cable using three wires interface of serial port (Rx, TX, GND). And I connected it between my computer and the cRIO. I would like to ask is it possible to use HyperTerminal to send characters to the cRIO? What vi. do I need to do so?
And is my cable interface correct? Do I need to connect other pins besides Rx, TX and GND?
Thank you very much for helping.

So did it or did it not work when you typed words in by hand in hyperterminal? I'm not clear on this from your response.
What kind of things are you trying to send? What code do you have on your SBRIO to handle the other end of the communication.
It could mean your connection failed. It could mean you have the wrong cable between the two (null modem vs. straight through), it could mean you aren't sending the data in the same way the code on the RIO is expecting. Look at such things like any termination characters you send at the end of the message.
It's kind of hard to help without know more details of what you are trying to do and whether it is working for you in Hyperterminal or not.

Sending characters to the printer

Hello together,
we are trying to send raw data or control characters to a printer using the standard "Universal / TextOnly" printer driver in order to print barcode data on a special printer. This works fine by using Windows Notepad.
Unfortunately, Java only provides printing with a Graphics context. So we have not succeeded so far.
Has anyone else had the same problem and how did they overcome it?

Hi again.
This is distilled from the JavaCOMM API.
This code is changed from the example and looking at the docs for a minute. I don't know if it compiles but it should :-)
import java.io.*;
import java.util.*;
import javax.comm.*;
public class SimpleWrite {
    static Enumeration portList;
    static CommPortIdentifier portId;
    static String messageString = "Hello, world!\n";
    static ParallelPort parallelPort;
    static OutputStream outputStream;
    public static void main(String[] args) {
        portList = CommPortIdentifier.getPortIdentifiers();
        while (portList.hasMoreElements()) {
            portId = (CommPortIdentifier) portList.nextElement();
            if (portId.getPortType() == CommPortIdentifier.PORT_PARALLEL) {
                // if (portId.getName().equals("LPT1")) {
                if (portId.getName().equals("/dev/lp0")) {
                    try {
                        parallelPort= ParallelPort
                            portId.open("SimpleWriteApp", 2000);
                    } catch (PortInUseException e) {}
                    try {
                        outputStream = parallelPort.getOutputStream();
                    } catch (IOException e) {}
                    try {
                        outputStream.write(messageString.getBytes());
                    } catch (IOException e) {}
}Hope this helps,

I have 2 email addresses set up on my iphone 5, 1 can send mail and the other can't... have tried deleting and adding the account, no luck, have tried all suggestions... anyone help?

I have recently purchased the iphone 5S and have two AOL email accounts set up on it. They could both receive and send mail on the first day, but from the second day only 1 can send mail (both still receive). I get an message saying "Unable to send mail. A copy has been placed in your Outbox. Sending the message content to the server failed." This has been the response now for 3 days and suddenly this morning, I was able to send an email from this account, but only the one and now it's back to that same message. I have deleted and added the account again, using various methods. I even reset my phone and set it all up again from beginning with no luck. It is very frustrating and I am unsure why I can't send from both accounts, especially being that they are the same provider. I have read forums and it appears many have this same problem and I wondered if anyone has had it recently on this phone and how they fixed it. Someone said just use the AOL app to send from this account, yes that can be done, but it's inconvenient having to sign in all the time when i have a mail app that should work automatically. Any suggestions would be welcomed!!

I am not sure if this issue is going to help you but lets give it a try.
I know that where im from, which is the Netherlands, I am not able to sent e-mails from my iPhone or any other mobile device by using 3G or a random WIFI acces point. The provider only allowes you to sent e-mails when you are connected to a network of there own. Which means if you have provider "101" and your email settings are set up for this provider in your iPhone but your using the network of a friend of yours which is provider "202" you cannot sent emails from his network. Though you can receive them you may not sent.
As I said, I am not aware if this issue is the same for you totaly depents on the country and provider your using.

I cannot receive emails on my ipad but I can send them. When I try to fetch emails a pop up box tells me to says verify your incoming email setting in settings. I have, it is correct as I am receiving emails on my iPhone with the same incoming address. I have tried deleting it and putting it in again but that does work. The wifi is working fine when using the Internet. Has anyone any ideas what is happening and how I can rectify the problem?

Is there an ARD command or Unix command that I can send to reset the desktop background image to default?

I was forced to create a local user with an automatic login on all of the machines in the building. I listed off many various issues that could come arise by doing this but was tuned out. Now people are changing all of the desktop backgrounds to some pretty inappropriate images. I forewarned the person ordering this that this may be one of the many issues that would arise when doing away with our server based logins, and now I am charged with fixing every desktop every time someone changes it to something inappropriate.
Is that an Apple Remote Desktop command or a Unix command that I can send through ARD v3.5.3 to the machines to reset the desktop background image to the default Aqua Blue jpeg image located in the /MacintoshHD/Library/Desktop\ Pictures/Aqua\ Blue.jpg.
The machines that I am dealing with have OS X 10.4.11, OS X 10.5.8, OS X 10.6.8, and OS X 10.7.4 installed on them, but the OS X 10.4.11 machines are the ones that are creating the biggest issue so I would like to deal with those first.

Ya, I'd love to have the computers connected to the Xserver, unfortunately against my heeding, I was ordered to take them off of the Xserver, so they only have a local account that automatically logs in on startup, and even though I have Parental Controls set, I can not stop them from going to Safari, selecting an inappropriate image and setting it as the background, so now I’ve been ordered to fix all of the backgrounds that people are messing with.
My Xserver is running OS X 10.4.11 Server Edition. Yes, I would love a new server, but that’s not happening due to budget cuts.
So what I am hoping for is a command that I can put into Apple Remote Desktop v3.5.3 and push out to all of the computers via its Unix commands and reset all the desktops to their default image.

Why can´t I wire the offset input in the Write File Function when I use datalog files ?

Hi !
I have a datalog file, in which I save variant data several times in diferents VIs, I runs these randomly, and I would like rewrite only a part of the file, but I can´t wire the offset input in the Write File function to indicates the begins and save the data in the point that I want.
I need your help thanks.

Second Write in a datalog file.vi ‏19 KB

Hello.
I THINK that the reason why the offset input is disabled when you are working with datalog files is that you do not know how many bytes each entry of the data structure will ocupy.
When you have a binary file where you store, for example, an array of double precision floating-point numbers, you know that each number ocupies 8 bytes, so you know that when you want to read the 21st number of the array you need to skip the first 160 bytes (20 numbers x 8 bytes/number).
However, with datalog files you can store very diverse data structure, usually including strings, like in your case, which means that you do not know how many bytes to skip to be able to read or write to some particular variable of your data structure.
If what you want to do is to not overwrite the contents of an existing file, but to append to it, what you probably will have to do is read the whole contents, append to the data in your program, and write it all again.
Hope this helps,
Alejandro
