How do I get this to run only once

I am using Labview and an E series DAQ to control a stepper motor. I downloaded a finite pulse generator to send out the number of pulses I need when a case is selected, but now my problem is that the vi keeps repeating the finite pulse generation, so it sends out 10 and then 10 and then 10... it keeps going. I need a way for 10 pulses to be sent out and then no more until the case is changed.
Thanks

If you use the example that ships with LabVIEW 6.1, titled "Finite Pulse Train (DAQ-STC)," one train of a specified number of pulses will be generated and then the VI will quit. If you are importing this example VI into your own custom program, you need to ensure that it is not called from within a while loop. Perhaps that is why you are seeing the pulse train repeating itself.
This example can also be found by clicking on the following link:

How to get lauchctl daemons/agents to run only once a day

How do you get a daemons/agents to run only once a day regardless of the error code of the .sh you are running?
(not I'm not looking for run once or run on reboot. I want a job to run at 3am every day and it has several bash commands in it. Regardless of the returns by any of the commands in the script, I only want this to run once - NO RESPAWN).

Ok still not working.. here is the plist
the .sh file does file processing and then uploads xml files to my server and should run once a day. Here I have it running at 11:45am. It completes and then runs again and again and again.
The plist is placed in LaunchAgents and loaded with $launchctl load com.iclassicnu.crontabtest.plist
ideas?

I just installed Firefox on a new HP 600-1120 with Windows 7 and it is only running in "safe" mode. Why? How do I get it to run in "regular" mode? How does "safe" mode differ?

> So now my question is, how can i fix this problem?
Use the Toshiba recovery disk or the Toshiba HDD recovery option.
If you dont have the Toshiba Recovery disk try the HDD recovery:
http://aps2.toshiba-tro.de/kb0/HTD1303440001R01.htm
This works only if the recovery image files from Toshiba are still on the HDD:
If you installed the system using another disk as Toshiba recovery disk, this recovery option will not work.

HT1688 I used a MC $50 Giftcard for the iTunes one day. It was supposed to update the games, and other apps on my phone. Only, it wouldn't go through, the credit card was declined. Still, I was charged 4 times. How do I get this back??

To Whom It May Concern:
I bought a Mastercard Giftcard for $50 the other day. It was only because the games needed updating before I could play them again, and my card on file had expired.
I kept getting a message stating the the card was declined. Also, it kept telling me to try to put in another card, or different form of payment.
I tried several times to get the MC to go through, and it didn't. It was not even showing that the card info even updated!
When I went to check the amount of the giftcard, there were 4 pending charges of $10.89 on it.
How do I get this money back? Please let me know as soon as possible.
Sincerely,
Queenie from Texas

I did but that was from a month before, I want pics I took after that backup time. It deleted without my consent like this is not cool. I had recent pics from my trip.

iCloud storage is not allocated by device. iCloud storage is allocated to your iCloud AppleID. You get 5GB of iCloud storage.

How do I get a case to run only once

I am using an e-series DAQ board to bring a pwm signal, then I use labview to use that signal to pick one of three cases. depending on the case picked a finite pulse stream is sent out. Currently the finite pulse vi keeps repeating because the the program stays in the case. I need a way to get labview to run the finite pulse output only once, and not run again until a new case is picked. I don't have the case in a while loop.
Thanks For The Help

I am still haveing problems so I will try and attach my program and see if you can help a little more that. It will probably be easier for you to look at this way. When you look at the diagram sequence 0 is the one the problem is in. In that sequence you will see a case structure and that is where the finite pulse train vi is. When case 1 is selected the finite pulse train will run again and again until I leave case 1. I need to have the program run the finite pulse train once and then wait and do nothing until the case is changed. The finite pulse train will be in all cases inside the case structure I just haven't done that yet, I am waiting until it works. The pulse train is used to move a stepper motor that is why running only once is im
portant because the stepper motor is used to position something.

My ipod 4th gen gets wiped clean of music anytime I sync. it then only redownloads some of the music in the library and wont upload missing songs. They show on the ipod grayed out. How do I get this to stop? re-uploading takes 4 hours.

my ipod 4th gen gets wiped clean of music anytime I sync. it then only redownloads some of the music in the library and wont upload missing songs. They show on the ipod grayed out. How do I get this to stop? re-uploading takes 4 hours and is never completed. I only get some of the 6000+ songs I have. This started when I updated to IOS5 i think.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Unsync all music and resync
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.

With my new macbook I attempted to open an older spreadsheet and get the following error message: "This spreadsheet cannot be opened because ti is too old. To open it, save it with numbers '09 first" So how does one do this when I only have ver3.1?

Numbers 3.x can only open Numbers '09 and later. You will need Numbers '09 to open Numbers '08 files.
If it is a single file (or only a few) you can email me and I will open and convert then email back. My email address is in the "Biography" of my profile.
You may have Numbers '09 installed. Look in the folder "/Applications/iWork '09" if Numbers is in that folder launch it, open the file you tried to open, and save. Then you should be able to open in Numbers 3.x

I have had this problem for close to a year. I have an Extreme base station, two Airport Express's and multiple G4 Mac's with up to date software. I have spent a huge amount of time trouble shooting, resetting, reapplying software and finally calling Applecare without any help. It would be great to get this problem solved.

It calls both the ipad and iphone when calling the associated email address for the ipad. However, when I call the iphone it does not call the IPAD.

There is no other way to bypass the combintation lock other than to connect the nano to iTunes and restore it to factory settings, erasing all content and settings from the iPod.
