manage requests between acquisition and control program using agilent 34970 A

Hello
I realized an acquisition program of data with labview and agilent 34970, real-time acquisition works very well with a time you sample of a second... There is no problem
to complete the program and control the taps installed in a photovoltaic system, pumping system
I realized that a second program for the controlit is functional
but the problem is when I merge the two programs in real-time
This error is present at the execution of two programs at the same time, that is to say that they launch two request at the same time the instrument 34970 A
(the poster of agilent 34970A labview crashes)

-------------------------------------------------- --------------------------------------
what I want is to find a little thing programming to manage two outgoing REQUESTS at the same time in LabVIEW instrument and create a kind of delay between two REQUESTS

Sorry for the bad English

Thank you

If you are in the same executable, semaphores works well.  You lock the semaphore before making your order and demand.  Release after you get your data.  If the lock is already taken, then the semaphore just will wait until the lock is available.  Only one process can act both in this way.

  • What is the difference between Fdisk and Chkdsk programs?

    Hello:

    I don't think I have a common question of OS knowledge and I worked a lot with both, however for years so I forgot everything I used to know.  I was talking to someone Executibles MS-DOS command line and this person I know told me in email and I did not at the moment, but he said the following:

    "Fdisk and chkdsk are pretty much the same.

    Being an old Microsoft OS Engineer I knew it was wrong, however I've been retired since almost 20 years and I have not worked with either for a while.  I looked in the KB for articles explaining the difference between fdisk and chkdsk or define at least the two against each other, but there is no specific article I could find.  I remember the days when the scariest user had a problem, but they ran all third party software on their computer and have installed BETA version software etc so I'm sure you know the drill and this type of person.

    The person who said this about fdisk and chkdsk is one of those people.  It is a really nice guy, but a nightmare to Microsoft when you talk to a convenience store to the BONE for assistance.  Is there someone out there who could you, please, help me and summarize an irrefutable definition or description indicating the differences between fdisk and chkdisk?  I don't remember the basic functions both I widely used both, but too many years have passed and I don't want to sound like a fool trying to write about the differences.

    I'd appreciate any help I want to educate my friend and the intention is to not make this person feel like a stupid either.

  • Picture in picture book uses white between photos and filling when using "Adapt to the chassis" instead of the border color of page like in iPhoto

    I used the book of images to create a book in iPhoto several times because the line between the pictures and the filling when I use 'Adapt to the chassis', is the same color as the color chosen for the borders of homepage and text boxes.  It is seamless.

    I just tried to use the book of images in pictures but the line between the pictures and the fill to 'Adapt to the chassis' is white, and not same color I chose for the page border.  It is, therefore, very ugly.

    Is it possible to remedy this situation?

    first get a glimpse of your p = book - Preview a print project in Photos, iPhoto or Aperture to avoid problems - Apple Support - so you can see exactly what will be printed

    You cannot change how the program works so if the problem persists in the overview say Apple about the bug - http://www.apple.com/feedback/photos.html

  • Arduino/LabVIEW input acquisition and control engines step by step at the same time

    Hey, I'm doing my last year of electronic engineering project and I'm trying to control 2 Motors step by step with labVIEW. A microphone will be placed on a platform that the stepper motor control and adjusts the position of the platform according to noise levels read from the microphone. To control stepper motors, I use 2 controllers engines step by step Sparkfun.com.

    https://www.SparkFun.com/products/10267

    These controller requires input of pulse. I'll use a DAQ 6008, but I don't know if this can produce a pulse? I also thought using the Arduino to control stepper motors that work perfectly with the controllers, but it would be able to order the engines while gaining an analog voltage to the microphone?

    I appreciate any help you can give.

    But you can use LabVIEW to work with the Arduino using the tools described here http://sine.ni.com/nips/cds/view/p/lang/en/nid/209835

  • Choose between chance and control

    I have 2 questions.

    1. I have a random number and a control. My indicator value must be equal to the value of my control, however, when the user presses a Boolean button, a random number to be generated, the random number generator should always take precedence over the control.

    2. If I want to select the [2 4 6 7] random number of these 4 numbers only, which will be the best approach, because the random number generator generates the values in the range 0 to 1, but I want a random number of only these four numbers, i.e. 2 or 4 or 6 or 7

  • How to close contacts between prospects and notation programs?

    I've implemented a program challenging 1 week, whereby cases of potential prospects will receive our week 1 "here are some tips for you' type series and will be scored based on their interaction with this series of emails.

    For scoring, I use the standard ' BP programs - Lead Scoring "that accompanies our instant Eloqua on setup. It was an excellent program of scoring for us on other programs to feed lead, but does not quite correspond in this situation.

    What the BP - program Lead Scoring is currently:

    • The main potential goes first through the program and then explicit into implicit program, and then it is removed at the same time.
    • Update every few hours Eloqua pushes a contact and one of our contacts that have a certain threshold score is pushed into SalesForce.

    What I need the BP - program Lead Scoring to make:

    • It should continue to do what he did, and...
    • If the contact has received an email from our week 1 feed program (which indicates that they are in this program) he must fend off the head contact 1 week program, instead of simply remove from lead scoring to feed and let it sit in limbo until SF it resumes.
    • Contact still needs to get pushed in SF, but it must also have pushed back in week 1, feed the program so that they will receive all the emails that we promised and you have an additional opportunity for qualification.

    All the world faced a similar need? How did solve you this?

    Any suggestions?

    Thank you!

    What is the trigger that puts people in your notation program?  It's a program loader or a step in your innate program?

    If this is a step in your innate program, you could use step 'Add program' instead of 'Move to program? "  'Add program' does not their current step remove.

    If it's a program loader, my comment would be that people can be in several programs at the same time.  That means, if they are in the challenging program of 1 week and your feeder program puts in the Score to lead program, they will not necessarily be removed from the stimulating program.  It depends on the way in which the rules are set up of course.

    Does that help?

  • Problems of restoring a backup of Windows Vista backup and restore program

    I recently had to completely reinstall Windows XP, then the Vista upgrade, to fix a problem with updates of Microsoft.NET and ATI graphic driver.  In may, I made a full backup of my laptop using Vista resident backup and restore program, using an external hard drive to store the backup.  When I learned that I had to reinstall the operating system, I did another backup in August (but not complete) using the same program.  Just after this backup in August, I did the reinstallation of operating systems, with the help of the phone of Dell.  My original problems are solved.

    When I was ready to use the restore the Vista program, I had to choose among the two sets of data (May to August) about which I wanted to restore on my laptop.  I chose August, thinking that it would be later.  However, in Outlook, all my saved e-mail messages are gone, I have no e-mail address book and any current calendar entries.  These are the only things I noticed up to this and are not, but I have not checked all the files... they are large enough.

    The folder on my laptop which normally contains my Outlook data files shows only a file Archive and the very small current .pst data file for 7 messages in my Inbox.

    It seems that the backup of August was important to may backup and maybe most of my Outlook data are in the may backup.  How to get data from two backups in my laptop?  When the backup is a folder with the same name, you have the opportunity to write about it, not copy, or copy it and have 2 folders.

    I tried to copy all the data from the external hard drive in the folder of Outlook data on my laptop.  It will eventually be several files, and Outlook reads only the more recent, so I don't always get access to the data that I hope is here!

    Can someone please?  My life is in my calendar, I lost years of e-mail addresses, and much saved messages that contain important data.  Thank you!

    You must save the config.xml file adfc bean in the scope of the request this ways you can call the method any page bean.

  • Disable defender and Security Essentials due to conflicts, has blocked access and control other programs.

    Hello, I use Windows 7 on a HP G60 laptop. I disabled Windows Defender and Microsoft Security Essentials because I started running free Panda and Malwarebytes Antimalware version. Now an error window Defender blocking access and control of a large number of programs, the window message trying to force me to turn Defender. Disabling Security Essentials is causing other things to not work. I can not yet re - turn on Defender, if I try clicking on the link in the error window, it will not restart, expires.  Tried to turn it back on using the Task Manager, but there is no response at all if I click Start. Access to Services and programs in the start Panel are all both blocked by Defender error window.  I actually want defender and Security Essentials, because they are redundant and are in conflict with other programs I am running, but apparently they cannot be disabled without blocking access to my computer. I thought it was harmful to run all these programs of security in conflict between them, now I can't use my computer at all. Thanks for any advice you can give me.

    Thanks much for the advice. I have a few other questions. Defender is not separated from the essential? Then uninstall Security Essentials would have no effect on the Defender isn't it? My problem is that Defender deactivation now blocks access to many other programs with a Defender error window.  I read that Essentials was supposed to replace defender and Defender should have been stopped or disabled when Essentials has been installed. Is this correct? I didn't, got them both running.  When I installed Panda, I got a notification from Windows on the conflict and choose which program to use. Although I chose my own safety programs at the time, which was never disabled Defender or kept from running. So I finally did it manually by accessing the properties in Services to change the startup type to disable, which is when all the trouble started.
