Is there a way the user to change the equation in the formular node from the front panel on the fly, dynamically?

Try the Parser VIs (also known as LV Mathematics VIs, or simply GMath VIs) located under the Analyze>>Mathematics palette (not in the Base package). You might want to start with the "Eval Formual Node.vi" located in the Analyze>>Mathematics>>Formula palette. There are many differences between these G-based, dynamic formula VIs and the LabVIEW formula node, but these VIs often prove quite useful when your formula changes on the fly. For more detail on the differences, see the LabVIEW Help file (Cntrl-Shift-? from within LabVIEW) under the topic "Mathematics VIs, parser differences with Formula Node".

    Is there a way the user can change the equation in the formular node from the front panel on the fly, dynamically?

    Sorry, I don't think so. That would be pretty cool if you could create a property node for a formula node and then enter a formula on the front panel and use it to update the formula. But you can't create a property node for a formula node and the only way of modifying the formula is by typing it into the formula node on the diagram. And you can't modify a diagram of a running VI.
    You could create a VI which is only a formula node with the maximum number of inputs and outputs you expect. Have a button on the calling VI to Edit Formula. When the button is pressed, use a VI server to display the front panel on the formula VI, display a dialog box telling the user how to display the diagram of the formula VI, then stop the calling VI. (You can't edit a sub-VI while t
    he calling VI is running). The user will then need to rerun the calling VI to use the new formula.
    You might be able to do something by calling MatLab or something like that to get an interactive formula window.

    Dear all,
    I just downloaded the now IOS7 on my iPhone4S, the background picture has faded a bit, the folders that contains my icons are solid bright gray and the keyboard is pail/bright gray and I can hardly see it. Is there a way that I can change the colors, the shades, etc? I don't like the new layout, it's too bright and too pale, like the face of a Georgian monarchy. Thank you for your help and support.

    I changed the background picture, which is a dark pink flower, now the folders have become solid pink! Not esthetically pleasing

  • Is there any way to control or change the email notification format deliver

    Hi,
    Is there any way to control or change the email notification format delivered by iBots? I have created an iBot to deliver the scorecard report to the team with type chosen as 'Attachment (HTML)' option. With this definition of iBot - notification being sent in MIME HTML (.mht) format. Due to some security settings at my email client - the attachement gets quratined because of .mht format. So, I am looking for an option to send the notification only in HTML (.htm) format with which I don't have any issues with my email client?
    Any help is really appreciated.
    Thanks,
    Vency

  • Is there any way that I can change ownership (not authorization) of a song so that I don't have to go between my parent's family account and my new account?

    So a little backstory i joined the army and get to go home and use the account where the majority of my music is very little, but now when i try transferring these songs to a new device some of them aren't authorized, and I don't want to go through this every time i get a new computer or ipod/iphone.  Is there any way that i can change ownership of a song or other file so that a different account is the one to authorize its use?

    No.

  • My iCloud on my phone is undJer another persons account I however am no longer with them and want to cut all ties and is there any way for me to change my iCloud account or will it affect my phone? And it's photos, apps, music?

    My iCloud on my phone is under another persons account I however am no longer with them and want to cut all ties and is there any way for me to change my iCloud account or will it affect my phone? And it's photos, apps, music?

    You have to delete the iCloud account but you can keep all your data such as Contacts, Calendars etc. when you delete the account you will prompted to "Keep on my iPhone".
    All your purchased content (like apps and music from iTunes Store) belongs to the original ID and you have to re-Purchase them under your Apple ID.
    Photos in Camera Roll remains in Camera Roll.
    Photos in photo stream that are not in Camera Roll must be saved in Camera Roll.
    Photo that previously synced from iTunes remains in photo library until you synced with another iTunes library (another computer).
    Also sign out from iMessages, FaceTime and Home sharing (Settings>Music)

  • Is there any way to block PR changes when PO exists in project builder

    Dear All,
    Could you please advice...is there any way to block PR changes (quantity,price, etc) when PO exists in project builder ?
    Many thanks in advance.

    Hi Nies,
    If you are not using the material then you can go for Validation, under Operative Structure> Network> Validation.
    Attach the validation with OPSA click on Automatic.
    In the second scenario if you are using Material Component, as Mr.Muralidharan said OPSG there you can restrict the change by selecting Error Message.
    1. Tcode OPSG in Setting see all the object are selected.
    2. Click on Component tab under change in Purchase Order Exist tab select Error.

  • I have adobe elements 6 program and my disk got distorted.  i have all my serial numbers still as i have all packaging.  is there a way the program can be downloaded.  my computer had to be wiped out and was trying to reinstall

    hi.  i have the adobe elemenets6/premiere elements 4 package and my disk has gotten destroyed from getting all scratched up.  my laptop i had my program on had to be wiped out and everything has to be reloaded.  is there a way the program can be downloaded from the internet? i have the packaging still where it shows my serial numbers.

    iPods do not work with "accounts."  They work with your iTunes library.  You don't have to set up a new iTunes library for each iPod.  One iTunes library can sync with as many iPods, iPhones, and iPads as your own, at the same time.  iTunes connects to and treats each device separately.
    However, if your iPod nano is set up for automatic syncing with an iTunes library that is NOT your current iTunes library, you cannot sync your current library to it without replacing its existing content.  Do you have access to the previous iTunes library, the one the iPod currently synced to?  If so, you should transfer your song files from that iTunes library to your current iTunes library.  Then, sync our iPod to your current iTunes library.  You can post back to get more info about the procedure.
    If you don't have access to that previous iTunes library, the approach is to first offload the song files from the iPod to your computer's drive, then add the song files to your current iTunes library.
    You cannot use iTunes to transfer song files from iPod to computer, except for songs purchased from the iTunes Store.  However, there are third-party methods and utilities that can transfer from iPod to computer.  If you do a Google search on something like "ipod transfer," you should get some links.
    You can then sync your iPod to your "consolidated" iTunes library.

  • Is there any way to do a mass copy and paste of song titles from the "name" column to the "sort name" column? I know it can be done with individual titles but I have over 6,000 titles in my library.

    In iTunes, is there any way to do a mass copy and paste of song titles from the "name" column to the "sort name" column? I know it can be done with individual titles but I have over 6,000 titles in my library.

    Thank you. I have heard of Logic Pro 7, but I have never personally used it. I'm still growing in the world of Composition, and I know that it is something I will be studying in one of my Computer Music classes coming up for my degree. I think it is something I will look into getting once I can justify the price of it. I guess for the time being, I will continue to play and grow in my ability to use and take advantage of GB, and then see what I can do about or with Logic Pro when I'm ready. The thought of spending $1000 for a program is hard to bite, because I've already spent a lot to produce my music, not only electronic music, but also chamber music and so on. I had no idea it would be so expensive to dive deep into the world of composition! lol.
    Finale 2007: $500
    Sibelius 4: $500
    Jam Packs: $400
    Midi Keyboard Interface: $100
    PowerBook: $1700
    Printer for printing scores and analysis: $150
    Logic Pro 7: Oy!
    As you can see it adds up very quickly...that doesn't even include my personal instruments and study materials.
    Thank you for your input, as I haven't really worked much with LP, and therefore didn't know which features are available. I will talk with some of my Composition buddies, and professors and see what they have to say as well, and who knows, I may be able to get the express version through one of them.

  • Is there a way for my daughter or her friends to block their numbers from showing up on activities page. At first i could see them, as of yesterday i can no longer see the numbers in the activities page. But i do see that she has texted them when looking

    Is there a way for my daughter or her friends to block their numbers from showing up on activities page. At first i could see them, as of yesterday i can no longer see the numbers in the activities page. But i do see that she has texted them when looking at her phone.

    First of all, there is no need to put the entire text of your post into the title of your thread.
    Next, does your daughter have an iPhone? Do her friends have iPhones? If the answer to both questions is "yes", then it is possible she is not texting them, but using iMessage to communicate with them. iMessages will not show up in the texting traffic on a line as they are not texts, but messages sent thru Apple's servers.
    For all "texts" to show up in the texting activity of an iPhone, you must disable iMessage on the device. Any messages sent as iMessages(blue bubbles around the text) on an iPhone will not show up in any texting activity.
