First off, there is a dedicated mathscript forum that might be better to get your problems answered. (I see if I can have this thread moved from the LabVIEW board, else you can re-post over there.)
I see the same problem that (1) the outputs have no datatype and (2) all datatypes are greyed out, so they cannot be selected manually. (The input is trivial, just wire something and it will adapt).
I am not a text programmer, but I suspect that there is something wrong or incompatible with your code. I have not looked at the statements. Is this copied from an existing matlab program, for example?

  • Why I can not change the display when I turn the Ipad from horizontal to vertical position ?

    Please help to give me the guide line to solve the problem in my Ipad
    I can not change the display when I move the ipad from horizontal position to vertical position

    Have you got a lock symbol at the top of the screen next to the battery indicator ? If so, then depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can lock rotation either by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085
    If there is no lock symbol then try a reset and see if rotates after the iPad has restarted : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • Are you using the MathScript Node in LabVIEW or the MathScript Interactive Window?

    Are you using the MathScript Node in LabVIEW or the MathScript Interactive Window? I am very excited with the MathScript Node inside LabVIEW. However, I would like to see what other people think.

    Avalim,
    Personally, I am determining that I like to use the MathScript Node in LabVIEW.  It makes it easier for me to pass my data in and out of the LabVIEW environment!!  But, like you, I am excited to see what any other users think!!

  • MappedAttributeInfo(APPView.Node): must not modify the datatyp

    Hi,
    I used DropDownByKey element (DDLPROJE) and mapped it a contex element(PROJE).
    I tryed to fill PROJE with code below.No problem on compile, but when i run, it gets error below on line bold in code.
    How can i solve this problem?
    Thanks.

    Hi,
    I guess you did as below.
    You have created the context attribute PROJE in View Context as well as in Controller Context.
    And then you have changed the type of PROJE attribute in View Context by binding it to some Simple type.
    After that you have mapped this attribute to the PROJE attribute in Controller context.
    That is why it is giving that error.
    If my guess is correct:
    Then delete the context mapping - by right click on the PROJE attribute in the View Controller.
    Now in Comp Controller change the type of PROJE attribtue by binding the simple type.
    And now do the mapping between the attribtues.

    Dear Experts!
    I can not change the time in activity Appointment when creating: calendar -> month -> click on the day

    Help me this problem?

    You need to add that attribute using the config tool for your view configuration. Select the attribute All Day from the context node BTDATE in the available fields to your display field and then save it. It should now be visible in your UI and now you can select or uncheck it to make the time field enable. Check the below image

  • I have an iPad 2 and the newest apple tv. I do not get the option on my iPad to mirror on AirPlay. I've tried all the suggestions I've seen. Does anyone have a new idea?

    I have an iPad 2 and the newest apple tv. I do not get the option to turn mirroring on in the AirPlay function. I have tried the suggestions I've seen on here so far, but nothing has worked. Has anyone come up with a fix to this problem?

    Your Apple TV and iOS device (iPad) need to be on the same network subnet.  If they are you can verify when playing that the ATV is set as the output device by clicking the icon to the the right of the fast-forwrd button.  Or you can double-click the home button and swipe left twice to see this.

  • How to directly change the text of a tree node once its in the tree

    How can I directly change the text of a tree node once its in the tree.
    I have a property box which fires an eventevery time it is edited
    (this is currently just output to the screen via println)
    What i want is for the tree node to take the updated text that is in the text box every time
    thus giving tree labels that update as you type
    PS. i have access to the tree node (DefaultMutableTreeNode) from the code that hanldes
    the text box event

    ... use the setUserObject() method of your DefaultMutableTreeNode, that'll set the text of the node.
    however, you probably need to do a treeModel.nodeChanged(node) with your tree model, to get the display updated.

    Hi,
    What’s the OS version of your cluster node?
    The Microsoft Fibre Channel Platform Registration Service registers the platform with all available Fibre Channel fabrics and maintains the registrations. A fabric is a network topology where devices are connected to each other
    through one or more high-efficiency data paths. This service is used in support of storage area networks.
    This service is installed by default on Windows Server 2008, and the service startup type is Manual.

    I DO remember them but Apple chose to put them in Japanese and I can not change the language on Manage my Apple ID so I do not know if I made an error ,it threw me off , it was the wrong question Where did you fly to on your first Aiplane trip ? then I was unable to enter until 8 hours then called Apple Japan 4 times each time threy asked me would you like to speak with an English speaker,I said yes then they told me sorry today is Sunday no English speakers ,but they refused to speak Japanese, then I called 5th time and a kind guy could speak English we were on 1and 1/2 hours he got me to log in but the reset key chain could not be completed still pending.
    He said do not mess with that ! then I got a text from somewhere to reset 4 pins suddenly it was very strange I said to him that I got this pin this morning but it said you can use maximum 3 hours it had a UK number and I told him I do not like this and will not enter the code he said do not do it if it is from the UK and then I said to him ok you did a lot to help but we can not go any further ! and we cut of I went back to my computer to re do the ID but I found everything a mess so I call and a stupid sounding Japanese women with a squeaky voice came on I was calm at first and they want your phone number your IMEI number your iPhone serial number date of birth Address email address it takes 10 munutes to check then they ask what are you caling about so I try to explain my keychain is broken or problems with language security questions and can not change my pasword because the security question have failed me so it is ONE BIG HEADACHE AND I START I GET STRESSED she says Do want an ENGLISH speaker ,I say yes ,that guy i talked to earlier but I never got his name and first time I ever talked to him but they said he is not here so I said ok and then she said today is sunday so call back in the morning ,I said ,well ok in Japanese but they make you feel stupid because they do not want to speak Jap@anese with none natives and they are to busy,And they feel that I should not bother them ,then I say that Apple Japan is trying to refuse Apple foreign customers and then she wants to hang up and ask me to visit the shop ,but they are the same I have a very bad time with Apple Japan since they do not discuss software problems or security with customer meaning if you have a problem they ask you to come on a time 20 minutes max so they do hardware test and say you phone is fine then I say no I can not reset my ID they say you must call call centre so I am going around in circles ,When I call English it is usually Australia so if my problem is in Japan surely if do not want me to talk to them in Japanese and they ask me to call Australia but every time my call charge is expensive after asking them is this free because I have Apple care they say yes but when the call goes to Australia 0120 277 535 it might change to paid call so I call then I have to ask is this charging they say we can not give you that information ! so what can I do I have have been at the computer and phone all day on my day off work and in tre week I am so busy and can not use my phone I can not work without it ,this new technology for you ,they can not cope with the fact that the customer have problems yet they do not want to deal with us because they can not solve it and so it shows them to be useless they like to walk around in their cool tee shirts and retro shop but when it comes to functionality we are unwelcome they got the money so do not return because apple is perfect that nothing should go wrong .
    But it does somehow my English security answers do not work on a Japanese Question especialy if I did not choose that question I set  up the multiple choice In English and wrote the answers in English or Roman and set them langauge preferences in English, do you really think you can correctly write english name or word in Japanese they write a police patrol car  pato caa パトカア they do not have r and l .So it is my choice to make my security easy for me and as difficult for others to hack.But they also have patororoo choo meaning ' now patrolling ' so why they have pato caa patrol car and patoro patrol and have thousands of Chinese words kanji they can find patrol.
    I am getting off the topic but I am at a loss to fix this problem when they hold the keys and i have all the info to verify my ID.

    How do I get messages to go back to an AIM account? It's only seeing the iPad's Facetime email address and not seeing the old AIM account name that is on my desktop. I am using my iMac using iChat to talk to a newer iMac that doesn't have iChat. We had this working using Messages and Facetime (on the new machine) talking to my existing iChat account. One day last week, when Facetime rang, my kids answered on the iPad. Dang! Now it's all fouled up! The new iMac won't see my AIM account name and shows that I'm offline, because the iPad is off. We were able to call using "most recent call" in Facetime, but now I can't go and control that new iMac remotely to help with some email concerns the user is having. I'm trying to not personalize this too much, but it's grandkids talking to Grandma and Mom and Dad trying to solve new machine hiccups. Normally, I could just go in via iChat and control the other machine and troubleshoot, but I can't do it with Facetime only. My buddy list doesn't see  the other computer even though we are connected on Facetime right now. My name is not highlighted for the other computer. What could have gone so wrong?
    Any help would be appreciated.

  • When I try to upload a file it goes through the correct proceedure, but does not change the remote file i.e.Index.htm

    Hi
    I have an uploading problem to the server. The problem is when I try to upload a file it goes through the correct proceedure,
    but does not change the remote file i.e.Index.htm, or three stages1.htm.
    My Localroot folder is C:\Gods Plan Web\
    The site map layout is C:\Gods Plan Web\Index.htm
    The folder for the remote site is /public_html/
    Should the local root folder mirror the remote site, i.e./public_html/
    if this is so, what should I put into the
    (a) Local Root Folder box?
    (b) site map layout box?
    The FTP is performing well other than changing the intended file.

    You should be uploading only the contents of your local root to the public_html folder (remote root).
    The index.html you use as your site's home page needs to be in your site root. If you look at your Files window in DW, you should have something like the following...
    Site - Whatever you named your site
         index.html
         images
         pages
              page1.html
              page2.html
    If you have any folder between Site - and the index.html page, like...
    Site - Whatever you named your site
         mywebsite
              index.html
    It will upload to the public_html while still in that folder, so to find your page online, you would need to type something like...
    www.mydomain.com/mywebsite
    public_html should NOT appear within your local files and if it existed there, would cause a redundancy if uploaded. You would need to type www.yourdomain.com/public_html to see the uploaded pages.
    If you could post a screen shot of your expanded Files window while connected to the server (just connect and click the Expand button in Files, don't drill down into any of the directories), we may be able to see the issue.

  • I have updated Firefox to 8.0.1 but the main screen still says " You're not on the latest version of Firefox. Upgrade today to get the best of the Web!" What is the problem?

    I downloaded Firefox Setup 8.0.1.exe from the website to my desktop and opened it as an administrator. The available choice (once opened) was to upgrade. When the process was complete my version of Firefox was identified as 8.0.1 but the main screen still said - "You're not on the latest version of Firefox. Upgrade today to get the best of the Web!"

    This - http://www.google.com/firefox - is the old Firefox Start Page used by the Firefox 3.6 and earlier versions of Firefox, I don't think it is being maintained.
    Starting with the Firefox 4 version, Firefox is using a "local" Start Page with the address of '''about:home'''. It looks similar to the old Start Page, but it isn't exactly the same.

    Hi Guys,
    Every time when we login to SAP Business One, we are getting two identical security Alerts, that we needs to click "Yes" twice.
    Text of error: “The name on the security certificate is invalid or does not match the name of the site”
    We tried to install certificate, but it is not solved this certificate issue and the alert still pops up on login.
    I guess, something wrong with dashboard settings, but don't really know what exact and how to fix it.
