Looking for occurrence RefNum vi

Hi all,
I am looking for the occurrence-RefNum-vi in LabView 5.0f2.
The only functions I found according to occurrences are
advanced->synchronisation->occurrences->generate/w​ait on /set
occurrence. So where's the occurrence-RefNum-symbol, which is mentioned
in the Online-Reference.
Thanks, Alexander Salim

The "Occurrence RefNum" is not a function, it is a control(indicator)
found in the front panel palette "Controls >> Path & RefNum >> ...".

  • Occurrence refnum - access from a different vi.

    Hi,
    Labview help enticingly has this to say about Occurrence refnums:
    "Occurrence Refnum—Used with the Occurrence functions. Use this type of refnum when you generate an occurrence in one VI but want to set or wait for the occurrence in another VI."
    This is exactly what I want to do. I can create an occurrence refnum in vi #1 but I just cannot see how to 'get at' the refnum in vi #2 without using something like a global variable to pass it.
    The vi's are all dynamically loaded so (unless I'm missing something else as well, very likely!) it is not possible to wire the occurrence or references.
    I'm a 'C' programmer just starting out with Labview so please don't assume I know *anything* for sure.

    And to extend the idea I have used AE's to share data not only between threads and between exe's, but also between machines across a network by exposting the AE and invoking the AE using VI Server call by reference in which case the call is mad on one PC and the inputs passed to the AE are transported across the network to the target where those inputs are used to call the AE on the target. The results of the AE method are then retuned to the VI server layer which in turn passes it back to the calling VI as if the AE was just a normal sub-VI.
    The Un-initialized SR appears to be implmented as a "static local" (forgive my C jargon since it is very rusty) where the data space for the SR is not recreated on each cll but persist fromcall to call.
    Ok, I've read a lot more now and I see that the USR technique seems to be officially sanctioned by NI. I was worried this might be exploiting undocumented behaviour which could change between compiler revisions. "Static local" is fine by me!
    The real power of the AE comes into play when you promote it from what is often called a FGV (Functional Global Variable that functions like a global having a write and a read) to an AE by encapsulating the operations that act on a data structure (in the SRs) and returns the results to the same SR thereby preventing the possibility of a Race Condition. Race Conditions are part of any multithreding environement and since LV is by default multithreaded, we can't willy-nilly go off and ignore race Conditions.
    It boils down to the same effect as wrapping every bit of code that accesses the data in some form of lock, whether that be a mutex, semaphore or whatever, but the encapsulation of the functionality with the data is quite elegant. I wasn't planning to ignore race conditions.
    In the case you outlined above you were using controls and indicators to share data and planned to use Semaphores to protect them. In theory that could work if you only used property nodes to read and right the objects. Using a local variable of the control would present an potential Race Conditions becuase of the way locals are implemented (Search for more on that topic) since they have a "special back door" that uses a buffer to apply the update without getting the UI thread involved.
    I have tended to do all reads and writes using property nodes because it isn't possible to wire data into a control. Plus, I read all sorts of warnings about local variables being inefficient and consuming lots of storage space. I didn't see any warnings about property nodes causing a performance hit in the help pages - in fact, I got the impression that the 'value(signal) property' would force the control to update but the 'value' property would not. Having re-read that section I now see that it is referring to the generation of UI events rather than updating the control. The two things just merged in my mind. I also see that Google has *lots* of info on the property node/UI thread switch problem.
    I found a lot of material explaining the traditional multi-thread interleaved read-modify-write problem - I assume this is the cause of the race conditions you're referring to? 
    And regarding the UI thread...
    If you did implement your scheme using property node >>> value you would be forcing all of your data acces to operate in the UI thread (which is single threaded) incurring the over-head of thread swapping added to dealing with the bottle-neck of doing most of your work in a single thread. Running that code on an eight core machine would swamp one of the cores and leeve the other seven to twiddle their thumbs.
    Yeah, that's bad news. Do you know whether the UI's of all top level windows in one .exe run in the same thread?
    "No Sir, Don't like it." (Mr Horse from Ren and Stimpy ?)
    Stepping back and doing the big picture thing for you...
    LV is often looked at as just another programming langauage. This is true on the surface but "the devil is in the details." (Ross Perot). Since LV uses a data flow paradigm, development in LabVIEW is well served by ading an additional phase to the traditional design work which is very similar to the "Data normalization" applied to data bases ("The key the key and nothing but the key so help me Codd."). Altough I have no formal training in that area I am married to a DB-Guru so I have an informal awareness of the ideas.
    I thought Labview was supposed to be 'programming made easy for electronic engineers'. It's funny, really, because I've only been timkering with it for a few weeks and I'm already up to my neck in multithreaded programming issues while just trying to put together a fairly trivial program with a few windows and a bit of data. I'm quite enjoying it, but I hadn't expected to be so concerned with what's going on under the hood quite so early. NI should do a course entitled "Advanced Labview for Complete Beginners".
    the Dta analyisis work amounts to looking at the data structures I plan to use in an application and doing sanity checks and drawing up data paths to help me streamline my designs.
    Some of the things I look at BEFORE CODING are;
    1) Are the values I am grouping together used together? If not I seperate them.
    2) What type of operations are perfomed on the data? The processing steps may benefit by me structuring the data as an array of clusters rather a flat cluster etc.
    3) How big is the data set? Large data sets get special attention because they can sneak up and bite you. Benchmarking may be involved in this step so I know about perfomance issue ahead of time.
    4) How busy is the data path? Busy data paths (DAQ to logging in high speed apps) is of particular concern. I have had to implement duplicate DAQ systems to provide a second data path for information coming from a RT machine or used SCRAMnet to provide the perfomance I need.
    5) What all needs to touch the data? This combined wiht the above help to suggest where I am going to put the data. Do I put it in an AE so it can be shared and mashed from multiple locations, Do I put it in a queue to get the raw dat there fast...
    I can probably go on a bit more but my point is it is only after the data anaylsis phase that I have a good idea what types of mechiansms will be used for each data structure.
    That's all good advice and makes a lot of sense.
    Still trying to help,
    And I very much appreciate it!

  • Looking for formula to fill dates of particular days of week for a given month

    Hi
    I have a Numbers document with a sheet for each month of the year, named "January", "February", "March", etc.
    Each sheet contains a table as follows:
    I am looking for a function that will calculate the dates in a given month that I am due to see each client, based on the year (contained in a single cell table on a seperate sheet) and the month of the sheet (I am presuming that a function can refer to the name of a sheet).  These dates would populate the cells under "Session 1", "Session 2", etc. (for some days of the week there may be only four sessions, for others five).
    I hope this is clear, and would be grateful for any help in getting this working.
    Thanks,
    Nick

    Here's an example, using September, 2011 as the month.
    Main Table:
    A1: =DATE(Year :: A2,9,1)
    This calculates the Date and Time value for midnight at the beginning of the first day of the ninth month of the year indicated in cell A2 of the table "Year" (September 1, 2011). It uses a Custom format to display only the month and year of this date. The Dates calculated in the rest of the table depend on the Date and Time value in this cell.
    A2 - A11: Entered data. Not used in calculations.
    B2 - B10: Entered data. The text values here are used as search-for values, and must match the text values in column A of the table Weekday lookup.
    C2, Filled down to C10: =$A$1+MOD(7-WEEKDAY($A$1)+VLOOKUP(B,Weekday lookup :: $A:$B,2,FALSE),7)
    This calculates the Date corresponding to the first occurrence of the weekday indicated in B during the month in A1. The result is a Date and Time value (used in formulas to the right). The cells use a custom format to display only the Day (of the month) number.
    D2, Filled right to column F and down to row 10: =C+7
    Calculates the date seven days after the date in column C.
    G2, filled down to row 10: =IF(MONTH($A$1)=MONTH(F+7),F+7,"")
    This is the same formula as used in D2, but adds a check to suppress the calculation if the result is not in the same month as other dates on the table.
    Year: The requested single cell table to record the year.
    Weekday Lookup: A lookup table from which to retrieve the weekday number for the day in column B of the main table.
    Custom formats:
    Select cells C2 - G10
    Open the Inspector > Cell Format Inspector > Date and Time
    Delete the unwanted elements from the workspace in the Inspector.
    Repeat for cell A1.
    Regards,
    Barry
    PS: Numbers cannot use the Sheet name or Table name as data for a formula unless the name is placed into a cell on a table.

  • Looking for an App that supports Text Searching in PDF (more complex finding text))

    I try to explain it clearly since my English not good
    when I using Ipad to search with some app like PDF expert. I can search words if I only type one single words or I type more than one words but these words are continuous in one sentence. Example like this
    In this case. I type "and for the", and I got the result, because these three words are contiunuous in one sentence
    But if I type words that not continuous but seperated in the file like this one. I don't get any result.
    So, I'm looking for an app that read pdf and can search multiple words at same time. Like what preview does in the mac
    See in the mac preview, we can search different words at same time and still get all the results.
    So, Is there any similar PDF app that offer same function on IPad?
    THanks so much

    Yes, PDFPen for the Mac does do multiple word searching.  I just tried it using this example:
    I searched the iPad User Guide for "switch control".  It only found those two words together.
    Next, I searched for "switch".  It found additional occurrences.
    I did find, however, that I was required to place the two words "switch control" inside double quotes to find the two words together (and only that string).
    UPDATE:  Oops, sorry, the above statemant about the double quotes being required is false.  Sorry, I used Preview by accident when I wrote that.
    Indeed, PDFPen works just as you seem to want ... searching for "switch control" (without quotes in the search string) finds only those two words together.
    UPDATE 2:  Oops ... it sounds like this is just exactly the opposite of what you want.  You are looking for something that, when searching for "switch control", finds all occurrences of "switch" and all occurrences of "control".  If that is right, PDFPen won't help you.

  • Looking for MSI FX5900 TD128 BIOS !! Need to flash back from 5950

    I had flashed my BIOS a couple of months back using the WFFLash utility of Leadtek and since then ive been gettin low scores on 3dmark03!
    Overclocking my 5900 once get me to get a 6300 3dmark03 score and now it doesnt go over 5800 or even less!!
    I was hoping if some1 could either give me a link or if some1 had the BIOS of the GPU i own, it was be grateful!!
    Even has any1 else encountered this low scores after their Flash!
    Oh yeah which utility do i need to re-flash - WFFLASH or NvFlash!
    Hope to find some help here ! !
    THanksss !!  

    Utk,
    The BIOS is static and flashing back probably won't make things better. I believe your scores or performance is suffering from OS decay. It might be a good idea to review all the software you have installed since you flashed your BIOS and see what's running in the backround. Perhaps even a fresh install of the drivers, maybe even a fresh install of the OS.
    Read this link, it saves me the time of going into detail http://www.computerclub.org/tips_tricks/tip_performance2.htm

    Looking for performance degradation
    Before I move on, let me point out that there's another area where benchmarking software really shines for computer users and that is in keeping an eye out for performance degradation due to OS (Operating System) Decay.
    This type of problem is little understood but very common. Let's take a closer look. As you've been using your existing operating system over time, you've probably installed, upgraded, and uninstalled numerous applications. In addition, you've probably added and removed lots of hardware and device drivers. Furthermore, you may have upgraded your operating system with a multitude of patches, bug fixes, and updates.
    Considering all the wear and tear these types of operations put on your operating system, chances are good that you've experienced OS decay first hand. Some of the symptoms of OS decay are frequent system lockups or crashes, strange error messages, unusually slow performance, and Windows directory that's bloated with files.
    Of course you must realize that OS decay is actually a natural occurrence that results from the heavy use of your system. You could look at the OS decay problem much as you would look at an aging automobile—no matter how well you take care of it, eventually you're going to have to buy a new one.
    Fortunately, you don't have to buy a new computer to solve the OS decay problem; you just have to rebuild the operating system from scratch.
    As such, the question is not if you must rebuild, but when you must rebuild. If you regularly check your computer and keep tabs on your system's progress over time, you'll have a much better picture of when the OS decay has gotten so bad that it's degrading the overall performance of your system.

  • Looking for vowels...

    I need a helping hand with this project. Is it possible to use a for loop and then scan through a string the user inputs to look for vowels(aeiou)
    then print how many a's there are?
    I'm not askign for somebody to do this for me...but could you give me a step in the right direction?

    Here's a more generic (and re-usable) way of doing this://---------------------------------------------------------------------------------------------
    * Finds the first occurrence in a string of any character in a set of characters.
    * @param string The string to check.
    * @param chars The characters to search for (the function searches for the individual

    * @return The index of the first character found (-1 if none found).
    static public int firstOf(String string, String chars)
       int first = -1;
       for (int i = 0; i < chars.length(); ++i)       // For each of the characters
          int index = string.indexOf(chars.charAt(i)); // Look for it in string
          if (index != -1)                             // If we find it

  • Movie rentals that I downloaded onto iMac with Lion to do not show up on ATV 2 in menu for computers.  Purchased movies show up just fine.  What to do or look for?

    I have an imac that is running lion and an Apple TV generation 2.  I have rented a movie from itunes and it shows up on my imac in Itunes under a rental icon, and will play fine on my computer.  However, it does not show up as choice to play on my apple tv.  I have homesharing enabled and everything else works fine including purchased movies that are on my imac, but no where does it show rental movies. 
    What do I look for?  What do I do to play the rental movie on my apple tv 2?

    Answer to my own question:
    Wait until the downloaded rental has completed its download to the imac.  This took a long time for me, since it was part of several things that I was downloading at the same time.
    Finally, it showed up on my apple tv.   Interestingly, I was able to watch much of the movie on my iMac before the movie finished its download and was available to the ATV 2.

  • Looking for a Darknet/Secure BBS app

    I have been a fan of Haxial KDX for the longest time, but due to the bugs, etc., I would like to move on.  I'm looking for a secure darknet/bbs styled program that supports chat, filesharing, and of basic user management (who can login, who can't, etc..).  I have been asking this question all over the web, and haven't gotten (or found) a single response.  Waste has never worked right for me, by the way.  I would definitely prefer it to be open source, which is why I thought it best to post here.  Please help out, or at least direct me somewhere where I should ask... Thanks.
    As an aside, the guy who wrote KDX and Hotline (Adam?? Hinckley) claimed on the Haxial website that he is willing to sell the project.  I wouldn't mine purchasing and restarting the KDX Project, but I've been unable to get in contact with him.  So...if you are him, or know him, or own the rights to Haxial KDX and all related projects...$$$$$

  • Looking for a simple, standalone desktop app for web stats

    Well, I see they've changed the forums here again. SIGH.
    Anyway, a certain web host has eliminated AWStats from it's shared hosting. So I used Webmaster Tools. And now they've changed, and no longer display the simple visitors and hits. Google Analytics is way too complex for what I need, as are many of the stats programs I've looked into.
    I can download the daily Apache log files, that's no problem. Just looking for a small standalone program to import these and show the data like AWStats.  Any suggestions? The only other options would be to go to a different web host. Not a big deal overall, but I would rather not deal with the hassle, especially the migrating the database.

    Not sure of standalone 'desktop' apps. But check out http://www.openwebanalytics.com/ and Web Analytics in Real Time | Clicky  - they're both very intuitive and easy to use with a lot more simplified stats than Google Analytics.

  • Looking for Video playback app, like a DDR

    Hello, I'm looking for a program to cue up and playback quicktime files for live broadcast off of the computers hard drive. Kind of like a DDR but all running on the computer. It needs to have the ability to cue up files based on keystrokes, like 123 enter = playack of 123, and be pretty quick about it.
    I found Playbackpro.... at WWW.DTVideolabs.com but I'm looking for some other options.
    Thank you.

  • Looking for a real photo editing app.

    I'm looking for something that can precisely resize and crop. None of this slider bullcrap where you can't get pixel level precision. I'd like to be able to crop at exactly 640x960 for example, or resize to exactly 820x620, etc.. Something that can do non destructive edits and that can save a jpeg without compressing it so much that image quality is noticably less. Photogene2 is great (nice edit features and good quality saves) but it can't crop or resize exactly by the pixel. Phototoaster is great (nice edit features and non destructive edits) except it can't crop and resize by the pixel. How hard would it be to provide numerical inputs for crops and resizes? Is there anything out there really worth buying that can do these essential tasks?

  • Looking for a high-res drawing app for the iPad

    I've tried a few of the available iPad drawing apps like Sketchbook Pro and Brushes. It's a little hard to tell, because documentation tends to be short on details, but it appears that most of them (with the exception of Brushes) only let you work and export images at 1024 by 768 resolution. That isn't really high enough resolution for professional work.
    Brushes is the only exception I've found. You work on the iPad in Brushes at 1024 by 768, but they have this OS X app that can convert your exported images to a higher res.
    To me that's crazy awkward and time-consuming, and I think Brushes is OK as a drawing app, but not necessarily what I'm looking for.
    Can anyone give me some better insight into the matter?
    Is there some underlying technical reason that all of these apps have a hard limit of 1024 by 768 resolution?
    Is there an app other than Brushes that can produce pro-level (high resolution) image files on the iPad?
    Thanks,

  • Looking for a program or app

    just coming from windows,i dont know if you call them apps or programs? im looking for something that will keep track of customers,money they owe,and money they pay.would be nice if it worked with the calendar and phone book but not necessary.thanks

    You didn't provide the actual name of the Windows program you are using so that features or prices can be compared. What do you expect to pay for a program, or do you want to use an online system that has monthly fees?
    I don't know of any inexpensive programs for the Mac that are specifically set up for Farriers, but there are many database type programs that might be adapted to your needs. GrandTotal, $79 - offers pretty good integration with the Mac Address Book and Calendar (especially if you get it bundled with their TimeLog program for an extra $10) and it also has an iPhone-iPad program that can read open and due invoices you've created with their program.
    You could also take a look at Bento, $49 - from FileMaker, which also has a program for iPhone-iPad. They offer some invoice templates that you can download and modify.
    Both of these companies offer free trials.
    I haven't used either of these products, but I am looking for something with better integration with my iDevices. The Quickbooks Connect program for iPad only works with the Windows version of Quickbooks Pro 2011 and requires a monthly subscription. Windows users are still complaining about it's lack of features so I'll probably pass.
    One of my clients has offered to buy my Quickbooks for Mac, and I might take him up on it if the GrandTotal program works out for me. The program is great, but not very nimble on-the-road.
    Hope this helps.

  • Looking for a cool music app (music creation, recording, playing)

    Hi there,
    I was looking on the app store if there's such application but didn't succeeded at the moment.
    I'm looking for an app that would allow me to create music on the fly with a "midi-keyboard" with which I would record some notes then loop the sample and record a second track.
    And build my simple music by playing bass line, then adding some beat, etc...
    Any idea if it exist?
    thanks in advance

    Please be aware that you are not communicating with Apple when you post in these forums. Most of the people who will reply to your posts are, like me, your fellow users.
    As to your issue, first, make sure that you did not inadvertently make an in-app purchase. Many apps, particularly games, are free for the base game but charge for additional features such as levels, "coins" and other such add-ons. Check your Purchase History to see if that reminds you as to what you might have purchased:
    http://support.apple.com/kb/HT2727
    If you find that this was an in-app purchase, to prevent this from happening again, turn off "In App purchases" in the Restrictions settings on your device. For more information, see:
    http://support.apple.com/kb/HT4213
    As to a refund, that's not automatic since the terms of sale for the iTunes Store state that all sales are final. You can contact the iTunes Store, explain the reason for your request, and ask, though:
    http://www.apple.com/support/itunes/contact.html
    They're usually pretty lenient in the case of inadvertent purchases, but there are no guarantees.
    If the charge was not an in-app purchase that you made and forgot but the charges do appear in your Purchase History, contact the iTunes Store and let them know. You should also immediately change your password for your Apple ID. If the charges don't appear in your Purchase History, they were probably fake charges made directly to your credit card, and your card issuer will need to handle those.
    Regards.
