• The function of enter the characters of left, right or middle of the member name?

  Does anyone know of a function or set of functions I can use to enter characters in a member name in a similar way to the functions of Excel RIGHT, LEFT, or MID? I would like to be able to write a rule to retrieve only certain characters in a member name.

  Hello

  If you look briefly into the ref of technology so you can find @SUBSTRING (String StartPosition [, EndPosition])

  StartPosition

  Beginning at the character position in a string to be included in the substring. An integer greater than or equal to 0, where 0 is the first character in the string, 1 corresponds to the second character and so forth.

  Final position

  As an option. An integer greater than or equal to 1, where 1 corresponds to the first character in the string, 2 corresponds to the second character and so forth. If the end position is not specified or is less than StartPosition, Essbase returns all other characters in the source string. Note that this is a different numbering scheme that uses the starting position.

  Now, I hope you have a good naming convention.

  Kind regards

• The queue function seems to replace the values

  Hello

  I work with a PCIe-1473 Framegrabber to get pictures of my build-up by 8192 pixels camera Basler.
  When you play for the FPGA, I use a host DMA. After reading in a while loop, I put my vectors to pixels in a queue and I use a second while loop to process the data. I'll put my queue size to 10000 elements. After a while, it seems that the treatment does not work properly and I get a picture that is repeated, as shown in the included images. A person never had such a problem and if so any idea how to solve this problem?
  Thank you much in advance.

  Kind regards

• How to set an expression by the range of values & run function value entered

  I'm looking for help with an IF statement that focuses on value ranges and executes a sum based on what it finds.
  I use LC D 8, the script runs on FormCalc - Client-side - calculate events. Numericfield1 is a value entered by the user.

  I currently have (which does not work):

  If (numericfield1 > = 1000 < = 4999) then / / I want to check is the power of users lies between these figures

  numericfield1 * 5 / 1000 / / if I want to run this sum only

  else if (numericfield1 > = 5000 < = 9999) then

  numericfield1 * 10 / 1000

  else if (numericfield1 > = 10000 < = 19999) then

  numericfield * 20 / 1000

  endif

  So if I get 2500 in numericfield1 the sum would be: 2500 * 5 / 1000 = 12.5

  I want to keep these ranges of values in these games: 1000 to 4999 | 5000 to 9999 | 10000 to 19999. 20000 to 49999. 50000 to 250000.

  (here also to enforce that 1000 is the lowest possible entry)

  The above work when numericfield1 is anything below 4999, but anything after that he continues to * by 5 then / 1000. Where there should * 10 / per 1000.

  Hope someone can push my thinking in the right direction, thanks in advance.

  You need an "and" in your statement:

  If (numericfield1 > = 1000 and numericfield1)<= 4999)="">

• Queue RAS does not work with "Key relachΘe".

  Hello

  probably just a simple thing I'm missing here. See the VI attached (including the Subvi). In case 1, I get the event button Up to ENTER and deliver a change in value on the Stop button. This translates into a verification of the length of the string, and where she is too short made up a dialog telling you the ID is too short and takes you back to the entry ID unfortunately - upon confirmation of the dialog with the ENTRY instead of using the mouse on the button sequence an event triggered again and then read by the Structure of the event.

  So I thought I just rinse all the events in the queue. To be sure, I put a time value on the service of hunting that takes place AFTER the dialog box is complete, so the key place ENTRY should be deleted as well. Jinx is - it does not work. Someone knows why?

  I tried both with the dynamic event, I have not registered right after that the stop event is issued in the case button upward. I then "re" sign for the key event to the top at the same time/position that hunting event queue function is now positioned in the VI below. Still no joy.

  What was my mistake? Thank you very much.

  Comrade wrote:

  I don't understand 2 things:

  (a) why the key, an event is triggered even? It does not come from the VI where the structure of the event and what 'Instance', the event is bound (VI-> up key), but from the dialog box (which is an another VI). Unless a call VI inherits all the events of his SubVIs or something like that.

  (b) why isn't the event raised by the button in the dialog thrown as hunting event queue function is supposed to run?

  Because you're slow.  Not you personally.  But compared to the computer, you just don't have a chance.  If you hit the button Enter on the dialog box.  OK button on this dialog box activates the button down.  If the dialog box is long gone by the time you manage to get your finger on the Enter key.  In fact, you loop must be around back to wait first for an event.  So he is waiting for an event when you finally get your finger on the button.  Hey, we have a key event to the top!

  Your current checking for the validity of the id is just boring hard.  Use the key down? event to check a valid character entered.  Notice the '?' in my choice of event there?  This means that it is an event of the filter.  This means that you can throw (throw) the character being pressed before that same control sees it.  You might also throw if there is already enough characters (greater than or equal, does not).

• How can I switch changing values to a single channel with a matrix or a queue?

  Hello

  I need to move from an evolution of digital signals (e.g. acute-low-low-high... where a new signal would come to each clock cycle) to a single output port. I also need to enter the desired first wave (preferrebly in the form of 1001).

  There are several ways to do this - I tried to play with the spi and the queue functions, but could not get to work.

  Right now I use a one-dimensional array of bool to get entry. I then pop the first element of the array and write it in my DAQmx (it's essentially a queue). I put this in a loop such that it would go until the array is empty, but for some reason, it is just the first element. It is not moving to others...

  It's my first time with labview for explanations are greatly appreciated.

  I have attached a picture of what I have so far... It is important to note that I'm finally at the entrance of the 32-bit binary strings that is why my block diagram is a bit funny. In addition, tables 2 and 3 are not something special - they are indicators.

  Of course not.  You do not update the table.  Even in this case, I think that what you really want to do here is has to loop so you can autoindex on the table.

• Key 'Enter' MacBook

  My new MacBook nice 12 "has two symbols on the Enter key - the usual arrow at the top, but also a line above a point of support below.

  Is the second symbol linked to a second function of the button - I can't find any info on it anywhere?

  

  The key has two 'functions' - return + enter. To use 'Enter' key press and hold the function selection [fn] and press [return].

  Discussion about it here: http://apple.stackexchange.com/questions/47565/return-vs-enter

• How to build an application to queue?

  I want to apply for the queue using labview. If I have a list of data, for example 100,200,300,400,500,600 and 700 stored on table or matrix, and then using a queue function it process the data one by one after each other. How I do that? I'm using labview 2009 and 2010.

• passage of queue to dynamically called VI

  In my application, I have two screws. IIn a VI I create a queue and then I spend the Ref. of the queue for the other VI and launch this VI dynamically.

  While running any VI can stop regardless of the status of the other VI.

  but as soon as I stop the VI who created the queue. the Ref. of the queue becomes invalid. and dynamic VI cannot use the queue more

  I want to the queue to be eliminated that after I explicitly call has queue function.

  How can I achieve that

  Hey Tushar,

  You can create a "functional Global ' which encapsulates the function Create tail and buffer the reference to the queue in a registry to offset.  The VI may have two modes of operation: CreateQueue and ReadReference.  The top-level VI he would run in Design Mode, and the VI dynamically saying would just continue to use the playback mode.  Since this VI remains a VI performance left even after the parent process ends, the queue reference, allocations will remain valid.

  See you soon!

• Buffer could replace the queue in the design of producer/consumer model

  Hello

  I have a question to which the task of buffer to store the data and the queue is also of the same thing so we could use the inplace queue buffer in a design of producer/consumer model.

  No, these examples of buffer not almost equal to a queue, and never "replaces" queue at the producer/consumer.

  The advantage the most important of the queues for the producers/consumers (which none of the other mechanics buffer sharing), it is that it works activities to warn the reader that the data is available. So if you would simply replace the queue by mechanics of tampon too developed that you have attached to your last post, you will lose a large part of the object using producer/consumer.

  Thus, to compare the two mechanics:

  -Tail works activities, while the example of the buffer is not.

  -Tail must allocate memory during execution if several items are written in that corresponding queue. This also applies to the buffer (must be resized).

  -Given that the buffer is actually simply a table with overhead, memory management becomes slow and messy with the increase in fragmentation of memory. Queues to play much better here (but have their limitations, there also).

  -Overload of the buffer (the table manipulation) must be implemented manually. The queue functions encapsulate all the necessary features that you will need. So the queues have a simple API, while the buffer is not.

  -Given that the buffer is simply a table, you will have a hard time sharing the content in two parallel running loops. You will need to implement an additional charge using data value references to manage the buffer or lose a lot of memory using mechanics as variables. Lose the memory, you will probably encounter racing conditions so don't think not even on this subject.

  This led to four '+' for the queue and only a single point where 'buffer' is equal to the queue.

  Hopefully, this clears things up a bit.

• Why would I have a queue in two different vi generate a sepearte refnum, if they have the same name?

  Hello world!

  I have a producer consumer configuration, where the producer and the consumer are in sepearte vi.  They have the same name, but do not communicate their existence to the other for getting queue function.  Therefore, only one is valid, the other ends up invalid.  If I check the renum for each loop, they are different.  Assumptions?

  Destory queue has been wired for real in the Subvi, force to destroy the queues.  Thus, the queue was invalidated and then recreated in the other vi.

• "Change plan settings" opens whenever I click on enter

  I made the mistake of letting my little 1 year old daughter plan with my computer for about a minute.  Now every time I press Enter a window with the following path appears:

  Control Panel > power options > change plan settings

  Help!

  You have a programmable keyboard?  She could have accidentally reset ENTER to redirect to this location.  If so, it's just to reset the keyboard to factory settings (but's done it according to the manual - it varies depending on the make and model) and you should be fine.

  If it does not or is not the case, see this article on the remapping of keys: http://vlaurie.com/computers2/Articles/remap-keyboard.htm.  I don't know if the program can be used with only a mouse (or without the Enter key), but it is possible.  I am sure that the problem can be corrected in the registry if you can get there (even if I have to be honest and say that I don't know how to do that, or rather that the entry refers to the Enter key).  To do these two steps, try to start in safe mode with networking (hit F8 continuously during booting until the menu and see if the enter button is working.  That would be great.

  If that is not the problem or does not solve the problem (perhaps because the Enter key still does not work in full safe mode) then try a system restore to a point in time BEFORE the problem started (I suspect it's probably where you actually have to start because I'm not sure of the keyboard mapping program or soft keyboard).  Here is the procedure: http://www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/.  Don't forget to check the box to show more than 5 days of restore points.  If the first attempt fails, then try an earlier point or two.  NOTE: You will need to re - install any software and updates that you have installed between now and the restore point, but you can use Windows Update for updates.  You may need to use the CD to do if F8 does not press enter. How to start the CD are described below.  I hope that the button functions correctly enter this mode, because it will be VERY difficult to do any troubleshooting without it.  All the keys she might have reset, it was certainly the worst.

  If the system restore does not work, do a startup repair, boot from the disk Installation of Windows Vista genuine (or one that you can borrow from someone) or a recovery disc.  Here is the procedure: http://www.bleepingcomputer.com/tutorials/tutorial148.html.  You may need to change the BIOS to do first the CD drive in the boot sequence to boot from the CD.  To do this, hold the screen that tells you the key F to push to enter the menu start or start of installation.  Push it quickly. Make the changes, save your work and exit.  Put the CD in the drive and reboot.  When you are prompted, press any key to boot from the CD.

  If you do not have a floppy disk, you can make a bootable recovery disk by using http://neosmart.net/blog/2008/windows-vista-recovery-disc-download/ with burning software like: http://www.snapfiles.com/get/active-isoburner.html and, of course, a blank CD.

  If this does not work, try to start in safe mode (repeatedly hit F8 key so that the start and go in safe mode with networking).  Then we will check some of your system files:

  Go to start / all programs / accessories / command prompt and right click on command prompt, and then click Run as administrator.

  Type sfc/scannow, go and let it run.  It will scan and try to correct some of your system files.  If all goes well it will complete with no corruption, he couldn't fix it (if there is such corrouption post here or try to analyze it to find the problem or files using http://support.microsoft.com/kb/928228.

  If this does not work, you will need to do a repair/system upgrade using the Windows Vista Installation disc authentic (you own or that you can borrow from someone).  Here is the procedure: http://www.vistax64.com/tutorials/88236-repair-install-vista.html as well as the upgrade from an earlier version of the Windows section of the following: http://support.microsoft.com/kb/918884.  Although this will not affect your data, settings or programs, you should always back up your data before you start just be on the safe side.  I don't like this goes away from doing just that a 1 years within 1 minute, but to be honest I don't know how to do what she does if I had hours of research on problems - it will be interesting to see how it works for later reference (although I am sure that you feel completely different now).

  I hope one of these procedures can solve your problem (probably the system restore or repair/upgrade system).  If this isn't the case, after return and we will try something else.  Return message anyway so we know how it turns out.  You have me very curious at this stage.

  Good luck! Lorien - a - MCSE/MCSA/network + / A +.
