• A few days, I bought a mac mini which I transferred the data and programs with time machine: programs have been updated except for iMovie, and now it seems that I have to pay for the update: possible? What I am doing wrong?

  A few days ago, I bought a mac mini and I transferred all my data and programs with time machine: all programs have been updated but iMovie (7.1.4)... However, it seems that, to update to the latest version, I have to pay to download on Appstore: is it possible? what I am doing wrong?

  If it were a new mac mini, you need already installed 10.1 iMovie.  Otherwise, but you already have iMovie 9 registered version to your Apple ID, you can upgrade to version 10 for free, but if (as it appears) is an earlier version then you have to buy version 10.

• Help with State Machine user Sequentail events

  I'm trying to create a program using the state machine which include events genreated user to jump between States. Also, I want the program to require a sequence of events to be genreted before entering in some States.

  For example:

  States: Init, idle, a-1, A-2, A-3, B - 1 and stop

  If a-1 State is selected, the user must enter the setting and select the condition A-2.
  The user cannot directly jump without having to access the mode a-1 to A - 2
  If the user selects the a-1 State, he should have the possibility of not input parameter and jump to another State as B-1 or Stop

  State A-3 can be entered automatically by State A-2.

  How to program the machine in order to do what I want? I've updated a sampling program. I'm not sure if I impleted the program properly. The user Panel hangs if I enter State a-1, and then press the Stop button. It does not allow me to leave the a-1 State and forces me to go to State A-2.

  A few other questions:

  -How to initialize all values of boleean to 0 during my Init State?

  -Why is a timeout value?

  Hey there, I developed example of Jacobson on a bit here to illustrate the case "Idle, how far to walk, ' your state machine diagram.

  Some keys on the front panel when you are in the bad condition will do nothing, as you can see, because I only check for buttons, I would like to respond to each State. For example, by pressing "Start on" the State of market won't do anything because this isn't a valid button, but pressing "Quit" will bring you to Idle. To implement the rest of the state machine, it is up to you!

• Design pattern using queues and notifiers and problem with sync

  Hello

  I'm rearchitecturing a 4-channel data acquisition system which includes data acquisition, indexing of data between four channels, signal processing and recording of data.

  All processes are placed in a single loop, and I have subdivided by the following in a producer and consumer two loop (or master with both loops slave), use a queue to manage orders and send the actual data through a notification list. I'm new to this, so I don't know how to go for rearhitecturing but am trying to move several loops. Instead of placing each channel in its own loop, I used only 2 to save duty all architecture. The acquired data are also indexed in the two loops (loop1, loop2):

  Main loop: data acquisition (DAQ Assistant) where Notifier sends data to consumers loops, queue for General commands

  Loop1: bed (table 2D index), addresses and records the data for channels 1 and 2

  Loop2: bed (table 2D index), addresses and records the data for channels 3 and 4

  Question 1: Is it ok to use Notifier and queue in the artchiture (best practices)? I would use two queues, but I find that the program may have a lag (although it lacks all data) and who interrupts the acquisition for the user and I don't want that. I prefer the program to retrieve data in real time and then decided to use the authors of notifications to send data to loops1 & 2. What are the caveats of this? Given that I am gaining at the rate of 1 s/s, maybe it will be enough.

  With respect to the orders queue, this is done and two commands are queued in order to activate loops1 & 2. Using multiple loops slave/consumer, how we manage several channels? the user can choose to acquire all the channels simultaneously or one at a time. I am able to activate the four channels. In this case, because loops can not run in order, how do you ensure that the item is read by the right loop?

  I'm running into a few problems:
  Question 2: synchronizing data - use 'wait on ms' synchronize all loops (main loop and loop1, loop2)
  -data doesn't seem to be very good sync - why is - this? consumer of treatment<>
  -what I'm missing?
  Question 3: processing loss data - because using filers is frozen and using queues is not, I did so that orders of the so-called 'turn on' the two loops is done using a queue. I compared it with the notifiers
  Question 4: Errors - I made loops 1 & 2 output on the notifier error error - they throw an error when the program stops so happy so I was testing for. I read some ni.forums he's talking about is enough, but what are the other types of error monitoring (error reporting)? Thank you very much for reading!

  I programmed so far and it can read all or individual channels but I want check against all cases, that's why I ask these questions to check. I know that architecture may not be the best, so any suggestions would be welcome. I try to get the synchronization of the time and I don't want any data with loss. I guess that the use of queues to send data and commands is ok?

  Thank you in advance for your help!

  
  

• Tokens signature and debug with multiple machines

  There has been various issues and discussions on the backup for signing keys.  This thread says you can save your P12, CSK and DB files and then use them on another computer if your original dev machine never dies.  But I'm confused about how actually to 'install' these files to a new machine (with Flash Builder).  Does anyone have this done successfully?

  I have a second machine where I'm trying to restore my certificates saved (as a test).  I pulled FB on my P12 file, but I don't see anywhere to point to my a CSK or DB files.  The 'power of signature of register with RIM' command looks like that it just creates a new CSK, which broke app update.

  Registration also requires a file of the LSB, and those who are not supposed to be reusable.  The only way I know to get another file CSJ is to complete the shape of the RIM to request a whole new signing key.  But still, I don't want a new key signature...  I also wonder if it would be 'disable' the possibility of signing of my original machine - that is to say, each provider may have only one machine registered for signature at a time?

  A related question: has any who successfully put in place several machines dev (do not sign machines) with chips of work debugging?  FB doesn't let me create a debugging token until it is registered with signing authority, which once again the SJC prescription problem I mentioned above.  And it wont let me point to an existing BAR token I created on a different machine - even if the RIM docs say "you can distribute the debugging tokens you create for developers."

  So, anyone who has ha the chance with this kind of dev multi-machine configurations?  Details on how to do it?

  Thanks in advance!

  There was a problem with the BlackBerry Tablet SDK where the debugging token button import has been disabled until you have saved the code signing key.  This problem has been fixed in the latest version.  You can now import a token of debugging without keys of your choice.

• Combine results of 2 motions, one of them using Group by and a WITH statement

  Hello world

  I am trying to find a way to combine the results of 2 queries (Oracle 11 g). The first query was a select simple, something like:

  SELECT A.ACTDAT, A.ENDDAT, A.ITMCOD, B.ITMDSC, A.PRDORD, A.FPQTY, A.FPACT
  FROM Table1 A, Table2 B WHERE A.ITMCOD=B.ITMCOD AND A.VERNUM='VM10' ORDER BY A.PRDORD;
  

  The second query is not so "simple", but:

  WITH Tab1 (ProdOrd,Pdate)
        AS (SELECT T.PRDORD, TO_CHAR(T.SYSDAT, 'MM-DD-RR HH24:MI') FROM Table3 T,
  Table4 I, Table5 D, Table6 E
  WHERE I.ITMCLS = D.ITMCLS AND I.ITMCOD = D.ITMCOD
  AND D.DTLTYP = 'F' AND D.TRNSEQ = T.TRNSEQ
  AND T.TRNTYP = 'LINTAK'
  AND D.LOCATN = '10'
  AND E.PRDORD IN (SELECT PRDORD FROM PRDQUE WHERE VERNUM='VM10') 
  )
  SELECT MIN(Pdate) "1er LINTAK", MAX(Pdate) "Ult. LINTAK" FROM Tab1
  GROUP BY ProdOrd
  ORDER BY ProdOrd;
  

  For each A.PRDORD in #1 query, the second query should return the

  MAX(Pdate)
  

  as follows:

  A.ACDAT (from #1 query)	A.ENDAT (from #1 query)	A.ITMCOD (from #1 query)	B.ITMDSC (from #1 query)	A.PRDORD (from #1 query)	A.FPQTY (from #1 query)	A.FPACT (from #1 query)	Min (pdate) (from query #2)	Max (pdate) (from query #2)

  While separately, both queries return the following results:

  Query #1:

  
  

  A.ACDAT (from #1 query)	A.ENDAT (from #1 query)	A.ITMCOD (from #1 query)	B.ITMDSC (from #1 query)	A.PRDORD (from #1 query)	A.FPQTY (from #1 query)	A.FPACT (from #1 query)

  Post a small example of data (CREATE TABLE and INSERT for all involved tables, the columns only statements) and the results desired from these data.

  See the FAQ forum: https://forums.oracle.com/message/9362002

  You want to include the lines of table2 who lines returned in the other tables.  This sounds like the job for an outer join.

  You want to ignore the dates on some lines.  That wound like a job for a CASE expression (or if-then-else function specialized, like NVL2).

• Closure of a state machine in queue event with several parallel loops

  I am trying to find the best way to stop a program that consists of an architecture of State machine in line waiting for event with several parallel loops. Can anyone recommend the best way to achieve this in my attached VI? (To browse the forum, this seems to be a frequently asked question, but I have not found a solution that works for me.)

  I look forward to any comments on my as well code, if someone is willing to offer it.

  My program needs:

  If the user press the 'Stop' button, the program should prompt the user with "are you sure you want to stop the program?" and then return to a State of rest or move forward to stop the program. In addition if there is an error, the program should prompt the user to ' clear the error and continue, or stop the program. Then back to the idle state or move forward to stop the program.

  Architectural details:

  The program consists of 3 parallel loops: (1) a loop of event management that places different States of a queue of the State, (2) a State Machine that enters the State that is removed from the queue of the State and (3) a loop error/Shutdown, which deals with errors in the error queue management.

  During normal shutdown, where running handling loop in the case of event 'Program.Shutdown' and 'Shutdown' and the 'Idle' States are added to the queue of the State. In the state machine, the State of 'Stop' is invoked. Special "5000" error code is added to the queue of the error. In the loop of error handling and stopping, "5000" error triggered a prompt that asks the user if they want to stop the program. If the user chooses not to stop, a notifier StopNotif is sent to the State of 'Stop' and 'Program.Shutdown' event case with notification 'Go '. If the user decides to stop, the Notifier sends the notification "Stop". Loop and event management State Machine ends when they receive the notification "Stop".

  In case of error, the program behaves in the same way: If the user chooses to clear the error and continue, the program returns to the status "pending".

  HOWEVER - if the user chooses to stop the program, the program crashes. The author of the notification that is sent to stop the loop of events and State Machine management cannot be read because event Program.Shutdown and the stop State (which contain the function "Waiting to notify") are not active.

  I was able to activate the stop State by Queuing in the loop of error/Shutdown management. But I don't know how to activate the "Program.Shutdown" event by program and thus access the function "Waiting to notify" inside.

  I tried to put the function "Waiting to notify" outside the structure of the event, so the event-handling loop never ends. Placing timeouts on the "wait for declaring" and the structure of the event makes the programme of work, but I want to avoid using timeouts because I don't want to turn my event program into a program of polling stations. I would also avoid using variables or nodes property to stop loops, because that requires the creation of a control/indicator for something that the user does not need to interact with.

  Thank you!

  First of all, close the notifier outside loops with your queues.  Second, you must use a user event to send the message to the event structure loop so that it stop in the case of the stop on an error.

• standard with a state machine controls

  Hello

  I read with VISA to a serial device. I am writing for the series the start character and the device sends data.

  Now after reading the data, I want to stop sending in writing to the series a stop character. Separate loop is playing.

  I want to do a stop button that written in the series and a start button that writes serial and bed data. Is it possible to do without a state machine?

  BTW, are there examples for a series of reading and writing of State machine?

  This has proved to be a bit more complicated as I first thought.  If I wrote you a demo.  Just add your series writing and reading the code when indicated.

  It is not a state machine.  It looks more like a producer-consumer architecture.  Product event loop start and stop commands.  The other loop is executed according to the orders.  The trick was to get the series reading loop so that it could be stopped at any time and restarted at any time.

• channel state machine does not

  I have a producer/consumer architecture and problems with the machine States recognizing the new State.

  According the probe, when the structure of the event fires, the entry in the case selector is:

  "HV OFF."

  "

  (with the carriage return), but the case is called 'HV OFF. "

  My strings are combined into an array with the array of build function.

  A State does not work properly, and the probe indicates the State in the case selector is "serial number", with the final on the same quote line.

  If someone has encountered this?

  Go to each string constant, right-click and do show slash codes "-codes.  Now, you see the character, not a carriage return, character jump extra which is actually a line and can remove it.  (You can delete it in normal view as well, this is, you it's just more complicated than it is because it is not really.

  To do with a typedef enum, create a control of the Enum.  Change the elements and type in all the States you want.  Right-click on the control and customize it.  Choose Type Def as the type of control in the toolbar.  Save the control as a .ctl file and let it return to the regular window of LabVIEW.  Now you just use a copy of the control, or a constant created from the control.  You can not accidentally type something wrong because you have an enumerated list, you can choose from.  If you need to add another case, edit the .ctl file and add another element to the control of the enum.  Now all of this constant or control instances that refer to the typedef file are updated automatically.

  Your currently implemented in a string to function statemachine is little involved.  You are working with a queue, but each item in the queue is also a table.  If you are made a table, browsing, then when you're done, he could catch the element next to the table 1 d.  Except in your implementation, you have nothing stopping inside while loop because you never have a real associated with the Terminal stop.

  With enums, you do are enqueue each each enum.  If you wrap the element of queue with a loop for and feed a table of enums, so it will enqueue each step in the order.  The loop of the producer will be dequeue each step in order, and you don't need this inner while loop that you currently use to autoindex your array of strings.

• Need help with the events of user base in state machine example in queue

  I wrote a small example queue state machine to try to teach myself about the creation and use of the user events.  The purpose of the machine is periodically pick a number (I do now with a control instead of a generator of random numbers for troubleshooting), and compare this figure with the number I put in a control.  When they match, I want to raise an event to fire so I can do something about having found a match.  The examples in the file LV references help show events within the structure of the event, but I want to reach out of a State and trigger an event...

  Can someone point me in the right direction here?

  Thank you

  I think the service you're looking for is generating the user event.  What to put in your consumer loop, inside the case structure when identical numbers.

• State Machine with queues

  Probably a stupid question, but if I'm not asking that I not just guess.

  I have a well-organized State Machine and I am in the final stage - data record. The saved data might be pretty long (a good 15-20 seconds) due to the latency on our LAN and I think that the best way to address this would be to use queues. I was wondering what things I need to look out for or is it as simple as pass the data to the consumer?

  I would need just two pieces (a field ID and its actual data - two string values) of data for each record that could be transmitted through a 2D array.

  Sounds like a normal of the producer/consumer for me.

• State machine with acquisition different modes/loops

  Hi all

  I did a machine design to State (as described here) to organize three (mutually exclusive) process / States: idle, measurement of calibration and continuous measurement. Calibration must be performed before measurement, because the result of the calibration is used for measurement. The data entry is a camera that should run continuously, also in rest mode.

  The problem however is that this state of calibration and continuous measurement (should) have another method of data acquisition. The measure is continuous and the images are processed in real time. To calibrate a number N of images should be accumulated and treated (simply create a background image).

  In the state machine as I have now (see attached image), I have the acquisition of vision outside the state machine in order to have a live view at any time. The problem now is that the inner loop in the State of calibration (the loop that must accumulate the framework) accumulates of course that the first framework N times, it is not question for all new managers during this State.

  Of course, I could fix this with an if/else statement in the first calibration mode accumulate images (if I< n,="" accumulate="" frame="" in="" buffer="" and="" continue),="" but="" i="" am="" not="" convinced="" that="" having="" a="" lot="" of nested="" loops="" is="" the most="" elegant="" way="" to="" do="">

  This also got me thinking, is the state machine, as I built it here all the best way to manage these two processes/acquisition modes? Or are there better ways to do this?

  Contributions and comments are very much appreciated!

  Note: I know that loop as scheduled now in State calibration is wrong with shift registers. It was a test before I realized that the fault was in the interweaving of the state machine altogether.

  Please do not attach pictures, but rather post executable code, screws (easier) or as extracts from LabVIEW (which became the screw when you drag in a block diagram).  If you have more than three attachments, compress the folder and attach the ZIP file.

  I was once describing a system similar to yours, and one of my students, who was a computer science major, said "it's not a State Machine."  I had a similar situation to yours, where I had a procurement process which took time and a 'Stateful' routine that does different things with data (in your case, use it for calibration, waiting to 'Go', absorbent, etc.).

  I understood that it was correct.  I ' D 'opposite' model, with the Acquisition, always running and "driving", the calendar and make 'Appropriate Action' on each set of data, where the Action could (and did) vary according to other conditions.  So I renamed my state machine 'Action engine', and everyone was happy.

  So I won't bother looking at your code (a quick glance showed me that I have only would be frustrated by the limited view), but will give you a suggestion for an alternative architecture.

  You want to (ideally) two parallel loops.  A single loop simply acquires the data (images) at some rate.  For each Image, it signals the loop else it's time to 'Action' on the acquired data (to do this, use a queue or the notifier).  You want that engine of the Action to perform independently the Acquisition loop, just in case a particular Action takes, say, 1.2 times sample to complete - you don't want 'Miss' samples!.

  The loop of the engine of the Action is a unique, appropriate Action at the time, on the newly acquired data.  If you are in the 'State' calibration, the Action will be "add to the calibration.  When you have accumulated enough data to do calibration, set the following Action to (for example) 'wait to start the Signal.  When you receive the Signal to begin, take Action to "acquire, process and save data.  And so on.

  As it happens, I did my code exactly in this way, but it was the idea General - Acquisition was the 'King', he ran the clock and led the ' Machine/Action State engine' to 'do the right thing, appropriate to the time' with the data.  See if this type of model is appropriate in your situation.

• event and state machine

  Hello

  I have a problem when I want to set up an event in my state machine.

  The state machine is reading communication series through different States 10 +.

  The problem came when I tried to add an event inside the State number 10. In the number of State 9 code seems to work only partially (an option button is not possible to change the value on).

  It seems almost that it is frozen but when I select the code I can see it works well (option button isn't).

  It is strange that when I remove the event in condition 10 all is well again? The event code is not yet performed yet because it is in the frame after!

  Any thoughts?

  I'm under LabView 2013 on a Windows 7 PC.

  I'm trying to figure out which of the two cases is the one who seems to hang if the name would be better than a number.

  When using am event structure you don't we want to use a local variable.  In fact, you should only use local variables on rare occasions that they break the flow of data.  The event structure is fine for the entry.  The problem is the way you treat things after that the button is pressed.  Again, I think you have to look at a design model of producer/consumer with a machine of the State in queue.

  The best way to have a writing occur only after a button must have the code for writing in a case that is active when the button is true and is simply empty, when it has the value false.
