• Global variable to capture the username with Form 6i

  Hello world
  I have a menu created with Forms 6i and the shortcut that I use to call the menu in its target the following: C:\orant\BIN\ifrun60. EXE userid = name of user and password MYFORM. FMX
  When I remove the user name and password of the target of the shortcut he asks me the user name and password so when I typed, I am authorized to enter the application, but I want to be able to store the username on a global variable and set the value on an item when the user selects the program that he or she wants to use , so they're not going to see the other users information.
  Can someone please help me to do this step by step?
  
  Thanks in advance!

  Try: SOULEYMANE. VARIABLE: = USER;

  The USER is a function that returns the user name, as SYSDATE returns the date.

• deploy programmatically variable shared within the standalone version of RT (cRIO-9014)

  Hello

  I have a question about here to use variables shared single process within the standalone version of RT for the cRIO-9014

  I simplified my request of LV (LV2010) in two to test the use of shared variables.  See the attached file.

  (1) only run on the host PC: testHost
  (2) only works on the cRIO-9014: testRTcRIO

  for both, I packed stand-alone executable and source distribution.

  for testHost,.
  (a). I copied \builds\testcRIO\Host to d:/or-rt/xmlrpcFEU source Distribution...
  (b) I run... \builds\testcRIO\Host.exe
  (c) xmlrpcFEUlog - host.txt is generated.

  for testRTcRIO,.
  (a) .d FileZilla to connect to the target of RT on network, I copied... \builds\testcRIO\Source Distribution\c\ni - rt\xmlrpcFEU

  to/or-rt/xmlrpcFEU on the target of RT
  (b) I copied also... \builds\testcRIO\Real-Time Application\c\ni - rt\startup to/or-rt/startup on the target of RT
  (c) Max, I restarted the cRIO-9014.
  (d) xmlrpcFEUlog - RT.txt is generated.

  We see that the shared variable does not work inside the RT target. but worked well on PC. the deployment programmatically method does not work.  any suggestion?

  Another thing is:
  can I use telnet for the RT 9014 target and start the RT app directly? What is the command inside the terminal telnet RT?

  Currently, I can telnet into the cRIO-9014, but, what I can do with it?

• Can I use a global variable to determine the event?

  If I want to switch using MouseEvents or TouchEvents, can I use a global variable to switch between the two?

  For example,.

  var myEvent:String = new String();

  myEvent = "MouseEvent.MOUSE_UP."

  myEvent = "TouchEvent.TOUCH_TAP";

  myObject.addEventListener (myEvent, doFunction);

  This does not work, but I was wondering if there was a good way to achieve this so that I can switch between the modes of entry easily during the test across different devices?

  do not use quotation marks:

  var myEvent:String;

  myEvent = MouseEvent.MOUSE_UP;

  myEvent = TouchEvent.TOUCH_TAP;

  myObject.addEventListener (myEvent, doFunction);

• Chart "sets" inside the symbols

  the search here, and Googling for how it creates sets of graphics in a single symbol, has been fruitless so far.

  One of the tutorials online and David Stillers HERE

  Illustrates the use of several graphics games stored within a single symbol and how to access.  There is however no comments on how to create them.  Probably not necessary for intermediate or advanced user, but for me to be really new... his apparent not all how cela is done.

  I want to create the illusion of a mule walk by fiddling with the legs in a set of graphics and then we hope to animate.

  It seems that I could put in a single symbol as shown in the video above and access as described here.

  There may be better... but in any case I still want to know how to put multiple versions of a Graphic in a single symbol.

  What do you mean how to create? You created them. You can make a new graphic and then draw the work giving each version of the game with its own keyframe.

  Then where it shows the mouth about 4 minutes. You create a new graphic symbol, cutting one of the mouths and stick it on the timeline. You can make a new blank Keyframe, will copy the next mouth and stick it on this picture and so on. You are then the nested graph it shows about 5 minutes.

  BTW, this technique is the best thing I've ever learned about animation in Flash.

• Start time set for the symbols on the timeline?

  Hello

  I've built several buttons - like symbols - that animate on screen and wants to shift departure times a little effect.

  I thought I'd be able to simply drag the symbols on the stage and set hours of departure by clicking on and dragging them on the timeline, but that doesn't seem to work. I see the 'read' and a + button but regardless of what I try, I can't seem to delay the start of the symbol.

  Any ideas?

  Thank you very much, I am stuck between the old Flash programming, development of Captivate and After Effects... Phew!

  Hi Richard,

  I created a simple example for you. Check if it's how you want to play the animation.

  Thank you and best regards,

• Global variable in the progress bar

  I have an existing labview code that consists of a main vi, which is the GUI user, and several (about 70) under vi. I am trying to add a progress bar on the screen before (user GUI) which will be immediately after it hits certain sections of code. I write this using a global variable to store the value of the status and any attempt in the main on-screen progress bar after each increment. Is there a way to link the main progress bar value to the global variable so that it updates as soon as the value is incremented? The problem that I am facing is that when I update the global variable in a Subvi, the progress bar takes the value of the Sub - VI is finished, all the numbers to jump between the two. I know it's because I do not correctly write to the progress bar, but I don't know how to do. If this isn't a good method, are there any suggestions?

  For example:

  SubVi2 SubVi1 Vi main

  (1-4)                (5-8)             (8-12)

  Progress bar: 1 2 3 4 8 12

  (I tried the Progress Bar Library OR offer, but I need a progress bar on the front panel, not a sound upward, so I can debug for code execution)

  Thank you - Adam

  I would go with a motor of Action update the progress bar VIA referance Server vi.  Here is an example of the use of a side effect I have to make this kind of progress bar.

  If you have not read Ben nugget of action engine, it should be mandatory, you can find here

  By building a "resource module" (a special AE that keeps a referance to the resource to act on) after initializint EI, you can call any 'method' on the resorce from anywhere in the instance of the application.  These babys really allow you to do interesting things to the GUI from around where the real action takes place.

• With the help of semaphore with a Global Variable - correct use?

  Hi all

  I looked in the use of global variables and in my case, it seemed with the help of a semaphore is the appropriate solution.

  In my case, I use a global variable to store the State of the system. Asynchronous two with screw environment (same VI) will follow two COM ports to see if they get a ' login:' command prompt. If the COM port is associated with Alpha, Charlie, or Echo, it increments by 1, and if it is associated with the Bravo, Delta, or Foxtrot, is incremented by 2 GV. If the GV is 3, the rest of the code will run. In this case, it must be a port COM A, C or E; the other should be B, D or F.

  A VI parent is called inside a loop. He works for the first loop. He never adds up to 3 on the second loop, however. I can't understand why. Please let me know if my code is a poor use of semaphores, or if there is debugging I can try.

  I'm still relatively new to LV, so I'm sorry if my screws are difficult to read. I created this in LV2011.

  Thanks for any help!

  The output of my time looping (wait GV = 3) goes to the structure of the case on the bottom right (clear SGS, PasswordEntry, etc.), so the GV get indeed consulted by the upper case structure right.

  ??

  Your right upper case structure does not run until your time ends in a loop.  The while loop does not stop until the total is equal to 3.  Where can increment you the world besides structures case you cannot yet?

  Have you tried in your point culminating execution of the VI in order to see how they are actually running?

  Another problem that I see.  Assuming that your first while the loop is going to end.  In the structures of your case, you lock the semaphore.  But you can never unlock the semaphore unless you have the right combination of conditions that allow you to get to the case that unlocks the semaphore.  The conditions are based on data that are read before the start of the case of structure, which means that data will not be read and changed until it all ends.  You have the timeout of your lock semaphore connected on one of the cases, but your semaphore lock can never timeout because you do not have a value on his entry time-out.  I think you have a situation where you can lock a semaphore, then arrive at a situation where you can not unlock, then wind locking up of your cold code.

  I don't really think that you need a semaphore at all.  I think you can protect reading and writing functional your overall using a global variable, i.e. the motor action.  Overall, I think you need to rethink the architecture of your code.

• Create the global variable

  I am new to animate. Please can you tell me how I can declare a global variable?

  I try to have a single button that plays the next 10 frames, another button that plays the next 20 images. I put the event listeners for the buttons on the first image. I'm putting the code on the timeline each 10 images that works if the game has to stop. I would like to connect with some global Boolean values. The project is the html canvas.

  It must be simple. Can you help me?

  Scope of variables in canvas mode:

  myVar = 1; variable is accessible everywhere in the current page

  this.myVar = 1; variable is accessible in all the images of the current clip

  var myVar = 1; variable is accessible in the current context only

  So yes, the creation of a global variable is simple the most.

• I don't get to use the global variable. Take a look in my form, please.

  Hello.

  I'm ashamed. I'm not able to use a base on the LiveCyle feature: Global Variable / object.

  I have a textfield for the user to put your name. Then, the user must click at the base. His name and value must be of value to a global variable, then I would use this value in any form.

  This look at my example I would use this value.

  https://Acrobat.com/#d=k0YlC1MXEdVTh1g2TXAJxw

  What is the error? I tried to put as a global variable, but it does not work.

  PS: Call of the value using textfield (TextField.rawValue = TextField2.rawValue), it works fine, but I prefer to use the variable

  Thank you very much.

  Hi Rafael,.

  I'm good thanks

  I do not know if I understood the question, but I think you're asking if it is possible to have a field that displays the value of a global variable (i.e. the 'view' you refer to), which is updated automatically via scripts of calculation or similar to but not dependent on another event, such as 'click '.

  In my view, using a linked across the object world is the only way, and you are right - it is certainly easier.

  Please let me know if I've not understood the question

  Thank you

• Code reuse within the same VI (when he's not a Subvi)

  My last question here was awarded a point congratulations "to have been a big question", which is quite annoying, because my current skill level, it is hard to imagine the time when I will never be anything other than a "taker" of this forum!  So this is with a "dumb" question to try to put the right folder.

  My front panel has 17 groups of one button + three numerical indicators, it's quite a few elements of façade and 8 groups have an enum indicator as well.  All of these are also controlled by the visibility property nodes or 'off '.

  My program gathers all data for these elements in a table at the end of the main loop and functional global variables, it refreshes the properties and values of all these elements of façade.  It might sound like undisciplined, but because of the similarity between the 17 groups that refresh the elements panel above all happens within a pure FOR loop (albeit with a structure AFFAIR of 17 channels inside) if these controls are at least not sprawled all over my block diagram.

  The only problem I have is that my program takes a few seconds to initialize and get the loop running, period during which the façade shows garbage (well, maybe not garbage, data maybe related to the last time the program was executed, which may have been a context different, so much better if not visible).

  But if I also ran the same right 'before the code refresh of the Panel"after initialization (wipe) the data in my functional overall, the result would be that all of these controls would be invisible or disabled, which is a much better place to start from.

  But what I need to put a copy completely separated from the loop on my block diagram to get this effect?

  Make a sub - VI is out of the question, because it's the front of this VI that I'm working on.

  The word that describes what I want to do (for me) is "subroutine", but in LabVIEW "subroutine" seems to have a very specific meaning, a VI "stripped for speed" that affects no front panel in any case.

  Is this just a problem of my state of mind?  It is true that in my life by far most of the code I wrote has been assembler for microphones integrated 8-bit, these applications are always tied to memory.  At this stage of my career balance reverse but many high-level code I write (Yes, I am a dinosaur).  So I tend to worry about the what will be my compiled code.  Should I just put another copy of the loop (in fact, it is only the nodes of property 'visible' 76 I need) on my schematic and disturbing stop on this subject?

  A number of observations.

  (1) the title of dinosaur not is still FRO seized with many of us competing (I used as well to play the game of 'ICan write this charceter to X lines...) »)

  (2) when you do a lot with the GUI, "David FP updated (this is a property of the FP to stop updates of the screen, serach for this) may spped things upward."

  (3) I use a GUI controller very often in my applications. I posted about it here.

  (4) if Chase you my tags I have a collection of GUI performance.

  I put the code in a VI called from my GUI controller (who calls your FG for the info).

  Regarding the memory

  When we used to depend on someone with a crochete crochet and beads to make our memory, it was justified. Today, memory is cheap and using you save time is fine. When you worry about memory, it's when you find that the code does not fit into 2 G more.

• What is the right way to use variables controlled by the two buttons and programming?

  First of all, I apologize if this has been discussed before.  I know not how to phrase succinctly the application, so maybe I just missed the search terms.

  We have several pieces of the Labview software in the laboratory that automatically control things like the taps and heaters.  Sometimes we also manually control these same things.  I'm moving old NI PCI (and older versions of Labview) maps to a variable and based on compactRIO system shared network.  However, I'm still not on best practices to achieve.  I need to be able to have a script running at any time control panel so that I can access, for example, a valve controller (which is just a Boolean), and I need power open and close the valve by programming other scripts.  I need, of course, the control panel to track the State of the valve until it opens another script, the Panel indicates that it is open, and the next push on the control panel it will close.

  Historically, this has been processed using structures business to move from a "computer control" and "hands-on" with global variables that define the State of the valves.  Of course, this is not recommended.

  So far, I've played with the help of two variables, a status of valve and the other for the State of button.  The Panel configuration then loops, reads the status of the valve and puts the State of button if the State of the valve has changed.  I can do this with registers at offset or with the structures of the event, but anyway, it gets very crowded and seems inefficient.  Is there a good way to do this in Labview?  It seems this is a common problem, so I hope there is an easy and elegant solution that I've missed.

  Variable published use shared network.  Your scenario and your manual of the interface and change the variable and then shared your cRIO reads fair value and writes the appropriate values.

  Now for a cool part.  On your manual interface, right-click on your heart control that you want to use to control the shared variable and go to properties.  There should be a data binding tab in the Properties dialog box.  You can bind a control/indicator to a published network shared variable.  So this button will always be attributed to the current state.

  Your script should just read the shared variable before resuming to verify that it is in the correct state.
