• Enter the following command without waiting for the current order to fill

  There is a switch to use that will enter a powercli command without waiting for the command to finish running. Can someone please tell me what the switch is?

  Hello, MNKrantz

  You can use the parameter - RunAsync for several of the PowerCLI cmdlets.  This will cause continuous execution to the next statement once the command is run.

  You can view the cmdlets are supported the RunAsync parameter using the parameter - ParameterName to Get-Command, which was introduced in v3 PowerShell.  So, for example, to search for these Core PSSnapin cmdlets:

• Upgrade CP 5.0 to 5.5 CP - or wait for the next version of Captivate?

  I use CP 5.0. I'm now interested in producing a release of HTML5 as well as in the use of a feature of speech synthesis improved (especially for German-speakers).

  If I understood a right to information, CP 5.5 would allow these two problems.

  Unfortunately buy an upgrade can become a stony path through the bureaucracy and would take about 3 months. So my question is: would you recommend to wait for the next version of Captivate? If Yes: how long should I wait wait that this version be available?

  This depends on the urgency of the requirement of your project.

  If I was in your position, and you will get a shot at this upgrade because of the bureaucracy of management involved, I would expect Cp6.

  He is soon, but I can't say when.

• get the structure of the event inside the while loop to wait for event occurs before the execution

  Hello

  I have a small problem, when I raise an event using a value change button, which works very well.  The problem is that the VI does not wait for me raise an event and instead runs the same event again, even if I have not pressed the button to start again.  The mechanical action of the button switch is released is.

  I was wondering how you get the structure of the event to wait for a user event, after that he executed the first time.

  There is no reason that the event should be raised twice as much that the only way that it fires in your code is by the user by clicking on 'Hall measure only'.

  Oh yes, there is, and I deserve a kudo for this one.  Mechanical action on the button is set on the switch until published, so click to generate an event, on the bottom and on the square, attached is an example.

  My boy has my students hate this question, and to be honest, I hated it.  When never would you do that intentionally?  Honestly?  Anyway to change the button back to normal (as default latch when released) and move the terminal button in the structure of the event where it is managed and it will work as usual.

• Live running without waiting for results

  Hello world

  I have a problem that I can't imagine would be unique and may have an obvious solution that I forget.  in any case, I have a class that contains an array of a separate allows class calling device.  in the class of device, there is a (vi) method to do a test of performance on the device.  What I need to do, it's stress all devices at the same time by running permanently the performance of tests on them at the same time, but not more than one on each device.  essentially I'd like dynamically create the threads running on each device performance test.  I have problems to find a solution in labview for this.  Someone at - it good ideas?

  If there was a way to tunnel the array in a for loop and just get the method will, but then that would mean each iteration start at a time that cannot be made.

  I have attached a picture of what it would look like if I had 4 go but I'd like to be able to dynamically generate each Exec.vi system running simultaneously.  I hope I described this problem pretty well!

  Thanks in advance

  Here's a screenshot of a VI I use to launch a case of a VI without blocking the main program (each call to execute CAN Loop.vi starts the CAN Loop.vi and returns).  In my case, each VI manages a station on a testbed of N-station and communicates with the rest of the program through the queues and events.  It is a little overkill for many applications, but it works well in mine, where the number of stations is determined at runtime, and each station can be controlled by another class (also defined at run time and configurable when the program is running!).

• Make a parallel loop to wait for an event?

  I'm working on building my first application designed master/slave, and I ran a little bit of a team of design and could use some advice.  Basically, I have my main loop, and then a couple of slave makes a loop to run a different treatment. It is very easy to control when one of the slaves starts with presence controls, but I find it difficult to make repeatedly turn and wait indefinitely for another entry to the loop master. I have attached a VI that should help the illsutrate.

• Capture video with Realplayer streaming has stopped working - will be fixed for the next version?

  When a video is streaming, Realplayer is supposed to create a small rectangular box in the upper right corner with a message 'Download this video '. In the latest version of Firefox that box no longer appears. So, the video cannot be downloaded. On the other hand, using Chrome things work as they are supposed to.

  Yes it is broken on firefox 22 for now you can watch similar apps

• go to the next iteration of loop for and continue execution of the previous iteration

  Hello everyone,

  I want to run a loop with an offset to each iteration. I explain: I want to run a task multiple times (for loop), but with a variable delay in each iteration.

  Thus, if we put t = 0 before you run the loop and I use 3 iterations. I put a writ of execution to the first ieration after 3 sec then skip to the next iteration of course without waiting the end of the previous iteration and run the current iteration after 1.5 s and go to the third ieration (once again without waiting for the latest iteration).

  I conclude: this is a simultaneous execution of a for loop (10 to 50) from different eras (variable time between t = 0 and each running of each task.

  The problem I found in the loop is the fact that I have to wait the end of the time delay in each iteration bfore going on to the next.

  Best regards

  In all languages, a loop iteration FOR happens AFTER previous.  However, go with the parallelized FOR loop can happen to you.

  No, you can switch to another catalog without waiting for the generation of thumbnails. The process will resume the next time that you open this catalog.

• Stop the multiple loop without delay to the cRIO

  Hi all

  the VI in cRIO has a large loop, it contains 4 small while in parallel to the work loop. In every little while, they have a stacked with a lot of frame sequence.
  I want to stop everything with only one STOP button on my host live. But when I press STOP, I have to wait for all the small loops completed their charge and finally the big one can stop. Is there any solution to immediately end all?

  Thank you very much

  1. you should not have the large loop.  Which is just to add unnecessary complexity.

  2. you hit the major problem with the Structures of stacked sequence: everything must go before it is complete.  The solution is to use a State Machine.

• force stop while loop

  Hello

  I'm writing a VI that make a transaction within a while loop. I replaced the operation with a simple mathematical operation in the attached photo of the VI. For loop in the picture, I just want to add 1 every 15 secs until it reaches 10 and stops. However, I also want to be able to force the while loop to stop immediately all 15 sec until the next iteration. Is there a way out of the waiting time for the while loop? Thanks for the help!

  Altenbach says:

  Use the event with a timeount 15000ms structure and an event for the stop button. Urgent stop immediately interrupts the time-out.

  Here's what I had in mind (LV 8.5).
