• Impressive transformation slow due to the updating of the user interface

  Hello

  I feel a huge slow down in my test as engine

  I update the display after each test. It consists of a rather

  "simple table" with a subtle change of color and bold

  to indicate the failure or success of the test:

  

  I have also tried several things to determine what routine was

  make the program almost crawling like a snail, here's my

  results:

  No UI refresh: 0m48s (same as Teststand with no updates of the user interface)

  The discount but no page table switch: 1m06s

  Bay of refreshment and switch page: 1m26s

  There are 314 tests, up to 314 redraw and possibly

  switch page 314 to reposition the view. Which gives the

  following user interface refresh costs:

  

  Update of the table: 18 years/314 = 57ms (replacing just a single line, Center to top)

  Switch to page: 20 s/314 = 64ms (bottom right corner)

  Is this really the case? Is there a way to make the refresh of the user interface

  faster? Create two separate loops/threads, one to make

  the test, one for updating the UI asynchronously?

  I understood for an overall picture about different

  widgets, but here I'm 'just' display of channels...

  Well, multi-listbox control is a problem if your change causes access to the muliple property node. For each property node LabVIEW normally does a refresh of the user interface which is very quickly. Fortunately, there is a fairly easy way to fix this.

  Use a node of property for the current VI (just drop a property node and change its class type VI Server-> VI reference) to get the reference of the Panel. Then use another property node connected to your reference of the Panel and select update from the Panel to postpone. Set this value to true before your Listbox (and any other updated user interface) and set the value to false then.

  

• Slow response from the user interface with acquisition of data of type long time

  Hi all

  I have a question to ask more out of curiosity than necessity right now. I've built a program that acquires data from the accelerometer and the Treaty in a number of ways: filtering, FFT, FRFS, things like that, but the answer of the UI is still slow, because I need a resolution of frequency of 0.2 Hz for my data domain, which means that the sample acquisition time is 5s and all this awaits before execution.

  My question is this: is there a way to completely isolate the user interface of data acquisition so that it responds immediately?

  I tried a design model of producer consumer with queues, but found everything to be always waiting for samples to be taken. Maybe it was exactly as I did.

  Thank you

  Phil

  If you need to sample for 5 seconds in order to have enough data to analyze, so unless you can "predict the future" and "knowing" the five seconds of data, simply wait for the data that arrives.  Using parallel loops of producer-consumer will allow data acquisition to proceed (for the next 5 seconds of data) while you do the analysis, but you still have to wait for the data to be analyzed.

  Note that the previous paragraph assumes you are collecting data in 5 seconds 'chunks' and analyze each "chunk" (independent) on arrival.  You could also do something like having a "second 5 sliding window" which moves, say, a second at a time, giving your FFT a finer resolution of 'time' (at the expense of their independence).  This would be a (slight) change in your loop of producer (you want to taste in 1 second pieces, accumulate 5 these pieces) and the consumption loop (start analyzing, spewing a FFT every second, while replacing the older "chunk" with the most recent - a queue with loss can do for you).

• Asynchronous call still slow down the main VI

  Hello!

  I currently have a 'main VI' quick process underway, and I have a Subvi, which is essentially a device data collection. However, this Subvi works at 1 Hz, while my main VI runs a lot faster.

  I created an asynchronous call to the Subvi and set it such that the hand is not expected to incoming data. I followed these very simple instructions: http://zone.ni.com/reference/en-XX/help/371361L-01/lvhowto/acbr_call_and_forget/

  However, when I run the present, my main VI is as slow as if I did not use an asynchronous call. For your information, the only node inside my main while loop is the node "Start Asynchronous Call.

  Is there something I'm missing about how works this Subvi without slowing down my main VI?

  Thank you very much!

  I guess that your main problem is that the DLL calls are set to run in the user interface thread.  This could prevent your main VI to update until the end of this call to the DLL.  Try to set their 'Run in any thread.

  In addition, there is no need keep saying this VI to run over and over again.  He needs is called only once.

• Offset of the user interface after update of El Capitan

  Hello. Since I upgraded my Macbook Pro late 2013 to El Capitan retina, I've known GAL of the user in function, mainly opening animation of safari and switching between desktop computers. These issues are only to make my user base, I created a test user and concluded that the test user was not the offset of the user interface. I have reinstalled the operating system, as well as talked to apple. Apple had me reset the Pram so that delete files, including:

  / Library/LaunchAgents

  ~/Library/LibraryAgents

  / Library/LaunchDaemons

  / Library/Caches

  ~/Library/caches

  and many other files like these.

  None of that helped, my UI lag is still there and fine. Also, I'm not sure if this is relevant; However, my recovery HD (available from start by pressing the alt/option key) is not an option. I'm not sure if the files I deleted with apple support caused it or reinstalling the operating system has done this. IM thinking delete files because I reinstalled the operating system using the HD recovery.

  Does anyone know how to fix the lag in the UI? I know other people have this problem, google search and this forum but no clear answer has not developed.

  Thank you

• Error variables look a tab after race change the user interface

  Hello

  I have a problem which seems to be a bit like this:

  http://forums.NI.com/T5/NI-TestStand/error-viewing-variables-tab-in-runtime-operator-interface/m-p/1...

  The VI I'm running is a step of edit of a type of step. LabVIEW checks if the property 'Step.Setup.ReadMeasName' exists, fills a listbox with her if she does. An another ListBox with all available measure names will also appear on the user interface. The user has an Add and Remove button to remove the 'ReadMeas' list box measures or add them to it of the listbox 'MeasNames '. Several names may be added/removed according to what is selected when you press the buttons. Once 'Fact' is clicked the VI writes the 'Ref' to the list box "ReadMeas" property to "Step.Setup.ReadMeasName", using a node to set the value of property that is passed the TestStand sequence context. If the property does not exist it creates.

  The only time where I have any problem is when I try to remove items from the property, after it is already initialized (i.e. non-empty). In other words, if I run the VI of teststand, put several names as in "ReadMeas" click on done, again run the VI (already added names appear in the box when the user interface is displayed, LabVIEW reads "Step.Setup.ReadMeasName"), then remove the names. IF "ThisContext.Step.Setup.ReadMeasNames" has opened in the tab 'Variables' step when you try to remove the names, I got this message in the Variables tab: 'one or more errors occurred. Please save your work and restart the application. "If I'm careful of not having expaded 'ThisContext' in the variables tab, but check the property before and after the removal of names in the list it does not work properly, and there is no error.

  This isn't a big problem because I doubt that the end user will check to see that the property has actually filled, but I still want to fix the bug if possible. I installed the patch for TestStand 2010 and the .net Framework 4.0. Someone has an idea of what might be happening here?

  Thank you

  Josh-

  Looks like you are running in a known issue 193751, which is documented in TestStand 2010 and 2010 SP1 known issues list. It is a problem that we intend to fix in a future version of TestStand.

  I hope this helps and I'm sorry for any inconvenience this issue may cause you.

• Generation of the user interface of function error

  Hello

  just one tiny problem: on a Panel, I have a progress bar. Now, if I go to the user interface to use in the user interface editor, the UI must be saved, compiled and linked and results in some errors, see below. Not a real question that I can test all events/ToolTips in the user interface editor, but mistakes are always a little unnerving .

  

  Hi Wolfgang,.

  This is a bug confirmed in 2013: #424745.

  It is expected that the code for the custom control must be compiled and linked (unregistered, however). However, the link must succeed, and you should be able to interact with the custom controls everything in operation. This was the behavior in 2012. Certainly, it is not a good way to interact with a progress bar in the user interface editor. But for other custom controls (control password, for example) it makes more sense.

  Unless you are logging in to each account and switching between them - have each user run a lot of things.  Now * that * could slow down the computer.

  Otherwise, it's just - unused accounts unless you connect to them.  Again, storage space and unil you get below a few GB of free it - not no more worries.

• Feedback from the user interface

  In the Simulator (090), when the user selects the gear (top right) to display a list of parameters to select, the bar of the background and button scrolls down.  However, it is not intuitive how to return to the "main" screen  Still, the down arrow in the main screen button bar pointing downwards and is grayed out.  There seems to be a second "up" button placed in the Center, but it is masked by the "Media" button  Suggest that it is more obvious to select and restore.  Suggest you hide the button bar, make the less gray background and make the arrow more obvious upward so that the user knows that they can select the area to restore.

  Don't forget, this is still in phase beta/Simulator, I am sure that the final design of the user interface will be better/more intuitive.

• How to intercept the sockettimeout exception message and display in the user interface of the view?

  Hi my jdev - 11.1.1.7 version

  I ask a socket connection in my AM and I want to catch the exception of the sockettimeout of t and display the error message in the user interface of the view layer.

  I use customException class that extends DCErrorHandlerImpl, but if we use try catch, then exceptions doesnot reach customclass.

  How to catch exceptions and return to view the layer if we use the operation binding. ?

  Because you call the operation via the link layer, which is perfectly fine, you do not get an exception at all. Exceptions thrown in methods called via the link layer are captured by the framework and transferred to the appellant in the operation binding.

  For that, you get the list of errors after the call returns and add them as messages of faces

  execute the method

  Method.Execute ();

  List errors = method.getErrors ();

  If (! errors.isEmpty ()) {}

  handle errors errors here is a list of exceptions!

  We only get the first

  E receive = errors.get (0);

  FacesMessage msg = new FacesMessage (FacesMessage.SEVERITY_ERROR, e.getMessage (), "");

  FacesContext.getCurrentInstance () .addMessage (null, msg);

  }

  no error return to normal work

• Lumetri slows down the encoding of color correction more "obsolete."

  Based on my own informal tests, I notice that Lumetri effects on an element in a sequence slows down the process of encoding significantly compared to the same general objective realized with effects of correction of the so-called color "obsolete". Other messages on the forum seem to confirm this.

  I guess the older "out-of-date" color correction effects are far from obsolete. Looks more Adobe innovates and push this crowd of material premium to their last, Lumetri, but that the older effects are more obsolete than obsolete, probably to be there for a long time... iow, use them as you wish for you will hit all compat issues in the foreseeable future.

  Is that what that sounds right?

  My goal by asking is to better align myself as a user of first... my tendency is to take the final product as user recommendations, but that can be a trap when it is really a big innovative push who sometimes material/performance hits that make it unrealistic for all users.

  I have a portable old 5 year, the Sony Vaio VPCF215FX w/6 GB RAM, NVIDIA GeForce GT 540 M, 1 TB SSD.  I am able to do, but I really need to think intelligently avoiding external USB drives, using smart rendering, etc. When I tried an experiment with older color effects, I saw a significant reduction in the encoding time (General of my test described below). For this reason, I'm stepping back and thinking that the push 'use Lumetri' everything is beautiful for those who really need, want, and also have the material that can reasonably be taken in charge, but maybe not for someone like me, at least if I can avoid using older effects and with all the same. I just can't justify Lumetri in some cases where it slows down encoding medium.

  It is not that my hw is unable to use it but when I can use older effects and get a nice discount time coding for my not pro use, seems useful to avoid the Lumetri currently, until the upgrade hw or something. I wanted to just check-in here on the forum because everything above is me in a vacuum, I felt ready to hear some voices from the community on my point of view.

  Oh, my test...

  Create two sequences, each with the same single element from the same ~ 60 second clip of Canon EOS 70 d (ALL-I, 1920 x 1080, 23.976 FPS, MPEG-4 AVC / H.264, VBR in.) Container MOV), where each sequence has the following effects of color...

  Seq1-UsingLumetri uses the following color effects:

  • Lumetri #1 (primary): globally adjust contrast/tone/WB Correction of basic and secondary HSL to affect parts of the installation image.
  • Lumetri #2 (secondary): none other than the Secondary to affect an object moving on tracks with a circular mask.

  Seq2-NonLumetri uses the following color effects:

  • The fast color corrector: adjust overall contrast/tone/WB (identical to what Lumetri No. 1 above is without its Secondary).
  • #1 RGB color corrector: Color Correction secondary only to affect certain parts of the image (the highest Lumetri #1 only secondary HSL what).
  • #2 RGB color corrector: secondary color Correction only affect an object moving on tracks with a circular mask (what does the #2 above Lumetri).

  I coded then everyone if above with such parameters as input media, none made smart (because I want to see encoding time with effects) and out of type, etc. The result was that Seq1-Lumetri took about 225 seconds, while Seq2-NonLumetri took about 150 seconds, about 50% more time when using Lumetri on the same ~ 60 second clip entry.

  Note, part of the reason why I'm here is to ask my question above one, sort of general/summary, but it is also based on my not not having seen a single Lumetri color correction tutorial that describes these nuances... check in shades that seem to be essential for efficient use of the product by someone like me. I want to know about Lumetri, that's fine, but I also really want to know how to use the product together more effectively... to do this, seems to me, should not take account of the effects of color more older 'obsolete '. I want to at least know if there is agreement, or if I could be missing something here.

  Thank you!

  "Legacy" color tools more elderly are simpler "peripheral" in the code if I understand and don't work... especially... but as has been clearly established by colorists, especially if you do anything with the "" range"in the young or 3-way controls, you can get weird and very... results not correct not...

  That said, if you stick to their tools without using the modifiers of the range and not to push things too far, they work for the most part, kind of like what you would expect.

  Thus, on this laptop old of yours, stick to the Legacy tools is probably a good thing. And works very well for you. If you move up to a more recent material, you probably want to look more like the Lumetri Panel.

  Currently, I am working with the help of a mixture of Lumetri for the 'main' ranking, but using 3-way & RGB secondary additional & such.

• Model of spectator in the user interface

  Hello

  Is there a way that I could extract screenshots from the Model Viewer that you want to include in my UI dynamically?

  Thank you

  I have seen this command while searching for answers, but I, I'm not sure that it is a reliable operation.

  Fix. This is an undocumented feature, so not supported by Adobe. This means that it could easily disappear from ExtendScript, or change with a future update without warning. I use it a lot for my own non-public scripts and it works very well as long as you're only dealing with 8 and 16-bit projects. 32 bit breaks the appearance of the image and is unusable. Dan is correct while saving the image in this way might be a backdoor to do what you are wanting. You could also look at a cap screen command line option, but that would of course include each of the user interface and if the user had several monitors, several images to sort, so probably not a good idea.

• How can I change the size/scale of menus of the user interface in CS6?

  Recently got a new laptop to work running windows 7, CS6 and menus of the user interface are almost unreadable. Help, please!

  I can't tell you how many times I hear it, and it's something that has to work on Adobe. The problem that you are running is that, as our instructors to expand and the resolution increases, all the elements in our software applications (buttons, menus, etc.), are getting smaller. Your only current option is to reduce the screen resolution of your computer. To do this, right-click on your desktop, and then choose the resolution of the screen. Slide the resolution down until everything is readable for you. Usually, something in the neighborhood of 1280 X 800 works but it is very subjective for each user.
