• Flatten to a string to send arbitrary objects by messages from the user interface?

  Hi people,

  I am trying to send arbitrary data by messages from the user interface defined by the user to my labview interface. Something funny happens then: if I send the data through the message of ui, it seems I have something strange. There is only one character or nothing in the message of the user interface that reached my reminder.

  It seems that flatten channel also creates control characters that are interpreted by NI TestStand and Labview not as members of the chain, and for this reason I only get incomplete data. within the action of testand, which creates the flattened data, I put a dialog box to display the string data, and it seems that at least up to 255 (ascii) characters are used.

  Is there something like uuencode/uudecode to avoid this problem?

  Thanks in advance

  His «binary"produced by «Flatten the string» string Apparently I thought, the LabVIEW data type is incompatible with the API of TestStand from LabVIEW. In conclusion I would classify this as a bug (sorry people, at least there should be documentation) API for LabVIEW TestStand 2014.

  As a solution, I use flatten it in XML, which is a printable and human readable 'normal' string.

  It was trial and error, and I'm not enjoying this.

• WIN8 registers touch but no reaction from the user interface?

  Anyone having problems with Win8 button when your fingers are clearly registered (Windows gives this feedback from the spherical ripple effect) but the user interface under your finger does nothing? No not the button and so on.

  I live it with some Chrome for example, with the small button tab when it is near the top edge of the screen.

  If I drag the window to the center of the screen, I have no problem with getting keys recorded. Hit the button new little tab gives no trouble.

  When user interface elements are close to the edge, no reaction, even if the wave indicator appears.

  Cannot know if it is a driver or a HW problem. I use X220T.

  Example screenshot

  May be a problem with Chrome, in fact. Tried with Firefox and the new tab button is a lot easier to hit. ---> will give Chrome devs a hint

  EDIT: what you know! The new beta version has already dealt with this issue:

• 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).

• Scripts from the user interface.

  I am trying to create a script that generates a window and fills with icons pre-made depending on how

  documents are opened in Photoshop. then, depending on which icon is clicked, it stacks the files in a certain way.

  My question is, if I fill the window with the image buttons, which are placed there by a switch, should I put the onClick within the

  spend according to each case?  or do I have to put it out after the window shows?

  If you create image buttons, you must put the onClick where you create them--inside the switch, otherwise you will onClick functions that don't relate to anything and will throw an error - if I understand what you are doing.

• Lost the user interface in Premiere Pro?

  A few weeks ago I signed up for creative cloud. I started using the first Pro CC. I knew that I couldn't take advantage of the Mercury engine because I have ATI Radeon HD 4870 512 MB. I was still able to edit and work. Today I went to send timeline to grade speed and it took forever to export, finally to halfway to send it, I gave up and revived Premiere Pro. When the first opened my UI had disappeared. Drop-down menus have all their but disappeared from the user interface. If I went in create new title, I could see that window, but the chronology, garbage, source and windows Records were not visible. I know that the sequence is always there because if I hit the space bar the sequence plays through my Kona card. I closed the first and I got a pop up menu Nvidia Cuda ask my update of drivers. It's strange because I have a card ATI not a Nvidia card. If I open all the other apps After Effects or Photoshop, all of the user interface is here. What gives?

  Ann Merci for the info, Ann. However I realized that it was just that the interface was dragged all the way upward under the white bar that says first projects.

  When I saw the arrow pointing down I realized that I had to just drag the interface down. Simple mistake. Thanks again.

• To access the check boxes in the user interface programmatically

  Hi all
  I have the following usecase.
  1. I have a table that has 3 columns, first two columns are read only output of the label component and the third column is a checkbox.
  2. I have three lines in the table.
  
  Now:
  1. when a user selects the check box and click on a "submit" button I want to check that it should have selected at least one checkbox.
  2. for which I tried to access the table from the user interface programmatically, but it does not work.
  Is there a way I can access the values?
  
  Thanks in advance,

  Hello

  The box must be bound to an attribute line in the table is related to data collection. If yes then simply loop through the lines and check if the attribute has been set. For example, if each line has a "checked" property, so you can ensure at least a line "checked = true' in your action. To access the collection, you can use something like:

  Object initialRowKey = table.getRowKey();
  try
  {
      int count = table.getRowCount();
      for (int i = 0; i < count; i++)
      {
          table.setRowIndex(i);
          MyObject row = (MyObject)table.getRowData();
          if (row.isChecked())
          {
              // do something, set a flag to true, etc.
          }
      }
  }
  finally
  {
      table.setRowKey(initialRowKey);
  }
  

  The code above assume that you linked the table to your managed bean using the "required" attribute in the table.

  Kind regards

• How to upgrade to the user interface of a screen that is extracted from the stack?

  Hello

  I am currently having a problem in the UI update.

  I have two screens called 'OverviewScreen' & 'DetailScreen' and in the upper part of the two screens, I have three buttons

  (i) back

  (II) next

  (III) charging

  In the entry of the app normally I posted the 'OverviewScreen' and in this screen, back, next buttons are inactive positions (just to have two sets of images, one active and one for idle) and if the user clicks on an item that is displayed in the cell, then I'll navigate the user to the "DetailScreen".

  Now the stack should have two screens,

  at the bottom - "OverviewScreen".

  at the top - "DetailScreen".

  and in the "DetailScreen" - I showed the image is active for the "back" button (because the screen is lower in the stack) and for the next inactive button image.

  Now if the user clicks the back button I navigates to the "OverviewScreen" which is called the UiApplication.getUiApplication (.getActiveScreen) (m:System.NET.Sockets.Socket.close ()); in the case of touch

  Now the "OverviewScreen" located in the bottom of the stack to the front UI (basically when I built it for the first time, it contains inactive images next and back) - what I want here is I need to show the following active image therefore needs to update the user interface of the screen that displays battery

  Because,

  OverviewScreen (back, next inactive images)--> DetailScreen (back - active, next - inactive)--> new OverviewScreen (should show the back - off, next - active)

  For this, I tried with what follows, but none works,

  If (event.getEvent () == TouchEvent.CLICK) {}
  UiApplication.getUiApplication () .getActiveScreen () .getScreenBelow () .updateDisplay ();
  UiApplication.getUiApplication () .getActiveScreen () m:System.NET.Sockets.Socket.close ();
  Returns true;
  }

  I even tried with invalidate() and dopaint() but none works

  However, I realized the functionality if I press the off button in the "OverviewScreen" he navigated me to the "DetailScreen", juice wants to show the icon active next button?

  What should I do to repaint or update the user interface of the screen here?

  Thanks in advance,

  Kitty.

  Found a solution

  Override the method which is found in the net.rim.device.api.ui.container.MainScreen and in this method, I have changed the image for the button and this method is called in the current active screen using getActiveScreen () .getScreenBelow)

• 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

• How to get an array of integers to user in the User Interface

  Hi all. I'm not a very experienced user of the CVI. I have almost exclusively coding in LabVIEW but have a client who wants all of their work in the CVI.

  I've been very fruitful so far (set up a Modbus API from scratch that supports all types of connection) but am confused on how I can get the integer multiples of the user without limiting the number of integers I can get. Essentially, I need to be able to get an array of integers to the user.

  General information, I am building a user interface to test my Modbus API. There are Modbus functions to 'Write multiple registers' and 'write multiple coils. I want the user to be able to enter all the values they want to write in one command.

  What is the best way to get an array of integers through the user interface?

  The easiest way is probably to allow user input in a textbox control numbers: items can be separated by spaces, commas, or even a line break (using ctrl + Enter). You will then need to extract the string from the TextBox and analyzed for numeric values using any non-digit character as a separator: strspn (string, '0123456789'); can be used for this.

  More complex, another possibility is to use a table control to receive user input: you Dresses an empty table with a reasonable number of roews, or you need some codes to add new lines as long as the user fills all those already existing. On the other hand, it will be easier since data recovery in a simple statement, you will all return values: GetTableCellRangeVals (panelHandle, PANEL_TABLE, VAL_TABLE_COLUMN_RANGE (1), table, VAL_COLUMN_MAJOR);

• 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

  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.

• 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...

  David Koch

  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.

  

• The best way to separate the user interface in the model LV 2012 queued Message Handler?

  If you create a new "queued Message Handler" new model 2012 LV, you will see a blue box in the case of "Update view" that says the following:

  Code Recommended - If you wish to decouple the Message Handling Loop from your user interface, consider creating User Events (like the "Stop" event in this VI) to message the Event Handling Loop whenever the user interface needs updating.
  

  I would like to give a suggestion, but I am struggling to find the best way to do this and still keep code modular.  The template creates a user - Stop.lvlib "event with a create/Destroy/fire Subvi.  I would like to create a library of "User event - Update UI.lvlib" similar with similar Create/Destroy/fire Subvi keep this new modular and separate user event.  The problem, I am struck, is that there may be only two hydrants in case Structure dynamic event so, how I modularlize creating user events in separate SubVIs and always maintain this dynamic event terminals?

  As a follow-up on the issue, it would be preferable to have a library of user by indicator events that must be updated or that a single UI update of the user and then event pass a cluster as the message that contains the name of the control for the update (to use with a structure of matter), then the data to go with it?

  Thank you!

  Instead of having the events to record in the 'create' methods, you could be part outside your 'create' SubVIs and then simply bundle them. Then, you create your individual event of the user management. See excerpt where I created a vi 'Create user event - Update' in front of the stop.

  

• Structure of the case duplicates all the indicators on the user interface.

  I create a true/false case structure that contains several indicators for each of the cases respectively.  These indicators are displayed simultaneously on the user interface.  Is there a way to have indicators or indicators to replace the other as the other case is active or control must be in the user interface at the same time?

  Thank you!

  Is there a reason you want to duplicate the indicators?  The normal practice is to move the indicators outside the structure of the case and the wire coming from each case out through a tunnel.
