Re-initialize state of 'active' controls opening of vi

• Why active controls are grayed out?

  I have an array of Boolean controls that I've played with to see if I should turn the table or control.  Now, it seems that the table and control are active but gray (see fig. 1, Fig. 2: Fig. 1 shows the State of the table, Fig. 2 shows on the State of the control).  By clicking on each control in the table seems to "detoxify" them (Fig. 3), but which executes the code and then click on a control seem to turn all the gray (fig 4).  It is has no property nodes in my code that refer to "disabled" the matrix property or control.  There was, but I got rid of them, trying to understand why they are turning gray.  I mean, I'm turning grey, but that is to be expected.

  Any ideas?

  Thank you

  It just means that the table is currently empty.

• How do you dynamically change the enabled state of a control?

  I build a VI whose purpose is to generate a digital signal, post it on a chart and eventually save the data in a file. I have a trajectory control and a checkbox included in my front panel. When the box is checked , I want the State of the path control to be activated. If the check box is disabled , I want the State of the control path for disabled & clothing. Is there a way to get there or even just make it look like this?

  

  PS: I want also the checkbox for controlling whether or not the VI saves the data in a file, but I think I can understand the part.

  Right-click on the control, and then choose create the property node.

  Select enabled

• Can not see my active fonts open Type

  I used FontExplorer X Pro years as our font management tool.  In addition, we have had no problems to see in Active FCPX open Type fonts.  However, sometimes recently - an update for Final Cut Pro, or an OS to El Capitan, etc etc - update none of my fonts Open Type active in the system are listed in the tool of the police of titration, etc. in Final Cut Pro X.

  Has been taken in charge for these types of police removed?  Or is there a special way to access fonts open Type in Final Cut Pro X?

  I stopped using our FontExplorer X store a long time ago (it * was * free). However, you must make sure, you have the last update: http://www.fontexplorerx.com/?gclid=COrE5rHj68kCFQMMaQodBd0HLw

• Active control is indicated

  When running my application, the active control in the UI has a black outline that I find unattractive.  Is there a way to make disappear?

  Thank you.

  As much as I know there is no way to disable the highlighting in the active control. However, if the command has a lable, the highest point is around the lable instead of the control itself, it also means that if you move the lable off area of the visible screen (for example with a value of 5000 left label) the nail will not appear on the Panel.

• Active control of vibration of the flexible mono-faisceau

  Hi, im working on the active control of vibration of the unique flexible built-in beam, and I need to design that helps me control the beam active & passive.

  two experiences of control a robot with unique flexible bond. The link is operated in bending by two piezoelectric glued to the surface, and the local curvature is measured by piezoelectric sensors, forming a pair of sensors/actuators colocated. In both experiments, the articulation describes the same polynomial trajectory that excites the Eigen modes of vibration of the binding. In the first experiment anti-vibration with piezoelectric actuators are off, and we can observe a very long time to maneuver as link oscillations themselves naturally. In the second experiment anti-vibration are lit, and a significant reduction in the time settling is reached

  Cabo,

  So, it looks like part of what you are trying to do is the generation control system a PID in LabVIEW. Fortunately, LabVIEW includes a number of useful resources for the PID:

  Here is one of our books (with the tutorial files) whites, discussing implementations in LabVIEW PID: http://www.ni.com/white-paper/6440/en/

  Here is another tutorial on implementing PID using the PID.vi: http://www.ni.com/pdf/labview/us/implement-a-pid-control-system.pdf

  Here is the help documentation for PID.vi himself: http://zone.ni.com/reference/en-XX/help/371361L-01/lvpid/pid_vi/

  Finally, example finder LabVIEW has a large number of projects example PID you can experiment with. Just go to help > find examples, then find "PID" and select any project matches your planned the best implementation.

• no active controls on the front after sub vi opens

  Hello

  I have a little difficulty with my VI.

  I run a sub my main façade of VI VI.

  The sub VI opens, but when it is closed all of the controls on the front of my main VI is no longer active (buttons etc. not clickable).

  I put counters on the iteration of loop terminals so I can see that the program is still ongoing, some controls no longer work.

  Someone has encountered this before and offer all the solutions?

  Thnaks for the research, I appreciate it!

  See you soon,.

  Sorry sub VI is located in the loop of the selection of the files offline at the bottom of the block diagram.

  After playing with it for hours last night, I seem to have sorted by deselecting the option "front lock Panel" starting from the properties of structure of event!

• creation of structures: state machine with controls

  Hello, I wonder if someone can help me with something. I have a sequence, followed by the event structure / while loop.

  someone can help me. I want to create a STATE MACHINE.

  Here's a basic outline of the current structure, I. and this is what I want it to be. I wonder if its possible and how.

  I'm using labview 7.0.

  Thank you

  

  This is what I want?

  

  I looked at your Executive VI.  I don't have an easy way to save in LV 7 now so I'll try to describe in words how I would approach this mess.

  I think it can be done with two loops, a structure of the event, a case structure and not global or local variables.  In fact, there is probably some small business structures and lines inside some of the case, but nothing like as layers of ~ 12 nesting, you're struggling now.

  Look at the design model of producer/consumer (events) as a starting point.

  The loop of producer (event loop) will have the structure of the event.  It will be a case for each control that requires immediate action.  Those that I could identify: get telemetry, side, open Journal printing, abandon, press tank Mode (?) Temp tank (?), Scan, Stop, wait, Step (?) unique, continue and Execute. Most of the buttons must be set on the mechanical action of locking and placed terminals in the case of the event appropriate. So no local population is necessary to reset them.  Those with (?) have no event.  You can have a case of timeout to display Date and time, eliminating which (painful to my eyes) loop.  I don't know about the other stuff in the case of a timeout, but most likely, it is up to the other loop.  If the room 1, 2,... buttons change during trips, they may also need event.  Inside of each event is exactly one element: the Enqueue function.  Create an enum command and make it a typedef. Enqueue this enum value. The queue will be read in the loop of consumer where all the action happens.

  The consumer is your state machine. It has a Dequeue function to get a new order for the structure of the event.  It has several shift registers to transfer data from one case to the other.  These removes your global and local variables.  I'd shift for each of the following registers: the State (typedef enum), cluster of error, temperature (table), pressure (table), results (table), Stat results (table grapes) and a big cluster Indicators_Flags (typedef).  The cluster Indicators_Flags everything that is in the cluster you initialize in the black image sequence (and then never reuse) would have more all indicators except the berries in Maj separate records as well as all your globals and no status indicator, you might need.

  The structure of matter is the heart of the state machine.  All shift registers through it.  It will be the case for what the program does.  Everything in this black initialization setting in about 15 cases of Init.  The while loop to the right of the boot image goes away, but the case inside to become some of the cases of the state machine.  Chassis temperature cycling code goes into 1-3 cases. Mode code pump and read the pressure of your case of timeout event are 1-3 cases.  Code of telemetry: 2 cases.  Print the Page before: 1 case.  Excel code.  Abandonment of code.  Temperature and pressure cycling code of main program: 5-20 cases.  Graphics, record in file: more cases.  Break: 1-2 cases.

  I would like to make a list on paper anyway, you think that you may need and allows to create a typedef enum to control cases.  By making a typedef, it is easy to change without running all over the code looking for the constant in all cases of change.  Enum names will appear on the structure of matter as strings.  Create the loop, shift registers and the structure of the case.  Moving is part of both the original thread can duplicate the case until you have a case for each value in the enumeration of the State.  (Do not use the case of the mark for each value option because it will empty cases that you will then need to wire through.)

  Then copy code from various places in your existing code in the case in the new VI.  Try to avoid copying inhabitants that it will create new controls.  Name bundle to get data in and out of the big bend cluster registry and use ungroup by name.  This provides a free documentation of the data used.

  Check in a month when you have other problems. This will not be a quick fix.  But it will be useful to have a program that works and is easy to manage.

• Change the State of a control through DataProvider

  Hello.  I use a custom treeview checkbox.  The example I use works fine when the DataProvider is XML.  However, my DataProvider is an array of hash objects.  With this DataProvider, the tree is displayed correctly, but does not meet the ActionScript written to manage the interactivity of the boxes.  I go back down to this example from malfunctining:

  this.myTree2.dataProvider [8] .checked = 2;

  This line is Dim have drawn.  The treeview-checkbox custom has three active States.  0 = disabled, 1 = on, 2 = mode environment represented as a gray box.  Initially, all the elements are checked = 0.  When I run the above line, the content of DataProvider changes indeed (according to the debugger), but the control itself does not update visually.  Back to this line a second time, DataProvider is always in the checked state 2 =.

  I'm new to Flex programming, but I am an experienced .NET web application programmer.  Is there something I need to do, like 'cool' control when the DataProvider content changes?

  I use Flex Builder 3 on WinXP, trials primarily with IE7.  Thanks for any idea that all have them.

  You will need to call itemUpdated on the collection.

• OfficeJet k7100: 'lines of control open or shorted' repeated error - 344 cartridges

  I have an officejet k7100.

  I'm getting a problem repeated with original hp 344 colour cartridges

  the red light on the left flashes (which indicates a color cartridge problem) and the printer refuses to print.

  When I do a test by TAPPING, the error is "the pen in the left chute has 1 or more lines open or shorted control."

  I tried - to buy 2 more cartridges.

  the purchase of a second identical printer (used) on ebay.

  same error each time, even refused to print. What combination of printer cartridge / I'm trying. very frustrated...!

  ideas (apart from 'buy epson') most welcome!

  There are a few things to try:

  • Remove the color cartridge and try to print a page.  (The printer may still indicate a missing cartridge, but it should display ink backup mode).  The printer now shows that the black cartridge is at fault?  If so replace the color cartridge and remove the black cartridge.  If this prints correctly the black cartridge was involved.
  • Clean the cartridge and the contacts in the printer as shown in the document here.  It is a different printer but same principle.

  If the above does not help, I would say by the way by the troubleshooting steps described in the paper here.

• I installed 4.5 and now when I download a book, I get a message saying error, activation control?

  I used Adobe Digital for a long time.  Today I installed the version 4.5 and I now get an error message when I download a book, telling me to check the activation...

  Hi Newestguy,

  You must manually remove the activation file and then resign in. Please follow these steps:

  You must have administration.

  On Windows it can be found here:
  Open the Windows registry using the command prompt and type "regedit" or by opening the start menu and by searching for "regedit."

  Look for the following folder:
  HKEY_CURRENT_USER\Software\Adobe\Adept\Activation

  The "Activation" folder can be removed completely.

  On Mac it can be found here:
  In the Finder, locate the 'Go' option in the menu bar and click on "Go to folder" and type the following command in:

  ~/Library/application support/Adobe/Digital Editions.

  Delete the activation.dat file in the "Digital Editions" folder.

  ADE to restart and it should be disabled at this stage. You should be good to reconnect.

• "View Composer agent initialization state random error.

  We use 4.0.1 build-233023 with linked clones with persistent desktop computers and we get "View Composer agent State (6) initialization error: unknown failure (expected 0 seconds)" errors that occur randomly after commissioning.  I've read several articles that indicate to restart the virtual machine will fix that, while it's very embarrassing that it works.

  However, we receive this error on the VMS, after commissioning and users have already connected to the virtual computer.  So if the VM goes to an error state, users get an error indicating that the office is not available!  A restart/reset of the user's virtual machine will correct this, but it would not be feasible.

  A - someone to find a permanent solution to this?

  Thank you very much!

  Food for thought: I removed all the variables unnecessary excesses on the 'Run' button and changed my script to restart to wait 30 seconds to run.  This time, the refresh of the Office were 0 errors (usually I see 1 or 2 with the initial thrust).  Once is not a trend, but I wanted to throw it out there.  The other thing, we've changed is diminished the simultaneous provision to the vCenter server to '1' (just in case this error is caused View Composer have too busy).  I will update if things do not work in the long term with the fixes above.  Thank you!

• Order of initialization of the beans controlled in ADF

  Hi, I have two session scope controlled beans A and B and I want to A contractor to instantiate a local reference to B.
  
  B b = null;
  A() {}
  b = (B) JSFUtils.getManagedBeanValue ('B');
  }
  
  Finally, the getManagedBeanValue method uses a createValueExpression with the B bean binding.
  Are we sure that ADF has initialize B session bean and create the binding at the point where we call it a manufacturer?

  Hello

  If you use a ValueExpression for access B then Yes, the bean is instantiated by JavaServer Faces. However, there is another option, which is to use a managed property in a configuration. bean managed at the bean managed A you would create a property as

  private B b = null;

  public void setB (B b) {}
  This.b = b;
  }

  public B getB() {}
  Return this.b;
  }

  You configure then a property managed with the name 'b' and the reference to # in the a configuration. In this way, that you don't need to use a ValueExpression in bean managed code
