Disable the button by using the node property

• disable the node property problem

  Hi all!

  I want to do a VI that the user will not fool around with the button.

  So I put in my case for the "change the value" event, a node property disable during 1 second (disable) and out of it, an enable.

  The problem is that if I press the as button 3 times in 1 second, the button will still change the value 3 times, as he has memory.

  I want to just the user to be able to make changes to the value only after 1 second and not save them. I hope I made myself understood

  Are there any suggestions?

  You may use a state machine with two loops. UI loop place the actionwith a timestamp and the loop of consumer can compare timestamps to decide if enough time has passed, or if the action should be discarded.

• Use the node property to get the value of control

  Hi all

  I know that you should keep the use of local variables to a minimum in order to avoid race conditions. Is this the same problem if you using the eg property node. a digital control?

  The reason why I want to do is to keep the son of the intersection when I need to use a control on one side of the diagram across the diagram...

  Basically to make the scheme simple and enjoyable to watch.

  I hope that makes sense!

  Good day!

  Kind regards

  Exactly. Perhaps, he creates the race conditions and should not be used. Using wires to connect the terminals is the approach only "Save".

  In addition, performance decreases in the following order:

  -Terminal (+)

  -variable (0)

  -property to value node set (-)

• all the nodes property objects and objects grouped

  Hello

  Now position an on my GUI objects in the center of the screen using nodes property. However, I don't want to have to have a node property for each decoration, image and control. Is it possible that I can group all the objects and then use a property node to position them? I tried to use the property node all objects, but none of the clues seem to apply to my group of objects.

  Help please!

  Thank you very much.

  John

  p.s. I downloaded my vi test. The graph, the decoration and the exit button have been grouped. control over check.vi to set the object to be moved.

  Tabbed pages are a great way to group objects GUI.

  Rather than use a decoration,

  • use a tab control
  • Delete everything except the first tab
  • Hide tab
  • The value of the proprties of the tab control and control on this page is move, hide, display as well as the tab control.

  I hope this helps,

• Writing to the nodes property DAQmx channel does not refresh the channel values

  Hi all

  I have a riddle.  I created a task programmatically in LabVIEW and programmatically added several analog input channels to the task.  It's easy.

  I wish that my user must be able to modify the individual channels within the task.  To this end, I created a set of screws that allow it to change the settings appropriate to the channel (for example, if it is a channel of thermocouple, it can change the type of thermocouple, CRC value, etc... If it is a strain gauge channel, it can change the coefficient of fish and so on).  These screws all works beautifully, like the VI where they live.

  The specific question that I have is that writing to the channel property nodes refreshes not communication channels.  See the images below.  The first image is the code that needs to define new channels of communication:

  

  Note that immediately after setting the property nodes, I read their values back, just to see what comes out back.

  The second image is an image of the public Service immediately after the execution of this VI.  Note that the values read from the channel property nodes did not updated to match to the set of values, but instead kept their initial configuration values:

  

  What I am doing wrong?  I fought this for a few days now and I'm stumped.

  Thanks for your time!

  Hi, Diane.  A week ago, I also had a problem changing the channel properties (not sure that our situtions are exactly comparable, but...).  My 'solution' to want to change the appearance of the task was to just throw the original task and recreate all the elements of the task from scratch.

  I've not done enough 'experiments' to work when you can and cannot change, but am now much more cautious...

• From numerous references to sub - VI you use clusters returns an incorrect reference to the nodes property

  Hello

  I'm moving in the data from the controls on the main gui (also information using indicators) in my Subvi. For the life of me I can't figure out what the problem, I tried dang near everything so any help is very appreciated. Also, I suspect that my cluster may contain too much information. Finally, yes I know there are a lot of posts about it, but none seem to alieviate my problem.

  (Just a warning, if you try and you run the code, you will first need to change where the data file is stored, it only takes all the sensors and calculations information and stores it in a file)

  I couldn't reach all the Subvi, so I joined him relavent those. The main problem is the LangmuirTroughStepperMotorCodePlusSubVi in DataGatheringSubVi

  # You can not use 'create a control '.  I have no idea which wire or terminal you think that using on.

  You must:

  Remove one of the constant pink cluster.

  Move the static checking references and functions of Bundle for out of the loop.

  In each group, take the wire coming from the output of the beam, he wire through the wall of the loop like a tunnel.  Connect it to the appropriate entry of the Subvi.

• Connecting the node property programmatically to objects in front?

  When I right click on a property node, I see the option to connect to any object of front panel.

  Is it possible by programming? I create three charts XY and I want to know if I can control

  the color of terrain for all three charts XY with creating ONLY a property node (color graphics) and placing it inside a loop for

  and for each iteration of the loop for example, linking the property node to different XY graphs.

  See the image.

  Hello

  what you can do is to select the option 'disconnect control' when right clicking on the property node (it becomes a generic property node to pass a command reference XYGraph), place this property node in a loop for, before the loop, build an array containing references to your 3 XYGaphs (right click on each XYGraph > create > reference).

  Hope this helps

• cannot disable the nod on occasion? 10.1.1

  In iMovie 10.1.1 I can't disable snap to mark? I checked the other questions and it doesn't seem to work.

  Have you tried to disable alignment in the view menu?  Make sure it is not checked.  This applies to all the slam.  I don't think you can disable just for the brands.

• Control disappear the node property for the post of Pentecost

  Why what happened? I accidentally create a situation like that in the VI and control disappear without any errors, can solve this problem, but the control never return to its original position.

  Hi Rodrigo,

  you are unable to find the control you went it off to the left...

  LabVIEW has some problems when the FP elements are moved by far (in a sense). These problems include not being able to find/move this element or results in an object with a width of 0.

  Why someone would move an item to > 16000 positions in both directions?

• IM new to LabVIEW. Is it possible to send the signal to more than one parcel on a chart by using the value property of the graph node

  I'm new to LabVIEW. IAM trying to display two plots on a graph using the node property value charts. I tried to feed the two signals into a signal of fusion and then in the value property node, but it did not work. Then I tried to build a table of two signals and it powers the value of hardware node. It did not work. What escapes me, should I use the node property value this way?

  
  

• Disable the Drive on Yosemite property or repair permissions

  I have some files on my Mac telling me now that I don't have permission even if when I go in the menu "Get Info" I'm listed as "Read & write."  I then tried to fix the permissions, but there is only one button of first aid, no tab with a prompt to repair permissions in disk utility menu.  So since I was the only person who uses the Mac, I tried to disable the Drive property.  I went to the disk utility, but there is no option to do either.

  Are these system files or your own files. In addition, you can not do an ERD on a mounted volume, you must boot from recovery to do.

  OS X: on OS X Recovery - Apple Support

  But if these files belong to you, then a repair permissions will not touch them.

• Problem with the Value property node (MacOS)

  Insofar that I tested it, the nodes of property Value (and value (signalling)) do not work under MacOS: value property is a Boolean value, the value (signaling) as a cluster (width, height).

  Even with the Boolean controls, the node does not work.

  Not such a problem in LV 8.6.

  Am I missing something? Is that some 'of use' ? Or just a bug?

  This looks like some sort of problem of indexing with the nodes property as somesort of corrupted installation.  What happens if you just delete the property node and recreate him?

  I filed a digital control and looked at the context menu of the list of the nodes property.  Below value and value (signs) are Visible (which would be a Boolean value) and Xcontrol, that when you bring through the submenus, the first choice is container bounds, a cluster of Width and Height.  If these 2 types of data which are located 2 below in the list match those you found.

  What happens if you take another node in property a few elements upwards or downwards in the context menu?  Fact is happen for other properties, and if so, are thereany properties who agree?

  Here's what look like my property for a digital nodes and I draggged the box up and down to show the natural order of the nodes property.  Notice that I have script installed, so there are a few other nodes property (and the blue box at the top) you may not have.

  

  PS. Verify you the signature.  Kudos button is now moved to the left since the update of the forum.

• Intermittent error 1077 on update of the Boolean property node

  I have an intermittent error disabled 1077 on changing the value of a series of nodes of Boolean property in my program. I'm passing an array of references in a loop For, all the controls are in this VI and it can be classified for these purposes as a first level VI.

  Most of the time that my code works fine, however, debugging my code this morning after any recent change in this part of the code I get errors that I have problems. Any ideas on how to get this past or what is causing it please?

  Photo of part of the attached fault code.

  (Loop on the right is normally recorded shirft, but is not currently facilitate debugging).

  Finally found the problem.

  Because my table of numeric values was so small in width, I saw only a figure because I expect only the width to a figure.

  In one of the structures of the event, I wrote the number 030 instead of 0 for the node property disable result with the above error.

  I learned from this mistake and my paintings a little wider. (This is a similar problem when you forget to look for the possible extra line in a control of the chain).

• Local variables are comparable to the value property of a control or indicator?

  I use the buttons / switches mechanical locking action, event structures and local variables to track the status of my switches.  I used local variables with indicators, too.  Now I see that this could be done via the node property of a switch or an indicator.  Should I use the nodes property instead of local variables?  Should I use "switch" mechanical action and control the State of the control buttons / switches?  I used a mechanical locking action because it automatically reset when it is read, but who pushed me in the use of local variables.

  I know the property values to adapt the data flow model, while local variables might be placed in a sequence structure to ensure the order of execution.

  I just don't want my program all except if it is a correct approach.

  Thank you

  Dark Hollow says:

  Well, I'm changing the properties of user interface in my state machine.  For example, when you push a button to START the TEST, I want to disable and gray this button and activate the button to STOP the TEST.

  No engineer too much. In this case, you can use a single button and label the FALSE case a 'start Test' and the REAL case as TEST 'STOP '. No additional code needed at all. At the same time, you only use the half-Panel space! (and 10% space diagram!)

  Dark Hollow says:

  Another example... I have a couple of dozens of LEDs on the front panel to show the TEST SUCCEEDED.  If I have the wiring all of them, my state machine diagram gets messy.

  Define disorder! In my mind, code is not held together by wire is much messier because it is impossible to determine the order of execution and so program logic. A thread is a small 1 d object. A property node is a significant 2D object. 20 wires are much less messy than 20 knots of property, especially given that each property nodes still hanging by a thread in one way or another!

  In order to reduce the number of threads, use the most appropriate data structures. Instead of a few dozen sighted use a single Bay of LED. A single wire! Keep the table in a shift register and update alone LED as necessary by using "replace subset of the table".

• How to enable and disable the part of the "control panel".

  I want to know if part of the control panel can be turned on and off by an external action, to use the mouse or a Boolean variable. Someone has an idea that help color? Thank you

  You can disable cookies by using the node property and ownership "Disabled". You can create a tab control and disable the entire tab control that will disable all inside of it.

  To do this programmatically, set up your code with a structure of the event and create an event when the user changes the value of a button or click the mouse.

  See the example I did:
