• Police in width fixed in the control chain

  I do it an alignment in the text control and that you want to use "fixed point" or are monospaced, Consolas.

  Font Consolas is very basic fonts in all windows and Notepad and shows the "zero (0)" as you can see the attachment.

  I placed the police for control of the chain, chain control the other police shows that property node has revealed the information provided.

  (I notice that police Labview dialog box shows the correct information.)

  My problem is that police, Consolas, find the Notepad and Windows, but cannot display it correctly on the control of the chain.

  Can you help me how I can check this problem?

• How to accept only 4 or less than four hexadecimal characters in the control chain

  Hello

  I want to accept only up to 4 hexadecimal characters in a control of the chain. I don't want to use the property "hex display.

  How is that possible? I have the string control key down? event event, I tried with the regex [0 - 9a - fA - F] {4}, but then I have to accept, left, right, delete, BACKSPACE, house keys as well.

  I agree with Dennis that you seem to be making life difficult for yourself.  However, did you ask the equivalent (as I understand) "How can I allow the user to type '1', '2', 'Ctrl-A', 'B',"Ctrl-C","D"and get this recognized as the string"12BD".  If you really want to do, here's a way (I was lazy and left the response as an array of strings of 1 4 characters).  I use PlatMods to exclude have any 'change' other key moving downwards, convert the digital Char to a string, then count the letters of acceptable Hex and conditionally, add them to the results matrix, stopping when I have 4 characters.

• How to make the difference between the mouse down events in the control of the chain (click on contour vs click Center)?

  Hello

  I have a control over the chain on my UI and I would like to make the difference between mouse different events, that is to say, to be able to differentiate a click on the outline or the label of the controller vs right-clicking on the Center (between the control in "edit" mode)

  The reason is that sometimes if the user does click not in the Center but in the scope of control, Labview fires the mouse event down but the typed keys are not registered...

  Is it possible to distinguish the two?

  Thanks a lot for your help

  Set the string "update as you type" and use instead a "changed value" event Now, the event fires whenever a new character is entered.

• How can I change the value of a control on front panel?

  On the front panel, I'm doing a complex control that consists of a Slider control and control of the digital inputs. Both controls display the same information and either may be used for entry. When changing value, I want the other control to display the same value.

  How can I change the value of a control on front flap when another control changes the value? I know how to use a structure of the event to detect value has changed, but I do not know how to impose control on front panel to change its value in the block diagram.

  Why do you not use a digital display on the slider, and no code is required:

• How to detect the event mouseclick-control

  I am trying to relax the max property Z on the scale of a graph of intensity to be changed from the front panel.  In the VI attached, I use an increment/decrement control and just detect a value change event (without taking into account the value of the control).  It works very well, even if it's a bit of a hack.

  I want to make them much more functional.  My main question is this: How can I detect an event 'control-click '?  I intend to use this event to change the max of graphic intensity by a factor rather than an additive value.

  A second quick question: on the numerical control, is there a way I can get rid of the number in the display space and leave only the increment/decrement buttons?

  Thank you

  Allan

  Are you talking about the button increase/decrease on a digital control?  I thought you had Boolean separate to increment and decrement. It's hard.  You can't be the PlatMods when using a value change event.  You will maybe make your own controls inc/dec and update a digital indicator rather than use a digital command.

• menu bar popup not working if the focus is on the control of the chain

  Dear all,

  I wonder if this is the behavior expected or if I'm doing something wrong:

  On a Panel, I have a control of the chain; on double click, I opened a file selection box to select a file, then the file name on this control of the chain. After this action, this string is the active control, indicated by the gray frame.

  I also have a menu with some defined keyboard shortcuts bar for example F2. It seems that F2 is not functional, long as the focus is on the control of the chain. It's embarrassing because the typical user action is selects a file and then pressing on Fx. To resolve this problem, the user should click somewhere on the Panel to move the focus to another control. Of course this could be done programmatically, but the extra effort is not to say necessary for controls ring or digital controls. Also in digital controls, I can change the numbers, but even if a digital control is the active control due to the edition of the F2 value works immediately.

  Help is appreciated.

  Thank you

  I think what is happening here is that left double click is also used to highlight the text. So when you trigger the EVENT_LEFT_DOUBLE_CLICK, you're placing the text in the control of the chain and then also accentuating. It seems to be behaving strangely when the two of them occurs at the same time because of the order of the events. You can see that the mouse around when, returning from the file select popup causes the region highlighting to drag over the text. In this highlight mode, you cannot use the shortcuts for the menu. I was able to solve this problem by swallowing the EVENT_LEFT_DOUBLE_CLICK after you set the value of the control.

• Detect the dial needle completed the change of value?

  Hi all

  Is it possible to detect when a needle dial finished changing value?

  I am creating a VI to request a change in working capital.

  I don't want the control unit with a request for every change in the needle of the dial of the swamp so I use mouse events.

  Can I use Dial: mouse upwards and the dial: left mouse to request a new change in working capital.

  However, you can always pass the needle when it is outside of the wheel, which does not lead to a step change request.

  I have attached my VI and any help would be appreciated gratefully.

  Phill

  How to detect the events and update the indicator.  I added "component: Mouse Up ' to update the indicator if the mouse leaves the button before falling from the needle.  This will add a nuisance update when the pane: the mouse upward is due to something other than a movement of the needle, but you can detect that in seeking a change in value on the dial.

  

• Compare the previous values of a control?

  Hello! I am communicating with via GPIB hardware. I'm rebuilding software to control the unit. Unfortunately, the GPIB bus is "clogged" with a lot of almost synchronous calls to the GPIB. In order to solve this problem, I would only request the GPIB, if a control on the front has been changed by the user. For example, to change a constant in time, the user changes the value in the control of constant front of time. An instant more later, a request is sent to display what unit was defined as the time constant. I wish that this request to the device will only be sent if the user has actually changed the value of a constant control of time. All calls are transmitted in time loop. Is there a simple and lightweight way to check if a control value has been changed? Thanks in advance for any help!

  The structure of the event is your best friend here. Use a value for orders change event.

• Is there a way to detect the mouse during the event for the controls within a tab control?

  I need to change the mouse pointer when it moves on controls that are found in the tabs.

  Now when the mouse passes over the tab, LABVIEW does not detect the saperately of controls for the mouse over event.

  Is there a way to do what I intend to do?

  Your problem is with the Panel.Controls [] property. It does not return the controls that are inside containers (tables, tabs, groups) and returns only the container itself. As illustrated by Sam, if you want the references to the controls in the tab, you must get the references to the pages and get the controls on each page and add them to your original table and do this recursively.

  You can either write a VI to do this (or search for it. There was posted here screw that analyzes recursively the FP for all control references) or everything just statically for this control a tab and move. There is also a VI delivered with LV that can help you with this, but I suggest that you not use, because it will be difficult to operate if you generate an EXE file.

  And I also recommend the Tool of Capture of Code.

• Button, which initializes the values then releases control of more Boolean values

  I want to create a button that turns on a series of other buttons, but then releases the control to allow individual switching. The problem is that for my project I need to run the labview file continuously so when I change a control to true switch it keeps the value of the other true Boolean values. For example, I flick a switch to turn on all the lights at the same time but want to and then later have the power of the special lights individually. Then also have the option to turn off all the lights again with a click of a button. I can't understand this. I don't have much so far, sorry for that.

• Set the value of cluster control in secondary school

  Hello

  Is there a way to set the value of control from one cluster to a high school?

  I enclose my screw in LV8.0

  Charly

  If you have a reference to the VI being put into secondary (which there or it is not in the secondary, right?) you can use it to get a reference to the façade of the VI. This in turn will allow you to read an array of references to all the controls and indicators on the front of the Secondary VI. Cross this table by looking at the text property of the label: for each reference in the table until you find the one for the control of the cluster.

  Now, use the specific function to more class to convert reference generic control of the pole to a cluster reference. You can use it to get an array of all the controls within the cluster. Now, go through this table by looking at the text property of the label: for each reference in the table until you find the one for control quevous want to set and you are there...

• How to ensure that the value of a control (for example double) initializes the last value when the VI has been closed?

  I use a cluster as a control. I would like to double in this control to automoatically values to fill their last values set when the VI is opened or accessed for the first time. It would be great if someone could point out for me. Thanks in advance!

  In my opinion, the configuration files are the easiest method and the best.  Simply save your last values to the file when your code ends.  At the beginning of your code, to read the file and fill in the controls with the values read.  With the configuration files, the section name can be the name of the cluster, and key names can be control names.

  I know OpenG has some pretty nice to do, but I prefer to use the native functions OR when I can.  When porting to a new system, there is no need to copy any additional screws library (OpenG library).  The native DV come with Labview.

• Display the contents of a text file in the control of the chain without changing the format

  Hi all

  I need your help!

  Planning the content of the text report file in labview control chain of the GI.

  When I read the text file and update the chain control, alignment of text was not appropriate.

  but when I open the same text file in Notepad, alignment looks good.

  You experience the same problem before.

  Just use a .net textbox control to display text, instead of the string of LabVIEW.

  There is NO need to re - format the string.

• Send the name and the value of the control to Subvi

  Hi all

  I am trying to send the names and values of the controls to a Subvi.

  I know that I can check out the name and the value of the control by using a property node, but I was looking for a way to make is easy for the programmer to use.

  I think some sort of bundle function, it records the name and the value of the control, but I would like the programmer to be able to connect a random number

  controls to the Subvi without having to specify the number of controls Anywhere.

  I know there is stuff in labview configuration file, but it seems a bit more complex, so what I want to do.

  Also, I know that I can use the OpenG toolkit, but I will not use additional LabVIEW modules, as this VI may run on several different computers.

  I hope I made my problem clear enough!

  Good day

  Concerning

  Tommy

  What, creating an array of references to the command.  On the hand, you will need to fill the table with control references that you want to send to the Subvi.  In the Subvi, use a loop For with indexing to get every reference, and then use the nodes property to get the name and value.
