• How to add a record button on the front panel to save waveform data

  Hi, I'm new kind of LabVIEW and I worked on a code for an agilent oscilloscope communicate via GPIB and so far it works well on the collection of these two analog channels one by one, "Not UNLIMITED" but it does the trick (vpp, Vrms, frequency, etc.).  I've added the feature to add data to a .csv file waveform (problem: opens a dialog box until the user gathers all the data.) Solution: I want the user to save the. File CSV whenever he wants to use later on the front panel). I've added another feature to get a snapshot of the curve waveform (problem: opens a dialog box.) Solution: I want the user to save the JPEG file, whenever he wants to take a snapshot ("take snapshot" button on the front panel)).  I work with the agilent hp54645d driver. I have attached my code, if someone can tell me please how do I do this (maybe cabling and structures are solutions do not know). Thank you in advance.

  I would recommend adding a case structure just around the two record VI and a button to check the condition of the structure of each case. If you want a button to control both save functions you can put the two record functions in the same structure of business controlled by a single button. You are right in saying that the loop will cause your code runs until the stop button is pressed or until the stop condition is met. If you are wanting the while loop to stop once the recorded information you can use the button that you use to control structures case to also stop the while loop. I hope this information helps.

• Scan of the computer does not work in silent mode of the button on the front panel.

  The machine is the Photosmart all-in-1 6280 on a network of small size and using the HP Solution Center. Basically everthing works fine, but when I use the button on the front panel to scan a document, it seems necessary to walk to the computer to answer a question about whether I want to scan another document until I could walk to the printer/scanner and press the button to scan the following document. Surely, there must be a way to do the scan run in quiet mode so that I don't have to keep clicking OK on the computer every time? I have already disabled the overview of digitization and the prompt for advanced options.

  Oops, forget all that; now I found the setting 'interrogate analyses' which stood on another branch of the installation menus. That solved my problem

• A button on the front panel reset

  I use a record button on the front panel, in the mode "change when you press on. I have run the VI, then press the record button. After having intercepted the VI, the button lights. How do the button return automatically to the OFF state during execution of the VI next time?

  Set the property to "False" node, it will reset.

• Is there a way to put a button on the front panel only when clicked gives a pop-up dialog box with more information on it?

  Hello world

  The simulations that I create are very simple themselves but are intended to use in the classroom to help students learn more about the proven theory.  I hope to be able to place a 'help' or 'other info' button on the front panel that rises wants more info on theory, they can click on it and a pop up appears with background information on it.  It should also have a second button to close it and return to the main façade.  Can anyone lead me in the right direction?

  Thank you!

  Use a structure of the event on the main vi when the button is clicked, launches a "help" void / vi. On the inside of the Sub vi (with the set properties to load the front when it is called, of course), use another structure of the event to wait until then click on the button of the Subvi, you can return to the main VI. Do you need assistance on using the structures of the event?

• pause button on the front panel

  Hello.

  I try to run synchronous, continuous analog conversion of 2 cards of PXI-6259, and capture the State of the several digital at the same time.  I managed to get everything is configured and working properly, however I have a problem if the user presses the button "pause" on the front panel.

  From what I can tell, acquisitions of data will continue to run in the background (I'm using a task DAQmx and stop was never called).  For my analog inputs, this is not a problem.  However, the digital inputs always generate a ' 200010 - on-board memory overflow error. Due to the limitations of system and/or the bandwidth of the bus, the driver could not read data the device enough fast to follow the flow of the unit. »

  Is it possible to register for an event of user interface that is generated when the user presses the button "pause", so that I can stop the acquisitoin of data before the error occurs?

  Thanks in advance,

  -Rich

  I thought to add my own button "pause" / control, but my users have become accustomed to hitting the pause on the front panel button, and it will be difficult to get them to change.  I guess that the error would remind them :-)

  Well, that's easy to fix - change the appearance of window properties if the toolbar is not visible, while the code runs, and there will be a pause button for your users to click.

  Many of our applications have a function somewhat like this.  My colleague implementation in a very simple way: he put the graphical indicator within a box structure.  Connect a Boolean control "pause" to the structure of the case, and that's it.  Data acquisition runs constantly but will only update the chart when the pause button is false.  This approach might work for you?

• Best way to share/update buttons on the front panel

  Hi y ' All!

  I am a beginner in LabVIEW (2 years experience: 1.5 academic year and a team of the FRC and professionnellement.5 of mentoring as a new graduate in a startup).

  We develop an application using LabVIEW which is intended to be user-friendly touch screen and we have so many front-facing button with which we are dealing. In order to make the code more readable in force and easily scalabe, I will like to know if there is an effective way to process orders from the front.

  To illustrate, let's say I have this UI:

  

  

  The real way we propagte these controls is to create a cluster of the reference of all controls (it's where I wish we had LabVIEW 2012-_-) once unbundle that we need in the appropriate section of the code (means it's a large number of sons everywhere...)

  

  So are there better ways to achieve the same goal?

  Thank you!

  I'm talking about a Controller of GUI in this thread. This can give you an idea.

• Create new vi by clicking a button on the front panel

  Hello. I'm quite new with Labview.

  I have to use an if statement to activate a button (I don't know if it is possible or not in LabVIEW) then when the button is enabled for the user must click on the button (allows the button say NEXT) to close that vi and open an another vi to a specific address. I have need to record anything the previous VI that I just need to close and open a new one.

  Does anyone know how to activate a button to get the right answer to an if statement first and also how to close and open the new vi by clicking this button.

  Thank you very much.

  I think that the seal will help you much further.  I have documented if necessary.  If you have any other questions, feel free to ask.

  I have configured the HP scanning software and added a shortcut. It will scan from the HP Scanner Software, but no analysis NOT of the scanner. The name of the user's the shortcut there. When I hit the button, is said "Please wait" and the Green LED flashes. But it does not scan.

  Solved. Do you have an another clean install and it worked...

• Outsourcing of the controls on the front panel for a panel floating Subvi

  Hello!

  I already found a few similar topics, but I still don't know which is the best way to solve my problem. I will try to describe my problem in detail first: I have a main VI that acquires data from a device and displays these data in a large waveform graph. I have also a few controls on the front panel to control my device. First, I placed all of these device controls (digital, sliders, etc.) as well as the chart inside the front of my main VI. However, due to limited screen space now I would like to make the largest possible graph and so decided to "outsource" some controls out of the main façade of VI to several panels front-end Subvi.

  I would then press a button in my main VI and it would open the Panel before the floating of the Sub - VI corresponding with outsourced controls when required. However, everything must be absolutely transparent. It is important that floating panels to run in parallel with my main VI, that is the main VI must continue to operate. That way I'll have my data constantly updated in the chart in my main VI while I can change some settings of the device through the controls placed in my SubVIs. These changes will be immediately applied (for example as soon as the main VI calls this slot - VI in its main loop).

  It is important to the visibility of the outsourced optional control panel, i.e. If the Subvi front panel opens with the user that it will pop up and the user will be able to change the paramers device using the. But then the user should be able to close the front panel (hide) the Subvi to see the entire chart again without the Panel floating in front of her (of course control values must be maintained when the Subvi front is not visible). Then the new button is pressed in the main VI that opens the dialog box not modal Subvi containing controls and it can redefine new values of device.

  Advice how to do this are welcome. I don't know if I need something complex like VI server or asynchronous screws or I can solve my problem by changing some settings simple Subvi? Thank you in advance for your help!

  Best regards

  How about using a global variable for the VI at VI communication instead of a queue?

  A global variable will, also.  Write you in one place and read the value frequently to somewhere else (in the election). So you can see easily to any value change.  However, mark will waste a lot of time processor.  This is why I have proposed to use a queue or a notification utility.

  Would be the last option that you mentioned, i.e. finish the Subvi at each change of value, I would keep the Subvi front open as needed until things from the user to hide? Or would there be inevitable flickering Panel or any other drawbacks?

  Yes, the Subvi can keep the façade open until the user closes. And there should be no flickering.  The biggest drawback I see right now is that when you expect an event in the Subvi, the mainVI cannot stop without talking to the Subvi to stop.  So you'll need another channel of communication (again a global, a queue, a declarant or an event) to tell the Subvi that she must stop.

• button arrow in front panel

  Hi guys,.

  I want to have an arrow in the front panel to control the operation of a number.

  Which means;

  If I press the arrow key to the left, the number decreases and arrow key to the right, the reverse occurs.

  I found a drawing of arrow under the decorations but cannot change anything with her.

  Basically, the arrow is sufficient to act as a Boolean switch.

  Once pressed, it lights up and the number accordingly runs and stops when letting go.

  I want to have the arrow keys to make the more presentable façade.

  Pls advice me to.

  PLs Note: I'm not using the keyboard to simulate on the front panel. It is purely on the façade.

  one thing you can do. I should work

  1. make a right click button in VI and select Advanced > customize

  2. then a window will appear where you can customize the button.

  3. click on the right button and select Import an image from the Clipboard > decal

  4. it should look like this (attached)

• Disabling the controls on the front panel

  Hello

  Currently, I am working on trying to disable/gray out between 10-20 controls on the front panel when you press a start button and then allowing them the end of the test. Currently I use the property nodes, all of which are connected to a constant of the State in which I want that works perfectly. My question is that there is another way other than having a bunch of knots of padding property to the top of my structure of the event. Ive read where people had Subvi, which has used references to make this same feature, but is there a way of doing things in the block diagram of my current VI? Thank you!

  Need references of your controls on the front panel, so this can be fast, because you can select more than one, and with a right click you create references.

  I have attached a version LV2010.

  Edit: another review:

  Must be created only once these references. Usually, it's comfortable group all the references in a cluster, use this thread through your entire code. This way you can just ungroup references to the actual location, you have to play with, put them in a table and use the above FOR loop to change their properties...

  Like this:

  

• A way to group controls and indicators on the Front Panel and that they can be made Visible or not as a group?

  I would like to combine several orders and LEDs on the front panel in a group in a way that allows me to do the whole group Visible or not.

  I tried to use a Cluster, but it has a side effect that all elements must be inside the controls or indicators, but not mixed.

  Is there any graphic element, like a panel that can contain other controls and indicators on the inside and make them Visible or not as a group regardless of whether they are commands or the LEDs?

  Good suggestions on how to do this?

  Thank you.

  The tab control is still not my favorite, appearance but it's a way fast and effective to show and hide groups of controls and indicators.

• How to make non-visible control on the Front Panel appear at Design time?

  I have a few controls on the front whose visibility is changed (on or off) at run time. The problem is that if I stop the Run time, the visibility of the control remains in the running in design mode state. So I am not able to see or find the control to make changes in design mode.

  How can I make all the visible front-panel controls, or find and make it visible to a control on the front whose visibility has False?

  Thank you.

  It is documented in the help of LabVIEW.

  Hidden front panel display

  
  

  Perform the following steps to display a hidden front control or indicator. You can also hide the indicators and controls on the front panel.

  1. Find the terminal block schema for the object. "If you have multiple devices with the same type of data, right click on the terminals and select visible elements" Label in the context menu. Find the object with the label that corresponds to the object hidden façade.
  
  
  2. Right-click in the Terminal, and then select Show Control context menu if the object is a control or indicator to show if the object is an indicator.
  
  

  You can also use the Visible property to display the controls and indicators by program.

  You can also view all hidden front panel controls and indicators.
