Need to Print Screen the Front Panel

Hey guys, as the subject says, I need to capture the front panel of the Vi every time it runs (without using alt-printscreen or any other applications). Can I do this using LabVIEW 8? Thanks!

Here's a code example.

  • HOW TO GET OSCILLISCOPE "Screen Capture" ON THE FRONT-PANEL?????

    Hi All,
    I have a lot of parameters displayed on the Tektronix Oscilliscope like the trigger level, the frequrncy,CH1 T/Div and probably many others along with the Waveform(obviuosly!).
    I need to capture this exact oscilloscope screen on the Front Panel.
    Kindly help me out in this!,
    regards,

    This one has the driver for your "Tektronix 2440 Oscilloscope" and the oscilloscope can be hooked up to the computer via the GPIB port. THe details are given in the link....
    If the link does not work I have attatched the drivers.....

  • How do I get the front-panel to pop to the front of the screen?

    I have a program that is reading in some network files. When a certain part of the file has been changed I want to pop up the front panel and blink the changed area. The blinking is easy and I can get the VI to pop to the front of any other running LV stuff (using the IsFrontmost vi property) but I need the vi to pop to the front of the entire screen and whatever else is running (Excel or the such). Any ideas on this? I'm doing the development on LV 6.1 on Win2k.
    Thanks,
    Gary

    Hi Gary,
    There is one thing I think you may have to do. If the window is minimized than it will try to make it topmost but the minimize will take precedence, so you will see the task bar blink and the OS stays in the active/current window. Try to use the "restore window" vi before trying to make it topmost. That should work.
    Also make sure that, the LV window you are trying to restore and make topmost is not superceded by another LV modal window.
    Thats my take, Let me know if that works, for future reference.
    Good Luck
    Mache
    I've tried putting in the Restore Windoe vi and the results are the same. Both of those functions (seperate or together) result in the window moving to the top of the other LV screens only. If I have Word or explorer or anything else open, that window will stay on top and the task bar flashes. Can I use the "move window to front" vi in my main vi to move my main vi's front panel to the front? If not are there any ways to get around this? My program is mostly running in the background but when there's an important change I need it to move to the front and take precedence for a few seconds.

  • How can i print an excel spreadshee​t file by clicking a button on the front panel

    i have designed a vi that logs data into an excel spreadsheet. i want to take print out of the file when the user clicks a button on the front panel. what to do if there is very large amount of data.

    Preet,
    Printing the Excel sheet is just an ActiveX method call to print the worksheet. To add data to the worksheet, you already have the reference, just call a print method. As for handling large amounts of data, that is a vague question. The data will print how ever you placed it on the worksheet. If what you mean is that you don't want to print out 25 pages every time, the print method has options to only print specific pages or ranges. You may want to play around with a sample spreadsheet to learn the printing options. For help on the ActiveX functions, make sure you have the Visual Basic help installed for Excel.

  • Screen capture of the front panel automatically

    I've got a VI that analyzes a data file and outputs a graph, some numbers/notes, and a pass/fail message to the front panel each time we run it. I want to be able to automatically save all that data into one easy-to-access file (no html) after running it, and ideally this would be accomplished by just capturing the screen of the front panel and saving it as a .jpg.
    I've looked up how to do this on the forums and searching the web, but no solutions have come up. I've looked at the "Get Image" method, but that only lets me get the image of one object in the front panel, and not the entire front panel screen. I read something about referencing the front panel as an global, and inputting that into the "Get Image" method, but I can't get that to work and don't know if that's possible.
    Is there a way to make a straightforward automatic screen capture of the VI front panel? How can I program that?  (Manually using the "pinrt screen" function off the keyboard and copying and pasting it won't be feasible for this application).
    -- Thanks for the guidance

    No sure why you couldn't find a reference to it but there is the VI method Get Panel Image.

    Dear all:
    Sorry for so long title.
    I need your help with how to drag the objects and drop onto the front panel.
    Like the LabVIEW front platte, i can choose the objects i can drop onto every where of the front panel.
    Could drag and drop function can satify?
    Any idea?

    What you want to do is relatively complicated and it seems that your knowledge of LabVIEW is relatively basic. I suggest you try searching this site and google for LabVIEW tutorials. Here, here, here, here, here and here are a few you can start with and here are some tutorial videos. You can also contact your local NI office and join one of their courses.
    In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

  • Why doesn't LabView scale my objects properly in the front panel?

    In LabView 6.02 (Windows 2000) I have experienced problems when using the "Scale all objects on panel as the window resizes" option under VI properties. Try the following example: Go to the front panel and draw two arrows (from Decorations), one vertical and one horizontal (make sure they are perfectly straight). Now, resize the window, using the bottom right corner several times. You will soon find that the two arrows become increasingly missaligned and are not perpendicular to each other anymore. The problem gets worse the more you play around with the window size and they will never return to their original state. Installing the 6.02 patch did not seem to help at all.

    Dear Gustav,
    First of all, some objects do not scale whatsoever in LabVIEW. These include refnum controls and text.
    As far as the "scale all objects on the front panel as the window resizes" option goes, you have brought attention to an issue that I will announce to the R&D team. Currently, when you resize the screen, the objects on the front panel are resized at the same fraction of the original size, yet small rounding errors occur. As you move the window around, this small rounding error multiplies accordingly. Once you maximize the window, the small rounding error is translated into a large-scale degree change in the orientation of the (previously) perpendicular arrows.
    What action are you trying to perform that caused this issue? If possible,
    please post some screen shots of your front panel or give me explicit details as to your programmatic goal.
    One thing that you may try in order to prevent this misalignment and orientation shift is to highlight the arrows. Then, click the "Reorder" button on the toolbar and select [lock]. This will lock the objects and prevent them from resizing while the rest of the screen resizes (see attached image).
    Again, I'm sorry if the aforementioned phenomenon causes you any inconveniences, and I will be sure to announce this issue so that preventive changes are implemented in future LabVIEW revisions.
    I hope this helps. Please let me know if you need any further assistance. Have a great day!

  • How can I make a pdf-file of the front panel?

    I like to make a pdf-file of the front panel. Thus I need a vi, where I can input the printer name (as the pdf-printer is not the default one), the vi and the name of the future pdf-file.
    Thanks, Verena

    Try this and if you were to search the forum with "pdf" as the search parameter, you'd find several postings on the same subject. One of them is here and another is here with some email addresses of individuals with existing toolkits.

  • I want to save an image of the front panel, (with data), after every VI run

    When I try to copy the front panel (using a select all), and paist to paint, all the data in the graphs show up as they did after the last run, but the data in the charts dissapear. The chart itself is copied but the data is not. Any ideas on how to solve this?

    This Knowledgebase also has some information on programatically saving VI images
    http://digital.ni.com/public.nsf/websearch/942DAA35C7B35616862565FE005F713F?OpenDocument
    (KB 197BB7VJ if the link doesn't work).
    Note that you don't have to put the code in the VI you are running in order to save it to a file, so you don't actually have to modify your VI. You can just run a seperate VI that uses the VI name from the first one (I've attached a VI which could either be run standalone or used as a SubVI, as well as an example of using it as a SubVI).
    If you don't want to do it programatically you could just hit the print screen button on your keyboard and then paste it into paint and crop off the extra windows stuff.

  • How can I make an area of the front-panel have scroll bars?

    I'm writing a VI that provides many options to the user. The front-panel is large and contains many controls ~130 of them, it's divided up visually to match the workings of the system the VI controls. One particular functional block has very many control options though these are rarely used. I can't fit all of the controls I need onto the screen area I have available.
    What I would like is a way of making an area of the screen with scroll bars on it. I don't need any more than that, just an expansion of the front-panel area I have available. The "Sub-Panel" feature provides the scroll bars. But, a Sub-Panel is a way of accessing another VI, I don't want to do that. I could put the extra controls on the far-left or far-right of everything else and get the user to scroll the main scroll bars at the edges of the screen. The problem with that is that I it would mean couldn't lay out my front panel to match the system block-diagram as I have so far.
    Does anyone know how to do this?
    Solved!
    Go to Solution.

    I know I can show the scroll bars at the edge of the VI. In my case that's not very useful. The front panel shows a block diagram of a system. It's made up of a set of clusters which control various parts of the system. I want to keep this layout because it's very useful in explaining to people new to the system how it works. I inherited that approach from a previous iteration of the program for an older system. The problem I have is that the new system has far more control parameters for one of the blocks. Unfortunately it's one of the blocks in the middle of the block diagram. If it were one at the left, right, top or bottom it would be no problem because the main scrollbars could be used.
    I can use a tab-control, that's my fall-back plan. The problem is that would be abusing the purpose of the tab control. In a tab control each tab is supposed to deal with a group of controls that have a common connection. So, all the things in tab #1 are supposed to be connected in some way and all the things in tab #2 are supposed to be connected in some way. There not supposed to be a way of gaining more screen space.
    The controls I'm dealing with are numeric controls, switches and rings.

  • How to create a cluster, whose elements are all scattered across the front panel?

    Hi everyone!
    I've been designing a front panel, which (I think :-)) feels pretty well when the override switches are scattered all over the screen. Anyway I'd like to process their states in a cluster. I tried pulling them in a cluster in the block diagram, which didn't do anything (actually they hid underneath the cluster). I tried bundling them, but the only way I could do so was after creating a hidden cluster on the front panel and filling it with the same number of boolean controls as I've got override switches.
    Anybody got any suggestions?
    Kindest regards,
    Severin

    Severin,
    You should be able to bundle the elements without creating a dummy cluster. You cannot use Bundle by Name without a control (or indicator), however.
    One possibility, if you need a cluster, is to make a cluster which is bigger than your front panel. Make the background transparent or the same color as the panel. The problem with this is how you handle other controls or indicators which are not part of the cluster. You could put them behnid the transparent cluster, but then you cannot operate the controls and panel updates are slowed considerably by overlapping front panel objects. You may be able to slide them in front of the cluster without embedding them into the cluster by placing them on the panel outside the cluster and using the keyboard arrows to move them. This works for some things; I have not tried it with clusters. You still have overlapping objects.

  • How to synchronize presentation on the front panel to the start of a 75Hz monitor's retrace cycle?

    How to synchronize front panel presentation with the start of a retrace cycle of a 75Hz Monitor, so when a bitmap is presented 100ms, its duration is indeed 100ms on the monitor?

    Hi,
    In the old days (late 90's), we used in port and out port to wait for
    vertical retraces (or even horizontal retraces).
    I searched the web (vertical retrace), and there seem to be lots of
    infromation and tools, like
    http://www.compuphase.com/vretrace.htm
    It uses a simple routine:
    mov dx, 3dah ; VGA input status register
    vretrace_loop:
    in al, dx
    test al, 8 ; bit 3 set?
    jz vretrace_loop ; no, continue waiting
    But to get it working, you need a VxD. Good news is you can download it.
    The also suggest you use WaitForVerticalBlank(), but dx could be hard to get
    working under LabVIEW.
    Please let us know how (and if) you got it working with LabVIEW!
    Regards,
    Wiebe.

  • Is there a way to use the built-in Datalogging and programmatically log the front panel while the vi is running?

    I would like to use the built-in Data Logging feature. There is the "Log at Completion" option, but is there a way to programmatically make a new log record while running? I looked around in VI server and couldn't find any methods that would do that. Currently, I am grabbing all of the front panel control references using VI Server and if there are any changes, the changed values are written to a log file along with a date/time stamp. I'm mostly dealing with buttons, which simply change from 0 to 1 or 1 to 0, so it's not too hard to visualize what was pressed. It works okay for reconstructing what happened, but it would be much nicer to use the built-in fe
    ature because you can "replay" directly onto the front panel and actually see what the changes were. However, without being able to programmatically make a new log, it won't work for me.

    Jake,
    There are several options here.
    I would suggest using your own code for datalogging. The datalogging you are referring to is primarily for debug, and one shot datalogs of front panel indicators (and controls?), not including graphs, etc.
    If you go to the file functions, you will see a menu for datalogging. These functions will allow you to save your data, as you need it, simply, and in a compact format.
    I recommend opening the datalog file, doing all your file operations, and closing the file before the program is complete. There are several examples of this in the examples database.
    Good luck

  • How can I display the front panel of the dinamically loaded VI on the cliente computer, the VI dinamically loaded contains files, I want to see the files that the server machine has, in the client machine

    I can successfully view and control a VI remotly. However, the remote VI dinamically loads another VI, this VI loaded dinamically is a VI that allows open others VIs, I want to see the files that contains the server machine, in the client machine, but the front panel of the dinamic VI appears only on the server and not on the client, How can I display the fron panel with the files of the server machine of the dinamically loaded VI on the client computer?

    I down loaded your files but could use some instructions on what needs run.
    It seems that you are so close yet so far. You need to get the data on the server machine over to the client. I generally do this by doing a call by reference (on the client machine) of a VI that is served by the server. THe VI that executes on the server should pass the data you want to diplay via one of its output terminals. You can simply wire from this terminal (back on the client again) to an indicator of your choosing.
    Now theorectically, I do not think that there is anything that prevents use from getting the control refnum of the actual indicator (on the server) of the indicator that has the data, and read its "Value" using a property node. I have never tried this idea but it seems t
    hat all of the parts are there. You will need to know the name of the VI that holds the data as well as the indicator's name. You will also have to serve all VI's. This is not a good idea.

  • Is there a way to rotate an array on the front panel?

    Is there a way to rotate an array on the front panel?  For example, I want element [0] to be at the bottom of an array that's expanded to show the elements vertically.
    Thanks in advance.

    I do not think that there is any way to make an array control or indicator display that way.
    You might be able to reverse the array, creating an upside down display. If you also need the user to index it, then it gets trickier.  Hide the array index display.  Create another numeric control to look like the index control.  When the value of the new control is changed, subtract the value from the last index of the array and use the difference to index the array.  You may need to adjust by +/-1, so try it to be sure.
