i tried this using panel bounds property of front panel
using height width of tab tried to set position of tab
but if the reference 0,0 on front panel is changed the tab goes to out of sight

I want to publish my data using datasocket connection on the net and I want to use Front panel binding. Can I?

I want to publish my data on the net.
I want to use front panel binding and I do not want
to write the code. Can I do that. What should I modify
in my datasocket server manager. The other question is, When I open my VI, I want to open automatically my DataSocket Server. My english is bad. When I open the LabView I also want to open my DataSocket server. How can I do this?

To use datasockets to publish data to be accessed via the web, see the following document.
http://digital.ni.com/public.nsf/websearch/F58A6C2DAAADECB68625672400636145?OpenDocument
This document explains how you can create an interactive Web page with which users can view data from a remote acquisition application without the common problems of a client-server application. You use the Measurement Studio DataSocket control and Microsoft Visual Basic to create a software component that you can insert in a Web page. You then use that Web page to read, write, or share data with other applications across the Internet.
If you want to publish data but do not want to write any code, you should consider the web publishing tool available in Labview 6.1. This tool allows
you to create a webpage to be published from the the LabVIEW webserver on your machine. See the following link for more information on ways to easily publish to the web from LabVIEW.
http://zone.ni.com/devzone/conceptd.nsf/webmain/E4E311FA046EE24586256B1F0074F39D?opendocument
As for starting the datasocket server when you run your VI, you can use the 'System Exec' VI to run the application. The exe to start the server is located in the following directory:
C:\Program Files\National Instruments\DataSocket\cwdss.exe
I hope this is helpful.

Adjust front panel to screen size and re-position objects on different systems automatically

Hello, i have designed a vi that contains 5 led's placed at the 4 corners and center of the front panel which occupies the entire screen. However, this vi is to be used on different systems having different screen sizes. But on every screen, i'll need the front panel size = screen size and the led's to be placed to the centers and corner of this new screen size automatically without any manual operations and positioning bieng done every time. Will the resize option perform this task completely or do i have to go for some other techniques?

As far as I know, what you want is not easy to do but it is doable but you have to programmatically do it (no Labview setting). Here is an example for only 2 LEDs but I suppose that you will be able to make it work for your other LEDs.
This VI maximizes the front panel and then positions the 2 LEDs in the center and top right corner upon running. The LEDs are positioned according to their own top left corners, not according to their centers.

How can i open front panel of a vi and run it

Hi
I have a vi that i call multiple times from another vi, however i want it to open the front panel on some calls and not on others. What is the best way to do this?
I have come up with a way and was wondering if this method was okay or is there another method that might work better escepcially since i am eventually going to create an application out of it and hope that no problems pop up then
Unititled 1 calls Untitled 2 where with one call it opens and runs Untitled 2 while with the other call it simply runs untitled 2.vi
What I did was i changed untitled 2.vi window appearance to dialog but i deselected the show front panel when called, so by simply calling the subvi form untitled 1 it works. Unititled 2 runs but does not open
Now with another call i want to open and run untitled 2.vi so by looking the attached vi you can see what i have done
Again if there is a better method that would make my vi's more efficient i would greatly appreciate it.

What you did, in theory, is the correct way to do it. However, you should move the front panel open and close into Untitled2.vi and have a boolean input as to whether to show the front panel or not. This way, your calling code is cleaner, and you don't have to reproduce the code everytime you want to call the subVI and show the panel.
If you were to use Untitled2 in another project, then you woud have to go back and look how to implement the showing of the front panel in your other code. If later, you were to decide you want that VI to be maximized, then you make one change in the VI, and not in every place you ever call it showing the front panel.

I do not own an adobe product and want a one-time payment licence for students and teachers, what should I get?

I do not own an adobe product and want a one-time payment licence for students and teachers, what should I get? There are so many licenses to choose from and at least 3 lightroom licenses for students.

If all you are looking for is Lightroom, I would suggest going to your campus computer store. The computer store where I worked had Lightroom in stock. If your store doesn't have it in stock they can order it for you. There is really only one Lightroom 5 license that comes with the standalone version, student or otherwise. The program is identical either way. Licensing for the creative cloud is handled through the web and the payment method, But you aren't concerned about that.

Problem : controls & indicators not updated when programatically open Front Panel

Hi,
I have a strange problem when I want to progamatically open the front panel of a sub-vi: for some sub-vis the controls and indicatores are correctly updated while for others they are not (ie the controls show outdated values).
I have created an example here that illustrate this. The 2 sub-vis are *exactly* the same, but only one shows updated controls when I open it (with the sub-vi previously closed of course).
How is that possible?
What do I have to do to have the controls updated to the last value of the *last call* when I open the sub-vi?

Honnestly, I would not bother people on this forum for such a stupid mistake.
And I also expect people to know how to run a VI....
And to play in your game, you forgot -3) Turn on the PC, -2) log in windows, -1) open labview...
Well, I DID run your VI and everything worked just fine, however I no longer have LabVIEW 7.1 so maybe your observation no longer applies to newer versions. It could also be because they were just upgraded as Ben noted. I did not study it in detail.
And Yes, as Ben noted, invisible VIs don't get updated for performance reasons (and not to waste extra data copies for the controls and indicators). LabVIEW is typically smart enought to update when needed, e.g. if the subVI tries to print its panel, etc.
I guess you haven't been in this forum for too long, but since controls can easily be operated in edit mode is is absolutely important to mention at which step you run the VI. (try to operate your controls with the computer turned off and you will see that it is not that easy ). Also if you have been programming for any length of time, you should know that stupid mistakes happen all the time (at least to me and Ben ). It is much easier to weed out the stupid mistakes with a quick question&answer than to spend hours searching for a deep and complex solution.

How to save settings in the front panel to different files and retrieve it later?

How to save the front-panel controllers' settings to different files and retrieve it later?
What I've archived is the "Save Settings" function, but when trying to "Reload Settings", I can only retrieve the saved data to front-panel indicators, but not the controllers!
Can anybody give me some advises?
Thanks in advanced!
Charles Lu

Hi
Just write the retrieved data to a local variable (but make it writable first) or property node of the controls.
Hope this helps.

Front Panel Bank of Switches and related indicators

I am designing a test system. I would like a bank of switches on the from panel to turn individual test cases on/off. I've figured out how to do that. And I can do individual banks for the indicator (pass/fail) LEDs and the numeric test result field. But, I'd like to tie them all together. I'm guessing I should start by using a cluster rather than an array. But how to I get the various banks to act as a single group?
As I have it so far, I have a back of switches and a bank of indicators (of switch status) for just playing around. The indicators do not line up with the switches. I'd like a 1-to-1 correspondence for the operator's ease of use. When I use "properties" to expand the indicator bank, it won't take the number. It is internally limited somehow.

I've got an array of clusters now. Much better, but not there yet.
In the example provided, all of the indicators are labeled "T1". I have the same issue with my implementation. Change one label and it changes them all. I would like to see "T1, T2, T3, ..." but cannot find a way to do that. Also, I'd like each type in the cluster to be labeled at the head of the row or column on the front panel. I can do this by brute force (just create a text field and plop it next to the array. But I figure there has to be a more elegant solution. One that ties the pieces together.
Any thoughts?

How can put on the front Panel the Bolean controll to activate stack plot2 mode?

In the properties of Waveform Chart there is the possibility to show all charts in one monitor or the Stack Mode Plot. Can I put a bolean Controll to use this stack plot in run time by Control Panel?
Thanks,

You can't change between stacked or overlay mode at runtime. You could use two different charts and make one or the other visible/invisible.

Possibility of Having GL Control while making Cost Centre PR

Hi Experts
I have one urgent requirement..i.e. at the time of Cost Centre PR creation user should be restricted to enter only selected 2-3 GL accounts. Please suggest how can i restrict GL account at the time of PR creation.
Regards
Ajay Goel

Hi,
   In standard, you can default the GL based on the account assignment category - using the account modifier maintained against the account assignment category in OME9 and the OBYC config for GBB - <account modifier>.
   If you want to restrict the allowed entries for the GL with few GL's then there is no option in standard in MM side as of my knowledge. You may check whether you can use different field status group for the allowed GLs' (FS02 and OBD4) and then maintain different field selection for the field status group same as the field selection for the account assignment category - I didnt test the option - you may check the same.
   Else, you may go for development. If you are going for development, you may create a custom table and maintain the account assignment category and the allowed GL's - you can write logic to check the account assignment category, entered GL and the ztable and issue message accordingly.

Front Panel Controller SubVI?

Here is the scenario, I have a main VI that uses an event structure to call various other SubVI's depending on what control is pressed and to update the front panel accordingly. The front panel of the Main VI is a Tab Control with ~25 controls total. As you can imagine, some controls should not be enabled until other events happen. For example, I have a menu ring called "Report Type" of which you can choose 'HTML' or 'Send to Printer.' Next to this ring is a boolean control called "Open in Browser?" , I want to only enable this boolean control only when "Report Type" is set to 'HTML.' Likewise I want both the "Report Type" and "Open in Browser?" controls to be disabled if the user has not hit the "Download Data" control to get data from the RT Controller (otherwise there would be nothing to report.)
These are just a few examples of what I need to do, I have been adding 'Disabled' property nodes throughout my event cases but it is becoming very unwieldy and making my block diagram quite cluttered and hard to understand. What I want to do is have a 'Front Panel Controller SubVI' of sorts, of which I define about 10 or so various states the front panel can be in and pass that state to the controller SubVI which in turn disables/enables controlls accordingly. This idea sounds good but so far the implementation seems pretty bad. I was hoping I could just make a cluster of control references and pass that into the SubVI but LabVIEW 8.2 doesn't seem to allow me to wrap up references in a cluster. This has forced me to use VI Server to get the references. What I've been able to come up with using VI Server works, but I can't believe its the most elegant solution. Basically, for each of the possible states, I iterate over all the controls in the front panel and have a case structure for their Label Text which determins if that control should be enabled/disabled for the given state passed in. Also, for some reason it seems that it is not grabbing references to ALL of my controls. There is a menu ring control on the front panel that isn't in the Controls[] array. I should mention that this particular Control already has a reference node created for it that gets passed to a SubVI, perhaps this is why its not found in the Controls[] array, but this doesn't seem to be very intuititve, or documetned for that matter.
<a href="http://tinypic.com" target="_blank"><img src="http://i37.tinypic.com/fjgwtv.gif" border="0" alt="Image and video hosting by TinyPic"></a>

Thats a very good idea, although I'd probably want to put a case structure around the disable property node and have it only change value when the search array function does *not* return -1, otherwise I'll be disabling things I might want to maintain in an enabled state.
Just before I read your post, another thought came to me and that why use a SubVI, I could just use a parallel loop with queues to send back state information. Since queues can be blocking, this would not negate my event structure. I could combine the idea you gave me with this architecture. Thanks

Is there a way to disable all vi front panels in Teststand?

I don't want any vi front panels to appear while my Testand program is running. My application uses a lot of vi's and I'm trying to avoid having to reset the front panel properties for each one. Is there a single option somewhere in Teststand to do this?
Thanks.

Hi kevmi2ca,
One could uncheck the Show VI Front Panel When Called box in TestStand for each VI call, if it were checked. There is no other control in TestStand to modify the Front Panel behavior of all VI calls.
This would be a great product suggestion to make at http://sine.ni.com/apps/utf8/nicc.call_me.

Front Panel bounds on secondary monitor

Hello!
I would like to display some elements of the front panel on the primary and others on a secondary monitor. So I decided to make a subvi from the elements I wanted to show on the secondary display.
It nearly works, but I would like to have fullscreen on both of the monitors. Unfortunately if I change front panel bounds to be written in the attached subvi, it shows up on the primary monitor. If I leave front panel bounds to be read it works with the secondary monitor.
Could you give me some advices how to solve the problem?
Thanks!

Dear VampireEmpire,
One way you can do it is to create 2 SubVIs (each with the specific indicators etc, then set the Window Appearence of those VIs Custom, and check "Show Front panel when called"
If you are in a VI, press Ctrl+I, or right click on the icon of the VI on the front panels upper right corner, get VI Properties and navigate to Window Appearence.
In each of these VIs use the Invoke Node :
VI Server Reference (This VI), --> Invoke Node --> Front Panel --> Run-Time Position --> Maximized, and wire monitor number 1 to the primary and 2 for the secondary. Use for example a while loop, and if you want to terminate only one of the VIs at Run-Time, remember to Close the Front Panel (Invoke Node), and the reference.
Then create a 3rd, VI, call it a wrapper, and insert the two VIs to be called. When you run this wrapper, you programatically call the other two VIs front panels.
I have created a little example how to do it. Please find the attachment and tell me your experiences.
A more sophisticated way to do it would be to programatically open the references from the main.vi, and Open --> Run Time.maximize in a while loop --> Close the front panel in the caller.
