Ricardo,
The simplest - set Vi setting->Edit Build Settings->"Remove FP" to YES in
App. Builder.
On Linux you can send FP to any host X server or to any local X display
number, which you want to have as a background, from the command prompt
like: -display:xxx You even don't need X running (but should
have X installed!). Read Xserver mans for details.
Also, there is a way of using virtual frame buffer X server, but I didn't
tried it yet.
Hope this helps a little.

I want to print the front panel without all the header stuff while the vi is running

I want to print the vi front panel without all the header information that Labview puts at the top. I want to do all this while the vi is running by pushing a button.

One option is to use the the 'Print VI to Printer' method. Beware that invoking this method repeatedly with complex front panels has caused me graphics problems in my VI's display that persist until the development environment or the built .exe app is exited and re-entered.
See: http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=135&HOID=5065000000080000005F5A0000&UCATEGORY_0=_49_%24_6_&UCATEGORY_S=0&USEARCHCONTEXT_QUESTION_0=spaz+print&USEARCHCONTEXT_QUESTION_S=0
NI has confirmed this to be a bug in 6.0x and 6.1 and has indicated that it will be fixed in the next version.
I was forced to fall back on the Append Front Panel Image to Report.vi in the report toolkit. Which does not produce printed graphs of as high as quality as the Print VI to
printer method.

I want to control the front panel of a lab View program with C code??

I want to be able to run lab View via Corba. So I need some way to control my lab Vew programs with C code. I really hope this is enough INFO.

Hi Mikey,
As mentioned by the guru more details would help us help you.
Do you just want to start the LV app from Corba?
Do you need to specify start-up value for the LV app?
Do you want want Corba to Fiddle with buttons and controls on the FP of the LV app?
Please outline your "dream" and we will let you know what is possible.

Put the front panel of a vi to an ftp server

I have made a vi and i want to put the front panel of it to an ftp server.
I tried to do this with FTP Put File VI but I didn't manage to do that.
I think that the wrong part is at the remote path, because i don't know what to write.

I don't quite understand what you're doing. Where is D2_v18b.html being generated?
Your code is a mess. You have way too many local variables (in several spots I see you write to the indicator AND to a local variable of that same indicator!). I also see numerous race conditions, which means your code is unlikely to work as you think it will. I also see lots of code duplication, which means you should be creating subVIs. I would guess you have a background in text-based programming. I'm certainly not going to rewrite your code, but I would suggest you do, and you should look into an application design patterns like a state machine.

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

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.

Hi. I want to build a GUI based on several windows appearing following a certain sequence. How can i create different windows in the same VI? Also, i want the front panel of a subvi to appear when i run, how can i enable this.Thanks

Having several windows appear ...

Hi,
You can't create several windows for one VI. But you can use the "Tab Control" and change tab's in the program. Or you can use sub VI's and show ther front panels.
To show the front panel of a sub VI you have to open the VI you want to show and select "File->VI Properties". In the VI Properties window select Category "Window Appearance" and click Customize...
In the Customize Window Appearence window, here you can set a number of attributes for how the window will appear, select "Show front panel when called" and "Close afterwards if originally closed" click OK and OK and save the VI, done.
Now the VI front panel will appear then you use it as a sub VI.

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?
Thanks,

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.

There are so many things wrong with this VI, I'm not even sure where to start.
Hard-coding paths that point to your user folder on the block diagram. What if somebody else tries to run it? They'll get an error. What if somebody tries to run this on Windows 7? They'll get an error. What if somebody tries to run this on a Mac or Linux? They'll get an error.
Not using Read From Spreadsheet File.
Use of local variables to populate an array.
Cannot insert values into an empty array.
What if there's a line missing from the text file? Now your data will not line up. Your case structure does handle this.
Also, how does this answer the poster's question?

Can I Run a labview application in a hidden window (i.e. I don't want the front panel to pop up in this Labview created EXE)?

I have a executable labview 6.1 program with a front panel. The front panel pops up every time I run it. Can I force the program to run without popping up its front panel.
Thanks in Advance

If you're using MS Window, you can use lvwutil32.zip to hide the front panel. lvwutil32.zip can be downloaded from NI site.
Or you can move your front offscreen, so that user can't see it. And save your vi. When you run your vi again, it'll popup at the offscreen position. NI uses this trick to hide windows from LabVIEW users. You can also set front panel size to 0.

Manually controlling the front panel without a keyboard

Hi all,
In my application I constantly switch the keyboard and the mouse between two computers (using a KVM switch), but would like to continuously be able to control a numeric control on the front panel of one of the computers (running LabView 6.1). Even if I wasn't switching, the use of the keyboard is awkward, since the control needs to be fairly effortless, quick and smooth. After searching a bit for a knob/wheel/dial type of controller, I was only able to find the new PowerMate (Griffin Technology) as a reasonable candidate, and have yet to purchase and try to integrate it. I'm also not sure how it will work with LabView.
Am I overlooking a simple solution?
Anyone have some experience with the Pow
erMate?
many thanks, Shy

Another option: Create a simple TCP/IP application in VB or LabVIEW to
control the control.
That is,
Monitor for incoming TCP/IP data in the VI with the control.
If on your other computer you wish to make a change, just use your
little application to do it, and send the value to the main app.
Very cheap to do =)
Another option 2:
Grab the available Parallel Port digital interface design specifics for
labview. Create yourself a simple binary switch interface. Assign 4
bits for up and 4 bits for down.
That is,
sw1 = -10
sw2 = -1
sw3 = +1
sw4 = +10
Read in the digital input from the parallel port and increment your
control accordingly. You can obviously assign any values you want to
the digital inputs.
Hope this helps guide you a little bit!

How can I display a changing variable in a subvi on the front panel of the main vi as the subvi is excuting

In the document attached the vi on the right is sub to the vi on the left. On the subvi on the right the variable "Field Reading" is continuously updated on the front panel of the subvi as the "for" loop is executed, but only the last value of the variable is updated on the main vi front panel which is what is expected. My question is how can I display the changing value of "Field Reading" on the main vi front panel as the "for" loop in the subvi is running?
Thank you.
Solved!

Hopefully I can explain it well enough. It really is simple.
1) Create an empty global variable and call it something like User Interface References.vi
2) For each and every control and indicator on your front panel, right-click and select Create/Reference
3) Place these references wherever you like (I use a series of Event cases to perform my initialisation and these all live in one of these event cases). They can be placed anywhere in the main vi.
4) For each of the references, right-click and select Create/Indicator
5) Moving to the front panel, Cut all the indicators and Paste them in the global variable (eg. User Interface References.vi)
6) Moving back to the block diagram, wire the global variable to each of the references and select the same named global variable.
All the hard work is now done (until you add another user interface terminal). You should now have something that look as shown below, [except the reference labels would be to the left (not sure why the snippet put them above)]. In my latest program I have 82 references!
Done. You can now access all your front panel controls and indicators anywhere in your program as shown below.
You can just select Value in most cases, but in this particular case I wanted to fire off an Event to do some things (log the alarm) as well as just update the value. So, this is another bonus with the method.
Hopefully this all makes sense. If not, let me know.

How can i print an excel spreadsheet 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.

Is there a way to create a button on the front panel that would automatically open the txt file data is being stored to?

I am saving data read from FieldPoint to a .txt file. Is there a way to create a button on the front panel so that when the user pushes this button it automatically opens the .txt folder in notepad? I want to bypass the user having to find the file in the computer in order to open it.

Hi jem,
I suggest that you break this up into three seperate questions and re-post to this list. That way you get more ideas from others that may have better insites than myself.
Re:the sysexec
The Sysexec will allow you to execute a dos command. This is the equivalent of going to
Start>>>Run
What you should do is find the proper DOS command sysntax that is required to open a text file in notepad or your favorite editor. Once you know what a good DOS command is, you should pass that string to the Sysexec.VI. The Sysexec has an input that allows you to choose if the code waits for the command to complete or if it should just start the program and let it run in the background. Sysexec will open its own window to run the command you speci
fiy.

How do I input data to a table on the front panel and stop the program immediately as button is pressed?

What should I do if I want to display on the front panel in real time the values from Polarizer #, P1, P2 and the last calculated value (P2/P1 * 100) called T% in a table or some graphical representation like that? What would I have to do? It could just be Polarizer # and T% if that would be simpler. I just want to let the user know the values in a list, spreadsheet or table as they go. One last thing is that I would like to be able to stop the program at any point in time as soon as the stop button is pressed. As of now, when the button is pressed it goes through the iteration currently in progress and then one afterwards. I want the program to end as soon as the stop button is pressed no matter what sequence it is. What can I do to achieve this? Could you give me an example or modify my program to show me this.
Thanks,

Put a single frame sequence structure around your stop button and then wire from the error cluster going into the error handler to the edge of the sequence structure. Now your code will stop at the end of the current iteration. To see why this works, watch you code execute with execution highlighting turned on and review the section of the manual talking about "Dataflow".
