How do I center and/or maximize the front panel on every event?

Hi,
So basically I have a little issue with trying to maximize and then scale back a VI's front panel every time a user selects a different option from a ring control.
So far i've been using the LVWINUTIL.LLB and the provided window size vi to set the size I want on ring selection change which works fine, but as far as centering the VI goes, the method I'm calling only works the first time. After it maximizes and I select a different option on my ring control which is linked to a case within a while loop it simply resizes to the size i set which is correct but when I got back to the ring case which is supposed to maximize the front panel again, it doesn't do it. Centralizing the FP also only works once.
I'm using FP.Run-Time Position.Centered to try and center the VI....only works once. I do understand that this might be the desired behavior since the name is run-time position meaning it'll only do this when the VI is first run, however I need this to happen more then once, how can i do this? Thanks...

How did you center the FP?
Their a method that should work time after time.

Is it possible to change the font style and size of the front panel title?

Can you change the style and size of the Front Panel Window title? I seem to have no luck. I seem to be stuck with only 1 font/style. I would like to use a superscript for 1 of the letters in the title. Is this possible? If it isn't this would be a nice feature to have in the future. I am using LabVIEW 8.5.1.

Things like the window title font is a function of Windows - not LV. You can change it globally, but not on a window by window basis.

How to: display large error note in the front panel?

hi guys,
When "error out" has an error, I would like to display HUGE RED TEXT in the FRONT PANEL saying: "STOP, ERROR DETECTED!" )
How to do that?
Thanks for your help.
Solved!
Go to Solution.

Place an indicator on the panel. Set the text to HUGE and RED, and set its value to "STOP, ERROR DETECTED!". Make it not visible. When you get an error, use the "Visible" property node to display it.
To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.

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 do you control LED lights on the front panel to identify the number of steps a stepper motor has taken?

I am controlling a stepper motor that is coupled with a valve with four outlets (using an Arduino). I've got a general understanding of how to control the motor, but I want LED lights on the front panel to light up that indicate which outlet the valve is currently at after the steps are taken. The method I'm thinking about involves a lot of repetitive code. I'm not that experienced with LabVIEW, I'm assuming I need some sort of loop structure but I don't know how to set it up in order to control the sequence of the LEDs. I've attached my current block diagram for a visual aid if needed.

I was thinking about using the Stepper To Go and Stepper Write functions four separate times, using the same constants for the steps each time since the distance between each outlet is equivalent. The only difference would be what's connected to the "steps remaining" node, which would be the function that activates one of the four LEDs (if that makes sense). I was thinking that doing it this way would be a little counterintuitive since the only thing that needs to be changed is the LED indicator.

How can I view acquired images on the front panel?

Its pretty simple, go to Edit>Import picture from file (browse for your .jpeg/.bmp/.gif etc file)
again Edit>Paste
hope this helps.

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 to/Is it possible to get the front panel's VI icon?

Hi
I want a sub-vi to get the front panel's VI icon image of other VI,
example, the subVI can have the image return based on VI refnum, is
there any function to do this? I try to search the "Application
Control -> Property Node" and could not find any of it.
Thank for any suggestion.

How much it cost to update bb9810 and to change the front panel

i went to various service centres for updation of my phone's software but everywhere they are charging more than 500 and i have my phone in warranty period when i informed it to them , they said i have to leave the phone for 1 week , i dint get that how can it takes 1 week for software updation .. please help

Hello,
Every shop controls their prices...no one here can tell you if those prices are good, bad, or otherwise. But, you can conduct the process yourself. The simplest way is to, on a PC (you cannot do this on MAC):
1) Make sure you have a current and complete backup of your BB...you can find complete instructions via the link in my auto-sig below.
2) Uninstall, from your PC, any BB OS packages
3) Make sure you have the BB Desktop Software already installed
http://us.blackberry.com/software/desktop.html
4) Download and install, to your PC, the BB OS package you desire:
http://us.blackberry.com/support/downloads/download_sites.jsp
It is sorted first by carrier -- so if all you want are the OS levels your carrier supports, your search will be quick. However, some carriers are much slower than others to release updates. To truly seek out the most up-to-date OS package for your BB, you must dig through and find all carriers that support your specific model BB, and then compare the OS levels that they support.
5) Delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML
6a) For changing your installed BB OS level (upgrade or downgrade), you can launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC.
6b) Or, for reloading your currently installed BB OS level as well as for changing it, bypass the Desktop Software and use LOADER.EXE directly, by proceeding to step 2 in this process:
http://supportforums.blackberry.com/t5/BlackBerry-Device-Software/How-To-Reload-Your-Operating-Syste...
Note that while written for "reload" and the Storm, it can be used to upgrade, downgrade, or reload any BB device model -- it all depends on the OS package you download and install to your PC.
If, during the processes of 6a or 6b, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:

How to display some html code in the front panel

Hello.
I am trying to properly display a few lines of html code in some kind of indicator on my front panel.
I was trying to use an ActiveX container with MS IE in it, but all the methods I find are to make it navigate to a given URL. I did not find any method or property by which I could give it some html code and it would display it.
Anybody know of a way to do this? It does not have to be using ActiveX or MS IE.
Thanks in advance,
Alejandro

Here is a simple way using the activeX that I have embedded in some programs in the past. You will have to call the file path to show the file.
Hope this helps some.

Is it possible to sort the controls and indicators on the front panel?

Programming events would be much easier in an application with lots of
controls and indicators, if there where a means to sort and group them.
Is there any means to do so such that you see a sorted list when choosing the control that triggers an event etc..?

I am not aware of a way to sort the list of controls (that are listed in the edit events dialog) by name. They seem to be sorted in the order they were created.
I agree, sorting could be useful for large VIs.

How do I print a part of the front panel?

I am interested in printing a part of my front panel as one page instead of printing the entire front panel. Does anyone know if this is possible? Thanks!

Hi Nes,
This is the second time you are posting a variation on this question.
I was about to so NO YOU CAN'T...
but then I thought...
It is possible to print just parts of a front panel but it is a lot easier to do the things others have suggested.
If you really want to print just a part of the FP you will have to do a lot of coding and the GUI will do some strange things in the process.
I will outline the process and leave the code as an exercise for the reader.
Using property nodes determine where on the FP the objects of interest are located.
Again using property nodes, move the objects around on the FP so that they are grouped together and sized such they fit on a printed page.
Using property nodes adjust the screen size origin etc so only
the objects of interest are now visable.
Using.....nodes print only the visable part of the screen.
Using....nodes put everything back where is was when you started!
Like I said, this is not easy.
The simplest solution was suggested by BJD who said group the objects of interest on a tab page, use an invoke node to get the image and then display it on the FP of a sub-VI set to print on completion. That method will let you quickly add new interesting objects to the print out without having to change the sub-VI.
Trying to help,

How to send 20 individual pictures to the front panel ?

Hi LabVIEW experts!
I have a lung simulator which I connected to the Ni 9205 and could read voltage from. I wrote the program and it works well. I want to use this program for taking an exam of some trainees. Now I have a problem. I need the trainees to look at the graphs and when they want additonal information by pressing a button, a picture of an xray or lab data related to that patient shows on their monitor. Case by case is different. I have for example 20 lab data from different patients with their xrays. How can I control the trainee program to send a picture which is related to that patient?
Thanks.

Yes.
You just need to have your LabVIEW code programmed to do that. You can convert the picture data to a stream of bytes (look at typecast or flatten to string) on the sender. Use TCP/IP functions to send the data over the network.
The receiver will do the reverse (typecast back to an image, or unflatten from string) and send it to the picture indicator.
Look at the functions
I would recommend looking at the online LabVIEW tutorials
