How do I create an emergency stop custom control in LabVIEW that looks like an actual E-stop button
How can I find (or buy) a variety of custom controls for various
applications that look better than the standard NI controls.
This is very easy to do in labview.The way that you do it is by double
clicking the control. This will bring up the customize window and from
there you can make it look like you want it to by inserting pictures
into the control of the way you want it to look at each state. Look at
the shipping examples that come with labview and experiment with this
a little bit. It makes for a great GUI feature when you do this.
Hope this helps

I have two custom controls I want to create:
1. Something like a wxBitmapButton, but it acts like a checkbox. It
will look like a classic toggle switch, up for checked, down if
2. A rotary knob control. I guess it's functionally like a wxSlider
but it looks like a volume control knob.
Do either of these things exist? If not, what's the best way to go
about creating them? Would I start from a wxCheckbox and wxSlider,
then graft on the custom look? Or would it be better to go down a
level, starting with wxControl? I notice that wxBitmapButton is

I have some LabVIEW code that I would like to convert into an ActiveX
control. There was rumours that this was to be included in Version 7,
but I can't find it. Is this possible?
Currently, you cannot create ActiveX controls in LabVIEW. I agree, it
would be great to be able to embed custom LabVIEW code into other
applications via ActiveX. I will make sure that this idea is
suggested. In the meantime, if you want to embed your code into other
VIs, consider the remote panel or subpanel capabilities of LabVIEW.
These capabilities creates a shell containing the VI, much like an

My front panel needs to have two switches -- one which "Stops" the program, but allows the current processing and error-handling to complete before stopping.

I've tried modifying an existing Boolean, and then I tried creating a new custom control using a decoration and an existing switch. But I can't get seem to select the Boolean with selecting the decoration, or the decoration wants to cover-up the Boolean and I can't set the Z-order.
Any tips or advice? Can I group decorations with existing Booleans? Can I modify decorations to become Booleans? Can i create curved text?
If anyone has already created one and could share it, I'd appreciate it!

...How to easily control multiple controls in labview
How can I easily control multiple controls with a single write to in Labview? For instance, I need to update 50 different boolean indicators. When I update them one at a time I use a cntrl refrence in my event structure, but outside of an event structure how can I easily cycle through them and update without making 50 local variables if I need to do them all at once?
Why don't you use an array of boolean indicators?
Have a look at the example attached <a href="http://forums.ni.com/ni/board/message?board.id=170&view=by_date_ascending&message.id=204328#M204328" target="_blank">here</a>, which can also be applied to this. You should usually avoid updating the value of a control from more than one place, though (unless it's something like initialization, where you can guarantee not having race conditions).
Other alternatives: using an array of booleans or using the picture control to create the image.
The way i use these booleans in my UI, I had to make them separate so I could arrange them in a user friendly way. And yes this is just for initialization so they won't be getting updated in two places at once.

I have a custom control made up of a cluster that (somehow) contains invisible controls within it. These are enums that were not typedef'ed and I now need to change them. Can I access the properties of an invisible control inside a custom control so I can view them adn change them?
Create a property node for your cluster and get property "controls".
Now iterate over the array of control references and set them to visible via another property node. (see image for a simple code draft)

...How do I create Labview VISA ports for *individual* GPIB instruments using Prologix USB GPIB controller?
I'm trying to use a Prologix USB GPIB controller to control GPIB
instruments, and I would like to have a virtual serial (VISA) port for
*each instrument*, as is the case with a normal GPIB controller with a
standard NI driver. However this is not what the Prologix driver
provides -- it provides a single VISA virtual serial port for the
entire controller. To address the instrument with GPIB address 11,
you first send "++addr 11" to the serial port, and then you're talking
to instrument 11. However, this means I have to change all old
Is it possible to create a "wrapper" function of some kind that will
define a virtual serial (VISA) port for each *instrument* on the

ASRL3::11::INSTR, each time it is written to it would have to write to
the virtual serial port of the controller, say ASRL3::INSTR, first "+
+addr 11" and then the command that is sent to it.

Could some one advice me on this matter please.
I am trying to build a DLL for a set of functions created in LabVIEW. Now I am wondering if I need to use it with some other language like VB or C++, do I need to install the LabVIEW runtime of the same version as the original functions ?
Any settings required while creating the DLL ?

yes, if you want to use a dll, which is created with LabView you have to install the runtime engine.

...How do you control seperate motors with Labview through a remote control?
Forgive me if I am not typing the question correctly, or if it is a stupid question. I am only fourteen and only started learning about Labview.. I would appreciate all help possible. Thanks
What type of motors are you trying to control? How do you have them/plan to have them connected to your computer? When you say you want to control remotely, do you mean that you don't want them connected to a computer or that you want to communicate remotely through your computer (no cables)? The more information you can give the better help you will receive. Cheers
It would also be helpful to know what version of LabVIEW you are using. It's impressive that your starting to learn LabVIEW at such a young age, it will be challenging but worth it!
Well first off, thanks for asking questions to my questions, it helps me too :) The kind of motors I am trying to control are IFI Robotics Multi-Speed Motor Connect to PWM or RLY port (12 volt).. I am trying to remotely control it wirelessly, through an IFI Robotics Isaac16 EDU Robot Controller with 900MHz Short Range Radio Modem. Hope this Helps..
Oh yeah, and the version of LabView I am using is 8.5

What you will need to do in order to control it with LabVIEW is figure out what the function calls are that will be required to activate your PMW signals etc.&a...Reading controller data into LabVIEW through serial connections to controllers?
I'd like to read data from environmental chamber controllers (System Plus) into LabVIEW through RS232 connections. Has anyone done something similar? I see interfacing with the serial controllers as the biggest obstacle and although not directly related to LabVIEW programming, I'm hoping someone here can give me some advice or resources on how best to do so now days. My first thought is to write a program with VB or C++ to act as a terminal and write the data to a text file for LabVIEW to poll. Aside from using Telix decades ago to work with BBSes, my only other serial experience consists of interfacing with a Kiethly multimeter using a C++ program. I would rather not use multiple PCs but I have never worked with more than one serial port on a computer before in the past. Perhaps LabVIEW itself already provides for multiple serial card communications (wouldn't that be perfect)? Any info would be great. Regards, Dave
LabVIEW has had support for serial communication for as long as I've used it and may have been part of version 1. It also supports multiple serial ports - built-in and USB->RS232. There are even a couple of shipping examples. I've not used this particular chamber but I've used several with serial connections.
