How to make an activex in Labview!

I don't know how to make an activex in Labview5.0.How can I do ,can you tell me the specified steps?please!
Thanks a lot!

If you want to embed an ActiveX object on the front panel, you go to the ActiveX palette and drop a container there. You select the object by right clicking on it and choosing "Insert ActiveX Object". You then browse for the object you want. In your diagram, you use property node and invoke node functions found on the Communication>ActiveX palette. You can also use the Automation Open function and in that case, you just use an automation RefNum. There are examples (at least LabVIEW 5.1 has them) - Help>Search Examples>Communication>ActiveX.
If, on the other hand, if you're asking how to make an ActiveX object out of a LabVIEW VI, that's not possible.

How to make editable Table in LabVIEW

Hi,
Could you please let me know how can I make an editable table. I read all the contents of the table from a spreadsheet file but I would like when I click on any of the entries in the first column I get checkboxs for all the entries in that row and after updating them the table should also automatically be updated with new values
For example
Let's say this is my table
Device Name Bit 0 Bit 1 Bit 2 Bit 3 Value in binary
1 1.bit0 1.bit1 1.bit2 1.bit3 0000
2 2.bit0 2.bit1 2.bit2 2.bit3 0000
3 3.bit0 3.bit1 3.bit2 3.bit3 0000
4 4.bit0 4.bit1 4.bit2 4.bit3 0000
Now if the user click on 1, I should see 4 check boxes for 1bit0 1.bit1 1.bit2 1.bit3 and as soon as the user update any of them the binary value should be updates . For example if the user enable 1.bit1 and 1.bit 3 then the binary value should become 0101
Could you please let me know if I can I use Table control to do this and how can I do it in LabVIEW
Thanks

Why does the user even need to select a row first? Wouldnt it be sufficient to have an array of clusters, where each cluster contains a devicename string, four enums with 0,1, and a string for the value (or binary formatted numeric). Elements that don't accept inputs should be disabled, but not greyed and can be recalculated whenever needed.
The main problem is the cosmetic fact that this will no longer resemble a table because of all the extra borders...
... That's why we have this idea! Go vote for it!! Thanks!
Here's what I had in mind (LabVIEW 8.2). All you need to add is parsing your input file into the cluster structure. If the number of clusters is large, show the vertical scrollbar of the array.
(...note that it would look much better with my above mentioned idea implemeneted! )

How to make executable file in labview.

HI All,

You need the Professional version to make an executable. You could also buy the App Builder seperately. I don't remember the price at the top of my head.

How to make a video in Labview that sync with scenario data?

Hi guys,
I am doing a program that shows the scenario data of a satellite at different positions. (For eg, at the position nearer to sun, the temperature data is higher.....)
To make the front panel more interesting, I am thinking to add in a video of a satellite orbiting the Earth. The video has to sync with the data I am showing.
The orbital time of my satellite is 90 minutes = 5400 seconds. If I am going to use the picture ring control method, I have to import 5820 frames of pictures into the picture ring control. My understanding is that each time the user can only import one image (correct me if I am wrong). That would mean I have to import the pictures for 5400 times.
Is there any other way to do this? I do not want to waste my time on importing so many images.
Vanessa
Solved!
Go to Solution.

Okay there are many ways to do this, and I'm not certain which would be less work.
One option would be to have a picture ring, with 5820 individual images that you then pick which one to display as an index. If you were to do this I'd recommend some LabVIEW scripting to create the control, importing the images programatically. I think memory wise storing these images in this control would be very difficult for LabVIEW, but it could be done.
What I think would be a better option, is to use a single 2D Picture control, and then load a new image from disk (where I hope these images are stored). You then just load the right image for the right time. Look under the Graphics and Sound >> Graphics Format to see how to open a file from disk. This path will change for each image.
EDIT: Here is an old link that is still relavent http://digital.ni.com/public.nsf/allkb/328AF568F15B36328625696200511EF0
DOUBLE EDIT: Really? Scripting doesn't allow importing pictures? Well there is likely a work around but that sucks go vote for it here.

Re: how to make bode plots in Labview 7.1 without using Control Toolbox

I am using Labview 10. I have connected a signal generator, a LP RC filter and an oscilloscope. I am using Labview in order to control the generator (sine with frequency sweep) and acquire the signal from the scope. I want to plot the Bode diagram without using the transfer function, from the amplitude of the sine signal and the frequency.
Thank you very much.
Best Regards.

Hi pflo,
Are you using the CD Bode Plot VI or the SI Bode Plot VI? For the CD plot you must use a transfer function. Below, please find a link to an example on how to create a Bode plot without using the toolkit.

How to make bode plots in Labview 7.1 without using Control Toolbox

I'm trying to make a bode plots from transfer function using Labview 7.1. My installed labview not contains any toolbox, so I have to create the block diagram of bode plots my self. I have a problem when creating the phase bode plots for polinomial with conjugate roots pairs. Suppose the polinomial is ax^2+bx+c, with a,b,c is the polinomial coefficients. If b coefficients is negatif, i have no problem, because the phase is start at 0, and the final value is 180. But if the b coefficient is positive, the phase plots starts at -180 and it's final value is 0. So, if there is any one who can helps me to give any solution, i'll really appreciate that. Or if there is any of you who had made the program to create the bode plots from a transfer function, i hope you can share the code with me. Thank you.

Hey pflo,
Are you using LabVIEW 7.1? Can you explain the problem that you are having with the using the Bode Plot VI? Below please find links to some documentation on the Control Design Toolkit. With further information on your problem I will be able to better assist you with the toolkit.

How to make Bitwise operation in Labview ?

Hello.. everyone,
I need to make the bitwise operation (or) in Labview, but I can't find it somewhere!!!
Anybody has the experiece about it, pls help me !!
Thanks a lot

Hi Nok,
The standard OR function in the boolean sub palette of the functions palette performs a bitwise operation on it's input data. This is a polymorphic function so you can input scalar booleans, arrays of booleans or numerics.
Hope this helps,

How to make a movie in LabView Real-Time

I know that the IMAQ AVI routines do not work under LabVIEW RT (which sucks BTW), but I really need to make some sort of movie file from the images that I get from a PXI-1411 card under LabView RT. I want to make a time lapse movie, so I would take a frame every 5 minutes or so, and then append it to an AVI or .MOV or other file. Is there a third party tool that could do this or some other way to do this under LabView RT? I really don't care what the format of the file is just so that it can be displayed on a web browser.

Hi Kirk -
I believe the method discussed in this post is the most reasonable: http://forums.ni.com/ni/board/message?board.id=200&message.id=10160#M10160
I don't know of any 3rd-party tools for creating movie files in LVRT. The AVI functions can't be supported in LVRT because they're based on DirectShow functionalities, which are only available in Windows environments.

How to make labview real time understand sequence context

Does anyone know how to make Labview RT to understand teststand sequence context? My sequence context is defined as "TS.SequenceContext" as the screenshot in the attachment.
If we need to point a VI for this Sequence Context then which VI from teststand to use? and do we need to add this VI to the Labview Projectr Explorer in RT System to build the project?
I'm using Labview 2009 and teststand 4.2.1.
Thank you very much

LabVIEW RT does not support ActiveX which is required for TestStand.

How to make a RESET button in labview ?

how to make a RESET button in labview which resets all the elements in an array back to inactive element. Rather than deleting values in every column of array its better to create a RESET button ... how to make it ???

You seem to have some misconceptions.
Is the array a control or an indicator or just some data held in a shift register or feedback node?
What you are probably looking for is an empty array. An empty array has a size of zero and has no elements (active or inactive). From your mentioning of "rows", you seem to have a 2D array.
The size of the array is independent of the visible size of the container.
Clearing an array means simply writing an empty array of the same datatype to it's terminal (or internal data structure). If the array is a control, you need to write to a local variable of it instead.
Can you show us some code so we can have a better understanding what exactly you mean by "array" in this context? Thanks!

How to make a LabVIEW application into a screensaver?

How can I turn my Labview application into a screensaver. I read an old email from Jean-Pierre Drolet from 2001, where he writes that you only need to make a application of your .VI and then change the extension from .exe to .scr, rightclick and 'install'.
When I did that I got some error msg. in the 'display properties' 'screensaver' ... %1 requires %2 ... (cant see all). Does anyone know the answer how to make it correct?
(if you want a more difficult task.....)
To make it a complete screensaver the program should should act differently according to commandline switches:
/s : enter screen saver mode
/c : enter config mode
/p : enter preview mode
How to make it?
I would be happy if someone could ans
wer my first question(that easy part).By the way im running Laview 6.1 on a win 2000 comp.

Just made a simple VI with no menu or title bar, set the window size to always fill the screen and built it as application.scr. Installed it...everything OK. However if the RTE is located in the same directory as the application launching it returned an error saying the application could not find the neccesary resources...that might be what you see as well...(?).
On a machine with LV installed the RTE is already available so that is not a problem...Making it respond to commandline switches can be done either using the new commandline functionality of LV7 or using the commandline dll you can find here on the zone...it allows the application to capture and act on the commandlines when the application is launched.
Now you may want to add code in your application t
hat reacts to mouse actions so that the application terminates when the user moves the mouse /clicks a key etc...like other screensavers do. Use an event structure to capture such events...
Here's a general description on how to create screensavers that also applies in this case (nothing new there..but just to show that the procedure you already have is as MS says...):
