Be sure as well to never use hub. I have many issues with USB hub.

If you want to get the list of USB device connected, you can use this VI. note that if your web cam do now have embedded serial number, the device path is reported according to the USB port connected. if you connect the same model of webcam at the same port, Windows will use the same friendly name.

I use Spinnel USB cam 2M. they do have a embedded serial number programmed upon request... 50$ per unit. quite decent for this usb camera with a low distortion lenses.

USB Scanner.vi

I use both Ni and Lava org when it is related to NI design or limitation. Because NI will recognize only their forum for support.

OK I just found a way...

Using wild card "*vi name or library name*"

Here is what I did:

Since I have over 2000 VI on that project with over 60 different library

Since many library has some VI that need to be accessible by VI-Server for external application

I have created a sub library named: "Publish_VI.lvlib" in every library that need to publish one or more vi.

In the list ov VI to publish by VI Server I have only one entry to put for any VI to be published: +*Publish_VI.lvlib*

Done

This way if I need to add any other VI, i just need to add it to the sub library of any object "Publish_VI.lvlib" and it is automatically available without any further configuration.

Sometimes problem create opportunity to improve the overall system.

Hello all,

Is there any of you ever be able to push more than 30 VI in the exported VI list of VI server?

I think I found a bug that is there since at least LabVIEW 2011.

WAIT... don't answer the easy one... "export all VI"... if you were about to answer that, that means you are not developing a safe application.

Thanks for any help.

hi everyone, know it's an old post, but I realy need to do that in order to save time to my team.

here is what I want to do:

at LabVIEW lunch, running a vi that will configure some VI property in the LabVIEW pallet tools.

Per example changing text in a label using VI script.

My VI is working, but I wan LabVIEW to run it automatically on a LabVIEW start.

Thanks

Sorry for the late reply.

I didn't try to benchmark this library. so performance point of view, I have no idea.

Sorry for the late reply.

You have to connect at least once your FTDI device and having the driver installed in windows. Then this problem should never happen again.

I have a quite complex project that requires me to have multiple executable running.

My problem is as follow:

MAIN.exe need to load in a sub panel any of the OTHER.exe.

All the exe has been compiled in LabVIEW. The MAIN.exe come from a different project than the OTHER.exe.

In LabVIEW everything is working.

I can access successfully the control and indicator value of the OTHER.exe trough vi server.

Using the same VI reference, should work in the sub panel. But why it is not working?

Thanks

Hello

It can give a good geek look. lol but is it possible to have it in labview version 2011? i'm a geek. lol

Thanks

Hi there,

The only way I found out is to set the value of the index and then the key focus. The problem that remain is that the first element show is the index value... For a GUI that you fix the size of the array, it could be confusing for the user.

Benoit

Wenn two simple way to do it.

if it's in string, just split the string character by character

if it's a number, using the Quotient & Remainder just divide it by 1000 and keep the out put floor(x/y) then from the original value remove this reminder multily by 1000... and execute again with 100, 10 and keep the last.

Where is your VI?

if you didn't used IMAQ, I'll love to take a look at your VI.

Thanks

Benoit

Well in this case, no Linux is not an option. I'll not bother like that if it was.

Thanks

Benoit

Where is the ActiveX?

I'm looking since 3 days in a row full time to find a free solution that works only to grab a picture from web cam.

I can't pay for IMAQ...

Is anyone has a real VI that works with or without dll activeX what ever the solution that do not use the IMAQ?

Thanks

I know it's quite old, but I'm trying to get image from the web cam from your VI readAForge-sample.vi.

When I open it, it's a broken VI.

Is it possible to have any help on this?

Thanks

In my point of view, The fact that Ni sell a home version might help a little bit. But this version will bring a lot's of new questions. If Lavag.org can reach this market, We might have a lot more people visit this website. Personally, i love it and the answer given by people here is more relevant than what is found on NI.com. 3 hours of reasearch on Ni.com to find a simple answer is not a good solution for me. Here the question are quickly answered and no insult are sent to no one. Lavag.org is a family... if we found the family to small, we just need to reach a new market and do some advertisement for it.

I'm happy that what we were able to find trough google, the link are not broken.

Overal, I like it, but in some pages my eyes got lost. Not used to the interface yet.

I'm not a big fan of the square stuff... the menu looks like Windows10.... I do not like this look. but it's only matter of taste.

Benoit

Think about using the sequence localy, but having a request to the server to validate if the local version is good. per example MD5 is a very good way to check if the local file is ok. The MD5 is saved on the server as well. By doing this, you reduce the data between the server and the client. It looks over kill, but it's a very efficient way to reduce the data that is sent to the server and then the server perform much faster. less data goes trough IT switch and the best advantage, in a case of lost link, you can decide to run with the local version. It's reduce the down time.

OK I found a super easy way... drop the VI in a text constant and magically the good VI name with the library included will appear. use this constant as VI name for the VI server. this can be done for the type specifier as well.

Candidus, your example is good. it's represent exactly what I did.

That solved my issue.

Thanks everyones for your help.

Benoit

OK I tried your project. It works fine till I include the remote method in a library. How can I refer to this VI if it's included in a library??? it's ssems that it's not working anymore.

Thanks for any help.

There it is... finaly... 

Because the code given in the FTDI web page is not convenient, not working and haven't been developed by real LABview programmer, I decided to create a library for the I2C.

a version for SPI will come soon.

This library is free to use. If FTDI want's it in ther site, I do not allow you to publish it since you didn't help any of your customer with LABview.

but of course feel free to publish this link.
