Think 32 bit vs 64 bit. .net will always use the correct architecture. Custom library that has been developed externally, can create a security breach as well.... .dll .ocx.... Native .net that you code yourself would be must trustworthy. But be aware that you need to make sure that the .net version used will always be compatible with the latest .net updates... sometimes it creates issues. this is likely less possible with external code if they are not relying on interpreter (java .net C++ or python.) Another case would be licensing. When you use someone else code, be sure the licensing allow you to use it in your situation.

A wrapper will give him the same situation and create another unnecessary layer. Did you know that a Cluster is what you are looking for? in your case, it will be two cluster into another one. You can create your own header file (.h) and import your .dll into LabVIEW. That would be much better solution Note that the UINT is a separate parameter.

Of course it is possible. National vision library will be helpful in this case. if you do not want to pay extra$$$ per station deployed, you can use OpenCV and create your own wrapper.

Try it by yourself. it's depend of your adapter. This VI use the friendly name that is usually a copy of what is seen in the DEVICE MANAGER.

Indeed, if you never connect the cable, it will crash. I have now move away from ftdi. I found a much better solution. Microchip MCP2221A Also a version for SPI is available. Amazing IC with a lot more capability for a fraction of the price. We develop our own PCB to interface it and it still become cheaper that the cable from FTDI.

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. Benoit

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.

View File .xml test report Measurements.zip This XML test report library is available for you to modify at your will. It is based on the IPC-2547 standard so it is easier for any other application or database to parse. The html file report offered by LabVIEW was not sufficient for my need. So I created those. enjoy!!! Submitter Benoit Submitted 02/26/2018 Category *Uncertified* LabVIEW Version

View File 55 easily distinguishable color.vi This is the only way I found how to have a bunch of color that are unique and easily distinguishable. The maximum I saw in the web was about 26. This one offer 55 of them without gray tone. You can modify this VI to support gray tone as well and goes up to 60 colors. Please use the new version at: New version Submitter Benoit Submitted 02/08/2018 Category *Uncertified* LabVIEW Version

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. Benoit

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 Benoit

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. Benoit

robijn 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.
