Multiple Instruments unknown amount code reuse activex

[AV1000]

Hi

I have a question which I can't find the appropriate words to search for to solve my problem.

Basically, I have the need to develop a test rig which could have an unknown amount of units connected to it via USB, I have created an activeX control to do all the comms and this can look on the system for all the devices present.

Ideally i want to be able to create something in LabView where I can use this array/ list of devices attached and then use the same test procedure on all of them. So really what I want to do is create a VI which can take this list and then in parallel run the comms to all units.

Can anyone show me a VI that does something similar or point me in the direction of an example or tutorial on the internet, or tell me some buzz words to search for?

Thanks

Hi AV1000,

Here is some very basic example code to show you how you could implement what you want to do.

It is sequential rather than parallel, as I do not know if you ActiveX control is thread safe and so do not want to suggest a method to do that.
It also becomes a lot harder to get code to run in parallel, in your setup.
