VISA Resource name Select

[jyang72211]

Hi all,

I have a visa resource name select in my program that would allow me to select my GPIB channel.  When I click on the down arrow to select, it takes a long time (about 6s) for the options to show up.  Yes, some of the options are remote resources.  Is there a way to make the visa resource name select drop down box more responsive?  Thanks!

I dunno - speed up the network?  If the resources you are interested in never change, maybe you can hardcode some constants and select from them instead?

Maybe there are some setting in MAX that I can modify?

The list can only populate as quickly as it can locate all of the resources, so as billko said, your bottleneck here is your network speed.

Well, probably not the speed of the network itself, but how quickly the resources respond to pings or whatever protocol is used to check their availability.

It is not anything in MAX that is slowing you down, it is how quickly the network resources are being located.

Use visa find resources at the start of your program. That should work.

Edit: I said should work - let me know if it in fact does work!

Technically it doesn't speed things up, but moves the delay somewhere not so annoying.  It's a good compromise!

If you place a Open Visa connection and Create Control it'll automatically scan, yes. You'll see the ones found/visible in MAX.
