Hi,

 

I want to know how to enable/ disable the VISA option "Show all devices accessible to VISA" (Measurement & Automation >> Tools » NI-VISA » VISA Options under PXI/PCI and WireFire Interfaces) with C#

 

this is to see all PXI resourses without the end-user configures nothing

 

i saw this post

Hi Geck0;

 

I found that the "Show all devices accessible to VISA" can be changed via the visaconfig.ini file changing the section:

 

[VISA-CONFIG]
ShowRegisteredDevOnly = 0

 

Here is a link to a document in which this is explained a little more, although I couldn't find the file on the specified path (in fact I found two visaconfig.ini that could be the ones that needed to be changed) inside:

 

C:\Program Files\IVI Foundation\VISA\WinNT\NIvisa

C:\ProgramData\National Instruments\NIvisa

 

I hope the information is useful.

 

Good Luck
