Manage the preset conditions for ZNB network analyzer remotely

Question

I want to control the preset conditions on my ZNB using LabVIEW and the according R&S LabVIEW driver.
I could not manage to access to the path of the setup files as I always get the information that the folder "C:\Users\Public\Public Documents\Rohde-Schwarz\Vna\RecallSets" is not existing.
This happens with all the operations like reading the file catalog, generating or reading a setup file.
How do I use the driver correctly?

Answer

There are two different ways to describe the adequate path. During a Remote Desktop session you can see the following path desriptions:

- WIN Explorer:
C:\Users\Public\Public Documents\Rohde-Schwarz\Vna\RecallSets
The space in the name "Public Documents" will be split into a string and so the path name is no longer valid, when using this term in the driver

- WIN Command Prompt:
C:\Users\Public\Documents\Rohde-Schwarz\Vna\RecallSets
If you use the path from the command prompt, you can easily access to the folder

The VI in the attachment shows the correct handling of preset handling.
