Hi,
Maybe silly question, but will really help me a lot
I have one web app, that user will click a button to submit some info.
And I hope to know the client PC local environment variables like logon name, domain name, computer name etc.
So no need user type in again, also avoid typo.
But I could only get them from Web App Server itself, not from user's remote PC hosting web browser.
Any hint?

.. maybe?
You can link in Javascript to App Designer, and Javascript can access environment variables

However, there are a bunch of limitations on what you can do from Javascript in App Designer; https://www.mathworks.com/matlabcentral/answers/1845323-add-a-javascript-widget-to-an-app-designer-app#answer_1093218
It looks to me as if the limitations would make it impractical to do what you are hoping to do.
