Define what you mean about "project". The Front Panel of your main VI? Or something else?

my front panel...vi

Hi Asif,

use an event structure with a TimeOut event set to your "some interval".

When the TimeOut event is fired you can maximize any window you like to.

Btw. I would be very annoyed when user interfaces change window sizes by their own…

how it will check that no one is working on PC?

Thanks

Hi Asif,

the TimeOut is fired when no other event is present.

"No one is working" means "no user input events"…

I believe this is not this simple. If you only use that LabVIEW Event structure you can capture events belonging to this LabVIEW application. Lets imagine the LV app is minimized in the system taskbar. If a user working with any other Windows program or software, you will not get this info in the LV app. 

So we need to register somehow for a mouse movement event globally, so the LabVIEW app would capture ANY mouse event globally in the OS... Or something like that. I have to search, I have no idea how to do it.

Another option to try to use a .NET callback, and capture when the screen saver goes on. Then you just set the required timeout for the screensaver, capture this event from LabVIEW, and maximize front panel when needed...

Hi,

there are those InputDevice functions you could use to monitor mouse/keyboard inputs…

Yes, but then you need polling. Event registered would be more elegant 🙂

Edit: polling option, OP should modify this code as required:
