Hi,  
I'd like to know if it is possible to check (by script) if a specific Window is open in a specific Project on another remote computer (on the same network) running Vision Client?  
Can we get the info from the Gateway?

I couldn't find a ready built-in solution, but there's a few ways to approach it.

If it's always the same window, the same project and the same client, you might just have a window open/close event script on the target project, that checks the hostname (from the [system client tags](https://docs.inductiveautomation.com/display/DOC81/System+Tags#SystemTags-SystemClientTags(VisionOnly))) and sets the value of a memory tag to match the window status.

Otherwise, I would try something similar to [this post](https://forum.inductiveautomation.com/t/access-a-window-reference-from-gateway-script/24359/3) and achieve it using messages.

Please see [system.util.sendMessage()](https://docs.inductiveautomation.com/display/DOC81/system.util.sendMessage) for more details, but the gist of it is you can set `hostName` to send the message only to the specific computer you want and `project` to the specific project you want, while specifying the window name in the `payload`.

Then, in that project, the message handler can check if the specified window is open and send a message back with the result.

You'd need a message handler in your original project that would process the result and do whatever you want with it.

I'm trying to think of a way to make it more automatic, maybe by having the gateway handle a request.

Got it working using your first solution with just a small adjustment as just using the Memory Tag and the visionWindowClosed event on the Vision Window

Works great! Thanks.
