.net - Detect laptop lid closure and opening -


Is it possible to find out when the laptop lid open or closed? It is not possible to read what I have read, but before that I have got help with impossible.

Whatever I've found can be in the right direction is one. Is OS possible to call them "sniff"?

I am VB I am using Net, but will take suggestions in any language. Thank you for your time and advice. In

Edit : My software will eventually override the actions (based on user preference), when stops the lid, then listen to suspend and other actions which generally Forms when the lid closes is not an option.

full working C # code for WPF application that shows how the lid to open / close To hear the events:
