Hello,

Thought you write code and run it and oppos the computer is shut down, ha !
So its happened to me and I tried to figure out why, what cause to that bug - a critical one, so Here the code who can shut down the computer you on it, Remember, I have no warranty to the code and its conclusions.

So,

Open a modal dialog and write this code, i.e. when the dialog closing event occurred

Win32.SetForegroundWindow(this.Owner.Handle);

this.ShowInTaskbar = false;

(must be in the same order).

Enjoy or not.
