Wondering where you have copied that... But WndProc is System.Windows.Forms.Control method, so how on earth would you override it in a console program with no controls in it at all? Always search MSDN library first!

WM_QUERYENDSESSION is not defined, so that needs to be defined too (it's 0x0011 by the way).
