Sorry, I misread what you said before.

I have never seen that property before.  I'll have to look at that, it might
help me with some issues in my own projects ;-)

That will not prevent a window from being closed at all.  A user can still
use ALT-F4 to close an active window even when it does not have a X button
or a system menu.  Since you are deriving a new class, you can override the
CloseQuery() method, or override the WndProc() method to intercept the
WM_SYSCOMMAND or WM_CLOSE message.
