Repaint window when no users are logged in

Is it possible to repaint a window when there are no active users logged on to a windows machine using c sharp? And will that window be available to scr开发者_JAVA技巧een capture program? Or is it not possible at all and a user must be logged into the machine.

I make use of the below:

SetForegroundWindow(handle);

InvalidateRect(IntPtr.Zero, IntPtr.Zero, true);

UpdateWindow(handle);

Thanks all for any help

Since there is no user logged in, there is no UI running.

So, no, you can't repaint under such circumstances (there is no window to repaint).

Yes it is, the logon screen is a special desktop (Windows can have several desktops). A smilar question (but not identical): WPF Window on Winlogon Desktop
