Subject: RE: [GD-Windows] Detecting locked screen

> You can check if it has happened:

Thanks, that helps, but it doesn't quite solve it.  SwitchDesktop() will
still fail if the screen saver has turned on but the actual lock hasn't
occurred.

There is a very brief interval (under a couple seconds) when the screen
saver kicks in and it WON'T lock the desktop, and
SwitchDesktop() will fail then even if the desktop hasn't actually been
locked (i.e. you can tap a key or move the mouse and the screensaver
turns off and there's no logon box).

Basically I'm looking for a fictitious API that is like:

if ( WorkstationLocked() )
....

Failing that, being able to process a LockWorkstation() or whatever
would do the trick as well.

Thanks,

Brian
