Use WTSQuerySessionInformation() with the WTSInfoClass parameter set to
WTSUserName.

You don't, not via HandlerEx() anyway.  That capability was added in XP.
You will just have to use a separate window that intercepts the
WM_QUERYENDSESSION and WM_ENDSESSION messages to see when the user is
logging out. But you can't detect when the user is logging in that way.  You
would probably have to write a replacement GINA.DLL to hook into the
WinLogon screen itself.

Otherwise, the simpliest way to detect login and logout is to simply run a
loop that repeadedly gets the username of the currently active user, and
then check when that value changes.
