WlxDisplayLockedNotice function (winwlx.h)

[The WlxDisplayLockedNotice function is no longer available for use as of Windows Server 2008 and Windows Vista.]

Allows the GINA to display information about the lock, such as who locked the workstation and when it was locked.

The WlxDisplayLockedNotice function must be implemented by a replacement GINA DLL. Winlogon calls this function when the workstation is placed in the locked state.

Note   GINA DLLs are ignored in Windows Vista.


void WlxDisplayLockedNotice(
  PVOID pWlxContext



Pointer to the GINA context associated with this window station. This is the context value that the GINA returns when Winlogon calls WlxInitialize for this station.

Return value



To display lock information, the GINA must display a dialog box that will be interrupted by a WLX_WM_SAS message. For more information, see Sending Messages to the GINA.

Before calling WlxDisplayLockedNotice, Winlogon sets the desktop state so that the current desktop is the Winlogon desktop and sets the workstation state so that the desktop is locked.
