Titolo: [API] ExitWindowsEx

Ciao a tutto l' ng,
Vorrei, solo sapere, come utilizzare la funzione ExitWindowsEx, più
precisamente, vorrei sapere a cosa corrispondono i parametri che le devo
trasmettere. Inoltre,
in fase di debug, VB, mi dà un messaggio di errore che chiede l'assegnazione
della funzione a qualcosa (presumo ad una variabile)ma....non capisco a
quale variabile (magari ad una di sistema)!!!??
Ringrazio, fin d'ora, chiunque vorrà rispondermi .
Ciao .

da win32:
The ExitWindowsEx function either logs off, shuts down, or shuts down
and restarts the system. 
BOOL ExitWindowsEx(
    UINT uFlags,	// shutdown operation
    DWORD dwReserved 	// reserved
   );	
 
Parameters
uFlags
Specifies the type of shutdown. This parameter must be some combination
of the following values: 
Value	Meaning
EWX_FORCE	Forces processes to terminate. When this flag is set, Windows
does not send the messages WM_QUERYENDSESSION and WM_ENDSESSION to the
applications currently running in the system. This can cause the
applications to lose data. Therefore, you should only use this flag in
an emergency.
EWX_LOGOFF	Shuts down all processes running in the security context of
the process that called the ExitWindowsEx function. Then it logs the
user off.
EWX_POWEROFF	Shuts down the system and turns off the power. The system
must support the power-off feature.Windows NT: The calling process must
have the SE_SHUTDOWN_NAME privilege. For more information, see the
following Remarks section. Windows 95: Security privileges are not
supported or required.
EWX_REBOOT	Shuts down the system and then restarts the system. Windows
NT: The calling process must have the SE_SHUTDOWN_NAME privilege. For
more information, see the following Remarks section. Windows 95:
Security privileges are not supported or required.
EWX_SHUTDOWN	Shuts down the system to a point at which it is safe to
turn off the power. All file buffers have been flushed to disk, and all
running processes have stopped. Windows NT: The calling process must
have the SE_SHUTDOWN_NAME privilege. For more information, see the
following Remarks section. Windows 95: Security privileges are not
supported or required.
 
dwReserved
Reserved; this parameter is ignored. 
 
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError. 
Remarks
The ExitWindowsEx function returns as soon as it has initiated the
shutdown. The shutdown or logoff then proceeds asynchronously. 
During a shutdown or log-off operation, applications that are shut down
are allowed a specific amount of time to respond to the shutdown
request. If the time expires, Windows displays a dialog box that allows
the user to forcibly shut down the application, to retry the shutdown,
or to cancel the shutdown request. If the EWX_FORCE value is specified,
Windows always forces applications to close and does not display the
dialog box. 
The ExitWindowsEx function sends a separate notification message,
CTRL_SHUTDOWN_EVENT or CTRL_LOGOFF_EVENT as the situation warrants, to
console processes. A console process routes these messages to its
HandlerRoutine functions, which are added and removed by calls to the
SetConsoleCtrlHandler function. ExitWindowsEx sends these notification
messages asynchronously; thus, an application cannot assume that the
console notification messages have been handled when a call to
ExitWindowsEx returns. 
Windows NT: To shut down or restart the system, the calling process must
use the AdjustTokenPrivileges function to enable the SE_SHUTDOWN_NAME
privilege. For more information about security privileges, see
Privileges. 
Windows 95: Security privileges are not supported or required.
