用InitiateSystemShutdown(),MSDN上有个完整的例子。

The InitiateSystemShutdown function initiates a shutdown and optional restart of the specified computer.

To record a reason for the shutdown in the event log, call the InitiateSystemShutdownEx function.

BOOL InitiateSystemShutdown(
LPTSTR lpMachineName, // computer name
LPTSTR lpMessage, // message to display
DWORD dwTimeout, // length of time to display
BOOL bForceAppsClosed, // force closed option
BOOL bRebootAfterShutdown // reboot option
);
Parameters
lpMachineName
[in] Pointer to the null-terminated string that specifies the network name of the computer to shut down. If lpMachineName is NULL or an empty string, the function shuts down the local computer.
lpMessage
[in] Pointer to a null-terminated string that specifies a message to display in the shutdown dialog box. This parameter can be NULL if no message is required.
dwTimeout
[in] Specifies the time (in seconds) that the shutdown dialog box should be displayed. While this dialog box is displayed, the shutdown can be stopped by the AbortSystemShutdown function.
If dwTimeout is not zero, InitiateSystemShutdown displays a dialog box on the specified computer. The dialog box displays the name of the user who called the function, displays the message specified by the lpMessage parameter, and prompts the user to log off. The dialog box beeps when it is created and remains on top of other windows in the system. The dialog box can be moved but not closed. A timer counts down the remaining time before a forced shutdown.

If dwTimeout is zero, the computer shuts down without displaying the dialog box, and the shutdown cannot be stopped by AbortSystemShutdown.

bForceAppsClosed
[in] Specifies whether applications with unsaved changes are to be forcibly closed. If this parameter is TRUE, such applications are closed. If this parameter is FALSE, a dialog box is displayed prompting the user to close the applications.
bRebootAfterShutdown
[in] Specifies whether the computer is to restart immediately after shutting down. If this parameter is TRUE, the computer is to restart. If this parameter is FALSE, the system flushes all caches to disk, clears the screen, and displays a message indicating that it is safe to power down.
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
To shut down the local computer, the calling thread must have the SE_SHUTDOWN_NAME privilege. To shut down a remote computer, the calling thread must have the SE_REMOTE_SHUTDOWN_NAME privilege on the remote computer. By default, users can enable the SE_SHUTDOWN_NAME privilege on the computer they are logged onto, and administrators can enable the SE_REMOTE_SHUTDOWN_NAME privilege on remote computers.

Common reasons for failure include an invalid or inaccessible computer name or insufficient privilege.

For an example, see Displaying the Shutdown Dialog Box.

        VC/MFC社区版块或许是CSDN最“古老”的版块了,记忆之中,与CSDN的年龄几乎差不多。随着时间的推移,MFC技术渐渐的偏离了开发主流,若干年之后的今天,当我们面对着微软的这个经典之笔,内心充满着敬意,那些曾经的记忆,可以说代表着二十年前曾经的辉煌……
        向经典致敬,或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天,我们期待着MFC技术能够恢复其曾经的辉煌,或许这个期待会永远成为一种“梦想”,或许一切皆有可能……
        我们希望这个版块可以很好的适配Web时代,期待更好的互联网技术能够使得MFC技术框架得以重现活力,……
