如果是关机： Public Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, ByVal dwReserved As Long) As LongParameters uFlags [in] Specifies the type of shutdown. This parameter must include one of the following values. Value Meaning 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/2000: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Res section.
EWX_REBOOT Shuts down the system and then restarts the system. Windows NT/2000: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Res section.
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/2000: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Res section.
This parameter can optionally include the following values. Value Meaning EWX_FORCE Forces processes to terminate. When this flag is set, the system does not send the WM_QUERYENDSESSION and WM_ENDSESSION messages. This can cause the applications to lose data. Therefore, you should only use this flag in an emergency. EWX_FORCEIFHUNG Windows 2000: Forces processes to terminate if they do not respond to the WM_QUERYENDSESSION or WM_ENDSESSION message. This flag is ignored if EWX_FORCE is used.

其實道理差不多,重點在三個方面
其一,了解 WM_POWER;WM_POWERBROADCAST等
這類消息(可查相關資料[P1063.visual basic 5.0 win32 api 開發人員指南 美.dan appleman著])
其二,注意系統挂起時各窗口狀態及信息的設置
其三,喚醒時狀態的恢復其時,我也只是業余時思考一下,并未著手去作這個程式,
因考慮可能麻煩很多,亦并不是很實用我曾經有一個想法是,在WIN9X的機器當操作人离開時,通過一個熱鍵
將電腦挂起,喚醒時需輸入密碼,起到保護和省電作用,但限制電腦挂起則
容易多了,如上,你說是嗎~ 
