求助，求一个检测鼠标键盘无操作自动关机的脚本

[昵称全被占用了]

首先谢谢您的帮助，想用VB脚本实现，再指定时间内检测到鼠标键盘无操作执行关机命令，并出现对话框提示10分钟后关机，在出现对话框期间检测到键盘鼠标有操作，结束关机命令并重新检测，谢谢，谢谢，谢谢，真心不想用软件华而不实

VBA脚本不太清楚,不过在VB6中可以使用键盘鼠标HOOK,外加调用关机函数. 键盘鼠标HOOK代码封装: http://www.m5home.com/bak_blog/article/245.html 关机函数封装: http://www.m5home.com/bbs/thread-391-1-1.html 思路为: 窗体加一个定时器,周期设置为1秒,然后定时器事件里将一个全局变量A加1,这个A就是空闲时间了. 当这个时间大于某个设定的值,就可以调用关机了. 键盘鼠标HOOK中每产生键盘或鼠标事件,则就将A置0. 定时器内代码类似这样:

dim TimeLeft as long

private sub timer1_timer()
    timeleft=timeleft+1
    if timeleft>600 then     '600秒就是10分钟
        timer1.enabled=false:doevents
        call ShutDownPC(1)       '调用关机
    end if
end sub

然后鼠标键盘事件中只需要timeleft=0就行了.

How To Create a Screen Saver in Visual Basic Last reviewed: September 13, 1996 Article ID: Q146907 The information in this article applies to: - Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 16-bit, for Windows, version 4.0 SUMMARY You can create a Windows screen saver with Visual Basic by following the guidelines listed below. However, please note that this article gives only a very rough outline of what you should do for a robust screen saver. These are general guidelines only. MORE INFORMATION Follow these guidelines when creating a Windows screen saver with Visual Basic: In the File Make EXE File dialog, insert the string SCRNSAVE: (in upper case) at the beginning of the Application Title. For example: SCRNSAVE:Flying Fish. In the File Make EXE File dialog, specify the program file name extension as .SCR instead of .EXE. Locate the .SCR program file in the \WINDOWS directory. Give your form the following property settings so that it occupies the entire screen and does not have a title bar: Caption = "" (no caption) ControlBox = False MaxButton = False MinButton = False WindowState = 2 (maximized) Add code to all MouseMove, MouseDown, and KeyDown event handlers that exit the program. Because Visual Basic may invoke the MouseMove event when the form is first loaded, you must write code to ignore the first MouseMove event. The following MouseMove code avoids an artifact event that occurs when the application is first activated or when the application is running and another instance starts (causing loss of focus) and then quits (restoring focus): Private Sub Form_MouseMove (Button As Integer, Shift As Integer, _ X As Single, Y As Single) Static count As Integer If count > 2 Then End Else count = count + 1 End If End Sub This gives you a bit of slack when it comes to artifact MouseMove events. You will want to do something similar with the MouseDown and KeyDown events. Preventing Multiple Launches Windows usually launches the screen saver program multiple times. To prevent more than one copy of your screen saver from running, add the following statements to the Form_Load event handler, or Sub Main if used: Private Sub Form_Load () If App.PrevInstance Then End End If End Sub There is no reason to attempt to restore the previous instance of the screen saver as the active window because it will become the active window when the new instance ends. All you have to do is terminate when you see another instance running. To prevent multiple instances of the application from running as well as to keep the application running, you should move the code from the Form_Load() to a Sub Main(). Then set the project's Startup Form Option to Sub Main(). Setting the project to begin processing at Sub Main is done on the Project tab which is part of Options... under Tools menu. For example: Public Sub Main () If App.PrevInstance Then ' If already running, end the application. End Else Form1.Show 1 ' Show the screen saver form. End If End Sub Launching the Screen Saver Windows takes care of launching the Screen Saver. It keeps track of system idle time and launches the screen saver program. You can use a timer control to periodically draw graphics on the form. Screen savers are selected and configured from Windows Control Panel in the Desktop dialog. The screen saver section of this dialog has a button labeled Setup that invokes the screen saver program with the command line option /c. When your program is invoked with this option, you can display a configuration form to allow the user to select settings such as speed, number of objects, colors, and so on. Detect the /c command line parameter by checking the Command$ function. For example: Private Sub Form_Load () If Command$ = "/c" Then frmConfig.Show ' Display configuration form. Unload Me ' Bypass regular form. End If End Sub When Windows launches the screen saver, it usually specifies the command line option /s. Possible Improvements You may also want your program to appear on top of all other windows by making it a TOPMOST window. For additional information, please see the following article(s) in the Microsoft Knowledge Base: ARTICLE-ID: Q84251 TITLE : How to Create a Topmost or Floating Window in Visual Basic Also, you can find two example programs and a complete explanation showing how to write your own screen savers in Visual Basic in the following book: "Visual Basic Workshop 3.0" by John C. Craig, published by Microsoft Press. This article is a rough outline of what you should do for a robust screen saver. For example, you might want to have the startup be a Sub Main() in which you check for a previous instance and End if there is one. This would avoid the form load totally if there were already an instance running. It might also avoid the artifact MouseMove problem. -------------------------------------------------------------------------------- Additional reference words: 4.00 vb4win vb416 KBCategory: kbprg kbcode KBSubcategory: APrgOther THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
