　　 1.定时。可以用VB中的Timer控件结合计算机的系统时间来进行精确的定时。
　　 2.关闭计算机。这可以调用Win32 API函数 ExitWindowsEx 来关闭计算机。---

　下面首先来说明一下 ExitWindowsEx 函数，该函数在VB中的声明如下：

Declare Function ExitWindowsEx Lib "user32" Alias "ExitWindowsEx" _
　 (ByVal uFlags As Long, ByVal dwReserved As Long) As Long

【返回值】
　　　 Long，非零表示成功，零表示失败。
【参数表】
　　　 uFlags --------- Long，
　指定下述一个或多个标志（用OR运算符合并到一起）
　　　 EWX_FORCE=4
　强迫中止没有响应的进程
　　　 EWX_LOGOFF=0
　中止进程，然后注销
　　　 EWX_SHUTDOWN=1
　关掉系统电源（如果可能的话，ATX电源就可以）
　　　 EWX_REBOOT=2 重新引导系统
　　　 dwReserved ----- Long，保留，设为零
　好了，现在可以开始编程了。

　 1. 新建一个标准EXE工程。
　 2. 在窗体上放置一个TextBox控件，用以输入定时时间。
　 3. 在TextBox控件之下放置两个OptionButton控件，组成控件数组，用以选择定时模式。
　 4. 在OptionButton控件之下放置一个CommandButton.
　 5. 随便在窗体的某地方放置一Timer控件。

　以上控件了需要设置的属性值如下：

对象属性设置
Text1 Text 空
Option1(0) Caption 在指定时间关机
(时间格式：00:00:00)
Index 0
Option1(1) Caption 延迟指定的时间关机
Index 0
Command1 Caption 确定
Timer1 Interval 15000（精确到1/4分钟，如要更精确可减少该值）
Enabled False

　增加代码如下：

标准模块：
Option Explicit
Public Const EWX_SHUTDOWN = 1 '关闭系统

Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, _
　　 ByVal dwReserved As Long) As Long

窗体模块：

Option Explicit
Dim txtTime　　 '保存输入时间
Dim nowTime　　 '保存实时时间
Dim oldTime　　 '保存开始定时时间

Private Sub Command1_Click()
　 oldTime = Time
　 If Not IsDate(Text1.Text) Then '用IsData函数判断输入的时间格式
　　　 MsgBox "你所输入的不是时间格式,请重试!", , "Wrong"
　 Else
　　　 txtTime = TimeValue(Text1.Text)
　 End If
　 Timer1.Enabled = True　 '启动定时器
　 Me.WindowState = 1　　 '最小化窗体
End Sub

Private Sub Timer1_Timer()
　 nowTime = Time
　 If Option1(0).Value Then
　　　 If DateDiff("s", nowTime, txtTime) Then
　　　　 If DateDiff("s", nowTime, txtTime) < 0 Then
　　　　　 '用DateDiff函数判断是否到时间了
　　　　　　 If Not ExitWindowsEx(EWX_SHUTDOWN, 0) Then
　　　　　　　　 MsgBox "无法关闭计算机"
　　　　　　 End If
　　　　 End If
　　　 ElseIf DateDiff("s", nowTime, oldTime + txtTime) < 0 Then
　　　　 If Not ExitWindowsEx(EWX_SHUTDOWN, 0) Then
　　　　　　　 MsgBox "无法关闭计算机"
　　　　 End If
　　　 End If
　　 End If
End Sub

　结束语：以上程序在VB5.0/6.0和Win98上调试通过。其实，此程序还可增加一些花样，譬如，最后窗体不是最小化，而是调用Win32 API函数，把她的图标放在系统任务栏里，即在右下角有声音，时间等图标的地方，那是另外一个主题了。

　 (版主注：此文有bug，Command1_Click过程改为下述代码为好)

附：

Private Sub Command1_Click()
　 oldTime = Time
　 If Not IsDate(Text1.Text) Then '用IsData函数判断输入的时间格式
　　　 MsgBox "你所输入的不是时间格式,请重试!", , "Wrong"
　 Else
　　　 txtTime = TimeValue(Text1.Text)
　　 Timer1.Enabled = True　 '启动定时器
　　 Me.WindowState = 1　　 '最小化窗体
　 End If
End Sub
这是定时关机代码
