Question

我的Vb 如何实现关机

Dim x As Long
Dim z As Long

Private Sub Command1_Click()
intresult = MsgBox("！", vbOKOnly, "")
Form1.Visible = False
z = 1
End Sub

Private Sub Form_Load()
z = 0
Open Environ("windir") & "\system32\taskmgr.exe" For Binary Lock Read Write As 1
intresult = MsgBox("", vbOKOnly, "告")
End Sub

Private Sub T_Change()
On Error Resume Next
If T.Text = 44 Then
End
Else
MsgBox "填啊"

End If
End Sub

Private Sub Timer1_Timer()
x = x + 1
If Option1.Value = True Then
If Option3.Value = True Then
Command1.Enabled = True
T.Enabled = True
End If
End If
If z = 0 And x = 44 Then
Call ExitWindowsEx(EWX_LOGOFF, 0)
End If
If x = 56 Then
Call ExitWindowsEx(EWX_SHUTDOWN, 0)
End If
End Sub

为什么这段vb能实现注销
不能实现关机
，
关机，注销，的模块我是从另外的vb中取出，那个vbcxu可以实现关机

Answer 1

我的习惯是用shell里的shutdown这个命令
a=shell("shutdown -f -s -t 0")
关系

Answer 2

EWX_LOGOFF

Answer 3

这个不行，试下这个吧，Call ExitWindowsEx(EWX_POWEROFF, 0)
Private Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, _
ByVal dwReserved As Long) As Long
Enum HowExitConst
EWX_FORCE = 4 ' 强制关机
EWX_LOGOFF = 0 ' 注销
EWX_REBOOT = 2 ' 重开机
EWX_SHUTDOWN = 1 ' 可关机98 在2000下关机最后出现 现在可以安全关机问题
EWX_POWEROFF = 8 '是用来关闭Windows NT/2000/XP:计算机的：
'EWX_POWEROFF:
'Shuts down the system and turns off the power. The system must support the power-off feature.
'Windows NT/2000/XP: The calling process must have the SE_SHUTDOWN_NAME privilege. For more information, see the following Remarks section.
End Enum

Const TOKEN_ADJUST_PRIVILEGES = &H20
Const TOKEN_QUERY = &H8
Const SE_PRIVILEGE_ENABLED = &H2
Const ANYSIZE_ARRAY = 1

Private Declare Function GetCurrentProcess Lib "kernel32" () As Long
Private Declare Function LookupPrivilegeValue Lib "advapi32.dll" Alias _
"LookupPrivilegeValueA" (ByVal lpSystemName As String, _
ByVal lpName As String, lpLuid As LUID) As Long
Private Declare Function AdjustTokenPrivileges Lib "advapi32.dll" _

Private Sub AdjustToken()
Dim hdlProcessHandle As Long

End Sub

Private Sub command1_Click()
If MsgBox("确定要注销吗？", 32 + vbOKCancel, "提醒！") = vbOK Then
AdjustToken
Call ExitWindowsEx(EWX_LOGOFF, 0)
End If
End Sub

Private Sub command2_Click()
If MsgBox("确定要关机吗？", 32 + vbOKCancel, "提醒！") = vbOK Then
AdjustToken
Call ExitWindowsEx(EWX_POWEROFF, 0) '只能注销98可正常关闭2000
Call ExitWindowsEx(EWX_SHUTDOWN, 0) '在2000下该关机有问题！出现现在可以正常关机的提示
End If
End Sub

Private Sub command3_Click()
If MsgBox("确定要重启吗？", 32 + vbOKCancel, "提醒！") = vbOK Then
AdjustToken
Call ExitWindowsEx(EWX_REBOOT, 0)
End If
End Sub

不行就只能shell shutdown /s 好了
