在Windows中关闭显示器
可以使用SendMessage()或PostMessage()消息API向系统发送关闭监视器的要求：
Option Explicit
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Const HWND_BROADCAST = &HFFFF&
Private Const WM_SYSCOMMAND = &H112
Private Const SC_MONITORPOWER = &HF170&
Private Const MONITOR_OFF = 2
Private Sub Form_Load()
SendMessage Me.hwnd, WM_SYSCOMMAND, SC_MONITORPOWER, ByVal MONITOR_OFF
End
End Sub
命令行：
powershell (Add-Type '[DllImport(\"user32.dll\")]^public static extern int PostMessage(int hWnd, int hMsg, int wParam, int lParam);' -Name a -Pas)::PostMessage(-1,0x0112,0xF170,2)
