让 Windows Media Player 在锁定 PC 时暂停并在解锁时再次播放？

正如标题所说，我希望能够让 Windows Media Player 在锁定我的电脑时暂停，并在解锁后再次播放。

这可能吗？

我确实尝试使用这个 AutoHotKey 脚本来做到这一点：

;---------------------------------------------------------------
;Notify Lock\Unlock
;   This script monitors LockWorkstation calls
;
;   If a change is detected it 'notifies' the calling script
;      On Lock
;         This script will call function "on_lock()"
;      On Unlock
;         This script will call fucntion "on_unlock()"
;IMPORTANT: The functions "on_lock()" and "on_unlock()" DO NOT
;exist in this script, they are to be created in the script that
;calls notify_lock_unlock() (presumably your main script)

;Initialize global constants
WTS_SESSION_LOCK      :=   0x7
WTS_SESSION_UNLOCK      :=   0x8
NOTIFY_FOR_ALL_SESSIONS   :=   1
NOTIFY_FOR_THIS_SESSION   :=   0
WM_WTSSESSION_CHANGE   :=   0x02B1

notify_lock_unlock()
{
   Global WM_WTSSESSION_CHANGE
   Global NOTIFY_FOR_ALL_SESSION

   hw_ahk := FindWindowEx( 0, 0, "AutoHotkey", a_ScriptFullPath " - AutoHotkey v" a_AhkVersion )

   OnMessage( WM_WTSSESSION_CHANGE, "Handle_WTSSESSION_CHANGE" )

   success := DllCall( "wtsapi32.dll\WTSRegisterSessionNotification", "uint", hw_ahk, "uint", NOTIFY_FOR_ALL_SESSIONS )

   if( ErrorLevel OR ! success )
   {
      success := DllCall( "wtsapi32.dll\WTSUnRegisterSessionNotification", "uint", hw_ahk )
      ;If DLL registration fails, wait 20 seconds and try again
      Sleep, 20000
      notify_lock_unlock()
      ;MsgBox, [WTSRegisterSessionNotification] failed: EL = %ErrorLevel%
   }
   return
}

Handle_WTSSESSION_CHANGE( p_w, p_l, p_m, p_hw )
; p_w  = wParam   ;Session state change event
; p_l  = lParam   ;Session ID
; p_m  = Msg   ;WM_WTSSESSION_CHANGE
; p_hw = hWnd   ;Handle to Window
{
   Global WTS_SESSION_LOCK
   Global WTS_SESSION_UNLOCK

   If ( p_w = WTS_SESSION_LOCK )
   {
      on_lock()
   }
   Else If ( p_w = WTS_SESSION_UNLOCK )
   {
      on_unlock()
   }
}

FindWindowEx( p_hw_parent, p_hw_child, p_class, p_title )
{
   return, DllCall( "FindWindowEx", "uint", p_hw_parent, "uint", p_hw_child, "str", p_class, "str", p_title )
}

notify_lock_unlock()
; Calls function "on_lock()" when computer is locked and "on_unlock()" when computer is unlocked

on_lock()
{
   Send, {Media_Play_Pause}
}

on_unlock()
{
   Send, {Media_Play_Pause}
}

只要我在媒体播放器上播放内容，它就能正常工作。如果它暂停了，那么当我锁定 PC 时它就会开始播放。

我似乎找不到 Windows Media Player 暂停/播放的任何命令行选项。

有人知道如何让这个脚本正常工作吗？或者如果你有更好的想法，请告诉我。

尝试一下这个小程序。

对于 Chris F 来说 - 这是一个在您锁定 PC 时关闭显示器、暂停媒体播放器并将 IM 程序置于 AFK 状态的程序。
