用windows修改器设置全局热键

windows api中的register hot key将允许您注册全局热键。您还需要使用globaladdatom来获取唯一的热键标识符。见 this link 详细情况。

Private Declare Function RegisterHotKey Lib "user32" (ByVal hwnd As Long, ByVal id As Long, ByVal fsModifiers As Long, ByVal vk As Long) As Long
Private Declare Function GlobalAddAtom Lib "kernel32" Alias "GlobalAddAtomA" (ByVal lpString As String) As Integer

Private Const WM_HOTKEY As Long = &H312
Private Const MOD_WIN          As Long = &H8

  m_lHotkey = GlobalAddAtom("MyHotkey")
  Call RegisterHotKey(Me.hwnd, m_lHotkey, MOD_WIN, vbKeyO)

然后你只需要听一下窗口上的wm_热键信息。
