MFC CHotKeyCtrl控件

知识点：
CHotKeyCtrl控件
获取热键数据
注册热键
响应热键事件

一、CHotKeyCtrl控件
void SetHotKey( WORD wVirtualKeyCode, WORD wModifiers );
二、获取热键数据
DWORD GetHotKey( ) const;
void GetHotKey( WORD &wVirtualKeyCode, WORD &wModifiers ) const;
三、注册系统热键
RegisterHotKey
The RegisterHotKey function defines a system-wide hot key.
BOOL RegisterHotKey(
  HWND hWnd,        // window to receive hot-key notification
  int id,           // identifier of hot key
  UINT fsModifiers, // key-modifier flags
  UINT vk            // virtual-key code
);
四、响应热键事件
GetParent
WM_HOTKEY


//获取热键值
    CHotKeyCtrl* phot=(CHotKeyCtrl*)GetDlgItem(IDC_HOTKEY1);
    WORD vkey,fsModifiers;
    phot->GetHotKey(vkey,fsModifiers);
    BOOL r=RegisterHotKey(m_hWnd,111,fsModifiers,vkey);
    TRACE("注册热键==%d \n",r);
    //注册热键功能

static bool flag=true;
     if (nHotKeyId==111)
     {
        GetParent()->ShowWindow(flag);
         flag=!flag;
     }
    CDialog::OnHotKey(nHotKeyId, nKey1, nKey2);
