热键的注册于释放

热键的注册函数：

BOOL RegisterHotKey(
  HWND hWnd,         // handle to window
  int id,            // hot key identifier
  UINT fsModifiers,  // key-modifier options
  UINT vk            // virtual-key code
);

应用例子：

RegisterHotKey(this->m_hWnd,100,MOD_CONTROL,VK_F12);

热键释放函数：

BOOL UnregisterHotKey(
  HWND hWnd,  // handle to window
  int id      // hot key identifier
);

应用例子：

UnregisterHotKey(this->m_hWnd,100);

消息响应函数：

LRESULT ChootKeyDlg::OnHotKey(WPARAM wParam,LPARAM lParam)

{
typedef void (WINAPI *PROCSWITCHTOTHISWINDOW) (HWND, BOOL);
PROCSWITCHTOTHISWINDOW SwitchToThisWindow;


HMODULE hUser32 = GetModuleHandle(_T("user32"));


SwitchToThisWindow = ( PROCSWITCHTOTHISWINDOW)GetProcAddress(hUser32, "SwitchToThisWindow"); 


SwitchToThisWindow(this->m_hWnd,TRUE);


MessageBox(_T("热键注册成功-恭喜！"));


return 0;
