请教：关于全局热键设置的问题

Question

就算你的程序被挂起来了，也可以接收到热键

Answer 1

// 注册你想要监视的热键  windows的logo +A
if(!::RegisterHotKey(this->GetSafeHwnd(),0x3000,MOD_WIN,0x41 ) )
{  ::AfxMessageBox("热键注册失败！");

}

// 监视 ctrl + a
::RegisterHotKey(this->GetSafeHwnd(),0x3001,MOD_CONTROL,0x41 );
::RegisterHotKey(this->GetSafeHwnd(), 0x3002 , MOD_CONTROL | MOD_SHIFT, 'A'); // 单独的a
::RegisterHotKey(this->GetSafeHwnd(),0x3003,0,0x41 );    2   定义 热键的消息响应和映射  头文件 源文件 消息映射宏 3个地方
        afx_msg LRESULT OnHotKey(WPARAM wParam,LPARAM lParam);
        LRESULT CHotKeyDlg::OnHotKey(WPARAM wParam,LPARAM lParam)
        ON_MESSAGE(WM_HOTKEY,OnHotKey) LRESULT CHotKeyDlg::OnHotKey(WPARAM wParam,LPARAM lParam)
{
if ( 0x3000 == wParam)
{
AfxMessageBox(" windows的logo + A");
}
else if ( 0x3001 == wParam)
{
AfxMessageBox(" Ctrl + A ");
}
else if ( 0x3002 == wParam)
{
AfxMessageBox(" Ctrl + shift + A");
}
else if ( 0x3003 == wParam )
{
AfxMessageBox("  单独的 A ");
} return 1;
}    3   释放热键
        ::UnregisterHotKey(m_hWnd,0x3000);
