VC下给CDialog添加加速键(Add accelerators)

为CDialog添加加速键:

//在头文件声明成员变量
HACCEL m_hAccelTable;
 
//在构造函数中调用函数,加入加速键
CMyDlg::CMyDlg(CWnd* pParent /*=NULL*/)
        : CDialog(CMyDlg::IDD, pParent)
{
        //{{AFX_DATA_INIT(CMyDlg)
        //}}AFX_DATA_INIT
        // Note that LoadIcon does not require a subsequent DestroyIcon in Win32
        m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
 
        //加速键
        m_hAccelTable = ::LoadAccelerators(AfxGetInstanceHandle(),
                MAKEINTRESOURCE(IDR_ACCELERATOR)); //加速键的资源ID
}

//添加PreTranslateMessage消息相应
BOOL CMyDlg::PreTranslateMessage(MSG* pMsg) 
{
        // TODO: Add your specialized code here and/or call the base class
 
        //加速键事件
        if(m_hAccelTable != NULL)   
        {   
                if(TranslateAccelerator(m_hWnd, m_hAccelTable, pMsg))
                {
                        return TRUE;  
                }
        }
        
        return CDialog::PreTranslateMessage(pMsg);
}
