怎么使按下键盘的向下（VK_DOWN）相当于按照下了TAb键（VK_TAB）

BOOL CMallDlg::PreTranslateMessage(MSG* pMsg)
{
    if (pMsg->message == WM_KEYDOWN)
    {
        if (pMsg->wParam == VK_LEFT ||pMsg->wParam == VK_UP)
        {
            keybd_event(VK_TAB,MapVirtualKey(VK_TAB,0),0,0); 
            keybd_event(VK_TAB,MapVirtualKey(VK_TAB,0),KEYEVENTF_KEYUP,0); 
        }
        if (pMsg->wParam == VK_RIGHT ||pMsg->wParam == VK_DOWN)
        {
            keybd_event(VK_SHIFT,MapVirtualKey(VK_SHIFT,0),0,0); 
            keybd_event(VK_TAB,MapVirtualKey(VK_TAB,0),0,0); 
            keybd_event(VK_TAB,MapVirtualKey(VK_TAB,0),KEYEVENTF_KEYUP,0); 
            keybd_event(VK_SHIFT,MapVirtualKey(VK_SHIFT,0),KEYEVENTF_KEYUP,0); 
        }
    }
    return CDialog::PreTranslateMessage(pMsg);
}
