如何使用一个预定义的Windows光标

调用CWinApp:: LoadStandardCursor并传送光标标识符。
     BOOL CSampleDialog:: OnSetCursor (CWnd* pWnd, UINT nHitTest, UINT message)
{
     //Display wait cursor if busy.
     if (m_bBusy)
     {
         SetCursor (AfxGetApp () ->LoadStandardCursor (IDC_WAIT));
         return TRUE;
     return CDialog:: OnSetCursor (pWnd. nHitTest,message);
    调用SDK函数GetSystemMetrics，该函数可以检索有关windows显示信息，诸如
//Initialize CSize object with screen size.
CSize sizeScreen (GetSystemMetrics (SM_CXSCREEN))
