MFC，光标区域内变化的问题

BOOL CChildView::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{

if(nHitTest == HTCLIENT)
{
CPoint point;
::GetCursorPos(&point);
ScreenToClient(&point);
CRect rect(496, 528, 524, 564);
if(rect.PtInRect(point))
::SetCursor(AfxGetApp()->LoadCursor(IDC_HAND));
else
::SetCursor(AfxGetApp()->LoadStandardCursor(IDC_CROSS)); //2
return TRUE;
}
-----------------------------------------------------------------------------

我已经设置了在一个区域矩形内光标变化，但是我还想设置另一个区域例如rect(442,528 , 474, 564)，应该怎么添加程序

if(rect.PtInRect(point) || rect1.PtInRect(point)) )
::SetCursor(AfxGetApp()->LoadCursor(IDC_HAND));
else
::SetCursor(AfxGetApp()->LoadStandardCursor(IDC_CROSS)); //2

在MouseMove事件里，获取当期鼠标点的位置，若点在矩形区域内，则改变鼠标形状，
