void CStyleView::OnLButtonDown(UINT nFlags, CPoint point)
{
        // TODO: Add your message handler code here and/or call default
       
SetClassLong(m_hWnd,GCL_HCURSOR,(LONG)LoadCursor(::AfxGetInstanceHandle(),MAKEINTRESOURCE(IDC_CURSOR1)));
        CView::OnLButtonDown(nFlags, point);
}

void CStyleView::OnLButtonUp(UINT nFlags, CPoint point)
{
        // TODO: Add your message handler code here and/or call default
SetClassLong(m_hWnd,GCL_HCURSOR,(LONG)LoadCursor(::AfxGetInstanceHandle(),MAKEINTRESOURCE(IDC_CURSOR2)));

        CView::OnLButtonUp(nFlags, point);
}
为什么我按下鼠标和放开鼠标左键，鼠标图形不立即改变而一定要移动一下，鼠标图形才能改变

这可能需要重绘，你加一个Invalidate()试一下

试着在SetClassLong后, 手工发一个WM_SETCURSOR
