在你的CSxDlg中的 加上一句就可以了

void CSxDlg::OnLButtonUp(UINT nFlags, CPoint point)

{

    // TODO: Add your message handler code here and/or call default

    x2=point.x;

    y2=point.y;

    MyNewPen.DeleteObject( ); //就是加上这句话,就可以了,我试过是可以的.

    UpdateData(FALSE);   

    CDialog::OnLButtonUp(nFlags, point);

}

When an application no longer requires a given pen, it should call the CGdiObject::DeleteObject    member function or destroy the CPen object so the resource is no longer in use. An application should not delete a pen when the pen is selected in a device context.
