14.2.3..The Screen and Client Coordinates..................................................

When calling either the GetClientRect() or the GetWindowRect() methods to get the

location and the dimensions of a control or another object, it is important to know the

origin of the produced rectangle. By default, the rectangle returned by the

GetWindowRect() method called by a control has its origin on the top left corner of the

monitor and not on the top-left corner of the parent window. Consider the following

event. It gets the location and dimensions of a control and stores them in a CRect

variable. Then it paints a rectangle (it is supposed to paint the control) located on, and

equal to the dimensions of, the control:

void CTabDlg::OnBtnInfo()

{

// TODO: Add your control notification handler code here

CRect Recto;

m_Panel.GetWindowRect(&Recto);

CClientDC dc(this);

CBrush BlueBrush(RGB(0, 128, 192));

CBrush *pOldBrush = dc.SelectObject(&BlueBrush);

dc.Rectangle(Recto);
