...
 CControlPos m_cControlPos;

2. In the OnInitDialog (or InitialUpdate) function, set the object's parent window

BOOL CYourDialog::OnInitDialog()
...
 m_cControlPos.SetParent(this);
...

3. After the call to CControlPos::SetParent, Add the controls you want to resize.

m_cControlPos.AddControl(IDOK, CP_MOVE_HORIZONTAL);
m_cControlPos.AddControl(IDCANCEL, CP_MOVE_HORIZONTAL);

4. Finally, on your WM_SIZE handler, call the object's MoveControls to specify runtime behaviour. move all of the controls. Controls can be moved horizontally and vertically and resized horizontally and vertically.

void CYourDialog::OnSize(UINT nType, int cx, int cy) 
{
 CDialog::OnSize(nType, cx, cy);
	
 m_cControlPos.MoveControls();
}
