Hi,

I had a dialog application with some buttons. But while re-sizing the dialog, the buttons are not automatically repositioned.

Could you please help me to fix this problem, thanks in advance.

Try to react to the WM_SIZE dialog's message,
then to move your controls explicitly :)

C++

// CPoint CYourDialog::m_cLastClientBottomRight
// is initalized in CYourDialog::OnInitDialog()
// as right-bottom point of its client rectangle

// Assumed, the OK button must be adapted in both directions:
void CYourDialog::OnSize(UINT nType, int cx, int cy)
{
  CRect crClient;
  GetClientRect(crClient);

  if (m_cBtnOK.GetSafeHwnd()) {
    CRect crControl;
    m_cBtnOK.GetWindowRect(crControl);
    ScreenToClient(crControl);

    crControl.OffsetRect(crClient.BottomRoght() - m_cLastClientBottomRight);
    m_cBtnOK.MoveWindow(crControl);
    m_cBtnOK.Invalidate();
  }

  m_cLastClientBottomRight = crClient.BottomRight();
}
