This tip shows you how to convert the dimension values in the .rc file of a dialog into pixels

Given a rectangle rcDlg which contains the rc file coordinates of a dialog resource, use the following code:

CDialog *pDlg = m_pDlg;
 pDlg->MapDialogRect(&rcDlg);
 ::AdjustWindowRectEx(&rcDlg,
                             pDlg->GetStyle(),
        ::IsMenu(::GetMenu(pDlg->GetSafeHwnd())),
                             pDlg->GetExStyle());

 pDlg->ClientToScreen(&rcDlg);

P.S. Special thanks goes to Jacques Raphanel for this solution.
