Property pages of different sizes in same sheet.

Hi,

I have some property pages that are of different sizes ,Now I have made it
so that when the user clicks on continue button on first page, a new page is
added but since that page is larger(in both width and height) from the
previous page it does appear completely in that sheet. what shall I do to
resize the sheet accordingly?

and here is the code:

void CCAdsDlg::OnBnClickedScr()
{
    SCRForm1Dlg* dlg = new SCRForm1Dlg;
    CPropertySheet* sheet = new CPropertySheet;
    dlg->pWnd = sheet;
    sheet->AddPage(dlg);
    ASSERT_VALID(dlg);
    sheet->SetTitle("Preliminary Information");
    sheet->Create();
    sheet->ShowWindow(SW_SHOWDEFAULT);
}

and then in SCRForm1Dlg

void SCRForm1Dlg::OnBnClickedContinue()
{
    SCRForm2Dlg* dlg = new SCRForm2Dlg;
               //this(SCRForm2Dlg) page is larger than SCRForm1Dlg but
appears according to the size of SCRForm1Dlg.
    dlg->pWnd = pWnd;
    pWnd->AddPage(dlg);
    pWnd->SetTitle("Personnel Information");
    pWnd->SetActivePage(dlg);
}

both SCRForm1Dlg , SCRForm2Dlg are CPropertyPage derived classes.
